iPhone screen dims randomly

My iPhone X Screen dims on its own For about 10-15 minutes Then gets brighter again All on its own! I do not have auto brightness on I do not have tutone on I have no settings on that would affect the screen it’s very annoying paying $1200 for a phone and this is happening. I love Apple have every single product they make.


ANY THOUGHTS ON WHATS CAUSING THIS?


Thanks!

I have been having this issue also. I have noticed it more while testing an app that is currently under development. It seems to happen when the phone has been under a considerable load. While debugging - I can see the energy usage of the app is very high. After some time the phone begins to heat up. While looking into this, I found another thread that said it was because of heat. I am tending to think this is probably right. After the phone cools off it seems to go back to normal.

Hey Serge, I agree with you about Apple Support...I have another case open, different problem, and after at first being shown lots of interest and attention, I was without explanation shunted off to a different agent who went through the motions of contacting me once or twice, then abruptly stopped answering my calls and emails altogether. I think they just hope you go away. I decided long ago that the best way to deal with this stuff is to do the troubleshooting yourself, which is how I got here and (hopefully) found a solution.


So while I sympathize with rage induced by Apple's terrible and/or clueless customer service, I can't really do anything to help. But if a tech support agent told me that this is definitely a built-in feature you can't control, that would give me renewed hope that there was a good chance I could fix it.
