iphone 13 pro max screen dimming

My new iPhone 13 Pro Max is dimming quite a bit as well as getting warm and there are no applications running. I have 1TB and have 490GB used. I wonder is it indexing behind the scenes after an IOS update. I just installed IOS 15.0.1. As I am typing this. no apps running, screen is 50% and auto brightness is off and back of the phone is hot to the touch. I have done all the recommended fixes but to no avail. I have restarted and it will go almost immediately into dim mode.

OK People this is how I fixed my black background iPhone 13 Pro Max;


  1. Go to Gear Box
  2. Accessibility

Go To Display & Tex Size… turn everything off except for Auto Brightness. Keep Auto Brightness on.


Good Luck, This worked for me.
