How to test an iPhone before hand-buying

First you need to identify the gadget externally

test, iphone

At this point, I see no reason to talk about possible bruises, scuffs and chips on the front or rear panels. This is on the surface, and whether to put up with them or not. everyone decides for himself. However, serious damage is a sign of a careless attitude that does not lead to anything good. For example, if the angle of the case is obviously flattened, this suggests that the device was falling. apart from external damage, this could also lead to internal damage, which can show itself over time. A microcrack may form on the motherboard, which will increase over time.

  • iPhone 5s and iPhone SE: the latter has a [SE] badge on the bottom of the back panel. just below the “iPhone” sign;
  • iPhone 6 (Plus) and iPhone 6s (Plus): the latter has an [S] icon on the bottom of the back panel. just below the “iPhone” sign;
  • iPhone 7 (Plus) and iPhone 8 (Plus): the former has a metal back panel, while the latter is made of glass for wireless charging;
  • iPhone X and iPhone XS: the latter can be recognized by the number of holes for the spoken microphone to the left of the Lightning port. it has only three of them instead of six in its predecessor;
  • iPhone 8 and iPhone SE 2020: the Apple logo on the back of the latter is in the center. in the former it is closer to the top edge.

It’s easier with the iPad. there is a model number on the back of Apple tablets, which you can type into a search engine and immediately see the name of the gadget in front of you. Model numbers usually start with the letter “A” and consist of four digits. in this regard, iPads are very similar to MacBooks and other Apple computers.

This gadget was drowning or did not even have time to get wet

Unfortunately, the iPad does not have an obvious indicator that determines the ingress of moisture into the case, but Apple smartphones have one. In the iPhone 5 and above, it is located in the SIM card tray. previously, Apple engineers installed two at once: in the charging port and 3.5 mm audio output. You need to look inside: if a red dot is clearly visible there, then there was water inside. if not, it did not get there. This must be done even with models that are protected from moisture according to IP67 or IP68 standards, since over time, special gaskets that provide it lose their effectiveness.

By the way, this is especially important with iPhone models that are protected from moisture. When such people first appeared, users, with joy, began to dive with them, take pictures under water and simply take smartphones with them into the bathtub to “swim” and watch TV shows. Today hysteria about moisture protection is not so widespread, but drowned people still appear. They are often reanimated and even start working. However, it is important to understand that corrosion can still take its toll, so after a few months there is a chance to actually end up with a brick that will not be suitable for repair.

How to check iPhone by serial number on Apple website

often than not, an external assessment is more than sufficient to determine the appropriateness of further verification of the device. Nevertheless, it protects from the fact that you run into a wild fake not 100%. For example, in a case that is very similar to the new iPhone SE 2020, there may be the most ordinary iPhone 8 from the distant past. Find out the model name through the “Settings” menu “General” “About this device”. here you need to pay attention to the items “Model name”, as well as “Memory capacity” with an exact indication of the size of the drive, which is also used in attempts to deceive the buyer.

On the official Apple website, it will be possible to check the mobile device by the serial number. you can take it from the item of the same name in the same menu “Settings” “General” “About this device”. A set of letters and numbers must be entered in the “Enter serial number” field, then indicate the verification code in the “Enter code” field and click on the “Continue” button. After that, an indication of the model of the gadget you are dealing with will immediately appear on the page. over, there will also be information about the official warranty for the device, which may not end yet, as well as about the right to free maintenance.

It’s better not to mess with those locked under the operator

In some countries, Apple smartphones are sold together with a service contract with a specific operator. for example, in the United States, from which these gadgets are actively transported due to the minimal cost. In this case, the iPhone is locked for use with a certain service provider, and it will be officially possible to untie the device from it only after the expiration of the contract or payment of a penalty to the operator. It is best to avoid such gadgets. to make sure your device is not locked, you need to insert a local SIM card into it. If the device has found a network, you can safely continue checking.

It will not hurt to open any site via the Internet

This can be done both using the mobile Internet and via Wi-Fi. This will help ensure that the communication modules are working fine. What’s more, it’s a great excuse to test cellular connectivity on your iPad if it needs to support it. The fact is that Apple tablets are sometimes hacked in order to untie the Apple ID. In this case, the cellular communication module usually falls off, so the tablet with its support turns into a version with only Wi-Fi. I would not say that this is a critical procedure in itself, but an iPad with LTE support and without it costs different money.

