[Guide]Proper Galaxy Ace Battery Fix? - Galaxy Ace S5830 General

ok i have tried many types of fixes to make the battery perform a little better on our Ace,
i seem to have sorted my problem of battery draining to 75/80% in the first 5/10mins of play.
what i did?
used phone as normal and when i get my 1st low battery promt, i turned brightness on full, screen time out to 30mins. gps on, 3g on, wifi on, blutooth on. and used google maps as live wallpaper.
let it drain battery itself till death.
leave phone for around 10mins.
turn on phone. let it die.
do this till phone wont enter pass samsung logo screen.
now even tho you cant boot the phone, you should be able to enter clockworkmod recovery 5.
now enter cwm5
wipe battery stats.
reboot system and let it die.
leave for 5mins.
now plug in your charger and charge for 5hours with phone off.
thats it, my battery life is better, 3g is on, everything else off as i dont use "wifi/gps/background data/ during work hours. been running for 2h.46mins, 20mins of phone calls and 8 texts, and only little web browsing to check a email, and battery is at 87%. it would usaly be less than 50% at this point for me.
ther might be a guide on this but i cant find it, and the ones i did try didnt work what so ever.
this worked for me so i thought i would share. battery is 100% better for me

thanks for sharing this information i need to test it what rom you use m8?

Im using DDKQ8 with AOSP beta1 flashed on top. I have used gps sat nav for 10mins since i posted. Watched 5 youtube vids. And used google sky map for around 5mins since i posted. And using wifi for past 20mins. Battery is showing 3 quarters still i can 110% comfirm that its lasted way longer than i did b4.
Typo's. Im british and its friday night. Im drunk

now on 59%
p.s wifi been on since last post
HIT THE THANKS BUTTON IF THIS HELPED x

I really don't think there's a single tangible benefit to killing the battery like that, and there are plenty of arguments to suggest it could be detrimental. And 'battery stats deletion' has been dismissed by android developers.
But I think that if you have seen a benefit from this process so far it's mostly (if not only) because of the simple process of giving your phone:
a) some reasonable time switched off and
b) a proper 5-12 hour charge.
This is good, healthy practice for any user who is constantly using their device, rarely turns it off and/or normally only charges the standard 3 hours.

dude i tried every guide out ther, this method worked for me, and its not a matter of killing the battery in bad way as you make it sound, this method emptied it the battery to atleast 1% so when you wipe stats it results in a accurate collaboration, it seems to collaborate the battery to real life standard.
as it should be, people with sh** battery life have nothing to lose, and we all have/had this issue, but i dont anymore so it helped me and im just sharing the love. if it dosnt work for you then check your scripts/oc ect. this is running realy well so far and wifi has been on but phone idle since last post and it hasnt dropped a bit. try and test
p.s 12hr charge is over kill. lowers overall battery life fast.
p.p.s im a heavy user, and i test roms alot, had my ace for 6 months now, and i Know ther is a better battery life right away with this method.
tried and tested, im using DDKQ8 with AOSP Beta1 flashed on top.
BEST BATTERY LIFE I HAVE EVER HAD IN ALL TESTS/ROM/SCRIPT COMBOS.

I'm on stock...my batt last 17hour now with 3G always on...i'm a internet addict, always online from time to time...
I use, no script!

I'm sure it does, but what I'm saying is that it works for the reasons I suggest are good in your method, and not because you kill the battery to the point you can only open in recovery, then delete battery stats. That's pretty laborious too.
p.s 12hr charge is over kill. lowers overall battery life fast.

Not really. Built in killswitch prevents overcharge. But point about longer charging is that Samsung batteries in particular are lazy at energy uptake. That's why over the course of a week the life-cycle of the phone will slowly deteriorate despite it saying its been charged to 100% each time.
I'm not dismissing your method all together, just saying some of it is good and some of it is pointless. I suppose experimentation is the only scientific way to come to a proper answer.

I feel this is not the good way to get some extra juice if we keep on doing this on daily basis then there will be a problem to battery and moreover this process takes so much time also so its better to keep charger with u. Battery stats wipe has nothinh to do with battery juice stats are for only purpose which shows which app used how much battery.

pic from this morning. still running great.

