android os service killing battery - Galaxy Note GT-N7000 General

i bought my note a few days ago and i cant get it to last more than 1 day with normal usage. today i noticed that my android os service is more than 50% percent of time ON, withing 11 hours, more than 6 hours of usage from android os.
what could couse this issue?

I've just started seeing the same issue this week. I got my Note in December and has been just a bit better than my previous S2 until now. Seen Android OS number in the 80-90% range and phone turns off after 16-17 hours. No new Apps or setup changes lately. Was doing 1,5 day with similar use before.

From Diane Hackborns G+ thread about the impact of wiping the battery stats file:
Android OS is power usage of the core system, below the Android framework. This is the kernel (and its drivers) and many of the low-level non-Dalvik processes like init, ueventd, etc. (Prior to ICS the only thing that could impact this was CPU usage of those processes; as of ICS this is also any wake time that is not accounted for by Android framework wake locks.)
So, this is probably outside of what I can really address, since the part of Android I work on is system_server and the frameworks (Android System would typically be things I know about more). This is also where manufacturer-specific issues can appear, if they have their own native daemons (they very often do) with issues, or driver issues, etc.

The original thread is here.

I haven't been following things too closely, but a number of people report better battery lives after updating the firmware, there are threads in this forum specifically mentioning a drop in the 'Android OS' usage. I myself find this to be true, after an update my battery commonly lasts 2-3 days with moderate usage and 'Display' takes proportionately more battery, as you would expect with a 5.3 incher.
Try plugging your Note into Kies and see what firmware you are running then update if possible.

i think i know where the bug comes from! with wifi on, only 3g my battery lasted almost 2 days with android os 55 minutes
today i turned on wifi and guess what......android os 7hours and battery dead in 11 hours, even with less calls than the days before!
it has problems with wifi!

D-link 655 maybe? Well known battery eater when on wi-fi if you have that router.

tp-link 740nd

Yea I usually have wifi off, it drains!

Have you tried installing Better Battery Stats to see what is draining the battery?
The "Kernel Wakelocks" page might give you some clues as to what is causing the high Android OS drain

Even I was expierencing the high AOS usage in the stats from the previous ROM update...the culprit was found to be the SNS accounts which were not syncing coz of server problems from samsung’s end but the phone was constantly trying to sync,resulting in the high OS usage.Removed the account and now things are back to normal.

What i found was, that if the phone is in "Airplane Mode", Android OS give pretty normal usage. As soon as i turn the cell on (Normal mode), it start to give huge percentage usage ...

kinda same problem here

Same problem here too.

Me too... Android OS is about uses about 40% of my battery as well. But my battery life is good. I usually last about 2 to 3 days with between charges.

No way mine last for 2-3 days. More like 1 and something.
What firmware are you using? I'm still at the official kk5 and i'm wondering about going to LA4. But if it is the same with LA4, i would wait for ICS.

Hello note users.from my previous experiences on sgs2 its not Android os that's the problem.its the MODEM .try flashing a different modem. ( I get my note on Tuesday I hope I've made the right choice by choosing note over Gnex )

Hrmm, that's the case for me, could you ellaborate? Is there any configs i could try, router or phone?
I'm accepting that I need to charge my phone as soon as I get to a charger, but it would be nice not having to do so.
Juicedefender helps alot, but also it introduces some small lags to the system as well, a good enough trade off for now, but if it's solveable then I'd rather try that

I'm on KK1... I have been too busy to play with the note so I have only used it as a phone and checking email and couple websites but that's it. Right now.. I'm on 2 days and 1 hour with 62% battery left with only 1 hr and 20 mins with display on. My android os is 38% with about 1 hr and 10 mins usage. My display is only at 20%. At this rate, I could maybe last four days but I'm not using the screen much.
But I'm happy with battery life... I probably average about 2 hours of screen on per day and that should get me at least 2 days.

I'm having almost the same number as you, but i'm on the 15th hour of usage and onlu 46% battery left. To be honest, i haven't expected some huge battery usage, but hearing you guys i'm starting to think that i have problem. ..

Battery life after initial charges- your opinions

As we all know, the Galaxy S uses a Li-Po battery.
Having previous expirience with those batteries (R/C Helicopters), i know that they require 5-10 cycles of full drain-full charge to reach full capacity and start their normal life cycle.
Not too long ago, there was a thread complaining about battery life here, but i think it was due to people checking usage time on the first or second charge only.
In this thread, i'd like to hear your opinions about battery life, but please-
Only those who passed 5 FULL drain-charge cycles, reply. We need some objective information about it.
Personally-
I'm after my 4th charge, and already seeing HUGE improvement. When i recieved it i barely managed to go through a single day, and now i'm almost 2 days since i last charged it, played some games, browsed a little, made a few calls, and i'm still over 65%.
Waiting to do 2-3 more charges and reach optimal state to see what it's worth.
Mine is a Li-Ion and lasts about a day with almost constant use.

