"Android OS" consuming battery [POTENTIAL SOLUTION]

EDIT
I was able to solve my battery issue by formatting my SD card. Something on there was causing the battery to drain 2-3 times more quickly than normal. After formatting, I went from 6-8 hour battery life to around 20 hours with significant usage (Google, Exchange, IMAP, Facebook all on push, 3G+Bluetooth+GPS on, 4G and wifi as needed for extra speed).
Important to note, I am not entirely convinced that the Android OS and battery drain are related since I still have Android OS near if not at the top of my battery consumption screen, but the improved actual longevity is very significant. I recommend anyone having their battery run out format their SD card (and possibly USB storage) and see if that helps (obviously back up any important data first!). Good luck!
ORIGINAL POST
I'm getting pretty bad battery life, and it looks like "Android OS" is consuming most of it. I've rebooted (as suggested in other threads), checked OS Monitor for high-CPU usage processes, but nothing stands out. This is un-rooted, stock OS with no third party launchers installed.
I have a feeling if this issue was fixed, I'd be getting great battery life. This happening to anyone else?
Screenshots show the device at 38% after 6.5 hours off the charger.

if u using a 2.3.3 based rom is normal, that bug is fixed at 2.3.4 and 2.3.5

My device is running 2.3.4.

That's an awful lot of awake time with no screen on time. Do you have things updating in the background frequently? I.e. social hub, Facebook, news widgets?
And not to be too obvious, but is your 4g antenna turned on?

No, I don't. I have fewer widgets and fewer accounts (haven't set up my work Exchange yet) than I previously had on my EVO, which got great battery life.
I've been on Android over a year and am quite familiar with how it works... I'm just unfamiliar with Samsung specifically and unrooted devices and was hoping someone might have a similar experience.

I have the same thing. Significantly more awake time then screen on time, and Android OS eating the battery. Also stock.

Same here too

I had this exact issue and no longer do. Here is what I did and posted in another thread:
OK I hope someone finds this useful and/or can verify. I was one of those people getting awful battery life, meaning lucky to last 8 hours from 100% to 0%. The "Android OS" process would take hours of CPU time. Now it will take up maybe 30 min over the course of the day. Here is the only thing I did between the time it went from bad to good. I changed the wifi sleep policy. It is by default (for me at least) set to never. I changed it to "when the screen turns off" and left it there for about an hour. Then went in and changed it back to never. From the point of doing this my battery life has been great.
I know it sounds strange but it seems to have worked for me so I thought I would share.

I made the change, hopefully it will help, although I'm reluctant since I haven't had wifi on all day and my battery has been dropping like a rock. Here's hoping... will report back if it helps.

I rarely use wifi as well but this setting seemed to affect the phone in general, if your using wifi or not. I might just be crazy though. Either way I no longer have the issue so

does the google voice widget pull data in the background or is it a push thing?

I'm seeing high usage (60+%) by AndroidOS also (stock, unrooted, not using WiFi, not using 4G), although battery life has not been bad that I have noticed.
Watchdog Lite indicates that this is primarily due to two processes:
events/0
suspend

battery usage,is it normal?

my galaxy nexus battery seems drain very fast,for standby it goes around 4-5%per hour, is it normal?i have a screen shot here,looks like the launcher eats a lot of power out of it...
by the way, I'm using the Android Revolution HD 2.1.5 ROM.
Could anyone please tell me how to improve the battery? just posted a thread and this took 2% in 2 mins! I'm using WIFI connection...
I tried battery calibration, wipe battery information,still don't get any change...

Firstly 4.0.3 gives better battery performance. That's the main reason I switched from ARHD to AOKP; which also has power saving options to switch off wifi and 3G on screen off. Secondly, I use custom kernels which are mainly tuned to better speed and battery. I can also undervolt the CPU too eek out the extra juice. Finally, minimise apps and widgets that keep wakelocks. Use apps like betterbatterystats and CPU Spy to find the wakelocks and remove those apps.
So yes. It seems your battery drain is on the high side for the usage you describe but don't expect miracles. I'm running a really lean system and I can get something like 2-3% over 8 hours when idle. When actually using the device, the battery drain is, of course, high.

Hi there, thanks for your reply and advice! I will switch to AOKP too. the problem I got was that the phone sometimes loses signal for no reason at all. I will use AOKP and find a better radio baseband. Could you tell me which version of AOKP and kernal and radio you are using? I would love it if I can have my phone standby 8 hrs and only down by 2-3%.

turn off the services you donot need (when not using) - like wifi, bluetooth, data, gps ....
a lower screen backlight also helps
do you have a good network coverage in your area, if not this is the main reason for battery drain
changing network selection to manual is painful when you travel from one zone to another (as you have to manually choose operator network again and again) but it saves battery in cases where network is weak
and lastly - have your battery checked .. could be chances of a bad battery if it is too old

After using cpu spy just check the settings, as long as you're deep sleeping, it should be no more then 5% in 8 hours (probably less)

My phone idle is 4% but Cell Standby is 60% how do i fix that?

