Why did users want to downgrade iOS?

The new iOS 18 is now available with plenty of features, like enhancements with shared AirTags and AirPods, innovative mood monitoring and journaling, generation of animated stickers from live photos, etc. which are favored by the public.

However, the latest iOS version also brings unpredictable errors and problems like iPhone software update failed or the iOS 18 not working properly on some iPhone models, which greatly influence the normal use of the iDevice.

Apart from these issues with the latest iOS 18 version, most Apple users are also having a lot of issues after the previous iOS 18 update and want to downgrade iOS 18 to 17 or even back to iOS 16. Here are some reasons:

● The new iOS version will take up a lot of space, there is not enough space for running others.
● After upgrading the iOS version, the device heats up and the battery life decreases, Bluetooth/Wi-Fi cannot connect, and the device crashes.
● When the new version of iOS is just released, there may be lags and bugs, and many users can't stand it.
● The new iOS version will block some applications that are compatible with the older one, which brings great inconvenience to the users.
● Users are accustomed to the older iOS version and may not like the changes on the new version of iOS.

Preparation: Back up iPhone/iPad data before downgrading iOS

The downgrading is like a factory reset thatwill wipe off your iDevice data. Therefore,to downgrade iOS to an earlier version, you will need to back up your iPhone or iPad beforehand.

When it comes to backup, iCloud/iTunes will be your first choice, but restoring to a lower iOS version from a backup on a higher version of iOS is not supported. For instance, when you back up your iPhone on iOS 18 using iCloud/iTunes, the backup data cannot be restored to iOS 17.
