iPhone screen dims randomly

Go to settings, general, accessibility, display accommodations and check that the “reduce white point” option is off.

I thought I did too until I followed those steps and discovered that Auto-Brightness was set to "on."

Turn of your True Tone from swipe down menu. It should stop changing.

My iPhone X dims on its own even when the auto dim settings are off. I brought the phone to the Apple store, they ran some diagnostic, it came up clear of issues and they even reset it. I still have the problem. On top of that, if I’m in iMessage and I type quickly the iMessage app will close and a random app will pop open. There’s no rhyme or reason.

I completely agree Pete193. Between online complaints as well as in store complaints they have to know by now. I wonder what percent it has to reach for them to say "if we don't acknowledge and respond appropriately the repercussion will impact us financially." The Genius' at the store have seen the issue. The last one I spoke to concluded that it had to be a software issue if replacing the phone didn't solve the problem. And that I would not be able to restore from backup if I wanted the problem resolved. Well, I want to utilize my backup, there's a reason it exist for all of us. And they should be working towards a fix rather than telling customers who have spent $1000 dollar on a cellphone that they can't have their existing data for that $1000 phone to work properly. There are other issues as well that I have encountered but rather than address them, the issues go ignored or bounced around until you get frustrated and just give up which I think they ultimately hope for.

I agree 100% with you that it is a software issue. As stated earlier in this growing thread my wife’s phone, iPhone 6 dims all on its own too.

Hoping Apple finally sees this is a bigger issue as the engineers are fully aware of this problem and they even have video of my screen dimming.

Question for anyone out there, have you noticed the screen returning to normal if you let it be? An example, I was running Waze and the screen dimmed. I let it be, continued to run Waze and after 10 minutes the screen slowly returned to normal brightness. I could see it slowly return to full brightness. Just puzzles me that this is occurring and I bet it happens to the majority of phones but people either don’t care or realize what’s happening so they are not reporting anything.

I don’t buy that explanation. I have had my screen dim w/in 5 minutes of use. There’s no way it gets that hot in 5 minutes.

Apple has not been able to explain the reason behind this issue. As I have stated in previous comments above Apple has screen recordings of my screen dimming and they have not gotten back to me yet. If the cause was heat related I believe they would have told me that’s the reason. They have not been able to tell me why it’s happening and that is why I feel it’s not a heat issue, it’s more of a software bug. I think it is a software related bug that needs to be fixed ASAP.

Wife wife used iPhone 6 and her sitting in the house searching the web her screen will dim. She isn’t doing anything else but reading books on Safari and her screen will get dark.

I hope a fix is soon. Very frustrating.

It happens to me all the time and I don’t use WAZE nor is it plugged in. It will go feom light to dark at anytime. 109% battery, no particular APP, etc. I’m not happy. it started doing it the update before the last one. These updates always seem to mess other iPhone options up!

But this light to dark malfunction has definitely been the WORSE of ALL the issues I’ve ever experienced with the iPhone and I go way back to the iPhone 3G!

Unfortunately, turning off Attention Aware did NOT help. I’m outside and the brightness still auto adjusted itself and I was in the shade, not bright sunshine. I did notice that the phone was in Power Save mode (nothing on my phone is set to dim screen automatically) so I turned Power Save mode off, closed all opened apps, went into the bright sun and at about 30-45 seconds later as I began to type this, the brightness returned.

So back to my original opinion that it’s not an Attention Aware issue.

It would be nice if someone from APPLE could actually chime in and say something to the effect of “Hey, we hear you all, we see that this is a common issue, we know you spent 1000. on a shiny new phone and we know that you shouldn’t be experincing this (my phone just dimmed while typing, then returned to normal brightness about 25 seconds later) we are getting to the bottom of it.” I guess they’re waiting for a class action lawsuit before they actually take it seriously.

Except that this is a user to user forum ans Apple's participation is minimal at best. Not only that, they have never, at least to my knowledge, acknowledged a "known issue" on here. You want acknowledgement, contact Apple support. Visit the genius bar. That's the only acknowledgement from Apple you're going to get if this is indeed a "known issue".

Unless the Genius’ and the Apple Care advisors are keeping the complaints about this issue to themselves I cannot imagine how Apple would be unaware. In my case alone I’ve had the issue with 2 iPhone Xs. As a result of the issue I’ve had conversations with a number of advisors and senior advisers over the phone and met with Genius’ at the Apple Store at least 3 times. The phone was replaced because the first Genius couldn’t understand why it was dimming no matter what he adjusted. The replacement phone still does it.

If in fact this is a heat issue, which I believe it is, the remedy shouldn’t result in diminishing visibility of the main component of the phone that customers primarily use. In other word, if heat is an issue and they have to deal with the heat then they should come up with a solution that does not make it hard for individual to use their iPhones. In regards to the iPhone X where I am experiencing the issue, it seems they released a product to has a major visibility issue and defect and still charged $1000 for it. Nowhere did I read any fine print or hear any advisory such as, “when you buy this product please be advised that you might not be able to view the screen properly if your phone gets to hot.”

A number of people in this thread alone have either spoke with an advisor or been to the Apple Store with this issue, it ain’t no secret. It would be nice if it was addressed.

Is there any update on this? I

have this issue daily and it seems like a lot of people do. It’s been happening for months now and happens whenever I am on my iPhone X continuesly or whenever I am playing a high FPS game, for example Fornite. It’s obviously a battery overheating issue, as like many others when this happens the back of my phone is also getting hotter. I have tried everything it says online to prevent it from heating up, but they are all bogus and don’t work.

I have been to the Apple store three times… They have replaced my phone twice, the first time backing up my data from the original phone. I didn’t make it to the parking lot and the phone dimmed. The second phone was Not backed up but ran as new device. This phone continues to Dim indoors and out!

It does not work, like any other settings. I just exchange my X yesterday and it does tha same think regardles any settings on or off. The resson for that problem is a poor quality new type of screen and Apple just protecting the integrity of the screen by diming it under bright lighting condition.

Hi David, have you had a chance to check out my youtube video. Also remove case if you have one and also remember that our new iPhone X is using the OLED technology instead of LCD now, so settings have changed, especially around black and white points.
