Standby current and identifying problem processes. - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Those of you using a battery app, what is your usual standby battery drain? I have been having some issues lately trying identify what's killing my battery on standby. I get pretty decent battery life using the device, but it seems to drain quickly on standby.
I am seeing 100ma+ with Wifi on, after turning all radios off and rebooting I can get it down to ~20ma or lower. It seems in the battery usage screen in settings that "Android OS" is using a lot of the battery, but it's hard to tell what actual service or process it is. Is there anyway to pinpoint the exact service or process munching the battery?
Thanks.

I'm no expert on this app, but Betterbatterystats might give you some useful information.

Thanks! That actually helped me narrow it down, it seems to be the "locationfriendservice" part of google maps, and a quick search indicated that this is a big problem for lots of folks.
It's possible I just had noticed it before when I was all stock, so I was thinking it was a result of a new kernel or something.
I have done what I can to mitigate the battery-hungry maps processes and will see tonight if I can retain better battery life (was losing like 10%+ in 6 hours on standby!).

[Q] 60 percent idle battery usage / 15 hours

I am having huge issues with my battery on my galaxy s2. It drains really fast, 60% over the last 15 hours this night when the phone has been idle. This has been an issue for about a week now; I cannot seem to find a solution? I have tried various roms, wiping and doing a clean install, but the problem continues. Currently using lightening rom 3,2.
Do anyone know what can be causing this battery drain? Is the battery defective??
What apps do you have installed?

That is quite a drain I can see there. The drain might be caused by having too many widgets or having too many applications open. If you plan to put it on standby, do close those apps that are not important to you.
Have you tried rebooting?
I have a stock lightening rom 3,2. no apps installed, except titanium backup pro and opera mobile. I have frozen all kinds of stuff in titanium to try find the cultprit, but without success. As you see, no apps except andoid OS is running. Same drain on villainrom, lightening. Don't know what can be causing the error. Is there some way to check if the phone or the battery it self is to blame?
Try with screen on - normally I think that should run for 6 hours or so. Using that as a reference, you can check to see if the energy stored in the battery is normal. It doesn't look like your OS is staying overly active to me.
Hi bjorninge,
Every time after you flash a new ROM you should calibrate your battery.
Get the app "battery calibration" from the market and follow instructions and please report back whether you can achieve better performance.

I have a similar issue, as was the same with my captivate. I have stock ROM on my GS2 though, the way I got it out of the box pretty much. Android OS takes up most of the battery usage. I don't know what it is. Widgets updating constantly? The constant syncing from Gmail/push email?
Well that's surprising! Awake and Screen On bar is quite low and totally synchronized, yet 60% drain, now I gotta say it's weird.

Tried calibrating the battery, but it doesn't seem to help too much

Unfortunately, I have the same issue as you've described above. I am running on stock KE2 kernel and the battery drain is quite a lot. The 'Android OS' is always consuming a lot of processor time on standby mode.
This needs to be fixed A.S.A.P.!
Download and install the app BetterBatteryStats from Android section, it is a very useful app which will show what Awaking the device from deep sleep and processes too. For me, it was the damn Latitude stuff going on background and wasn't letting the device to go to deep sleep.

Thanks for the tip. I have downloaded the app now. what spesifically should I look for?
You just look under 'Wakelocks' and you will know what apps are causing the Awake, then you could take further steps.
Regards.
Would be great if you could look at the screenshot and tell me if something is wrong. Also, after the battery calibration, I've "only" lost 26% the last 7 hours mostly idling. I don't see anything abnormal in the screenshot I provided :/
Well nothing is wrong imo as everything is very low. You should check those which are using more than 10 mins Wakelock, some seconds doesn't matter actually. And you can post any query further to the original thread of this app, here,
http://forum.xda-developers.com/showthread.php?t=1179809
Regards.
OK, So I'm now back to 12% battery usage (from 100% to 88%) with 17 hours and 30 mins on battery, which IMO is normal.
What did I do? Well, I removed the battery and put the rest of the phone into the stove for an hour on 50-60 degreed celsius. My 98% android OS usage is gone and the battery works as normal .I also had problems with the phone constantly going into "car mode" which is now gone.
I got some tips around the internet that my issues were all related to moisture on the inside of the phone.

10% battery drain overnight?!?!

I noticed my S3 drains about 10% battery overnight. I dont think this is normal. Wifi and 3g are off, it just lies there by my bed doing nothing. Ive restarted it and no help.
Cell standby shows 41% usage. Is that right?
The 2 red circles in the screenshot show when my phone is idle just lying there.
Any help?
We need more information. What apps run? have you remove/freeze bloatware. Are you rooted? what rom are you on?
I'm going to run this based on speculation perhaps side effects of rooting your phone? I know there is no conclusive evidence of this but a hypothesis as such. My apologies if you aren't rooted.

why would rooting your phone create battery drain?
OP the standard answer is to install better battery stats and check it again to see what those wakelocks are. Once you find out why your phone is waking up you can do something about it.

I'm also getting a 10% battery drain over night. I've been putting the phone in airplane mode to see if that helps at all but it really doesn't. Anyway we can inprove this? 10% seems like a lot for sleeping...

install better battery stats and find what causes wakelocks......as above post!
Sent from my GT-I9300 using xda premium
thanks for the replies everyone, Im using the latest stock firmware... no rooting here...
Installing better battery stats as we speak and see what they say...
GSam Battery Monitor and / or BetterBatteryStats would be the first place as mentioned already.
I was able to find what was causing me most issues. It was some Calender storage and Google syncs (bookmarks, contacts etc) even though I didn't have them activated.
Anyway, after freezing them I now only lose 2-3% overnight. That is with gmail push, email sync every 4 hours and about 7 or 8 other Widgets updating every few hours. Mostly noticed a massive improvement when I flashed the latest siyah kernal.

