Galaxy S6 920I Battery Issues - Help and Thoughts - Galaxy S6 Q&A, Help & Troubleshooting

Hey guys, first of all let me make clear that I've been through every single topic available online on these battery issues, and I have tried everything but nothing works.
I love my S6 but its battery inconsistency is driving me crazy. I've got every single topic covered:
Location services and history off
Wifi sleeping on screen off
Uninstalled and disabled every single bloatware that Samsung offers
No facebook app
Screen brightness on 10% most of the time
Tried factory resetting and wiping system cache more than 3 times already
I was stock 5.0.2 and recently flashed stock 5.1.1 via Odin hoping it would solve my battery problems but it made my issues even worse. I get 2h SOT tops, and my device usually drains 40% of its battery when I'm in bed (11pm - 7am), even with Wifi/data off and all apps closed. Battery system monitor shows a 40% drop on battery caused by "Android System", and GSAM shows the same but with special drain for "Android System - celgeofenced".
I don't feel safe rooting right now and installing Wakelock because I've read a lot of issues related to Knox violation in the current rooting methods.
Any thoughts on that? I'm really getting to a desperate bottom line here.
Thanks.

I'm on a G920i Vivo - Brazil and I was gettin same battery drain as you. Unfortunately I only solved this issue making root with CF ROOT, TWRP, flash SUPERSU, flashed the DeepSleep zip via TWRP, wipe cache/dalvik and rebooted!
EDIT.: Deep sleep is gone after 2 hours, some app is using GPSD and killing my battery :////

Could you check if you have this option in 5.1.1 ???

Are you sure? The problem is 40% draining without even touching my phone. Does it seem fair based on your usage standards? Thanks

[Q] How to eliminate GTALK_ASYNC_CONN wakelocks?

I have a Nexus S 3G, and installed bone-stock, and got it to idle for 3 days 19 hours, give or take.
I wanted to try CyanogenMod, installed the latest stable (7.1), disabled Data Syncing, have a single GMail account, no apps installed and lose about 2-3% per hour battery life sitting still. I'm using the GladDOS 1.8 Kernel, which is what I used to get the 3 day idle before.
BetterBatteryStats shows that I have 11m23s of GTALK_ASYNC_CONN partial Wakelocks (this is over a 1 hour time period).
I used Titanium Backup to uninstall Google Talk, and still get the Wakelocks.
I'm going to re-install stock and re-verify stock idles fine.
Any ideas? I've searched high-and-low, and it appears it's a known issue, but I've yet to stir up an answer.
Anyone?
Thanks!

I know its been a few weeks guys and apologies for pulling this back up but i suppose its better than starting a new thread.
I have pretty much the exact same problem as plymptop above, i installed betterbatterystats and after only 2 hours its chewing through battery power and pointing to GTALK_ASYNC_CONN"my email address" /android_talk etc and beside this it says "Count: 94.
I had my phone returned to stock 2.3.3 a week or so ago and this wasnt a problem but it seems no matter what custom rom i install, i still get high battery consumption. Anything from 6-12 hours with little or no use.
Anyone got any pointers on what i can do to correct this? Thanks in advance.

Android System draining battery on lollipop, but only under wifi

the title says almost everything. I updated to last cmos12 release, flashed again, clean flashed again, wiped everything and fastboot super clean flashed again. nothing. Android system drains the battery on par with display. i have approx 3 hours cpu uptime for android system in a discharge cycle. but this behaviour simply disappears if i don't use wifi and only rely on mobile connectivity. ofc i have better battery stats and wakelock detector installed, so please ask me for things you need to help me understand and troubleshoot the issue and i'll provide them.
thanks in advance

I have the exact same problem, although I'm not working on a rooted phone. Working on LTE goes ok, but the moment I switch on wifi the phone gets very very hot and drains the battery. Other than 'Android system' I cannot see any other process draining.
no hot phone for me. i get lots of wakelocks but they're 1-2 sec each so nothing to worry about. the phone deepsleeps well too. but those 3 hours of cpu uptome for android system drive me crazy.
any suggestion out there ?
Most likely it is a bug from Cyanogen os 12.
As it is still an initial build, I think you will get a more stable build in near future.
I will suggest you to check the following option under wifi > advanced settings > keep wi-fi on during sleep option.
I have this set as always.
If you have the same then you can try with the other options.
tried but ofc i need data connection while sleeping and relying on mobile data is more power consuming so no, wifi has to be always active during sleep ^^

Try this, it worked for me. Wifi settings seemed to be the problem. Changed the frequency from 'automatic' to '2.4 Ghz only' in the advanced wifi setting.. Now all Normal. I almost returned the phone thinking of a hardware issue.