You are correct in that initially we were told the battery type would have been a Li-Pol.
However, since the phone's release it has now come to light that the battery is in fact a Li-Ion.
I made a post that mentions this here if you wish to have a read.
I’ve had my phone approx 2 weeks, so I’m on my 5 or 6th battery recharge. My phone has been on for 1 day 20hrs now. I’ve talked on the phone for about two hours and surfed for about ¾ of an hour. Wifi has been on all the time – Bluetooth about 3hrs. Current battery level is 70% - I must say after all the gloom and doom re the latest smartphones I’m more than happy with the battery life so far and does seem to be getting better all the time.
Wow this is too nice to read, I was starting to worry about my battery being wonky

In contrast I have had my phone since Thursday... I've charged it 4 times in 48 hours so far. I am using it a lot and am hoping I get thee performance rise soon.
Crabby
I'm pretty sure it will.
When i got my phone i charged it to full, and before the day ended i needed to chrage it again.
And now:
Last charge was thursday morning (GMT+2), and now, after 2 and a half days, i still have 40%.
I could probably go on for another full day.
My first few charges barely made it through the working day, but now the phone still has plenty of charge after 24hours. Although right now is an exception, as the lady is playing Abduction on it and will probably keep at it until the battery dies
She really should get her own Galaxy S. Although we're waiting on some GPS improvements before replacing her phone, she cant afford to get lost.

Correct.... She's far too busy keeping me in check, looking after our Granddaughter and the Farm.
I got my replacement SGS today (had to send the original one back as Carphone Warehouse messed up the order so had to send everything back just to get a new SIM) and been hammering it for 14 hours, literally 80% of that running games, using WiFi, bluetooth and GPS and I only got it down to 25% and hadn't even charged it to 100% before I couldn't wait any longer. If the battery does get better after the initial charge, I will have no problem with this phone.
Further to my earlier post...
Charged the phone to full before bed last night... All of the power widget functions of two exchange email accounts and hotmail updating every hour.
So with no other use for 8 hours the battery was at 91% when I woke up. Battery status confirmed that 57% had gone on standby and 29 % on idle
So... Presuming this bsttery use is constant when idle... My phone will be down to 70 % by 24 hours with no use?
Crabby
It varies greatly according to reception.
Good network coverage= less work for the transceiver inside the device=less power drain.
It's not really constant.
Turning off 3G other than when you need it helps as well.

Is this something you do as routine? I don't know if I have the patience to do that.
And my signal was 5 bar edge signal for my 'test'.
Since this morning, I watched 90 mins of video, surfed for 10 mins and made a 5 minutes voice call on the train... By the time I got to work, the battery was at 53%.
I don't feel my phone will last my journey home at 6 tonight, so I have had to put it on charge again.
But still... on 3 days old...

why is battery drain so different

hi
this is not question, just more a thought
now i have read on several post on different forum, about the battery drain on the galaxy s 2.
and my big "concern" is why is there sooooo big different on the battery drain. some people can last for 2-3 days and some only 5-8-10 hours. from what they are telling they are using the phone almost equally..
for an example this first post here, he still have 50 % left, although he saw video,playing , surfing and call http://forum.xda-developers.com/showthread.php?t=1055164
mine last for about 10-12 hour with moderate use.. and i have killed all unused apps/task/services, wifi ,only 3g, low brightness, wipe batt state.. and installed villainrom
it sounds to me that some people get a really good phone/battery and some not.
Everyone's idea of light, moderate and heavy use varies. It really only comes down to a few major things. How long the screen is on, how often the device is awake, and how intensively the device was operating while awake.
If people know what to do (search the bloody forums for a start)they can achieve good battery life, too many fools are too quick to come on here and complain about poor battery life without even searching the forum, also anyone who gets 2-3 days clearly isn't using the phone that much, i usually get a full day out of medium/heavy usage and you cant complain about that, this is a smartphone and if people are that obsessed with battery life i suggest they use an old Nokia

Very true. I can easily get 2-3 days if I just used it for calls and text.
Heck, I can get it to last 1-2 weeks. Just put it in flight mode and don't touch it except every couple of days to check %.
Why people don't just buy spare batteries is beyond me. I bought 3 spares + a wall charger off eBay for around $10. When I'm low I just pop the used one in the charger and replace with a full one. From 0% to 100% in 30 seconds. I even leave one in the car in case. Did the same thing with the S1.
BTW, to the OP why leave it on 3G? I'm assuming you switched off H. For me I use the 2g-3g widget and select GSM only. When I need 3g/H for data I turn it on.