I propose to abandon non-original screens

It’s time to assess the condition of the iPhone or iPad screen. I recommend examining it for dead pixels, looking at pictures of different colors: if some points show the shade incorrectly, there is reason to think. over, look at the shade of the device menu on a white background. If it frankly turns yellow or, conversely, goes into an unnaturally cold tone, it is highly likely that you have a gadget with an unoriginal screen of low quality in front of you. These replace the original ones when they do not survive falls. I recommend refusing to buy something like this.

It’s important to try setting up Touch ID and Face ID

During the check, I also recommend trying to configure the Touch ID fingerprint sensor or Face ID face scanner. this can be done using the Settings menu “Touch ID and passcode” or “Face ID and passcode”, respectively. If you manage to activate the protection, and it works during unlocking, you can move on. It is very important to validate biometric authentication sensors on Apple mobile devices because they cannot be replaced. They are tied to the motherboard they come with and may not work either after severe physical damage or after a failed repair.

Checking iPhone before buying from “gray dealers”

Take care of the SIM card to check the iPhone. If you do not have a micro SIM (for iPhone 4S) or nano SIM (for iPhone 5), then you will not be able to check your phone for the ability to make calls.

As a rule, the cheapest devices are phones from the showcase or replaced by previous customers. To find out if the iPhone has been replaced, you need to check the iPhone by IMEI (links at the end of the review). Examine the box carefully to ensure that the protective films are in place without air bubbles underneath.

Buying an iPhone from a “gray” supplier can save 5. 20 percent of the cost of the device at official points of sale. Usually “gray” smartphones enter the Russian market from Europe and Asia. However, there is some chance that the iPhone was already in use.

The first sign that the device has already been used is that it does not need to be activated. At the same time, the activation request does not mean at all that the iPhone is new. The fact is that the activation procedure must be repeated every time after installing a new firmware. That is, this method is not 100% effective.

But you can still check the iPhone by serial number. For this you need:

  • Go to Apple’s website under Check Service and Support Eligibility.
  • Enter the serial number of the iPhone in the appropriate field (you can find it in the activation menu by pressing the “i” key on the right side of the window or in Settings. General. About this device)
  • Press the Continue key.

If the smartphone is new or officially restored, a message like “You need to activate the iPhone” will be displayed in a new window.

If the device has been activated, then in the Right to Service and Support section, the warranty expiration date (356 days from the date of activation) will be entered.

A one-year warranty is proof that your iPhone is new.

Before buying, you need to determine from which country the iPhone is, and whether it is locked to the operator.

Here’s what you need to know about your new phone:

  • The country from which it was imported iPhone.
  • Correspondence of what is in the number printed on the box with what is inside the box.
  • Well, and the option when it is impossible to determine the detachment of the device from the operator by the model. Check iPhone by IMEI.

12 Things MUST Check Before Buying Used iPhone (2020)

The basic data of the phone can be found without opening the package. On the back of the box there will be a sticker with barcodes with iPhone data.

The same information can be obtained by turning on the phone and launching the Settings application. In the menu “General” “About device”.

Check if the numbers shown on the box and in the phone settings match. If not, then it is likely that this device has been in a warranty workshop.

If the serial number starts with 5K, then it is a factory refurbished unit.

How to check iPhone for authenticity

Almost half of iPhone owners in our country bought their phones from “gray” dealers. That is, the devices were brought from the USA, Europe and Asia by private individuals. And while the trend continues. This article is for those who buy a phone from similar sellers and those who buy used smartphones from their hands. If you are not sure that you have an iPhone in front of you, then here is an article on how to distinguish a fake iPhone from an original Apple smartphone.

In some countries, iPhones are sold locked under a specific operator. This limits their use in other countries and requires unlock, which is not always possible. In addition, every time after a new firmware is released, you have to wait for the unlock release. There is an opportunity to use the services of unlocking phones (there should be an advertisement for intermediaries), but this is additional money. from 80 and above. And the result is not always guaranteed. Better and safer to check the iPhone for originality when buying.

Note to the hostess. Apple products are guaranteed worldwide. However, this does not apply to iPhones due to restrictions on the use of phones by various cellular operators.

1 Check iPhone by Model

By the model number, you can find out from which country this iPhone was brought.

Letters after the numbers before the “/” sign indicate the region of sale and warranty service.

For example MC131 TA / A. iPhone 3G 16Gb Black phone purchased in Taiwan (Chunghwa Telecom).

