Can't seem to figure out my battery

I'm using evervolv gingerbread with the invisiblek. 37 kernel and no matter what I do my battery will die in 2-3 hours with moderate wifi web browsing. Even just sitting there or messing around swiping on the home screen it will lose % by the minute. I'm using the 1500mah touch pro 2 battery so it shouldn't die that fast. I've tried everything including underclocking using setcpu to no avail. What puzzles me is I can turn my phone off and charge it 40-50% in 20ish minutes. Seems like the battery has lost its ability to hold a charge but i have no idea. Anyone have any advice?

Are you in an area with poor signal? Signal search will munch battery. If so, and you have wifi signal available, use that.
Other stuff to check:
Turn off any live wallpapers.
Check the screen brightness, turn off BT and wifi if you don't use/need it frequently, turn off GPS until needed, and look at the number and frequency of things you are synching, like weather, gmail, social networks, etc. etc.
All these things contribute to battery drain. Also, if not using wifi, toggle the sleep policy so it won't be constantly searching for available signals.
Look in SetCPU at the scaling governor for the kernel you are using - if it has a setting for ondemand, use that. Even better, if it has smartass, use that - it will scale down automatically while screen is off.

Is this an OEM TP2 battery? How long have you had it? Where did you buy it from?

I am seeing a sharp drop in battery even when on wifi. Doing anything other than idling kills my battery. I do not have the screen turned up all of the way. I do not have anything set to sync more often than the default and certainly no different than I had back months ago with froyo. The only widget I have is Fancy widget thats set to check every 2 hours.
I turned off the live wallpaper but it still sits there sucking down battery. I am in an area with a bad signal but even with a good signal it still drains way to fast.
Is there any program I can use to monitor how much battery every application is using?
It is an OEM TP2 battery that came with it when I bought it when it came out. Oct 2009 abouts. I figured it would be nice for a free 11% extra capacity.

Real world battery expectations

I usually get about 13 hours with light use with everything syncing, live background, and screen on for about 2-3 hours. What do you guys usually get?

I get a good 10 with heavy use, which is darn good for this type of phone.

About the same for me.

OK, this Android OS bug is bugging me. I haven't even used the phone at all and it's 11.30am and I already lost 55% battery life, took off charger at 5am. Guess the culprit...
I really don't want to flash some custom ROM or root yet when a stock ROM is not out or start from scratch reset but I like everything about this phone and came running into its embrace from a NS4G that I thought had a terrible battery and craptastic radio. This is absurd.
So perplexed at the moment...

I've flashed to Starburst v1.5 and I have been getting 10+ hours with pretty heavy/frequent use.

Phone is sitting dormant really with just very little use. Has been off the charger since 6:30am and its not 2pm and I am at 88%.
just checking email and doing my fantasy football updates. Little web action to unsubscribe from some sites and that is about it. Definitely much better than yesterday. Rebooted and got my Android OS taking 30% of battery instead of 54% and got juicedefender running on aggressive. Seems like my battery is super good now.

Heavy use... About 12hrs. Live wallpaper, FB, maps, gps, 4G, games, etc...
Light use.. around 21hrs. I was still at 30% when I took that pic. I don't know maybe it could do 30hrs. Live wallpaper, FB, and text from time to time...
Running stock btw with no battery helper apps or juice defenders, and Im using the "Galaxy" live wallpaper. Still, even for heavy use this thing has lasted me. Very happy with the battery life.

Here's a way to calculate your expected usage. It isn't exactly precise but it will give you a decent estimate.
Gmail/contact/calendar sync on.
Battery consumption:
1) Screen off, wifi on - 0.5%-1% per hour.
2) Screen off, 3g on, good signal - 1% per hour.
3) Screen off, 3g on, bad signal - 1 - 10% per hour.
4) Screen on, minimal brightness, reading e-books - 1% per 8 minutes.
5) Screen on, minimal/medium brightness, web browsing/youtube - 1% per 4 minutes.
6) Screen on, minimal/medium brightness, games - 1% per 2 minutes.

Me today so far... I was at school thats why there wasnt much use for a while..

