Some interesting comments here on the S8+ screen on time (S8 would not be far behind).

Actually overall, a very interesting review.

[Samsung Galaxy S8 Questions and Answers] Duck Quan:
I've seen threads where they say chip binning is related to poor battery life. If you have exynos you can go into download mode and check your chip numbers. Of they're high is means good battery life, if they're low, low battery life. I've noticed that most people with pre-ordered models suffered from poor chip binning. I did. I ended up getting a replacement S8 that had way better battery life (10 hrs with 3 sot compared to 17 hours with 5.5 sot). Now I've recently flashed the US unlocked firmware but I think that this firmwares battery life is worse than stock Sprint firmware
[Samsung Galaxy S8 Questions and Answers] dannytgt:
Chip number

I checked that numbers on download mode but on CHIP ID there's a combination of various numbers, high an low numbers, so I can't establish if my numbers are high or low.

Think you can take a pic a day upload it? Or PM me the pic?
[Samsung Galaxy S8 Questions and Answers] methoddon1:
you know this story is bullsh*t right?! com on, higher # good battery, lower bad ?! Jesus...

Uninstall apps you're not using, freeze some Samsung apps and services with BK Disabler, kill your battery into a shutdown and charge it up without powering up the device... enjoy your extra time. I went from 14h, 4h sot to 20h, 5.5h sot easy by simply doing that. and I have most functions jamming 24/7 (AOD, NFC, etc... no GPS, no gaming)
[Samsung Galaxy S8 Questions and Answers] methoddon1:
and it's getting better with each day.

edit : wrong screenshot
[Samsung Galaxy S8 Questions and Answers] cavags5:
What's wrong with the red line?
[Samsung Galaxy S8 Questions and Answers] methoddon1:
what do you mean?
[Samsung Galaxy S8 Questions and Answers] cavags5:
Its just to see how much mAh screen drain.

And what phone is that wrong screenshot from?

Why not delete it?
[Samsung Galaxy S8 Questions and Answers] methoddon1:
oh, that's right... it's the time left stats... dot line.

the "wrong" screenshot is from Galaxy A5 2017 my custom rom.

is there a way to delete it... i only see option to edit text.
[Samsung Galaxy S8 Questions and Answers] cavags5:
Galaxy A5 one of the best in battery life, much better than s8.

Usually i use XDA legacy app, and its possible, if remove the text i think it will delete.,

You see a lot of videos and Netflix, Samsung consumes very less battery with that,

S8 its possible to reach 10h stock with some videos.
[Samsung Galaxy S8 Questions and Answers] Malik828:
which custom rom I want to flash on A5
[Samsung Galaxy S8 Questions and Answers] methoddon1:
2h Netflix, 1h YouTube, the rest is AOD, Edge lighting, NFC (lots of Samsung pay with Iris Scanner), Few phonecalls, messages, lots of Whatsapp, Viber, Telegram, XDA, Facebook Lite, Flipboard, News, brightness at 25% 2h, at 100% outside 1h, at 50% the rest of the cycle. 4g, sync all the time.

no music, no GPS, no gaming during this particular cycle...

p. s. here's the mah (clean screenshot without mah crossed out)
[Samsung Galaxy S8 Questions and Answers] methoddon1:
Screen set to FHD+

MethLab Rom but you can find it under the name ProtaX... read few pages back when you visit the thread... i stopped developing since my work season began... summer, time to make money, work trip. there is one cosmetic issue that I couldn't resolve, - when applying a theme Dialer won't theme. for better results change framework and use xposed modules (Amplify, PowerNap, Greenify (last one not necessary).

but there are many roms came 2 months later based of it ... no thanks were given... lol... here is the link to my g+ A5 2017 community, use Tab to find custom roms quicker, dialer is fixed in these roms that came after mine ⤵️⤵️⤵️

Ask [MENTION=5184669]methoddon1[/MENTION] he knows.

