Hello folks.
I'm currently on Aokp 4.2.2 unofficial with Francos r90 Kernel, bootloader and Radio are both updated. I'm suffering from massive battery draining. I guess something isnt letting my CPU sleep properly, as i always get messages like "100% awake while screen off" from battery stats plus. I'm just getting up to 2 hours screen on time, and battery is falling by about ~7% / hour With normal usage (whatsapp, News, xda) and like 15 Minuten screen on time in that hour. Also, see the attached Images. I sometimes have wakelocks by audioOut_2 and as you can See, maps is using more battery than the Display itself.
On an additional Note, GPS is always off, im using Taster to locate, but with cell near only.
Would be very Kind to help me out of this issues, thank you a bunch!

Turn off Location Services for a little bit to see if that helps.
You should try a program like autostarts, and don't allow things to run unless explicitly started by yourself. This way it'll help identify if there is an misbehaving program.
I saw you were using franco r90 which could be an issue. Try going back to the last stable
I think you will like this application.

This simple application will make your annoying applications to go to sleep. Therefore your phone can finally go to sleep like it should when it's not in use. I see that Google maps seems to be the culprit in your battery drain. You can use titanium backup and delete it and install it back again from the play store. After that you can use the application that I've given you and force it to go tot sleep.
Here's the forum for the application:

Thanks for your reply. Yeah im already thinking about flashing matr1x or trinity Kernels. How much screen on time Do you get with matr1x?
I reinstalled maps, greenified maps and facebook. Updated to Franco 92. Already getting better results with greenified maps, but i get following wakelocks:
"pm8921_eoc", "msm_otg" and AudioOut_2 and still notifications from bbs: 100% awake.
Apps running are: astrid, avast, Francos updater, Rom toolbox, Tasker

Does anyone have some knowledge about How to identify why Android OS is consuming so much battery Life? While screen off some process is waking up the Device, up to 1.5 GHz.

Coming from the iphone 4, good battery life is the most important thing i miss. I need a rock solid reliable phone or else would have started to mess around a read about Kernels to see how they may help with better battery life. My iPhone would last me 3-4 days of general use. To me General use is very light use..! With nexus it lasts max 1-2 days but more importantly i need to be concious what the battery level is. With th eiphone i never really bothered as i knoew i would get at least 2 days if not more.

Still got audioOut_2 wakelock. Except that onr, everything is fine After Kernel update, greenifying and disabling Autostarts

Hi guys,
Last night I had 15% drop at the battery, wifi was off, gps was on.
From gsam i saw that the kernel drained the most.
Does anyone have any ideas how to avoid this kind of battery draining?
Few days after I got the phone I had 0%(!) battery drain at night and it was along few night, for some reason i cant reach same level of battery drain at night now.
Thanks in advance.
You have some weird apps keeping your phone awake, nova launcher? Have never seen that one in my list. Install betterbatterystats to see the wake locks in detail.

I don't think that's a wakelock list buddy, it's just listing which processes used the battery the most.
Apex, run this for a few hours and post a screenshot.
Betterbatterystats is an app that shows into detail the wakelocks, alarms, frequencies etc. Don't know the app you gave, maybe it does the same.

ok so here are the findings:
I froze news&weather since i dont use it and put taptalk on 3 hours intervals of checking.
I'll read more into BBS analysis to retrieve further information
anyone?
It doesn't seem like there are any weird wakelocks. How many hours of screen on time do you get?

Turn off your GPS.
Why do you need it on when you're sleeping? do you sleep walk? Don't answer that. Lol
I recommend downloading this app called "greenify" and find that app and hibernate it.

I also installed greenify, but it just doesnt seem to work well... every now and then, when I check on greenify, I need to re-freeze the Maps App, even though I didnt start it in the mean time.
Speaking of which, why does Maps keep the phone awake that long (or wake it that often) and drain so much battery at all?
anyone got an answer to this?
I've seen people here and there say they've seen this too, but no one seems to have an answer. My battery isn't lasting until work ENDS, a far cry from when I used to plug it in after work, at home, at 20-30%. It just randomly started happening.
Noticed this on both 4.2.2 and 4.3. I've tried .48 radio and .83, stock and PA, stock kernel and Franco, heard it's common on CM also.
Anyone actually know anything about this? I'd love to last an entire day not having to turn off sync when I'm not using my phone, and other battery salvaging methods.