My N5 battery needs a replacement?

Hello everyone, there are few days now that I have some strange issues with the battery of my mobile phone.
First I saw that the life of my battery goes up to 3 hours, using data mobile, where previously it was about half day. Second, yesterday while I was trying to delete photos from photos app, (the battery was about 40-50%), my phone did a random reboot and the battery went to 1%. These kinds of random reboots I had it when the battery was on 15% but also on 30%. The most strange thing of all, when I had these kinds of reboots, all the saved wifi networks that i had, was lost (not always).
Here are some photos from the battery stats.

I want to mention that I'm running android 5.1.1 - LMY48B.
Does anyone knows what is the issue?
What do you suggest to do?
1. Make fix batter permissions from custom recovery?
2. Make a full factory image/custo rom?
3. Replace the batter of the phone?

If the issue keeps happening do a factory reset. Doing 1. doesn't help at all and 3. Is a last resort.

Terrible idle battery drain!

I have a terrible battery drain when my phone is idle. Tried everything, but nothing solved it. Ever since Lollipop I have this issue.
Clean flashed MM and still nop. Flashed ElementalX 6.04 yesterday which still couldn't solve it. This is frustrating :crying::crying:
I have disabled everything too. No Wifi, data, bluetooth, location...etc (My phone is not a smart phone anymore)
Only adaptive brightness is enabled.
Yesterday I fully charged and went to sleep to find out it has drained 28% after a 7 hours sleep. Removed all the unpopular apps (suspicious apps) as well. BetterBatteryStatus says my phone has been in DEEP SLEEP throughout the whole time too.
Please give me a solution

How old is your phone?? You might need to replace the battery. Especially you've already done everything from kernel, to clean flash to disabling apps and settings
your bstats also tells no abnormality? how about its partial wakelocks? can you post those so we can check it out?

According to BBS my phone has been in deep sleep throughout the whole time. I'm assuming its the battery, I need to replace it may be.
I charged my phone again. I will post partial wakelocks too in few hours time.
Thanks alot
Even though it may not make a huge difference but you can try draining the battery out to 0 (until the phone can't stay on even after a force power on) and a full charge (30 mins to an hour overcharging after you see full battery indicator).. Gluck.
I replaced my battery, I was getting hard reboots as well. But wow with a new battery and marshmallow my nexus is like a new device.
99% no or unknown signal.
That could be the cause of your drain, when the phone has no signal or poor signal it will use a lot of battery to keep the connection alive. Set aeroplane mode on

Drastic effect on battery after downgrading to Lollipop

My LG G4 H818P came with Marshmallow 6.0 installed. It had bugs, unrootable and bad battery life. So, after a week or so, I used LGUP to flash a stock Lollipop kdz and then rooted it. Both of the procedures went just fine.
But the battery life has worsened drastically, let alone improve. For instance, I checked the battery at 92% before going to sleep and woke up in the morning with 71% but the whole time the screen was turned off and nothing was going on background. The battery doesn't even last 1.5 hours when I'm watching a movie or browsing the internet.

have you calibrated youre battery....???
charge your phone 100% and
calibrate it using battery calibration app from play store
it requied root
when youre phone is full charged 100% open this app and give it root acess and click calibrate
after that unplug ur charger and reboot your device
and discharge youre battery with normal use and after discharging to 10-5% charge it again... and its done
and if you want more battery juice
use these apps
amplify battery extender(requires root & xposed frame work)
powernap (req.. root & xposed)
if you dont have xposed
use l speed app download it from google play and toggle main tweaks (just need root)
see the magic when you left your phone at night for 100% at the morning it will be 98-99%
its awesome app just try it (it supports all devices)
Thanks a lot. I didn't try calibrating because I thought a decalibrated battery would show weird & incorrect percentage. Anyway I'll let u know after I do it
