have u got spare parts? open it up and look at battery history and the running vs screen on time.
they should be the same but i can almost guarantee that your phone is still running whilst the screen is off. you need to find out the app which is keeping a wakelock on ur device and delete/change its settings

Ok thanx..will try this

Sorry for the noobish question, but can I compare the two. I went to spare parts and could not see where to compare screen on time vs running.
I recently tried to calibrate y battery, but sinse my screen does not shut off on its own as before. I've aleady checked the screen timers and all is as it was before.
Right now I am @ 4.5 hrs since I unplugged and I am sitting @ 76%, with little use...kinda sucks!!!!

What kinds of widgets do you have running in the background and how often are they pulling data?
Also, how many days have you been on CM 6.1? I upgraded from RC3 and my battery life is much improved. The first two days it was eating a lot as it 'calibrated' itself but now I can easily make it through a full days use with about 40% to spare.
I adjusted my background widgets and how often they pulled data and this really helped my battery life. Also, a poor signal can have VERY ADVERSE affects on battery life. For example, I work in a prison where cell phone reception is awful. If I am at work for 3 hours and leave the phone in 3G mode, I can easily go through 30% battery while the phone tries to find a signal...

Any idea how long will it take the batt tocalibrate???? I did the recalibration process on thurday night, and my battery sucks now.
I'm sitting on 49% only 4 hours unplugged. Before I was getting somewhere around 55-60% at this time interval...
Any ideas?

Alright boys try this. I got over 2 days worth of lifetime with this set up.
-Download SetCPU
Set your profile to 245/245 screen off with priority at 100%.
-Turn brightness to 0%
-Turn GPS off (Go to Settings->Location and Security-> turn off all that GPS crap
-Leave 3G off until you actually need it, then turn it back off after you're done with it
-Leave bluetooth off
-Don't have garbage widgets lying all over the place on 7 homescreens. I only have like 5 widgets spread out on 2 homescreens.
Are you guys running CM 6.1? Cause I am.
Did you guys overclock?
Thank me if it worked out for you =P

Convolution Thanks for the reply, but im more interested in getting a few more hours but with certain level of freedom. I am not all that interested in switching things on and off every time I need them, but I understand what you mean.
I'm looking to get 16 hours of moderate use...that should be plenty. I currently turn off wi-fi and gps since I seldom use gs, and wifi is governed by a profile manager, and it's on only at night.
but setting connection down to 2G, and killing all screen brightness renders the device (IMHO) useless. Also, SetCPU @245 100%, would really hinder the device.
I am running CM6.1 Stable and I am running OC'd @ 1497, but on "On Demand" profile, so to use only as needed.
I still have to try Pershoot's kernel, I think I will flash it tonight to see what happens.
I am also experiencing some oddity with my screen time-out feature...it's not working.....my screen refuses to turn off by itself, I have to lock the device physically for it to take effect....not sure what changed...but the regular parameters are set properly.

I'm getting 2-3 days with the stock WWE ROM that came with the phone. Brightness is set to Auto, but I keep GPS, BT, WiFi and mobile data connection off until I need them. Other than that, I talk about 20-40 mins/day, send out a few texts, listen to the radio, read my feeds and e-mail - pretty much everything the phone was made for.
IMHO, the "calibration" is bullcrap, it's just an impression that it lasts longer afterwards.

Basically the same setup I have in terms of connectivity except for data.....does it really have that much impact on battery life?
What would I missing if I decide to turn data off?
Thanks!

Huge impact. Try it out for a day or two. Or just install Juice Defender, which disables it while the screen is off, turning it on at set intervals (like for 1 min every half hour) to let it sync.

Thanks Keinengel....I'll look up Juice Defender...sounds like the right thing!

i get atleast a day and a half out of my phone and i had it for about a week now. best battery ive had for a while now.

Wow guys...installed juice defender and pershoot's kernel, and only gone 1% in about 2.5 hour....I'll report again tomorrow

Help me figure out how to improve the battery life

I am running AOKP M3 with franco kernel #15.2, turtle governor, 350/1000 w/ stock franco voltages. I also modded the auto brightness levels to ones of the MID mod. I use WiFi at home; I have set the power saver to switch to 2G after 1m of screen off time. However, I an unable to get more than 2-2.5h of screen on time no matter what I try. I plan to purchase the extended battery, but in the meanwhile what can I do to improve the battery life? I have the GSM phone.
Thanks in advance!

