[Q] Android Pie Display Dimmer than Oreo? - Google Pixel 2 XL Questions & Answers

I just upgraded from 8.1 to 9.0 on my XL 2 over the weekend. I am stock rooted.
Is it just me or is the overall display brightness much less on Pie than it was on Oreo? In the same daytime environment, I feel like Pie needs to be around 70% brightness whereas on Oreo, I feel like the display was set on about 35%. I rarely had Oreo brightness above 50%. Now with Pie, I feel like I can barely see the screen when it's under 50%.
On Oreo, my display was set to Saturated and of course, white theme since that's all we had.
On Pie, I used the same settings and it looks much dimmer. I adjusted display to Boosted and have toogled back and forth between light and dark themes and I don't notice any difference with how much dimmer the overall display feels.

The display can still get just as bright. They've just changed the way the values are displayed from the slider is all.

Google changed the algorithm on the brightness slider. Therefore, 70% is the new 30% So, no, it's not you. Another brilliant improvement for the sake of supposed progress! ?

I agree with everyone else. 100% on 9 is still as bright as 100% was on 8.1 but 50% on 9 is NOT what 50% was on 8.1, no doubt about it. On 8x I usually kept my brightness around 65%... now on 9, to get something similar I am around 70-75%... If the same energy is being used to illuminate the display at the different values, batt life should remain about the same... But WHY?
Why change what 50% was on 8 to be different on 9? Isn't HALF the available illumination HALF the available illumination regardless of the OS version? What is the effect, or end game Google was looking for with this?

The max brightness is the same. The difference is the slider is no using a logarithmic algorithm instead of the old linear algorithm.
Here is the explanation of why it was done:
The first noteworthy feature is a changed brightness slider behavior: It now changes the brightness logarithmically instead of linearly. Before this preview when it was linear, about 90% of the brightness was controlled by the lower 20% of the left of the slider. The old 50% brightness was almost identical to 100% max brightness, and the old 5% brightness was significantly brighter than 0% brightness. Now, the change in perceptual brightness is more uniform as you increase or decrease the slider.

Exactly. 50% before was definitely not 50% nits output for the screen which, with a rated max 403 by anandtech, would be only 201.5 nits. And that was before the November update that lowered the max by 50 nits.

Doesn't really bother me. My normal brightness is now just like 60% instead of around 20%. Not sure why some freaked out about it.

Decrease Screen Brightness -> save battery

Hi,
I found this:
chart
Short explanation for non german reader:
max brightness
iphone 4: 486 cd/m²
SGS: 311 cd/m²
Nexus 1: 217 cd/m²
min brightness
iphone 4: 3 cd/m²
Nexus 1: 24 cd/m²
SGS: 84 cd/m²
As you can see, the screen brightness is still very very high, even if you set it to the lowest value.
So i took a look into the settings.db and saw, that the value for screen_brightness was 30, not 0. (I had set the brightness to the lowest possible before).
Maybe the Samsung preferences don't let you set the lowest available brightness?
I set the value to 0, but I'm not sure the brightness changed. =/
Someone else wanna try this and measure if the brightness really decreases?
Could save some battery...
Nice one, because of the technology we generally use less power than iPhone 4 for display HOWEVER if you display a lot of whites the AMOLED screen has the *POTENTIAL* (note: potential) to use 30% more power than the iPhone 4's H-IPS Backlit LCD.
So, another power saver tip is to use dark backgrounds as white/light ones use a lot more display power. This is a side effect of the AMOLED technology.
This is probably the biggest quibble I've with this phone right now, so I was glad to find this post from supercurio's (creater of Voodoo) twitter: "Wow, minimum brightness on #GalaxyS can be tweaked to extremely low levels !"
I hope he'll share these findings with us soon.
Its pissing me off sooo much. Like at night even at min brightness its too bright, browsing market blinds me. Can't wait for supercurio's thing, he said he got the profiles figured out.
For now all i know is 18 is the lowest u can go, anything below just completely turns the backlight off.
You guys tried dimmer from market? Goes to 10.

I simply pay more attention to my brightness now and control it myself. It adds to the to do list BUT I have gained about 30% battery life per day by doing it.
I find unless I'm in the sun there is no need to go beyond 38%.

What are your Screen Filter Presets for Galaxy S3?

I think the lowest brightness is too bright and want something slightly lower. The brighter end of the phone is too bright and I end up wasting a lot of my brightness slider doing nothing. I want the highest preset to be pretty low too but settings presets requires a lot of playing around. I was wondering in the above situation what are some good presets for the following values that other SG3 users have set?
25%
40%
55%
70%
85%
I know at night my dimness is set to 48.6% which should be my 25%. How would I calculate the rest based on that, especially the upper limit?

auto brightness

Running your pixel 2 xl on auto brightness is good or bad? Does it use more or less battery?

