Cameras are cool, but there are nuances
Yes, in many ways, the cameras of the new flagship are cooler than last year’s cameras. But not in everything.
So, the focusing distance has changed. For close-up shots, the new iPhone should be held about 3 or even 4 cm farther from the subject than the old one. With macro photography, this can cause big problems. And this is very strange. In addition, the 11 Pro Max had a lighter telephoto lens, with the optical zoom the quality was higher
The battery is a cant
Miracles are not worth waiting for. The new item has a smaller battery capacity. But in most cases, the smartphone works as long as its predecessor. But in the same games it discharges almost several times faster. Very strange, yeah?
Manual: iPhone 11 Pro Max 512gb | Beginners Guide Tips & Tricks
Yes, it’s nice to watch a movie on it. But using a 6.7-inch shovel every day is not always comfortable. Unless, of course, you are Gulliver. Using the iPhone 12 Pro Max with one hand is even less convenient than the iPhone 11 Pro Max. We don’t even talk about girls.
the main disadvantages of the iPhone 12 Pro Max. some of the flagship can literally enrage
The flagship iPhone 12 Pro Max is really cool. It has the best screen, top-end camera, and lasts longer than three other iPhones 12. But there are also disadvantages.
Old design in a new format
The iPhone 5 was great. For its size. The iPhone 12 Pro Max is good too. But only when you just look at him. For a huge smartphone, this design is hardly suitable. The ends of the device, which, by the way, weighs as much as 226 grams, literally dig into the skin on the fingers. If you have a normal palm size, in half an hour you will get tired of Pro Max
The box is empty
The iPhone 12 Pro Max comes standard with only a cord, a couple of papers, a sticker, and the iPhone itself. For a premium device for over 100 thousand rubles, it is absolutely monstrous. You will have to buy a quick charger. Headphones too.
iPhone 11: technical and operational characteristics
Currently, Apple’s technology is very popular all over the world. One of its recognized leaders is the iPhone. These modern smartphones are distinguished by unique functionality and performance, thanks to which a huge number of people choose them among the wide variety of smartphones on the market today. Therefore, it is not surprising that the recently appeared novelty attracted great attention to itself. Apple iPhone latest model 2019.
Among all the capabilities of this iPhone, first of all, one can single out a special camera system, with the help of which it became real to further improve the quality of shooting. The main advantage of the cameras is the ease of working with them, thanks to which each person will be able to create unique photographs that will be distinguished by high definition and brightness. The video quality is also high, which makes this model very popular.

How to turn off iPhone 11, iPhone 11 Pro and Max
Do you know what my wife’s first question was when she got the iPhone 11? How to turn off or restart your phone! I laughed for a long time, then took the device in my hands, pressed the side power button, held it longer but the iPhone was not going to turn off. Here my wife laughed for a long time, looking at my futile attempts. As it turned out, the developers of the “apple” company, for some reason, changed everything, which made those who switched to the iPhone 11 or iPhone 11 Pro from older models such as the iPhone 6s, iPhone 7 or iPhone 8, as well as smartphones on Android. So it turns out that the usual side shutdown button is there, and it is not clear what to do with it.
The fact is that the way to disable on the iPhone 11 and iPhone 11 Pro is significantly different from previous models. There are two ways to turn off this phone and I will show each of them in detail.
How to turn off iPhone 11 with buttons
As I said above, the device has a side power button. With its help, you can turn it off, but there is a little trick!
To turn off iPhone 11, do the following in sequence:
Press the side button and one of the volume buttons at the same time. Any. even an increase in volume, even a decrease. The main thing is not to release the buttons immediately after pressing, otherwise a screenshot of the screen will be taken.
The shutdown menu should appear on the smartphone screen, where you need to move the shutdown slider to the right.
If you suddenly change your mind about turning off the iPhone 11, then just click the “Cancel” button at the bottom of the screen.
Shutting down iPhone 11 through settings
The developers of the iOS operating system have made another fairly simple way to disable the iPhone 11 (pro, max, etc.). To do this, go to its settings and open the “Basic” section.
Scroll down the menu. At the very end there will be an item “Turn off”. Click it:
The iPhone shutdown menu appears. There, just drag the slider with your finger from left to right.
It remains to wait until the smartphone turns off.
