[Q] "Android OS" and battery usage

Hello.
Sometimes my phone works normally about 25hours, sometimes it works twice shorter ~10 hours. I've analyzed battery usage and found out that only difference in Android OS process.
25 hours battery usage
Display - 60%
...
Android OS - 4%
10 hours battery usage
Android OS - 60%
Display - 15%
This definitely looks like a bug. OS should not use more than a display.
Is there any way to found out what is Android OS in details?
Why it takes to many power?
P.S. I guess that bug is triggered by programs like Google maps,
but can't definitely confirm it.

Is there a way to shut off maps till needed?

Get spare parts and you can check what is using what. It could also be useful to get watchdog or similar app to check if you have any apps gone crazy. It isn't unusual though that the screen usage is lower if you just haven't actually used the phone that much as the percentage is always 100% and is divided among the things that used the battery, thus the usage percent doesn't imply mA usage.

I have still pretty high "Android OS".
Display 31%
Android OS 21%
I've tryed Spare parts (Battery history), but it doesn't help.
It just doesn't display such name.
Is there any other way to find out whois is lurking
behind this mysterious title?

I'm betting you have a "suspend process" issue.
What does Battery history from spare parts say? Choose CPU usage, Since last unplugged. Is "suspend" close to the top? What CPU usage details does it have (if you select it)? Obviously look at this data at the end of your phone's battery life, before you plug in.

Also what rom are you using? With cm7 it seems that the battery stats are quite crazy and don't seem to add up to the actual usage, it's been discussed a bit in the nightly thread. The inaccurate stats don't explain the changes in actual battery drain though...

just to be sure, you have usb debugging enabled right?

I'm on official ROM (no root) with USB debugging enabled (I confirm init issue).
My last guess that "Android os" caused by "Location -> Wireless networks".
Now have ~2 days uptime without ever running "Google Maps" and with "Location -> Wireless networks" constantly unchecked.
P.S. Spare parts constantly eats about ~3% CPU at top. Too many for battery monitor. Removed it.

Hey, since you're worried about slight additional CPU-usage and overall performance, you really should consider S-OFFing and getting a different Radio and a custom ROM like ARHD. Or at the very least flash a new kernel, Buzz' kernel did wonders for me.

Android System High Usage

Hi guys,
Anyone have an idea what would cause my battery stats to have very high "Android System" usage all of a sudden. No new apps installed.
Thanks

I'm seeing this get pretty high as well. Starting to wonder... TW really limits the information in the Battery Status dialog. Hopefully we'll get ROMs soon that have more detailed information like I had in MikG.

It has always been a bit higher than I am used to. I just grabbed the new version of betterbatterystats from here: http://forum.xda-developers.com/showthread.php?t=1179809
Hopefully I can use this to figure it out.

Please keep me posted if you find anything

System Panel works really well for me I found. Paid version is totally worth it, too.

Just another thought/question...
I am assuming since it is "Android System" causing such high usage ( I have 5% battery left and android system is 30%), that it cant be an app I installed causing the issue.
It has to be something that is either part of the stock ROM (I am stock, not rooted) or something core to the android operating system. PLease let me know if you agree with my logic that it cant be an installed app.
Just trying to find the root cause at this point or determine if I have to hard reset which I dont feel like doing.
Thanks again

The original SGS2 has an issue similar to this.
http://forum.xda-developers.com/showthread.php?t=1290020
They discovered with it that the processor has to ramp back up to 800MHz to do its pre-deep sleep tasks, in addition to taking longer than normal to do those tasks. So with a phone that woke up often to sync, even limiting the processor to 200 MHz with the screen off, it still spends a considerable amount of time at 800 MHz. I don't think they have a fix, but you can work around by limiting the amount of syncing the phone does while sleeping.
Don't know if this is related, since TMO SGS2 doesn't use the Exynos.

Thanks for the reply. My problem is that the battery usage for android system used to be 5% or less and now out of the blue is 25-30%.