My 2 cents
I will tell you this. For what its worth.
I've had 4 friends get the GS2. 2 of them are white, 2 are black (the phones, not them.)
In all four cases with the stock ROM They came and complained to me how they love the phone but the battery dies before they can get home.
All four cases I've done this update for them via ODIN
- ROM Update: XWKI4 (UK XEU, android 2.3.4 to support google video chat)
- Kernel: XWKJ3 (stock)
- Modem update: XXKG5
Each and everyone has told me they're getting literally exponentially better battery life, snappier response and stable usage.
Take it for what its worth. But i recommend your combo.
I think usage pattern is definitely important but i've experienced idle drain and gone through months of struggling with this. not all roms/kernels have the idle drain issue. The above combo should work well for you. Good luck

Well there are differences in software and usage, but thats it. use a clean up to date rom, good kernel and do not install crappy apps like facebook which drain the battery. Using a modem which suits your provider does make quiete a noticeable difference, especially with hspa activated, idle aswell as using the data connection. Battery life of 12 hours or less is clearly a use or apprelated problem.

Battery Life Worry/Question

My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!
Same here. On all my other Android phones Screen is the top user.
U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.
I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

I tried this and it worked. However, one instance is not proof I guess haha. I will experiment more tomorrow (namely, not rebooting after charging) and let you know what I find. I wonder what specifically about charging may cause wakelocks?
Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.
It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.
Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.
Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.
So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!
Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?

2 years later?

I think this will be a good general discussion:
Whats the battery performance like for you guys on a 2 year old phone, i know after a while the battery begins to degrade which is why im trying to see if this is the case for everyone :laugh:
Also what rom, kernel, tweaks are you using to get your current battery
1.5 years ago I easily get 6-7 hours screen on with power saving mode, for now i only get 4-5 hours with the same usage with Hurricane rom.
this phone is not two years old......
Yeah this phone is not 2 years old yet.. but aside, I love the Note 2 and don't plan on upgrading. I have 6 batteries for it, plus a external charger, so I never have to plug my phone in again. As far as UI goes, yes, it's missing some features, especially on 4.1.2 (luckily I never did the update ), but its multitasking features are kick-ass. At least for beginners. I had to tweak things to my liking, thanks to Xposed, such as default expanded notifications, Multiwindow for all apps, and such, but now that I have so much time into tweaking this phone I have no reason to upgrade.
I hardly noticed any difference between the time I purchased and now. My phone is 18 months old now.
Then again it could b me using 2 batteries and rotating the battery between uses so it doesn't degrade that fast.
But then again I'm not on stock rom. I was using miui in the past. Then regret upgrading to 4.3 which I found it too big of a hassle to downgrade to use miui again (4.1) and used hurricane rom with note3 mod installed. I tried ditto kitkat beta and rc1 but always reverted back to hurricane after a day of usage.

I was stock rom and after numerous useless updates from samsung my battery wont last even 12 hours. I moved to xperized rom and even then battery backup was less.

Hmm yeah thats what i get too here and there depends on if i play games or not which i rarely do! Im trying out Omega rom v27 4.4 atm and testing the battery for a couple of days :fingers-crossed:
really guys only 6-7 hours? I go at least 10-12 hours, yeah of course it depends how much you use it for example when I use 3G and Wifi Hotspot simultaneously the battery drains like 1 second for 1%. I recommend you guys to install WakeLock Detector app. This app will tell you which app drain your battery, and guys, remove the facebook app as soon as possible it was on the top of the list.

After a long time i cn see this result.Thanks to geekynoob.
I am on Stock 4.3 and last battery report attached
Sent from my GT-N7100 using xda app-developers app
My battery life is steadily declining. Still getting by the day, but not easily like it previously was. Hopefully it'll last until the Note 4 hits.
Is there an app out there that can accurate measure the battery of your phone?
There are tons of battery app , there is one that comes with CleanMaster app hope that should be good as cleanmaster is good app
I get 2 hours and 30 min with screen on and 5 hours with the phone off the charger and on 3g and 2 hours with screen on and 4 hours on 4g with screen on with stock 4.3 and custom roms and i get 7 hours with the on wifi and 2 hours 30 min with the screen on that is with good signal and on Telstra.