Of course, there is no point in turning off your iPhone often. For some, it works without turning off for months, but situations arise differently and you need to know the main features of your phone! Good luck to all!
Which to choose. iTunes or iCloud?
You may prefer to use iTunes backup instead of iCloud backup. If you do this, keep in mind that it can take much longer. Also make sure you check the box in iTunes to encrypt the backup.
If you have a fast internet connection, it is better to do the recovery using iCloud. it is much faster. Otherwise, iTunes recovery might be the way to go. Remember, if your Mac is running macOS Catalina, you’ll have to use Finder instead of iTunes for backups and restores.
These are the three main ways to set up your new iPhone. Of course, advanced users probably already know all the subtleties, but sometimes experienced owners need to spy on certain points, not to mention newbies (if you have any questions, you can find the answers in our Telegram chat). The latter will be much more after these holidays.
Transfer Data from Android to iPhone
For this there is the Move to iOS application. It can only be installed by users of devices running Android. Move to iOS app lets you quickly transfer contacts, photos, and other data from your Android device to your iOS device. In other words, it is intended for those who decide to switch to iPhone.
It is enough to download this application and follow the instructions
Restoring iPhone from Backup
This is the easiest way to switch from your old iPhone to a new one. All you have to do is make sure you have a recent backup from your existing iPhone (or even iPad) and then point your new iPhone 11 to that iCloud backup. It will then download all your settings, apps, passwords, even your wallpapers. When the process is complete. it may take a while, depending on your internet speed and the size of your backup. it will be like you’ve never sold an old iPhone. Even your Safari tabs will stay in place.
The backup time depends on the amount of information on the iPhone
To do this, first go to the iCloud settings on your iPhone and make sure there is a recent automatic backup. If not, just make a new copy manually.
How to set up your new iPhone 11, iPhone 11 Pro, or iPhone 11 Pro Max
Many people prefer to update their smartphone on New Year’s holidays (or give iPhones to loved ones). But it’s one thing if the transition occurs from the iPhone XS to the iPhone 11 Pro, and completely different if the owner of the new smartphone previously had, for example, an iPhone SE or iPhone 6. In recent years, the process of setting up an iPhone has changed as much as ourselves. iPhone. Apple just makes the process easier. And setting up your new iPhone 11 from scratch is just as easy as it used to be. gone are the days of manually copying passwords just to get to your home screen.
Many people find it difficult to set up an iPhone. But everything is very simple
However, there are a few more tricks to get you started using your phone quickly. Let’s see how to properly set up your new iPhone.
Automatic iPhone setup
This fantastic feature was introduced in iOS 11. Just bring your old and new devices close together when prompted, and auto setup will copy your Apple ID and all settings. It’s kind of like AirDrop, with only one specific purpose.
This window appears automatically as soon as you bring up your new iPhone.
When you start your new iPhone for the first time, any nearby iOS devices will detect it and prompt for automatic setup. The new device will display a cloud-like dot pattern on the screen. Just use your old device’s camera to “scan” this pattern as a QR code. Your iCloud login, Wi-Fi passwords and everything else you need are transferred automatically. This is really amazing.
To use migration, you must have an iPhone with iOS 12.4 or later
If you can’t use your current iPhone’s camera, tap Manual Authentication and follow the onscreen instructions. Both iPhones must be nearby and connected to a power source until the data migration process is complete.
Longreads for you
Apple computers are renowned for their quality and ease of use, but like any other technology, they are not immune to breakdowns. over, though to get out of
Black Friday continues to delight interesting discounts. this time the sale was organized by the developers of software for recovering data on iPhone and fixing iOS errors. Something is generally given away for free!
bono_denis, No, it won’t. A week ago, I quietly switched from iPhone 3gs (iOS 6.1.6) to iPhone 5s (iOS 12.4.4)
Chinese power adapter (charger)
I don’t even want to consider Chinese chargers. And I do NOT recommend using them! Why? Because most of them are of dubious quality! over, the characteristics declared by the manufacturer almost always differ from the real ones.
It’s your right to use them, but when smoke comes out of your iPhone and it stops charging, you will remember what I told you.
A separate article is on the way in which we will analyze how to distinguish the original power adapter for the iPhone from the Chinese counterfeit.
