You need to give more info then that.
What version of rom you using?
Which kernel/version you using?
What apps have you installed?
Do you use wifi/gps?
Did you use search before creating topic?
btw, you dont need to manually type [q] in your title. "[Q]" automatically gets added when you enable the "Is this a question" feature when creating topic.

i'v 144 Apps .. neither the widgets .. do you want me to name it all .. idk someone did that before right .. btw i don't use the Tab during am writing this comment but its still sucks the battery ..
and yes i use WIFI .
overcome tell us the solution for the battery life . but the solution didn't work with me
anyways thanks for ur reply .
btw i didn't type [q] i just thick the ' Is this a question ' ... tnx for your advice ..

I have actually noticed a decline in battery life since I flashed to Overcome. In the few days, before I flashed my tab, I could idle the tab for 10 hours and use like 2% battery. After flashing overcome, I cant get no where near that idle time, and I get just under 10% per hour full usage (games or video playback).
I'm using Overcome 1.6.1, no live backgrounds, and somewhere around 85 apps.

Strange, Ive never had a battery issue on any of the builds, even when overclocked. Its got to be something you have installed and running in background.
Go to settings>phone>about>battery use and it will tell you what using most battery. There is also programs like SystemPanel or Taskkiller etc.
If the [Q] wasn't capitalised then you must have tried to title your topic all i capitals so site reversed it, next time title topics properly

1st of all . the battery charges take so many time to charge full even though if its 95 its take around 15 to 20 mins to full charge .. and when i take the charge it give 99 even if its says the charge full ..
if my tab is off screen its also suck my battery life seriously .. i don't use live wallpaper i only use a normal image .. i don't know what is the problem .. am really thinking to replace overcome .. the prob is i like overcome even if it doesn't support arabic
any ideas

I never got any problems with the battery life in all Overcome roms.
Currently i use Overcome 1.6.1 with 2.1.4 kernel and battery life is good.
Idle overnight with WiFi enabled it uses 6%
Idle overnight with my dataplan it uses 3% and idle time is approx 12 hours.
In the idle time i have my Gmail synced, twitter, weather ect
In full use and full display light i can use my Tab for approx 6 hours.
I have to mention that my Tab is not Oc-ed

i just woke up the battery is full and its showing its full
what comes in my mind now
i turn off the tab to charge and see .. i off the tab i plug again the charger and guess what ... its still charge since 10mins
i'll do again wipe battery status and see .. this is the 4th time i'll do the wipe for battery .... i don't know what is the prob
so i wipe the battery but nothing happen .. so i just backup all the stuff ... going to re flash again
wipe data , wipe factory reset ...
flash again the rom and the kernel ...
.... i hate my tab cuz every week something new need to flash need to wipe need to reset
EDIT .. flashed again with wipe factory and factory rest and nothing happen after i flashed the kernel and the rom

My battery seems to drain fast too
I updated to Kernel 2.15 and Overcome 1.63 last night. It seems to drain 1% every 1.5-2 minutes when I use it with WIFI and 3G on. It drained 6% last night over 6 hours on standby mode (after I shortly pressed the power key).

I know there are some Gallery issues which drains your battery after using it.
But other then that i think some people expecting to much to fast to see some battery life progress on custom roms.
On the first fresh install i had also a drain.
You have to be aware that after a fresh rom install you have to let the battery settle for a couple off charges.
Yesterday i also took a complete reinstall by the guide provided in the Overcome thread.
I did this because i have some issues with FC's on receiving gmails.
After that fresh install and restoring my apps ect.
I went playing with it, first i did 2 hours of surfing over wifi.
Later playing Black Pegasus Modern Combat for 3 hours.
I started of with 67% battery and didn't have the battery calibrated
So after 5 hours of heavy use the Galaxy Tab battery was empty.
This morning i calibrated the battery.
And after a full cycle charge in 2 hours i didn't touch my Tab at all.
After 4 hours i still have 97% battery left.
It is common that when you take your from the charger it instantly drops to 99% (No worry)
So 2% lost in 4 hours in idle standby with 3g on and syncing XDA app every 15min, Twitter every 5 min, email every 30min, Gmail (Push), weather every hour.
I think it's battery life is great.
Beware the screen of our Tab's are using a great deal of battery life.
Even 50% brightness sucks your battery empty.
I have it set on 30% which is good for use in the evening.
Daytime and sunlight it sucks at 30% but since i never use my Tab outside it will work for me.