Did you change any sync settings? Setting up an email account or maybe a widget to sync could do it. The phone has to do a bunch of system related tasks when it wakes up and goes to sleep, and those fall under "Android OS", so even if it is waking up to sync for an app, the system still has to do stuff, and more than usual when coming out of sleep. Like the other thread said, the original SGSII does all these things at a far higher clock speed than it needs to, and takes longer than most phones do.
I myself don't have the phone yet, nor do I have an original SGS2, but you could look up much of the same information the gentleman who wrote up the OP in that thread I linked to see if the issue is related.

I was so annoyed with this issue that I decided to do a factory reset. I dont think it helped.
So far after being off the charger for 2 hours....I sent 5 texts, browsed web for about 5 minutes. I am down to 87%. Display time is 46%, used for 18 min and android system is 17% with stay awake time at 3 minutes, and there are other items taking up battery at 5% or less like cell standby, android os, market
Does this seem normal, I never rememver android system taking up over 5% even with little usage. I am actually pissed because I would have thought that a factory reset would have helped for sure.
BTW, I am only syncing one acct, Google

I've been watching with betterbatterystats for a couple days now. I've got Skype running in the background so I expect that to use some battery and cause some wake ups.
But it has turned out that location services and updates have been doing a lot more, as much as 7000 in one day. They show up as something related to Maps, but I think that it might be Latitude. So I have disabled that location tracking. We'll see if it helps, there isn't much more using my battery. It is just something keeping it from deep sleeping.
If this doesn't work I'll look at other location apps like weather and such. I already uninstalled Accuweather after reading about how they transfer your location tracking information over the Internet unencrypted!

Android OS killing battery

Hey everyone
Got a Nexus a couple weeks ago after having iphones for a couple years. Loving it so far.....ICS is very polished.
Initially, my battery life was adequate. However, recently the OS is using 45% battery and the phone gets a very hot when idle (I can feel the heat in my pocket)
I did a factory reset and still the same problems.
Is anyone else coming across these issues?

An old bug cropping up again?
http://forum.xda-developers.com/showpost.php?p=13247149&postcount=57
Can you please install Watchdog (https://market.android.com/details?id=com.zomut.watchdoglite) and let us know if it's the suspend process (which shows up in the battery meter as part of "Android OS") burning through the battery?

My phone has been on standby for about a day and has 80% battery left. However the battery consumption shows:
42% Android OS
37% Phone Idle
16% Cell Standby
- Also what is the difference between phone idle and cell standby
MY BACKGROUND APPS RUNNING ARE:
- Battery Monitor Widget (I need this on so I can tell what my battery life is easily)
- Google Services (What is this, can I kill it?)
Media (What is this app, can I kill it?)
Music (Again what is this, what happens if I kill it/should I? I never used it.)

I have the same problem. My SGN died after 7 hours without any usage.
Sent from my Optimus 2X using XDA App

Yup, me too. This morning, I took my phone off the charger at 98% for an hour and 15 minutes and didn't touch it. The battery had gone down to 88%, with Android OS using 64% and Android System using 14%. The phone was 'awake' for the entire period. I've had my Nexus since Wednesday and I haven't been getting great battery life. I'm hoping there's a fix for this.

Same problem here... (I testing radio UGKK7, XXKK7 and XXKK1... all with the same problem).
- Lightflow increment "Android OS" battery use.
- By using, Wi-Fi "Android OS" uses less battery.

try disable wifi when not on and unchecked "use wifi network" for location.
another thing could be some active widgets, i remember this was a problem a while back.

Note sure that this has got to do with wifi at all as I reset my phone to factory and I still have the 'Android OS' usage taking 23% of battery. I have no apps nor have I yet linked phone to my Google account.
I have read some comments to do with the Galaxy S2 which too suffered from the same problem. I remember reading something about Samsung driver implementation causing this with the S2. I will update the links when I find something conclusive. Also I have another HTC desire that has the AOSP code compiled rom and that does not suffer from this at all and it is happily sitting idle at almost 2 days with nearly 70% battery still left.

Yes, the problem was with the suspend process eating up CPU. You can install Watchdog and set it to watch non-Android processes, and that will be able to tell you which "Android OS" process is actually the one eating up battery.

Is samsung aware of this problem? We need to file complaints.

