Apple today pushed the official version of iOS 17.2.1 to users, which mainly fixes the problem of excessive power consumption in certain scenarios!


#In order to ensure the security of the device operating system and encourage users to update in a timely manner, Apple usually closes the verification channel for older versions of iOS after a new version is released. Therefore, with the launch of the latest versions of iOS 17.2 and iOS 17.2.1, Apple has also stopped verification support for iOS 17.1.1 and iOS 17.1.2, which means that iPhone users cannot downgrade to these two versions. This move is aimed at ensuring the security of user devices and prompting users to update to more secure operating system versions in a timely manner.


Currently, users can upgrade to iOS 17.2.1, iOS 17.2, and iOS 17.3beta. If you have upgraded to iOS 17.2.1 at the first time, you can downgrade to iOS 17.2.1. The only version available is iOS 17.2.