These stats don't really mean anything unless you look at the big picture. In general, it seems you may have too many wakelocks not allowing your phone to go into deep sleep. Get BetterBatteryStats and CPU Spy from the market and hunt down the apps responsible.
There are tens of threads in this forum alone that deal with the issue of battery drain and wakelocks so let's not expand this thread. Please search and, if all else fails, PM me.

I'm sorry I have an lte version but switching to 2G only will also save you battery, but of course slower data speeds. If you're on wifi all day then just disable data all together

If you uncheck data that will save you battery power definitely, also you can leave data disabled and still make and receive calls normally. None of this will affect wifi, you will only have to enable mobile networks once you're not around a wifi signal but need data services

[Q] Battery sleuthing - your input is requested

Hello,
I was wondering if you guys would be kind enough to help me figure out what has been going on with my battery lately.. First up, here is all the relevant info:
Phone: Galaxy Nexus GT-i9250 GSM
Network: T-Mobile USA
ROM: Paranoid Android 2.54 - this is based on 4.1.2 - NOT the latest 4.2.1
Kernel: Franco Kernel Milestone 6 <-- My battery issues only started after I switched to this kernel. I had to ditch the stock kernel than came with PA because it was slow as molasses.
Here is the battery drain that shows 43% of total battery was drained in 6 hours

Here are some more details that show how much time the phone was awake:
Partial wakelocks are shown here using BetterBatteryStats. I don't know what AudioOut_2 is but it's sucking down battery. Exchange is another battery hog evidently.. I don't understand why Google Plus is running, I NEVER open the program.
Here are the kernel wakelocks:
Here are the alarms that show which app is waking up the device how many times. LightFlow and Exchange seem to do this a lot. I have no idea why maps keeps waking my phone, I haven't opened Maps once or changed locations but the location service is relentless.
Here is CPU Spy showing that Deep Sleep is definitely working:
Please can anyone help me figure out why my battery drain is so out of control? I forgot to screenshot screen on time but it was less than 30 minutes. You can sort of see this from the graph on image #2.
Thank you in advance.

Bumping this in hopes that someone is able to help me figure this out.

it seems like your signal is fairly bad most of the time, that will drain your battery pretty bad since the device will try to seek better signal.
also, i would suggest you to upgrade to latest PA along with latest franco r361, I see a significant battery improvement after the upgrade.

light flow is keeping your phone awake as well.

Thanks. Yes the signal is not great at my office, but it hasn't changed in the last few months. What has changed however, is how drastically my battery is now dying, this is recent.
I would update to the the new PA with 4.2.1 but there are a few things I'm not ready to give up yet like the old toggles etc. Once the new PA builds some of those older features back in, I'll be upgrading for sure.

Yes it is, I don't know why it wakes up my phone so much. I tried checking the "reduce phone wakes" option, but that seems to miss notifications all the time.
Overall, even with not so great signal and light flow running, this battery drain just seems WAY too much, would you agree?

what is your screen on time?
and light flow has been known to kill battery. id honestly remove it.

How often do you charge the battery? Do you plug it in all the time? Do you run it dead all the time? Your battery may be getting shot out, happened to my wife's to the point it would not take a charge. New battery fixed it. Buy a battery of eBay for ten bucks. Worse comes to worse you have a backup battery if that wasn't the problem. Audio out only took 3.5% and most of the time was deep sleep. I think your battery is dying

I charge it at least once a day - every night. Sometimes I'll plug it in during the day if I know I'm going out in the evening just so it'll be topped off when I go out. But I thought charging these batteries a lot didn't affect their ability to hold a charge?
I'll definitely buy a new battery either way, hopefully that's what it is.
In case anyone else has any other insight, please do share in the meantime.

The screen looks to be the largest contributor to your battery drain by a large margin. I know my GS3 is set to auto-adjust the screen brightness based on the lighting in the location the device is being used. This is a double-edged sword though because in well-lit areas the screen brightness is all the way up. You can turn off the auto-adjust in your settings and set the brightness manually. There are even some toggle widgets out there that allow you adjust between a few brightness settings using a little 1x1 widget.
The GS3 screen is great, but with the brightness turned all the way up I've noticed some pretty decent drain on the battery. I'd start there if I were you.

I get about the same battery life on mine too. I just started carrying a portable charger with me because I got sick of getting 1-2 hours of screen time before my battery was nearly dead. I'd suggest investing in a spare battery or two or a portable charger unless you enjoy having to constantly worry about conserving your battery instead of using your phone how you want.

