Android System consuming battery

I have been obessing over my battery stat page and am trying to figure out what exactly "Android System" is. It is usually consuming the highest percentage of battery power. I have tried everything to figure out what action exactly makes Android System get added to the battery stats page. I have disabled everything, every radio, syncing, deleted all widgets. I hardly have any apps as it is. It just seems rather inconsistent because sometimes Ill check the page after making a call and will find that Voice calls has consumed a small percentage of battery and Android System isn't even on the list. Other times I will take it off the charger and make a 30 minute call, but when I check the stats page 70% battery was used by Android System and only 3% was Voice Calls.
Can anyone tell me exactly what triggers Android System so I can make sure I cut down on its battery usage in any way possible

I assume you are looking in the settings > about phone > battery. You can select android system also and it will tell you more info.

Did a battery calibration and now android system isn't the number 1 thing consuming battery as usual. Weird:

This seems to be more in line with what normal battery usage should look like in my opinion.

I had this problem too until I did a calibration. Now cell standby consumes over 50% of my battery regularly, with android system consuming only 2%.

Its still occurring
What would you guys do?
Android system will occasionally use CPU as well, as shown in the following screenshots. Also! My good buddy let me see his Droid x recently. He had 42% battery life left and android system had only taken up 4% of that.
I'm pretty upset about this.

If you asked me I would say all your values are a little screwy. Do you even turn the screen on, on your phone and use it? If you use your phone the Display should be by far the most used. To me it looks like you physically use your phone very little. That is why Phone idle and Android System seem to be the higher numbers.
Guessing you have many accounts syncing in the background. One of the biggies for Android System. So its not that Android System is using so much, the rest of the processes are using so little.

Oddly enough the same thing started happening with my phone recently too.
@Agoattamer
The system wouldn't eat most of the charge in less than 8 hours in normal circumstances. Also about your question concerning accounts, while I'm not seh6183, personally I only have my email account synchronizing and the very same thing happens.
Something is causing the CPU to remain awake, in my case stuck at 800MHz.
The factory reset will most likely solve it, but it'd be best to find the culprit to just try and rectify a specific anomaly rather than reinstalling the whole system.
Has recently any core Google apps been updated? Email, Maps, anything?

I do agree that in 8 hours of non physical use your battery should not be going dead. So I couldn't sleep last night and I did some google searching. Here are some things I found out.
Do you have Googles Goggles installed? Seems it may have a bug where it keeps the camera on even when the phone is supposedly asleep.
Seeing that seh6183 always has his wifi active maybe it has something to do with wifi. I found this from Juri's TechBlog
couple of days ago I finally got the eagerly awaited system upgrade to Gingerbread on my Nexus One. The update went pretty well, although some Nexus One users reported about problems with the updating process. The only thing I noticed is that Dropbox didn't work after the upgrade.
A re-install solved the issue. All-in-all Gingerbread is great. Beside UI enhancements it feels also faster than Froyo. However, after trying it for two days now, I noticed a substantial increase in battery consumption. By looking at the system battery stats (Settings -> About phone -> Battery use), Android System was listed to consume 23% of the battery .
Apparently the problem is a bug in Gingerbread version 2.3.3 (you know there is 2.4 as well) on how the system handles the Wifi adapter. If you go into your Settings -> Wireless & Networks -> Wi-Fi settings, press the menu button and click on "Advanced", you'll see a menu entry "Wi-Fi sleep policy". Gingerbread seems to have a problem when that option is set to "When screen turns off". While that may sound to be the most energy-saving option, the bug turns it into a battery killer. If you switch the option to "Never", the Android system will only consume ~3% in the battery stats.
Obviously, in addition to this, the best battery saver is to just turn Wi-Fi off when you don't need it . Caution, if one of the future updates fixes this problem (which I strongly hope), you have to set the option back again.

Something I didn't see but killed my battery on my windows mobile phone was instant messengers. Do you use any apps that are for instant messaging.
Found this thread also talking about the same bug with wifi
http://code.google.com/p/android/issues/detail?id=15057
So it seems that if you (cmdr001) also are a full time wifi user, you may be affected by the same bug. Check your wifi sleep policy and adjust your settings to "Never".
Install a battery monitor app from the market or spare parts to see what is using your battery. Install Juice Defender to stop all that excessive useage.