Charging your new iPhone correctly
There are many theories about how to properly charge your new iPhone. I’ll tell you how I usually do it myself. There is nothing like that, just if you think sensibly, then the first couple of charging cycles are best done according to the instructions below:
- After pulling the iPhone out of the box, connect it to the charger
- After the iPhone is charged to 100%, feel free to use it and bring it to a full discharge
- After the battery is completely discharged and the iPhone turns off, reconnect it to the charger
- Charge your phone to 100% without using it while charging.
It is best if you do a couple of full charge / discharge cycles. After that, you can charge the phone as you used to do it before. Read about the rest of the nuances below.
Car chargers are generally EVIL. specifically, CHEAP CHINESE car chargers greatly increase the chances of you ditching your iPhone‘s charge / power controller. I advise everyone to familiarize themselves with this problem, which I wrote about in detail in a separate article “Replacing the iPhone power and charging controller” (link).
The thing is that the car power grid is far from the standard in terms of voltage / current stability, and those cheap car chargers that many use cannot protect the phone from surges in the car power network.
If you are faced with a problem when your phone has stopped charging, “does not accept” even the original charging and cable, it takes a very long time or does not fully charge. most likely the problem is in a damaged charging controller. And believe me, in 90% of such cases, car chargers are to blame.
If you do spend most of your day on the road and need to recharge your iPhone from your car’s cigarette lighter, don’t press on when buying a car charger. Better to overpay a couple of dollars, but get a known high-quality branded item.
Personally, I like the products of the Ugreen company, which I wrote about above. All the products I purchased from them inspire confidence and really work. The simplest one for 5V and 1A (which is just suitable for charging an iPhone in a car) costs 6.99.
Non-original Lightning cable
This is the case with lightning cables. As you know, there is a chip inside the lightning plug, which is used for device authentication and a number of other functions. Without this chip (microcircuit), the cable simply will not be accepted by the iPhone itself.
Apple has partnered with some iOS device accessory manufacturers to supply Lightning chips only to authorized ones. Products from such manufacturers are usually marked MFI (Made For iPhone).
The Chinese, in turn, managed to make a clone of this chip and successfully use it in cables, which are then sold for 0.98 on the AliExpress website. Although such cables work, they usually do not last long.
I have tried many cables and I can say the following. I have nothing against non-original Lightning cables, but I still advise you to purchase them for more / less adequate money.
What you get for 0.98 just can’t match the quality of the original. I strongly advise everyone to use an excellent lightning cable from Ugreen, which is certified by Apple, of high quality and solid.
Which power adapter to use
A standard iPhone power adapter (5V, 1A, 5W) fully charges an average phone in about 1 hour 30 minutes. I can’t say anything more about this adapter. Well, he is ordinary
A bit of theory about Apple power adapters. They all have a voltage of 5 volts (V), but different amperage, which is measured in amperes (A) and power, which is measured in watts (W). These three quantities are related to each other by a simple formula: V x A = W.
- Example 1: 5V and 1A power adapter has 5W power (standard iPhone charging)
- Example 2: a 5V and 2.1A power adapter will already have a power of 10W (charging for iPad)
Can I use an iPad power adapter to charge my iPhone? The answer to this question is YES, POSSIBLE. And here the smartest of you has to say “Why are you soaring again! It’s bad for the battery! ” Good good! Let’s take a look at this issue too
First! Apple’s official website has a page on which it says in black and white “Despite the fact that the power adapter is designed for iPad, you can also charge any model of iPhone or iPod with it” And they wrote this not at all because they want to sell you a new battery as soon as possible.
Yes, there really is a myth that charging an iPhone with an iPad charger can quickly ruin your phone’s battery. I can assure you this is completely wrong! The charger (as we used to call it. charging) that you plug into an outlet is not a charger at all, but a regular DC power adapter.
The iPhone charging is located inside the iPhone itself and is the very same charging controller. which we talked about above. It is this module that decides what amperage to use when charging the iPhone battery.
There is another myth that the iPad charger can charge the iPhone 2 times faster. Unfortunately, this is not entirely true. Only starting with the sixth generation of the iPhone, Apple taught its phones fast charging from an adapter for the iPad, and even then not 2 times faster. Previous iPhones do not have this feature.
How to properly charge your iPhone. a dummy’s guide
I’m sure each of you charges your iPhone in a chaotic manner. Having a “power reserve” of the battery equal to one astronomical day, we always try to recharge on the go even if by at least 10-20%.
