Issues with iOS 17.2.1 on iPhone XS Max

I am currently encountering issues with my iPhone XS Max after updating it to iOS 17.2.1 recently. I have observed that after about an hour or 2 hours of usage, some applications start freezing, and the phone stops responding. I would try to switch it off by pressing the power button and the up volume key but it wont respond. I would also use Siri command to "restart my phone" but it wouldn't work as well. It will take over 30 minutes before the phone restarts itself and it is not encouraging.


Please, how can I solve this issue and if it cannot be solved, how can I revert back to iOS version 16.xxx in order to have my peace of mind?


Thank you.

MacBook Pro 15″, macOS 13.6

Following the installation of iOS 17.2.1 on my iPhone XS Max, the device consistently undergoes a reboot every 5 minutes. Is there a resolution available for this issue, or could someone provide guidance on reverting to a previous iOS version?

You are not going to be able to downgrade to a lesser iOS version. This is not supported by Apple.


You may have a poor battery condition which cannot provide sufficient power for peak performance. What is the Battery Health of your iPhone? Open Settings  Battery  Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance. If your battery's Maximum Capacity shows a value of 80% or less, then it has gone through its lifecycle and therefore should be replaced, according to Apple.
