Open Settings → General → Use → Manage Storage Space in turn on the main screen of the mobile phone.
Enter the detailed list of storage space, and arrange it according to the memory capacity occupied by each software application from large to small. According to our own situation, we can choose some software applications that are not commonly used and then occupy special capacity, and click Open.
At this time, enter the detailed page of an infrequently used application software, and click the delete application software button below.
Second, delete the mobile QQ cache file.
Of course, we usually use WeChat and QQ because we often use or receive various audio or facial words in chat, so there is no way to delete the cache directly in the settings. We need to log in to QQ on our mobile phone, and then open Settings → Chat Records → Clean up the cached data (here, only clean up the cached files, such as chat faces, but not the text content of the chat).
Third, delete the WeChat cache file.
The next step is to clean up the cache files on WeChat, log in to WeChat on your mobile phone, and open Settings → General → Clean up the storage space of WeChat in turn.

Wechat will directly enter the process of cleaning up storage space. After cleaning up, it will show how many temporary files have been cleaned up, which does not include audio, small video and text in chat. If you want to make more room,
You can click the View WeChat Storage Space button to further clean up the audio, video and text, and you can delete one or several of them according to your own choice.

However, in addition to cleaning the cache on the mobile phone, we can also install other third-party application software assistants on the computer and then use the garbage cleaning tools inside to deal with it, but this method is not as good as cleaning the cache on the mobile phone manually.
Clean up the world more thoroughly and look at your own needs; Also, if there are too many photos and videos on the mobile phone, it is also recommended to transfer them to the computer, which takes up the most space.