My suggesstion is leave the battery alone for a week.. Keep using it as usual.. After a week u ll see the battery becomes normal.. I stopped doing that now phone discharges normally.. I get around 17-18 HRs with 3G..

can a admin delete this post pls as people dont want to follow the guide and instead posting ther own method if any.
this works sweet for me. i have posted pics to prove its helpe. and yet no one is willing to try if they have rubbish batyery. if ur battery is fine no need to do this. my battery was ****. now its collabed properly.

I just use battery calibrating app from market, easy tho...

Options to save your battery
First, don't ever leave your phone charging overnight coz if it gets overcharged, it spoils the overall baterry lyf of your phone...
Second, The best time to charge your phone is when it's below 10%, and don't use usb cables for charging, use the real adapter
Third, Keep brightness low and screen timeout should be quick
Fourth, Make sure that You Tube, music listening, programs which runs in the background including the Sync option along with Bluetooth should be turned off whenever necessary as these too constitutes fair amount of battery drain.
Fifth, GPS as well as the Camera eats up a lot of battery, so always remember to switch these both off when not in use or necessary and specially when battery is low then it’s advised to not to use these features which can be quickly done by setting the widget shortcut on the home screen itself, touch and hold on the Home Screen in the blank area and not on any app icon and select Widget>Power Control. Add this Widget to your home screen to choose the express settings.
P.S- Sorry for my english..

I don't know if this guide is usefull or not but i want to try. If not i post the answer, if yes the same. Simply.
I have a lot of problems with the battery, first of all the random drain and fall pecentage of battery are very annoying, and i know also that this phone is not made for longest phone calls (i use my phone 2 h 30 per day for phone calls only).
So if this can't help me, i'm staying with my problems.

[Q] getting frustrated about battery life(detail included)

"Long post warning"
I have really really bad battery life since I got Galaxy S2, I tried everything, never get what people claim(20hours+ battery life).
All I have got is something around 10hrs. I already using official Samsung 2000mAH extended battery.
I never liked root and flash rom but this phone made me do it .
yesterday I flashed to LeoMar75 2.7.1 with CF-root kernel (I read this kernel has best idle battery saving)
and hoping miracle will come and now..I still stuck in battery life agony
Can you guys help me determine what's wrong with my phone? I see A LOT of fellas report their phone can run for 30+ hours with 3G always on, screen time more than 2hours, internet, whatsapp and games
I basically did the same thing , I don't even do games but mine doesn't get pass 10hrs.

today I flashed the rom and kernel and I fully charged the battery then I have like 2 hours screen time for
whatsapp, engadget, FML and stuffs then sleep for 5 hours.
before I sleep, the battery has 57% left and woke up, 33% left.
I can understand 2hours screen on time drain the battery to 57% but I don't understand why 24% of 5 hours idle?
as you can see, my device woke up while I was sleeping and it's idle.
I give you guys some details
can you guys please tell me, which part of my phone is draining the battery ?
Display setting:
1. brightness : 20%
2. auto adjust display power : uncheck
3. display mode - film
Sync
I disabled Gtalk auto login and signed out Google latitude.
I also unchecked the "Backup my data" in Privacy.
I disabled Fast Dormancy.
and here are my app list.
I already did all the tricks I can find on internet to save battery for my S2 but still the battery life is miserable. I hope you guys can help me with this : (
ps. now I doing battery calibration, I think this is my last resort , I really hope my phone can do 20+hours with 3G data always on.
yeah well first of all when flashing a new rom, must wait 2-3 cycles before the battery life is maximised....
2nd of all why the need for both friendcaster and facebook ??
If the drain is still bad I would just recommend turning all data off etc...and seeing if the battery life is normal overnight (2-3% loss)...if not then something ain't right
edit; also check your wakelocks (on betterbattery stats app)

Thanks for your advice man!
do 2-3 cycles will make HUGE difference?
I have 2 facebook account for work and friends, that's why I have both friendcaster and facebook app.
I tried turn off 3G data and Wifi at stock rom(2.3.5) earlier, the drain overnight(8hrs) was within 10% so I pretty sure it's 3G data draining the battery, just don't know which app does it. (I have quite heavy incoming whatsapp msg don't know if that's the case)
sorry I forgot to capture the wakelock screen earlier but now my phone battery is completely dead,
charging it for battery calibration, perhaps I will include it tomorrow. Thanks a lot man

Try disabling facebooks sync for a day and see how battery life is then. I ran into a serious problem where my battery was drained 50% in a matter of hours with zero usage and once I remembered that I recently updated facebook I uninstalled it and everything worked fine again. I re-installed fb but disabled sync and battery life is still excellent, haven't had the chance to enable sync and monitor the battery though.

