According to gsam Google service Is the culprit if ny high awake times (see screenshot below). But how can I reduce this problem without defeating the purpose of having a smartphone,and according to the battery graph u don't see Google services listed at all.
/facepalm
A 21-minute wakelock out of a 12 hour recording session. The sky must be falling.
Unless you shut down any Google app using Google Play Services, no, there's nothing to do. The only reason it comes up as a larger power use is because it's essentially aggregating the power previously used by six or seven different apps. You seriously need to get some perspective on what constitutes "bad" battery life because you just keep posting "my battery suxorz" threads with less and less justification each time.
Hmm. I get pretty crappy battery life, but that battery life doesn't look too good. How much screen time? Your kernel should use about 25% of your battery. If you're on stock, that is.
Try clearing cache for GP services. Try using the phone for a day. See if that works. If not, then clear data.

Here is my current stats also I'm completely stock (no root) and my herbal US currently 23%,how much higher(percentage wise) can it get before it will start causing orovkens?
For stock non rooted,that seems about right. That's what I get. Around 13 hours a day with 3 how screen time.
Actually, you are getting much better battery life than I do.
What are your settings? WiFi? LTE? Battery saving apps? Facebook? I can't for the life if me get decent battery life. As I said, the kernel uses up 25% of my battery.
EDIT: Also, I looked at my stats, and it seems that Google services wakes my device a lot too. So yeah, your stats are normal. :good:
Is this normal for me? I left my phone overnight and it goes to deep sleep with barely no screen time but there's major drain. What is the difference between screen on time and awake? Is it some background services running? I checked the wakelocks and nothing seems wrong.
Edit: Looks like something is keeping the kernel awake. Does anyone know what is msm_hsic_host?

I only use the power saver with cpu,and data connection enabled,auto sync disabled,I'm on wifi when at home,and 3g/lte enabled when im away from home all the time,auto-sync disabled (no need for it). NFC and all location services are on all the time (google's location service along with GPS),brightness set from 0%-20% (depending on lighting conditions). I also use the facebook app with syncing disabled.If you have any other questions or if I missed something feel free to ask.

That's exactly what I do! But I get really crappy signal and I'm on mible data quite a bit. What am I missing out on?
What percent of battery does your kernel use?

it ranges from 20%-25%,once it got up to 28% but I was doing some heavy gaming,but after that it went down to 23% according to gsam's app sucker on the % power used screen. I'm rarely in a low signal area, but when I am i'm not in that area for long enough time for it to really impact my battery.

I'm going to have to agree here. I think people are expecting way to much out of these machines. Especially if your gaming and browsing a lot. Assuming your not crippling your smartphone functions by disabling data and such,This phone is only rated for about 3 or 4 hours screen on time max, especially while gaming. 12 hours of battery is perfectly fine. Especially for the use case of the OP.

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth
Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL
Greeny can also help but may need root
I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.
I loose only 2% for 7h of standby last night.
We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?
I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why
Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.
Delete it pls.

Ok as you know the phones with the Xynos chip has pretty rubbish battery life but I've found a temp fix until samsung hopefully fix the issue. You won't notice any slow down or compromise the use of your phone.
All it is is set your phone to mid battery save and keep all the settings on but limit the cpu.
You can still play all the latest games without a stutter, you can't tell the cpu is being throttled.
Try it for a day see what you think, I also have Always on Display turned off for extra savings.
Interesting, will give it a try today, been averaging 3h40m for 50% battery usage (Not run it down to 0% yet) so will be able to see if it improves much
Says it has added over 4 hours to my battery life estimate
Thanks for the suggestion, will be testing soon.
My issue with my Exynos S9 is the standby. It's not completely terrible unless I'm in a crowded bar or an area with zero reception, but I can never get it to be good. Even with everything disabled (location, sync, AOD, lots of apps, etc) I can't get it under 1.5% drain per hour. With it all on I can easily hit 5% drain per hour, sometimes more, which is weird, cause the actual SOT doesn't take much more than this; 8-10% when stationary on WiFi, 12-15% when moving on mobile data.
Seriously the SOT on this thing is great (FHD+, haven't tried QHD+ yet). I reckon I could easily hit 7 hours, possibly getting up to 10 if I'm just browsing/watching shows in bed all day. But dear god the standby is driving me nuts.

