Ok so I'm going to tell you how to calibrate your battery, this is advised every time you flash a new ROM, you're probably asking why yourself why you would do this...
Advantages: every time you flash a new ROM your system gets confused and can result in your battery stats being incorrect meaning your phone might believe it has 0% battery and shut down despite having power left, this will fix this and so will actually give you a longer battery life
What you need:
The ability to read, and either
Cwm or the app "Battery calibrator" from Google play (I recommend the app)
OK.. so first charge your phone to 100% battery then go to either cwm recovery mode or the app, on cwm go to advanced settings and delete battery stats, on "battery calibrator" simply click the calibrate button and this will reset your battery data...
After doing either of these methods you're done, its recommended to let your battery drain completely before charging again but not needed...
I have included a screenshot of the very easy to use battery callibrator app... (having a problem with upload ill try in next post)
---I've definitely noticed that my battery lasts longer especially at staying over 80% before it would drain from 100 to 80 in literally half an hour now each percentage is equal and drains alot slower---
IF THIS GUIDE HAS HELPED YOU DONT FORGET TO SAY THANKS

There's no way to specifically see if your device needs calibrating which is why it's recommended after each flash, however if you believe your battery is draining quickly even while doing nothing on your device it's probably because you need to calibrate
Just uploaded the screenshot of "Battery calibrator app"

Clearing battery life wont give you a longer battery life. It just corrects the battery reading. Thats about it.

And other simpler way to calibrate is to reboot recovery - Go to advanced - Wipe battery stats.
When I clicked on the calibration button once it said calibrated....when I again clicked it prompted your phone is not rooted...I am running jellyblast rom....so device is definatly rooted....after some time it prompted this....moreover the app is not showing in superuser list....

The recovery method is in the guide, also this does extend your battery if your phone is switching off early because it believes you have no battery left when you do
Also to the guy who's having problems: that's normal after you click calibrate once you're done if you click it again you get that message

Yes, once you clicked it it's done, and if you click it again that happens... It's all normal, the battery stats will be recreated when you run out of Battery which is why it's recommended to let it all run out

Used my ACE without calibration (on Simplicity v3.5 Rom) - Phone was fully loaded, after around 10 min it was from 100% to ~90-85%.
This morning i calibrated and after ~10 min it was from 100% to 93% ... guess it helps?!

Yes it means it has calibrated your battery,
its giving a more accurate reading now,
P.S The only way this can help "Extend" your battery is if your phone was reading 0% and shutting down despite still having power left,
alot of people pming me asking how it extends your battery... So yes it can extend your battery.... sort of
Yeah, but i have to add:
I'm using "One power guard" atm - this app is really awesome and helps alot against battery draining - i like this, plus Supercharge, DOMscript and battery calibration - its really nice

Yeah I've recently tested this, it even has an official review by XDA, but tbh it basically just changes your CPU parameters quickly (Several other apps can do this such as frills CPU meter app) and when certain conditions are met such as low battery, this app is by far the best of its kind (Fully customisable and autimated) but ... I don't really need it my phone lasts all day even when I'm gaming... I only lose 5-10% battery ovetnight
It does have a nice layout and good features graphs etc but... meh, my phones working good already

No, not normal. I get home with like 55-60% battery left with
12 hours standby
1-1.5 hours calls
1-1.5 hours with activities that keep screen on like texting, mails, etc
i am on the ROM in my signature.
ok is there anyway to get reduce the battery drain without changing roms if not whats the best rom for battery life??

Try using a kernel that supports UV and setting slightly reduced voltages. I am using GB's 1280 kernel, and capped the speed at 1000. And reduced the voltages slightly.
Others would be normal things like switching to EDGE, lowering brightness levels, setting wifi to "turn off when screen off", etc.
what does UV mean sorry im a newb :/ and how do u install a different kernel
mac3194 said:

UV = Under volting
1. Load the kernel in my signature (attached to this post)
2. Install the voltage control app (attached to this post)
3. Start the voltage app and set the voltages and cap at the levels based on the pic in this thread.
WARNING: Voltage levels depend on phone to phone. I would suggest starting from low values. Take off 50 from the values I have posted in the pic and use them. If u feel it is ok, then add another 25. Take it slowly checking if the reduced voltages are freezing up ur phone.
I would recommend u starting with these values: 75 75 50 25 25 0 from bottom to top.
Ok thanks diablo I will test this out tomorrow and report back

Sounds like a good old battery recalibrate is in order:
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
I did this a couple days ago, plus wiped stats, and as of right now, I am showing 20% after 30 hours. No joke.

