3-yr old iPhone 13 shuts down repeatedly after IOS 27.0.1 update - overheating in minutes with basic use.

3-yr old iPhone 13 shuts down after IOS 27.0.1 update - overheating with only 2-3 minutes of use.

The first shutdown was during a call, then it shutdown due to overheating with only a few minutes of basic use (checking email, opening a few apps). Now, I see horizontal lines across the top and bottom of the screen. I even tried removed a lot of apps a few days ago to see if would help, but sadly not. I bought a new battery in case that was the issue. Didn’t help, still shuts down after a few minutes, so the phone is unusable. I can’t restore back to 27.0 version either, given the current state of the phone.

Anyone else had a similar issue?

Bought a new battery from whom, exactly? Only Apple or actual Apple Authorized Service Providers can install an authentic battery in an iPhone. Anyone else would be using non-authentic parts.


I'd recommend scheduling an appointment at your closest Apple Store Genius Bar for evaluation and options. But if the phone was serviced by anyone other than Apple or Apple Authorized Service Provider, they may not be willing to fix the phone if something is wrong with it.

Sorry, confused.


I bought a new battery in case that was the issue.

So, this is the battery that is currently installed in your iPhone?


Battery capacity for the authentic battery is 85%

So, the battery that is currently installed in your iPhone is "authentic"? Or, are you referring to the original genuine battery that was installed in your iPhone.....before....it was replaced?


We ask because a "new" battery would be at 98-100% after a month or two of use.


Even a new battery would not help the issue that you are reporting if the logic board is having a problem. If you cannot take the phone in for service, Apple can provide you with information on an authorized shop that you can ship the phone to for repairs.

Unfortunately, if a non-authorized shop installed the "new" battery that you mention, Apple will likely refuse to service your iPhone because of tampering by an unauthorized person, so that may be another can of worms to deal with here.

Tap Settings > Battery

Tap Battery Health & Charging


What is the Maximum Capacity of the battery?


Are there any performance messages about the battery?


If you took the iPhone 13 in to an authorized Apple service shop, to have the battery replaced, they would not have returned the phone to you if it was still shutting down after a few minutes.....since additional repairs would have been required.


Tap on the link below to find a list of authorized Apple service shops in your area. Do you see the name of the shop that replaced the battery?

Unfortunately, i live in an isolated place and more than a plane ride away from an Apple Store, or would have done that first.

Battery capacity for the authentic battery is 85%. There are no performance messages.