Do you have your email or anything set up to receive things instantly? That can have a noticeable impact on your battery if so

Thanks Chirality, but I assume that this is happening to all users? Samsung have seen this before so shouldn't this be fixed from the very start? Wrong person to ask this question to, but it is annoying..
Anyways I will install Watchdog like you say, but unless I can kill the 'suspend' process, I am helpless.

Is there anything in the logcats that could hint to a problem? Like errors or something unusual that it keeps repeating

I have the same problem with high system CPU usage. I used SystemPanel to monitor the phone (unplugged, standby mode) during my 8-hour sleep and here's the results.
The System Processes were using 49min of CPU time while the phone was idle
When I clicked on the system processes I got a list of individual processes. Anyone knows what are there kworker processes for?
When I clicked on one of the System Processes (kworker/u:1), I got its CPU usage. It was doing something almost the whole time
Finally, I should also mention that the phone lost about 7% in these 8-hour test. Seems ok but I think it would be even better when this high system CPU usage is fixed.

Hmm...Now that you asked this, I remember watching logcat output and was getting a null Notification event almost one every minute a couple of days back. I therefore proceeded to uninstall all my widgets/apps but I could not reach to a conclusive outcome.
Anyways as Chirality pointed out this post (Link) indicates a 'suspend' process issue. And this guy identified the process causing it (Link), I think!

A driver issue definitely sounds plausible but there are also a lot of things different between these two phones, especially between GB and ICS.
Watching /proc/kmsg should show something if it is an issue with the kernel

Chrality, xHausx
I have installed Watchdog and set the settings to what you indicated. I am a bit confused around the app, so I have added screenshots to update you of the data at my end.
Do let me whether you see the issue immediately or need any further information.

My experience is somewhat the same.
Out of the box battery life seemed pretty good. After the update to fix the volume issue I started to notice that the battery would fall even when the phone was idle. Android OS was the culprit. I am now running MCR and I have the same issue.
It's not terrible battery life, but it's substantially worse than it was out of the box.
I did wonder if the problem was related to how they fixed the volume bug. Is something always running to pick up the volume bug problem and deal with it when it happens?
Just a thought.

Interesting. I've been thinking the same thing, and the annoying thing about that is the problem doesn't affect my network (T-Mobile), so I could be getting reduced battery performance for no reason! Ah well.

S3 Massive battery and "Android System" usage with and without charging

I'm having a problem with my Samsung Galaxy S3 (rooted, but no custom ROM) through AT&T where it's losing battery power at a much higher rate than normal every once in a while.
Specifically, today, I was using the GPS feature and charging it in my car, and yet, even though it said it was charging, the battery continued to lose charge. Also, in the past, the phone has lost charge very quickly, and when I check the battery usage, "Android System" is very high on the list, up to 60% (with "Screen" being at 11%, which is usually the biggest culprit for me since I leave the screen on a lot). One time, I went to bed at around midnight and had forgotten to plug in my phone. When I woke up it was off. I turned it back on and looked at the battery stats using 3c's Battery Monitor Widget and saw that it lost charge quite slowly until about 5am, when suddenly the usage went up dramatically, and the phone went from about 60% to 0% in the course of an hour and a half of non-use.
Because this is not a problem I can reproduce on command, I'm not sure exactly what application/process is causing it. Does anyone have any suggestions or has anyone else experienced things like this happening before? (Besides me having to pay for the "betterbatterystats" app?)
Edit: Also, "Android System" sometimes is sometimes listed as "gsiff_daemon" in the battery stats, and within 3c's Battery Monitor Widget, Android System is separate from "gsiff_daemon", where gsiff_daemon's usage is almost 15 times the usage of Android System.

Checkout this thread to see if the gsiff_daemon is your problem. tl;dr when the system is hot and tearing through the battery, go to system settings -> Developer options -> and check Show CPU usage. If gsiff_daemon is the top or second highest on the list, then that is your problem. To solve it for the moment, use system tuner, or something else, to kill gsiff_daemon. There is no permanent cure at the moment, other than to delete gsiff_daemon. Both of those fixes require root, the non-root fix is to reboot.
If gsiff_daemon is not on the list, then something else is the problem, but Show CPU Usage should give you an idea of what system process is running hard.