Hello!
I cant imagine that the battery is draining because of overcome rom or kernel. Since i flashed it my battery life is suprisingly good, even when overclocked!

Same here...
I know there is a Gallary 3d issue when using it your battery is draining.
Alterbridge is working on that.
If people followed the flash and battery calibrate guide Overcome should have a nice battery life.
I don't know what apps people are using at the moment but it could be an app which is poorly written.

guys im flashing overcome even before the guide posted ...
and about the live wallpaper .. i don't use it .. because i use a honeycomb theme
and about the calibrate of the battery i already did it many times from overcome guide or even from the apps in market .. i knw wat am doing .. i never get on in something that i don't know wat exactly means ...
cheers

Poor Battery Life On Overcome Jupiter

Hi,
I don't have sufficient posts to be able to participate directly in that forum, so have no other choice but to raise my queries here.
I've just flashed over from Overcome "Hermes" to "Jupiter". All's well except that the battery performance is quite drastically affected for me.
I've been reading the improved battery life "Jupiter" gets over earlier versions of the Overcome ROMs, but I seem to be experiencing the opposite.
Already did the batt stat wipe via recovery menu. Do I need to so call "run-in" before it reflects correctly? Even if accuracy is one thing... but dropping 3% just on bootup.... is this typical of an uncalibrated battery?
Appreciate any advise here on what I should do. (Apart from a fresh wipe install )
Thanks

I appreciate the enthusiasm these coding geniuses have in rolling out update after updates in the ROMS yet I am apprehensive about the effect of these frequent flashing on the Galaxy Tab components itself. This includes the battery.
My job involves electronic repair and there is a so called number of hours before an equipment goes for a thorough check(preventive maintenance) say for example 1000 hours on a meter. Unfortunately the galaxy tab (or any tablet) does not have this. So if you frequently do a flashing on your tab you subject the electronic components to unnecessary stress,thereby affecting the life of the components like the battery.
In "normal" everyday use of the tab you will seldom do any restart/reboot of your tab,yet in flashing ROMs as many as 3 reboots is needed. As I don't know how to measure the surge in current during reboot, I can just imagine how high an initial current during startup is generated, thus putting a big strain on the battery.
Unfortunately the battery is not user detachable.
There was an author here in XDA describing himself/herself as an "flashing addict"(or something similar). I would like to appeal to everyone-please don't be a flashing addict.

According to the Tweaks section at the team overcome website, it will take several charge cycles before you notice an improvement after the stat wipe. Try giving it a few days before going any further.
PS Not to question your ability to follow instructions (sometimes we miss things) but did you charge to 100% with the tab off?

Yes, I did charge to 100% with the Tab off.
Now upon reading the instructions once more..... I might have conducted it slightly different from the written procedure.
I unplugged the Tab from the mains, then only booted up and wiped the batt stats before re-booting. Hmmm.... maybe I'll go try booting up while still plugged into the mains, do the batt stat wipe, and re-boot. (all while plugged into the mains). Then only unplug the charger.
Wonder is there any diff in doing so.....

Would definitely try re-doing it with the tab plugged in while doing the stat wipe. And if it doesn't seem to fix it, do go through a few cycles before reverting back to a previous ROM.
It's important to completely drain your battery before recharging it to 100% in order to complete a cycle.
Hope you fix it. Battery life results vary between tab's even if they are used very similarly, I'm running the OVERCOME Jupiter ROM with IMPROVED battery life. I keep my Bluetooth, Wifi and GPS on all the time. I also flash quite often and have not seen a decrease in overall battery life. It seams that each tab is a bit different, hardware wise, than one another. Everything from battery to board it seems is slightly different coming out of the manufacturing process.

