If it were mine and forced restart has no effect, I would either take it to an Apple Store, or back it up, (you must do that anyway), reset to factory, and restore the backup.

If it needs repairing you would need to do the first two before sending it in.

There is some risk so ensure you learn how to perform this.

I’m experiencing the exact same issue on an iPhone 13 after updating to iOS 18.6.2.

The phone keeps shutting down and now it only works properly when plugged into the charger, even though the battery health is still good.

I had no problems before the update, so I’m convinced this is an iOS issue rather than a hardware one.

Are other iPhone 13 users facing the same problem?

I don't suppose there is no way to go back on a previous software version? Because this entire problem started with this new version. I saw online as well some of the iphone 16 user as well facing same problem.

That cannot be done.

if if fails to correct it, repeat the above but do not restore your backup.

If that still fails, or if it w ill not set up at all, get it repaired.

I have an IPhone 13 Pro Max and it updated to 18.6.2 last night and now it keeps restarting. I can use the phone for a minute before it restarts. And it’s doing this over and over again. My battery health and storage are good. I tried resetting the settings but it did not help.

Having same issue on iPhone 16 Pro only since install of iOS 18.6.2. I’ve done all trouble shooting, including forced restart, battery is “Normal,” no storage issues.

I got the same issue since updating to the same iOS version 18.6.2 I’m on iPhone 12 Pro Max …. APPLEEEEE

Same happening here with iphone 13 mini..