Samsung Push problem
J M L,
Thanks for the information. I'll do that if the problem arises again. However I also did something else that looks like it may have been the solution for my particular problem, which was disabling the "Samsung Push" service in the Application Manager. So far, my battery life has gone back down to very reasonable levels.

Interesting, I installed "micro cpu monitor" shows thin line at top of screen showing both cores.
I haven't had this happen for some time now but after playing with google play and maps downloading offline maps etc I noticed my 2nd core pegged out.
Having seen this in the past & ignoring it I now realize that majorly drains the battery as well as it getting warm.
A simple reboot seems to be the only thing that fixes it. Clearing ram and closing recent screens dies nothing to clear the "cpu jam".
If left alone, it always shows the culprit as "android system"
As to what part of "android system" I don't know.
But until we figure this out for good, that little micro cpu monitor. App is sweet for peace of mind to know all is well or whether a reboot is needed. For what it's worth, I also noticed that after the event, that my auto rotate to landscape was mysteriously unchecked?
If it jams again, I'll have to see if it gets unchecked again, unknown if there is a relation.

also do any of you have motion settings enabled and/or autorotation on?
Seems it has to do with the gyro issue
also are you guys rooted or non-rooted?

i noticed this today and while troubleshooting, noticed contact sync from google says "sync is currently experiencing problems..." maybe?

I read the thread about gsiff_daemon culprit. I had it listed as a possible battery drain culprit. The thread says the issue may happen after a hot reboot...which I did have. Killing gsiff_daemon was not immediately effective. I renamed the file so it wouldn't get used...like the thread recommended. I had to reboot to get normal battery drain back and have yet to see the issue again. But i wont know for some time...or maybe when/if i get a hot reboot...which is really rare. Do yourself a favor, and buy better battery stats. Its a must have tool...and it's not expensive.

I wonder if this problem has been solved with latest lj7 jellybean from sprint

so with some trial and error i found some resolutions ..
first, i used Watchdog and it told me that the media services is killing battery too.
so doing a full wipe does not always fix this.. but what does, is reboot and wait about 1 hour charging and it will calm down. this was just something i noticed. so what i did is wipe out my SD cards, both of them, cleared them out 100% formatted the External SD, and used recovery to format the internal. From there it seem to work, i put my stuff back, and it seems ok.
problem is, when you install a lot of rom's and have bad reboots some files get messed up and you have to do it all over again..
problem was with AOPK, CM and TW roms.

My experience with froyo/gb/ics is that things have been getting progressively better over the years. But with each so called UPGRADE of an OS or even APPS, we often have to deal with bugs or incompatibilities. I am eager to upgrade to a stock based JB soon, but wisdom says, for 20 things improved, there will be 5 things broken....or hurting in some way. Early adopters suffer the most as usually these issues get ironed out...most of them.
BUT...these stuck drains...wake locks etc., it seems they will happen when they do no matter how many issues get fixed. Over the years, I've had random standby drains caused by Maps/Nav. Maybe it's ok for months, then after a particular update, it's back...and unpredictable. The YES...a reboot, just like with a PC, is a quick short term workaround.
Finally, with the App CURRENT WIDGET, there is a provision to watch for high drain in standby. It watches MilliAmp (ma) readings over time..to determine if you have a rogue drain. That's different than monitoring the CPU. (Some drains do not cause much CPU activity) BUT UNFORTUNATELY, that app won't work with our S3's because of a lack of hardware support. Works great with HTC and many others. It's a bummer because I used to use it and have my HD2 reboot if a 15min consecutive high drain was recorded in standby....thereby saving the battery and usually killing the bug.

