iPhone 12 Pro Max only charges when awake. How can I proceed?

[Synna]

My iPhone 12 Pro Max recently has this weird issue that it only charges when awake, e.g. I plug it in and the charging process only starts once I tap the screen. Then it continues to charge without any problems, even after it goes back to sleep. I have read that this was a common issue back in the "Xs era", but it seems to affect some of the current units too.

I am unsure on how I should proceed here. From my point of view, this is a software issue, but I am not sure whether it will ever get fixed. I could probably get a replacement device from Apple, as I am a) under warranty and b) do have Apple Care, but since I got the phone via the contract from my carrier, I expect Apple and the carrier going back and forth about who is responsible plus I don't really want to exchange my retail unit for one of the "exchange units" (Silly, I know).

So, while thinking about it, I am looking for advice here. What whould be the best course of action? Hope for a software update, for example iOS 15, to fix this? Report it to Apple right away and hope that they consider themselves responsible to get me a replacement?

Thanks for your input!

Edit: Other sources mentioning this can be found here, but there are no solutions there, unfortunately.

I assume you have tried restarting the phone, and also a full reset?

The thread you linked to in the Apple Community forum listed various actions to take, which if unsuccessful would lead to contacting Apple Support. That is what I would suggest also.

It may be something that will require you to get the phone replaced, and you have warranty and Apple Care coverage so you're in good shape. I wouldn't worry about difficulty between Apple and your carrier. The Apple Care coverage is coming from Apple, as is the warranty. They are the ones standing behind the phone.

Contact Apple Support, you can use the chat feature on their website and generally you get a response quite quickly.

Well, that's strange. I went over the list in the other threads again and tried waiting after plugging in the cable and after about a minute, the phone started charging without waking it up. I then removed the cable and connected it again, as I wanted to time how long it takes for the charging process to start, and then, it immediately started without waking the phone up.

I have found reports of 2s charging delays, but none about it taking so long, although I guess there must be a reason why the specialist in the Apple forum asked to wait for 60 seconds. It's also curious that the delay is gone when immediately starting the charging process again. I guess it's an issue of time between charges, because if I wait until the next "necessary charge", e.g. until it is down to about 25% battery from 100% battery, the long "charge lag" is there again.

Does that change my situation? Should I still contact support about this?

It sounds to me like your phone is working fine, and that you are now extremely sensitive to something is not worth worrying about. You have one of Apple's top iPhone models - relax and enjoy it!