I've tried all sorts of stuff and 2 and a half hours is the most i've been able to get.
In order to do that I was using mostly wifi, auto brightness and I had undervolted as much as possible.
I've tried all different kernels and i've just accepted the fact that with this phone and the way I use it that's as good as it's going to get. To be honest i'm satisfied with that because in order for me to get 2+ hours of screen on time it has to be my day off, otherwise i'm too busy.
Also, i'm pulling 14-16 hours per charge with 2-2.5 hours of screen on time which in my opinion is great. I just want it to last all day and for me it does.

Try LeanKernel.
I get at least 4 hours battery life with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1200 Conservative
UV: Stock
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Brightness: About 40-50%
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
Even without the extended battery like you I would at least get 3.5 hours.

#1- people getting over 3 hours of screen time are on wifi the whole time, have 4g off, are minimalists with no syncing and no voice calls, or a combination of any of these.
#2 - based on your graph you have a lot of wake locks. Look at how often your phone is awake when your screen is off. That is KILLING your battery life. Disable or uninstall rogue apps, and turn off GPS and location services seems to help with this. Also reduce your amount of sync intervals if you can.
I have stock 4.0.2 unrooted GSM with extended battery.

Look at the betterbatterystats for wakelocks; looks like lookout kept half an hour, the rest are mostly sync.

Try to remove all widgets for a while. This can rule things out.

I'm running the exact same thing M3 with Franco 15.2 except I have the extended battery. This is with almost 0 idle time. Literally playing games, rrading forums, texting, etc.

Sorry posted wrong one. Here is my screen time.
Sent from my Galaxy Nexus using XDA App

Aww c'mon *cry*
I only have the calendar, clock and palmary weather widges (6 hour auto update). As far as I can tell Lookout and Sync are the *****es - literally. But that doesn't solve the idle drain, with the phone sleeping, it seems like 2-3% every hour or something like that.

That doesn't sound right. I have everything running as well. I don't use lookout any longer though. I'm sure if I just did the idle test I can get over a day of on battery time and still reach nearly 5 hours of on screen time. That's mostly Wifi which is suppose to drain more battery life, but I haven't seen the difference from being on 3G. This is a good set up.

I don't know if this is important but its a good note, I have not touched the performance settings or done any UV, not experienced enough, but I still produced those results.
Sent from my Galaxy Nexus using XDA App

I think you should try removing lookout. Take for example my awake times when screen is off. I sync Gmail, photos,remember the milk, and beautiful widgets.
Also major battery awake drain in beginning of my graph is due to streaming Google music when screen was off so perfectly normal.
Sent from my Galaxy Nexus using XDA App

Alright, I will remove Lookout. What alternative do you recommend, in case someone pick pockets my phone? Preferably free or cheap w/ Internet access. I'm thinking of Cerberus, as it'll be impossible for any wanna be thief to remove; I suppose the 3 EUR license is for device, right? Does it persist through ROM flashes (i.e. based on IMEI).
As for WiFi drain, on 3G it would be worse - it's longer range thus it needs more power and if the signal is bad (lucky I get top notch at home, not so at school), it's even worse.
When I get some more cash I'll order the extended battery and a dock off eBay, then I'll have a large main battery and the original one as a reserve.
EDIT: I've added the stats for this day. Better overall, the phone was used more intensively so getting a bit higher screen on time is good. I disabled Google Talk, I see it keeping the phone awake for a significant time, but I never use it. I also get rid of Palmary Weather and switched to the built in app, I'll see tomorrow how it goes.

The screenshots on the original post show sharp increase in battery drain when there is a) screen on and b) no mobile network signal.
In my opinion, these are two if the biggest culprits. The screen is obviously a power hog, especially with max brightness, and the lack of a network signal forces the phone to increase power to the radio in order to find a stable connection.

Well with the screen there's nothing you can do; A big screen will use a lot of power, a dense screen with use a lot of power, both is even worse. If this were an LCD instead of OLED the battery life with Holo would be horrible. Turning the brightness even lower than my tuned auto levels is not an option - the phone would be impossible to use due to the glossy nature of glass. As for the network, I can't do anything about that - the school building is built from reinforced concrete, that sucks up the signal pretty well and it's downtown, where the signal is already quite shoddy; at home I have a celullar tower 1km away so I get excellent reception, not so downtown.
But I'm not complaining about those. I mean the background activity, mostly the idle wake time. I'll see what I get tomorrow now that I killed Lookout and Talk, those seemed to be two major hogs.

