How does Apple's mobile phone delete garbage such as insufficient memory?

Hello, I'm glad to answer your question.

The reason is that mobile phone photos only take up a part of memory, and other applications on the mobile phone still take up a lot of memory, resulting in insufficient memory of the mobile phone.

Solution 1: directly delete the application on the mobile phone and then download and install it again, so that the cache and manuscript data in the mobile phone application are gone, and the memory is freed up.

Solution 2: clear the application cache and manuscript data on the mobile phone one by one, taking WeChat as an example:

1. Open WeChat and find the Settings button.

2. Open the settings and find the general bar.

3. Open GM, find and empty the storage space of WeChat, and click to empty the cached data.

I hope I can help you.
