I have read a lot of threads regarding battery life.. But I really don't care having 2 days with 3 or 4 hrs of screen time.
My deep sleep is actually very good 96%-97% in 8 hours... But I want to know what to do to minimize the battery USING the phone while browsing.. Screen brightness I always have it a lowest possible.. Also have it UV a bit, using LiLRom 1.5.1 with entropy 3/5 right now is dropping like 1% in 3-4min... Is there anything else I can do to increase the time for lets say around 6-8min ? I guess 10min/1% will be impossible..
80% of the power usage is due to the screen. That's the price we pay for amoled.
Disabling "Use Wireless Networks" under Location and Security in Settings helps.
That will stop the apps that you are using from unnecessarily polling your location. For example, I've seen Facebook turn on GPS every time I access it even when all I am doing is checking my Wall. Turning off above mentioned option prevents this.

If your browsing the forums, you need to use the black theme in Tapatalk (xda premium). Black is our friend for battery. Could also drop your CPU/GPU clock down 1 step, but the screen will be #1.
There's an entire thread full of suggestions, why start this one?

Yup, guess you are right, but I think it´s possible to get a bit more usage.

Because that thread is focused mainly on battery drain while sleeping and if you read my initial post I already have that sorted out.. here I am asking for USING the phone, not overnight drainage.

Yeah I have read your thread and is a very nice one but the problem on that thread is that it became some sort of competition of which combo rom/kernel have the better battery for a period of days.. And not squezing the most of screen ON but using the phone. I did some test a few months ago, and if only the screen is ON but without touching the phone it will get nice times. But once you start touching the phone is when the power consumption is bumped.
But will be nice to see a guide with some values to mess with freq,mv,etc.. to get a balanced consumption between usage and performance..

Well, that was just an example. I too don't use the FB app anymore. The focus was on disabling the "Use Wireless Networks" option

I am trying to crowd-source what people do to get good battery over here in an xda thread. If you add your settings to that form (after jumping to that post), it may help telling you and others as to what settings help towards and against good battery life.
Hie guys, I just woke today to see my phone was off and when I switched it on the battery was @17%, from the battery stats in settings it shows my phone switched off after 2hours of me sleeping. So what can really make a phone lose 74% battery whilst it's OFF??!!
Help me or you can paste me a link to where similar problems have been discussed.
Thanx.

Download a battery calibration tool off the market and use it, I have had this happen to me before where i would lose over 50% of battery life just by restarting my phone, and it would gradually go back up.
Also check if their are any updates for your rom and os you are running

Probably a pointless exercise since it's been proven you can't "calibrate" the battery in an S2.
I've had something similar happen, I was raping my battery with a torch app then restarted. Before the restart I had about 90%, after it was around 30%.
Could it be a sign of the battery failing? I've not had any real problems otherwise..
Perhaps you have wake locks? Purchase better battery stats or download it using the search button.
A high battery drain is often a limiting factor for a great user experience.
With BetterBatteryStats you can analyse the behavior of your phone, find applications causing the phone to drain battery while it is supposed to be asleep and measure the effect of corrective actions:
- Spot drainers based on detailed information about the root cause
- Use the online Knowledge-Base to find how to reduce or remove the wakelocks
- measure the effect of actions to reduce drain
- detect changes in the awake/sleep profile and quickly find the causes (rogue apps)
I've seen other people post that the OS is using 30%-40% along with the screen using up some power but I'm just curious, is there something wrong with my phone if it says 93% of the battery is being used by the OS and only 3% is being used by cell standby when the screen is off?
Sometimes I forget to charge my phone overnight and I see 25%-35% of the battery gone and the main culprit is always displayed as Android OS using 90%+ of the battery life consumed.
Let me guess..... You're running the official at&t ics release?
Hell no there's no way I'd ever use official builds again after flashing/using custom roms. At this moment I'm using the latest AOKP build along with Siyah Kernel 3.4.3.
Some apps u may use may disguise themselves as android OS. Better Battery Stats could help you determine what's draining it

Alright well I installed the app and let my phone run on it's battery for a couple hours. The app showed that my phone was never in deep sleep. I looked under Partial wakelock/unplugged and it displayed 99.7% was used by *backup* android system. I'm not really sure what that means but regardless my battery life did improve quite substantially after installing the app so thanks!

lol, BetterBatteryStats shouldn't really be improving your battery life, but who am I to judge. Check to see under Settings > Backup & Restore see if the box for "Backup this phone with my Google account" is checked. That could be causing your drain issue.

Right. BBS does nothing on its own; it merely provides information. Seeing better battery life is a result of the random nature of that wakeup. When I had the issue, I don't think I ended up finding a solution. Unchecking Google backup had no effect, but I leave it unchecked nonetheless.
Well I don't know what happened but obviously something must have if I see 30% increase

I've been using my s3 for the past one week and my device shows 99% assoon as i remove my charger! i've tried changing the rom, erased my Battery stats, recalibated my battery using playstore apps. even though it shows 99%. please help! by battery life is worst!
All GS3's are like this only. The battery actually never charges to 100. Its purely cosmetic.
Please tell me you've actually tried searching for this before posting since there are literally dozens of threads and discussions revolving around it.
Physically it's very simple. If a battery is 100% full, it's as full as it can get. This is not true for everything but for most consumer-related stuff. (Airplane turbines, reactors and other industry-machines see it as a maximum value for long-time usage but can go quite a bit above)
If you unplug it, your phone starts draining battery since -surprise,surprise- it needs power. So the battery cannot stay at 100% if a (however tiny) part has been removed.
Phones that remain at 100% after unplugging for some time are lying to you to make them look better. And you don't want a manufacturer lying to you, do you?