Thanks. Will try that out.
But it just seems strange coming from Overcome ver 1.4 (Froyo) which had no batt drain problem.... to Hermes which was better in batt performance.... to Jupiter which I'm experiencing heavy drain.
As I did a NoWipe install, all apps and setting are similar (except the new market app).
I was able to run 2 movies back to back (about 3 hours total) and still have at least 40% life left (usually about 45 to 50%). Now on Jupiter, just fiddling around testing the various features for functionality, plus maybe an hour of NFS (total about 3 hours as well).... the batt drops to about 10% life.
Anyway, I'll re-do the calibration and and give it some time to "settle in". Hopefully, that is all that is needed. (I would hate to have to do a full wipe install... and re-installing all apps)

As mentioned in the Tweaks section, perform the Stat wipe and then two full recharge cycle
recharge to 100% (while the Tab is closed) then drain the battery till it is off then repeat the cycle and you will enjoy it man
Please tell me if you need anything

Viewed purely from an engineering perspective, I'm unable to see any significant connection between the flashing of the ROM and a degradation of battery capacity. Further, in the event that the TAB was connected to a charger during the flashing, I can see absolutely no connection at all! Please help me understand your logic.

Ok Back on topic. PCdumb (dude what's with the username lol). Check your app list. It could a new app you or an old app you updated or an app you didnt use before but you use now that is being a battery hog. A small trick I learned is checking apps running services in the background. Go to Settings, applications, running services and check (why is skype working after Isigned out its not a battery drainer but I hope you got the picture).

Thanks for the advise. That was one of the 1st few things I did to check that there's nothing out of the ordinary running in the background and taking up the juice.
Mine's actually draining alot when in usage. Not too sure about when in standby.... will check later.
If after a few charge cycles and the drain is still bad, guess my only next best option is to do a full wipe, re-stock and re-install.....

I did not get any effect from Battery calibration. As expeced. Anybody did actually?
The background services instead might have an effect on power consumption, I agree. But needs numerous testing...

Batt recal did not give me better battery life. There's no difference in the battery performance after 3 recharge cycles.
My tab can at most get slightly more than 5 hours of continuous usage compared to about close to 7 hours on hermes. This is when i dial down the OC from smartass mode to conservative and also put the min freq to 200 instead of 400 which was the setting i was using all the while.
Doesn't seem to be anything else running in the background. On standby overnight, i only lose about 3% which is not too bad. But when in use, that's where the Batt drains fast. Just for comparison, i only lost 1% at most for overnight standby of about 7 hours when running hermes.
Guess I'll have to live with this if i want the speed and smoothness. Still contemplating whether to restock and do a clean flash.

If you want to confirm that JUPITER is the reason that you are experiencing poor battery life, try re-installing a previous version that you feel worked better for you. Maybe reverting back to a previous version may yield better battery results, and I sure hope so, this way you will know if it's the ROM or other elements affecting the abnormal battery drain.
If you do see an increase in battery life, try flashing JUPITER again, see what the results are. I don't know if flashing and re-flashing will have a negative long term effect on your SGT, I know that I flash every time a new release is out (Stock safe, cooked ROM, Kernel) and if i'm not happy with the release i go back to a proven one by flashing another three times (stock safe, cooked ROM, Kernel) and so far I have not had any (knock on wood) abnormal battery activity.
It's worth giving it a shot (if you haven't already).
EDIT: I know, I know the proper sequence is stock safe, kernel, rom.

after week of using the Overcome ROM i can confirm that the battery performance is between 85 and 90% from the Orignial stock ROM performance
No problem since this is normal as we are using a cooked ROM

I do get 4 to 5 hours of continuous use with overcome Jupiter, mostly browsing the web over
WLAN or umts. Hermes release didn't gave me so much more juice, probably 5 hours.
In the background I have emai push, contacts and calendar sync and some instant messaging apps, if I switch off all that I might get an hour or so more.