Standby drain will be higher if your phone is in a pocket, doze only kicks in when the phone is sitting completely still so no sensors are active like gyro etc (unless that has changed in Oreo)
So standby overnight should be significantly better than when you're out and about with it

Yeah makes sense, but it still drains 1% per hour overnight, whereas other phones I've used only drain about 0.5%.

That's also the consensus I've been seeing elsewhere.
No idea how to fix. Seems that only my HTC 10, which has horrible SOT (drains about 25% per hour) can get standby this good, and yet it's still worse than most other people's.
2.5% per hour on average during the day with location and sync (but not AOD) on is actually good for my S9, yet it's still poor compared to everyone else's it seems. Today, with location and sync off, I'm averaging 1.5% standby drain per hour. AccuBattery staying 86% deep sleep, whereas it's closer to 65% when location/sync are on.
idunnolol, maybe I have poor signal? I'm usually on 2-3 bars. Or maybe an app I use is sucking power? ¯\(°_o)/¯

There's a few people with this drain problem and up to now we're starting to think it might be related to the modem, as with the SIM removed the extra drain is gone
It also looks like it might be related to which region/CSC firmware you have running, I am running the United Kingdom O2U firmware and do not see this extra drain
But this is all theory / guesses right now, nothing solid

Yeah makes sense. I'm in Australia, not sure how to find my firmware version. I'm guessing it's in Software Information? But there are a lot of numbers.
I find the Exynos modems seem a little worse than the Snapdragon ones where I live, though it could just be the specific places where I work and travel.

I think I isolated the issue by disabling extra packages last night, but I don't know which of them. Will see after tonight for sure.
Can you please enable aod (even though it will be turned off between 12-7AM) and the facebook packages for a night? It will help us narrow down the issues.
I used your settings - fb -aod and still had drain.
Will flash the O2 firmware if the drain continues overnight.

I've always disabled both tbh, only left FB package manager or whatever it is needed for the GearVR on my S7 for a while when I was using the Gear, but got bored of that and disabled them all, AOD gets disabled straight away, phone definitely cannot be as deep sleeping if that is active, and the screen is using power the whole time too, albeit only the pixels that are lit, but still more than having it 100% off
I tested with AOD on and off on my S7 and got huge overnight drain with it enabled vs off, same throughout the day, the phone couldn't enter Doze fully iirc

I didn't think AOD will drain battery since it's turned off in that interval? I had a OK drain after factory reset with AOD on. So idk what the hell is happening.

I meant when I left it enabled and on the display the whole time, different phone and different version of Android though
Maybe after the factory reset, because the system apps are back to their original versions, drain is OK, then when they update back to the newest the bug is brought back? Or are you updating everything 100% before testing?
Samsung system apps get updated from the Samsung app store too so you'd need to sign into a Samsung account to update those iirc

Hey guys,
So i got my Ultra chunk on Jan 22nd (Italy shipments were early) and been testing it non stop on different scenarios on aprox. 10 charge cycles by now and i want to share some of them to find out which apps are draining it in standby idle and WHY CANT I GET MORE THAT 5.30hrs of SOT...i watch every Exynos battery life test on Youtube and I wonder why i cant get those kind of numbers on my phone... is it because of 512gb/16gb? is it because of apps/settings?
1st scenario NORMAL (before update)(with lots of apps on sleep) :
https://imgur.com/a/WDmsNZK
2nd scenario HEAVY (after the update) :
https://imgur.com/a/S5Etest
3rd scenario IDLE FOR 2.30hrs (after update):
https://imgur.com/a/p34u7WE
4th scenario without SS: There was a scenario where i only used camera for a day with lots of UHD and single take (which is heavy on cpu and takes lot of power and heats up the phone in cold weather) and it was around 20% with around 2hours of SOT and lots of camera time...
PS: also i want to add that i added every app and pic/video from my NOTE 8(which i got 4.30hr of SOT!!) and the app count with aprox~590apps (including system apps) and its only ~200gb after i copied bunch of movies to it. I cleared cached 2times by now, tried putting apps to sleep (around 260 of them) and then tried the same apps on deep sleep and today i deleted all of those to let system do that for me.
WHAT SHOULD I DO?

