Standby drain - Samsung Galaxy S7 Edge Real Life Review

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy S7 Edge's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

sleeps like a baby, 0% drain on 8h sleep.

10% drain for 8 hours (but I had my enabled the "Always On Display" to Show the Time)

2-3% overnight for me. AOD off.

I had been having an issue where mine was never entering deep sleep. I tracked it to two things. Google voice recognition on every screen and auto backup. Once I turned those off, the battery drain seems much improved, although I only made those changes this afternoon.
If you're having issues you might try to identify the wakelock via ADB. Run the below code in a loop and see what pops up. It worked for me.
adb shell dumpsys power | grep -i partial_wake_lock

That being said, I sure miss having root to run BetterBattery Stats. . . . Sigh. . . .

sorry for the stupid question: does S7 Edge enter deep sleep automatically?
I am having a serious battery drain issue in standby. I did just turn off my google voice recognition on every screen (thanks czucker) so I'll see what happens. Im kinda upset with the performance though. I picked up the phone on Tuesday from my local sprint store (pre-ordered and it came in early) so maybe the phone is still learning my usage patterns but still the standby battery drain is concerning...

I fixed standby drain by turning off NFC and set OneDrive to only upload when charging. Donno if thats your problem, but its my best tips since it worked for me

You will find voice recognition in the Google app under settings/voice/OK Google. The second one is in settings/backup and reset under samsung account.

In my first full day with the S7 Edge I was not super impressed with the battery. From 7am to 9pm, from a full charge I ended the day around 10% with very minimal. Maybe the large screen takes up more juice than I thought---I was expecting the larger battery to last me quite a bit longer. Coming from the HTC M9 and that battery ended my day around 30%.

Thank you! After a few days usage, still not getting good battery life, usage time is around 11-12 hrs, the battery drain appears to be android system. I've turned off almost all apps from notifications and auto updates. Reading other posts the exynos version is getting great life. The 820 and Android system aren't playing nice...

drained overnight
I fully charged the phone 100% before bed. Next morning, 8 hours later battery down to 12 % with android and screen sharing the usage. Next day I resetted the phone to uninstall all my apps and tried again - still almost same result. Is there anything I can do to investigate this? I have turned off Google Voice and Automatic Backups already - the huge battery is performing worse than the htc one m7 i replaced
Any suggestions?
Edit: Should have mentioned - the phone gets untouchable by morning! hot as anything - i guess i should be contacting Samsung

No suggestion. It is best to contact Samsung, as this behavior is not normal. These phones are made to be used, and not for us to turn off almost everything just to get through a day.

Thanks for the ADB command. I'm showing "AlpmModeManager" as a "Doze_Wake_Lock" (I modified the grep string a bit because partial wasn't giving any hits)... Any idea what that is?

Guess when I tuned off the AOD xD

Guys if you have Quick Tools enabled as one of the Edge tools, try disabling it. This is what I just noticed:

All apps that are part of android system report this percentage.

Had an issue with the "Pocket" app. This awful crap drained almost 10% of my battery and I did not even used it (I did not setup the app and did not opened it.. not even once..). All good after I uninstalled it.

New S2 user - horrible battery performance?

I got my S2 a few days ago and flashed Cf-Root and the latest checkrom a couple of days ago. I knew battery life was a big issue with S2 so i thought i'd check how mine was performing.
I left the phone charging through the night and after unplugging the battery is down to 80% after just 5 hours. What makes things worse is that the phone has been unused for about 95% of that time. All i've done is send one SMS and flick through my settings a couple of times.

Display being 44% is puzzling since its only been on 30 minutes at about 50% brightness. Android OS is 39% and when clicking on that it says it has been used just 22 minutes (CPU total).
I a real S2 and Android noob so i really have no idea whats going on. This cant be normal surely?

Your display has used 44% of the power used = 20% total so your display in five hours has used about 9% of the battery .
Search all the battery posts and read them for clues .
Start with Better Battery stats thread .

