"Android OS" drains battery - Nexus S Q&A, Help & Troubleshooting

Hey folks,
i am using Oodie's 2.7.6 MIUI rom and the air kernel v4.4. i am experiencing a rather annoying battery drain. the phone has been running ~15h on battery and is at 63%, however I haven't done anything with it except for checking FB once.
The phone is UC and UV (100-880mhz, voltage all down at least 25mv). according to the battery monitor it seems to be "android OS". how can i figure out which process exactly keeps on draining the battery?
push notification is active for three apps (google mail, kakaotalk - sth like whatsapp, facebook).

37% in 15 hours is roughly 2-3% an hour. You're probably not going to get better battery than that since that adds up to roughly 40 hours of standby which is very good batter life. Android OS is at the top of the list because nothing else is using power (it's a relative statistic).

Most definitely. From the looks of it, you barely even used your phone.

this is exactly my question. the battery drain wasn't this bad before. Even with slight to normal use i could go around 30+ hours without recharging. now the battery is done in the same time without any usage

i had that on quite a few ICS ROMs myself... turning auto rotate off fixed it for me, maybe it does the same for you

Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?
I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.
Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.
This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.
I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU
This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though
when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.
Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.
Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....
Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.
i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.
If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).
W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....
What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.
At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

Foyo update...Battery life shortened ?

Has anyone noticed their battery life seems shorter since the update ? I installed the official froyo update last night and it seems I'm running out of juice much quicker than before.
At first mine ran down faster. I ran it all the way down. Charged it. And ran it all the way down again and charged. It seems back to normal.
I didn't have any issues. Maybe you changed something else as well? Could always try a few recharge cycles and see if it stabilizes..
I was running the leaked 2.2 and I flashed to official 2.2. My battery life is almost double what it was. I can't complain one bit about battery life, although I have other gripes with the official Froyo release.
I'm with icepop on this one.. I was running the stock rogers rom pre-update and now with the official rogers 2.2 I'm getting at least double the use before having to charge again.
I'm having battery issues with the new stock Froyo. I lose a huge amount of juce when in standby. I thought I may have my widgets updating too often so I charged it up and put it into airplane mode last night. The phone lost about 1% per hour in airplane mode. IDK what is normal but that seems like a lot to me. I didn't have any apps running, except my alarm was set for the morning.
I have SystemPanel installed and my cpu load NEVER goes below 10 percent, even in airplane mode. I suspect this is a large part of the issue. In app history, system and system processes are always on the top of the list and are around 3% each. IDK what controls this or how to lower it. I would love some feedback from someone else with SystemPanel just to see how our numbers compare. Overall the battery life I'm experiencing is pretty terrible and a buddy of mine's Fascinate has much better battery life (hence something must be wrong somewhere). He and I were skiing all day over the weekend and when we got back to our cars, my phone was half dead and his had lost almost zero juice. This displeases me.
mine's was better actually. but i didnt stayon it for long
My initial results with 2.2 were very bad (10% drop per hour when idling). I reset the phone back to 2.1 then re-installed 2.2. This did not help. Now I did this again (2.1 then 2.2) but this time I have not re-installed my apps and have not rooted (yet). So far, battery life seems to be normal. I suspect that some of my applications might mis-behave when installed on 2.2. I am planning to add them slowly and watch the battery.
Not here, seems the same to me
Mine is terrible ! I don't know what it might have been on 2.1 as I upgraded fairly quickly. Essentially I charge all night and then disconnect from power at 6:30am and then by 4:30pm I'm out of juice (phone shuts off). Any ideas here? I'm not running anything extravegant (email only) and hardly make any calls.
Whenever you flash to a new ROM, wait for at least a week of normal usage before you judge the battery life. The reason is simple, your battery stats are reset after ROM flash and your new OS needs time to learn how your battery drains before it can give you accurate readings.
If you can't wait for that long, you need follow the battery calibration thread to force a manual calibration of the battery.
I'll give it a week and see how it is then. Definitely is draining much quicker now though. I think It acted similiarly when I first got the phone as well. If I recall correctly the batter life sucked when I first got it, but then a week or so seemed to get much better.
I did the manual battery recalibration (let it die, charge while off, turn on and bump charge...etc). Last night I lost about 2.5% of battery per hour while in standby. This seems improved since calibration but its still pretty terrible IMHO. Is this in line with the amount of drain other are getting or am I draining more than usual?