Seems like you have a lot of awake time. Try disabling Maps, Google+ and remove all widgets and test it for a day. If it is better now, you have ruled out signal problems.

Is there any way to reduce the interval of Google sync events? (gtalk_async_conn) When I was at home on WiFi I got a sync maybe once every few hours (seen as wake). As soon as I left and turned WiFi off the sync was like every 10 minutes, which is weird, as in the AOKP ROM Control power save settings I set it to PREFER WiFi.
Why do I get a LOT more sync wakelocks on mobile data than on WiFi when the ROM is set to prefer WiFi syncs?

best pattery save I have found is turning off various radios
I use an app Profile that can turn on/off bluetooth and wifi based upon the time of day. So it turns on wifi at 7 PM M-F and turns it off at 6 AM when I leave for work. I get great battery life, and I think it is due to the radios I turn on and off.

LeanKernel stable... all the way!!... ive tried his OC 1.42/230 but you start feeling the drainage...
Sent from my Galaxy Nexus using xda premium

Believe it or not, activating wi-fi when I'm at home has actually increased my battery life substantially. No need to even turn it off; at the end of the day, it takes about 2% of your total battery life.
Care to post the "Power saving" app you are using, TC? The one that can activate 3G after the screen turns off? For so long I've been looking for such a powersaving app.

Tips and tricks: improve JB idle battery life.

Confirm the following option is unchecked:
Maps/Settings/Location settings/Report from this device.
If it is checked, uncheck it.
Here's the difference in battery life -
About half the battery drain with the option unchecked.

Thanks for the tip

What are you talking about? Did you zoom in to see screen on/awake usage? Both are about 7.5 hours of idle time.

I updated my phone to JB and followed the battery saving measures and the battery is dropping very quickly.
Before it could last up to 3 days in standby, now I'll be surprised if it lasts 8 hours.
I'll give it another day then try a factory reset if it does not improve.
Anybody else seeing this?
I have watchdog on the phone and it shows zero cpu off time.

Just install better battery stats, there is also a way to dump the same info in terminal but I don't use it. You are looking for alarms apps cause. It's most likely maps, followed by talk, exchange client, or anything like Twitter, FB,g+,stocks.... but most likely maps location settings
Sent from my SPH-L710 using Tapatalk 2

I have been doing a lot of research and the end result is that JB out of the box will eat your battery and yes disabling the settings under maps does in fact help a lot but there is a lot more you can do to get good life... for starters get the simple stuff out of the way, DELETE FACEBOOK MOBILE APP!!!...and twitter and anything that actively accesses the internet in the background... I know this may sound taxing but it is so worth it if yiu just make a bookmark in your browser and view it periodically than have an always active app... next if you are not in a primarily lte covered area set your phone to cdma only... go into settings and go to data usage and here you can see what is using data in the background I.e. facebook... and go there and check the restrict app box.., disable auto brightness and some have said that if you disable sprint connection manager thing you can do even more.... now that one I cannot be sure about I will post results in the coming days of what I find

You are pretty much correct the FB app sucks but I never really had much problems with it.
A lot of these tips though in general (not directed towards you) are stupid.
Like someone said a while ago I refuse to gimp my phone to sip a little bit more life out of it. What's the use of having a smartphone if you're not going to use it like one.
I always have high brightness unless its dark out. I broke my syncs intervals up to about 4 hours per sync and have push notifications from twitter and weather.
With those apps all I have to do is refresh when I enter the app having those syncing all the time is worthless unless you're constantly checking every 10 seconds.
I say I get fairly decent battery life granted I'm on wifi most the time and 7-8 hours with about 2 hrs screen on playing HD games youtube poweramp and my background processes.

Well in regards to the act of extending the life of your battery these are simply tips that you can utilize in the event you are someone who is out for extreme amounts of time.... I average anywhere from 13 to 17 hrs of battery life with 100% brightness, wifi 3g all of my favorite apps... instagram xda kik kindle Skype etc. And 5 to 6 hrs of screen on time. .. so these gimping tactics more than double my phones live time and doubles my life.... but hey if you can get to a charger after 8hrs by all means but for the most part I cannot until after 13 but i do in fact appreciate your incite

what rom and kernel are u using

Even with changing that setting in Maps I still am not getting the same battery life as I did with ICS. Maps is still coming up as my most used app when I check battery usage even though I rarely use it. Wonder if it may be Google Now causing Maps to keep running.

