Massive battery issues

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.

Cannot wait til you update us!
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

Odd, mine seems to be a lot better battery wise since 4.3... You might want to use BetterBatteryStats to pinpoint the cause (maybe some wakelocks etc.)

Flash a custom kernel.

Yes, me too, battery seems worse than in 4.2.2. Or is it just because that I use it more now i.e. to restore apps etc?

Really? Oh no!!
I'm still waiting on my ota update

Im gonna go back to 4.1.2 because it has the best battery life which 4.2.2 and 4.3 doesnt have

me too. Really hoped android 4.3 fixed this problem ;(

been having this battery drain problem ever since 4.2.2
Do you guys have this drain problem in IDLE mode? because I do..
rough estimate, it drains like 7 to 8% in one hour when my device is in SLEEP mode..

But to all this, what apps or services seems to be draining the battery?
Sent from my Nexus 7 using Tapatalk 2

I don't know what your talk in about, I'm getting better battery life than I ever did before. I'm UV by 25 running faux kernel (u21), and clean ROM. I just removed all the gapps I don't use, and don't run anything that needs background syncing. Did you guys do clean installs(full flash via fastboot)?
I also turned off daydream which I am suspicious of, yet I have no proof that it does anything

Thats the problem, I hard factory resetted several times and leave it alone with no new apps
installed before.. disabled NFC, my mobile connection.. and still it drains like a leaky hose in idle mode..
some friendly ppl here suggested installing greenify and betterbatterystats and stuff..
but it doesnt really help me pinpoint whats doing the draining.. maybe because I am not sure what I am looking at..
end result, i even flashed (nearly bricked my nexus on several occasions too) and still the drain is there..
I thought my battery is dying or something.. but my nexus is barely 6 months old.. and battery status shows it as GOOD..
so yea, I am stumped..

Yeap.
I am having the same problem with the battery, the battery is spent very quickly, I have less applications installed and lately I have not used the phone to see if it was me and nothing. It may be because manually install the OTA?

Does the rule of waiting a few days/recharge cycles to get a true sense of the battery not apply to Nexus devices like it does to Samsung devices?

The initial battery drain after flashing can be attributed to apps conducting their first sync and the kernel "settling." This only takes a matter of hours at best. After that, one can get a fairly accurate idea of how their battery is being tasked.

I too face same problem, and the App sucking most of the battery is "Kernel (Android OS)", second one is "Launcher", "Phone" and "Android System".
Any suggestions solutions found for this battery issue?

Android OS wakelock draining battery

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.

Nexus 7 power spikes.

I'm not sure what's happening. My Nexus 7 remains idle most of the time, yet I get pretty bad battery drain and then when I check the battery history I see this. This happens during every battery drain.
Any ideas guys?

Wow, have never seen that on any device! Install Gsam or better battery stats if you are rooted to see what's going on. My best guess, it's a hardware issue.

Have you already tried reformatting? Kind of a pain, but that's the only thing I can think of.

Try contacting Google or the seller they might give you a replacement.

That happened to me once or twice. These spikes are only visible on the battery graph in settings app. I use an alternative battery monitor app from Google play and it does not show any spikes. Also battery life seems pretty in line with what other people report. I simply ignore them since they do not seem to affect battery life.
Could it be caused by the wireless charging functionality being triggered by other electronic devices in house?

I saw the same problem in the G+ community there, but it's Gelexy Nexus which updated to Android 4.3 recently

Hey everyone,
My Nexus 7 (2013) is having the same problem with battery graph. There are about 2-3 spikes to 100% in every discharge cycle.
I noticed this problem has been reported in different cycles, but no one seems to be able to give a definite answer of what the source of this problem is.
BTW, after a reset to factory settings, the problem still persists.
ANY idea why this is happening???

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.