Ironically, JuiceDefender killed my phone *much* faster than with me manually enabling and disabling my data connection.
IMO, JuiceDefender does nothing that you can't do yourself, the problem is, is that it constantly has to check apps to see if any are enabled to toggle your data connection.
I am just saying

I actually use my phone and I am getting these results
I have a very similar question. My problem is, on custom roms (I've tried Assonance, Serendipity, and another), my battery drains 1%/hour. This is even after a fresh install; nothing is running in the background. When I look into my battery info, it says wifi is doing the draining. I keep hearing people saying their battery life is amazing after flashing custom roms, but I'm getting the complete opposite. Am I forgetting something?
Without custom roms or anything, and using a rooted/lag-fixed (not sure this makes any diff anyway) setup, I lose somewhere between 2-3% battery per hour on standby. I don't even use juicedefender. I really love what they're doing with these custom roms, but the wifi on standby just rapes my battery.

Set wifi sleep policy to off while screen is off
i dnt even use wifi and after 5hrs of use my battery is at 74% which is good enough for me but i wouldnt mind 1 day+ of battery life... how do u do this??
hello guys..i am opening this thread so some people here can test this for their custom roms!
Devs need to test something if its related to Clockwork or the Usb cable that gives different values of voltage upon charge!
i am not a dev..i am just suspecting something so the next kernels could be better checking more closely somewhere here about voltage or something related to that!
Do this steps (credits goes to tetsuo55 for providing me better steps!thanks tetsuo55..)
1. Install Paul/Modaco Clockwork mod
2. Install ROM
3. Install Rom-Manager
4. From within Rom-Manager choose the option to "Flash Clockwork" (Replacing Paul's)
5. Reboot into Recovery (hold power and volume down)
6. Go to the advanced section and Select the "Wipe battery stats" option, then select "YES"
7. Go back to advanced and select "Fix Permissions", then select "YES" (this will break a lot of stuff like fonts and some applications's data)
8. Go back to advanced and Select the "Wipe battery stats" option AGAIN, then select "YES"
9. Reboot and charge to 100%
10. Drain the battery until the device loses power
11. Charge to 100%
12. From now on try to keep the cycle 20% > 100%
hope to work also for you guys !!
if this was helpful and worked for you just hit the thanks button!
i have looked into your post.
as I know, wipe battery stats force a reacknowledge of the battery properties from the OS, and...
oh crap
i'm loocking at the battery, one of the logos say "keep below 40°C/104°F" but.. in charging and or heavy use this temperature are easly reached (without any overclock)
anyway, with FR15 seem's that the charging "overheating" is gone.
i will look into it
EDIT:
i'm running the phone with minimal background service, and have the same discharge as update for all on 15 minutes.
i wil try a wipe battery
Following these instructions i must have lost my fonts or something, because both my launcher and settings don't show any text.
Any ideas on how to fix? (im using fear 8.1)

i hope you did some backups before you did this!
Yea, just restoring backup from day before yesterday... should work. We'll see
Before that I tried to flash again [email protected]'s 1.5 ROM, didn't solve the problem. I was using stock font, weird...
I'll let you know after restoring

be sure to remember with which one clockwork u did the backup beacuse at start you are flashing the custom rom with pauls clockwork and then installing the clockwork from rom manager! maybe u have to put again the pauls clockwork for restoring the backup you did!

Clearing your battery stats is a well known method of improving battery life (up to around 30% apparently) and there's countless guides/posts about it.
I did the fix a moment ago, no problems with fonts or something else.
[email protected] 1.5 + ubuntu fonts..
2X is pluged in and battery is loading..
Hope the fix will take positive effect to my battery life.
I forgot to make a backup. but modaco 16 is around the corner.
The steps corrupted the currently selected font, so i can use any other font except that one.
It also broke synchronisation of all apps like whatsapp, but that gets restored once you use it.
So far i have not noticed a increase in battery life during usage.
Confirmed..its lg‘s usb cable problem related!!with adapter!i lost in one hour in standby mode 5% of battery! I will charge it again with original htc wildfire a/c adapter and usb cable to confirm the different between lg‘s a/c adapter and usb cable!