Crapppp
Jellybean didn’t solve it. Gsiff_daemon just popped up for me. Just renamed it AGAIN.
Hopefully it won't pop up again

Question about battery

Hi there,
Recently I got a secondhand HTC wildfire buzz and the original battery had a remarkable short life. After + / - 6 hours was empty.... without touching the phone!.
I replaced the battery by a new one with slightly higher capacity (1500mah) but after approx. 7 hours this one is empty too!....without using the phone, I mean the phone was closed with the on off button, not used and checked after 7 hours
I can not imagine that this is normal and I'm wondering what can be the cause of this problem?
Specs:
Android 2.2.1
kernel 2.6.32.21
Build number 2.22.405.8
- Phone was connected to my local wifi
- Only app in background was What's app (didn't send or recieved messages)
- Killed rest of apps with "App Killer"
- Noticed a few processes with the app "OS monitor" and the process "Android-system" used between 8-20% CPU. And the process "System" about 2% CPU
I can not imagine that this is normal and I'm wondering what can be the cause of this problem?
Kind regards,

thats strange.

you dont gave proper description. well yiu are new so i consider you don't know about rooting process and your phone is not rooted.
first of all install wakelock app check from playstore. i will give you a hint wats eating your battery. well on froyo 2.2. plenty of battery monitors are avaliable. at last and the best follow some rooting guides in wildfire fourms. they are sometimes confusing for new users . well follow a method to install recovery and get rooted. install a new rom and recalibrate your battery. its a file that somtime help users .
at last if you dont want to root. simply erase everything and reinstall everything. but i suggest you to get rooted and soff. because froyo users now can not download anything from playstore. google has dropped support of froyo...

first of all install wakelock app check from playstore. i will give you a hint wats eating your battery. well on froyo 2.2. plenty of battery monitors are avaliable. at last and the best follow some rooting guides in wildfire fourms. they are sometimes confusing for new users . well follow a method to install recovery and get rooted. install a new rom and recalibrate your battery. its a file that somtime help users .
at last if you dont want to root. simply erase everything and reinstall everything. but i suggest you to get rooted and soff. because froyo users now can not download anything from playstore. google has dropped support of froyo...

I dont think that root is the answer here, also wiping battery stats from recovery does nothing except delete a batterystats file from the rom. no actual calibration happens. no need to rush off into s-off without a real need for it

Hi there,
Recently I got a secondhand HTC wildfire buzz and the original battery had a remarkable short life. After + / - 6 hours was empty.... without touching the phone!.
I replaced the battery by a new one with slightly higher capacity (1500mah) but after approx. 7 hours this one is empty too!....without using the phone, I mean the phone was closed with the on off button, not used and checked after 7 hours
I can not imagine that this is normal and I'm wondering what can be the cause of this problem?
Specs:
Android 2.2.1
kernel 2.6.32.21
Build number 2.22.405.8
- Phone was connected to my local wifi
- Only app in background was What's app (didn't send or recieved messages)
- Killed rest of apps with "App Killer"
- Noticed a few processes with the app "OS monitor" and the process "Android-system" used between 8-20% CPU. And the process "System" about 2% CPU
I can not imagine that this is normal and I'm wondering what can be the cause of this problem?
Kind regards,

To be honest with you friend it could be many things. ive seen many wildfires over the years that had massive battery drains just because they were old, with new batterys not really helping much. your device being on wifi is probably keeping it awake and not allowing for a deep sleep (which conserves more battery) if you go into wifi/advanced settings i think there is a option to have wifi always on during sleep. if that is ticked, then untick it and see if you gain any performance boosts. its also possible that your 3rd party battery may claim to be 1500 but it could be much lower. trusted brands are safer bets in these fields. also consider how you charge your battery, if you charge it excessively (much more that it needs, ie charged overnight while you sleep) then you could be causing permanent wear onto the battery.
as a last resort you could flash an android kernel that supports underclocking your cpu, that would increase your battery life but at the cost of performance. like the above user said try to install wakelock app and see if it pops up with anything useful but i don think it will

thanks
Thank you guys for the answers.
@sachoosaini
I did a successfull ROM flash on a HTC Prophet (QTEK S200) but that was a while ago.
@heavy_metal_man
I agree with you that it's hard to find the cause only with these info. Hard/software are very complex today. Yesterday I completely switched off Wifi but the results where the same.
I've noticed that the phone gets pretty warm while charging so perhaps that's the cause. I charging with a 5V 1.3 A usb charger.
Anyway, I'll try wakelock app to get some more info
Kind regards
