Android Usage--Battery Drain - Verizon Samsung Galaxy S 4

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.

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

Click on the android OS. Is it keeping your phone awake for an extended period?

Not sure if it'll show up, but it's eating up 65% of my battery :/. Not sure what's causing it.

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

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.

Do you guys with the high android battery usage have the Verizon ongoing connect to wifi notification? When I had it my Android system was high now that I managed to take it away is gone down a lot

Sudden battery loss after crash

I was playing a game when my phone crashed and locked up. I had to restart my phone and upon restarting my battery is now at 20%. My battery was originally at 85% and I was playing the game for less than 5 minutes. Why did I lose so much battery power in such a short time and is it harmful for my battery? The name of the game is E Warrior

Your battery did not actually lose all that at once, all that happened is either a change in the way battery fuel gauge is bring reported or a corruption of the battery stats being kept.
Either way a couple charge cycles and the gauge reporting will get back on track.

Not even a couple of charge cycles. The fuelgauge should "converge" within 1-2 hours. To make it converge faster:
Turn off phone
Pull battery for 5-10 minutes to put it in a "relaxed" state (no recent heavy charge/discharge)
Put it back in and power on
Also, what was the raw battery voltage? It's impossible to tell whether 85% was a false-high or 20% was a false-low without knowing the raw voltage.
I have left my sgs off for a few hours now and it hasn't made a difference. I just got home and plugged it into the charger and I will wait and see what happens...
I've had the same thing happen to me this morning.
Phone was Idle, full after being charged overnight.
I was checking the web to make sure I had all my ducks in a row before
loading up the Unammed 1.04 ROM.
Tried to wake up the phone, nothing.
Tried holding the power button a little longer, nothing.
I plugged it in and tried holding it longer yet, finally.
Phone crashed itself but hard.
Woke it back up with a heavy dent in the available battery.
Dropped something like 60% over the course of an hour or less?
I was just about to panic.
Added some more juice, while I made my backups and copied in the new ROM.
I'm not sure what that was all about.
I've had this happen recently...

I had this happen once. I plugged it in after the battery level plunged some 50% after an app crash. But as soon as I plugged it in, it seemed like it started correcting itself. The charge level would go up by a couple of % points every minute and converged to the right value within an hour or two.

Happened to me last night. Went from 30% to 12% after a crash/restart. You can see the small bit of red on the right.
So does anyone know for sure if the battery actually drained that fast or is it some kind of glitch?

It is not physically possible for the battery to drain that much that fast. Now in an extreme battery failure you could lose that much capacity, but that were happening your battery would be pretty much shot. don't worry that is not happening to you.
The fuel gauge reporting just got reset and if it was off before it will be closer now. If it is off now, it will work itself back out very shortly on its own.

I would agree with the above. It was annoying but I'm not yet very.concerned. if it happens again or becomes a regular thing then I'm going to be a bit annoyed.
I got my sgs2 2 weeks ago, today I noticed something weird:
I unplugged my phone at 9:15am (100% battery), and at 2:45pm it was at 10%. I am not sure why it died that fast.
I am using some app's which need to be synchronized, but I dont think they can cause this. (FB, Email, Weather). please advice.
How about this usage after installing a new Rom and a theme.
I do think it's the theme I have applied, but it gets too hot too even not being used. I'm not sure what the Rom is, I am using the one the phone comes with.
My phone did this last night for the first time, Ive been catching dolphin browser using a lot of resources. I forgot to kill it last night, battery dropped 50% in 2hrs.
I have removed the theme I had applied and it came to normal already. But I am concerned why it did happen, is it not supposed to support themes like GoLauncher?
Only worry if the problem persisted. Use the battery then charge it full. You likely won't have any issues.

I noticed the same thing with Dolphin browser and if you go into settings and activate the Google or Facebook accounts to be used in conjunction with Dolphin that it will put your phone into overdrive and heat it and drain the battery in about 3+ hours...So I would avoid using this if you like using your phone the whole day!

Is expected to have the phone hot during charging? I am charging it now and it is getting hot even though I am not using it. I am really worried about this.
Please let me know if this is a normal behavior or if it's not.