Either your phone is defective, or ... Come on! I can get 6-7 hours of youtube. Streaming music with the screen off must use much less battery.
Something else is draining your battery in a big way.
In all likelihood, you are used to gsm phones, and not CDMA. With CDMA phones, having a weak signal result is a HEAVY battery drain.
So, if you signal is kinda weak, in an office or other place of work, you are likely to burn battery.
My Sprint signal is very weak at work. What I do to save battery is switch to roaming.
My secondary roaming provider has a much stronger signal. Their cell tower must be much closer..
So, the battery drain while roaming is almost as low as with Sprint with a good signal.
For CDMA phones, there's paid app in the market called Roam Control.
Using that app to switch to roaming and save battery is the only way I know...]
EDIT: Ok, I lied... I just thought a bit more about the issue.
There's another way.
You can flash a verizon PRL instead of a Sprint one. Verizon usually has a stronger (and less battery draining) signal in my area...

1% per hour at idle with no use (idle) here.
Goes up with use.
6 - 8 hours of medium duty use (web music ect)
4 hours of streaming netflix
overall compares very favorably with every android device i've ever used (starting with launch day moment (nov 2009)
this is with everything on 4g, bluetooth , gps ect. with no effort to save batt. usually in a marginal service area.

Do I have a bad battery or phone?

I get 3-4 hours battery life at best I see people saying they get 10 hours I don't see how that is possible? Is my phone a dud or what this is very frustrating. It does the samething On the extended 2100mah battery. I'm running aopk milestone 4 and glados kernel
Sent from my Galaxy Nexus using xda premium

It looks like you were had screen on for close to 2 hours and made a phone call, albeit short. This is normal battery life for as much as you use the device.

You should try manually sync or set the syncing interval as high as possible.
Wifi always ON doesn't affect the battery life unless your wireless connection is weak/unstable.
Lower your screen's brightness or use Auto Brightness.
Fully charge your phone and let it alone for 2, 3 hours and check how much battery drains. If it drains 3-4% in idle mode, it's normal. Check also if your phone wakes up a lot, maybe some apps are running in the background and they wake your phone up frequently.
Hope it helps.

I used to have really poor battery life and like you wondered how people managed to get the stats I was seeing here.
I recently decided to do a factory reset for a different reason and to my surprise my battery life has improved incredibly. Yesterday I got over 18 hours in total with over 4 hours on screen time. This was with the stock gsm battery. Granted I was using wifi throughout but I was lucky to get 8 hours before the reset, even with wifi. With 3g I'm now getting 14 hours easily with over 3 hours screen time.
My point is if you've never done a factory reset, you may want to give it a go.

It's a bit hard to diagnose the problem based on only a screenshot of your battery stats.
Since your screen is using over 50% of your battery life, my guess is that you just had your screen on for about two hours of the total two hours and forty-five minutes. It's normal to not get more than about two hours of screen time. (Tap on the Screen part of battery stats to get more info on how long the screen was on for.)
In my experience with three Android phones (MyTouch 3G, MyTouch 4G, Galaxy Nexus), all the usual tips to conserve battery life pretty much do nothing to improve battery life: turning off syncing and background data, turning off wireless, don't use widgets, turn off GPS, etc.
Pretty much there are two big battery suckers on Android phones and particularly the Galaxy Nexus--the screen being on and LTE being on. If you dim the screen or just keep it off, you will seriously prolong the battery life. And if you use CDMA only, you will also seriously prolong your phone's battery life.
That said, it's also possible something is wrong with your phone... or your battery. We can't know just from the screenshot you posted.

This looks normal. How much screen on time do you have?

My screen on time is about 1h 30 minutes with WiFi ON.. 3g/sync/gps off auto brightness

[Q] Whats your battery life like?

I haven't seen a battery life thread for the AT&T S3, so I'll start one.
Mine is around 13 hours with moderate use. I listen to podcasts for an hour in the morning (commute to work), read Pulse News and Facebook for about an hour at lunch, and listen to another hour of podcasts for the commute back home. By the time I get home, I'm around 13% life. I usually get the battery warning while listening to my podcast. In comparison, my GNex GSM gets 17 hours with the same use pattern. When I get home, I'm usually around 37%. Besides Samsung's and AT&T's bloatware, same apps, no widgets.
All told, I am very disappointed with battery life. I don't believe in underclocking my CPU in or disabling haptic feedback. I use the "Power Saver" mode, but only use the reduced screen power consumption feature (reduces framerates and brightness). WFI is always off (I don't have WIFI at work). I also disabled all of the Motion features. I disabled S-Voice (it monitors for the Hi Galaxy, and disabling also allows for a very responsive Home button).
I calculated my idle battery drain (unplugged when fully charged and not touch it) at around 4.4% per hour. That only gives 22.7 hours of standby! My Galaxy Nexus GSM can go at least 2 days (sometimes I forget to charge it at night on the weekends - also not used the phone).
Is it AT&T's LTE? Is it the Gsiff_daemon process? Is it TouchWiz? Or is it just my phone?
What's your battery life like?

