Recently i am observing that my phones most of the battery is used by process called Android system.
Normally this should be screen beacause most of the battery is consumed for backlighting etc.
Is this normal?

I have sometimes the same.
I only used the screen for like 3h but phone is awake like 5 or 6 hours...
And when i loook at stats i see its its waking up. But i cant find any program.
Or what it is....
Odp: Keep awake process battery consumption. ...
Download some app like Ram booster and check out what is it that eats so many energy. It can be an app which is not mentioned separately in the battery usage info, so it is automatically "glued" to the Android OS process.

Use an app that show's battery usage, and try to see what's hogging the battery.
'Smart RAM Booster' is a pretty good app as suggested by fussek. However, I find it useful in killing unnecessary tasks/processes. As far as using it to monitor your battery; I am not sure whether Smart RAM Booster is the best option. You could try 'Battery Monitor Widget' or another app like it.
I would also suggest you get the 'Deep Sleep Battery Saver' app. Usually apps try to periodically update/push data even when you aren't using the phone (which also drain battery). What 'Deep Sleep Battery Saver' does is put your phone into 'deep sleep' so apps can't drain battery while the phone is on standby. You can also set the phone to 'wake up' for a specific interval (i.e every 5 hours) and then go back to 'deep sleep.'
Hope this helps!

No success. ...
I installed battery stats plus and battert monitor widget...
Both shows maximum battery used by android os.
Normally overnight battery use is maximum 1 or 2% but last 3-4 days it is around 20%.Also my phone becomes hot for normal usage also.
In last 3-4 days i installed apps like flipboard, any do, bookmyshow only.
Do youthink any of these causing this problem? But in battery use section they hardly drain 2-3 % of the battery.
I haven't tried "deep sleep battery saver"
I will try it now.

Hmm I don't really see anything out of the ordinary (then again I am no expert at these kinda things). Maybe someone else could give you some input based on your stats?
However, I noticed from your screenshots that you are connected to the Edge (2g) network. Edge is known to drain the battery a lot compared to 3g/4g networks. Do you have any 3g/4g networks in your area?
-Protomartyr
Yes i have 3g network in my area. ... but i was thinking that 3g takes more battery than 2g...
Because whenever i connect to 3g network the phone becomes hot.

Yeah sorry I confused myself. Usually you get better battery life with 2g (but at the cost of speed). What I meant to say is that when your phone switches between 3g and 2g, this switching back and forth can cause quite a bit of battery drain.