On the other hand, almost every night our iPhones “roast” on a charge for more than 7 hours. In this article, we’ll find out how to properly charge your iPhone and how these messy charger connections affect battery life. Go!
Well, now one of you will say, “Chuva-ah-ah, why are you rubbing us for game…. “. I agree no one ever has any special questions about charging an iPhone.
There are a couple of interesting nuances that not many people know about. So, I tried to collect all these nuances and put them in one article For your general development! Read. it will be informative and interesting!

25 Tips and Tricks iPhone 11 Pro Max
Should I leave my iPhone charging overnight??
In order to answer this question, you need to clearly understand what happens to your iPhone after connecting to the power adapter. It should be said right away that the charging process of the iPhone battery (like any modern gadgets) is controlled by the charging controller built into the iPhone.
This controller does not overcharge the battery, while at the same time endeavors to recharge it as soon as reasonably possible. At the same time, up to 80% of the battery is charged at a fairly fast rate, and the last 20%, on the contrary, in slow motion.
Once the battery is charged, the charging controller cuts off the power supply. The battery is, as it were, left alone, without transferring or taking away the charge from it. In this case, the phone itself is powered from the charger.
In other words, during this period of time, the battery is NOT charging or discharging. Therefore, the myth that after reaching 100% charge, the battery goes into a cyclic discharge / recharge mode is complete nonsense. If this were the case, the battery would be subject to additional wear and tear. What nobody really needs.
Okay Now let’s look at one more fact. Any battery is prone to “self-discharge”. This is a completely normal process of losing power, provided the battery is not connected to anything. Lithium polymer batteries have a self-discharge rate of 5% per month, which is actually very low (compared to other types of batteries).
The charge controller, of course, periodically checks the remaining battery charge and if it detects a significant loss of charge, it will start a new charge cycle. This situation will arise only after the loss of at least 2% of the charge, which in turn can occur no more than once every two weeks.
Thus, if you leave your iPhone on charge for a full month, the built-in battery may be recharged once or twice.
CONCLUSION: From the above, it follows that BY LEAVING THE iPhone ON CHARGING FOR THE WHOLE NIGHT, YOU DO NOT HARM IT AT ALL.
How to erase content and settings from iPhone
If you have access to the iPhone menu that needs to be reset to a new device state, the method below will work for you. To complete the following steps, you do NOT need a computer with a cable and iTunes software. All the necessary functionality is already included in the iOS Settings.
STEP 1. Since we will be doing a complete cleaning of the iPhone, make sure that there is no important data left on it. As in the first part, if necessary, create a backup copy of the iPhone.
STEP 2. Make sure Find My iPhone is off: iCloud Settings Find My iPhone.
STEP 3. Now go to Settings General Reset and click Erase Content and Settings. Confirm your wish with “Erase iPhone”.
STEP 4. All personal information and iPhone settings will be deleted. IOS version will remain the same as before the reset.
How to reset iPhone to factory settings [Instructions]
If you have finally decided to sell your iPhone or are experiencing some difficulties with the firmware, then this instruction will definitely come in handy in which I told you how to reset the iPhone to factory settings. As a result of the reset, the latest version of iOS will be installed on your device. All data from the iPhone will be deleted.
I often advise friends and readers on the site to reset the iPhone in situations when the device starts to glitch or work slowly. The same steps must be taken before selling your iPhone.
You don’t want someone to be able to view your photos, home videos, and get a list of all your contacts and personal messages as well? Below I have given several ways Depending on the state of your device, you can perform at least one of them.
You can reset the iPhone both using a computer and on the iOS device itself. Therefore, we will divide our lesson into two parts according to your choice.
How to reset iPhone using a computer
If for some reason you cannot go to the iPhone Settings (the firmware has flown, iCloud Activation Lock, you forgot the numeric unlock password, etc.), then the best way to reset the iPhone would be DFU mode. Use this instruction for iPhone 4s. 7, or this instruction for iPhone X. 8.
If everything is OK with the iPhone, follow the steps below:
STEP 1. If you value the data on your iPhone (iPad), be sure to make a backup before proceeding to the next step.