I too lost fonts after fixing permissions. You can just change the font and reboot, IF you can remember how to get to that setting without any text .

What are you saying?
1. The steps above don't make any difference, the problem is related to the LG wall plug adapter
OR
2. On addition to the steps above, the wall plug adapter used also has an influence on the total battery life. It seems that the LG adapter confuses the battery.
???

EDIT: it seems to work. Currently the idle drain is 1% per hour
EDIT2: i can change the fonts, but if i re-select the font i used for the commands above i again see nothing. Also lost contacts facebook intergration.
Wow..thanks buddy for this workaround!!i was kinda feel bad for those who had their font broken and i felt like that it was my fault!i am just tryin to help improve the battery life ana with your contribute and your help maybe we will find a solution till the stock LG gingerbread rom comes out to fix the problem with battery draining..!

Original link: [APP] Battery Calibration - EASIEST WAY! - Version 1.2 (10th April, 2011)
I just posted here so that Nexus S member realise that they need to calibrate their battery before giving comment that they having bad battery life
[APP] Battery Calibration - EASIEST WAY! - Version 1.2 (10th April, 2011)
Battery Calibration
[APP] by marosige
version 1.2
Requirements: Android 2.1+ | Root permissions
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.
The voltage meter can be useful too. Full charge is around 4200mV.
There is an option to beep when 100% is reached so you don't have to closley follow the changes.
EXTRA NOTE FOR NEXUS S:
Since our Nexus S has default of charging limit till 95%,
we'll need to do some setting modification to enable it to charge till 100%.
1st, Go to Setting, select Display, change the ScreenOut Time to the longest (30 minutes for mine).
2nd, Leave it there and charge it, remember to touch the screen every 30 minutes to enable it charge till 100%.
3rd, When it shows 100%, open the Battery Calibration apps and press "Battery Calibration"
4th, Reboot your phone and it should be alright
(You maybe asking why when the screen is on, it can be charged to 100%, I have no idea too

Does this really worth the trouble? My phone charges up to 97% and the batt least long... On CM 7.0.3. Does it really increases the life time?

Do you need to do it every single charge? No, you dont. Would it be a good idea to do it the first time after flashing a new kernel or ROM? Sure.

Well, that's good if you can delete battery stats.
This apps is for those who LAZY to delete it, instead, use a apps where "one-click" is able to achieve it without going to recovery mod
Something I don't understand about the Nexus S note:
if you can't charge your phone above 96% how could you let it charge until 100%?
If I let my phone charge during several hours, the percentage doesn't increase over 96-97% ...
So could you explain a little bit better.
Thanks a lot.

The weird thing is, when the screen in on, it can be charged to 100%
Ask me why? I have no idea too. Haha. You try it and you will realise it
I found out something more than weird ... if I let my phone charged with screen on, I can't go over 97% and the battery state oscillates between 96 and 97% !!!!!

For me charging with wifi tether turned on it will charge past 96%,without it on it stops charging screen on or not. I got to 98% this morning before leaving for work or I was gonna be late...
sent from the nexus of the 4g universe
mine tops out @ 98% like this.. cant get it to 100
With WiFi tether I can get to 100%. It may be something to do with not letting the phone go into a 'deep sleep'.
Sent from my Nexus S using XDA App
Hmmm... so I let it charge to 100%, then recovery, clear battery stats, reboot. And when it rebooted 95%. Afterwards I recharged my nexus back to 100% and now it seems to be charging fully everytime, or so it seems.... That's so weird, why a charging limit? Software Bug? Or am I just an idiot and it takes 5% battery life to reboot into recovery..
Edit: Now when I clear battery Stats I get no confirmation in Recovery, it just jumps back to menu..... Ill give this Battery Calibration App a try and see how it goes, cheers
I noticed this error, the inability to charge beyond 97 as well as showing decreased charge while plugged in, and left my nexus plugged in and off for 6 hours...
it booted and showed 95% charge, but reported full... Strange

Please remember that for our nexus S, 99% and 100% can be consider full charge as to 4198-4200mv. So when it reach 99%, you can just unclick the "wait til 100%" and click "battery calibration"