It doesn't use much battery compared to Adaptive Brightness off unless you keep your screen at something low like 10% or less the whole time.

I've always, even with previous phones, used manual brightness. Partly because I am usually happy with brightness to be kept at, for this device, at 15% and if I need to adjust Ill use Brightness Control. I also feel that battery life must surely be better as the sensor isn't constantly being used to gauge how bright the screen should be and lastly always found autobrightness to increase/decrease the screen brightness randomly, e.g. Say in my living room and it'll just increase/decrease slightly.
So ultimately I'm very happy just to manually adjust

Mine is set to.20% with auto brightness enabled. At most times it hovers very close to 20%. I guess if i disabled auto brightness i will get better battery life. At the moment i average 7 hrs SOT.
So what do you achieve in terms of SOT at 15% brightness

Brightness

Anyone else think the brightness is not very bright? I have turned auto brightness of but slider is on around 75 to 80% in normal conditions?
Seems fine to me. Depends entirely on what you are comparing it to, though.
With the brightness dialed all the way up, it looks either brighter or dimmer than my P2XL depending on the angle, so...
I have come from iphone x and (work phone) huawei p20 pro.
Right way up or 80% is fine but say half way 50% is loads lower than most other phones

The display could be brighter, I feel 100% should have been what 90% would be. 50 and below is too dark to be used at all imo.
If it just flat doesn't get bright enough for you you're kinda screwed. If you're wondering about auto brightness you gotta keep on cranking it up for a week or so before it starts giving in and giving you what you asked for; at least this was the case with my 3 XL. Seems to be the case here, mine is still slowly but surely getting brighter as I keep on dutifully upping it to the desired setting in various conditions. It worked very well before, the best I've used so far and I'm hoping the same will go on here.
The auto-brightness is supposed to be fairly intelligent BTW: As an example it's supposed to recognize the middle of the night and that your sleeping and turn the brightness down more with the same brightness information available than it would in the early evening when it knows you're awake. As an FYI the adaptive battery feature also seemed to need some time to figure out what it wanted to do. I had my 3XL for about a week last fall and the battery situation was slowly but surely getting better every day just like the auto brightness. No idea if either would have continued to improve after I sent that one back but they both needed time, that was for sure.

Question Full brightness for ever?

I've configured my screen brightness to maximum and disabled "Adaptive Brightness" and "Comfort Tone".. Despite this, the device "decides" from time to time to reduce brightness.. How can I resolve this? I want brightness to be on maximum all the time no matter what..
I'm guessing that is does this because it's bad for the device to have full brightness on all the time.
First of all, why would you want to be on max brightness ? It will hurt your eyes in the dark, drain your battery and it may cause burn-in in long term.
Anyway, to answer your question, it reduces its brightness probably because of heating. An higher brightness means a higher temperature. To solve that, it may be possible to do that via magisk but i've never heard of something like this. Or you could try some custom roms that don't include that type of software cooling system.

Thanks! When the brightness gets low it hurts my eyes.. On my smasung galaxy s21 ultra, it never reduces brightness.. Why? simply because that's what I choose. It seems that oneplus would not let me choose to work with high brightness all the time.

Oh i see. Isn't this related to DC dimming ? If so some custom roms may support that.

Low brightness doesn't harm your eyes. It may cause muscle strain because you can't focus properly; harmless.
Full brightness can demage your retina over time especially viewing it in a dark environment.
Full brightness will greatly decrease the display lifespan of a AMOLED.
The blue pixels die first.
Use manual brightness control and try to limit it to no more than needed, 50% or less is best.
Do not use in direct sunlight for more then a few seconds.

It's a bug, i've same problem, it lowers brightness by itsself! Me too have all disabled, annoying bug.

Except it's not a bug. It's a feature. More likely multiple features designed to improve the health and longevity of the device. That said, I'm all for individual choice. If a user really wants to risk damage to their device as well as their own vision, they should be free to do so. It does make sense, however, that such an option wouldn't be in plain sight in the Settings app.
Have you tried any 3rd party apps that support High Brightness Mode/HBM? Most will probably require root since HBM is a hardware-level setting (brighter than just moving the slider to max). I don't know if there's a way to do it more permanently with adb or not.

Custom roms are always dimmer than OxygenOS, have you never noticed this?
On OxygenOS I can have my brightness at 50% and see the phone fine, on custom roms I need to have it around 75-80% to get the same brightness

Don't know, I haven't tried custom roms yet on my 9 Pro. But I remember it was like you said on my 5T.