There's already threads discussing safe charging temps. 50°+ celcius is bad and 70° is deadly to the battery. Phone can handle much more. Download a battery temperature app.

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

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

[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%

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.

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.

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-

I don't have the battery drain problem but I'll try that. Thanks.

Massive battery drain issue, already...

After two days with my S5, I seem to not have found a way to get over a ridiculous battery drain. I'm only getting around 6 hours of use with ~2hr screen on. (Right now it's at 13% battery after 5hr 42min with 2hr 9min screen on). From what I can tell the primary culprit, as usual, is "Android System" which is using 24% of the battery as of right now. Thanks to KitKat, I can't use WLD to figure out what the drain is. Has anybody else had this issue?
I've tried calibrating the battery (drain to 0%, turn off, charge to full, etc), force stopping clear cache and data on Google Play Services/Play Store/Google+, turning off WiFi, location, etc... nothing seems to work.
Further, no matter how much I clear/end all apps and whether or not I use a downloaded app or the built in task manager, I cannot for the life of me get the RAM usage to go anywhere below 1.32Gb.
Note: Yes, I accidentally posted this in the General forum first, been a long day and clicked the wrong one, I've already requested that the admins delete the other post.
UPDATE: I think I might have narrowed it down to "AntService" under Android System, but I have no idea how to fix that...

I have had mine for only a day and YES, I notice a quick drain on the battery. No clue why
That's weird....I'm at 46% right now, 14hours 42min with 2hours 22min of screen time. I also don't have AntService. I did take the update yesterday it was for System Stabilization, I wonder if that has something to do with it as well.

I had taken the update too. I did a factory reset, uninstalled Lark (figured maybe it was hung looking for ANT+ devices), and did another deep charge/calibration. Unplugging now, we'll see.

Let us know what you find. I think it's probably something you installed though and not the phone. Mine lasted 3-4 hours on most of the time while I was playing with it/taking photos at full brightness from 60%. I updated it as well.
Full 5 hours 10 minutes of Screen Time and 17 hours turned on today, this playing and still setting stuff as I got it yesterday. My S4 before Kit Kat was giving me constantly 4 hours of screen time on same daily usage, with normal battery stats showing Screen wit 50% of usage and the other 50 well spread, after Kit Kat at most 3 hours, and the same issue with Android System been equal or some times even greater on usage than the screen.
But, so far I'm happy because even when I used it today a lot different than I use it in a normal day it still managed to gave me over 5 hours of screen time, that's great for me.

Solution herehttp://forum.xda-developers.com/showthread.php?t=2721378
Just drained my battery completely (a full cycle of fully-charged to fully-empty).
With an average usage, about 80% running on Wifi (with wifi calling), about 30% screen on, two calls of total time of 30min, internet browsing, 3 gmail accounts pulling gmail regularly - Overall - 34.5 hours.
BTW, I love this new battery-charging animation when the device is off - a liquid green energy flowing from the USB into the battery, bubbling and filling up my battery - cool
EDIT: Full charge from 0 to 100% in about 2 hours. Device was shut down during the charging period.
I've gotten over 21 hours and 6 hours of screen time. You should try turning sync off, but it definitely sounds like one of the apps. I doubt your battery already has failed damaged. Also battery calibration is more of placebo effect, it doesn't do anything. When you fully charge your phone it does the same thing as those apps. Don't worry about Ram going under a certain number, unused ram is wasted RAM. Worst case scenario just factory reset start over.

I did a real calibration, not those stupid apps, and I tried factory reset twice, still no fix.

Do you have leave WiFi on or have WiFi calling enabled? I have found my battery drain with the screen off and WiFi calling enabled be a bit less than 3% an hour. With WiFi disabled and my phone connected to 4g my battery drains at under 1% an hour. With the phone connected to 2g networks the drain decreases even further.

Well I'd been doing great since I got it. Left my phone at home at maybe 70% and went for a run, came back an hour later and it was at 35% with Samsung Quick Connect taking up 46%... weird.

Standby drain

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.