yeah I know I have quite a lot of apps installed but that's the point for a galaxy S2 with 16GB internal storage right?
Turn notifications on for facebook but disable refresh (Set refresh interval to never). You'll get PUSH notifications instead .
are you loggdd into fb chat? If so, that should be it.
I suggest Skype.
I had Skype, Yahoo Mail, Yahoo Messenger, and Facebook installed on my phone before. Got around the same batt life as you.
Reinstalled the rom I had and installed apps one at a time. Those 4 progs are the only ones I know of I have NOT reinstalled and my battery life is usually around 20+ hrs with normal usage.
Please use the Q&A Forum for questions Thanks

If you've never logged on then your fine. Skype has always drained my battery, but I don't use it much so uninstalled. Facebook was a battery drainer with the refresh times but now that it has push (I get notifications at the exact same time as I do on my web browser) it doesn't drain my battery at all.
Average battery life is anywhere from 20 hours to 1day & 13 hours. Screen on time is always 3 hours & 30 minutes minimum, most I've had is 5 hours & 30 minutes, that was without playing any strenious games though

wow nice tips! so you suggest even I didn't login Skype, I just let the app sit in there, it still drain battery?
I disabled the facebook refresh interval like you said and yeah I still got notification from PUSH, nice tip : )
I now calibrated the battery, fully charged, did all the tips you guys gave me.
turned on the phone for 1.5 hours with 30mins screen time, (LINE, Facebook, Whatsapp only)
the battery drop from 100% to 88%, is that normal ? (I use 2000maH battery)
with the 2000 mah battery, you should be able to hit 6 - 7hours screen on time. This does depend on your screen brightness however but your drain looks ok based on screen time. Id recommend that you charge the phone to 100% before you sleep, then let it drain overnight so you can check how much battery is drained in idle. With the stock battery, I normally lose around 1% every 4 hours when idle.
As for Skype, it did drain my battery. When I logged out it ran in the background and caused wakelock issues. 3G watchdog also showed that it would use data every 20-30 mins. I'm now using droidwall to block internet for apps that don't need it. For example I won't be downloading wallpapers from the "Flikie Wallpapers" app whilst using mobile data, so I set it to only use internet when I'm on wifi

I have the same problem so i'm following this topic very carefully
Hope you'll find the solution !
one thing to remember as well, A LOT of people with 20 hour battery life have hardly touched the phone. Some people can get 3 days worth of battery, but with a screen on time of only 50 minutes its hardly surprising. I'd say anything over 24 hours with a screen on time of 3 hours is very nice.

Samsung Galaxy S2 Battery Life not good

Hi, this issue is specific to my NON-ROOTED Samsung Galaxy S2. I have seen other simsilar issues for other phones and they don't seem to help. My Battery doesn't seem to last more than a few hours. No more than 5-8 and it's dead. I turned off the Data and wi-fi. I set my Wallpaper to a Black background. It just sits on the desk and after a few hours it's almost dead...
What can I do to fix this?
Rooting is not an option at the moment.. I'm still reading and learning about it as I don't want to create a paperweight and/or void my warranty...
No offence mate but for a start you can search the forum and you will literally find dozens of threads on the very same subject which have been posted on here over the last few months.
Search and you'll find the answers your looking for, a tip freeze the Samsung bloatware in Titanium Backup and your battery life will improve substantially, there are many other methods to improve battery life you can find them yourself.
I get over a full day on heavy usage...
No offense taken, but most point to Rooting my phone...This is not an option for me at this time....I'll look some more, I guess...

I have unrooted phone and get around 17-20 hours heavy usage.
I would suggest you flash a 2.3.5 Rom via Odin as they seem to have better battery management if you haven't done so
http://forum.xda-developers.com/showthread.php?t=1075278
you dont need to be rooted to flash new roms via odin
Also advisable to charge battery till full then use till its like 1% then recharge full and so on to calibrate it a bit.
Rogue apps can eat your battery life as well so If you can afford it do a full wipe and reset if you can and see if it makes a difference.

What is a Rogue?
Chat applications like Google Talk or Facebook (if you go into Chat) tend to drain battery.