Excellent find!!!!!
Just switched the sleep policy to "never" (which ironically I've always used until very recently). Ill return with results after about 5 hours. The only thing is that I'm on android 2.3.5 not 3.3 so we will have to see if the bug was affecting me.
I also don't have Google goggles. And to the above poster, my phone regularly went into deep sleep so it wasn't my CPU that was staying active.
Oh and I've been using watch dog to look for rogue programs for the last 24 hours. I haven't got a single alert.
Sent from my Microwave

I guess the first question should have been what ROM were you using and to try a different one then. Needless to say it still has 2.3.3 components in it. And if you recently changed that setting then my bet is thats the issue. Goodluck.
Watchdog may alert you if you are using too much cpu at one time but I don't think it will let you know what is constantly using the cpu.

Ok there's a glitch somewhere in the battery tracking. I just checked it and android system was consuming 12% battery. I placed one 17 minute phone call and re checked it, I then had 57% android system consumption.
No way.
I'm using a cm7 nightly and I'm about to flash the stable version with a different kernel. Ill do a full wipe as well.

You could check your wakelocks.

After recharging my battery to 100% and wiping the battery stats, my android system consistently uses 2% of the battery, while the display sucks up around ~40%.

I startes noticing that even after quite a few charge cycles, I'm still getting 4-5 hours of SoT over less than 24 hours. The phone is awake 24/7, and Android System seems to be the cause, but no idea why. Does anybody have any suggestions? I've attached some screenshots.

Factory reset?
Sent from my Z3

Maybe you have some apps causing wakelocks, showing through Android system? My dad had massive data usage from Youtube which confused me until I uninstalled an app that used YouTube.

Yes something that you have installed is causing the Android System to run for extended periods.
I would first try, disabling some apps in the settings menu, to see if that helps. (like throw, bluetooth, NFC, wifi, hotspot) see if any of those help
I would factory reset, and be very careful about what you install back onto the phone initially.

Or instead of reset try, clearing out all apps and re-install one by one untill you hit a bad one. If that does not work I guess reset.

In Settings>Power Management, there is a selection called "App power consumption". Have you checked there? There could be an app listed that drains the battery.

I had checked app power consumption, and unfortunately it didn't give me any further information. Better Battery Stats is also almost completely useless without root, but I did try it and saw Performance Manager or something to that effect was what was keeping it awake (in Kernel Wakelocks). I ended up doing a factory reset, and it seems like it's working fine now with the same combination of apps.
I think I disabled something I shouldn't have using pm block (package), since after some searching it seems like the phone might have been constantly searching for a blocked package, keeping it awake. It's working fine now, thanks everyone for your suggestions!

Why do Android System, Android OS, & Bluetooth account for majority of battery drain?

Why do Android System, Android OS, & Bluetooth account for majority of battery drain?
On my old Galaxy S4, I found that the screen was almost always the highest battery drain -- and if I saw some app using close to or more than the screen, then I knew something was wrong. However, with my Galaxy S5 (running OptimalROM 13.1), I am consistently seeing Android System is the highest drain, followed by Android OS -- at times I'm getting only 10 to 12 hours of life, but other times I get over a day -- in both cases, it's the Android System and Android OS using the bulk of the power, never an app.
I also see some odd things like Bluetooth using nearly 10%, even though it isn't connected to any devices the entire day -- why would it use that much on standby?
I also see Google Services sometimes using over 10% -- I think that was while I had Google Maps in the background (not navigating).

I believe that is the new normal. Unfortunately, "Andoid System" in our battery stats is nonspecific: that heading actually covers dozens of little apps and functions. With each successive generation, the phones try to have more features.
You can get a little better idea with GSam Battery Monitor: by clicking on the "Android System", it brings up another window showing you all of these processes. That doesn't mean you'll be able to do much about it, though.
I was able to solve one major problem with ridiculous battery drain by looking more closely: I have a lot of mp3s and pictures on my sdcard. Android system was scanning them, but Samsung indexing service was also scanning them for no useful purpose, and every time I rebooted it would start chewing on them again. I froze the samsung indexing service and the battery life improved by many hours per day.

Where do I disable the Samsung Indexing Service? I doubt it's causing problems, but it's useless to me.

The safest way is to use Titanium Backup to "freeze" IndexService and, optionally, "S Finder". If you run into any issues, you can re-enable them easily by "defrosting" them.
Disabling them doesn't affect me at all because I use a file explorer to browse to my files directly.

OK, I installed GSam Battery Monitor a few weeks ago. Today I am dumbfounded by what my phone is doing -- after undocking it for just two hours and not using it at all, I notice it is hot in my pocket, so I pull it out and see the battery has already dropped to 78%. I check the list of open apps, and there's not much there -- my phone dialer, Camera, Chrome (with no pages open), and Messaging -- that's it.
I check the GSam battery usage, and it says the screen is using 2%, the cell radio 2%, the WiFi 1%, and the rest is "App Usage" -- I click on apps, and Kernel (Android OS) is using ~60%, Bluetooth is using 22%, and Android System is using ~10% -- so they combine for 90% of "App Usage". My Bluetooth is "on" but not connected to anything -- indeed, it is paired with only one device, which I have not even turned on in months -- the phone is getting all of its data via WiFi, which is only using 1%, yet the Bluetooth with nothing to do is using 22%!
What the hell is going on?

