You can see some strange kernel wakelocks in my screenshot.
is there someone who can explain them? Can't find any useful information.

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?

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 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?

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
Snapchat, other camera apps, and even sometimes stuff like Mixcloud/Soundcloud crash at various frequencies. Are there any known workarounds? If not, is there another kernel that has the battery saving potential of EX Kernel that doesn't cause these issues?
This shouldn't be kernel related and if you are 100% sure it is, grab a log and post it in @flar2's thread so he can identify the issue and fix it.

This is not a elementalX problem. A kernel has nothing to do this at the beginning. And I don't have any issues at all.
I've just seen on my A7 in BBS this wakelock. Can someone tell me about it? Any answers will be appreciated...
