huge battery drain from "Android System" - Samsung Galaxy Note 8 Questions and Answers

Hello,
Since the last 48 hours I have huge battery drain from "Android System".
Something like three times usual battery drain.
I don't remember what I could have done that would explain that sudden change in battery drain.
Anyone have an idea?

Have you rebooted?
Also do a forum search as there are literally hundreds of threads about this .......

Battery drain issue EVEN when the screen is off. Help??

My relative complained that he suffers from a steady battery drain somewhere around ~2% per hour even when he turned off the screen. If anyone is wondering, no it hasn't been flashed nor rooted before. Didn't get the chance to Help??

Its really hard to tell exact solution without knowing cause. First try to identify cause, use betterbatterystats app to know which wakelocks are causing this, you will surely find problem using BBS and eventually solution !
A very common scenario is running app in a background which is either using location sharing using GPS or data sharing using internet connection..... might be syncing opetation as well........
There are lots of threads on battery use & battery drain. Look at a few and see what may be similar to your issue.
We almost need a separate forum for "Help: Battery is draining!" threads, no? The trouble is, they mostly have the same answers, so many of us get bored answering them.....
Okay will try. Thanks.

Not getting good battery life on my ONE

Hi, I have had this phone for almost a week now and have noticed that battery life for me is shocking. I JUSSST about manage to get through a day and some days have to charge the phone a little half way through the day to make it last the extra mile. After the first few days of heavy usage I went back to my regular usage pattern but still the battery hasnt been good. I have posted many screenshots and posts in the 'battery life' & 'battery stats thread' in the ONE General section so check em out. I downloaded GSam battery monitor and found out that my phone has many wakelocks from 'wakelock mediaserver'...at one point I had almost 900 wakelocks from it :/ I tried everything to fix this but couldnt. Plus the phone in general would lose 1% battery every 50 seconds to a minute. I had to resort to a factory reset in the hope that it would fix the issue but that wasnt the case. At first the mediaserver wakelock was nowhere in sight and battery drain was ok compared to before, but then again its back to draining insanely fast and the mediaserver wakelocks are back. Anyone else have this problem? Or anyone else finding that their battery is draining quick?! Because if this persists then im gonna take it back to p4u later in the month and get a new one. Just want to know if this is only happening to me and if anyone has any solutions. Thanks

I'll be honest I didn't have hope for the one and it's battery. I got this one a week ago. It's on it's 5th charge. That's good! Are you a heavy user?

Well I think I'm a medium to heavy user. But most other people, especially reviewers who probably used the phone heavily are easily getting over a day of use.

Yeah suprsingly I am almost. It's weird. I think blinkfeed helps in a weird way. Instead of checking your facebook. Twitter.news apps etc it's all there to look at. Might save juice I don't know.if your worried return it though dude

If you loose power so quickly on new phone you have two options - battery not good or you have too many things going on!!! I will bet it is the second option! Under too many consider all processes you have running on the device.... less job for processor(S), more battery live! All phones come with a lot of crap installed form the vendor(map, wheather, location services, etc...) I will recommend to kill(dissable/enable) all processes you do not need!!! Make a test, but get all important staff out of the phone, so you may need to factory reset if you kill something important. Do not worry, with fact. reset will be like new..... and all the crap already started So good luck
Found this in another device forum, but it could (possibly) help you with your wakelock problem.

I've never had the mediaserver wakelock (nor do I have the One yet), so don't know how well this will work. I suppose it's worth a try. If not, you might try Googling the mediaserver wakelock problem to try some other solutions. Seems to be a relatively common problem.
I'm guessing you're a heavy user!
What apps to you have installed? how many apps to you have?
My phone lasted 1 day and 9hrs on one charge with moderate internet use, txt messaging, phone calls - and that was without power saving mode enabled.

LTE actually uses almost as little battery as being connected to wifi...

Recent Android OS Battery Drain?

My android OS is about 32% today and about the same with my three other note 3 friends, rooted and non rooted. Anyone know what is causing it or if you have the same issue?
I'm just stock rooted.
Same issue here. It's very odd.

I have a Zerolemon 10,000mah battery, no issue here.
I'm seeing the drain here too but it's not hurting me too badly. Android OS is topping everything at 32% and has been since yesterday.
Seeing NipCollectorWakeLock as the number one partial wakelock on my system by a country mile.

you fixed it yet?
I tried the updated Google Play Services APK which is supposed to fix battery drain but it's still the top on my list. Can't say it's hurting me much though. 74% battery left after 12 hours (1 hour screen on time).

Its been uncheck since day one.
There's no fix yet. For me it's network /signal related. Outside at work the process is awake for about 4 hour /12 while at home on wifi most of the time is under 1 hour. Still on top of the list though.

Sorry, made a HUGE difference for me. I would continue to look at "location" stuff, notorious batt eaters.
Anyone know how to fix this?

Problem with my htc one battery life, Please help

Hello..
I have a problem with my htc one, every time when i charge it the battery goes down to 95%-90% in a minute and i'm not running anything, it's kinda weird only the android system is taking 98-100% of battery usage. the battery drains bad
i don't know what to do?
i want to know what does other htc one users see in the battery usage
This has been discussed to death, please search.
Basically, you need to charge for maybe another half an hour after it reaches 100% charged.

I know it will drain but not like that i had it for 6 months now, and the system is taking to much of the battery, other phones OS doesn't take that much.
see the screenshot.
Everyone has a screenshot that looks like yours. It's normal. Just because it's high doesn't mean it's draining too fast. I don't even bother looking at mine. Much better readings from other apps on what causes battery drain. Looking at your screenshot isn't one of them, as you can already notice.

Battery Calibration issue

Could someone kindly point me to the area of know-how for an issue im having with my battery. After flashing many roms and restoring many backups, my phone is losing battery faster than ever without any services running. I have used a battery calibration app to assist in my issue but to no avail. It will drain very fast but lose ZERO percents over night and even gain 4 to 5 percent while the screen is off for extended time. THis led me to believe my battery is out of whack and needs some TLC pls help b0ss

Maybe no one has helped you because they don't know the answer. Look at the forums for this device, it's not very active. Most people have moved onto other devices. As far as I know, there is no way to calibrate the battery. Have you tested a different battery?

i thought this was a general request regarding batteries, not the device itself. Mod moved this thread here.. ive tried the apps, i also just deleted the batterystats.bin file and rebooted. Still hangs on 2 %. I did buy an offbrand battery that claimed to be 4200 MA but it wasnt. It was stock size and that battery was chill for the most part for a week then literally bit the dust. Wouldnt stay charged. It even weighed half the weight as my 2 year old original battery. So now im on the 2 year old one with this issue. Would you think it would be the battery itself making this happen? Or is it related to my software?

Oh I didn't know they moved it here, I thought you originally posted here. I'm not sure on S5, but on my old LG, after flashing a few roms the phone would act weird with battery life. I'm not sure about the specifics, but I think getting it back involved draining it to 0%, charging to 100%, then draining back to 0%, and repeating the process about 5 times. But that was a different phone, so I'm not sure. Have you disabled any background apps that may be running? I've disabled all touchwiz stuff I can think of so it won't run.