STEP 2. Connect your iPhone with a cable to your computer and launch iTunes. Click on the device icon (see the picture below):
STEP 3. Click the Restore iPhone button on the right side of the screen. If you see the message “You need to turn off Find My iPhone before”, turn it off in Phone Settings here: iCloud Settings Find iPhone.
You need your Apple ID password to disable this feature. This is done so that no one except the last owner can clear this device, for example, in the event of theft by intruders (who do not know the password of the Apple ID account).
STEP 4. After disabling the “Find iPhone” function, confirm your intentions by clicking on the Restore and Update button.
STEP 5. The latest version of iOS will be downloaded from the Internet and then installed on your iPhone. All personal data will be deleted.
STEP 6. The next time you turn on your iOS device, you will be prompted to set it up as new or restore from a backup.
STEP 7. The described procedure for resetting iOS devices does not unlink it from your account. In order for the restored device to no longer be listed in your Apple ID account, go to iCloud.com with your Apple ID and delete the required device in the Find iPhone section.
Can’t reset iPhone
Both methods above assume that your iPhone is in working order, i.e. recognized in iTunes or you can go to the phone settings. What to do if your phone is frozen or none of the above methods can restore your iPhone?
First of all, try restarting your device. If the reboot did not work, use the instructions for restoring iPhone firmware in DFU mode (links above).
In this article, I showed you how to reset iPhone to factory settings in two ways. If you have any questions regarding linked accounts, write in the Комментарии и мнения владельцев. Well, if you have learned something useful for yourself, be sure to like it in social networks (buttons below).
We tested the iPhone 11 Pro Max. Hereinafter, we will talk about this particular model. However, the iPhone 11 Pro should differ from it only in the battery life and, of course, in the screen size / resolution. Everything else is identical.
So, the appearance of the novelty largely inherits the iPhone XS Max, it is almost impossible to distinguish them from the front. All visual differences are concentrated on the back. First of all, of course, this is a block with cameras. It is located on a transparent glass platform that rises slightly above the level of the main glass. But the cameras themselves protrude a little.
Immediately after the presentation, the Internet was filled with memes that played up their location. The iPhone 11 Pro has not been compared to anything else: with a stove where the cameras are burners, with an electric razor, with the Terminator’s weapon. I must admit that this decision really looks rather extravagant. But on the other hand, this ensures one hundred percent recognition of the model.
The second feature of the Pro is the body materials. The device is made of stainless steel and polished frosted glass. Those who don’t like the slippery surface of the iPhone XS Max should love the new design. Firstly, it is assumed that it is more reliable in terms of holding the smartphone in hand, and secondly, it is simply beautiful. We had a silver version on testing, and in it the back has an almost pearlescent shade.
Apple claims the new case is also more durable. We, of course, did not dare to arrange a crash test for the device for 132 thousand rubles.
The location of the buttons, slots and connectors has not changed at all compared to the XS Max, so we won’t even dwell on that. But what you immediately feel when you take the Pro Max in your hands is that it has become heavier. Maybe not very much, but you can feel it right away.
Is this good or bad? Everyone decides for himself. Many, as you know, love heavier devices. “so that the hand can feel.” Some, on the contrary, prefer light weight and compactness. In general, this is a matter of taste. But we liked it.
The protagonist of Apple’s September presentation was undoubtedly the new iPhone 11 Pro Max. For the first time, three rear cameras are used here, for the first time it is allowed to submerge in water to a depth of four meters, and the name itself is different from previous generations: the Pro prefix was not added to the iPhone before. So how did the flagship go??
We presented and analyzed the general information and all the details voiced by Apple in the report following the September presentation, so we will not repeat ourselves and move on to testing. Let’s just recall the characteristics of the novelty for a start.
Packaging and equipment
The smartphone comes in a striking black box and a contrasting light image of the back surface of the smartphone body. Note that at some point Apple began to make Accent in the Pro versions of its devices exactly in black. just remember the black mouse and keyboard in the iMac Pro. And now it has come down to the iPhone. However, why not?
The package bundle of the iPhone Pro is almost no different from the iPhone 11, with one significant exception: instead of the standard 5V 1A charging, there is fast charging. 9V 2A here. over, with a USB-C connector.
The iPad Pro is equipped with exactly the same chargers. And this is very convenient: if, for example, you have both an iPad and an iPhone, you can only take one charger and two cables with you on a trip. But it is also convenient that the cable included with the iPhone Pro is Lightning / USB-C, so if you have a MacBook of the latest generations, then you can charge your iPhone from a laptop charger.
