Unexpectedly shutting off

The other day I was on FaceTime with a friend of mine and when I reached to 6 percent my phone turned off by itself and I was able to power it back on and the phone wasn’t even dead is there a way of knowing if it’s the battery health or if its something else?

it started doing this when IOS 17 came out when I was on IOS 16 it didn’t shut itself off and it only happens on FaceTime

iPhone SE, iOS 17

If you go into Settings, under Battery, what does it say about the Battery health?


I see people on these forums claiming that you should replace the battery once the battery health drops below 80% – so if the phone starts shutting off "randomly" a lot and the battery health is also below 80%, that might indicate a new battery is in order.


If I remember correctly, once battery health declines enough, it's easier for instantaneous power demands (at some particular moment) to exceed what the battery can provide, leading to unexpected shutoffs. The first article below has a section on "Preventing Unexpected Shutdowns" that might be interesting.

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.


Remember, the right question often leads to the solution!



iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.


Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.


Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.