You guys need to give more information if you really want decent assistance, there is an app called better battery stats, you want to look at your partial wakelocks section in that particular app, go get it either on this forum or in the Market, post screenshots of your battery graph in Settings>About Phone>Battery Usage and click on the time, also a screenshot of your partial wakelocks will reveal the issue 90% of the time
Also, there is no need to root your phone to achieve good battery life, unless it is found that a system app may be the cause of the poor battery which is hardly ever the case, anyone who points you to rooting to get good battery life has very limited knowledge of android and what is the cause of poor battery life...
Usually downloaded apps and user settings are the cause of poor battery, there is absolutely no need to root to be able to fix those problems.....
I noticed this one too...My stock DXI2 room tend to be a battery hogger and the display consumes around 60% of my entire battery life...
agreed I'm getting nigh on 2 days battery life nowadays maybe one and a half of moderate to high usage! certainly don't need to root and install a new ROM.

Charge your phone fully and use it as you would normally, the screenshots you provided doesn't show much, what you have to do is click on the very top where it says 22h 52m, that would take you to another shot that shows your "screen on" time in a linear graph just below "Awake" time, that's the screen that would tell us if you are having wakelocks.
Secondly, get better battery stats from the market or from this link here then set the display options to "Partial Wakelocks" "since unplugged", remember you do this after using your phone normally from 100% to 50%, this should be able to give us some insight into what is eating your battery, it may be better to let the phone sleep as much as possible, but I know it's pretty hard to leave the device alone......
You should definitely try better battery stats app. It helped me to identify the app that kept my phone awake continuosly. My battery life increased from 8-9 hrs to 15-17 hrs after uninstalling that app. I even bought the paid version from market after that. Must have app!!! Give it a shot. Its free for XDA users. But if it helps you then please do consider buying it to support the developer.
yup. My SGSII is on KJ3 stock & I get easily around 1 day & 16-17 hrs before i need a charge. This is with moderate to heavy usage (depends on your perspective) which includes:
1. Display is on roughly 1.5 to 2 hrs
2. Voice calls roughly 2-3 hrs
3. 100 odd texts
4. 30-40 mins of listening to music
5. 20-30 mins of browsing
6. 30 mins of running benchmarks
7. 10-15 mins of gaming
8. Downloads for 30 mins
8. Auto-sync & background data enabled for 9-10 hrs

Ok, I had the phone plugged in to the laptop to transfer my Memo's from my BB/Outlook over to the phone, so it only says it has been unplugged for 3 min..If you want longer, let me know, as I'll do another one tomorrow.
This one is from 49 min unplugged...
As far as that app. I'll download it now and run it for a day or two and see what happens...will post back soon!
Thanks for all your help people!!!

My non rooted galaxy s ii lasts at least on full day of heavy usage, including 3g, music, and gps. Will last 2 to 3 days if i use it conservatively turning off 3g when not in use.
make sure u have latest update thats basically all i did.
good luck.

[Q] When it comes to heavy Continuous using .. which rom / Ker gives me more hours ?!

I have a very important question about the battery life
i need every extra hour while am using my phone heavily
any one tested a good rom in the Continuous heavy using ?
any rom and kerenal , original or cooked .. it doesn't matter
i mean look at this photo :

this photo with my current I9100JPKJ2 2.3.5 + siyah last kernel
the battery dead just in 3 hours of heavy using , it was :
" 3G always on + twitter app always on + some camera "
and everything else was off and automatic brightness and disabled fast Dormancy
and that what happened , it dead in just 3 hours !
so please tell me what the same conditions with your experiment
how long it lasts ?
how many hours it gives me with this using ?
i was about using TurkbeyRom , but i asked first maybe there's better one
any ideas ?
CheckROM v4 is very good.. Even with default settings...

how much screen on time? i got about 6hours max
I'm guessing you have a metric ass load of apps running/syncing and draining your battery whilst your phone is awake. If I keep my screen on time to ~4 hours I can get 3+ days (approaching 4) of life out of a single charge: Wifi on most of the time, data off when in Wifi range, sync off, every thing that requires syncing I've set to 1 hour intervals. I weeded out battery draining apps some time ago using Better Battery Stats. Your phone is asleep when your screen is off however, so that's good. BBS might help you narrow down processes but these may not show up under Partial Wakelocks.
I am on an extremely tiny ROM however and the same can't be expected of a stock or modified Samsung ROM. Disabling fast dormancy can drain battery depending on if your provider supports fast dormancy or not.