You pretty much hit it right on the head. I had the extended battery from Samsung on my Gnex and could easily get 20 hours with moderate usage.
This phone despite using CM10 or AOKP with the JB kernel I never see battery life that good. I'm in the 14-15 hour range with about 3 hours of screen on time. That's with wifi off, and we don't have LTE yet. All in all, it isn't very good.

Stock? What features do you have turned off? Do you use WIFI exclusively? Do you turn off your data network (LTE/HSPA)? Did you turn off Sync?
I don't use WIFI, and I leave my data on (as it should be - just like I had it on my GNex). I also leave sync on. I understand that using these decrease battery life, but come on... not like this. The GNex faired very well, and it had a smaller battery. Besides LTE and an S4 (and the S4 should be more power efficient), there isn't much different between the GNex and the S3.
If I turn on the screen for 8 hours, there won't be enough for sleep time! It'll just die... if it even makes it to 8 hours...

20+ hrs with multiple accounts syncing at 1 to 2hr intervals, screen on time of average 4hrs. Heavy use. Wifi on all the time.

stock, rooted, debloated, super-aggressive power management I was getting maybe 12 hours with 2 hours screen time.
I saw you didn't believe in underclocking, but I started using Cpu Editor http://forum.xda-developers.com/showthread.php?t=1798765 and am loving it, can do 16 hours and 4 hours of screen time with no problems, will do the trick for me.

My battery life with stock battery sucked too. Att signal sucks where I leave and waste 30% battery in that alone everyday. I got the Hyperion extended battery and loving it. Currently at 70% when usually I would be at 45-50%.

I hate to be "that guy" but I have a hard time believing anything close to this is even possible. Can you show us a pic of your battery stats?

Just use cpu tuner, It has profiles for each level of battery life so it gradually slows down your cpu's. You can get performance and bat' life.

my battery drains a lot when i'm on wifi even when my screen isn't on. I get on average 14 hours running 1.4 GHz

You have a faulty radio.
I consistently get 40+ hours off charger with 4-5 hours screen on time with a couple hours of browsing, 3-4 hours of music, texts, an hour of calls or so, playing casual games for another hour.
Stock. No hacks. No root. Disabled all unnecessary carrier and samsung apps and disabled GPS unless i need it. Auto brightness, 2 hours sync for weathereye, flipboard and gmail syncing all the time. I do mostly use Wifi at home because my signal at home is bad and that quickly drains my battery. At work my phone idles for eight hours at a 2-3 % loss with 3G on (i use my old SIM, i do not have an LTE plan, I am on Rogers Wireless).

You consistently (or have ever got) get 40+ hours off charger with 4 to 5 hours of screen time? Do you have your phone hooked up to a car battery?

I just factory reset (wiped data and cache) the phone and installed the apps I need (maybe something was badly configured or something) - did that yesterday night. Charged it up for this morning, and now I got 18 hours and still have 17% left. Screen on time says 1:38 hours.
This is on the same stock rooted and deodexed ROM. No hotboots either, so gsiff_daemon didn't rear it's ugly head.
Also no CPU Sleeper or any of these underclocking apps. I'm happy now, but wondering wtf was causing the problem... and will it happen again (after all, this is only day one).

I'm getting about 13 hours with 5 and a half hours of screen time. Underclocked to 1.2ghz and I have my own screen off profile. Great battery in my opinion

Phone finally died. Just over 19 hours. Heavy use towards the end because I was downloading and installing the rest of my apps from Google Play & Amazon App Store. Was also setting the apps up ( accounts, settings, and notifications...). Final screen on time was about 2 hours.

It's only been two days since I've had the phone, I've gotten about 14 hrs with roughly 3.5 hrs screen on time. I hate when I see people with 2 days off the charger and ridiculous screen on time. If you put the phone in airplane mode and ran just the screen you probably wouldn't last 10 hrs unless it was on low brightness. I had the Razor Maxx and I could get around 30 hrs usage with 4-5 hrs talk and 6 hrs screen on and that's the best battery life I've ever gotten on any phone with real usage.
I would like to get better stand by and more screen time out of this phone without getting an extended battery.

Nope. Stock battery. May be some of you have faulty batteries/radios/firmwares or run too much stuff at the same time.

