Screen on time

[gentlemanboy]

I'm using the regular s8 duos, SOT was around 6-7 h with moderate use one android 8.0 oreo and , i installed the 9.0 pie one ui beta currently on beta 3 the SOT has decreased drastically, now i get 3-4.5h of SOT.
So i'm wondering if the battery life will be better when the official update arrives or it's just another cheeky move to make me upgrade my phone or does the pie version drains battery faster in general ?
Is any one here experiencing the same because i will try the beta 4 if the battery keeps on dropping i think i will downgrade to 8.0 .

Settings used in both 8.0 and 9.0 :
Medium power saving mode
Cpu reduced to 70%
Fhd +
No always on display
40% of the day on 3g
Location mostly off
Charged overnight
Storage status 44.05/56 gb filled.
What i usually use it for:
40% opening pdf files
40% on social media
20% gaming

I installed the one ui beta from xda on the s8 and it decreased battery life drastically , i don't know if the official update will bring back the solide battery life on that i was getting on 8.0 oreo with the same moderate use

To be honest, I was facing 2,5h OST on 8.0, after factory reset, disabledmany system app and using greenify ,then I flashed 9.0 on my exynos s8 and it increased to 4hours~, atleast its giving more OST lmao

Galaxy s8 duos exynos

I've installed the 4th beta and it did boost my SOT by 2h compared to the previous betas, basically i'm almost getting the same sot as it was on oreo, i installed it today so i'm not sure if it will hold up, but it looks promising so far 33% with 4h45min of SOT with moderate to heavy use.

My device is like 1 year old maybe yours is affected with battery draining from aging, try using power saving mode it helps quite a bit.

Settings i use:
Medium power saving mode
Cpu reduced to 70%
No always on display
Video enhancer on
Fhd+ screen resolution
40% on mobile data
1h of pubg
Other on social media
With night mode on.

Something is wrong with your phone. I'm currently at almost 5 hours SOT with 30% left on the battery.

Just curious do you use whatsapp, Facebook and Instagram?

I have a theory that social apps kill battery.

I've owned Samsung S6, Nexus 6P, Sony Xperia and now my S8 which I can only get 3-4 hours screen on time maximum. All the other phones were even less!

But I have always used social media apps on all phones..

After the beta 4 one ui the battery has regained its performance, i'm getting 6-7h OST, i mainly use Facebook, Instagram and YouTube a lot with some reading and medium gaming.

Try activating medium power saving mode reduce cpu speed to 70% you won't notice any difference in performance cause even at 70% it's plenty powerful to run basic apps, dark theme, Fhd+, no always on, i get like 1-2h of extra SOT with this configuration. If nothing changes do a factory reset.


What's your software version ?
I m using the s8 duos

Hi,

I usually read a lot but don't post...
I have a Galaxy S8 on Oreo and i'm having around 3 hours SOT.

I've tried many things already. The only good thing now is the standby drain. At night i'm losing around 5% instead of 20% in the past.
As many of you i used to have a stellar battery life under Nougat. It isjust night and day compared to my Mi4c with its mediocre battery and its bad optimized SoC...


At the moment here is what i've done:
Flashed an official ROM (moving from Vodafone DE ROM to XEF France) with factory reset.
Using a black/dark theme from the store. I tried Substratum in the past. It looked good but was a pain in the butt everytime you have to update an app.
Followed Neomancr's guide on reddit
Using Naptime (adb permission granted, though i'm not sure it really changes something)
Using GsamBattery Monitor (adb permission granted)
Most of the day, Bluetooth is on as well as WI-FI (though should be off when idle according to Neomancr's guide, but i don't really see it because at the time i unlock my phone the wifi status icon is visible).

I'm mostly browsing the web, watching YouTube (Vanced edition), some social media and many 10-15 minutes of gaming everyday.
I wouldn't consider that as heavy use but seems so or maybe I did something wrong...
Screen resolution is set to WQHD+ (FullHD+ would bring me only 10-15 minutes more according to device management tool)...

Any idea, any suggestion?

I know it is possible to disable system app with package disabler but is it really efficient and safe?

Hi, I have an S8+ dual sim and I get 4 hours SOT (sometimes nearly 5 or 3 if I use it with shorts sessions) and I use also many social apps during the day. I had 3 to 3:30 SOT on my S5 Snapdragon 801 so I dont see an upgrade considering the battery size of each even with a 10nm CPU process.

Damn it. I don't know how you guys get so much sot. Mine will be 4 hrs max. Running on a stock android pie, G950FD, no root. Got worse after updating to pie. I had my phone for 1 year now.
I tried disabling background activity for all apps didn't work. Couldn't use bk disabler.
It is so much annoying. Please someone show me a sloution.

Are you using social medias like an average user ? I think this is pretty normal because I get the same.

No social medias.
Little linkedin, whatsapp and telegram.
No instagram, facebook or twitter
I just flashed a custom rom instead of my stock rom. Thought it might help.
I will wait for a few cycles to see how much it affects my battery
I am just jealous that others can get 6 to 8 hours of sot with heavy usage :'(

Me 4 to 4 and a half hour SOT one UI march update with stock ROM, stock kernel. I think custom ROM might help to reach at least 6h.

I am using custom ROM, was using LightRom Pie and it lasts me around 3.5H average, now using Alexis 7.5 and this is what I got. It's with NX24 kernel, might test out TPG kernel. If I watch movie ofcourse it can add another hour or so but I'm testing out my normal daily usage, WhatsApp, Instagram, Browser. And note that this is what I get after using Medium power saving (Limit 70% CPU), HD screen.

Ok this is what I'm getting too. I get similar results with mine. But when I said custom ROMs, I meant custom light pixel ROM which has no One UI/ Samsung experience heavy stuff.

My battery life was great until that pos android pie update samsung pushed. I honestly feel like it was done on purpose but who knows, the UI and battery before was so much better. Now I have to root but Id lose alot of my cool features like secure folder and the like.
