1. You can manually delete a lot of system garbage, such as unnecessary residual files and empty folders.

2. After finding the corresponding location, you can delete small and much garbage such as cache files.

3. If you are afraid of deleting mistakes, you can achieve the same goal with cleaning software. I recommend you to use Tencent mobile phone housekeeper, which has the functions of garbage cleaning, file cache cleaning and residual files, and is equally effective.

You can do the following:

Both computers and mobile phones download and install PP assistants, and official website has corresponding versions.

2. Connect the data cable to the computer, select "Trust", and the PP assistant is connected successfully. You can see the details of the mobile phone.

3. Click "Garbage Cleaning" in the toolbar on the left to "slim down" the mobile phone. Is it convenient? After the garbage is cleared, the use of mobile phones will be smoother.