Try siyah kernel 2.1.1 version. Its been the best for me
I've installed Better Batter Stats although i dont really know how to use it and interpret the information. I've included some random screen captures in case they're important.
Heya, I see that you have WiFi on pretty much and that's quite a battery drainer. It shifted my battery consumption from 1-3% while sleeping to a whooping 25+% (about 6-8 hours of sleep)... make sure you turn off wifi and data services when you're not actively using your phone

If i turn off wifi and data when not actively using my phone wont i stop receiving various updates and such? Is it normal for people to have turn off wifi and data when not using the phone?

Yeah, but you can get them when you use your phone again. I can't speak for everyone but I never have wifi on while my screen is off, it wastes battery and I don't have a social life/need to keep my Internet on

After doing some reading one thing that may be causing this is not calibrating my battery.
When i received the phone it came without about 60% of charge so i just plugged it straight in to my PC figuring i'll let it charge to full while i play around on it. Unless i'm mistaken this was a bad thing to do?
I've downloaded Battery Calibration from the market and i'm currently waiting for the battery to charge to 100% before running it. Hopefully it'll help things.

The best way to calibrate the battery is to actually charge to 100% (make sure the phone is off) then unplug the battery for about 90+ seconds, then plug it bin and use your phone normally until the battery is depleted to 3-7% then charge fully. BTW I HIGHLY doubt that's the PROBLEM.

So once i've calibrated the battery and find that that isn't the problem how do i go about investigating what is the problem? I'm far too much of a noob to work it myself
I'm considering flashing back to stock firmware and seeing what happens with that.
Reading numerous threads on these forums I've found out that there is absolutely no need to calibrate the battery in SGS2 with any external programs / processes. The battery calibrates and maintains itself during its lifetime (something about a controller chip being integrated inside them).
If I may recommend, flash SiyahKernel , apply the battery optimizations through CWM (install zip from sdcard), and just work normally with the phone for a few days, making sure you remove all unnecessary applications and turning off data services whenever you don't use the phone.
And if you still get about a day of battery with moderate usage, it's very good for you... the stock battery just doesnt live that long with the powerful hardware that is in the phone

Android Usage--Battery Drain

My battery is quickly dropping according to my battery stats it's android usage. I did a search but only information for the SGS3 pops up. Anyway I can find out what's causing it?

I'm having a very similar issue. I thought that screen was suppose to be the largest drain, but Android System appears to be consistently 55%+ of the battery used.
mine usually doesnt go above 20%..
its on screen percentage that is killing me lol
I wonder what's causing it.
My main usage on my S4 is the screen.
LOL Tap in the Android System in that list and see what all is listed under it. If you are running everything that Samsung added to the TouchWiz like the air view and eye tracking and such you will have the System draining your battery. Find out what you will actually use and not use and what is more for play turn off and what you will use regularly leave on. My guess is most ppl will have most if not all of it off on a normal basis
My S4 i got today from VZW i had some gestures on charged it to only 74% by noon (had to go out) and 5 hours later with just under 3 hours of screen time i was at 63% battery still and screen was 65% in the list with Android System at 12% Also screen was at 35% though not at brightest level.
Eric
Mine is showing only 5% over today. Screen is my biggest drain (as expected). Does it remain high usage after reboot?

Oh ok. That's what I was confused about. It was fine yesterday and then today not so much lol. But I did disable some of the gestures to see if that makes a difference. Thanks

a little update. I have seen this as well now but only after charging to full. It was not doing it yesterday cause i didn't get a chance to charge it to full until later last night. I was in and out since picking it up yesterday morning and never got it past 80%. So here is what i found.....
Once full and I unplug the phone (from the wall not usb charging obviously) the Android System is in the 50%+ of battery consumption in just a min or 2 from unplugging and seems to stay there. So after a few times of letting it get to 96% or so and recharging to check after an FDR I decided to just unplug the phone and reboot right away, the Android System never gets above 9% in the battery stats list when i reboot immediately after I unplug the phone.
Anyone with a reason why after charging, something in the list (and it's a HUGE list of apps at that) making up Android System is hanging after a full charge cycle? I mean technically, it's not a bad thing to reboot your phone each day but should you HAVE to do it?
Eric