I've only had the Phone since 16th of January 2013 and that is with two battery as well
After 1 year 2 months of usage, my note 2 lives around 7 hours screen on for wifi and 5 hours screen on for 3G

Redmi note 7 HIGH battery drain

Hello,
my uncle just bought me a brand new genuine Redmi note 7, I opened the box and turned the phone on.. I noticed that the battery was at 66%, I set up the phone which took a minute or less and that's when I was about to connect it to my wifi BUT then I notice that the battery is 63% ALREADY.. Now knowing that the phone has a 4000mah battery I was beyond shocked too see a 3% drain with low brightness and just 1 minute of light use literally no SIM or internet was being used.. so I turned it off and charged it to the max.. After that I turned the phone back on to update miui.. I connected the phone to my wifi and started updating to the last version.. available from the updater.. it took less than 10 minutes.. and guess what I see? 100% to 89% in less than 10 minutes that's crazy.. I bought this phone because of this guy w ww. youtube. com/watch?v=3gaWbx2x06s as we can see in the video he gets almost 8 hours of SOT with full brightness wifi and youtube FHD... right now I'm doing the same experiment and adding battery saver setting and my battery is draining fast I'd be surprised if I got 4 hours of sot... I don't understand... what's wrong? The phone is new and genuine since I verified the imei.. Thank you.

I believe every phone does the same thing like that when you configure them for the very first time. Full brightness, wifi scanning, mobile data ON, GPS ON, sync ON for a few minutes can consume lots of battery.
My advice is to fully set up your phone with all the apps you want and turn off any features you don't use. Use and recharge your phone normally for a few days. Check for battery consumption stats using native graphs or popular battery tracking apps. Analyze graphs and stats and draw the conclusions yourself. (Don't trust everything people say on YouTube, trust your own experience.)
In the worst scenario, you can always return your phone within 7 days of purchase. I hope you don't have to! :fingers-crossed:
My brand new redmi note 7 is a little fast draining right now too which is a little disappointing but my redmi note 5 was also the same fast draining when I first purchased it and it improved so I really hope this redmi note 7 does the same and improves.
I have both phones side by side right now so I can kind of compare usage

Yeah even my mediatek redmi note 4 didn't drain like this.. now when it gets to 15% it just discharges completely.
One thing I will mention is facial recognition. It could possibly drain the battery faster so I have just turned it off for testing purposes. I need to see what difference it makes but that's really the only difference between my two redmi phones 5 & 7.
Any new phone battery will take a few charge/drain cycles until it is calibrated correctly.
Use it for a while and see if the battery settles down.
Also different countries have different mobile systems. This will also affect battery life as the phone needs to continually scan for a signal....

30% brightness.. only wifi.

I know the post is old but I have the same problem ... I think we are so many to have it !!
I have a Note 7 for more than a month and it never went well ... I managed to do only 3 days but almost without using it, there are people who also do 4 or 5 days of use ...
Anyway if I use it it makes me amalapena 1 day ...
When I use the phone I see that it consumes my battery quickly even if I just navigate the phone menu.
I've already done at least 4 reset but it didn't help
I do not know what to do..
Did you solve the problem?
miui 11 could help?
Thanks
Imposible to do 4-5 days with this phone or any phone when u use it. Why do u have smartphone when u dont use it and u care about battery?
What version MIUI are you all using?
I'm still on 10.3.5 and battery life is great.
I average 9.5 hours SOT ( 2 days worth) with normal use and have got as high as just under 11 hours SOT a few times.
If you're not on 10.3.5, can you roll back?
I've heard of battery life issues after updating to the newer versions which is why I'm staying on this one until they work out the kinks
My battery life has improved since my earlier post just as I expected it to The note 5 does last a little longer when I put them side by side but they are both great phones and the batteries last for ages with normal daily use!
I barely use 50% with gaming (currently clash royale) social medias, spotify for around 2 hours and some other stuff plus I'm working 5 days a week so I don't get to see my phone for most of the day anyway

might be a dumb question but, how/when do you charge your phone ? do you wait for the battery to reach 0-10% and charge it back to 100%? or you do the 20% to 80% charge "cycle" ?
I try to charge my phones every night now when I go to bed, The note 5 & 7 are around 50% most days from useage and I charge them from around 8/9pm until I wake for work at 5am (Living the dream)

and what SOT do you get with the 50% usage ?
I am not sure, Because it almost never drops below 50% in a days usage I have stopped looking and worrying about battery life It just lasts and lasts for me.
However I will try and take notice over the next few days and report back if there is anything to report...
