I installed Quantum 3.15 ROM a few days ago with decimalman's kernel.
I am getting battery drain with my phone doing nothing at a rate of 7-8% per hour. BBS lists the PowerManagerService.wakelock at the top of the kernel wakelock section. A little research tells me this is a placeholder for all partial wakelocks. Problem is, partial wakelocks lists nothing. So I have no idea what is really going on. Can anyone give me some advice where to look next?

+1 Having the same question. About to post but turns out you have already post it :good:
Exactly the same situation tho my battery did not drain that much but still found the powermanagerservice and main kernel wakelock had been running very long time, while partial wakelock had very few awake. Any method to decrease the running time of powermanageservice and main without rooting your device?
bump for the answer!
Anyone got it fixed?

I am experiencing the same, was running doom v10 before and it would consume 1% per 2-3 hours. With v11 it is 1-2% per hour. Have checked cpuspy and it is running 98% in deepsleep and battery history only show the usual cell standby as power consuming.
Have only been running v11 since yesterday but will probably go back to v10 due to the battery drain.

Because I haven't written 10 posts yet so I'm unable to post in developement's topic..
Yeah, I have this problem on My Xperia Ray since I use The Latest DooMKernel... The Kernel drain battery...
user NeoCream wrote about this issue in the doomkernel thread..
I am a happy owner of HOX. everything seems to be perfect except the battery drain..
Either Android OS or Android system consumes battery like hell...
After charging the phone for 100%, i just unplugged it and after 30 mins battery was 73%...and battery temperature was freaking 50C which is like 120C for batteries!!!!! I restarted the phone which made the temperature worse...then after few mins again restarted and now the phone is going in deep sleep..this has happened many times and surprisingly batterystats says there is no specific culprit..just Android OS or Android system.
I read somewhere that it is actually Android bug and google are trying to fix it..but why does it happens randomly? And this problem normally happens when battery is fully charged...
btw i am on ViperX 3.3.8 and on stock kernel
Any help would be appreciated!
Thank You
Rom? Kernel?
ROM kernel details updated on 1st post...btw viperx3.3.8 with stock kernel
This is also happening to me Im also using viper 3.3.8 on the kernel provided by Venom, Im gussing its a bug on 3.3.8
BetterBatteryStats might help you identify what causes this drain.

Thanks for trying to help but I have already mentioned in the thread that it is not saying which app is causing problem..just Android OS and below that Android system
Heres the easy way out, look at my signature, open the link , there you'll see the guide for ultimate battery on HoX , And also there is a link for WAKELOCKS guide. If you do decide to follow my guide but before that check your wakelocks i ensure you that you'll be hiting minimum 5 hrs screen time with heavy usage ( no gaming )
Today's usage as recorded few hrs ago...
total 4h 37m on battery from 100% down till 43%...3 mins data on only..onle 1 call..2 texts..thats all..wth...will be posting screenshots soon..

Sorry I thought you were talking about the stock battery stats. Have you looked at the kernel wakelocks and partial wakelocks sections? That's where you'll get the most useful information.

Hey guys
I recently installed CM12 (official version) but i noticed that it eats up alot of battery alot quicker than my stock ROM
i installed better battery stats and started recording stuff but idk how to read the information it provides
can someone help me?
Thanks
You could also try a cpu app such as no frills cpu to set the min and max frequencies.
I don't want to mess with clocks till I have expended all my other options. Do you guys know how to use the information betterbattery stats record?

Set BBS to show stats since Unplugged.
Charge your device so that it is fully charged just before going to bed.
Unplug and let it set idle overnight. This will let you know about background processes consuming battery, as opposed to you actually using the phone and consuming battery.
First thing in the morning open BBS. Click the share icon at the top left of the screen. Select the Text Dumpfile option and then Save. You could then take screenshots of the BBS pages; especially Partial Wakelocks, Other, and Alarms.
There are active threads with participants who are very familiar with interpreting the BBS results obtained.

You could also try dkp kernel. Search the forums here. I've heard you can get better battery life with it on cm12.

hi.my device asus_Z00AD is on latest firmware,rooted and xposed installed.everything is going fine except battery life which is pain.it is worth to mention here that i use amplify,greenify and powernap also.i have noticed that android os drains much battery in my case and while digging deep i found cpu never ever sleep and further battery manager showed that main culprit is many kworker/u.so i hope that someone of xda family can help me to solve this problem and it can help others too.i have attached screenshots with this thread.(i know network in my area is like ping pong ball :laugh: )
Hi all!
For those who have donated to the Amplify version, which wakelocks have modified that does not compromise the stability of the system?
I mean those wakelocks who are under "safe limit".
Thank you
bump
I hope that's not forbidden on XDA.

Screenshots of what I have so far are below but I'm still getting 15% wake while screen off. I was getting 40% when freshly rooted on stock ROM.
What have you limited/disabled? How is your deep sleep percentage?
Jump to the amplify section: http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
Alot of the recommendations are safe and I used it myself. The only ill effect is for whatsapp it shows me as online until that alarm/wakelock kicks in. I modified it so it shows it accurately. Otherwise the rest had absolutely no change except for better battery life