Insanity 56 + it's stock kernel. It's based off CM7 (7.2RC0 I believe), but slimmed down to 47MB.

If you want to use Twitter and Facebook apps you'll have to accept that battery life is going to suffer a ton. Good battery life isn't a holy grail or unattainable by any means, it's all in the apps and settings.

yes i know
but as you see , must people already confused me
some says it normal , and some says something wrong !!
i know it's normal when we talk about heavy " hardcore " using
but i have some hope that i can find any solution gives me extra little hours
every hour needed really in my case !
It's not a great battery profile, but it could be explained easily by screen on time and lots of apps running in the background. I guess it's a matter of figuring out which app(s) are responsible and deciding which you can live without to at least make it through the day without being at the mercy of the nearest electrical outlet. I find I can easily make the battery suck on this phone; nature of the beast.
yup i know .. but i am very confused because people keep telling me something is wrong !
some people said they got 10 hours with heavy using like mine !
Not everyone's idea of heavy use is the same, no way battery will last 10 hours with screen almost alwasy on.
Maybe you should look into an extended or spare battery instead.

No, your battery graph is normal. Every Rom, every kernel will show this result with the usage you have, don't let people fool you otherwise.

No, impossible. You can only have around 10 hours of screen-on time while doing *nothing*, I've also accomplished that once:
While on other occasions it will look like this:
So all that BS that Rom X with kernel Y will magically improve your number of hours: no. Only thing that matters is: what's running in the background, what's being displayed on the screen (dark or light images) and if you're using lots of bandwidth.
Browsing the internet while displaying a light screen: max screen-on time of around 4 hours (so: battery will be dead in around 4 hours as well). Using the phone otherwise while displaying dark content: maybe 5 hours screen-on time or more.
All that "I have X hours of screen-on time with heavy usage!" where X>5 hours is complete B.S.
Thanx a lot , now it makes seance
now i am officially disappointed , lol
ok , what about new batteries that samsung made recently
i heard that there's some improved batteries last longer than the stock one
is it true ?
sorry for asking about that , recently i am here a lot to see what is new
is there a new improved " tested " batteries made recently last longer the stock ?

My X is greater than 5.
I'd think more about grabbing a bigger capacity battery or more batteries so you can swap over to a fully charged one when you need to.
I agree with eliminating unwanted battery drain but I don't agree with not using apps we want to use.
We have an awesome phone. Enjoy it. Use what apps you want as much as you want. So you have to take 2 minutes out of your day to swap a battery who cares. Better that than having to use it like an old Nokia.

Battery issue

I know this topic is always repeated but I fly I should havr made a thread anyway. This morning, in 15 minutes of web browsing, I lost 3% battery. In 10 minutes, I lost 2%, so it seems to be progressive. I just got this phone Friday.
That can't be normal, is it? I don't want to return it but I will if its a bartery issue. Could it be as simple as buying a new battery?
Sent from my SAMSUNG-SGH-I717 using xda premium
Most people report good battery stats. Give it a week and see if it settles down. Might need a few recharge cycles to level out.
As mentioned, the OS needs a few power cycles to generate its Batt Stats to give you a more accurate baseline. Also if you need your device to last all day and into the evening with no supplimental charging, you may want to look into taking certain measures to ensure your battery life is sipped and not gulped. I am not sure your level of experience or you tech knowledge, but basically anything having to do with comms is going to suck life. BT, wifi, 2g/3g/4g, and gps are what we’re talking about. You can manage these manually or use apps to do it for you such as Juice Defender and 3gWatchdog to name a couple. My office is in the bowels of the building where reception is spotty. The first week with this phone, my battery was at 40% by lunch time. This is because it was constantly searching for signal and when it did get one, it was being forced to high power to maintain it. Since I really don’t use my handset much in my office, I decided to take drastic measures to see what could be done. I installed the previous mentioned software already to keep my data use under control (came from a unlimited plan sucking down 8-12 gigs/mon on average) so with a few tweaks it was set to assist me. So when roaming my building I check it occasionally and when in my office I switch to airplane mode since I have my email in front of me and I use Google Voice to ensure all my calls find me no matter where I’m at. I arrive at work at 0700 and stay charged in on my drive to work. So at 0700 I was at 100%. I switched to AP mode after 15 minutes of typical goodmorning watercooler talk. At 1200 I looked at my Note and it read 99%. I went to lunch and opened all connections up while in our cafateria and after 45 minutes I was down 5% with comms going and lots of email and FB browsing. I’m back in my office and still at 95%. Obviously not everybody can follow the scheduled use as I laid out, but it works for me since I don’t have signal anyways and will make day much easier when I have to do lots of running and wont be plugging in untill tonight around 2300 except when commuting. I’m hoping this trend of juice sipping continues on for the rest of the day.
Screen brightness\use also is a big juice sucker. So, with the big screen on the note you need to be mindful of that, too.
Thank you for taking your time on that long informative answer!
Asides, today at school, my phone was on complete idle standby with lowest possible brightness and Wifi off (but mobile data on) and by 2:00 (6-2 so 8 hours) I'm down from 90% to 75%.
Is it defective or is what I'm getting normal?
Edit: Forgot to add I have a Tasker that disables mobile data when turning the screen off.
Edit 2: The Tasker profile is for the screen facing down, not being off.
Still, is that not a lot?

