After updating to iOS 18.1.1 my iPhone 11 Pro has been shutting off randomly

It's a nearly new phone. Not that it means it doesn't have a battery problem.

Usually the way I tell it's shut itself down and re-started is that it tells me I need re-enter my code because it's been restarted. It didn't do that yesterday, so possibly it's fixed itself. That would be nice.

Hi Apple - After 18.1.1 update to iPhone 11 - The battery stopped charging beyond 20% and the Apple store support team identified it as an hardware issue (Board issue). Apple Service centre team has done all diagnostics including SiS diagnostic and they updated that the device needs to be replaced and it should be a paid service. I am not sure why it should be a paid service when there was no physical or liquid damage.

This update was a nightmare on my IPhone 11 and IPad. (ISO 18.1)

It caused me 4 days of getting my IPhone back to where it was, and two trips to my Verizon store.

I had all kinds of issues, was unable able to pair my IPhone to my IPad, loss of passcodes, rearranged my Icons, some even disappeared. A total mess up from Apple. The authors of this ISO should make sure these issues and others I’ve read were compatible before sending it out.

Right now I am very wary of updating ISO 18.2, which cannot be denied. Apple makes sure you do these updates and will show on your settings forever until you do them. If they don’t apply to you like pen & pencil you should be able to override them.

I’m having the same issue right now. Everything was working well before on iOS 17. I update my iPhone 11 to 18.1.1 and few hours later the phone restarted it self and got stuck on a Apple Loop. This happen to be before with the previous iOS 17. I connected to my PC and tried to run the update there but no luck. Ones 18.2 was released I tried to restore my iPhone and still didn’t restore. Now my iPhone is unusable and stuck on the restore screen.

I see you used 18.2rc and got your phone working for a bit and got the black screen again. I would like to try this route if you can share me the link on where you got the 18.2rc to install.

It’s been 4 days now without my phone and I’m trying everything before heading to the Apple Store to tell me that I need to buy an new phone 😡.

we have a sentitivity connection now i dont want to make a proplems for you

I have the same problem after the update 18.1.1 my phone is randomly shutting down. Sometimes 3 or 4 times a day

Thought it's the battery looks like its not.

This is happening to my wife who just did that update. Her phone won’t stop turning on and off. She can’t even write this post because of her phone rebooting over and over. Dont do the update!!

battery health 85%

iPHone 14. Battery "Maximum Capacity 97%." Not in a boot loop—mostly works normally but shuts down without apparent reason 0 to 3 times a day, usually re-starting itself.

Is your phone working now with 18.1.1?

This is happening to me right now. Nothing is working but I’m stuck on restore screen.

So this means you are using an iPhone 11 to and no issue with yours after the update?
