My phone screen was useless during my 3 trips to Arizona this year. I wish you could truly override the temperature dimming. Taking off the Otterbox didn't make a difference and if anything got hotter. My work Samsung will wash out the colors but I've have yet to see it dim.
 
none of this really matters because all phones throttle the brightness after about 1 minute when its too hot (bright) especially in summer when you need more brightness and its hot outside
It’s so aggravating. I‘d like to read by the pool on my iphone, but the screen gets so dark that it’s unusable.

Pointless. Phones overheat in the sun within minutes negating any nits advantage on the 14 pro max. Perhaps make the phones a little thicker and have decent cooling or stop with this waterproof nonsense and have holes at the side to aid cooling.
 
Not in the south it won’t. Less than 5 minutes of direct sun and the screen begins getting dimmer due to heat, and shuts the phone down into safety mode after 10 or so minutes. Am I frequently using my phone in direct sunlight? No. Do I occasionally? Yes. Not complaining about the feature, it’s only an improvement. I just can’t see it helping my bright sunlight use situations unless they’ve improved cooling. However, a brighter screen makes me think of even more heat than before.

Edit: looks like I’m not the first. I rarely read the comments before posting lol.
 
It will be pointless because the phone will dim because of heat. Hot summer sunny days in Santorini made my iPhone 13 Pro’s screen so dim while taking photos. And GPS made the phone warm so screen dimming again.
Greek here and yes I confirm your worries...Here in Athens we have maybe...360 sunny days per year... We are mid September and the max temperature will stay above 30 celsius for another two-three weeks or sth...

All depends if there’s improved cooling or not.
 
This is also the one thing I'd still "jailbreak" or otherwise side load some stuff for. I hardly believe the phone would catastrophically combust if it were allowed to stay bright during higher heat operation. I'd rather let the device throttle the SOC and get all the way to the thermal limit if I could keep the brightness higher for longer.
 
Same here. I’ve never seen my 13 dim on its own. I have truetone and auto brightness off. Maybe that’s it?


I have had True Tone and auto brightness off for the last 3-4 generations of iPhone. Still dims aggressively when trying to take a few photos or a movie outside in the sun. I've gotten it to dim without being in direct sunlight too.

It's so aggressive if I'm out hiking or driving a Jeep trail out somewhere in the mountains and take a few videos outside, I can no longer see the display at all.


If it's summer where you are, go out in the sun and record a couple 30-45 second videos with the brightness all the way up. It'll very likely dim itself.
 
THIS is by far one of the greatest reason I am upgrading from my iPhone X...my battery is confirmed degrading from Apple though not in a rush ..hopefully by December or January I can get the iPhone Pro 14
 
Yeah, overheating from the sun usually ruins any brightness gains the screen gets. I'm hoping the A16 is more efficient to hopefully have more headroom before overheating from sunlight (Given it didn't get much in the way of performance gains.)
This. My phone was practically unusable during a good chunck of our summer vacation because we spent a lot of time at the pool and beach. Every time I went to snap a pic or play music, it was bricked from the heat.
 
I don't know what to think of this. My trusty old XS max keeps dropping the backlight when plugged in my car.
I don't know if it's related to carplay but is a mess. When the sun shines trough the windshield it actually gets dimmer, not brighter.
Is it related to temperature ? Whatever it is the algorithm drives me nuts, so having a phone that shines brighter might be nice... only if it works as expected 🙄
My XS Max does the same and I don't have CarPlay. It's the heat. Using my phone for directions on long roadtrips also causes it to get warm, dim, and start lagging. It's also plugged in charging because of the battery toll from GPS, which makes it even hotter. Forget about using it at the beach on a hot day in direct sunlight. It overheats and shuts down after just a few minutes.

The only thing that would truly solve the dimming in sunlight/heat issue is to switch the phone display to a color e-ink display. Like this one:

PocketBook-InkPad-Color-7-8-E-Ink-eReader-07-1200x900.jpg


The issue there, of course, is color palette limitations and refresh rate is non-existent. You’d have to be fine with a phone that can never play games with movement, watching videos, etc. For semi-static things like text messaging, phone calls, turn-based games, etc it would work pretty well.

Something that I think would help just as much as increased brightness, maybe more, would be better anti-reflective coating especially for people using dark mode. I have a top-of-the-range Samsung TV and that is like a black hole, pretty much no reflections even when turned off and in bright sunlight so that’s how good anti-reflective coatings can get and the iPhone coating is a million miles away from that.

In fairness the coating on a TV doesn’t have to be able to be swiped and prodded by potentially greasy fingers hundreds of times a day every day so maybe with current materials science all of those requirements are incompatible. I suspect that might be the case because Samsung provides handling pads to stick on the screen when it is being moved about so they really do not want you to touch the screen coating.

I do hope that better ant-reflective coating that can also be oleophobic and stand up to the UI requirements is something that Apple is researching, it would be a good innovation if Apple could get some better-than-everyone-else anti glare/reflection coating.

This is why I like my vent mount. If it’s hot out I invariably have my AC on, and it keeps my phone cool and display bright, even if it’s wirelessly charging and wirelessly streaming CarPlay.

That's a great point. I've never tried one because I use the heat half of the year and assumed it's probably not ideal to blow heat on the phone.

I just flick my vent off when it’s blowing heat, which seems to work fine. Generally if the heat is going the phone hasn’t struggled to maintain its temperature as it doesn’t have the hot sun beaming down onto it. :D
 
Did you find it effective and worth the dollars you gave .
1000% (on the brightness) and the battery life is better, Otherwise it's my least favorite iPhone to date. I loved the square edges of the iPhone 5 but in the 14Pro it's too big, blocky, heavy and uncomfortable to hold. The buttons are nearly impossible to press (compared to my round edge 11 or even a 13mini). The ridiculously oversized camera bumps get hung up on my jeans pocket every single time I try to slide it in my pocket, the "dynamic island" is always directly over faces in video content (videos play to the edge of screen under the island, unlike the notch phones that would play video fully below it). I could go on but :/

iPhone 11 Pro is the last great iPhone. Perfect thickness and camera size. Don’t know wtf Apple is doing.
