Why can’t I update from iOS15.7 to iOS16?
Cause 1: Insufficient battery power
iOS updates take time. If the iPhone is not fully charged and the update is performed, the battery will run out in the middle, the update will not be possible, or an error will prevent the update from completing safely.
Cause 2: Insufficient storage space
The update downloads the necessary data from Apple’s servers and stores it on your iPhone. If the iPhone does not have enough free space, the update will not proceed because the data cannot be saved. In this case, you need to delete unnecessary photos, videos, apps, etc. to secure space.
Cause 3: iPhone is not a compatible model
The iPhone models that will end support in iOS 16 are as follows: iPhone SE (1st generation)
iPhone 7, iPhone 7 Plus
iPhone 6s, iPhone 6s Plus
These iPhone models cannot update to iOS 16.
Cause 4: There is a network problem
An Internet environment such as Wifi is required to download the necessary files to the main unit during the update. Also, if the communication is unstable, it may not be able to update normally. Be careful not to make your internet connection unstable during the update.
