Anyone who is having battery drain on 4.3 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Just an FYI -
I was having battery draining problems with my stock MK2 4.3 rooted. I had seen several forums with users complaining about the same thing. Long story short, I had messed up my phone trying to mod it and had to Odin a stock ROM. I Odin'd stock MJA, OTA updated to MK2 and re-rooted. The unexpected benefit to this was I how have outstanding battery life. I have absolutely no idea why this helped, but I figured I would share it so that it might help others.

I did pretty much the same thing you did and am noticing the same results.. Great battery life.. I had 4 hours of screen on time when it hit 5% last night ..Pics are of today's battery life so far...

Sudden Battery drop with Gingerbread but works fine on JB.

Hi,
I have a Defy+ red lens. The problem is I am getting sudden battery drops with Gingerbread and it doesn't even last for 20 hours but it works fine with Jellybean 4.1.2 and last more than 40 hours.
The thing ig Jellybean is really very slow on my phone and gingerbread is very fast. The only thing keeping me from keeping Gingerbread is this battery drop.
I searched and tried several battery fix and calibration but nothin worked.
Its not battery issue as the battery works better than expected with Jellybean. Can someone suggest any solution so can I use Gingerbread with a little battery backup.
P.S Both Gingerbread and Jellybean are Quarx's build

How to get kitkat on N4?! I thought its not out yet!!
Hey lex,
Try downloading 'BetterBatteryStats' from XDA, and 'Wakelock Detector'. Both of these apps can help you pinpoint what is draining your battery. With 4.3 I found that I had a kernel wakelock issue that was fixed by keeping wifi on. Best of luck!

Note 4 N910C very bad battery life

I'm running on 5.1.1 COJ5 latest for my country:
http://www.sammobile.com/firmwares/download/60110/N910CXXU2COJ5_N910COXX2COJ2_VIM/
So if you are on a stock firmware and you have good battery life i would love it if you told me what your version is so I can try it out. Or maybe if you have other suggestions.

Mybattery is similar to your issue I'm going to root my device this week and use a custom Rom but I'm told by many people to replace battery and don't use diffrent kind of chargers. I hope someone know the best way to keep this phone running cool and processing values decrease when focusing on 1app like reading in appygeek so battery extends longer. I'm pretty sure this can stay a full day if just browsing, reading and phone calling, chatting and some small video clips in whatsapp. Because right now I'm charging phone 2wice a day fullcharge. Zzzzz

Bluetooth battery drain since 7.1.2

This is crazy I've done so much to try and figure it out and want to see if anyone has ideas.
Factory reset countless numbers of times. Even tried not doing restore.
Replaced my device because I thought it may be hardware.
Been on stock, on most custom ROMs, and all the same.
On PN now and rooted.
Just installed Better Battery Stats but nothing from there yet. Will monitor.
It looks like BT share is always using the battery. I don't think it should be.
Any suggestions or ideas?
Yes I have some apps but nothing crazy and all the same as I had on 7.1.1.

Terrible battery life

Hey guys I am currently running official BQC5 firmware which I got through OTA update on my G930V. I have noticed that on Nougat it's battery life has become terrible. You can judge the battery life by taking a look at the attached screenshots. I have disabled various bloatware apps which I don't use using package disabler pro. Other than this, no modification has been done on my phone. I also keep display brightness below 50%.
So kindly suggest me how can I make the battery last longer again.
Thanks and Regards

Did you use the battery optimizer option? I have mine set to the middle setting. It's in the battery section of settings. Try that and see how it works.
