Updated my iPhone 12 Pro Max 256GB. Immediately after the update to iOS 16.2 my phone shuts down ever 10-15 minutes. I can’t keep it plugged into my computer enough time for a back up because phone shuts off.

Updated my iOS to the latest version (16.2) yesterday. I have an iPhone 12 Pro Max. It’s been a nightmare. Immediately after the update my phone shuts off everything 10-15 minutes. It first freezes, then a black screen pops up with that loading symbol in the center. Then after about two minutes, it goes black. Then after another minute or so the Apple logo comes back on. I can’t uninstall software. Can’t even keep it plugged into my Mac long enough to perform a back up because it shuts off.


please help

Three basic troubleshooting steps to perform (test after each attempt):


A) Try a "forced" restart of your device using these instructions:--> Force restart iPhone - Apple Support


B) If you can, check your battery status in Settings>Battery>Battery Health>Maximum capacity. If it is close to 82-80%, have it replaced.


C) If the issue persists, something could have gone wrong during the latest update procedure.

I would try to install a fresh copy of iOS/iPadOS (the latest available/supported by your device model). To do this, create a full backup of your iPhone/iPad (1), then restore it to factory settings (you need a computer to perform this step) and, in the end, set it up as new (2).

When done, restore data from your previously made backup (3).

Follow the instructions provided in these support articles:

(1) How to back up your iPhone, iPad, and iPod touch – Apple Support

(2) Restore your iPhone, iPad, or iPod to factory settings – Apple Support

(3) Restore your iPhone, iPad, or iPod touch from a backup


If the issue still persists, it could be a hardware (digitizer? screen? other internal component?) failure but we, just users like you, cannot diagnose that issue remotely, sorry.

I suggest that you make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector. After checking it out, they'll give you all the available options.

Regards

Giulio