Better check of you have rogue apps in the background or your screen brightness, my batterylife is quite good (about 2 days with medium/heavy) use. Running stock firmware.

That's perfectly ok. Relax Been discussed here already...
PS absolutely no need to calibrate the battery
This happens to me as well but don't fret over it.... Calibrations should be done regularly but not overly or it'll stress your battery more than necessary.
You do not calibrate your battery regular the year is 2012 not 1995 .
Battery auto calibrates itself use it ignore it .

I'm amazed how people can get nearly 2 days with medium usage. Do you have any apps installed? How many hours screen do you get?
It seems it's pot luck with battery life..
I've seen a lot of users' postings of battery statistics (screen shots) and they are all considerably better than what I am getting. The biggest difference I see is in the amount of battery drain from "Android System." What I see posted is between 9% and 13%. However, my batt stats show the Android System draining 60% of the battery.
So, what am I doing wrong? I'm still kind of new to Android. Is it the widgets? I've checked running processes verses what apps are draining battery life and nothing is running that drains like the system does.
Further info: I am currently running the 7.18.12 build of Diet ICS, but I was seeing this behavior on stock as well. Some widgets I use: Astrid premium tasks widget, Evernote, doubletwist, slacker, 3D clock/weather, a widgetsoid switcher, and APW Calendar.
Thanks for any help or suggestions.

How much screen on time over how long and what kind of use?
60% is high but there's known bugs in android OS reporting.

How often do your widgets that gather info refresh? Try scaling down on some widgets and see if that helps. If not, try to flash stock with odin and start over. I was having some problems with my phone when I first got it (MTP specifically) and I falshed stock and everything started working fine. Also, if you are using Google Chrome, make sure you have the experimental feature of using the gyroscope for tilt scrolling set to off....it is known to drain battery.
Hope this helps :good:

Maybe I will try flashing stock if I have time today. I reset my battery stats in recovery mode when I took the phone off the charger this morning, so we'll see how today goes.
I looked into the widgets and the only one that refreshes data on a schedule is the clock/weather. I'll try a different one or just not use the weather.
Great tip about Chrome. Didn't know it did that.
Do I actually need to calibrate the battery? I tried the method of letting it die and charge back up a few times and I've tried recharging once it gets down between 70-80 percents life. I'm not sure which method helped, but I did notice an improvement.
Thanks again for the help.

Not sure how to know how long the screen was on. Is there a way to know that? If I had to guess I'd say 4 hours. I use the Smart Stay option as well. I wonder if wiping the stats will give me more valid data.

I have my display off auto-brightness and on a low setting, I probably utilize the task manager 50x a day and clear the ram as well, cpu sleeper is always activated, gps/sync/auto-rotate/wifi/bluetooth is always off unless I need them, and I have power saving mode on most of the time.
With all these settings off and I am a heavy texter/caller/browser/emailer, my battery lasts from 7AM-1AM and I am at 30-40% at the end of the day!

Never mind! Just searched" CPU sleeper" on the Play store and--voila!
On another note, I'm so glad I got a device with a huge support community. Coming from iOS, it's nice to feel part of a collective effort again and get such great advice. I know there are a lot of iOS forums and there is some great work done through those communities, but those seem so trivial compared to what is done through XDA and the level of helpfulness is unparalleled here.

I read somewhere in the forum that these batteries actually like to be constantly charged up and not let die completely. There was no explanation for this but I will research it because I am curious. With my old Captivate, i let it die then fully charge to extend the overall life of the battery.
How is your battery so far?

I've applied all the tricks folks have shared here and have flashed the Diet ICS rom. I am going to take screen shots of my usage data on a daily basis and see how things fair. I'll post my results here. Here is one from last night before really getting into all the tricks and the new rom. So, maybe this is my "before" shot in this documentary of a noob's journey to better battery life.

Have you tried using the CPU Sleeper app?
http://forum.xda-developers.com/showthread.php?t=1745516
I found that it does a great job of preserving battery life when the phone is in standby. I used to notice my battery draining really fast over short periods on standby (phone would be hot to the touch). After installing this, I have not encountered that problem again. I get 16-20 hours of use on moderate usage. LTE, gps, and sync are always enabled. I DO NOT have the phone in power saving mode and I seldom use wifi. I used to get 10-12 hours of battery life on the same usage before. I am running the rooted version of the stock rom from my carrier.
CPU sleeper app works great for me. I am in a non LTE area but get incredible battery life, last all day usually with around 50% left. An order of magnitude better than my SGS2

Hi all,
I also notice this and this were the steps that I did and seems to help me to reduce this process to like 5 %. I'm on Sprint S3 but should be the same for the all carriers.
Go ahead and open Talk application. You should see your account in green (I'm not using this application) then hit the menu and then select sigh Off. Make sure that your account changes to Offline (sometimes it is change back it self so open one more time make sure that it says Offline). Then what else I change is in wi-fi advanced options: under Keep Wi-Fi on during sleep I choose Only when plugged in option. then I reboot the phone and from now on (almost 2 days) my Android system process show up only 5% of usage and my battery life improve significantly. I hope this will helps.
Thanks
Those are great tips. Thanks. I will say I've gotten increasingly better life since employing other tips discussed here.
Something else I did was download a profile changing app. I got Quick Profiles, but anything should do. If anyone uses anything better, please share. I have a profile for power saving that turns down my brightness, and turns off wifi and Bluetooth. The app will let you put shortcuts on the home screen to instantly change the profile. I'd like to find one, however, that will also turn off gps and mobile data.