Hmmm... so I let it charge to 100%, then recovery, clear battery stats, reboot. And when it rebooted 95%. Afterwards I recharged my nexus back to 100% and now it seems to be charging fully everytime, or so it seems.... That's so weird, why a charging limit? Software Bug? Or am I just an idiot and it takes 5% battery life to reboot into recovery..
Edit: Now when I clear battery Stats I get no confirmation in Recovery, it just jumps back to menu..... Ill give this Battery Calibration App a try and see how it goes, cheers

I noticed when I clear battery stats the very first time in recovery, it never show comfirmation. Probably due to some bugs I guess?
So I share this app as this app does the job
Also, a little tip.
Go to Settings>Applications>Development, and press stay awake.
Makes it easier I guess, then you don't have to monitor the phone.
Hello friends.
Using o2x from 2 weeks.
Tried lot of roms, all kernels etc.
but what i get average 1 day use of phone, 17 to 20 hrs (less 8 hrs of sleep then it comes to 9 to 12 hrs). with normal use.
1 hrs calls, 0.5 hrs data and remaining is here and there sneaking in phone.
i never used gps,wifi,bt etc, all are in off state.
.
now i m currently on cm7 kang by temasek with irnkernel.
still battery giving same draing.
draining 1% just in 3 to 5 mins when i m using phone (not on call or data).
and main point is i m on edge coverage, so no 2g use.
data is always off.
.
i dont know what eating my battery too much..
.
realy, i m getting upset.
i tried every kernel and every rom, did battery calibration etc.
.
Update : I forgot to mention i m using class 2, 16 gb micro cd card.
also i m using acer liquid metal's usb charger for charging.
will this affect on my battery ?
update : guys i want to mention one thing.
today i pissed of with this problem and thought it was battery problem.
so i planned to go customer care.
then turned back v20e which official 2.3 for india.
then i saw dramatic changes in my battery drain.
it was half as before, with stock thing, no apps installed, not rooted etc.
i m still monitoring my battery.
.
also one thing, is go launcher will be cause for this ?
cause when flashed with v20e. the widget show drain as around 130-150 mA.
then i installed go launcer ex, then drain was 250 mA.
.
what is ur normal drain when u r using phone ? (for those who r getting best battery life)
.
.
can anybody share his battery drain graph which taken by battery monitor widget ?
here are some screenshots :

I have a similar problem, but it's likely because of 3G. With V10F Froyo, the phone drained <1% per hour in stand by, with 3G on. With V20L, and CM7 (any version of them), my phones draines 3-5% per hour. Tried anything, any ROM/BB combination, returned phone to warranty, but nothing.

OMG u r god!
how the hell do you have such a battery life?! even I am on temasek's kang!! at avg with your kind of usage it will go for less than a day :/
same with me..
hardly a day..
is there any problem in indian phones ?
See that 'better battery stats' image you put up? See the drop down menu that says 'since unplugged'? Change that to 'partial wakelock' and get a picture of it to show us the result
Also, you seem to have a lot of battery apps on the go.. are they conflicting?

I had a problem with huge battery drain and the culprit was my sd card. I dont know why but it had problems scanning it so I think it got stuck in a scanning loop of some sort. When I removed it, all was fine.

i m getting angry on my phone.
see guys, i slept over night with 100% battery, just wake up n saw it wa 99%.
then used phone for just 20 mins.
and now battery on 92%.
now tell me friends, what i need to do ?
Do you have apps like juice defender? Accuweather? Uninstall them. They are probably eating you battery without you seeing.
See your running application?

nope.
in provided ssi was using jucedefender.
later i removed it.
same drain still
Perhaps you need to calibrate your battery (using baterry calibration app) and wipe the battery stats (via cwm)

i did it already.
My recommendation:
1. Flash vadonka's kernel (ironKrnL has good performance, but drains battery fast).
2. Remove widgets which keep accessing the net in background, stop background data over network (in settings)
3. Install AnTuTu battery saver and set battery saver level to level 2.
4. Remove SD card. Try to manage for a day without SD card. Set internal storage as SD card in CM settings.
5. End all background apps after using any app (use dr. battery saver or similar app to kill all apps).
6. Take any other precautions, such as lowering screen brightness, tick "use only 2G networks" option, dont allow automatic email syncing in background etc.
Try this for one day on a full battery and let us know the results. If it does not improve much, you probably have a defective battery. I also own this phone in India and my battery easily lasts 2 days on normal usage.