I really like MOAR but on other roms/stock, I get about 17 hours+ of usage time with about 3+ hours of on screen time. So I'm not sure if its MOAR that causes the huge battery time or if its my ktoonz settings which is underclocked to 1242 MHz using gov. Ktoonservative and sio as the I/O

You have a few large chunks where the phone is awake but the screen is off. Usually that indicates a wakelock of some sort. I would download Better Battery Stats (search for it on XDA it's free for members). Let it run for a while and see whats causing the wakelocks.
Could be apps running in the background. Also i see you have good service in your screen shot, but if you travel into poor service your battery life will suck. You could also try a different kernel.

Some typical things that will cause bad battery life or lots of wake locks: Facebook sync/notifications (Turn them off!) Unless you absolutly need to know when someone post something every second.. Email sync times.. (if your using it, change frequency from 15 min to Every 4 hours or something. When it syncs its running that app, Data and all that goodness. Greenify works wonders! Use this app to hibernate your apps after you open them (Works on non system apps) Have been using for a long time. Other things are like Weather refresh, If set to update every 15 min.. again your going to get wake locks. Screen time out, Set to lower number so it'll auto turn off after 15-30 seconds.. if you need more just touch screen. Usually helps.. I can see typically 2.5 Hours screen on with over a Day on MOAR. (Moderate use.. Once i'm home it's sitting on my counter and not being used till the next day) These will help some with battery life overall.

Some typical things that will cause bad battery life or lots of wake locks: Facebook sync/notifications (Turn them off!) Unless you absolutly need to know when someone post something every second.. Email sync times.. (if your using it, change frequency from 15 min to Every 4 hours or something. When it syncs its running that app, Data and all that goodness. Greenify works wonders! Use this app to hibernate your apps after you open them (Works on non system apps) Have been using for a long time. Other things are like Weather refresh, If set to update every 15 min.. again your going to get wake locks. Screen time out, Set to lower number so it'll auto turn off after 15-30 seconds.. if you need more just touch screen. Usually helps.. I can see typically 2.5 Hours screen on with over a Day on MOAR. (Moderate use.. Once i'm home it's sitting on my counter and not being used till the next day) These will help some with battery life overall.

I have greenify running. I have Facebook greenified. I have email sync off and weather refresh set to every 6 hours. Sync is off. Screen timeout is set to 15 seconds on lowest brightness. Ill try better battery stats to check for any wakelocks.

Sudden Major battery drain on Note 4!

I took my note 4 off the charger this morning and used it for about 1.5 hours (no videos, just tapatalk and Web browsing) , and the battery went down to 73%. During this time I also noticed that my wifi toggle was turning off and on for no reason. I don't have smart network control check on.
Then I went about my day and set my phone down, asleep, and didn't touch it. At 11am I hear the "low battery" beep. I go over to my phone and it's at 5%!
My battery has never been this bad before, and this just started today with no app changes. As I'm typing this, my phone went from 20% to 16%.
Is anyone else experiencing this issue (both wifi toggling and battery issue) and know a fix? I've attached my battery graph from today.
Edit: It looks like the phone was "awake" all day today except for the time it turned off due to low battery. Also, it looks like Bluetooth is using way more battery than it should be.
Thanks!

So I found the culprit for the wifi. I have a tasker profile that turns it off when I'm not connected via Bluetooth to my house phone. This means that there is something wrong with my Bluetooth. Nothing has changed with my house phones. Any ideas on the Bluetooth?

Try getting rid of the Tasker profile. I don't think it's your phone. I bought Tasker and tried to set up some cool stuff but it kept messing things up. I don't use it any more. Android does a pretty good job of taking care of stuff without it.

Thanks that was actually the first thing I did when I found out it was a tasker problem. I don't keep wifi on all the time due to battery drain (unless I'm mistaken on that?) so I'll have to bring it back eventually. I didn't think android had a "turn wifi toggle on when home" ability.
I unpaired my house phones and I'm going to repair them tonight and see if that helps.

Lollipop doesn't let you toggle Wi-Fi with Tasker anymore w/o root access.

You can still toggle wifi. It's gps that you can't toggle without root.

I've had this happen to me twice including just now hence why I searched for posts on this. Seems like it happens randomly when I stop using WiFi hotspot and I'm at home with my WiFi automatically trying to turn on. I use wifimatic which turns WiFi on when I'm near a cell tower near my home and shuts off when out of range of that tower. My WiFi won't automatically connect if I turn off my Hotspot, so I have to restart. Just twice now this drained my battery from like 30 to 0 in less than a minute. It's not often it happens and I'm home anyhow so putting it on the charger isn't a problem. Maybe this helps but maybe not.

It's been my experience that leaving wifi on doesn't drain the battery very much. I leave mine on. Besides, the quick toggle is very easy to use. Trying to automate it is more trouble.
