What resolution do you guys have your S8 or s8+ on? Do you find it impacts battery life at all?

I use them all they save negligible battery according to battery saver mode in settings

Hello
Back in the days when I had an s3. I remember that the power saving mode had a significant effect on the battery life as well as performance.
Can anyone explain how the battery saving helps in gs4. I notice no performance difference here. Are the a15 cores still getting used when the mode is turned on?
Also, can anyone report better battery life with powersaver turned on vs off on i9500?
Thank You.

My GT-I9505 has always had a very poor battery life. However, thanks to Greenify and Amplify I managed to reduce the battery drain during deep sleep almost entirely. However, I noticed huge battery drain when the screen is on, it takes half of the battery and just for less than 2 hours of screen on! The brightness is set to minimum, I use Slimkat's Dark UI which it should help the AMOLED screen, but these battery drops keeps staying (even with other ROMs i have the same battery drain)... A friend of mine has got a Galaxy S5 and its battery is absolutely brilliant, screen takes only 20% in the battery stats and he uses it far more than me... Is this a normal attitude on the S4?

The S5 does have a bigger battery (bigger in terms of mAh). It also depends on the age of the battery. If the phone is new (therefor has a new battery) it obviously lasts longer. It also depends on what you are doing when the screen is on. Do you play games or what?
I usually read on my S4 and it does not drain so much as to go from 100% to 50% in 2 hours. But I'm running lollipop. I've never had any other rom beside original firmware and lollipop gpe.
Check your settings and governor.

Hi mate
Use an app like BBS let it run when the screen is on to really see what is keeping the phone awake

hey, i want to know if these 3 features drain battery or aid in better battery life
ambient display - i know it's an amoled so only few pixels are turned on, but what i want to know is do people face a much better battery life with this feature turned on and by that i mean like a significant difference, same with adaptive brightness as compared to toggling it yourself. And lastly black color on amoled screens, how much difference in battery life can you get approximately by using a black ui throughout, like 10% or 25% ?
the battery improvements are not noticeable. even in a full black background, but that's just my experience.

Honestly, the gains in battery life from using a black background would be pretty small in my opinion. I don't see how using ambient display would save any battery at all, as opposed to what? The biggest gain would be adjusting brightness manually instead of using adaptive brightness, adaptive brightness can be pretty heavy on the sensors.

I'm trying to compare ambient display to constantly unlocking the phone to check for the time or notifications

In that case I believe using ambient display would be the best option.
I've had my S7 Edge (Xynos) for a few days. I'm getting between 3-7hrs SOT depending how quickly I drain the battery and the screen brightness (30-70% brightness)
I've noticed my screen uses 30-50% of the battery capacity... is that normal?
I had an S7 non-edge (also Xynos) before and I'd get the same battery life but the screen would use 15-30% of the battery so this seems very high to me .
TIA

Screen battery usage depends on your usage and your settings:
For your usage, take the habbit to manually switch of the screen when you ends using your phone
For the settings, you can reduce duration before sleep and reduce brightness.
Screen IS the biggest battery drainer. Looks normal to me
Which option are you using guys on a daily basis?
Thanks :good:
Wqhd+
Same
Sent from my SM-G950F using XDA-Developers Legacy app
FHD+ for daily basis. Less Battery consuming.

Was trying different settings but can't really see the huge difference if any.
WQHD+ using the best resolution this phone can offer.lol
WQHD+
Haha, I'm using hd+. The battery life is great and honestly can't tell the difference between hd+ and fhd+.

You're blind
wqhd+ has the hit to battery life is very small If at all.
I use WQHD+. Anything lower and you can see the visible difference in quality. And there's no difference in battery.

There's negligible difference in battery.
Wouldnt WQHD+ cause lag in some games?
FHD+ I have no need for anything higher really.
Perfectly fine resolution and less of an impact on the GPU which offers more battery life, noticeable or not,
WQHD+
I tried FHD+ twice and it only gave me about 1-1.5 hours more of SOT. I also didn't like how the text looked fuzzy. With WQHD+ I already get 5-6 hours of SOT with 20-30% remaining before I go to bed and charge it.
I use fhd, although on heavy video session I switch to wqhd, the thing is fhd drops less frames than wqhd, so for day to day usage and multitasking fhd will be smoother and certain UI elements will load faster because of the less required pixels, yes it is a very small difference, milliseconds, but I like the speedy feeling, and the battery is a tiny bit better
I use WQHD+, according to http://www.anandtech.com/show/11540/samsung-galaxy-s8-exynos-versus-snapdragon/5
The S8’s settings menu offers a choice between several preset performance modes that affect sound quality, screen brightness, and screen resolution, among other things. For the results shown in the charts above, the S8s used the default “Optimized” setting that reduces the screen resolution to FHD+ (2220x1080). Running the PCMark battery test at its highest WQHD+ (2960x1440) setting has no appreciable affect on battery life, however, regardless of SoC.
