Hello, i have been some days seeing this annoying wakelock on my phone. I've search in internet some information about it but i haven't found any relevant information. It's getting me crazy and it is draining my battery while the phone is locked. If someone could help me with it please do it.
I refear to job.delay wakelock, it is located on alarms in better battery stats app.

Hello everybody
I have problem with battery drain when my WiFi is on. During night my battery drain 1-2% which is great and WiFi is off, but when I turn my WiFi on and just read news with some app it goes down 5-10% in like 10-15 min. I'm not rooted because he is still in warranty and I don't wanna lose it just yet.
I've searched the forum and I have just found that people have problem when WiFi is off and battery drain like is on but that's not problem here.
Any suggestion?
Thanks.

To diagnose this you would need an app that monitors what it is that is draining the battery.
Try installing "Better Battery Stats," open the app once then close it. For a few hours, use your phone like normal or in a situation you want to diagnose. Then go into Better Battery Stats and post a screenshot of "Kernel Wakelocks," "Partial Wakelocks," and "Other" here so we can take a look.

Other apps which are good to see what is draining the battery are GSam Battery Monitor and Wakelock Detector.

Wakelock Detector: https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
Do the same with these apps as I said with Better Battery Stats and post screenshots from them.
Good luck!
Thanks for quick replay. I'm using GSam Battery Monitor for 2 weeks now and here are the images I think it could helps.
If you need something more just ask.

Those pictures look pretty alright. I'd say you aren't suffering from the Android OS bug a lot of other people are suffering from. What is your screen on time? 32% battery left after 6½ hours is quite a lot of drain, it seems as though you must have had the screen on almost the entire time. Looks as though Facebook and Google Services are the ones draining your battery. You could uninstall or deactivate sync for Facebook for a while and see. Google Play Services issued an update some day ago which is rolling out which should fix battery drain as well. You'll have to keep a lookout for that one.
I'm having major issues with my g2. I've tried a factory reset, but no matter what I do, the phone's battery drains quickly and the "android os" stays awake for 3.5 hours, even though the screen has only been on for two.
I have both BBS and Gsam, but there are so many different wake locks listed, I don't know what's normal and what's not. I've attached my latest BBS logs. Can someone with expertise help me out with some feedback?
Most your wakelocks seem to be location services... That can be decreased by disabling google now, google location reporting and alternatingly using unbounce xposed module
Hey there,
Recently after patching to 4.4.2 on Telus, I have found that my S4 has been draining quicker than usual. I tend to only get 10 hrs charge on it now, but the odd thing is that occasionally when I unplug it, it will go from 100% to 77-75%. I'm not quite sure what the cause is, but I'm guessing it is battery wear due to heavy usage? I am just curious if this is the case before I consider getting a new battery for my phone.
Any help that you guys can provide would be greatly appreciated.
There are countless threads on battery. Start with the obvious, open battery settings and see what's draining your battery. Restart/pull the battery.
Are you rooted? Get wakelock detector from play store. Figure out if you have any apps that cause wakelocks and then fix it. Or if you're getting poor signal in your area, that can lead to battery drain.
Try apps like deep sleep battery saver if you have wake locks. Or use tasker to control your radio if you get bad signal in certain areas.

Mostly says screen and kernal, been using Lux to try and keep the screen brightness down, but it has been draining faster than usual. Have tried restarting/pulling the battery but to no avail.
Not rooted, and have been keeping an eye on signal, but the drain occurred even when at home with full bars.

I don't currently have a SIM on my Nexus 7 32GB 3G, so it's constantly on Airplane mode. However, these times are really weird, especially when I only use it about an hour or two a day nowadays. Is anyone able to point me in the direction that I need to go to find out the root cause of this battery drain?
Running CM10.2.1. Previously this battery statistics were also observed when I was running ParanoidAndroid.
Any help is greatly appreciated. Thanks!
You need to see and post if you want, the times waking device and time held awake screens from Gsam. They are the screens that should show the culprit.
Found it.

Googled about it and found this to be a widespread issue... was not able to find a solution to it though. Any recommendations?

How to fix mc_fastcall eating battery
I have a problem where Android OS is a bigger battery hog than it should be.
Recently I came across a problem where Android System was my main battery user. This problem was accompanied by my phone constantly being hot and laggy. I found a thread showing how to use "Show CPU Usage" under Developer settings to point out the specific process that's draining my battery. Turned out, it was secure_storage_daemon.
Two days after fixing that problem (by formatting my micro sd) similar symptoms started showing up. This time the culprit was mc_fastcall.
I did some searching but couldn't find any solutions to this problem.
Can someone please tell me what is mc_fastcall and how do I stop it from eating my battery.
Thanks