Its a good result, i think its the average result,

My usage, Yesterday all wifi, some pictures, Facebook app, browsing, Internet beta its good, xda, and some whatsapp.

Receive 4emails, but sync is off, AOD off, nfc off, i don't need it.

And i use QHD always. Auto brightness indoors.

Today, 4G when left home, im indoors but only 50% brightness, only auto when driving, because of the sun.

Its very hot here around 36 degrees, battery drain faster.

And maybe this battery its not enough until the end of the day..

Hang on very well a little better than s7edge, because standby its better.

[Samsung Galaxy S8 Questions and Answers] callumbr1:
Recently my battery has got worse from when I purchased it like 4 weeks ago. The first 3 weeks or so I was getting 24 hours and 5-6 hours SOT roughly.

Lately it has been more like 12 hours with about 3 hours SOT if that. I haven't changed any Settings. Wi-Fi on, location on, AOD on. Display set at FHD+. Any tips to help increase battery life? Thanks
[Samsung Galaxy S8 Questions and Answers] cavags5:
Location on its not a battery friendly, but could not be the main cause, could be apps you use, there are always updates that could messe with battery, i had to change my email app 2 days ago because the update was bad.

Usually i test 2 or 3 apps in one charge and see the consumption of all, the worst i uninstalled, i used a weather app, that works flawless and consumption is the best.

There is a bug too in s8 Nougat, i had it in nougat beta program and they fix in s7 but s8 brings it again, at least on the software i have, its the AOD even when its off, the notification is always on, after a reboot it stay on again.

Check screenshot, this drain too.
[Samsung Galaxy S8 Questions and Answers] acejin:
I'm having the exact same problem, and this is without any heavy use. No streaming, no gaming, no heavy apps, only Whatsapp and Chrome.
[Samsung Galaxy S8 Questions and Answers] callumbr1:
I had my display settings set at WQHD+. I have changed it back to FHD+ and have seen massive improvement. Not the best but a lot better so far with 45% left.
[Samsung Galaxy S8 Questions and Answers] raky_b:
It's not always like this, but i am really happy with s8's battery life.

It was my biggest concern when we found out it's capacity, but it seems they have optimised it very good.

At least for web surfing, gps navigation and and calls...things that I use the phone most for.

---------- Post added at 06:41 AM ---------- Previous post was at 06:31 AM ----------

I must ad that I do not play games and there is not installed on my device, also i not use phone for videos often(but lots of Spotify with BT headphones)...wifi and 4g is always both on, and brightness something about 75%.

Last few days I did not get 8h of sot,but what ever I do, it's never under 5h.

After few Xiaomi 's with smaller screen and even bigger battery capacity, I am amazed with this one.
[Samsung Galaxy S8 Questions and Answers] Phatballz:
Galaxy S8(Exynos)

Bluetooth NFC and AOD off.

Disabled some google apps.

I use my device mostly on gaming, texting and browsing. I have a crappy reception at my place (Philippines), if on airplane mode I guess I can squeeze out 7+ hours SoT.

Cheers!
[Samsung Galaxy S8 Questions and Answers] Rubbervuist:
hmm

I feel like I should be getting better battery from this phone. See attached screenshots.

This is with

- moderate usage

- a black theme,

- AOD on

- bluetooth & nfc off

- Location on battery saver

- Wifi sleep to never

- direct call, easy mute, palm swipe, smart alert & smart stay off

- minimal vibration feedback

- display at FHD+

- auto brightness off

- edge lighting off

- Most bloatware disabled through Package Disabler

Any thoughts?

I'm a new user, how do I post a picture?
[Samsung Galaxy S8 Questions and Answers] cavags5:
Relax dude, only after you have 10 comments you will be able to post screenshots.

just be careful with what you disable, you don't need much, check what is running on the background that you don't need and disable..

And put always to sleep all the apps you don't use much and don't need notifications.
[Samsung Galaxy S8 Questions and Answers] philipone69:
Well...exchanged the phone due to some screen issues. They gave me this one. Battery life is absolutely amazing.