Unless you are seeing your battery yield horrible life this is completely normal. Because its telling you a percent of the loss, for example your battery is at 90% so its showing you the break down of the 10% loss. So your screen is 70% of that batter loss. The screen is always going to be in the top. Thats good honestly that shows that you dont have any apps sucking down your battery more then the most power consuming hardware (screen)
My Android usage is high too. 60% is weird. I've frozen alot of stuff and only a few gesture options enabled. Would like to figure this out myself

After 3 wipes of device and also an sd card wipe I was still having android system double the power consumption then the screen. I wiped the phone and then didnt log into google and just used the web broswer and surfed for 40 mins and then checked the stats, android system was still the number one even with 40 on screen minutes. At this point I was done with this phone
I just went to verizon, the manager first tried to tell me it was because I have location settings on, then I told him that I had the issues before I turned them on. Then he tried to tell me it was because im not using power saving mode. I had to almost fight for the exchange, he finally pulled out his phone and googled it and saw that this is a known issue and then tried to tell me that because its known that I shouldnt do the exchange and wait for an update, I said no. After 2 hours I finally walked out with a new s4, I will see how this goes.
I too am having the same problem
Sent from my Galaxy S IV
Wow. While this issue is somewhat annoying in the fact that something is there somewhere doing something in the background, it is not something that can be hardware related. It is just something enabled somewhere that we havent pinpointed yet. Regardless, I get great battery life and have just learned to deal with it. I know when some more roms come out and more things are figured out, it will be fixed. Its nothing to go ask for a replacement for. Not trying to sound like an a$$. Just saying
Sent from my rooted Galaxy S4 via tapatalk 2.
tell me this then, if its software then we should all have the same issue, because we are all on the same build (minis the rooted / rom installed) but of the 5 devices that I have looked at only 2 have this drain? I had done a factory wipe and then DIDNT log into google, or samsung so I had only the original installed apps, and I still had the issue,
So the only real way to test it I guess is we need to have someone that confirmed doesn't have this issue they will need to make a ODIN restore and then someone with the issue needs to restore with that, then that will eliminate any possibility of hardware problems.
I see your point. I did find something in better battery stats though. On partial wake lock, there is a process called audioout_2 which had used almost 45 minutes of cpu. Clearly, by the name, it has something to do with sound output and I then realized that touch sounds were enabled on my keyboard. Hopefully disabling that helps. It may not be the whole problem but I'm willing to bet it has something to do with it.
Edit: I checked the cpu time after I turned off keyboard sounds typed alot of random letters for about 20sec then turned sounds back on then typed again for 20sec. Checked cpu time on audioout_2 and it increased that same amount of time like I thought. So I'm going to see if it helps.
Edit again: my android system usage is slowly dropping. From 67-63% in the last 20 minutes. Won't know how much it impacts it until a recharge.

[Q] Deep sleep not deep enough?

I have i9205 for 1.5 week. I rooted it after a few hours I have it. I was in rooted + official rom for a week. Then I flashed Cassies XtraLiteROM to it a few days ago. XtraLiteROM is based on official stripped down to minimum plus some tweaks.
My observation of battery drop during the night (wifi/3g/gps/bluetooth all off) is indistinguishable between the official rom and XtraLiteROM. About 10%-12% drop during the 8-hour sleep.
I greenified facebook app and a few others that I think works in the background. I tried to invoke Wakelock detector, hoping to find something. It appeared normal and said 8-hour deep sleep. The battery level falls continuously and smoothly during the sleep with hardly any wakeup.
Is it common with 4.2.2? I have another LG L9 rooted with 4.1.2. The drop during the night is 1%-2%.
I left my mega all stock. No root or any modifications and when i go to bed i put it in flightmode and it loses about 1% or 2% in those 8 hours just like your LG

I'm also having the same battery drain problems since the first day I bought Mega 6.3. I have tried different ROM versions UAMEA,ED,F2,G3 and now the latest G4 but still having the same problem. Today I lost 3% in a matter of 1.5hours without even doing anything on my phone within those times. Flightmode technique you mentioned seems to be good but the problem is we may not be able to receive emergency or urgent calls/text while asleep. I was hoping samsung would address this drain bug.