Like the iPhone 11, the Pro models run on a new platform. now the Apple A13. The amount of RAM in the iPhone 11 Pro Max, according to Geekbench 5, is 3.65 GB. the same as the iPhone XS Max. There we have ideal conditions for comparing the performance of two SoCs.
Let’s start with the browser benchmarks: SunSpider 1.0.2, Octane Benchmark, Kraken Benchmark and JetStream of the second version. We used the Safari browser on all smartphones. At the same time, iOS on the iPhone XS Max was updated to the current version 13.1.
|104 ms||124 ms|
|49137 points||34019 points|
|611 ms||750 ms|
|129 points||113 points|
The novelty is noticeably faster, and this can be seen in all browser benchmarks. The average growth is 20 percent, but that’s not bad either.
In the complex benchmarks AnTuTu and Geekbench 5, the results are also clear and predictable. In Geekbench, the new product is faster by about 20%.30%. But in AnTuTu, the gap is even wider: almost twice.
The last group of benchmarks is dedicated to GPU performance testing. We used 3DMark, GFXBenchmark Metal, and Basemark Metal, designed specifically for devices with Metal technology.
In GFXBenchmark Metal, all Offscreen tests render images at a fixed resolution, regardless of the actual screen resolution (this makes it convenient to compare devices with different screens).
|40 fps||22 fps|
|27 fps||16 fps|
|58 fps||37 fps|
|75 fps||48 fps|
|48 fps||31 fps|
|63 fps||40 fps|
|56 fps||36 fps|
|59 fps||49 fps|
|100 fps||63 fps|
|60 fps||59 fps|
|157 fps||97 fps|
As you remember, when testing the iPhone 11, we found a lot of oddities in the GFX Benchmark results. Here everything is exactly as it should be. The difference is about one and a half times, and in almost all tests!
The next test is 3DMark. All results are in points.
Not everything went smoothly with 3DMark. Sling Shot didn’t work on both smartphones, API Overhead stuck on XS Max, but at least the comparison in Sling Shot Extreme was successful. And the picture turned out to be very flattering for a novelty.
Finally. Basemark Metal. And here we see a completely similar picture.
|3463 points||2162 points|
Based on the results of all tests, we can conclude that Apple has provided a stable performance gain, which is evident in all benchmarks. Not everywhere it is huge. in most cases we can talk about about 20 percent superiority of the new product in terms of CPU and 40 percent in terms of GPU, but this is a good result. We cannot say that we are amazed, but yes, everything is as it should be in the new generation of iPhone.
Review of the flagship smartphone Apple iPhone 11 Pro Max
The iPhone 11 Pro Max has a 6.5 ″ OLED screen with a resolution of 2436 × 1125, which gives a decent 458 ppi pixel density. Same options as iPhone XS Max. However, we decided to test the display of the novelty to the fullest extent of our methodology. Alexey Kudryavtsev, editor of the “Monitors” and “Projectors and TV” sections, got down to business.
The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are slightly better than that of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the turned off screens (on the left. Nexus 7, on the right. Apple iPhone 11 Pro Max, then they can be distinguished by their size):
The screen of the Apple iPhone 11 Pro Max is slightly darker (brightness in photographs is 107 versus 111 for the Nexus 7). The doubling of reflected objects in the screen of the Apple iPhone 11 Pro Max is very weak, which indicates that there is no air gap between the layers of the screen (more specifically, between the outer glass and the surface of the matrix). Due to the smaller number of boundaries (such as glass / air) with very different refractive indices, such screens look better in conditions of intense ambient light, but their repair in case of cracked outer glass is much more expensive, since the entire screen has to be changed. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating (effective, better than that of the Nexus 7), so fingerprints are much easier to remove, and appear at a slower speed than in the case of ordinary glass.