I get about 7 hours of battery everyday through medium usage and my battery drains quite a lot when I am revising and listening to music. I have a 1900 battery instead of the stock 1650 and it does improve battery life but is there anything else I can do? I find it a bit stupid that my battery drains so much when I'm just listening to music!
I am running CM9.
Whats the signal strength like in your area? Aside from the screen (put screen brightness down), 3g seems to drain my battery most in weak signal areas, where the signal bars are continuously on 1 or 0. I put my 3g / data off and my phone can easily go hours before any drop in battery percentage, I got 4 days battery life with 3g off using it sparingly or wifi when i could to check my emails. Only other thing i did was calls and texts, but that was just as a test.
But i like to keep data on, and gps, all the time. I often get 4 hours screen time and approx 24 hours battery life with my 2000mAh Samsung battery.
Aside from that, last time i checked cm9 was a battery drain, may have moved on a bit.
the only real way you can save battery "during use" is with some restraint. Ie turn brightness down if screen is on, listen at lower volumes if it's playing music. The more voltage it's using the faster it drains. So less brightness or volume output = less power used.
7 hours is around the average use for battery life savy users around here. Even with the extended battery I'd say your right about on the money for battery use (based on what I assume you do and don't know at this stage). But there is certainly room for improvement .
Now before I go on, you probably won't notice any significant difference to battery life during use from these steps. My only hope is that in-between use it'll save more power, and squeeze out a bit more usage time for you.
First/easiest thing would be go to check if it's sleeping properly. Just don't use it for say an hour, then go to the battery monitor in settings. Check the screen on and awake times, they should be almost idenical. If there are several awake records in between screen on's, then you have a problem.
If you use sounds like unlock sounds etc, go turn them all off.. this was/pretty sure still is an issue in CM9 (causes audio_out1 to continuously wake up the phone from deep sleep and drains the battery like a mofo). Also getting rid of facebook (if it's installed) will help.. it loves waking the phone for no obvious reason.. even with every form of sync, background data, and mobile data in general turned off .
^^ you don't have to do that step but I'm pretty confident you'd have to anyway, so it's just easier to do it straight up. Then you can look for other problems.
Next, install "better battery stats". If you like to support developers, you can quickly buy it off the market. Otherwise it's free here if you search for the official thread.
Reboot your phone, then leave you phone for an hour or two, then check out whats happening in better battery stats. I'm not going to pretend I unerstand what half of the stuff it bangs on about is, but I digress. Select "since charged" and then check each different tabs of data (partial wakelocks, kernel wakelocks etc). You are really just looking for anything that stands out as a red bar basically. small amounts aren't a real worry/bound to happen. If it's bigger than say 1cm long, it's probably an issue. Then it's up to you to find out what the app/process is doing the damage . So either google or the better battery stats thread will be your friend at that stage. It was obvious what is was for me cause it said facebook but you might have a different experience.
Hope that helps. But the only way that's going to make a real dent would be trying to use it less.. lol.
Oh and if possible, turning on airplane mode would save a bit of battery in use. And of course the obvious ones like turn of wifi, gps, bluetooth, data, auto sync, soft key backlight and anything else you can turn off
Just do it what i say .. Download the full version of app. called juice defender from play store..install it and then see the magic by yourself ..i have been using the same ..it almost double up the battery backup through its advance settings.

Been noticing that my gs3 uses a lot of standby power. Some times up to 30-40% how can I prevent this? I am rooted and I run advance task manager

is your phone on standby a lot? the meter is the % of your used-up battery that has been used by that process. i.e. if your phone sits on standby for "30%" and the battery goes down by 10%, 30% of that battery decrease (3%) is from standby.
gentlyr from
based on how you use and how often you use the phone, it may be normal.
for example, i'm at 30% on standby but my phone has been on for 5.5 hours and i have 80% charge. most of my usage today was checking emails and reddit but very sparingly.
Are you in a plce where you have weak signal? When this happens, your radio/baseband struggles to find a stable connection or signal, thus sucking more juice out of your bettery and causing your phone to be on standby mode a lot more.
Flash my ROM - here, prob fixed!

This. With weak connection your phone will be using more battery to find a signal. Check your status to see what % of the time you are without signal.
I was down to 18% after 16 hours with 34% use on standby. I use advance task manager. I belive its custom rom time. I want jellybean. So I must wait.

Has anyone noticed significant battery drain whilst the screen is off, my phone loses around 1-3 % every hour even when there are no programs running. I have monitored the running apps and uninstalled many that were running in the background. Does this mean that the 5th core is not activating or am I doing something wrong, google now, wifi, bluetooth, 3g, etc are all turned off, If anyone experiences similar issues or knows a solution please post, other than that the battery life on this device is actually pretty good despite all the people stating how horrible and unsatisfactory it may be.
I believe someone mentioned that the WiFi is the cause of the drain while the phone is on, is your WiFi on while it's sleeping?

Google Now may cause battery drain while on standby, I think. You might want to install Better Battery Stats so you'll know what's eating up your battery while the phone is in sleep mode.
My WiFi, Bluetooth and 3g are all turned off and Google now has been disabled, don't know what is causing the drain but the people over at the original one X forum are sating that standby drain is higher as of the jb update which I find odd seeing that the battery life is better screen on.
Turn off auto sync & just enable it when you need to, or use an app that will enable it for you after a certain time period.