What are you complaining about those are great numbers. Losing 1% every 5 minutes means 500 minutes of screen on time, which is 7 hours and 10 minutes. Remember that's just with the screen on. With the screen off and sitting in your pocket you will lost about 1% per hour.
2g/3g/4g...each step you take the worse it is on battery. Restrict to 2g (edge) if you arnt downloading or doing anything. There's lots of toggles. What Juicedefender does is kills the connections untill you turn the screen on and I believe periodically between screen ons to pull any texts and such. The weaker the signal strength (bars) the more battery its using in order to stay connected. Try a few things and you'll be surprised at how stepping in a little to restrict its juice use will make a difference in battery life. Plus, as mentioned, give a few days to build those batt stats up, then it will give a more accurate measure of the current capacity.

So you lost about 2% an hour. Typically you should see 1% per hour. So either you were in a low signal area which caused it to use more power to find a signal, or else you last charged it with a USB charger which prevents it from going into deep sleep (known bug). Or you could have a misbehaving app.
Download CPUSpy from the market an BetterBatteryStats from XDA and see if your phone is deep sleeping and check for wakelocks.
I last charged it with the OEM Samsung charger.
Is that the problem? The reason I started this thread is because I see people reporting (yes I know) that on standby they get great battery life.
Sent from my SAMSUNG-SGH-I717 using xda premium
Every phone discharges differently, especially when new. The overall life is what's important as to whether it's acceptable to you or not. Give it 2-3 days of good ol fashion heavy use. A few good full charge then full discharge are good for getting a good baseline. I remember one of my phones would lose it's top 10% (100 to 90) in a matter of minutes of being unplugged, but then would be fine the rest of the day. This is what I mean by the overall being the important part. But the rogue app part could be something to look into. Aften when we get new phones we go hog wild with new apps with the "lets see what this baby can do" mentality, I say this because I am very very very guilty of it. Sometimes you get an app that malfunctions or is just straight BS. There some that open by itself. Some that you get Ppush notifications about buying ingame currency for and other shady stuff. I try to install only a couple apps a day to keep an eye on weird stuff happening.
Thanks for the replies everyone.
Chief Greek, are you seeing around my results or do you think it is simply a matter of my battery stats not being correct as you said?

I have been using my method I stated in my first reply. Here I sit about 9 hours later and my phone is at 92% with no supplimental charging.
Do you know of a way to get a 4G toggle into the dropdown menu for easy access alongside Wifi, Rotation, etc?
Those are some good stats though.
Edit-One app I do have installed is "RAM Manager" and I replaced Samsung settings with settings in app. Could that be detrimental&
Sent from my SAMSUNG-SGH-I717 using xda premium
Havnt played with ram manager, although used something called cachemate before. Seemed to do the trick when phone was acting goofy or very lagged out. I would wait a few days and see if it levels out. Keep screen off when you dont need to use it and if you really really want to do something about it now, install the free juice defender and see how you like it. If you like it and want more controls, upgrade to one of their pad versions.

I loose 1% per 20-30 minutes on standby =/ What settings do you have/how many apps do you have? Do you keep Wifi/Mobile Data on all the time? Reason being, I want to get this figured out before I root/go any further. If it is indeed my own issue, I want to to get it sorted out. Is it worth a factory reset?
Not to get off topic but are the batteries from the international version and the Att version the same? Could they be a different type or manufacturer?