Which storage option and which variant? Exynos or SD?
what's your average SOT time when you're using it ?
Same issue
I doubt it's the 16gb/512gb configuration, and to be honest the first screenshot seems pretty reasonable, as youtuber tests are in perfect conditions and not switching apps or on mobile data.
So few questions:
WQHD/120Hz?
WiFi/5G/4G? If one of the later, what was your signal like?
Are literally all of your apps sleeping? If so that can actually be a drain if you're fully reopening apps that you use regularly. I would deep sleep anything you don't use often and let the system determine the rest
Emoji ap and chrome look like they're using quite a bit of battery considering very little use, have seen problems with chrome eating battery so might be worth finding a replacement.
Also seen smarthings has been said to be causing a lot of issues, but don't know if that's visible drain that gets reported or something that just causes it in the background.
Compared to my S10+, my s21u exynos seems to be closing apps way less aggressively i.e. YouTube Vanced is eating battery in the background unless I fully close it even if not watching a video. Hoping this improves with usage.
When starting from scratch (100%) with no apps open, my drain is like 0.6% per hour on WiFi with tap to make AOD, but seems to struggle to idle that well after use unless manually closing apps

So few questions:
WQHD/120Hz?
WiFi/5G/4G? If one of the later, what was your signal like?
Are literally all of your apps sleeping? If so that can actually be a drain if you're fully reopening apps that you use regularly. I would deep sleep anything you don't use often and let the system determine the rest

WQHD+ 120Hz
No reception here and i didn't put it on airplane mode but now im starting to do so i got 5.47hr of SOT this cycle
Wifi is 2.4ghz with good reception (not great), i had apps that i didn't use on sleeping (removed them) , then did kinda same selection on DEEP SLEEP (again removed them too) and wanted to system to configure it but now system is not putting anything to sleep so its 0 in all three sections.
i used emoji AR for the first time in that cycle so that's why its there and never appeared after that. Chrome beta makes phone heat up slightly but i like it and can't switch to other browsers because of numerous reasons...
and about smartthings, should i unistall it completly or should i disable something for it?
also i removed facedata and also found that FINGERPRINT SCANNER was on ALWAYS ON so i switched it off too.
deep sleep messed up the apps , should i put the apps on sleep again?
also my animation scales are all set at 0.5x in developer settings could that drain it too?
also i jumped straight from note 8 so i dont know about the tips and tricks that S20 users did, is there a specific set of settings that i should turn off/on?
EDIT: Wanted to add if you have goodlock on your phones too? i have everyworking goodlock mod on my phone from galaxy store ( they're available in store just like US), could one of them cause the drainings?
appreciate the replies !

Sounds like your apps are the problem. Go in the settings and restrict background data and background operation of them.
Google Play Services, Google Backup Transport and Framework are prime suspects.
Clear the data for all three.
Try blocking them with Karma Firewall*.

If you have a WiFi connection and have turned on WiFi calling, you shouldn't need to go into aeroplane mode.
This YouTube video explains the different sleep bins so worth a watch (
), but I would also let it settle for a few days if you're moving everything around every 5 minutes.
If it's saved passwords you are stuck in chrome for, I recommend a manager like bitwarden (works across all devices and browsers).
Good lock and animations shouldn't impact battery too much.
Did you use smart switch? Would always recommend a clean install, at least of settings.
Try charging your phone to full before bed, then seeing how much it drains overnight when asleep and if anything pops up on the battery usage that shouldn't
My battery on my S21 Ultra, 512GB, Exynos model has been outstanding.
When WiFi is on, I turn mobile data off
GPS is off
FHD+ display with 120hz
Adaptive brightness
Mail sync off
I don't play games on my phone, so no games installed.
I'm at 30% battery with nearly 7hrs SOT.

