I have the zen kernel on the preset values on all the Roms to see how it runs first.

There is a patch update as well, did you flash that?

Okay, I'm gonna try replicating your situation. I'll flash the kernel you did. Anyone else having these problems? I've just been running the stock kernel and haven't had any problems. I'll let you know what I find.

Can you post a link to the stock kernel? I'll use that to see if it works...

Umm if you reflash the ROM you should get the stock kernel. It's included. Let me know if you need it by itself and I'll get it for you.

I'm saying just do a dirty flash.

WiFi craps out on the dirty...let me try the kernel by itself.

Okay, either do a wipe and flash the ROM again, or just stay on the kernel you're on right now, since I don't have the kernel by itself. I'm going to do a test with battery stats to see exactly what is draining the battery or if it is on the stock kernel, and then I'll get back to you. Seems like you're the only one having this problem at the moment, so bear with me here, and I'll see if anything is making my phone stay out of deep sleep as well with the stock kernel.

If anyone else is having battery problems, please let me know, so that I can make sure its not just clj575 who is having the problem.

Sorry you're having problems man, hopefully we can get this figured out. Thanks for your patience!

Okay, here are the results of my tests. These are the stats of my Galaxy Nexus, running my ROM with the stock kernel included with the ROM, although I don't think it makes a difference depending on the kernel.

Here are my initial tests:

BetterBatteryStats-2012-12-20_withmaps.txt

If you take a look at this area:

Code:
NetworkLocationLocator (com.google.android.apps.maps.Maps): 3 m 20 s  (200 s) Count:342 2.4%
SignalCollector.ScannerThread (com.google.android.apps.maps.Maps): 1 m 42 s  (102 s) Count:57 1.2%
SignalCollector.Scanner (com.google.android.apps.maps.Maps): 1 m 40 s  (100 s) Count:1313 1.2%
According to this, most of the wakelocks that occured during my around 2 hour test were from these processes, all of which are part of Google's Map application. Also, if you look at this area:

Code:
==========
CPU States
==========
350 MHz (): 2 h 14 m 43 s  96.6%
700 MHz (): 4 m 36 s  3.3%
920 MHz (): 2 s  0.0%
1.2 GHz (): 1 s  0.0%
Deep Sleep ():  -0.0%
There is no deep sleep being achieved. Now look at this:

Code:
"gps-lock" (): 2 h 18 m 40 s  (8320 s) Cnt:(c/wc/ec)0/0/0 99.5%
From this data, it seems that the Map application looking for my location all the time is the cause of the power drain on the battery. So I uninstalled it. Then I used Speedtest to grab a GPS lock, then ran another 30 minute test. Take a look at these stats:

BetterBatteryStats-2012-12-21_nomaps.txt

If you look at this area:

Code:
==========
CPU States
==========
350 MHz (): 1 m 4 s  3.1%
700 MHz (): 24 s  1.2%
920 MHz (): 1 s  0.1%
1.2 GHz (): 2 s  0.1%
Deep Sleep (): 33 m 10 s  95.6%
We are now achieving deep sleep. So it seems that, at least for me, Maps is causing these issues, not the ROM or either of the kernels we are running. I hope this helps your issue, and it definitely helped me understand the cause of this issue.

One more thing. I was poking around the interwebs and found this thread in the AOSP known issues list:

http://code.google.com/p/android/issues/detail?id=34458

This seems to confirm what is happening here. Please let me know if this helps!

Oh, I almost forgot! I couldn't have done any of this without the help of UBER. He really knows his stuff when trying to test these kind of problems. Thanks dude!