I know that sometimes it gets hung up if it encounters a corrupted media file while scanning for them, and that produces the symptoms you're describing. Scan your SDcard (it's fastest to do it on a computer, but there are many ways to accomplish this) for any files that are of size "0 kb" (that is, zero kb) and delete them. See if that resolves your issue.
Also try clearing cache and dalvik cache, just because that can alleviate strange problems for no discernable reason.

Need help on battery life and CPU usage

I have a Samsung Galaxy S7 and the battery was doing fine. A few weeks ago the phone started getting quite slow and the battery life went way down. I had installed a few apps around then, so I removed them and still battery life was bad. I tried restarting the phone and that didn't help. At the time I was running Marshmellow and I was using OSMonitor to watch the system. I was finding that Android OS was taking most of my battery and 30% of the CPU all of the time. Not long after that Nougat became available and I upgraded thinking that might help. It didn't help and OSMonitor no longer worked. I switched to GSam Battery Monitor and used adb to give it the permissions to see all app information. I'm still finding that the Kernel is taking 28% of my battery and Android System is taking 37% of my battery and I can't figure out why. I would rather not need to do a full reset and install all of my apps and settings again, so I'm asking if anyone out there has ideas on things to try and fix this. This is a non-rooted phone running the stock image from Samsung/Verizon.
Thanks for any help.

try activate the Battery Saving option and use it for a day and see if helps

I've had this happen to me before. The phone was getting seriously hot while it was happening too. I decided to do all I can without doing a factory reset (I was on vacation at the time, so no access to something to backup my data).
I cleared the cache of all apps. Then I disabled all of the stock apps I didn't need (like Gear VR). I also shuttered apps running in the background to about a max of 3 apps open at any given time. That stopped the insane heat issue, but Android System was still sucking 30% of the battery. I turned off Always On Display, that got me down to about 25%. A factory reset got the phone down to around 10%, and I never saw the issue again.
Before you do that I would recommend checking out this thread below as there does appear to be a bunch of other possible solutions provided by others.

Try this , it helped me a lot .
Download from the XDA forums the Kernel named : "Apollo Kernel" v7
Just flash it , and when you install it , if you dont use your phone for high end games or hard work,that requires high end specs , then you can underclock the cpu/gpu .
It s a battery life saver, plus , your components will be much better in terms of thermals/life

Battery life considerably worse after update to 9.0

OTA update to 9.0 available a couple of days ago so I let it install. Since then, I've seen considerably quicker draining of the battery, with my usage of the phone being much the same as before. For example, when I went to sleep last night the battery was at 64%, and there were no apps running according to a swipe up from Home, but when I woke this morning, battery was down to 2%. I normally charge once a day, and previously the battery was hardly ever below 50% after 24 hours - I'm a pretty light user.
As an aside, with 9.0 there no longer appears to be possible under battery usage information in Settings to see the percentage of battery that has been used by the various apps and processes.

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...

Battery on my P2 has significantly improved with Pie even if I didn't have any major problem with 8.1 either. Overnight drain 3-4%. After regular use after a full day I easily exceed 5h SOT. Everything stock with just Greenify in non root mode. I couldn't be happier, best Android release so far for me.

I've had my p2 installed with PIE for about 2 days now. I suggest giving it a week (which is what I'm doing) and then getting a full overview of how my battery is performing. Usually, after any major OS updates, being that apps are trying to utilize your resources and a new version of Android would try to allocate and learn your usage (in this case battery), you'd get a much better definitive idea of your overall performance.
I also think that since its now available, turn on Adaptive Battery mode. After a day of upgrading the OS, Adaptive battery at my 26 hr mark of upgrade said that one of my apps was taking in a lot of resources to be used in the background (ES File Explorer). I made AB to stop ES from taking battery resources.
So in conclusion, if it a week and then you'll be able to get a better overall understanding of whether your battery REALLY has gotten worse or better.
Hope this helps!

Interestingly, my battery was dropping really quickly too after the update to DP3, I switched off Adaptive Battery and it fixed the issue completely.
I tried it again with Android Pie and the issue resumed, so I turned it back off. Maybe try this too?