Wow, so it's not about the 512gb... great battery!
1.Did you use smartswitch when you started it?
2.how many apps you have approximately? Did you set up secure folder/dual apps
3.did you install any goodlock mods on it?
4.why fhd+? The qhd and fhd has the same batterylife according to phonearena test.
5.is your fingerprint reader set to always on? Do you have AOD on as well?
Appreciate the replies! Enjoy it

I tried deepsleep before too, it messes up the apps completely unlike the normal sleeping method, so im back to using that. Put 265apps to sleep yesterday. Idle battery drain is almost fixed after turning off aod/fingerprint always on sensor and also deleting smartthings, i dont know which one did that
I used smartswitch at fisrt, but only for moving media and contacts/messages, i didnt move the settings.
Secure folder and dualapps make different googleplay services when you create them which is like having two phones at the same time... I wonder if those are the issues

I do have goodlock. Only the custom clock mod.
I have approximately around 80 apps installed (including the stock Samsung ones)
FHD+ because if the display is barely distinguishable at QHD as opposed to FHD+, you may as well save as much battery as you can while still having the same experience.
I used SmartSwitch when I initially came from the Oppo Find X2 Pro and that went smoothly.
Fingerprint scanner is constantly active.

HEY GUYS, i included everyone to get the last feedback from you all:
So i think it's getting better this is from 90% to 2% yesterday to today, with 6.15hrs of SOT and ~19hrs of Batterylife, BTW i ran 3dmark (slingshot) and androbench and tried new games too so it was fairly more than normal usage ;
I disabled AOD and fingerprint always on, deleted Smartthings and cleared Play Services cache also i did put 265apps to regular sleep.
Things that i didn't change were: The wifi was alwasy on, bluetooth was on for the majority of the time too, sync on, WQHD+ 120hz, NFC on, and since there is no reception here i put the phone on Airplane mode i still have my goodlock mods and secure folder stuff there too.
And about the SMART SWITCH, I just want to show you guys that i only moved my media and contacts/messages to the new phone and not the settings.

So I always used tap for AOD (with option for fingerprint sensor to show when AOD turns on) as well as a routine for AOD always on when charging, best of both worlds and its an unnecessary drain in my eyes anyway.
I was worried at the battery life I was getting (had the phone from the 28th) but does seem to be gradually improving. I also removed GSAM and Accubattery so I wasn't constantly checking (and they run quite heavy in the background, like 500mb between them).
The other thing to remember is when people are showing battery of over a day, there's like 7-8 hours where it just idles loses 3/4/5%, so the battery life isn't really much better, so 24 hours of usage with 6 hours SOT really isn't that different to 18 hours with 6 hours SOT
Hopefully the improvements keep coming, honestly I'd delete the battery tracking apps and just use the in built one seeing as there isn't a clear drain from anything, you'll stop worrying and checking it all the time, thus saving more battery lol

I'm running on Pie with the factory load for Device Care. That may work well for you but not on the software I have.
I do best with all power management disabled.
Android Services battery use went nuts with power management enabled... and it got worse not better as the days progressed.
With AOD always on it uses less than 1% @ hour for my 10+ so I leave it on.

i had that AOD option since the beginning and some on the other forums wrote that they had improvements after disabling AOD so i disabled that and fingerprint (which is almost useless since i dont need it to scan constatly when im not gonna unlock with my fingerprint anyways i use my mi band as my smartlock)
also i had to use GSAM since i didn't full charge it to prevent degradation and only charged it to 90% hence why the stats are only for 88% of usage. ill delete it after i get another full usage statics. wish the system battery tracker monitored the battery since UNPLUGGED and not since FULLCHARGE.
my phone is getting better imo, and less 1~2hr less than other guys is kinda acceptable since i know NOBODY has that many apps as me lol and also nobody uses both securefolder and dualapps as much as me too.
i really push my phones to extreme and if this one could get me around 7hr of SOT with my usage ill be happy,
but i still think that a software update is indeed needed for Exynos models
The Exynos model really needs a Firmware Update....

Try Gallaxy Labs Battery Tracker, that's all I use most times.
I never use the fingerprint scanner.
AOD was never an issue but Goggle Backup Transport, Framework and Google Play Services are.
Those can cause excessive usage when on AOD on my setup. AOD battery usage should be around .6-1% @ hr max.

So i got my S21 Ultra a couple of weeks ago and the battery life isn't as good as people tell it to be... I wonder if this is normal or i have a faulty unit
Important: i am running the latest update on my exynos device (february security patch as of the making of this thread)
What do you expect? You have used the phone almost 12 hours, used Samsung Music for nearly 8 hours and still have 78% battery left lol. This is great.

