1. First, turn on the settings button in your phone.

2. Then click the General button in the settings.

3. Then open the iPhone storage space option.

At this time, you can see all the programs installed in your mobile phone.

5. You can choose the glory of the king to uninstall before downloading.

6. If there are no applications that need to be uninstalled, you can also clean up useless files or other things contained in applications that take up a lot of memory. For example, empty the space in WeChat. Open wechat and select "I" > >; "Settings" > >; "general" > >; "Storage space", select "Clean up WeChat".

Start releasing the storage space of the mobile phone:

1, the memory is the largest at first, so it can reach the maximum memory in the current state of the mobile phone when it is turned on again.

2. Using software to release memory directly can release some memory, but it is very limited.

3. If the memory is small after starting the machine, you need to optimize the machine. There are several optimization methods:

1) If your machine is too messy, you'd better format your machine to keep the cleanest system. You can also see what your maximum memory is at this time.

2) Install as little software as possible, start it up automatically, and have permanent memory, such as call sticker, firewall, enhanced situational mode, automatic keyboard lock, etc.

3) Try not to install other font files. Font files will also be loaded into memory when they are turned on, and the font capacity is relatively large, which will lose a lot of memory at once.

Optimize memory advanced:

1, some software can manually end threads (processes) to release memory. Depending on the system and software. There are two kinds of threads, one comes with the mobile phone and the other is installed later. All non-mobile phones can be turned off.

2. If you don't know the function of the mobile phone's own program, you'd better not turn it off casually. After the phone is turned off, some functions of the phone may not be available or the phone will be restarted, because the programs that come with the system will run even if it is turned off and started next time, so it is generally only used when there are special needs.

3. Enter flight mode (flight mode or offline mode), so as to close communication-related threads to gain more system memory. This is only used when there are special needs, such as playing a game that requires very high system memory.