No airplane mode. Cellular connection is always on even during the night. Only difference is at home i have wifi on instead of data.
Flipboard, weathereye and an appsales app syncing every 4 hours. Auto sync for google account and facebook. Automatic brightness. Almost all samsung and Rogers apps disabled (except for myaccount and a couple samsung apps) and motion disabled since i have no use for the gestures apart from being a novelty the first week.
No root. No hacks. I am actually amazed. This is the first android phone that has battery life on par with my iPhone 4 and the unparalleled smoothness. My HTC One X lagged, this never does even with a few apps installed now including games. I look at my iPhone and think "why do i still keep it? It is no longer relevant".

Ive got my UV tweaked just right on my ktoonez kernel and keeping my screen level as low as can be and I'm now practically making it to TWO days battery life! Plug in every second afternoon or evening after moderate use. Occasionally it doesn't last as long. Quite happy now. Oh and that's with this baby cranked to 1.809Ghz! But obviously tweaked to use that under strain otherwise using lower clocks and deep sleeping with 384mhz.
Got a 4200mah extended battery on way and can't wait to see how much I can squeeze out of it too.

My GS3 i747m lasts around 50-55 hours per charge cycle..
It is running stock Rogers GS3 ICS, not rooted, all stock. Battery is stock as well.
Not using LTE, using HSPA+ ("4G") with data turned ON with Sync turned OFF
(**NOTE: sometimes, the battery is drained due to poor reception, and the phone will use more power for the cellular signal.. In my case, my 3G connection in my area seems alright for the most part, about 1 bar less from full)
Power saving is turned ON. WiFi powersave is turned ON.
Moderated WiFi usage in 2.4ghz 802.11g-mode only.
Every night when I go to sleep, my flight mode is turned ON. (I sleep around 9-10 hours everyday, so the phone stays on flight mode for 9-10 hours a day)
In the morning, I turn the flight mode OFF.
Bluetooth, GPS both are turned OFF
Screen brightness turned 1/4 brightness
LED notification turned OFF
Also, I have a task killer killing ALL BACKGROUND SERVICES every half hour.
Without killing all the background apps, my RAM usage is around 600-700 MB out of 1.6 GB of RAM
Killing all the background apps brings the RAM usage to around 360 MB of 1.6 GB
Without killing background apps, my battery life is shortened even when the phone is on standby.
Do this, and your battery life is pretty good..

[Q] Battery draining very fast, any tips?

Hello all,
I got my Galaxy Nexus 1 week ago, I absolutely like it, but I've had some issues with the battery...
The maximum I got is 14 hours, with 2 hours of screen-on time (the post with the 6+ hours of screen-on times on this forum made my very sad... )
What I don't understand is that Exchange Services are taking 6% of battery usage, and seem to be activated for more than 2 hours...??
Is that normal? I have 2 accounts using Exchange, but 2 hours seems to be a lot.
My accounts are not even on "Push", they are on "15 minutes".
Do you have any tips on what should I do to spot the issue, or get better battery life?
Thanks!!
Jenny
PS: Sorry my attachments are in French, but I think you should understand

well if your exchange emails are not push and set to 15min, they will check email every 15min.
set them to push if you can. thats always better for battery

That's weird, because I got even worse results when I put "push" for these email accounts. I'll try "push" again tomorrow.

I don't know what to say for the exchange, but I can tell you that I usually get 2 hours of screen on too. I was thinking of flashing trinity kernel because I've seen screen with 4 hours of screen on, but for now I haven't had time to do it

i have about the same battery life as well.
install betterbatterystats( search the forum, there's a free version in xda ) to get details on which process is eating your battery.
maybe also try to understand why those ppl have 4hrs onscreen time. their usage pattern maybe very different from yours.
and using 3G/3.5G eats a lot of battery. much more than WiFi does.

Looks pretty normal to me. I've been on 50 different ROMs and I get pretty much the same battery life as you. I also use my phone to its full potential. I don't turn of data syncing and am on LTE all day.

I don't disconnect 3G, but I don't use it much (I even don't use it at all between 10am and 6pm except the emails reception in background).
It's a GSM phone, no LTE for me.
The screen luminosity is on auto.
I'm trying today with the emails on "Push", Screen luminosity at minimum

first of all,6 hours screen on is not possible with stock battery.the maximum screen on i get is around 4hrs with 16-18 hours of battery life adjusting the brightness according to my needs.i am currently on codename android with latest trinity alpha kernel.you have to use your phone for few days until you get the max battery life.try my combination and see how it goes.

You can start by going to the settings for display/brightness and un-ticking the auto dim feature and then moving the setting to something lower. Basically move it as low as you can get while maintaining a reasonable brightness on your screen.