But the problem seems to be present even if you don't install anything else than what is supplied !!
I don't understand what's going on with the battery:
one day you put the phone in arplane mode and for 10 hours you eat 1% of the battery :good:
The next day without changing anything you eat 10% in the same conditions WTF !!
As far I can see it seems that there is a problem with the release 4.2 (problem also for the Galaxy S4).!!
In another forum i participate, some people had similar issues, they had been harrowed down to some programs they were running. some people had Mega synchronise their photos every time they connected to the internet others had some other crap going on. if it was a firmware issue, everyone would have it. i, for example don't have this problem. you can try to use Disable service program to see which services are active in the background and are eating your battery and stop them carefully.

From yesterday 23.00 till morning 09.00 lost 11%
From 09.00 till 14:00 lost 4%
From 14.00 till now (23.00) lost 3%
Without touching the phone !!

You've got me all wrong. I'm talking about installing stock ROM (latest version) without any modification i.e. root, cwm, etc and no other apps
installed except samsung built-in apps but still battery drains like hell overnight with almost everything turned-off (wifi, bluetooth, gps, rotation sensor, etc.). So your question is a little bit off topic.

No, not really, because the stock rom is full of bloatware from samsung. I've read reports from other people saying that their camera software or galery or something else, don't remember exactly was uploading their photos to their cloud storage whenever they connected to internet. A lot of stuff can be happening in the background in the stock samsung rom because it's got a lot of stuff in it + the default settings alow synch/backup/downloading updates. Install the light custom rom from this forum, that has everything removed and see how it behaves, alternatively you can use other programs (mentioned one above) to see what's active in the memory of your device and find what's eating your battery.

I've read reports from other people saying that their camera software or galery or something else, don't remember exactly was uploading their photos to their cloud storage whenever they connected to internet. A lot of stuff can be happening in the background in the stock samsung rom because it's got a lot of stuff in it + the default settings alow synch/backup/downloading updates. Install the light custom rom from this forum, that has everything removed and see how it behaves, alternatively you can use other programs (mentioned one above) to see what's active in the memory of your device and find what's eating your battery.

Ok thanks. I will try silentlight tonight. By the way, I received updates of samsung link from playstore these past few hours and among the reason
for update was the battery drain. Also, I'm using an official S View flip cover from samsung. I was wondering whether there is some sort of sensor activated by this flipcase that keeps my mega from deepsleep.

Have a look here, one more idea for you - http://forum.xda-developers.com/showthread.php?p=44428107#post44428107
My battery drain problem appears to be related to "cell standby".
If I charge the phone to battery full, unplug, reboot, screen off, data off and leave it to stand by for a night. "Cell standby" alone takes up most battery usage and battery level drops by ~10%. I can constantly repeat that. I think more users are having a problem with radio.
Reference: http://forum.xda-developers.com/showthread.php?t=2335242
I am trying to disable fast dormancy to see if that helps slow down cell standby drain.
I have to come back @ my comment on the previous page, since today my phone went battery hungry too at night. left it in flight mode during the night as usual but instead of losing 1 or 2% it consumed 12%.
Very strange since the phone should be absolutly doing nothing at all when its locked and in flight mode.
It's not really a problem since im a fairly moderate to light user so i can do 2 days on 1 charge but still.
I also have a strange wake-up problem now, after using the phone a bit and when i press power to lock it, sometimes the screen lights up again after about 5 seconds and goes off again.
I feel worse than it actually is when I feel like robbed 10% of power everyday for no reason. Maybe I was too picky. I have not given up on this. Will continue to look for a solution.
same **** here, today is even worst, 8 hours of phone not doing anything. deep sleeping is at 92% according to BBS, and my battery dropped from 75% to 61%, wonder wat is happening with my phone. damn!
Try this
Sorry. Very bad know English. Solved the problem of the so-

Now 1% per night.