Nah I can go a day and half on stand by with little use. I have 30+ apps installed and mods to firmware plus nik3r's custom elite kernel.
I'd say its one of your obscure apps you still have I stalled. Do a factory reset on your phone and install each app one at a time each hr monitoring the drain till you find the culprit.
Install nik3r's kernel.

1) go to Facebook app, disable chat, disable location... disable auto updates/notifications too if you can. This crap (especially the latest version) can take 20% of your battery life easily.
2) go to Google Maps settings, disable all the tracking/reporting options out there (up to 15% battery life without ever even starting the map app)
3) install EliteKernel and use power saving if you need that extra standby juice (it actually saves power in my flavor compared to the stock version)
There - fixed.
Wifi is not the issue, I get better life on 100% wifi than on data connection. It's the apps that actually use tha data.
Thanks guys much better now!
turn off this, do not use that.....
if is this the solution what is this? a phone or what?
only hope a room that end with this battery drain, is not normal that my wife S3, the same battery (2100mA) like hox+ has more hours, and not only 1 or 2, 6 hours more battery life, both without use.... in the same place, we did it as a test and..... that´s the Q, why? we have the same apps installed, and we have the same on, wifi, data, gps, blutooth..... the same conditions
In 2 hours, I have lost 29% battery life. I'm pretty sure this can't be normal, especially with 1+hours of Deep Sleep.

Thanks for any info

If you were to post this over at the BBS thread, they would tell you a few things right off the bat:
1. the facebook app is a battery killer. I'd start by freezing it (if you need facebook functionality there are more battery friendly apps for it)
2. Looks like you are doing a lot of syncing. turn it all off.
3. Enable root features in bbs since you're rooted (lets you get more info that may become relevant).
4. You need more idle time. plug in and unplug your phone to create an unplugged reference, then leave it be for a few hours.
The AudioOut_2 wakelock is an interesting one, especially since it's high on your list. In my case it showed up when I tried poweramp and it seemed to be related to the auto-start-when-headphones-plugged-in option, so if you use poweramp check that option. Others seem to get it from viber. If you have that, remove or freeze it.
So, give the above a try, and check a new dump. This will probably give you more stuff to look into. If you find a problematic app you can then determine whether it can be fixed by changing its settings, greenified, disabling its autostarts, or if you just need to avoid it.

From what I see you have had no, or only one bar of signal? If so, you may want to use Airplane Mode. You can use Airplane mode and still use Wi-Fi.
Have you been around Wi-Fi? If you aren't around Wi-Fi, turn it off.
NFC. Is it on? Do you use it? If not.. Turn off.
If your battery level shows inconsistency, you might want to calibrate your battery.
I hope i helped, im not quite sure why you loose 11% every hour, while mostly in deep sleep. Go to performance control and use some tweaks for your kernel.

The low signal shouldn't have any affect on the battery of the G, when I was on aosp I used houcha's kernel an I got great battery life around 23 hours with 5 hours of screen on and was at 22%, with set CPU profiles engaged and no kernel tweaks from any app. And I live in an area that primarily has 0-2 bars of service at home and full lte when I work I leave everything on, all radios and data sync. Now that being said for some reason the development is moving towards synergies kernel, and it doesn't have nearly the battery life that houcha's gets

The AudioOut_2 wakelock can be caused by corrupted Mp3 files on your SD card. It was wreaking havoc in our SGS4G community and the fix for us was always to use MP3val to scan and fix those files. It cleared the AudioOut_2 wakelock right up. I know these are totally different phones but hey its worth a shot. http://mp3val.sourceforge.net

Low signal does in fact drain your battery. When you have zero to one or two bars, your phone is searching for signal, It causes the phone to increase power to the antenna, to get signal.

I understand the premise that low signal causes mor power to be drained, my point was that it doesn't cause 29% on this phone that's not even close to possible

I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??