I can not imagine how do you get 6-7-9h of SoT. My best was 6h (one time), but regulary I have only 4.5h. No game, video, NFC disabled. Black theme, always on wi-fi, stage cellular signal
[Samsung Galaxy S8 Questions and Answers] Gilley:
I cant even get 3 hours of SOT, i did package disabler and got rid of like everything that one article recommended and i saw no improvements. Today i have 1 hour 15 min SOT and i'm at 42% as we speak.
[Samsung Galaxy S8 Questions and Answers] philipone69:
I have to mention that i got an 950f witch is the exynos. My 4g reception is perfect (always full bars) but i mostly stay on wifi, brightness at 50%, rarely play any games, location off, 2 mail accounts syncing.

?? I've been averaging 5-6 OST no problem. Going a full 20+ hours in-between charges. Nougat + 10nm chip is doing the job. 40% brightness with auto. Anything higher is too bright unless outside. Yesterday/Today's cycle attached.
[Samsung Galaxy S8 Questions and Answers] echto:
Absolutely.
[Samsung Galaxy S8 Questions and Answers] dhorgas:
Battery life on the S8+ is brutally bad so far. I am seeing Android System and Android OS as the culprits, same as you. Compared to the S7 Edge it isn't even in the same league. I can practically watch the percent drain. Heck, just as I am posting this if dropped another 1%.

I've started utilizing Gsam Pro and Wakelock Detector to understand what is causing this. My setup is identical to that of my S7 Edge. So far it seems that the Google Play Services are not playing nicely. High Accuracy location seems to be triggering location based wakelock hundreds of times per hour. This results in about 1.1% battery drain per hour in standby. Battery drain during use is also bad, but I need time to assess that piece still. First attempt tonight to disable High Accuracy location scanning. We will see what happens. Signal strength is always high.

I have the Snapdragon S8+ model. My S7 Edge was Exynos.

Just dropped another 1%. Just wow.
[Samsung Galaxy S8 Questions and Answers] ubelai:
Most ignorant and useless comment award goes to you today buddy hahahaha.

I'm getting phenomenal battery out of this device. Makes my Note 5 seem like it has a dud battery.

These results are from my S8 G950F exynos variant, 4G the whole time with heavy use on Facebook, QHD screen quality, streaming and what not.

All I have to say it the battery is stellar, more than any Android device I've ever owned. :)
[Samsung Galaxy S8 Questions and Answers] eduardmc:
Im getting great battery but bad battery drain. (Stand by time) went to sleep at 11pm woke up at 4:30am. And lost about 10% in those 6 hours. I only have disable bixsy with PD. Any idea om what else to disable?
[Samsung Galaxy S8 Questions and Answers] ubelai:
Try disabling Always On Display. Drain is only slight but if it you want to change it, then this setting is the one you want to look at.
[Samsung Galaxy S8 Questions and Answers] Arshem:
With always on display

I have always on display turned on and this is my battery life after 9+ hours. I'd post a screenshot, but it's not allowing me to do so.

9 hours and 41 minutes ago I unplugged and I'm at 88%
[Samsung Galaxy S8 Questions and Answers] jeux_1:
S8 here: unplugged 7h 19min with 1h45 on screen, 45 min call on bluetooth, 60 % left

Always on display and WQHD+
[Samsung Galaxy S8 Questions and Answers] km8j:
My battery life is great during true standby. But "mixed" standby (i.e., brief screen use during the day) is horrible, consumed by Android OS and System.
[Samsung Galaxy S8 Questions and Answers] felixthecat:
isn't the battery drain dependent on the cpu ? like the s7.
[Samsung Galaxy S8 Questions and Answers] Desperado1987:
S8: 5 hours and 15 minutes SOT. 7% left
[Samsung Galaxy S8 Questions and Answers] km8j:
Yea but CPU isn't the cause of Android OS/System use.
[Samsung Galaxy S8 Questions and Answers] kevkid:
I have pretty good battery life
[Samsung Galaxy S8 Questions and Answers] dbornack:
Without hard numbers, or even getting my phone to point of dying, the battery life has been really really good. I play music, lots of SOT, a lot of texting, emails, etc. I'm very pleased with a smaller battery than I'm used to. Snap 835 is legit!

