[Q] GCM_LIB Wakelock - Nexus 4 Q&A, Help & Troubleshooting

I was wondering if anyone might be able to shed any light on this, my N4 is awake ~90% of the time, and I can't figure out why GCM_LIB is causing it, or even what GCM_LIB really is. Pretty frustrating. This also happens on franco r213. Any help at all would be very much appreciated, as this is started to really pee me off.

Backlight never shuts off

Something is really the matter with this phone. It does a lot of odd things and I don't know why. But this one is important because it drains a full battery in a day.
If there is something in the registry that maybe can solve this problem, I would very grateful if someone could help turn this backlight off!
Thanks!

Help identify this wakelock

Hi all,
I have been slowly eliminating my wakelock issues and I am stuck on the last one "WifiOffDelayIfNotUsed". Can someone tell me what it is and what's causing it?
It sounds like some sort of delay to turn off WiFi when screen is turned off.

WIFI automatically turning ON when phone battery hits 15%

as soon as my S5 phone hits the first low battery warning at 15%, the WIFI automatically turns on
makes no sense since that would drain the battery even faster
already checked all setting to make sure any auto switches are off
anyone else heard of this problem and know how to keep the wifi from turning on by itself?
nobody?
ok in case anyone else runs into this, i figured it out
after nobody replied i figured it had to be an app i had that not too many people use
after uninstalling one by one when my phone was hovering around the 15% mark, the culprit turned out to be:
prey anti-theft....a useful app, but now useless

[Q] Unusually high Held Awake time & Android OS usage

You can see my battery stats here: http://imgur.com/a/5y9pY
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?
This thread has some talk on that wakelock...

Phone won't enter deep sleep....

Setup: running latest stock image (mhc19i). Rooted, xposed, ElementalX kernel with ghost pepper script, and I run naptime with aggressive Doze.
Issue: fell asleep with my phone around 50% battery remaining. Woke up seven hours later and it had 30 something. I typically don't see more than 1-2% idle drain over night so this got my attention. I checked better battery stats and I obviously have a wakelock issue. Not sure what it could be. Powermanagerservice was running at something ridiculously high, like 96%. Audiomix is the other wakelock running rampid. See screenshots below. Any input appreciated!

Have you tried rebooting and then monitoring it to see if it happens again? It could just be a one-time bug, you'd need to reboot to confirm that though.
I was thinking that as well. I did recently reboot. I'm going to accumulate a good amount of up time and then check the stats again. As of now, battery drain seems to be normal.
Something is still keeping my phone awake while the screen is off...

I've seen this Audio Mix wakelock happen before on the OnePlus One, from memory I think it was kernel related, so switching kernels might be worth a try. You could also try using Wakelock Detector to see if it'll shed any more light on it, maybe it's an app rather than the kernel.
Hmm....think I solved my issue. I got audiomix wakelock to completely disappear. Simply going into settings and turning off all notification sounds did the trick. For me it's not an issue, however, for others who don't constantly keep their device on vibrate I could see this being a massive dilemma. I'm assuming "powermanagerservice" is a normal wakelock to observe?

Yes, powermanagerservice is perfectly normal for when the phone is in use (or some background operation is running). You'll see it roughly correlates with your screen-on time.
I recently decided to check the huge battery drain during night and I found out that my phone would not go in deep sleep. Can anyone please help with that? Also, the 'jio' app I have been using was installed 50 days back and the battery drain similar before that too. Would be really great if I could find a solution for the deep sleep issue. I am trying to load the screenshots of betterbatterystats but not able to.

Use gsam form the play store to find out what app is keeping your phone awake.
Uninstall said app.
