Terrible battery life

I have a huge problem with battery life on my G2. Everything started after playing with Kitkat custom roms and kernels.. With every single combinations (rom + kernel) I always have battery life problem. Yesterday I decided to go back to JB and see how it will works, but.. I have same issue on it.. I am using my phone for 19 hours and 2.19h on screen and 27% of battery left. What can I do to deal with this problem?

Also curious...

Few screenshoots from wakelock detector.

Here's an idea: Uninstall all that crap and test again.
Also, post English screenshot if you want help. This isn't a ->Insert your weird language here<- forum.

I'd clean reinstall a new ROM (I'm on cloudy G3 with native kernel) and just use Clean Master to help boost battery life. Mine is very good so far. Around 5 hrs of SOT and almost 3 days of standby.

To the OP,
Are you restarting your phone in either silent or vibrate? That's what caused my 1013 wakelock in the past. I always reboot without vibrate/silent on now, and have not seen this issue.
Secondly, game playing will use a lot more battery than normal. It heats up the phone and works the GPU/CPU. For example, my battery only lasts 3.5 hours with Ingress playing.
Third, looks like you have some Android OS wake locks. Do you have Google now/location settings on and reporting?

[Q] Start over or keep flashing? battery issue

Hi everyone,
I'm a bit new to this but bear with me. I got an S5 SM-G900A this week with OA1 loaded on monday night. After spending tuesday marveling at how much bloatware was on it and how horrible the battery life was I rooted and began freezing and uninstalling some apps. Day 2 with the phone was also very bad, it nearly died in 8 hours with less than 1 hour screen time. Today, Day 3, I began tweaking a lot of the settings to see if I could get it do better at idle, but again it barely lasted through the day. It took me a while to figure out the "WiFi always scanning" setting, but even once I got my phone to sleep, it didnt seem to make that much difference (no blue bar in usage manager). I've attached some screenshots from usage manager and wakelock detector, does this all look normal to the experts out there?
Should I just flash back to stock to see if I can get the phone at least making it to 15+ hours with light usage on the completely stock setup? I feel inclined to do this, because it SHOULD work bone stock, right? Or is it a waste of time and the stock rom is so bad I should just load something else?
Finally, if I did want to try going back to completely stock I could just follow the troubleshooting section of this post, is that correct? can I flash the OTA updates in the same manner using ODIN instead of sideloading from an sdcard? http://forum.xda-developers.com/att-galaxy-s5/general/how-to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120

flashed to stock
Just wanted to update for anyone having similar issues. I flashed back to stock using the "downgrade to NCE" file found on this site, then sideloaded NCE to NG3 and NG3 to OA1. That solved my problem and the phone now runs like a dream.

Improve Battery After Nougat Update

i have seen many comments in different threads about having poor battery life... i myself have faced this issue.. with my battery dropping like 5-7% while it's ideal to.. so many people suggested to full wipe my device but along with it i used a software BK DISABLER(SAMSUNG)...
i disabled all the apps along with samsung account(i checked shealth was still working after this but then i removed it seeing the number of services it had)
given in this link..
https://forum.xda-developers.com/galaxy-s6/general/safe-to-debloat-s6-threads-t3090383
please check the second cmnt by @lizaSB..it's more detailed and apps are easy to find.. whenever you disable a bloatware be sure to check you have disabled the services given in it(using BK DISABLER.. obviously)
I don't know whether a seperate thread has been created for this or not... but after nougat update this really helped.. my batter falls like 0.6 or 0.7 % perhour when it's ideal...
I know many scripts are availabel for doing this but that requires root.. this app doesn't requires root privilege .

I feel battery for the S6/N5 family improved with Nougat, while the S7 line battery was negatively impacted. Moving to a spare S6 I had, as I had to send my S8 in to replace my screen, I'm getting quite decent numbers for a 2-year old phone that was used for most of that time by my mom (she changed phones recently).

Diary of battery-backup !

So I decided to share my experience with this phone, day by day!
As you all know, this phone (3T) has very different SOT to everyone, I was always wondering why some people (including me) can't get long SOT as others, up to 7 or 8 sot!
So I make a journey to find what combo of rom + kernel suite me best. And I will post it on this thread. Let me know if you want me to keep this up!
Caution: this is my own experience with my own setting. So just consider this diary as a reference
Day 1 (27-07): I 've had this phone for a week! And didn't get a very good SOT on either OOS 4.1.6 or OP9,10 and 11. Hence I downloaded and flashed OP8 which was best for battery (got it from a lot of users). Also I used ong stock kernel and no tweak and greenify at all. And yes, it really impressed me. I got a superior battery for the first time.
Here are some screenshots for battery. I used wifi most of the time , just about 15m of 4g. Most activities was surfing youtube and facebook, and brave (I didn't use chrome at all)

Day 2 (28-07)

So brave is less of a battery hog compared with chrome? Used to use dolphin but found that it didn't always work that well.

a word of advice...remove that facebook app and use some alternative app and c the difference

battery is draining twice faster

Hey everyone,
my Note 4's battery (SM-N910F) is draining really fast. I bought 3 new batteries (1 samsung from their site and 2 rav power) and my battery still only holds for like 3 to 4 hours (instead of the whole day as before).
Can you help me figure out a fix?
Thanks !
Android 6.0.1 is running.
Version number MMB29M.N010FFXXU1DQL2.
Baseband N910FXXS1DQA1

3 -4 hours when using it? That is great. However, if standby is affected then you need to see what is running in the background and affecting the battery. Use BetterBatteryStats and or Gsm Battery monitor

no, 3-4 hours when almost not using it ! Before, the battery was lasting all my work day. Now at lunch, it's done.
I installed Gsm battery monitor, here's what I get:

Do a search on android system battery drain and try some of the fixes. Something is running causing the drain. Google or other backup or something constantly syncing etc.

Finally, I did a full factory reset and now the battery is back to normal!