Running stock since purchasing the Captivate back in August, and so far battery life actually seems to be routinely as good if not better than 2.1. I must admit I didn't use my phone a huge amount yesterday (except for about an hour plus of downloading a bunch of wallpapers off Zedge for some ungodly reason lol), and after 18 hours of the phone being on I was still over 50% battery life left. 2.5% in standby doesn't sound like all is well - you must have something running in the background or similar issue. I have a live background, sync 5 e-mail accounts (granted, only one of those is every 15 minutes - the others are every thirty minutes, every hour, and once a day on two of them), and with light use I am getting over 40 hours with 2.2 so far (about in line with 2.1, but seems maybe just a little better). Heavy use I am dropping more like to the 12 - 18 hour mark (heavy use for me means the screen on more than off, actively playing games or using apps, large amounts of texting, etc. Solid game playing I haven't figured out a drain yet, but on some games it seems like I can drop almost the whole battery in close to 10 hours). At your rate of 2.5% per hour in standby you would only make it forty hours without even using the phone. I have been using mine just a little this morning (FB check, logging in to one of the desktops at work remotely to make some changes, live background running, WiFi sleep policy is set to when screen is off, but to be honest that is about it) and I haven't moved off the 100% mark yet and the phone has been unplugged over an hour and a half.
All that said though, as other users have stated you might want to give it a little more time for the system to recalibrate the battery usage. I would definitely check your processor usage though regularly to see if anything seems 'off'. One thing that caused me problems was that my SNS service would be running but then would get stuck in a pattern of 'Restarting' - would drain my battery rapidly.
It has been said that bettery drain is not linear. First 5% goes real fast. So, you need to judget the average over a day of use, not first hour or so. I'm still in first week of ROM flashing. So I can't confirm anything yet.

Battery drains unusually fast while screen off?

Last night before I went to sleep the battery was around 94% after an hour of solid use from a full charge.
I woke up today about 9 hours later and the battery was at 55%. It's been about two hours since then and I'm all the way down to 30% with only about 20-30 minutes of solid use.
What's up with that? Any ideas as to what I can do to fix it?

-Battery calibration, basically drain to 0%, then back to 100% on single charge.
-Try custom rom
-Might be radio, try flashing different found in development thread
-app or widget installed recently?
-look in battery use under settings menu to find what is eating up battery consumption, in your case likely something via cpu consumption (ie not display use)
What is your current set-up?
Check out battery drain threads in general section.
I'm working on battery calibration right now, this is my first day with the phone (I got it about 24hrs ago, actually). I'm gonna let it die then charge it to full.
I'm on a custom ROM right now, QuickWiz v1.0.3. It's blazing fast, no cool features though. I miss my CM7 that I had on my Inspire but the CM7 alpha was a bit too buggy for me.
I'll check into flashing some other radios in a few and I suppose it could be the weather widget I installed. I'll check that and see if it's syncing too often or something.
That's the funniest part. I just looked and I have 1h51m of screen on time (Mostly around 35% brightness, give or take a bit) and it's taking the majority of my battery at 31%. Right under it is Dolphin Browser HD at 13%. I might just swap to another browser, any recommendations? Last under that is the Android OS at 12%, then everything else is under 10% - Cell Standby, Speed Test, Market, then down to 5% which shouldn't matter.
are you using a cpu governor such as system tuner or setCpu? if you are OC'd, id suggest also cpuSpy to determine how long your device is in each state(clock speed)
I am OC'd. i have a setcpu profile for screen off that cuts it down to ~54/400MHz when the screen is off, set to conservative as well.
Hmm, if I had to guess, check the radio. I've had the problem before. As far as browsers go, I like Dolphin HD, just make sure you completely exit out of it when not using, otherwise it can be a resource hog on idle. Since you haven't had the phone long, reflash your rom of choice too if you get such a drive, that has fixed battery issues for me also.
I love my battery life using TPC's ROM with DaG's kernal. I'm also using TPC's CPU zip to govern and set CPU speeds 192-1782MZ without the use of third party programs. Some see zero battery loss when idle over night. I lose maybe 5%.

