See the attached picture, this battery drain happens every day and takes up more then the screen so I'll finish the day with 1.5 to 2 hours SOT while over 50 percent is sucked up by the OS. Any fixes?

How do I fix this
Sent from my Nexus 4 using xda app-developers app
This happens sometimes and seems to be triggered by the Location service (even with GPS off - but with wifi/data location on). It seems sometimes the phone is kept on a wake lock state which doesnt allow it to properly enter sleep mode.
When it happens, try rebooting your phone. That fixes it for me. It happens sometimes (about 1x every 2 weeks), and the reboot always fixes it.

I'm on CM7.1 stable. Haven't had battery issues for a while, but starting a few days ago I've been getting rapid drain with heating. Battery use screen shows that the phone is awake most of the time the screen is off, but it doesn't reveal which app keeps waking it up. I also tried Spare Parts to see if any app is hogging the partial wake lock, but nothing seems to account for it.
Any other ideas on how to trace it? Must've been an app that updated in the past 3-4 days.

Just to show how this looks, here is a screenshot of the battery screen.
Notice that I put the phone in airplane mode for the past hour as I was writing an exam, yet it still appears awake with screen off. The phone was warm when I retrieved it after an hour of the radios being off! Something is seriously wrong here.

I can only guess it is an application or service keeping your phone from going to deep sleep- also known as "partial wake lock" or something like that...
What to do? You can probably nail the culprit using some application like BetterBatteryStats (Market it, or look for it at xda's app thread- it is somewhere here). It will help you find who/what is keeping the phone awake.
I think that Battery Monitor Widget can also give you similar info.
You may need some help in the BBS thread to help you interpret the results as they are not always obvious or easy to tell who's the problem.
Right. What's confusing me is that nothing in the partial wake lock list is showing more than about 10 minutes of lock time, yet the phone gets stuck awake for more than a solid hour of screen off time.

I think I figured it out. I had a trigger set up in Tasker that resets the phone's data connection every time it crashes out with an error (and my carrier WIND Mobile does this quite frequently). On days when the battery was constantly draining, it may have been because the network was particularly error-prone and my trigger therefore kept going off. And each time it went off, Tasker must have flipped the phone into awake mode.
I've turned off the trigger for now, to see if it stops draining.
Since a couple of nights I noticed that my galaxy note can't last through the night, even with a reasonably well charged battery.
At some point I also accidentally woke up during the night and noticed that the screen was spontaneously on, showing the lock screen.
This morning I checked the battery usage, and took 2 snapshots.
As you can see, at some point the screen is activated and remains so for hours.
Does anybody have a clue on what could be the culprit, or how to find it out, I suspect some app, since this was not happening from the beginning of my gnote usage.
I still have the original os running (2.3.6)

Have you tried restarting or factory resetting your phone? It must be some application you may have installed. I haven't come across anything like this before.
You remove the charger from the phone without unlocking it. It is a known issue that prevents the phone to sleep. So next time first swype your finger on the screen to unlock it then unplug the charger, if not then restart the phone so it can go to deep sleep state.

Is the screen which stays constantly on the lockscreen a side effect of wakelock also? Did not know that.
The thing is that I use two batteries, so I almost never charge the phone itself. And since I replace batteries, I regularly reboot the phone (at least once a day). Does not seem to help.
I would prefer to avoid resting to factory defaults, one reason being that I would like to find out which app has such a malicious behavior.
But perhaps it's hard to catch the culprit, and I won't escape a reset (or a reverse chronological install of apps until the issue is resolved)

You can use Better Battery stats to find the rogue app. Its free for XDA members.

Ya know, I'd love to discuss these rom on the Dev page, but I'm still short a few posts to meet minimum posting requirements. :crying:
So, Hows the network connection with the latest build? Several of the customs that I've tried are oddly flaky at connecting to mobile data or wifi when coming out of sleep. Usually have to disable and re-enable to get data connected again.
I can deal with the deep sleep with WiFi issue (will have to train the kids to turn it off when their done with the phone) so that's not a real big deal.
Oh yeah. One more question. when my phone dies completely, I have to boot into Fastboot mode to get any kind of charge started. Otherwise the dang thing shuts down and then gets stuck in a loop. Very annoying. isolated experience or known bug with fix that I'm not applying?
Thanks folks.
The network connection is good on zoe no cuts after sleep
There is no deep sleep issue in this rom

Cool. Be testing it this weekend. Gotta start keeping a log of the rooms I've tested.
So far it's a pretty darn smooth Rom. WIFI doesn't power completely down. 40% battery drain overnight, compared to a few points with WiFi off. Digging the screen response on this one. WIFI to mobile network is very smooth. Damn nice work
New deep sleep test tonight. Discovered that wifi causes the phone to reboot every 4 to 5 minutes. That sucks!

I've testesd it too and got reboots, but not every 4 to 5 minutes. maybe one in 1 to 2 hours
Hi,
Been seeing reebots here as well, probably in the region of every 5 - 10 mins, not sure if it was wifi related though, just seem to happen when the phone is idle ...

When I'm at home or at work to get the app unlock wifi and no problem to fall asleep, and when I leave I turn off wifi it has worked, so far I have not had reboots

Probably your battery or kernel/rom if you are using a custom rom, sometimes my phone shutdown out of nothing but never happened something like that