What processes are you seeing? I'm seeing a lot of GnssLocationProvider_ex and GnssLocationProvider_ex, as well as LocationManagerService and SyncLoopWakeLock. I am observing the same behavior as you it seems and far from stellar battery life.
[Samsung Galaxy S8 Questions and Answers] echto:
Here's mine.
[Samsung Galaxy S8 Questions and Answers] km8j:
Where are you seeing these process?
[Samsung Galaxy S8 Questions and Answers] dhorgas:
I'm using Gsam Pro and also Wakelock Detector to identify stray processes. I can see a number of wakelocks issued by those processes as well as correlate them between the two apps as being potentially problematic. These are subroutines of the main Android OS and Android System processes.
[Samsung Galaxy S8 Questions and Answers] km8j:
rooted?
[Samsung Galaxy S8 Questions and Answers] skivnit:
I'm getting nowhere near those SOT, it all really depends on the usage for me, I'm always on 4g I have 4 gmail accounts always syncing aod on and on my first charge I'm down to 20% with 10hrs uptime and 4 hours sot. I have gear s2 paired and I spent some time installing/updatingapps
[Samsung Galaxy S8 Questions and Answers] dhorgas:
No. You can use them without root with full functionality. You just need to use ADB to explicitly provide some additional permissions.
[Samsung Galaxy S8 Questions and Answers] philipone69:
I see a trend again. Europeans with exynos are consistently getting better battery life and SOT. It's just like last year....i had a hunch it will be like this.

More than likely software bloat. Is it safe to disable com.sec.imsservice? Some posts from older phones say it kills the dialer but I disabled and dialer is fine. What does it do? That's my culprit
[Samsung Galaxy S8 Questions and Answers] Duck Quan:
I have mine disabled and nothing wrong has happened so I think it's safe

---------- Post added at 09:44 PM ---------- Previous post was at 09:39 PM ----------

I take that back. If you disabled it you'll get a constantly reoccurring "IMs service has stopped message" that pops up every 2 seconds. I'd like to keep this disabled but it seems there's no way without getting the errors. Although, it didn't start doing the messages till I optimized and restarted my device
[Samsung Galaxy S8 Questions and Answers] rodfarva00:
I've been having terrible wakelock issues on my phone (GS8, AT&T), mostly seeming to stem from Google Play Services. I happened to be signed up for the beta program through google play. After taking myself out of the beta, uninstalling all updates for play services and letting it update to the stable version, my battery has been rock solid for a few hours. It's too soon to say for sure that this solved my problem, but if any of you are on the beta track it may be something you'd want to check out.
[Samsung Galaxy S8 Questions and Answers] km8j:
Just re-enabled from your feedback. When I look at BBS and Sensors, I see "Samsung DeX Home" (which I've disabled) and there is heavy use under Sensor: TMD4906 PROX (6), wakeup=true. My guess is DeX just represents overall Android OS/System use since they can't be differentiated. Any idea what this is?

I don't know how you guys are getting that good of battery life. I guess the Exynos is much better on battery, and I wonder if GSM is better on battery than CDMA, since it seems most people with an Exynos will probably have a GSM phone. I'm lucky to get 3 hours SOT with a black theme, black wallpaper, AOD off, and optimzed setting turned on, I do keep the screen set to WQHD tho.

For those of you getting good battery life (call it 5 hours+), what percent of your use is on average is "continuous"? By that, I mean not picking up your phone, sending a text and putting it down but watching a video or something for 2 hours at a time? My S8 (TMOUS) does outstanding just using the screen. I can watch 30 minutes of Netflix and lose only 3-5% (1080p screen). But when I use the phone on and off, battery disappears like a magic show.