I think that's Maps > Settings > Google location settings > uncheck Access location.
I don't have the battery drain problem but I'll try that. Thanks.

[Q] battery problem

Hello,
So i bought the G2 mini last week and i am a bit disappointed by the battery life. i can't go more than 4-5 hours of screen on time.
The problem ist that "Android OS" and "Android system" are each draining about 19-20% of the battery. Even after a factory recet it is the same.
On the phones i had before these two were about 10 % TOGETHER.
So does anyone know if it's normal?
Thanks in advance
I have same problem.
Did you tried to look what apps is draining your battery ?
It happens without any apps on the phone. Just after reset. So either it is normal or it is a bug on the phone. But i think it is getting better know. I can get average of 6 hours screen on now. But still not normal i think
I have a similar problem. Bought my G2 mini three weeks ago. Seemed good battery life to begin with. Now, intermittently, it's draining up to 2% an hour in idle (just syncing a not-much-used email account over wifi). It's Android OS which is using up the battery, not apps, according to Android's battery information. And it even did this a bit when I tried in safe mode. But sometimes it works great, with very low battery drain. I did a factory reset last night, and the battery drain has been only 3% in five hours. But I'm not sure I trust that it will stay this way. I have a week to decide whether to return it!
(This is the second problem I've had with the phone. Until a few days ago, it would be using 10-20Mb of data a day, which is a big deal when you have a 500Mb contract. Again, it was Android OS that was using up the vast bulk of this data, not me. This behaviour seems to have calmed down a bit in the last few days.)

If it is 4.4.2, then that could be the reason!
Google Built a Bug into 4.4.2!
Hmmmm. let's see on GSMArena. [LINK]
Oh, no! How Horrible!
---------- Post added at 15:32 ---------- Previous post was at 15:31 ----------
The Bug is: AndroidOS-Process eats up your battery.
Mine is 4.4.2.
What's the bug? I haven't been able to find anything about it. And I can't see anything on the GSM Arena page you linked to. Is it a general bug in 4.4.2, or specific to the G2 mini?
Thanks!

As for data drain, just disable data when you don't use it

Battery drain is not for 3g or 4g power consumition. If 2400 mah die with 3g in three hours, what about moto g or other phones...
The problem is fast dormancy. I desactivate it. If you want i can make a tutorial.
With 100% 3g and fast dormancy battery last 12 hours with 1h 30 screen.
With 100% 3g without fast dormancy battery last 48 hs with 4h screen.
Oh rats, this is the 4.4.2 camera bug, isn't it? Only for Qualcomm devices? I did actually know about that bug, and then forgot about it again, and then bought a device with 4.4.2 and a Qualcomm processor. Dammit.
If so workarounds might be: when you use the camera, pay attention to the battery drain afterwards, in case it has activated the bug. If there's a drain, reboot. Turn off the "Smart screen" and "Smart video" settings, since having them on would also activate the camera, which could also trigger the bug. I had those "Smart" settings on until yesterday, so maybe that's what was causing the problem for me.
And in the meantime, cross fingers that LG will upgrade us to 4.4.3 or, preferably, Android L, thereby squashing the bug.

