Noob question. Does the kernel have anything to do with battery life? Me and my wife both have a note 3. Mine is rooted hers isn't (4.4.2). Her battery life is great but Im not having any luck at all. If I charge my phone over night i wake up the next morning with 92% AND ITS STILL PLUGGED IN lol. Its like it stopped charging in the middle of charging. I would then have to unplug it and plug it back in for it to charge completely. through out the day I will get a full day but around 10 pm I would be at 30% or less with moderate use. Now thats ok but for this phone I should at least be at 50% with moderate use right? My kernel is 3.4.0-257432 Sat Jan 4 and hers is 3.4.0-722276 Sat Mar 15. I've used 4 different roms including DK 2.0 and DKX (Which I Love) and its the same thing. I've just stuck with the battery life. is this normal? Thanks for listening guys.lol
Since your GN3 is rooted, I assume that you are running Jelly Bean 4.3 since no one has rooted 4.4.2.
If so, you might try SafeStrap 3.71 and X-Note version 7. I had battery drain problems running the later AT&T 4.3 versions after the OTAs this year. After phone calls, my battery drain was at least five percent per hour. It used to be less than one percent per hour.
With X-Note v7, overnight I see 0.25 percent drains reported by Android Tuner. During a normal day with 25 minutes of phone calls, email downloading every four houses, some texting, and checking sport scores, I usually have 90 percent available at the end of the work day.
One of the biggest causes of battery drain is the dreaded wakelocks. They keep your phone from going to deep sleep and saving battery life. WakeLock Detector from the PlayStore works fine. I found that diagnostics.client.wakelock and NlpWakeLock. The latter can be stopped by turning off Location services. CPU Spy can show you the Deep Sleep percentage you are getting. At night, my phone reports as high as 98 percent Deep Sleep.
Go to this thread in XDA to get from Safestrap KK to JB.
