Android system battery drain - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi,
Im getting bad battery life in the past 2 months, I tried to flash the latest stock rom, rooted the phone and deleted bloatware, and im also using greenify.
after doing all of those things im still having trouble with battery drain.
at GSAM battery monitor it says that the app usage is 62% (screen is 31%)
20% goes for Android system, and 13% goes for Kernel (Android OS)
at settings - Android system 25%, 15% android os, compared to 15% screen.
Is there anything left that I can do it order to fix this?

Note 3 | 4.4.2 version|battery drain of 22% overnight.

Hello All,
I'm using note 3 France version. I notice that overnight my phone is getting, yesterday night my phone was charged till 93%and i closed all the running apps & when i see this morning, am left with 71% of juice.
Stock Android + no root.
When i look at the battery graph, it just says "android os" for 100%.
Is it actually hiding any of the background process?
Is this normal?

In my case, the sd card is the culprit. Every thing back to normal when i remove the sd card.

SD card shouldn't be a problem, many people use them without any issues, you may have experienced indexing bug, some program residing partially on a card got shot down, when card was removed, or something of this nature.
As far as OP goes, even battery display itself is weird, never seen anything like that. On mine Android OS, Android System, cell standby, device idle, something from Google and screen will show up at the minimum. In your case it seems every other battery usage had to be very small, way less than 1%, If you press on Android System, you will get more details, but no matter what I would do full factory reset to start with, since neither 22% idle discharge nor battery display is normal. Just make sure you have full backups, since you'll loose all settings and need to reinstall all programs.

Note 3 battery drain problem Solved...
Hi all..
I am using a note 3 LTE N9005. I was facing the battery drain problem with my phone it used to drain at a rate of 10% an hour even when the phone was locked and kept idle. Like some one mentioned above if I kept it aside after full charging in the night it would be around 50% in the morning.
Then i installed wake lock to check what was causing the issue but couldn't find anything unusual.
Later i noticed that my android system and android OS were consuming more than 35 % charge everyday. Even wake lock and other similar apps couldn't find it.
Finally....finally i decided to uninstall few apps one by one and check if anything changes..... and yessss..... i found it.... Facebook app and Facebook messenger were the culprits. ... particularly Facebook app.
Now without them... i am getting a full 6 hours screen time and 24 hours on normal usage. Just try it.... its worth a try.
Please note : My phone : N9005
Android version : 4.4.2 KitKat
Hope this help you.

[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?

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.

Android System and Kernel (Android OS) draining battery.

My battery has been acting weird these days, It has been losing battery when the phone is not being used. I wiped cache from recovery and it was good again, but after 1 day, the drain came back. I used GSAM to see what was draining my battery and I saw that Android System used 22% and Kernel (Android OS) used 10%, it means that both used 30 of my battery, is that normal or what ? I have 6.0.1 Thanks.
Thanks !

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?
