1. Problem description
The current system version is: 15.4.1, after upgrading the previous version, found that the memory space suddenly less than 6G or so, to the Internet search, many people have been recruited, it seems that the lucky one is not only one of me!
This is the optimized image:
Note the occupancy of System Data
The occupation of "system data" before optimization is 18G, and after optimization, it occupies about 8G, freeing up 10G of space.
2. Solution
Note: The solution needs to restart the phone, iPhone if the space is occupied after the shutdown will not be able to turn on (commonly known as the brick machine), which is also the most pit place of the iPhone, please ensure that the iPhone reserves more than 4G space before restarting, you can uninstall the app that occupies a large space (recommended non-chat software, otherwise the chat history will be emptied), and then reinstall it.
This tutorial takes the iPhone xs max without the Home button as an example, and will explain other special cases.
2.1. Use the Home key to clear the cache
Step 1: Turn on the Touch button
The purpose uses the virtual Home button.
Access path:<设置> -> <辅助功能> -> <触控> -> Open Assistive Touch
Step 2: Enter the shutdown interface
Access path:<设置> -> <通用> -> shutdown
As follows:
Shut down the entrance
Shutdown interface
Step 3: Long press the Home button to clear the cache
After long pressing the Home button, the screen will flash into the password input interface, at this time the cache cleaning is successful, and it needs to be restarted before it can take effect.
Step 4: Restart your phone
After the restart is completed, if you look at the storage space usage, you will find that the use of system data has been greatly reduced!
Mobile phone long-term use will have this cache occupation of the situation, should be a software design defect, why so pit, I do not know, hahaha, can only be operated once in a while!
See the comment area has a friend said that this method does not work, the article only applies to the system data items take up a lot of space problems. For the memory occupation of the documents and data in the app is invalid, this is another pit, in order not to oversize the article, I am ready to start another article: Spit it out: the document and data memory of the app in ios