With manual brightness control and when displaying a white field in full screen, the maximum long-term brightness value was about 750 cd / m2 (up to 800 cd / m2 in normal mode and up to 1200 cd / m2 in HDR mode), the minimum. 1.9 cd / m2 m². The maximum brightness is very high and, given the excellent anti-glare properties, readability even on a sunny day outdoors will be good. In complete darkness, the brightness can be lowered to a comfortable value. In the presence of automatic brightness control according to the light sensor (it is located above the slot of the front speaker), which is enabled by default. In automatic mode, when the ambient light conditions change, the screen brightness both increases and decreases. The operation of this function depends on the position of the brightness adjustment slider: with it, the user sets the desired brightness level for the current conditions. If nothing is changed, then in complete darkness, the brightness drops to 1.9 cd / m2 (very dark), in an office illuminated with artificial light (about 550 lx), the screen brightness is set to 100-115 cd / m2 (acceptable), in very in bright surroundings (corresponds to illumination on a clear day outdoors, but without direct sunlight. 20,000 lux or a little more) rises to 750 cd / m² (up to the maximum, which is necessary). The result did not quite suit us, so first in the dark, and then in the office, we slightly moved the brightness slider up (in the quick access menu), and for the three conditions indicated above, we got 13, 130 and 750 cd / m² (ideal). It turns out that the automatic brightness control function works adequately, and it is possible to adjust the nature of the brightness change to the user’s requirements. At any brightness level, modulation is present with a frequency of about 240 Hz. The figure below shows the dependence of brightness (vertical axis) on time (horizontal axis) for several brightness settings (approximate values):
It can be seen that at maximum and average brightness, the modulation amplitude is not very large, as a result, there is no visible flicker. However, with a strong decrease in brightness, modulation appears with a large relative amplitude, its presence can already be seen in the test for the presence of a stroboscopic effect or simply with rapid eye movement. Depending on individual sensitivity, such flickering can cause increased fatigue. However, the modulation phase differs across the screen area, so the negative effect of flickering is reduced.
This screen uses a Super AMOLED matrix. an active matrix on organic light-emitting diodes. A full-color image is created using subpixels of three colors. red (R), green (G) and blue (B), but there are half the red and blue subpixels, which can be referred to as RGBG. This is confirmed by a fragment of a micrograph:
For comparison, you can see the gallery of micrographs of screens used in mobile technology.
In the fragment above, you can count 4 green subpixels, 2 red (4 halves) and 2 blue (1 whole and 4 quarters), while repeating these fragments, you can lay out the entire screen without gaps and overlaps. For such matrices, Samsung has introduced the name PenTile RGBG. The manufacturer considers the screen resolution for green subpixels, for the other two it will be two times lower.
The screen has excellent viewing angles. True, when deviated even at small angles, the white color acquires a slight bluish tint, but the black color remains simply black at any angle. It is so black that the contrast setting is not applicable in this case. For comparison, we present photographs in which the screens of the Apple iPhone 11 Pro Max and the second participant of the comparison show the same images, while the brightness of the screens was initially set to about 200 cd / m2, and the color balance on the camera was forced to 6500 K.
Note the good uniformity of brightness and color tone of the white field.
The color balance is slightly different, the color saturation is normal. Recall that a photograph cannot serve as a reliable source of information about the quality of color rendition and is provided only for a conditional visual illustration. In particular, the pronounced reddish tint of white and gray fields present in the photographs of the screen of the Apple iPhone 11 Pro Max is visually absent when viewed from a perpendicular view, which is confirmed by hardware tests using a spectrophotometer. The reason is that the spectral sensitivity of the camera matrix does not exactly match this characteristic of human vision.
Now at an angle of approximately 45 degrees to the plane and to the side of the screen. White box:
The brightness at an angle on both screens has noticeably decreased (to avoid strong darkening, the shutter speed is increased compared to previous photos), but in the case of the Apple iPhone 11 Pro Max, the drop in brightness is much less pronounced. As a result, with formally the same brightness, the screen of the Apple iPhone 11 Pro Max visually looks much brighter (in comparison with LCD screens), since you often have to look at the screen of a mobile device at least from a slight angle.
It can be seen that the colors have not changed much on both screens and the brightness of the Apple iPhone 11 Pro Max smartphone is noticeably higher at an angle. The switching of the state of the matrix elements is performed almost instantly, but at the turn-on front there may be a step with a width of about 17 ms (which corresponds to a screen refresh rate of 60 Hz). For example, this is how the dependence of brightness on time looks like when switching from black to white and vice versa:
In some conditions, the presence of such a step can lead to plumes trailing behind moving objects. However, dynamic scenes in films on OLED screens are distinguished by high definition and even some “jerky” movements.
