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.

Android OS Wakelock killing the battery!

Hey guys,
I've been having an S6 Edge+ for a couple of days already but there seems to be an issue with the ROM. I'm getting a lot of battery drain from the "Android OS" and I'm losing up to 5% - 7% per hour in standby.... I have even re-flashed the entire ROM and factory reset two times... still the same.
I've disabled Google's Location History and Google Now but this did not help...
My previous Galaxy S6 was also running the latest ROM but there were no such problems...
Has anybody else experienced such an issue and do you have any ideas?

Check if any sync is stuck in loop, sometimes this kills battery very easily. If all else fails check with some app like GSam.

Unfortunately GSam does not produce too detailed information without Root access and it only says Android System and lists all the services that are under it...
The interesting part is that after several re-flashes with the same firmware, the wakelock disappeared...
Now I get 76% to 80% deep sleep...
Go figure... Probably some stuck sync as you mentioned...

Android OS Wakelock killing the battery! ...... solved
OK, im not too savvy with settings and systems, just sharing what i have been through. I too had a major battery drain problem on my S6 Edge+ , giving me abt 8-10hrs of use after a full charge. Even during the nights with everything off and power saving enabled i would lose abt 50-60% battery over 8 hours. ..... caused by Android OS ....... it would keep the screen awake for hours even with the screen off .... ( dont know how that worked) ..... tried a factory reset but didnt help. Then rooted the phone and downloaded wakelock detector and installed it as a system app. Installed greenify and doze ..... last night lost 4% over 11hours with wifi and 4g off and power saving enabled which is a drastic improvement. Facing one little problem that images do not get downloaded (automatically or manually) in whatsapp with wifi in use. Will use the cell for a few days and post again abt how the battery is holding up and if there is any other performance issues.

If you want to save battery, try this app:
https://play.google.com/store/apps/details?id=com.kunkunsoft.packagedisabler
It show all RAM usage of each app, you can disable any app in Bloatware (samsung default app) list to save power
This app run WITHOUT ROOT

Note 4 stays awake and drain battery while idle

I am using Note 4 (N910C) bought new 4 months ago but some times device behave weird. Sometimes device stays awake (cpu stays active) while screen is off and the device is not being used. When this state happen in the battery stats it can be seen that the awake line becomes strong and permanent and only solution is to restart the device.
After restart, device behaves normal for about 2 to 3 days and after that same problem persist. During this situation 4% per hour battery is consumed when device is idle.
In battery stats Android System and Android OS consume most of the battery when this problem happens. Otherwise device consume normal battery and I get about 6 hrs of screen on time.
I have tried several solutions like
Cleared cache.
Disabled some pre installed apps which i don't use like svoice etc
Disable sync services
Installed Gsam battery monitor but no-special process found other than android aystem which consume battery in problem state.
But nothing mentioned above really helped. The only known solution is restarting the device which help for like 2 days and problem comes again.
Device is not rooted and I am using original Samsung OS. Lollipop 5.1.1 and Marshmallow 6.0.1 both have same problem the later was updated via OTA. But nothing addressed the problem.
Please guide with the possible soultion?

I have the exact same problem, would be great if somebody can help

I also have the same problem, i'm going to search deeper in the forums if someone solved this months ago
So far it ends up wasting the battery of a generally idle device and stays up long enough for my screen and body to heat up when left unattended.
Have you already fiddled with the screen settings itself? Particularly Settings>Device>Display and Wallpaper > Smart Stay? I turned mine off and it did reduce some of the battery drain issues.
WiFi and mobile data (even just the plain mobile signal) seems to drain the battery too a little quickly.

S4-i337 battery drain via Android OS

Hi there, for the last week or so, with no new apps being downloaded prior to issue, I have noticed a significant battery drain by Android OS (39%) and inside it showed incredible Keep awake time of 16h 50m (though the phone screen is off). For reference, the screen time (25% battery usage) so far is 1h 31m. I have installed and given root access to GSam Battery Monitor (its root companion is activated too). The program indicates that Kernal (Android OS) is taking up my space but I was hoping instead it would be able to give the direct app that is eating up my battery. I have tried restarting it twice and after letting the battery run off completely and fully charging it before turning it back on.... no dice.
S4 - SGH-i337M (jfltecan/jflte)... verified root... Android 4.4.2
SlimROM-4.4.2.build.4-OFFICIAL-3650
Build number: slim_jfltecan-userdebug 4.4.2 KVT49L 3650 test-keys
Kernal: 3.4.82-KT-SGS4-gb0a91ad
Recovery is via TWRP
I know there may be suggestions to turn off GPS, WiFi, etc, etc... but I'd rather not do that due to the fact the phone life was absolutely fine w/ them on... I'd like to fix the root of the problem instead of working around it. I haven't made any changes to phone settings for a month. Reformat is a last resort but want to exhaust options prior to.
Any help appreciated, thanks.

It seems that the only way to have figured it out is by disabling individual apps and see if there is any improvement in battery life and drop in Android OS wake time and battery use.... After checking the 4th app of possibility, it seems like KiK was the culprit. Just going to remove the app as I haven't used it much. Maybe an update for the app occurred causing this to happen. One work around for those who want to keep the app that's causing the issue and minimize the battery drain, you could just go to the app's system settings and do a Force Stop and the program will be off and then turn the app back on whenever you need it and then turn it off again via Force Stop. It's a app issue, not anything you can really do about it except downgrade or uninstall the app.

1. Install one of the available battery monitoring apps. I recommend BetterBatteryStats:
https://forum.xda-developers.com/showthread.php?p=15869868#post15869868
2. Read carefully the instructions/help
3. When you get some knowledge about battery overview and wakelocks -> analyze the results from the app by your own and try to find a cause for your problem or
4. Make proper dump file from the app and post it on the BBS thread asking for help.