your android os looks normal. seeing that you didnt use the phone much, your screen on percent is lowered. since your screen on percentage is lower, all others will appear higher than you would think they should be. but if your screen was using 50-65% of the battery as it would for normal use, then your other percentages would be lower. anyways, your android os is normal. what i would look for is an app in the background behaving badly, or disable a notification or two if you have many. if you have root, i would install greenify and then greenify a bunch of apps.
my android os usually hangs between 4-8%, but my screen is usually around 60%(with heavy use).

i never look at wakelocks, that is how our device is supposed to work. granted, occasionally an app will create a wakelock that gets stuck, but thats just bad coding on the app by that developer. watching wakelocks will waste more of your time than its worth. take control of your apps instead, dont let them run rampart.
Neither BBS or Wakelock Detector is helpful in diagnosing Android OS battery usage. Most of the time it shows as PowerManagerService.Wakelock in Kernel Wakelocks, and pages from google state that is it a sum of Partial Wakelocks adding to PowerManagerService.Wakelock. But there was one time I had a 15 hour wakelock from PowerManagerService.Wakelock and looking in Partial there wasn't anything really significant, most entries being 20mins or something at the top of the list, 10 minutes on the next, and so on.
Whatever it is, it's particularly bad on 4.3 both on my Nexus 4 and Nexus 7.
So I listened to some music for roughly 20 minutes in the car. Set my phone down to watch TV. Came back 45 minutes later and it dropped ~25%. This is WITH 3.5 hours SOT. android somehow still takes top spot. Help?

Everything was fine after the 4.4.2 update until a couple of days ago. I noticed a heavy battery drain during the night - approx. 20%. The conclusion I made: Android OS is back. The WiFi was on, but the router was off, so I though it might have something to do with it trying to establish a connection.
This past night I turned the WiFi off and left the 3G on. 10+ hours of wakelock from Android OS and 30% drain. So, what am I missing here?
The worst part is that those f"%^* from Android developers team has disabled any reporting from the running processes in the latest version.

You can use the stock google app to find what google app is running during the wakelocks. Just go into Settings -> Apps -> Running tab and see what google process are running. Then download and use "Disable Service" from the playstore to find and disable the suspect google apps.
My phone would stay wakelocked after a call or gmail check all because of gcm_google service. I disable it under Playstore services using Disable Service and my google wakelocks went away. Worth a try.
same problem here
misuse of wake locks can easily lead to energy waste
"Android os" usually is the kernel while "Android system" is, well the system. Try changing kernel, it fixed the issues for me.
Hit thanks if I helped you

Did you mean when the screen is off? Because obviously it status awake while the screen is on. But there may be an app keeping it awake. Make sure all your apps are trusted

I'd go for a wakelock detecting app like "better battery stats" or "wakelock detector" to see which app could be the culprit. "Greenify" could then be used to block that app from keeping your tablet awake.
I personally do have no issues with standby whatsoever. I'd say I lose about 3-4% of battery during the day on 4.4. (WLAN and sync on all day, but I'm taking it to work where I have no WLAN I could use). I guess I had the same mimimum drain on 4.3. So standby couldn't be better on N10 in my opinion.
I only had one issue so far, where at about 25% of battery left it suddenly began to drain like 10-15% an hour, thus leading to my N10 shutting off after about 2 hours. No idea what caused that drain in standby.
I second that, get better battery stats or something similar to see what's keeping it awake.

mhm ... will not install 4.4 if the battery life is that terrible. Did you guys control the typical Google apps, which usually like to eat a lot of battery?
I have this since 4.4.2 on my Nexus 10 and 7v2. Not on the 5. My N10 uses almost every juice for Android OS. Before it used 5% for 1-2 days for standby. Now 3 hours. See screenshot. Is this normal?
And it wasn't awake. See other screenshot.
After upgrading to 4.4.2, I noticed a massive battery drain, and then noticed that in BBS system_server is taking quite a lot, any ideas what it is and how to stop it?

Change settings in some apps how frequent they should update. For example, update every 6 hours and change settings in Location to device only that might help. On my phone, I had a battery drain to zero just overnight. I disabled Google+ because I do not use it and in Google Play Services turn location off. I also wiped cache and dalvik cache in recovery and the battery drain stops.

What I meant is not an off screen battery drain, rather it is an onscreen battery drain that is far more quicker than 4.3, with my phone under normal usage having a maximum of like 1.5 hours of on screen time even though idle drain is low.

And I am telling you that this doesn't prove anything.
At same screen, I have much more use for system server in comparison to you, but in real life there is no problem.
So, don't worry about this.
