Although we have gone through the above two steps, we can see that our space has only returned to a small part (especially when we don't want to delete Tencent folders). If we don't want the phone to run out of memory again in a few days, we should either do it again or clear all the data stored in the phone at once.

Secondly:

When a mobile phone is used for a long time, it will produce a lot of caches, some of which cannot disappear automatically. After a long time, it will form a lot of garbage; Too many software installations will also occupy memory. The mobile phone is out of memory, so it can only be cleared and released. The method is as follows:

1, clear the memory. Download and install mobile phone management software, such as cheetah cleaner, 9 1 mobile assistant, etc., to further clean up the cache, system and uninstall residues.

2. Software management. There are too many installed software, so it is necessary to uninstall and clean up the infrequently used software to free up memory. For the software that takes up too much memory, you can release the memory space through 9 1 Mobile Assistant and Cheetah Cleanup Master "Move the corresponding software to SD card".

3. System settings. Install the SD card automatically when installing the software, enter the settings and select "Save". When entering storage, you can also see memory information and memory card information. Just choose to download the "default storage location" and change it to SD card.

Of course: if you reset the phone-restore the factory settings, the cleaning will be more thorough (provided that the phone must be backed up)