Exact same problem here after updating. Even tried a factory reset in case it was an updating issue. Same problem. My battery is currently at 43% 4 hours after a full charge. And I've barely used it. This is really poor.
No new apps installed.
My Oreo battery life was great. I'll try shutting off adaptive battery as suggested - but seems a real shame if one of the flagship battery saving features is doing the total opposite on Google's current flagship phone!
Doesn't seem to be a massively common issue so not sure if a likelihood of a patch either

Just a quick update - Google play services has now become the biggest drain on my battery, just as it was before I factory reset after the first install...
Anyone else had the same?

I had the same issue and did the same thing... until dp3 and my battery usage was terrible again even with adaptive battery turned off. I ended up turning it on again and after about a week my battery usage was back where it was before. So there doesn't seem to be a magic bullet here. FWIW app usage offered no insight as to what was causing the drain in the first place.

THIS.
I got like 8+ hours of SOT.... no mobile network though, all day wifi use only.

I have this issue. Dropped about 40% over night. I found that turning wifi off stopped the drain completely. I did not have this problem with Oreo at all so it's not the networks im connecting to. Weird thing is this did not happen when I first installed Pie. This started happening about 3 days into installing. Also, I put it in safe mode and saw the same drain with wifi on vs off.

Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
I've gone from draining 8-10% an hour (screen off) to around 2.5%/hour and from 1hr 35 total SOT to 3hrs 39 minutes with 32% left (and an hour of that was Google maps navigating, so a proper work out for the phone).
Do give it a try and let me know if it works for you.
Although there's room for improvement (idle 2.5%/h seems high to me!) and it's ludicrous that I should have spent several hours finding a fix for this on 100% stock android, I'm very happy to have a usable battery life back again...
Adam.
UPDATE: Seems like in the night I lost 40% again. Idle drain climbed it's way up to 5.6% in the night. Still an improvement from where it was before, but not quite as good as it first appeared...

@Burkules I drop 0.4 - 0.7%/hr over night with Bluetooth off/Wifi on/strong cellular signal. Much the same as it was with Oreo. Not quite sure why's there's such a big range (almost 2x) but either way it's ok for me. Did you try the technique above?

Cheers for getting back on this.
I left it on safe mode the other night and it still drained absurdly fast, which suggests to me it's a google system drain rather than rogue app, but will try again with app preview now switched off. Likewise will try greenify again and report back.

Likewise maybe app preview set to off will help me even more. If I recall correctly rogue apps can cause some google system apps to wake up, but perhaps not in safe mode...

So, switched off adaptive battery again (i'd enabled it after my short-lived miracle recovery the other day) and now I'm down to 4%/hour. Which is better but still really high for idling! Cleared cache and data in Google play services for good measure too as it still comes up super high on the list of battery drainers.
Booting into safe mode now to check the drain without adaptive there and will report back...
UPDATE: Exactly the same drain in safe mode. This is a straight up google problem....

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.
Have you seen any improvement in yours with any of these workarounds?

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.

Nothing to lose by trying. And as I said, Greenify makes it easy/quick to do. Force closing is almost as good as uninstalling those apps as the vast majority of installed apps won't restart or run in background until you use them for the first time again. In my experience, quiescent battery consumption (e.g. noticed over night):
Is vastly affected negatively by poor cellular signal strength. Marginal coverage can really drain the battery fast.
Gradually gets worse between reboots
Can be improved (once it degrades) if you force close all the apps you've installed, and swipe away the background apps just before you go to bed!
If quiescent consumption suddenly rises I can normally fix it by force closing all the apps (not being sure which was the one gone rogue/suddenly misbehaving)
At night I generally have excellent cellular coverage, good WiFi, and Bluetooth is off. NFC is always off
I don't enable sync on 2 of the 3 Gmail accounts I have configured
I disable notifications from any apps I don't actually need them from
Quiescent battery consumption is between, say, 0.4% and, 0.7%/hr at home, around 2 to 3%/hr when out and about which I put down to all background data being driven over 4G instead of Wifi, and variable cellular coverage
I've not noticed quiescent battery consumption change between Oreo and Pie, but this may be because I keep force closing apps at night and not giving adaptive battery (which I have on) a chance to have the same effect intelligently
Turning off app preview messages has made no practical different for me
I'm completely stock (stock launcher, not rooted, etc.)
If you can't fix it, at least a factory reset as the next experiment has the option to restore *most* of what was there before (so long as you have had the backup setting enabled). But because not everything is restored it's still a pain. And if that doesn't work it's another factory reset and test and then restore everything manually and gradually :-S. But I think you already tried that?

Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
Thanks, just tried that as well and my battery has stayed resolutely at 68% on idle beside me for the last few hours, previously it had gone from 100% down to 69% in about 4 hours whilst similarly doing nothing.
