auto brightness or not? - G3 Q&A, Help & Troubleshooting

So my question is this...on android. I do remember auto brightness being a bad thing way back when as far as battery life goes. Is this still the case? I have been using my g3 at 47% brightness with auto enabled. Battery was OK, but screen just seemed so...dim. Pumping it up would just murder my battery performance.
I am curious to what people are using and how their battery performance is.

As far as I'm away auto-brightness will always have the downside with poor battery performance as it constantly ramps up and down the brightness.
I've found that:
0 brightness is perfect for darkness / night time.
0 - 30 brightness is perfect for indoors
60 - 80 is perfect for outdoors
80+ isn't required as I can still see the screen (with a strugle) but it works.

That is what I thought.
Thank you for the additional information regarding the brightness levels!

Power Saving Mode?

What's that do? It's on the display menu. Turned it off and didn't noticed a diff.
Was playing with a Nexus S at Sprint. Picked it up and it had system updates waiting...cool. Comparing everything side by side... very similiar performance to epic: screen rotation, sig strength, data speed.
Nexus display seemed a little "crisper" and for the first time in a while, I noticed the bluish tint on my display....

It dulls the white when it thinks it should. Turn it off, it only waste battery life from polling; Just like auto screen brightness, its BS unless you go in and out of dark/bright areas all the time, it polls about every 1 or 2 seconds, what a waste, just put it on 50%, I've seen the best battery results from this. The voltage used at 50% when scaled to 100% is more then when scaled from lowest brightness to 50%, in short 50% uses the least amount of power compared to lowest and highest setting, just trust me...
Im getting tired of changing this...

^^ This I find difficult to believe. The greater the brightness the more power is used, so if the lowest brightness setting remains static I doubt it uses more power than 50% setting. If anything, the opposite is true.

You're talking about the automatic brightness setting.. he means powersave mode.. which I have no idea what it is..

Ok here is what I mean, say at 0% on the slider is .9v , 50% is 1.1v, and 100% is 1.5v, 50% would be the best of both worlds, you can stillsee the screen and you save more compared to 0% - 50%, then 50% - 100%, its not that hard to understand...
And Chris, the power saving mode adjust white level (not brightness) when veiwing a bright page, or scene or pic...

So, simply put, turn off Power saving mode, and set the brigness to ~50 percent, instead of all the way down or up?

Any of you see a big battery difference with brightness??

So I've always used my phones with automatic brightness, but it seemed like this one would always be really low. The only time I would see the brightness change at all was when I'd take my phone out in the day when it was sunny. So I decided to switch it to full brightness on all the time and haven't really noticed a big difference in battery life. Plus with such a great display it looks so much better with the full brightness on. Any of you tried this and notice a big battery drain??

Im the opposite of you. If i have my brightness pass mid, my battery will be drained in no time. So i am forced to use low. I cant even use Auto Adjust, because that will also use a lot of battery. Mid and higher, my battery drainage will be around 59%-65%
For me full brightness really kills my battery. I I used to do full brightness but after going on my quest to improve my battery life I ended up sticking with ~50% brightness

The display is (generally) the biggest drain on your battery, so adjusting the brightness level accordingly definitely has an effect one way or the other. If I'm not in direct sunlight I leave my brightness very low, usually around ~15-20%
One of the biggest battery savers I found was a new watch my wife bought me. No more turning the display on/off throughout the day just to see what time it is

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

[Q] Android Pie Display Dimmer than Oreo?

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.

The same shìt as the retards who designed the P3XL.

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.
