iphone 13 pro max screen dimming

did u guys try this? Turn the attention aware features off. It seems to be working for me. Let me know if it works for u guys as well!

Good luck to all of us😳

Hi guys,

I solved my screen being dim!

The zoom in function ( 3 taps on home screen with 3 fingers) when the menu opens select “filter - none” i managed to put mine out n low light.

Now back to its full brightness!!

Odd, it works on mine now. I had PNP watching nba game then it dimmed. Turned off the reduce whitepoint and its workign as it should. I also dont have attention awareness on. Still working 2 hours later.

I have the same issue. Tried fixes mentioned in this thread in warm conditions but didn’t get an improvement. Apple via their chat have said to turn True Tone off in the display settings. Hopefully I won’t have the issue when next in warm weather

As you didn’t say what “all of the afore mentioned solutions” were, you might see if you checked these.

If your phone dims in direct sunlight there are a couple of things to check:

Your phone has an “active” screen; that is, each pixel is an LED. If the phone is in direct sunlight it can get very hot, so hot that it is in danger of shutting down if the phone detects it is overheating. So iOS will dim the screen to reduce the amount of heat generated by the screen. If you move the phone to the shade, or shade it with your body, that will usually solve the problem. And, BTW, this is an issue with any phone with an LED screen, which is all newer phones, iPhone, Android, or anything else.

One setting to check is Settings/Face ID & Passcode/Attention Aware Features. If this is enabled when you are not looking at the phone (that is, the phone can’t see your eyes) it will dim the screen. If you are in the sun you are probably wearing sun glasses, so the phone can’t see your eyes and it will dim the screen if Attention Aware is enabled.

I took my phone back, they said I probably got a bad one. They replaced for free. Since the replacement I haven’t had the issue again.

The iPhone overheating and screen dimming is an issue starting mainly with iPhone 12 Pro Max which is what I have. I am a professional architect and have to take pictures in plus 90 to 100 degree weather. I can’t see my screen because the phone overheats in the sun constantly. The only other time it does this is when downloading a massive game. I researched into this and found that this is not a glitch or hardware problem. This is an intentional defense mechanism built into pro max models 12 pro max and going forward to keep the battery from becoming damaged when overheating. Android phones don’t have this issue because they are built to dissipate heat and have a system to regulate the heat without frying the battery. Let me know what others think and find out. I am curious if apple can address this with a software update.

The dimming has happened to me a few times and it just did so I came looking for an answer. I tried your trick but my "reduce white point" wasn't on so just for fun I turned it on and then off. That did the trick for me! Now we'll see how long this "fix" works until they get it taken care of - as mentioned above - too expensive of a phone to be doing this kind of crap....thanks for the tip!

I turned off the attention aware features so I hope this works!!

Turn off reduce whitepoint. Works for me 👍🏻

I had some success with turning off “reduce white point”. I also found that I like setting “Smart Invert” to on in this situation. Helps a bit too. I am starting to like using it all the time.

I just changed the setting now. I won't know if it works probably until summer when the phone cooks up some heat again or if I travel to a warm area.

New update to my last post…. This method / technique does not work. I was playing yesterday my call of duty mobile game on my iPhone 12 Pro Max and the dimming situation occurred again. …. I believe what the genius rep stated that apple wrote a piece of software to prevent the screen from overheated like in past iPhones. So if your screen dims that just means the screen was getting hot for whatever the reasoning for me it’s gaming. I hope this helps you understand not necessarily fixed the issue.

Try the trick above where you disable Attention Aware Features, it works. Did you not see that post? I’m surprised people keep posting having trouble when the solution has been posted.

I am seeing same behavior on my 13 Pro Max. I have lightly used it in my 70 degree house and it quickly dims to about half brightness. I have auto brightness off. Back of phone I'd say was warm but not "hot". I wonder if the temp sensors are dimming prematurely. this is a brighter phone in NITS then the other displays so wonder if it is generating heat too quickly.

I do have mine in a case so heat dissipation is slower but my 11 Pro Max in same Speck style case never had the issue.

Add this to the list of problems I'm seeing including Airdrop not working with wife's 13 max. I already regret upgrading. Should have kept my 11 Pro Max was working fine.
