I have noticed this new iPhone has a very aggressive auto-brightness. Wondering if the rest of forum has noticed this also or maybe it’s just this device.

iPhone 13 Pro Max Very aggressive auto brightness

Auto brightness is adaptive. If you manually adjust the brightness then auto brightness will remember that and try to adjust to that same brightness level when the ambient light level is the same. This is good because it allows us to customize our brightness levels, but it can also get out of sync if you manually bring the brightness way up or way down for any reason.
However, if you manually adjust it when you see it too bright or too dim for your liking then it should soon get back in sync. I’ve also heard that manually turning off auto brightness and then turning it back on will reset it back to the defaults, so you could try that too.

Chances are I may have received a faulty phone only because I notice the screen dim right when it changes and yet my brightness slider is all the way up.
Yes, I have to keep dialing my screen brightness back down. Maybe it’s adaptive and will learn what I prefer? I hope…
I’ve also noticed that the camera app really increases exposure/brightness on photos when the scene is dimly lit. You can see deep fusion or whatever kick in about 1 second after the shot and the clarity improves and the scene gets much brighter.

I think that’s the long exposure night mode kicking in. As you aim the camera at a dimly lit screen you can see night mode come on with a yellow indicator near the top of the screen by the flash indicator. It will say something like 1S or 2S to indicate that it is going to do a 1 or 2 second exposure. It can go all the way up to 10 or 15 seconds if it detects that the phone is on a tripod or something else to hold it steady. When it takes a long exposure you should keep the camera aimed at the subject for the full exposure time for the best results, holding it as still as possible.
The phone is unusually warm, when this happens and yet I am just browsing safari.
Never noticed this on iPhone 12 Pro Max.
Just an FYI - I noticed that the phone does not seem to reach max brightness if the "auto brightness" setting (in Accessibility) is turned on. Even if you have the slider all the way up, it doesn't seem to match a phone with the auto brightness turned off.
You can confirm this by testing two phones side by side (i.e., checking your phone against Apple Store display models). The in-store models have "auto brightness" turned off and are set to max brightness.

Yeah, I think that’s what you’re seeing and not autobrightness. The phone is probably running warmer than normal right now because of the restore and iCloud sync and indexing operations that happen during the first day with a new phone. I would expect that you won’t see this happening tomorrow while you’re browsing. It would happen with the 12 pro max as well if it gets too warm. I’ve seen it happen frequently if the phone is outside in direct sun on a warm day (which happens a lot here in Florida)
I was under the impression it would only reach max brightness if auto-brightness was on.
interesting
Is there a source that talks about this? Not disagreeing, but I have never read about auto brightness being adaptive to an individual users habits before.
I can definitely confirm this, at least indoors with conditions being equal — my 13 PM with AB on looked very dim compared to my 12 PM with AB off, with sliders on each all the way up. Once I turned off auto brightness on my 13 PM, it looked pretty equivalent to the 12 PM. Maybe a hair brighter
however, it’s possible the 13 PM would have boosted more, to its quoted 1000nits, going outside — not quite sure how this works yet
A quick google search brought up this article. I’m sure there are more if you look.

You can see this on your own if you play with it a little. Go to a room that’s got kind of a medium amount of ambient light and adjust the phone’s brightness level to, say, 1/3. Then go to a brighter or dimmer room and you can see the brightness go up or down to match the ambient light level. Then walk back to the original room and note that it goes back to where you set it.
Then adjust it manually again, to say 2/3. Again, go to a brighter or dimmer room and again you will see it go up or down to match. Then walk back to the original room and this time it will go to the new 2/3 setting.
Nope. Definitely not. Im very familiar with night mode, been using it since my iPhone 11 Pro on launch day. This isn’t that.
Their auto brightness has always been wacked! I usually keep my place on the "dark side", I don't like a lot of light in my apartment and at night, I have ambient lighting on. If I turn on auto brightness, it cranks the brightness all the way down to the bottom of the slider and I can barely read anything lol. Yes, it's way too aggressive!
It's not as bad on the iPads (even though it works the same), my guess is because it's a larger display the default font size is larger, it's a bit easier to see things. I usually use it on my iPad because I have backlight bleeding issues and if I'm watching videos with the brightness cranked up, some of the backlight bleeding really annoys me!

iPhone 13 here.
In most cases, auto brightness works perfectly for me. The exception is when I'm in a dark room...it turns the brightness way too low for my liking so I have to crank it up manually.