Oh wow. Sorry from my phone I couldn't zoom in. I see now lol. Thought I saw 90 and 89 or something like that

I had the Maps setting turned off for a few days and also had A LOT of stuff disabled, but unfortunately my battery life (and my wife's as well) wasn't as good as ICS, and quite a bit worse actually.
Sadly, today, it looks like I figured out what the killer is:
Google Now.
This morning, 100% charged, I turned it off. My wife (who still had it on) and I were out and about together for about four hours, we both barely used out phones for that time. When we got home I checked both phones: I was at 96%, she was at 80%.
The only difference that I hadn't already accounted for:
Google Now.
So, unfortunately, it looks to me like one of the two biggest reasons for wanting JB in the first place (Butter being the other of course) turns out to be a big battery hog I don't yet know if there's maybe some setting within it that is a specific problem or if it's the whole thing in general... maybe you just need to disable a card or change an update frequency or something (I didn't touch any so I'm running whatever the defaults are), I don't know yet... but all indications are that's where the problem lies.
That, my friends, sucks.

Well since my phone has calmed down I am getting 13-16 hr easily. Brightness maxed of course and about 4-6 screen on time I will never cripple my phone. Hell I bought it so I can use not to look at. Lol thanks for the post of this though if I'm ever I. A die hard , situation I'll know what to do

Google Now uses the "Report from this device" and "Enable location history" maps location settings to determine your driving patterns so it can suggest alternative routes and report traffic delays. Disabling "Enable location history" will disable the driving pattern suggestions completely.
FWIW Settings | More settings | Mobile networks | Network mode
Changing from "CDMA" to "LTE / CDMA" has gained me better battery life. My wife also noticed the same.

(To save time, I'm cutting & pasting my post from another similar thread.)

"I have had my Galaxy S3 for a week now. Battery life stabilized after the initial syncing, etc. I updated to Jelly Bean v4.1.1 two days ago, and battery life didn't seem noticeably different. However, that was until today. My phone was off of the charger, around 10AM, and had < 5% charge by 4:30PM. I was very busy, so I was hardly using the phone all day. It was in my pocket or on my desk most of the time. One of the only settings I changed last night, was enabling 'Use wireless networks' and enabling 'Location and Google search' under 'Location Services' in 'Settings'. I just disabled both settings, and will see if the battery drain is any less tomorrow. Also, Google Now was off, and was never enabled on my phone. I'll try to post the results, if at all possible..."
So, for me, it seems to be Location Services may have caused my poor battery life, and was definitly not Google Now, as it was never enabled. I'll try using the phone with the settings off, and see if that changes anything...

I do love Jelly Bean; as it is ICS only improved or enhanced. But battery life has definitely taken a hit. I can barely make it through 24 hrs. On ICS I could do a day and a half to two days with really light use. I've tried just about everything mentioned with little change. Good thing I have an extra battery. Thank you Samsung for making a phone with a user replaceable battery.
Thanks for all the ideas/suggestions anyways,

Hello,
as everyone im really happy with my GN2.. everyone says that the battery just drops 1% percent everyhoure..?? thats not the case with me.. it drops 10%-15%.. is there any settings you have done?? its still on stock rom didnt rooted YET
I didnt install/download any virus or fool apps from playstore (Ive read many threads but they were all the one who downloaded just random apps from playstore and that caused for battery drain..)
waiting for your answers..
ps: everyone is welcome with his settings.

Wow. 1% every hour? I won't be bothered to change my phone if that happens :silly:
A normal Galaxy Note 2 has a 1% drain every 10-20 minutes of screen-on time.
The screen-off time of the Galaxy Note 2 is indefinite. Depends on what you have on

haha when i first saw that i thought wOott 1% / hour impossible.. but when more persons said the same i thought "hmm maybe I'm wrong".. so they are ****ting maybe D
but tbh do u have everything on like google? google now etc??
now u have said that im pretty released from ma sorrow

No, I don't actually. I do not know what the screen-on time from persons' who have sync on.
I usually get 7++ or 8 hours screen-on time, from my usage.
That's with wifi, games, phone calls, messaging.

Wow. Wifi and data on? You must have super internet, man! Coolness!

