Method to remove junk from apps on iPhone

Some applications have a specialized function that allows you to clean everything at once in the settings. With its help, you can clear the memory of the gadget without uninstalling the program itself. You can activate the option like this:

  • open the “Settings” of a particular utility;
  • find “Clear cache”.

In multimedia players there is an excellent opportunity to eliminate unnecessary information directly from the desktop interface.

What is memory cleaning for??

Not necessarily freezing and slow execution of commands is a sign of technical problems, most often the reason is a banal cache overflow. The longer the phone operates, the more unnecessary “junk” accumulates in the memory. If you do not clear it in time, then the space will gradually fill up, the number of free gigabytes will decrease. You can easily clear the cache on your own.

Naturally, the fast loading of pages cannot but rejoice, only constant filling leads to a reduction in free space. Over time, the operating system ceases to cope with volumes and cannot function as quickly as before.

Many users of iPhones and other devices, including Androids, try to completely clear the cache. In fact, experts do not advise doing this too often, because in some cases it can help significantly, will allow you to quickly get to some pages of different sites, or even just cope with the tasks set by the user.

If the memory on the iPhone is shrinking at a terrible speed, for the reason that the smartphone has not been cleared of unnecessary for a long time, it is necessary to immediately solve this problem, because otherwise you will not be able to save even some multimedia files to the phone.

The OS storage is filled with caching objects for various applications used on the iPhone. iOS immediately saves information about the processes that took place on the device, this includes downloads, updates, and more. So the more software you have installed, the more often the iPhone will be used, the higher the number of cached files stored in memory will be. Memory is loading. the speed of work decreases.
