[Samsung Galaxy Nexus] XaosNZI:
Hey guys!

So a couple of days ago I fresh installed 4.3 onto my gnex after my phone kept downloading the 4.3 OTA update which totally killed my mobile data.

I am running on Paranoid Android 3.95 with a Golden 4.3 kernel and so far my battery life had gone worse compared to 4.2.2

I've installed BetterBatteryStats to scavenge for the issue and I've found that NlpCollecterWakeLock was keeping my device from deep sleep.

My phone was running for 4h 53m 44s and NlpCollectorWakeLock was running for 4h 19m 26s (!)

​

The wake lock was preventing my phone from getting into deep sleep and instead my phone ran on 192 MHz for 4h 14m 8s and I have no stats for deep sleep in BBS.

​

From the Battery pane in Settings, Google Services was eating up 28% of battery while keeping awake the phone for 4h 27m 6s.

Also, my phone has Sync OFF, NFC OFF, Data OFF and Greenify installed to automatically kill unwanted processes.

​

I ran through the forums and found out that people were suggesting to turn off Location Reporting and Location History in Google location settings but some people weren't having problems with Location Reporting and Location History.

Also, I want to ask about the Android Device Manager thing... I currently have 'Remotely locate this device' checked. Does this impact on battery life? I mean, if you enable this would your device pull location data and somehow sends it onto Google's servers? I don't really know how it works but it concerns me for some reason.

So, anybody with these issues?

***UPDATES***

Aug 15 / 2:43PM GMT+8 - I've disabled 'Remotely locate this device' in ADM and turned off Location Reporting and Location History. I'll recharge my phone to 100% and let it run through the day with WiFi connected and with medium use. I'll update here when I get results.

Aug 15 / 6:42PM GMT+8 - After disabling 'Remotely locate this device' in ADM and turning off Location Reporting and Location History, it seems to have improved. Google Services is eating up 4% battery and it has only kept my device awake for 2m+. But now Android OS is keeping awake my device for 2h 30m+. At this point, I am extremely lost and confused. I might be doing another idle+WiFi on test but -8% over the course of 2 hours is still high.

ADM location settings disabled, Location Reporting+History disabled. ​

Aug 15 / 9:54PM GMT+8 - Okay guys, so I've rebooted my phone and cleared my battery stats to run another idle+wifi on test and my problem is now resolved! (I think...?) :victory: Also, my phone was previously running on 192MHz ALL THE TIME + NO DEEP SLEEP and now it's gone. I've set my CPU frequencies to 384MHz Min and Min Screen On. Trickster MOD and BBS are registering Deep Sleep again!

​

Also, the NlpCollecterWakeLock is totally gone from BBS. Huzzah.

​

Here are my battery stats over 3 hours:

​

So I guess it's fixed for now. I'll update if I get weird stuff again.

====================

HOW I FIXED MY PROBLEM (for now):

1) Launch Google Settings > Location

2) Set 'Location Reporting' and 'Location History' to OFF

3) Launch Google Settings > Android Device Manager

4) Uncheck 'Remotely locate this device'

5) Set CPU Min and Min Screen On frequencies from 192MHz to 384MHz (had a problem where phone didn't enter deep sleep, stuck at 192MHz [maybe deep sleep freq?], Trickster MOD and BBS wasn't registering any Deep Sleep times, but Settings>Battery graph showed that it wasn't awake, weird.)

6) Reboot

It's kind of annoying that 4.3 introduced this problem. Had perfectly no problems with 4.2.2 and this makes me want an iPhone more...