I've left the office just about an hour ago... Charge was 100% and I have opened video (auto-play next=ON) playlist. Trip to home has took about 40 mins and every single second device has played videos, non stop.. No app, nothing special. When I arrived, the charge was 99%
It's probably has its very own battery optimizing systems inside which is clearly avoiding energy leaks.
I guess, I don't need anything for now to improve charge durability... Just fyi about my little test~

Hello again,
Actually our phones need nothing for better pattery durability. But if you wonder your battery specifications, i would like to recommend "Battery HD Pro" from google play market. It supports Turkish language and more.
Good luck.

The gnote2 loses ~10% an hour on WiFi and ~15% on mobile data. You can get more than 10h reading books with white text on black background. And videos on internal/external storage can get you more than 10h display depending on the video. I generally get about 10h display in WiFi and 6-7h on a workday where I use mobile data and I haven't flashed a custom kernel yet. Too much extraneous junk with the current kernels. Just looking for one that allows custom voltages on various things, mainly CPU and GPU.

I don't use any power saving apps. I have everything turned on and syncing 3 email accounts. I lose 1% overnight and rarely lose a percentage when the screen is off. What did I do? Just turned off google now and the 3 tick marks under GPS setting. Good luck!

Haha no I just don't like turning things off. I could use tasker or something similar but right now its unnecessary.

Just to share my battery drain, i play games almost 4 hours a day, rest of the time texting, maybe at most 2 hours of screen-off a day, my phone is 40% when it says 8 hours on, dunno what all you have, i have wifi, data sync, auto brightness, and well gaming, the game though are bike race and minecraft, but when with sometihng heavier like modern combat you can expect 6 hous and its 20% just sharing im stock rooted..

I agree with @akdenizx
Wanam's tips is so succesfully for battery life. I use my phone with this advice. I am happy. My phone is charged every 1.5 day by me
I want to one tip for wanam's tips.
Wi-fi sleep policy must set never.

Try using white text on true black background. Saves a lot of power on Amoled displays. The inverted colour option on the stock browser gave about 13 hours of screen time compared to the normal 7 hours

My personal experience improving battery life. (+GUIDE+PICS)

Hi,
I have been trying how to run the phone with one charge per day.
The first thing I did was getting the original OEM Extended Battery (2000mAh), in fact it improved my battery life around 20%, but anyway after that I needed a little more. The phone feels better, more "stock" than with the 1750mAh
I checked my battery stats and saw that Google Services was draining my battery, sadly I tried disabling Google Now and Location Services and the drain is GONE. It might be very radical, but where I live Google Now almost works only like Voice Search. You could add a shortcut so that you can enable Location Services when you need it (Using Maps for example)
I am running latest CM10.1 nightly with Franco's kernel 372, it works fine, the only change I have made is the min frequency which is 192mhz, I don't see/feel any lag (I ran ANTUTU and I get around 8200-8500), I haven't done a clean flash for CM10.1 since January since I use Cyandelta (I'll have to do that and it might help too). Another thing I did was editing autobrighness level, stock autolevels are too high when I am in dark places, you do that in brightness under screen. I lowered the ones under 300lx. For outside it makes no sense lower the brightness (You won't see anything hehe).
After that I was getting better battery life, but then I installed https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=es (Greenify) what a wonderful app. I set to hibernate: Calendar, Chrome, Dropbox, CamscannerClean Master, CyanDelta, Instagram, Maps, Path, Shazam, Twitter, Xda and Youtube. I still get my emails, my whatsapps and everything seems ok. You could be less aggressive than me, but hibernating Chrome, Maps, Path and Shazam is a must in my opinion. If you open the apps it works just fine!
What else?
I created a Tasker profile and it turns on autosync each hour from 4am to 11pm for 1minute. It works fine, as I don't really need to receive push emails (I think that's the only thing that Sync does). I have to test this because I think that if I don't use tasker and leave autosync on always it might be almost the same drain.
These are my results:

CM 10.1 nightlies and AK kernel latest. None of your tweaks.
Personally disabling and setting all those things up you did seems overkill and defeating smartphone purpose. Are you really away from a charger for 15 hours at a time? You disable sync but then install tasker just to turn it on once an hour at night? Why? You just killed one service but introduced another.

The important information in your screenshot is the screen on time, I could reach 17 hours at 50% with 1 hour or 1:20 of screen on..
I am reaching around 4 h of screen of time which I think is very good.
In my case sync only works for getting my Gmail emails, checking it every 1 hour is ok to me.
