When the WeChat application is deleted, WeChat will also disappear from the mobile phone, and the "documents and data" it occupied before will also be released. If you can, you can delete the reloaded WeChat regularly to reduce its occupied space.
Of course, deleting and reinstalling WeChat may not be suitable for everyone, because some friends may have a lot of important chat information in WeChat. If this is the case, we can also reduce the space occupied by WeChat on the iPhone through the cleaning function provided by WeChat itself. In the "I" column of WeChat, click the "Settings" column.
In the settings, click the General column.
In the general list, click the column "Clean up the storage space of WeChat".
Then wait for WeChat to automatically clean up some temporary files, and a cleaning report will be generated after completion. If you still want to manually clean up, you can also click the "View WeChat Storage Space" button.
Then you can manually select some chat conversations, delete some pictures in the conversations, and release more storage space.