I installed a new radio with 8% battery left before I went to a birthday dinner. That 8% lasted me through light to moderate use at the dinner for about an hour and a half before, and I got back with 3% remaining.
I also froze a bunch of bloatware which could have also been taxing my battery. I'll wait another few days of use before I flash any other ROM's/Radios to make sure I'm not happy with the battery life and past that, I guess I'll just have to return it for a new battery or an LG Nitro HD instead, if the dev scene starts to pop up for that phone.
Can you link me directly to the CPU script zip?
what was the radio???
I just got the QuickWIz a few days ago and Im having the same battery drain problem while screens off.. its getting on my nerves

Battery Problem

Hey Guys
i have a strange Problem
my last one plus one had a good battery life time but the sound buttons get brocken , so one plus change my mobile.
1 wekk ago i get my new phone, everything is working but the battery drain was very fast.
i decided to install blisspop with bueffola kernel tweaked it a little bit for battery saving and install BBS for wakelock detections.
I elimenate all the wakelocks that cause a fast battery drain and since that te battery drain in idle is minimal but when my mobile phone is on the battery drains 3% in 1 hour.
That's weird cause as i say i eliminate all the wakelocks that causes fast drains and use the phone most time for spotify and whatsapp.
And if i start to browse on the Internet the battery life drops even faster
So what can i do?
Am i do something wrong
or is the battery of this new phone crap and i'm so luckily to get a phone with a failiure battery?
Any suggestions would be nice and sorry for my bad english.
German or russian is better
on 50% battery i have something like 2h of screentime so i thing till 0% battery i will have 4h SOT and this is nothing (don't use the Phone much a saing above only whatsapp and spotify)
Well, to be honest, 13% in 4:30h is not "very fast" considering you had 30 minutes of screen time. Mine loses about 10% per 30 minutes of using the device, going by that there are only 3% unaccounted for which easily fit the 4h standby your device was in.
Anyway. In 4:20h of tracked time, you have 1h awake time of which you had 35min of screen time. The remaining 25 minutes can be split up in roughly 15min of AudioOutput and 10min for several wakelocks such as the proximity sensor doing stuff for 3 minutes, the phone doing stuff for 4 minutes, basically everything is accounted for. All in order I'd say.
What I spotted:
You are on Lollipop. Did you wipe after/before upgrading to Lollipop or did you dirty flash from CM11s?
Do you have the new Lollipop-compatible firmwares (they come with CM12) installed? Not sure they come with Blisspop.
BetterBatteryStats has the CPU sitting on 1500MHz for half an hour. Check whether you configured your system to stay at 1500MHz with screen on which of course would be crap, the CPU should idle at around 300MHz.
It seems you had the device shut-down and then booted. Booting up the device eats massive amounts of juice.
Android reckons 3 days of usage like that, what's not ok with that?
1. Yes i wiped it and don't dirty flash the rom befor i was going to lollipop
2. Not sure have the latest bissplop
3 Where can i check what i configured to stay at 1500MHZ , in the kernel settings?
4. i know i rebootet it once
5. The reckons of the 3 days is not true , it only affects if my device is staying in standy cause i lost nearly nothing (as you will see in the logs i posted in the spoiler.)
The first BBS log shows the Device fully charged at 100% with wifi and Mobile Data on. I left the Phone in standby for the night (8h) and i didn't lose any precent.
So after 8h standby i still have 100%
After 11 o'clock till now i used the Phone mostly for spotify , a few times Whatsapp and something like 30-50min for internet.
In the second BBS log you will see that i lost Bat.: -35%(88% to 53%) [4,5%/h] although the SOT time is only at something like 2h.
The SOT time of 4h would be total normally for me if my reckon of android would be 3 days cause this is the case on my lg g2.
Because i use the phone most of the really only for spotify.
So the main problem of my device is not the idle drain but the drain if the screen is on or spotify works in the background with screen of.
I hope that the BBS logs in the Attachment and the 3 pictures can help you.
Thanks for your help
Don't go by the sudden drop of battery percentage after staying in standby for a long time, eg. over night. The very subtle decline of the voltage over the course of the night is smoothed out and reported as 0% lost. Once you start using the device, and the change in voltage gets more noticeable, the situation is re-evaluated and the previous drop of 0% gets counted in and a sudden drop of several % over a short amount of time will occur. This is physics and by design.
As for the rest, I'm by no means a pro in reading BBS Logs but from what I see, yes you are on Lollipop firmwares/baseband so we're good. The device enters deep sleep just fine, excellent in fact. No major or irregular wakelocks seem to occur, perfect.
As for the daily usage log, I see 7:45h. Of which 4:10h in deep sleep and 3:35h awake, of which ~2h screen on and ~30min phone on. You lost 35% in that time, averages 4.5% per hour. This seems perfectly ok. This would translate to 7h awake time with 4h screen time. I seem to fail to see your problem.
Interestingly the frequency tops now at 1500MHz. Did you change something?
To take myself as an example, on my way to work, I lost 19% in roughly 45-50 minutes of playing ingress. I had about 45 minutes of screen time, GPS constantly active and of course constant data traffic. I arrived 2h ago, barely touched my device in those 2h and lost another 2%. This is more or less in line with your usage, 1-2% when sleeping, 4% when awake with screen off, ~20% with screen on. You're not happy? You reckon you had more on your previous device?
Thanks for reply and help
My goal is to have a few days with android e.g 2-3 days
SOT is not so important.
Important is that there is not hudge battery drain wenn i hear spotify cause it dosn't mather if the screen is on or off it drains hard
On my lg g2 it's not so hard
And no didn't change anything about 1500MHZ
Any suggestion ?