Official Russian telephones (PCT) have the following numbers: MB489RS / A, MB496RS / A, MB500RS / A, MC131RS / A, MC132RS / A, MC133RS / A, MC134RS / A.

Green. good (unlocked).

Phones with indices TA (Taiwan), ZA (Singapore), ZP (Hong Kong) are guaranteed to work in our networks.

Taking into account the lowest prices, most of the “gray” devices are imported from there.

Contact with moisture

Drowned smartphones are often found in the secondary market. Hence, the iPhone was being repaired. Naturally, further use does not bode well and such a gadget will not last long. Apple has made sure that anyone can understand whether the device has come into contact with water. this applies to absolutely all models. In “apple” devices there is a special indicator of contact with liquid.

Fraudsters often take advantage of the fact that experienced users do not know about it, so it is easy to deceive such “simpletons”. But how can this be determined? It’s very simple. just open the SIM card slot (on models 5 and above) and illuminate the place with a flashlight. If the visible line is white or silver, then everything is in order. If it is clearly colored red, then contact with moisture took place.

We check originality by IMEI

The first thing you need to make sure is whether the device is real in front of you, and whether it matches the description in the ad.

For the convenience of checking for originality, Apple has introduced an option that assigns each iPhone a unique set of letters and numbers. This combination is the serial number, called IMEI. It can be recognized on the box, in the SIM card slot, on the back of the case (only applies to old models from 5 to 6S) and in the device itself (this is the item that can fully provide the real IMEI, we’ll tell you why below). How to find out the “serial” through the settings:

  • In the “Settings” go to the “General” item;
  • Then select the “About device” tab;
  • In the list that appears, find the line “Serial number”.

After receiving the serial number, go to the official verification website This will make sure that in front of you is really the model and color of the device that you wanted. If the gadget is officially purchased, then the date of purchase will be confirmed, which also indicates that the smartphone is completely original, thereby, this will make sure of the seller’s words.

Do not forget to also break through the “serial” on the theft databases, for example, on the site We also have a separate article on how to check iPhone for originality, so we advise you to read it.

How to check iPhone when buying hand-held

However, the buyer may be offered a stolen or lost gadget, and a relative or “confidant” may come to a personal meeting. Therefore, it is not enough to know the intricacies of checking the smartphone itself (even if at first glance it seems that everything is perfect), you need to carefully look at the seller’s behavior. And also. unscrupulous traders can pass off the old model as a new one, taking advantage of the fact that most people are ignorant in this matter. How not to fall for the tricks of scammers and become a happy owner of Apple products is described in detail in this article.

Opened or not?

The only way to “get” into the device is to unscrew the two star-shaped bolts located near the Lightning charging connector and speakers. The screws must be firmly screwed in and must not fall out, must not be damaged, and the case near them must not be scratched. If there is at least one sign of an autopsy, then the repair has taken place, and, most likely, somewhere in an underground workshop. professional equipment is used in a high-quality service center.

Why do I need iPhone verification?

Used gadgets can be found for half the market price! Especially if the former owner was a neat person. it will be almost impossible to visually distinguish a smartphone “out of the box” or a little worn “out of hand”.

Why not blindly believe the seller’s beautiful words? Let’s look at several reasons:

  • To take possession of the original gadget;
  • Use a working smartphone that won’t break in a couple of days;
  • Don’t overpay for a cheap replica;
  • Do not give fabulous sums for a device completely replaced by Chinese parts;
  • Not paying for a model that is actually lower than the one stated (for example, mistakenly purchase X instead of XS).

And this is not a complete list of reasons why it is worth checking the device thoroughly. Actually, now we turn to the procedure for checking our smartphone.

Check if Find My or Find My iPhone is turned off

Another sign that the smartphone has been stolen or found somewhere.

  • Launch “Settings” and click on the name of the previous owner in the account;
  • Find “Find My” or “Find My iPhone” in the list (depending on the model. on gadgets that support a newer version of iOS, “Find My” will be written);
  • If the function is disabled, move the toggle switch to the right and ask the owner to enter the password. Naturally, the seller must know him. If he behaves strangely and refuses to do it, then this is a reason to think.

Then disable the function. It is worth making sure of this, otherwise the fraudster can block the iPhone from a distance and demand money from above for unlocking after the money has been transferred.

How to check a used iPhone before buying it.