The SoT is pretty crap i can only get 5 to 6 hours if i'm lucky, all i do is watch youtube and netflix and nothing else pretty much, and since SoT is pretty important to me idk if i should wait for an update or get another unit
If you are comparing to a Chinese phone, I would agree that the battery life is not great. Before buying S21 Ultra(exynos), I was using Mi 10T pro. It has better battery performance than S21 Ultra. The other thing that I dislike about would be the heat issue on S21 Ultra. Its horrible.
SOT is only one measure of battery life, the battery still depletes when the screen is off, especially if you're doing something like listening to music for 7 hours......
If you saw the YouTube 'battery drain' tests, the majority are in a room, mobile turned off and on WIFI. They are in constant use with minimal ramping/up down of the processor as they only switch apps every hour. These guys achieve up to 9 hours with constant use in optimal conditions.
If you extrapolate out your current usage you're on for 7 hours with 51 hours total, which is very very strong. People would kill for that endurance
At best you can expect 0.5% an hour drain if you aren't using the phone, but that's if you literally leave it overnight and don't touch it. More likely it'll be between 1-2% depending on usage, so if you calculate you've had roughly 10 hours of screen off, that's about 10% battery that isn't being used on screen on time, which equates to roughly an hour of SOT 'missed out on' if you were just to run the device with the screen on for the sake of it.
If you're truly only concerned about SOT, run a day without music in the background and see the improvement. It's a nonsensical thing to do as that's not how you use your phone, but will get you the numbers you want...
You're also using a high end processor and a large screen with a high refresh rate, it's going to use more juice than a mid range or low end phone. If you send that phone back, someone else is going to be very happy when they get it as their replacement

With my s21 ultta i can easily achieve 10-12hours of sot with browsjng and youtube on wlan with total runtime of 48hours.on mobile data its a good 35% less (also cause of brighter screen outdoors) but Overall its good battery life for me (note im debloated and using Samsung browser with darkmode!!)
I'm doing OK on the battery. Turned off goggle discover on side screen has helped aswell as 5g disabled as I don't have it where I live atm

Put brightness on manual. The display eats a lot of the battery. Try to keep it at 50% or less.
Turn off all animations and use dark mode/dark wallpapers. Junk like tic-tok, fb don't help.

Fb is malware, I don't care who or what's on it, it's off limits. Instagram... no way.
Tweeter just as bad as fb. Full boycott on all that junk until they f-f-fade away
Been using manual brightness control for over a year on my 10+. Occasionally I toggle it on but rarely. Going full brightness will greatly reduce OLEDs finite lifespan. Blue goes first... and the burnout isn't even. If I can get 5 years with just a battery change or two, I want it.
So far between Samsung's and Android's weak offerings I have zero incentive to upgrade hardware or firmware

Remember the night of the long knives?
Think how much easier it be to do now...
Has there been testing on the battery effect of different wireless network modes, including while being connected to Wi-Fi?
I understand that 5G uses more battery, but I'm curious how that is affected when you remain connected to Wi-Fi for all data transfers (using 5G just for calls and texts).
Same question for the other network modes, like LTE/3G/2G vs LTE/2G etc. Or also when you are not connected to Wi-Fi.
I can't help worry that some people are getting bad battery life because they have a poor network signal?
Only rough but very little difference between 4g and WiFi when still, and that's in a location with 2 bars signal. Seems like the phone sleeps better with mobile data on.
It's hard to make a direct comparison with WiFi Vs network, as a lot of the network drain is when moving and polling for new antenna. When looking at signal strength, 4g/5g have the same dBm and 3g/2g have the same dBm, but 4g needs less dBm for a higher transfer rate than 3g, so may use less power over time.
Also I don't think 5g is inherently more power hungry than 4g (I may be wrong), again it's just less available and shorter radio waves, and until now 5g has relied on external modems.
Exactly, I wonder if our S21 Ultra is much better with battery life on 5G, because our SoC includes the 5G modem and it's not external?
My desire is to just keep my phone on 5G while I'm at home idle and the phone is connected to home Wi-Fi. I wonder if there is a battery savings to be had if I switch to LTE while I'm at home on Wi-Fi and the phone is just idle.
