The reason why the memory of Apple's mobile phone is getting smaller and smaller is basically that there are more and more software installed on the mobile phone, and each software will generate a cache. If it is not cleaned for a long time, it will become more and more and take up a lot of space. We can see which software on the mobile phone takes up more memory space. You can clean them up, turn on the phone's setup function and select "General".

After entering general use, select "storage space and iCloud usage".

After entering the storage space and iCloud usage, select Manage Storage Space.

After entering the storage space management, you can see the software that occupies a large memory space of the mobile phone, or you can look at the software that is not commonly used.

Unused software can be uninstalled directly. If it is commonly used software, the reason for the increase is that a large number of caches are generated, which can be cleaned up. The basic software steps to clean up the cache are all cleaned up in the settings. Taking the commonly used prestige cache cleaning as an example, this paper introduces the steps of cleaning the software cache, enters the personal center and clicks "Settings".

After entering the settings, click "General" to set general functions.

After entering GM, click "storage space" below to clear the cache.