Wakelock battery drain [Need Help]

Hello, guys!
I have a problem with my phone for the past few months and after clean flashing 7.0 Nougat it's still present.
My problem is that when I'm home, my phone drains not even few percent of battery. Specially when I'm sleeping, I can go to bed with 100% battery and wake up with 98-99%. BUT when I'm out, specially when I'm working since my work involves a lot of walking the battery just drains like hell and I mean like 7-10% per hour considering I don't even use the phone. Sometimes I will have 30min to an hour of screen-on time and after 10 hours of work I will be home with 15% of battery left.
Now I know that this is mostly to some rouge app that keeps my phone awake and drains my battery but I'm not really sure how to pinpoint it.
I will provide my stats from Bettertbatteystats and WakelockDetector if you guys can help me.
Thanks in advance!
Edit: I just want to explain that the straight line on the first picture with the batter drain graph is when I went home and left my phone on the table for about 3 hours. You can clearly see that the difference in battery consumption during my phone being in my pocket and on the table.

Maybe you are in a poor service area when you're at work, poor signal drains battery pretty quick because the device is constantly scanning and searching for better signal.
Or
You're using one or more social media apps such as Facebook, Facebook Messenger, Whatsapp, Instagram, Snapchat, etc.. These apps are constantly running/scanning for notifications and are well known for eating battery, especially on mid-low end and older devices because they don't have enough CPU and/or RAM to keep up efficiently. Judging from your screenshots, I would say that this is your issue.
