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.

I did that trick already; but thank you for the help!


I tried all the suggestions that I had not yet tried and it’s

still dimming & brightening on its own


I’m literally at a loss & quite perturbed because my profession is technology. I work on Apple products all the time and this one I can’t seem to solve. That’s when I reached out to the Apple “Forum” and found that thread on iPhone X “dimming issues.”


Looks like I’ll have to swallow my pride and get with Apple. Lol

Unfortunately there are no updates, at least from me. I’ve sent Apple my videos and have yet to hear back. I’ve even emailed the Apple representative and it’s been over 1.5 weeks and have yet to hear back. She was very fast to respond back to me via email at first and I haven’t hear back from her in a while. She said once she heard back from the engineers she will get back to me and that hasn’t happened yet.


Agree it is frustrating.

Wow, I would think there would be some sort of update on what’s going on by now. I have a senior advisor from apple support that is supposed to follow up with me tomorrow regarding an issue I am having with my AirPods. I am going to ask her about this and see if she can provide any updates. I will let this thread know if I find anything out. E

veryone I know that plays games on their iPhone X, is experiencing this same exact issue.

I know previous posters have taken their X into an Apple Store and have had diagnostic tests run and they show no issues. I am not sure what the issue is. Like today I was using Waze and it was super sunny and my phone did not dim. I did not have it on my dashboard as I had it in between my legs on the seat. I was using my work vehicle and did not have a mount so it was not directly in the sun.


I still think it is something with a sensor. Who knows what the deal is, it is very frustrating.

If

the screen dimming on its own is indeed a hardware issue (which I believe it is) and one that cannot be remedied by an update then we should be financially compensated and fairly. I’ve gone through two iPhone X, wasted way too much time both on multiple phone calls with Apple and time spent in the Apple store 3 different times regarding this issue and lost a batch of images along the way that didn’t complete uploading to the cloud before the Genius deleted my phone’s data having not checked that first.

This is not a minor issue imo, it’s a pain in the *** issue. You know this won’t be happening in the next iPhone X because they will have figured it out. The fact that they don’t acknowledge the issue is a real thumbs down for Apple. I’ve lost a lot of respect for the company because it’s not the first time they’ve blatantly ignored an issue.

That’s what they tell everyone. They’ll run a diagnostic, say the phone is working fine, they’ll check your settings that won’t be causing the issue, they’ll tell you to go home and see if the issue continues. It will continue and you’ll find yourself aggrevated yet in an effort to have a phone with a display that you can easily see with you’ll go back to the store, they’ll replace the phone and you’ll go home only to discover you have the same issue as before.

That’s not going to go well for them. I’ve ripped them a new one in the store before and I’ll do it again. Last time the manager called me, groveling. I won’t accept “go home.” I’ll accept a new phone. If that has a problem, they’ll be dealing with the relevant consumer fraud authorities. I’ve done it before with big companies. They don’t like when they get FTC and FCC inquiries.

Don’t waste your time by going to the. Apple Store. They will run diagnostics then tell you to call Apple! It’s a vicious cycle. I’m about to use that most expensive Protection Plan they tacked on to my “services” when I purchased the 6 years ago. I just haven’t wanted to go through all that mess but it’s inevitable. I’m going to have to take the time just to get a brand new one that does the exact same thing. And, every AT&T and Apple Rep, and Apple Care tell you that you are the FIRST person that has had this issue. I’m going in prepared this time. This is the most talked about problem with the X! No, I am. NOT the only one. Look at all these other X owners that have the exact same ISSUE! It’s definitely not just an issue but a TRUE PROBLEM and you will fix it somehow because I paid over a thousand dollars for a phone without problems. Problems were not part of this transaction.

I’m dimming and brightening back in fourth as I type this response now.

Uggggg

I sympathize, but respectfully disagree. I do appreciate the note about them pretending they've never seen it. That is not going to fly with me. Apple Support said they needed to research the issue and didn't bother taking me through the standard solutions because I told them I tried already. They basically punted and said to go to the store. I have an appointment for tomorrow. In the notes, I mentioned it was a known issue as reported here and elsewhere. I suspect they are going to replace the phone. If it the new one has the same issue, I'll cross that bridge at the time.

I appear to be having the same problem as many other new users of the iPhone X- only had 4 days and it appears to heat up and the display dims significantly fine all the obvious things and also contacted Apple who said they have never heard of this! Simply don’t know what to do now- this phone cost so much money too. Am becoming very frustrated


Any advice would be much appreciated.

Apple Inc. is not going to take responsibility for this issue! I have received two new iPhone X’s and they both including the original will DIM for no apparent reason. Obviously, this is an ongoing problem by the number of people having this issue And commenting on this thread. It’s an absolute shame that you pay $1200 for a phone that I cannot use outdoors!!!
