Extreme battery drain by android system - Samsung Galaxy S7 Edge Questions and Answers

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

[Q] bad battery life on my hero

Hey guys, i have a problem concerning the battery life of my HTC Hero with FroydVillain 1.7.3 (Android v2.2.1)
In the last couple of days my battery goes down by 10-12% per hour without even touching the phone. I tried factory reset, wiped sd card and reflashed, flashed CM7 but still the battery issue didn't go away.
I charge it 100% before i go to bed at 11.30 and when i wake up at 7 the phone is completely powered off..
The thing that consumes my battery is the process "Android OS". I read about it on the internet, but all threads were SGS2..
The strange thing is that it's CPU usage time according to the battery stats is 1h 21m after 3 hours of sleep.. Is this normal??
I have everything turned off - wifi, gps, mobile data, auto sync, background sync and still the drain continues.
Has anyone had this kind of issues and possibly a solution?
Or should i buy a new battery?

I have also been experiencing battery issues with Froyd lately, but not to the same degree as you are. My solution was to wipe and install another 2.2.1 based ROM. This new ROM is acting normally in terms of battery life.
With Froyd, my battery was acting "weird" in terms of overall battery life. Once I got about 3 good discharge / charge cycles in a row things seemed to improve.
Another thing to consider is did you recently install any new apps? Some apps don't play nice and cause the phone to not enter sleep state OR cause excess CPU usage.
Some people might say "wipe battery stats" but some Google Engineer / Developer has recently dispelled that myth... https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
Good luck!
It's not from any app. Last night i wiped my sd card, wiped everything from recovery and flashed Froyd. I used it all day without installing anything besided battery graph to monitor my battery usage. it's something from the OS itself i guess..
The funny thing is that it seems that in the past two hours the drain has disappeared and now the battery is reducing by ~1% per hour and i haven't done anything during that time, except 2 calls under a minute each and 1 sms.
How old is ur battery? Did you consider that it might be physically related? Not because of the processes or so?
One more thing I noticed - if I charge by ac outlet, it charges faster, and lasts longer, if I charge by computer usb port, it charges really slowly and battery drains way faster... I don't know about battery life, maybe from ac outlet it dies faster, but 2 years of using it and still 1.5 day of normal use...
Thanks for the replies guys! I found the problem, it was my radio.
I flashed the latest radio and now my hero's battery life is better than before!

Looks like you have a battery problem. OS does not really kill batteries, you can see more or less the same performance if there are no background apps eating your power.
Check these batteries for your Hero. These are top quality and many users vouch for them.

@saj222 i'm now running the same radio as the one in your signature. before that i was with 09.05 or sth like that..
@porcupineli my hero is second hand with about a year of usage before me. i have it for about 2 months now. Since the phone costed me $90 i don't think i can pay $70 for a battery.. I was thinking of buying this one

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] Battery issue after reroot

I had some issues after rooting and installing liquid smooth so I unrooted and installed stock firmware. 4.4.2 vodafone uk.
I've rooted again (cf) and deleted a fair amount of bloatware.
My issue is just battery related.
Normal usage just seems to hammer my battery. (About 10% gone in 20 mins phone and internet usage)
There are no background apps that I can find.
Screen is using most battery (40% which is expected) followed by OS etc.
I can charge my phone during day (I spend a lot of time in car) but that's not quite the point. I shouldn't have to!
Anyone got an idea of what might be causing drain???
I've ordered a new battery to see if it makes a difference. Could the issues I've had recently somehow shorted my battery a bit?
NB. It doesn't seem to drain much when locked. Only when in use.
Any trouble shooting appreciated!!

Maybe it's the battery.. how old is your phone? Or if it something else, you can download many apps which creating battery stats, like this one here: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
You can also download anotherone. But with this kind of programs you can look what drains your battery so fast.
I've got betterbattery and gsam.
Not sure how to use them though.
Bbs:
under process system_server says 63%.
Gsam says 45% (which seems ironic)
Under network vending google ply store says 96%
Gsam:
58.9% is consumed by app usage (389 by screen)
Biggest app sucker is android system @20%.
These stats help or do I need to give more info/screenshots??

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.

Note 4 Fast Battery Drain

Hi,
Not sure if this is in the right section so admin please feel free to move.
Ive googled my problem and had a bit of a read but dont really get any solutions.
Ive noticed a serious battery drain since upgrading to 6.0.1 - maybe it happened on the previous version however ive just seemed to have noticed it more since i did the update.
My battery doesnt last very long. It will show 100% in the morning. If i dont use it, it can go down to about 80% within an hour or so. If i do use it then im using apps like gmail, whatsapp / sms, short phone calls, some other apps but im not on them for very long. I normally close all apps that are running in the background.
This morning it was 100%, ive used it as described above and its on 57% and its not even dinner time yet...
Ive checked the battery usage and top of the list is " Cell standby" with 48% usage showing power used is 1530mah - which is alot. The next is "my data manager" (an app to manage data usage) showing power used is 485mah (alot less!). Ive attached a screen shot.
Ive also noticed that once the battery gets to around 30% it drains even faster. I find myself using power saving mode when it gets to about 20%. It still seems to drain at a similar rate. Maybe slightly slower.
Any ideas on what i can do to recover battery time without buying a new battery. There seems to be a few topics online relating to battery drain when updating to the latest android version.
Thanks

Factory reset might help a lot.

I had same battery drain issues when i updated from lollipop to Marshmallow but after doing factory reset everything is better then lollipop and doze feature in 6.0.1 works very well. I leave my phone at night about 9 hours and not drain even 2% battery and i got 5 hours scrern on time .
try factory reset+wipe cache from recovery and use atleast 3 days to doze feature work properly.if you have same drain issue then it's a bad battery.this is the only solution so far.
Battery pull?