I don't know but I get the feeling that rooting various phones might have hidden side effects as such, rooting your phone is still evolving as of today. There are still alot that the general doesn't know hence there are always new things about rooting although I might not be knowledgeable in that department. However is it possible to unroot your phone? rather revert it to stock? try doing that and see if there are any differences.

[Q] Battery Help in a particular application !!!!!

I have been all over the web in search of something that will extend my battery life in one particular application. So far I am empty handed. I have contacted the application support staff and they say it is not their issue.
I use GolfLogix on the golf course. Up until a couple of weeks ago I had no issues. I could get thru the round and still have plenty of battery left to carry me into the evening.
Then one day without anything changing to my knowledge the phone began to run out of battery half way thru a round, somewhere around the 2-1/4 hr mark.
At that time I was running Ginger Bread on a Droid Razr.
They had me uninstall the app and reinstall the latest version. That did nothing.
Since then I have upgraded to ICS and that has helped a bit. The phone dies at about the 3-1/4 hr mark.
I might add that I am also running Juice Defender Ultimate.
I always start with an overnight charge and 100% battery.
It would appear that something in the app has changed even thou they say not or items in the background are sucking up power.
I have installed Better Battery Stats in hopes that would shed some light but I am not understanding what I am seeing there. Besides once the phone dies their is nothing there after recharging.
Can anyone offer any help or suggestions?
Thanks in advance
:crying::crying::crying:
Well from my experience Juice Defender causes more problems then good. Better Battery Stats will shed some light on what might be waking up your phone but what you might also want to check is to see if some application is sending/receiving large amounts of data, this will pretty much kill your battery because of how much of a battery drainer 4G really is. So just go to your settings and click Data Usage just to check if there is an application like that. I've been hearing about problems like that with the new gallery and such.

Thanks for your reply. I have done as you suggested and turned Juice Defender off. In addition I was able to fore the phone to 3G. That has always been sufficient for me in the past. If you have any other thoughts pls post them. I will come back to you after my next round of golf with the results.

[Q] Need expert help in analyzing my battery consumption

Hi Everyone,
I know there are thousands of threads regarding battery consumption on the SGII - I have tried many many suggestions and I still have terrible battery life. I was hoping someone could give me a hand in analyzing if my stats are normal or if there is anything I could do to make it last longer - my battery life is just terrible.
I'm running RootBox 3.2 Jelly Bean.
Please find attached my BBS and Battery graphic. Let me know if there is any other detail that I can attach in order to troubleshoot my battery consumption.
Thanks a lot in advance!
Try using 2G networks when you don't need big bandwith. 2G is enough for WhatsApp, WAP sites, messengers.

I have tried being on 2G the whole day with very similar results
Disable all data connections for a while and compare how much battery was used.
Try GetRIL to get a match baseband and see if it improve it.

Your log is not looking that bad considering your screen on time of about 2 hours and the CPU usage.
The cause of the largest wakelocks seem to be your music player and synchronization software. Maybe you could get less wakelocks by reconfiguring them.

So you are saying 2 hours of screen on time draining over 70% of my battery is decent? Not sure how much its supposed to give

No, this is not what I'm saying.
First the battery draining is not over 70%, it is 64% (according to what your BBS log says). Second, the amount of time the phone spends running with a 'high' CPU frequency is quite large, or, in other words, the amount of time your phone runs at 'low' CPU frequencies or even better, is in deep sleep, is quite small.
Taking all this together I think you do not have abnormal or excessive battery draining.

Battery drain

I've come from using the ipad air to the Z2 and over night the battery drains by over 50%.
See attached.
I didn't use the device at all and stamina mode was on. This is frustrating since the ipad can stay in standby for days without even 5% drain.[emoji15]
Anyone?

Well, for starters, not sure if the battery temperature chart you attached will help.
So you say it goes from 100% charge to 50% overnight? If so,you got some serious issues there. Typical loss is from 3-5%.
But 50 is absurd.
When you check the battery usage, what kind of usage is going on? Display of course is a biggie and uses the most. It's possible some application is keeping the tablet awake/display on. This might explain it a little.
I will explain how to read it. If the usage chart states "Display 54%", then it means of the 50% battery you lost, the display was responsible for 54% of "that" figure. That's how to properly read it.
But you need to find out where the drain is. I suspect a "rogue" app or a bad battery perhaps. A rogue app can certainly cause it, as with running some strange mods that just don't get along well. So you are going to have to hink back and remember what you changed just before you noticed the drain.
You can install an app called Better Battery Stats, and it might actually pinpoint what is causing the severe drain.
You have already installed GSAM Battery Monitor, so you should be able to find the cause for your battery drain.
Do you already have the Root Companion App installed, too? If not you probably should do so, this should provide better stats. Your tablet needs to be rooted, though.
After the drain appeared, open the GSAM-App and select ´App Usageˋ or so (my app is in German, so I donˋt know exactly). Then select ´Show Kernel Wakelocksˋ or so.
Now you should see how long your device was awake and what caused this.
Hi guys! Thanks for your help here.
I have found out now that the battery is definitely faulty as it went dead last night and I tried charging for 2 hours and it still won't turn on.
I am sending it back for a replacement.
Again thanks for your help

No problem. At least you know the cause. Personally I can't recall a bad battery on a new tablet, but I would think it's possible as many tabs as are sold. Sucks you got one though.