Thats normal i think. Get nearly the same results.
Try Rugglez suggestion.
Also check if your Baseband matches your RIL.(Download GetRil from Market)
And go into Settings --> Apps --> Running Apps and check if there are many Services running in the background.
Also you can try to install the Autostarts app, which lets you control which apps are allowed to open themselves in the background.

will this affect on my battery ?
Alright so like many other people on this and other forums, I updated to ics 4.0.3 two days ago and been experiencing battery issues since. But my battery issue is a bit different from what I've read about. My note has no problem going into deep sleep, when i go sleep and wake up deep sleep is at 98-99% and my battery drains about 1%. But when I turn on my phone and start using it no matter what I do, the battery drains about 1% every 3-5 minutes.
Phone settings:
- I always have my brightness at 0 and have screen filter on to make it even less bright(even though battery drains about the same with or without this on) (batter settings still show that screen is taking up most of the battery)
- With wifi on or off battery drains just as fast.
- I havnt started my new data plan yet so im always on airplane mode( battery drains the same with this on or off)
- My note was never rooted
- I basicly have no widgets on anymore because i deleted most of them but doesnt help battery life.
- With power savings on or off battery still drains the same amount
- The only apps i have installed after ics are ones from googe play(netflix, chrome, and other simple apps)/ i deleted my emulators and other apps that iv'e downloaded and installed
Can anyone please help me with this issue
bump
You are on Stock ICS ? Go to Settings>Battery And Post the Screenshot Here. It will help us to determine the exact situation..
Sorry I'm new im guessing stock ics means official release from kies, then yes. I dont know how useful these battery ss will be because a lot of the time im either idle or charging.

Did you perform a hard reset on your device after the update?
if not, then see if you can try it and get back again with your screenshots.. don't forget to do some re-calibration also on your battery. This works on my end before. Not sure if it works on yours, but hey.. there's no harm in trying right? just give it a shot bud...
Cheers!

Turn off the sync. Kill Background applications and See if it works for you...
Also download Battery Calibration from play store... Open it when its fully charged and start calibration... Let your phone battery fully drained and then charge it again to full without pauses...

I've been thinking about it and it would be my last option to do a hard reset because i read that some people bricked their phone by doing it. =/

I have sync accounts off and i only have my gmail account in the options to turn it on unless you mean something else.
I'm not really sure how to kill background applications is it the cashed applications? because ive tried killing running + cashed.
I just installed battery calibration and it says i must root my phone 1st =/

Wtf are you trying to brick op's phone? You should get a warning..
Op never ever ever ever ever ever do a factory reset from ANY ics stock kernel.. It will get your phone bricked.. Or maybe but just maybe not? Anyways will you take the chance?
I was on 4.0.3 stock and yeah the battery it's horrible.. Don't know why the phone barely goes deep sleep.. Check this with cpu spy free app from market
Since the phone upgraded itself to 4.0.4 I have been able to run 14 hours with 5 hours screen and the phone its always on deep sleep
Sent from my GT-N7000 using xda premium
yea i knew theres a huge risk involved =/ , is there anyway i can update to 4.0.4 because it's not showing up on kies
Yeah following the several guides around.. They all lead you to download 4.0.4 and a gingerbread rom from Sammobile, downgrading your phone to gingerbread by flashing it via odin and then flashing ics 4.0.4 via odin also .. So go ahead and read some..
Cheers

Check Android Development Section...
cpuspy and betterbatterystats to check partial wakelocks and whats keeping phone awake. A gazilion threads on that. read them. You need these as Samsungs analytical view state nothing usefull, they need to fire the designer of that.
Next to this I see lot of screen on time, how much time roughly is that in total, you are actually using device?
Sent from my GT-N7000 using Tapatalk 2
my phone doesn't have the deep sleep problem people have. my on screen time is about 6 hours before it drains completely and by on screen time it could be on the home screen with no wifi/net and no apps running with just the screen on, and the battery would still go down 1% every 3-5 min
So ics 4.0.4 came out for the UK version of note so i updated via kies. This didnt fix battery life at all, in addition iit came with another bug where my phone gets hot and drains battery when turn off the screen after playing any media file....So my question now is can i root 4.0.4 if i have the Emmc bug?
