When the storage space of the iPhone is full, is this slimming method feasible: Backup the iPhone to iTunes-> Factory reset the iPhone-> Restore from the previous backup

I have only done this when migrating data from the old phone to a newly bought iPhone, and I can see that the used space of the new iPhone is far less than the used space of the old iPhone.

Anonymous472 May 6, 2025Yes, many apps have a lot of caches, and those that are not commonly used can be uninstalled and retained to save a little space

Anonymous6003 May 6, 2025Other storage space occupies a lot, so you can use backup to restore it. If it doesn't take up much, it doesn't free up much space

Anonymous13183 May 6, 2025Because the replacement migration only touches paths such as Documents in the sandbox, while many other paths are not migrated That's why the new iPhone you mentioned above uses less space However, the reason why those apps have other sandbox path files that are not backed up is because those are generally data that can be regenerated during running, so they will come back when they are used and occupy space. Another case is that some pictures and video files of im software may not be placed in the sandbox documents when saved locally, so your operation may cause, for example, many multimedia resources in WeChat to be cleaned up and cannot be regenerated (that is, it is displayed as more than seven days has expired)

Poster May 6, 2025@ Anonymous13183 I am more concerned about WeChat chat records! Have you actually tested it? After the old phone data is migrated to the new iPhone through iTunes, the old WeChat chat file shows "expired"? After several migrations of my own, I found that it was not actually the case, and I could still see it all.

Anonymous9688 May 6, 2025@ Anonymous10816 Recording prores will prompt that the storage space is insufficient. You can use the system to clear it. However, it is not clear what the cleaning contents are.

Anonymous13183 May 6, 2025@ Poster It depends on the implementation of the app. I can only tell you the principle of iOS backup. In my impression, some pictures and videos on WeChat seem to be problematic files. The voice is not sure