The gamma curve, plotted using 32 points at equal intervals in terms of the numerical value of the shade of gray, did not reveal a blockage in either the highlights or the shadows. The exponent of the approximating power function is 2.20, which is equal to the standard value of 2.2. At the same time, the real gamma curve deviates very little from the power dependence:
Such spectra are typical for OLEDs. the components are well separated, which allows achieving a wide color gamut. However, in this case, the gamut is neatly adjusted to the sRGB borders. As a result, visually the colors have natural saturation.
This applies to images that have an sRGB profile or no profile at all. However, native to modern top-end Apple devices is the Display P3 color space with slightly richer greens and reds. Display P3 is based on SMPTE DCI-P3 but has a D65 white point and a gamma curve of approximately 2.2. In addition, the manufacturer claims that since iOS 9.3 color management is supported at the system level, which makes it easier for iOS applications to correctly display images with a prescribed color profile. Indeed, adding the Display P3 profile to the test images (JPG and PNG files), we got a wider color gamut than sRGB (output in Safari):
Note that the coordinates of the primary colors almost exactly coincided with those prescribed for the DCI-P3 standard. Let’s look at the spectra in the case of test images with the Display P3 profile:
It can be seen that in this case there is a slight cross-mixing of components in the red area, that is, the color space native to the Apple iPhone 11 Pro Max screen is slightly wider than Display P3.
The grayscale balance is very good, as the color temperature is close to the standard 6500 K, and the deviation from Spectra of absolute black body (ΔE) is less than 10, which is considered acceptable for a consumer device. At the same time, the color temperature and ΔE vary little from shade to shade. this has a positive effect on the visual assessment of the color balance. (The darkest areas of the gray scale can be ignored, since the color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)
This Apple device has a Night Shift function that makes the picture warmer at night (how much warmer. the user indicates). For a description of why this might be useful, see the iPad Pro 9.7 ″ article. In any case, when having fun with a tablet or smartphone at night, it is better to lower the screen brightness to a minimum, but still comfortable level, and there is no point in turning the screen yellow with the Night Shift setting.
There is a True Tone function, which, if enabled, adjusts the color balance to the environmental conditions.
For example, we activated it and placed the tablet under LED lights with cool white light, resulting in values of 2.1 for ΔE and 6800 K for color temperature. Under a halogen incandescent lamp (warm light). 3.2 and 4900 K, respectively, that is, the color temperature has become lower. The function works as expected. Note that the current standard is to calibrate display devices to a white point of 6500 K, but in principle, correction for the color temperature of external light can be useful if you want to achieve a better match of the image on the screen with what is seen on paper (or on any medium. on which colors are formed by the reflection of incident light) in the current conditions.
According to the criterion for outputting frames, the quality of video playback on the screen of the device itself is very good, since frames (or groups of frames) can be output with a more or less uniform alternation of intervals and without frame drops up to 4K files and 60 fps. When playing video files with a resolution of 1920 by 1080 (1080p) on a smartphone screen, the image of the video file itself is displayed exactly at the height of the screen (in landscape orientation). The clarity of the picture is high, but not perfect, since there is no escape from interpolation to the screen resolution. The brightness range displayed on the screen corresponds to the actual for this video file, except that in the shadows a couple of shades merge with black. Note that this smartphone has support for hardware decoding of H.265 files with a color depth of 10 bits per color, while displaying gradients on the screen is carried out with much better quality than in the case of 8-bit files. Display of HDR files is also supported: colors are saturated, the number of gradations is not reduced.
Let’s summarize. The screen has a very high maximum brightness and has excellent anti-reflective properties, so the device can be used outdoors without any problems, even on a sunny summer day. In complete darkness, the brightness can be lowered to a comfortable value. It is permissible to use the mode with automatic brightness adjustment, which works adequately. The advantages of the screen also include an effective oleophobic coating, support for sRGB color gamut (with the participation of the OS) and a very good color balance. At the same time, let’s recall the general advantages of OLED screens: true black color (if nothing is reflected in the screen), noticeably less than that of an LCD, the drop in image brightness when viewed from an angle. The disadvantages include the modulation of the screen brightness, which appears at low brightness. Users who are particularly sensitive to flicker may experience increased fatigue due to this. However, the overall screen quality is very high.