LG had patched that........
3G/4G is very much the reason of all battery drain on my device, today I've gotten alright battery stats with no data connection except for WiFi, haven't deactivated anything but data and used my phone for a lot of youtube/browsing/ chatting. So I believe if you cannot go above 5 hours of onscreen, it's properly due to high usage of camera, or data and WiFi running when not in use

I never had that issue after using camera. You need to check if the process is starting on setting/battery. (That will not start because LG has patched that at least on my country, because I never have that)
I don't know what's going on. Today I didn't use the camera, and the battery seemed fine, and then I took a photo, and it started draining at 1-2% per hour again, so that made me think I'd found the problem. But then I hear it's patched, and anyway if it's the classic 4.4.2 camera bug, it should show up as mm-qcamera_daemon being the process using all the battery, and it doesn't, it showing Android OS doing so. I feel like I'm back at square one, not knowing what the problem is or how to workaround it, and thinking I have to send my new phone back...

Your problem is fast dormancy for sure. I told you that a few post back..
LG comes with fast dormancy activated by default for all operators and some of them dont have fast dormancy so make a fast 3G battery drain. If you drain 2% of battery in a hour with wi fi you can install battery stats and see what app is eating your battery.
I get intermittent battery drain with either 3G or wifi.
But if you could tell me how to change the fast dormancy settings, I could give it a try.
Also, not convinced that it's an app draining battery on wifi. According to Android, it's Android OS, not an app. Or is the Android battery information so not reliable? In that case, can you recommend a battery monitor app?
Thanks.

When Android operating system is draining your battery, is an app on the backgrpuns. You can use better battery stats. Just search in google and will apear.
If Android OS is draining, its common i also have 10% of drain because of that. But it dont drain too much so you dont have to worry. My xperia m2 says android os 60% when idle, but battery drains normal so just dont worry. If you feel a big battery drain use your phine to 100% to 10% and give a sctrenshot of battery graph.
Press thanks button, you are welcome.

Battery life

Any ideas how to extend the battery life? Hardly used the phone today as you can see from the screen shot and currently on 26%

Hi, I'm also using the P9000 for 5 days now.
The battery in standby is ok, but drains quickly when display on.
In my battery statistics, there is no Google Services listed, maybe an update can help you (and also deactivate bluetooth).
I have seen the threads about Eragon custom rom and Rodriguez Mod. Can anyone give further information (maybe some statistics) about the battery life compared to stock P9000_Android 6.0_20160419 ?
Best regards,

I've heard battery life is better with wifi turned to always on and if you turn intelligent power saving to off. Also search for wifi scanning in settings and make sure those are turned off. I keep my brightness set to under 25% also. Easily get a day. I'd loose on average 1-2% on 4G standby. Agreed though as soon as I start to use something more intensive such as Clash of Clans or watch a video where screen is on for period of time battery drains but then how quickly this phone charges up it isn't as bad as it would have been with a slower charging phone.
Increased life with RoDrIgUeZsTyLe MODPACK 1.1
In regards to your question regarding mods,
I was getting about 8-10 Hours battery life out of the stock firmware with my usage. I have since flashed "RoDrIgUeZsTyLe | MODPACK 1.1" which has upped my battery life to about 14-16 hours.
Hope this helps,
-Harry

If you click the magnifying glass in the top right corner within settings and type scanning you should be able to find it. Intelligent battery save is a switch within battery

Guys... Wonder if you guys may have an idea what is causing this. I still have the FP scanner taking 15- 20 seconds from acceptance to unlock the phone. The power button also is unresponsive..Sometimes requiring a hold down of the power button to wake. It's as frustrating as hell.
Anyways.. Playing around with settings.. If I go back into WiFi -->advanced--> keep WiFi on during sleep and change back to never (going against what
was said previously to extend battery life) my FP unlock issue disappears. The phone unlocks instantly.
What would be causing this, is anyone else experiencing this issue, is there a work around or is it a fault with this particular phone.

That's not normal. I'd try backing up your stuff and doing a factory reset. Have no issues with regards to the FP unlocking.

On every rom (even stock ROM) the standby time counts up, If I charge the phone to 100% and leave it disconnected from the charger through the night, it says I have 6 days standby time left the next morning. When I'm using the phone allot, this time is reduced to 4-5 hours.
I don't really know what your problem could be. Maybe an app is keeping your phone awake ( a.k.a wakelocks)? Maybe your battery is defective?
