Horizontal line when connected to charger

Hello, brand new iPhone 13 Pro Max have a problem (I hope that it is just software bug). The problem is that when i connect it to charger or to Mac, after I lock it (turn of the screen) some kind of horizontal line appears on the screen and 1/3 of the screen is brighter then the rest of it. The line dissappers when I restart iPhone. I tried turning of TrueTone, auto brightness and tap to wake, but without effect. I have also noticed that when I connect it to charger and keep the screen on, the line won't appear. As soon as I lock it and the line appears. iOS 15.2.

iPhone 13 Pro Max, iOS 15

Thank you for the fast reaction. Everything is updated (apps and iOS), even I preinstalled iOS on my Mac. It happens just in normal indoor temps. I'm using the original cable that came in the box. There is no damage to the iPhone and i don't have screen protector. But there is an update to the problem. Yesterday evening, before going to bed, I put it to charge and in the morning the line is there every time i lock the phone (even without charger). So I gave the phone to service and I'm waiting. Maybe there is a problem with the screen or some kind of filter capacitor. Thank you again for your assistance.

Hello blagovest192,

Thanks for reaching out to Apple Support Communities. Upon review of your post, it seems that you have noticed a horizontal line on your iPhone display when you charge it. We can see why you’d want this taken care of, so let us help from here! We have a few questions to help narrow down the source of this issue:

Are all the apps on your iPhone updated as well?
Does this happen in very cold or very warm environments, or is it just normal indoor temperatures?
Are you charging with the cable that came with your iPhone?
Do you have any type of case or screen protector on the iPhone, and if so, does this still occur if you remove those?
Has there been any damage to the iPhone? (We understand it is new, but we want to make sure.)

Please let us know the answers to these questions, so we can continue assisting. Take care!
