[Q] Need help eliminating battery drain which seems caused Android subsystems

I have a 1.5 year old T-mobile LG G2. It used to have great battery life and after a day of light usage I had 70% or more battery left!. However, these days it drains battery like crazy. I hardly used it today, and it dropped to 8% from 100% in 9 hours
From the battery usage I have been collecting using Gsam (it was recommended by some online websites) it looks like build in Android sub-systems are ones draining.
My battery overview shows 21% used by phone radio and 10% by wifi. However when you look at details, I hardly used my radio (8 MB) and only 84 MB of Wifi data. See attachments.
62% is used by Apps and a whole 40% seem be from build in system App (Kernel, Google services, android system, system manager). From the screenshots I already uninstalled the smaller apps with the X sign. See attachments.
What other steps can I take to investigate this problem? Any suggestion on what to do remove my battery drain?

Why is my Galaxy S6 edge plus's battery draining so fast?

I recently bought this phone and I have noticed that the battery is draining fast. The battery level dropped by almost 10% in 15-20 mins while I was just doing normal texting. I have used the phone in safe mode as well and in standby mode the phone just lasted for 24 hrs as opposed to 3 days of standby time as claimed by Samsung. So I was just wondering if there is an issue with my battery or with the phone or if this is normal in S6 edge plus?
Stats according to GSAM Battery Monitor,
Used 85% in 20 hr 10 min
phone - 0%
Screen - 2 hr 47 mins - 25%
Phone radio - 20 hr - 6%
Wifi Active - 20 hr - 3%
Held awake - 7 hr - 1%
App usage - 64% (With Android OS - 24% and Kernel - 10%)
I have already tried restarting the device and the problem still exists and always keep location off. And in terms of data I keep my wifi on and the apps that I use r only 3-4 like facebook, whatsapp, instagram. The main source of battery drainage is android system and screen. I was wondering is it possible that there is a problem with my battery/hardware and I should get it replaced? or it just could be a bug in the system that can go away after the marshmallow update? Coz originally I thought that there is a problem with my battery but now it seems like it could be an Android OS bug.
Had similar issue.
I had similar issue,
Looks like Samsung software's were using lot of RAM and battery.
Disabled most of the apps which I don't use and also the Microsoft stuff.
NFC off. Smart stay off,
Now battery backup is good.
I think everyone is having the same issue with the battery. If the marshmallow update doesn't fix all the issues I'm having I'm jumping ship. I'm at 77% with 58 m on screen time

Yes. I guess u r right, a lot people r complaining about the battery issues. For me i just used my phone for 45 mins with the same screen time and got down to 79% from 100%.
But its surprising to see how some people r getting tremendous battery performance with the screen time of almost 6 hrs in one full charge. Which makes me feel is there a problem with my phone hardware or its just an android system bug.
I have the same problems and I did a lot of testing. I am only getting as much as 10h of TOTAL battery time (I am not talking about SOT). Get it out of the charge at 7~8AM and have to charge it 5PM. I did a post about it here.

S4 major battery drain

Hi guys so I have a s4 i337m running Android 5.0.2 and recently I have been getting extreme battery drain. It draims around 3% an hour when the screen is off and seems to be awake more than half the time! I can get may even 2 hours screen on time even with my 3000 mah zero lemon battery. I have factory reset twice and even reinstalled the rom and it if anything it's gotten worse. Any ideas.? I do think want to downgrade to kit kat unless if have to.
Not enough information from you to allow anyone to help. Install an app like Better Battery Stats, run it for a day, then post a log so we can try and help.
I have been using gsam battery monitor for a couple of days and the android settings as well. I don't now how to put pictures in this thread but android is and system are at the top. Around 35% screen 20% android os, 15% android system 10% other apps and the rest unaccounted for. In GSAM I get around 70% app usage with both android is and system taking around half that. In the system settings it also shows that I have severe wakelock. I was in an area with no service at the but that is not the problem. I am on wifi 90% of the time. And almost always have a good cellular connection when I'm not.

LG G6 - Battery drain by System Android and Kernel (Android OS)

Hi, I can't figure why System Android and Kernel (Android OS) is always on top of the battery usage list. I can't even get 5h SoT and it's hard to hit 24h on single charge. I don't use Facebook and other draining apps and of course I'm using Greenify and Aggressive Hibernation.
I also noticed that battery drain is almost the same when I'm browsing web and playing Asphalt 8!!! Is it normal on this phone?

Extreme battery drain by android system

Hi friends....
I have the exynos version of s7 edge and am suffering extreme battery drain... when the phone is off it still costs around 2% in one hour and sometimes without even using the phone feels hot in hand.... i have tried everything that was on youtube and all the methods in the xda thread.... twice factory reset my phone and tried resetting as well but the results are same after i update the apps on my phone....
The major reason for the battery drain was 1) wifi active around 37% and 2) apps usage around 61%....
But i couldn't find out which apps were causing the drain since no apps were listed except some with 1 to 4% of drain....
Any help please...
Ps: am not rooted
App used: better battert stats