Battery wear

The battery health check was first introduced in iOS 11.3. Previously, you had to install third-party applications to check battery wear. To find out how much the battery is worn out, just go to “Settings”, then “Battery” and select “Battery status”. The rate ranges between 80-90%. If the level is lower, then this is a reason to refuse to purchase, because the phone is clearly outdated or completely mercilessly used by the owner.

Camera check

This is worth noting as a separate item, because most future iPhone owners deliberately do not check or simply forget to do it.

First, check out the appearance of the rear camera. The peephole should be level, and if it dangles or stands crooked, then the module has been changed. There should be a lot of dust inside both chambers. It can also signal that this part has been disassembled with careless hands.

Next, launch the front and rear cameras, take some pictures. In the gallery, check that there are no stripes or dots in the pictures. Check the HDR and flash function. everything should work clearly.

How to check if you bought a new iPhone? Method 1

Apple has a Service and Support Eligibility section on Apple’s website that lets you quickly and effortlessly verify that the iPhone you’re buying hasn’t actually been used before. All the user needs to know to work with the service is the serial number of the device. For activated gadgets, this number can be found in the “Settings”, in the “General” section, the menu item “About this device”. In the event that the smartphone meets the user with a start-up welcome screen, his serial code can be found by pressing the “i” button in the lower right corner.

So, to check your iPhone, follow these steps:

one. Go to the Check Service and Support Eligibility section of the Apple website.

2. Enter in the appropriate field the serial number of the iPhone (how to find the serial number), enter the code shown in the picture and click Continue.

IPhone serial number NEVER contains the letter “O” (uses the number “0” (zero).

3. If, when checking a supposedly new iPhone (or an officially restored (ref, refurbished) Apple), the message “Activate your device” appears, then this really confirms that the smartphone had no history and is indeed new.

After activation, the Right to Service and Support service will display (perhaps not immediately, but within 24 hours) the estimated expiration date of the Right to Service and Repair, which is determined by adding 365 days to the activation day. In other words, to find out the date of the first activation, subtract exactly 1 year from the calculated date.

NOTE: The data on the Apple server may not change immediately, it usually happens in the interval from 1 minute to 12 hours.

How to check if you bought a new iPhone (activated or not)?

You have been sold an iPhone in a sealed box and the seller assures that it is new. Before you can start using your new Apple smartphone, you need to activate it. The activation procedure involves connecting a smartphone with an inserted SIM card to Apple’s activation servers. To do this, you just need to connect to Wi-Fi or use cellular data.

And only after the iPhone owner receives confirmation of activation, he will be able to use his device.

Thus, if, when the smartphone is turned on for the first time, the user immediately goes to the home screen, bypassing the welcome, activation and settings screens, then it has already been in use. At the same time, if after the first start-up of the iPhone, the welcome screen appeared. this does not mean that the gadget was not used. The fact is that a screen with the word “Hello” in different languages โ€‹โ€‹of the world appears every time the iPhone is reset to factory settings or after the iOS restore procedure on the computer. In other words, even unpacking the sealed box and the appearance of the welcome screen when you turn on the purchased iPhone does not guarantee that the smartphone is new.

How to check if you bought a new iPhone? Method 2

Open the Settings app and follow the path: General โ†’ About this device.

In the window that appears, open the “Limited Warranty”.

The estimated expiration date of the Right to Service and Repair, which is determined by adding 365 days to the activation day, will appear here (perhaps not immediately, but within 24 hours). In other words, to find out the date of the first activation, subtract exactly 1 year from the calculated date.

If the activation date that you carried out differs from the one specified in the service “Checking the eligibility for service and support”, then you can safely file a claim with the seller. the smartphone was activated earlier, ie. unfortunately, you are not the first owner of this iPhone.

Let’s take a real life example. In the post-Soviet space, it is often used to sell gray (illegally imported) activated iPhones under the guise of new ones. How does this happen? New locked (tied to a mobile operator) iPhones are sold, for example, in the United States, at a fairly low price. They are bought by “businessmen” for the purpose of subsequent unlocking (decoupling from the operator) for a fee.

However, often in order to unlock such an iPhone, in most cases, its box must be unpacked, software restored and repacked. By and large, this is a new phone (in fact, it was not used), identical to the one purchased from an official reseller, however, the date of its first activation will not correspond to the date of activation by the buyer, since it has already been produced earlier. Naturally, the service and support period of such a phone will be less than a year.
