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??
Sent from Flip's SGS2

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
Sent from my SGH-T989 using Tapatalk

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

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy S8+ before depleting the battery.
Then, drop a comment if you have anything to add!

Amazing battery life on the s8+

Battery life has been a bit inconsistent. Usually I get around 4 or 5 hours screen on time, though honestly my habit with all my phone Shas been to charge them whenever possible. If I'm driving, I set it on the mount and plug it in. If I'm at home or work and not using it, I plug it in (or in this case set it on the wireless charger). But I was fairly unimpressed with the S8+ battery life.
Yesterday and today, I turned on the medium battery power setting. It seems to have increased my screen on time dramatically, but I'm also at home and on wifi.
Medium decreases screen brightness by 10%, sets resolution to FHD+, underclocks by 30%, and turns off the AOD. Of these, the only thing I miss is the AOD, but it also seems to make the most difference in battery life.
Either way, my battery life today is much better. So far I've had almost five and a half hours of screen on time and 54% battery remaining. That's all surfing the internet, posting here, texting my wife, taking a few photos, and a little Facebook. I'd say that is fairly impressive.
I'll see how the battery holds out Monday when I'm away from wifi, driving through varying cell tower coverage areas. I'll also check how it is if I turn the AOD back on. I do like the AOD.

Really good for a stock rom

Bat Rom & Noto.
Could of got to 10hrs but was playing with themes which require reboots.

Do you notice any decreases in performances with the underclocking? Or are things still fairly snappy?

I don't notice any performance issues at all with it underclocked. But I don't do any gaming either, so that may be an issue for others.

ambient display battery usage

How many of you are using the ambient display and how much battery does it drain in average?
I had it turned on from day one, but want to use it for the cool now listening songs feature while screen is off

I can't tell you how much exactly but it is a noticeable amount.

I Use ambient display, but don't really notice my battery taking a hit...

If you keep it in you pocket or face down (proximity sensor turns off the display on said conditions) when you're not using your phone the battery drain isn't noticeable

why not just try it and see how much it affects you?
I notice no drain from it at all, doesnt mean you will or wont however.

Been using it since day one and I'm fine with whatever minimal drain it does.
Sent from my Pixel 2 XL using Tapatalk

It would have to use some amount not matter what. People that state they don't notice a difference etc is not possible. So there is no doubt about it. It will definitely get a hit. I suggest you try it for a day or two and see how you go

It is both.
In few cases it affect battery life.
In few cases it saves battery life.
My usage of phone ambience more than 90% of time is same so I manually set brightness. Enabling adaptiveness affected battery life.
However for others whose ambience changes from low brightness to high brightness, enabling it may save battery. Auto setting feature of phone do consume battery but battery saving provided by auto setting can be less or more depending on usage.

Hi
It all depends on your usage. If you regularly use your phone during the day, so need to charge your phone every day, than the percentage of power used by Ambient display is low compared to the phone usage, so it wouldn't seem to impact much on the battery. If however you are a light user of the phone (for example I can go 3 to 5 days sometimes without needing to charge my XL), then having Ambient display turned on would probably half or more your standby time.
This is why some people will see extra power drain, others it goes un-noticed.
Regards
Phil

actually I had measure battery drain between ambient display ON or OFF (I let double tap and life to check phone ON).
based on my actual results, ambient ON takes 47 mAh and ambient OFF takes 9.1 mAh. To put simply, ambient ON drain 1.5%/hour while ambient OFF drain 0.3%/hour. In summary, putting ON ambient display will takes 1.2%/hour.

When ambient is ON I measure for 6 hours, and while OFF only about 2 hours.
I'm using AccuBattery to get the numbers

[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! ?

Probably hanging out with this guy! ???

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.