I am not an expert answer on this but yes, I'd like to think so. In some cases it would not be the same (being that ATT has NFC and International does not) but considering the NFC chip is NOT in the battery, it leads me to believe that the they are the same 2600mah batteries.
So, I was just with Samsung chat agent (who probably didn't know a lot about the phone) and she said lost of 25% was normal standby. Am I the only one with this? Techntreck, you get hours on standby?

ICS Battery Life

Hey everyone,
I've been playing around with some ICS roms (Energy and revolution roms) amd noticed that the battery life is AMAZING on idle/standby, but when using the phone, the battery drains VERY fast.
Are all the ics roms like this atm? Are you guys getting similar drains? I'm going to try another rom and see what happens in the meantime.
Here's a screen cap of my battery life.

I'm on the Leak ICS and I haven't seen that problem... I think it's improved my battery since I've updated.. before I would have to swap batteries half way through the day.. now I just charge when I get home.. and I work 12 hours a day.. Monday to Saturday.
After resetting battery stats this is what I saw and was impressed with. I have email set to auto sync from 7am to 6pm for work along with my gmail account, facebook set to sync once a day as I don't really care to be notified every time someone posts. Screen brightness set to auto, however this phone did not see sunlight on this day so I'm sure the screen was never maxed out.

wow, that sucks. Personally I would wipe / reflash the ruu. then slowly add applications back. Not sure what apps you have running, I have about 150 installed, however I limit what can sync. there is a paid app called better battery stats that can help identify rouge apps too.

Wow, with stock GB on TMO I got maybe 7 hours max. With stock ICS I got over 12 hours and was very pleased. I just flashed a yesterday, so I'm not sure what I'll get now, but from the drain it looks like about 20 hours or so with moderate usage. I suspect my normal day will be OK (about 16 hours).
I'm not having any problems with charging on the leak or NRG.
What does wiping batter stats do? Is it more like just resetting a timer or does it do something more like recalibrate your battery so the phone doesn't shut down your phone prematurely due to a perceived lack of juice? (when there is actually still more juice remaining)
Edit myself: according to other posts, a Google engineer said it's a myth that this does anything useful.

It is supposed to delete the battery statistics so that the device builds up an accurate battery stats file. If the stats file had statistics for a smaller battery (or poorer battery), it could be telling the OS that it was out of power when in fact power was still available. I can't speak to how well it works, but I do it whenever I flash a new ROM.

Actually, I am not sure about that myth anymore. I had CWM installed and I flashed 4EXT. My battery died within 4 hours and I barely used it. I was at 55% and I had everything turned off as well as the screen, 5 minutes later, I was at 40%. The next day, I fully charged it to 100%, booted into recovery, and wiped the battery stats. My phone lasted for 17 hours without even charging it in the day.
I guess wiping the battery stats does work?

I guess wiping the battery stats does work?

haha. Well I can confirm that it works. Oddly, it happened when I flashed the new recovery, but overall, the battery is ALOT better than ever!
You know It's weird. Battery life hasn't been great on the custom ROMS the stock RUU seems to have the best battery life.

Ditto--stock has the best battery life for me as well. Cache wiped, super wipe, dalvick wiped. everything wiped.
Left my phone charger in the car last night. Before I went to bed my phone was at 3%. I expected for it to turn off at any min so I just laid it next to my bed. Woke up 7 hours later to my phone at 3%.... I received 4 text during that time, but was not read until morning.
Stock amaze no root or s-off with ics

Tell the rom developer - I have gotten surprisingly little feedback on mine.. I tried flashing a few roms before I chose a base to work with, and the only one that didn't have any errors in the logcat, didn't have any wakelock issues, was Android Revolution HD. I've picked out every htc app I could constantly checking both logcat for errors and wakelock issues from rogue htc apps looking to keep the phone from deep sleep- and all is well.
But amazingly today someone using my rom(pdcrzylazy) posted this article on an easy flash that is supposed to "ten fold" battery life- I researched it, I made sure it flashed well.. and have had immediate big differences, even under heavy use.
There is specifically one process on how it handles memory that I think makes the biggest difference- but it HAS made a big difference! It flashes perfectly and I was able to confirm the settings took effect..
If anyone tries it you can run this command in terminal on the phone before and again after and you'll see the settings took.
Code:
sysctl -a| grep vm
The output is crazy long, so if you wanted to you can run it as an adb command - "adb shell sysctil -a > /whereeveryouwantit/name.txt"