Wow, maybe your tab is one of the ones with a battery from the bad batch, and it's finally on its way out. I upgraded from the stock AT&T Rom to Overcome Jupiter, and on Airplane Mode with all stock settings (no overclock or undervolt), mine only drops 1% in standby over 14 hours and I can get about 5 hours of video watching straight with the brightness on max before it dies!

I also been experiencing a major increase in battery drain even after doing a couple wipes exactly according to the tweak guide. I went from about 24 hour normal use down to 6-8 hours normal use.
Checked the services as per your suggestion above and found a couple major battery drainers running. Skype and Yahoo but also Google+. What I dont understand is why Skype and Yahoo would be running even though I had not started either since at least several re-boots ago. I had Skype and Yahoo installed for quite a while Google+ is a new one. Anyway I killed all of them and now and will see what happens next.
Not sure thought that this is all there is to the issue. Recahrging is finiky as well. I can turn off the tab and let it charge all night just to find that it charged to about 70% if I re-plug it might charge to 90%-95% and then if re-plug it might get to 100%. The drain from 100% to 60%-70% is extremely fast and still quite fast from there. On one occasion after complete drain I couldnt get it to start charging at all for about 5-10 minutes. I was checking power, cables, connections and starting to panic when all of a sudden it started to charge.
Any advice on possible reasons or solution woud be appreciated. Not sure I want to go beck to stock ROM and un-root just to take it to service center for repairs.

[Q] [i9000] Team ICSSGS RC3.1 - Battery Life

Hello everyone!
I've installed few days ago the onecosmic's ROM RC3.1, beatiful, perfect, smooth bla bla.
The problem is: i'm seeing so many post of people saying that with full charge, phone can stay alive for an average of 1 day- 1 day and an half (24-36h) with a normal use.
My phone can last 13-14h staying most of the time in standby and it's the 5th cycle so should be "stabilized" now. 1st cycle was awful, 8h (didn't expect anything else), then things got better but i've reached this cap of 14h.
I've tried Fugu kernel at first but i didn't get much improvement so i switched to paul kernel and changed modem too (jvk->jvt).
Still can't reach the dreamed 24-36h, i mean, i don't care about having 2 days of battery life, i would like to use the phone without having to charge it in the middle of the day.
btw nstools installed and set Deep Idle on, which seems to works just fine for me with the paul kernel.
(can't post outside link -.-)
nstools stats:
h*tp://i44.tinypic.com/6duvzb.png
does these stats means it's working?
i'll post also CPUspy stats:
h*tp://i43.tinypic.com/35052qf.png
is it everything ok here?
On standby there's no battery drain effect now, but when i'm using it, i get 1% down every 1-2 min.
What do you guys suggest? do i need to try other kernels/modems? shoud i try to flash again?
p.s. on 2.3.5 stock i used to have 24-36h but there's no way i'm going back to GB, i love ICS.

I used to have 24h of battery life, but I don't know what happened, after a week or so now my phone is draining 20% every hour, dead by noon...
Tried NStools with undervolt, and it didn't change anything.
It's now an useless piece of junk... this is retarded, either i will try reinstalling ICS or im going back to GB.

maybe your problem is caused by an app, or more than one, which are using push notification, you sould try uninstalling some...
Tried undervolt too, i got maybe an hour more.

Update: i just flashed again with RC3,1 and paul kernel. Situation seems a little better, gonna update again after few battery cycles.

What thing is in the battery status menu?
If it is media server: settings-->apps-->all--> Mediastorage-->force stop(dont wipe data)

sure! with the new paul kernel the battery life is better! amd now i'm trying the last glitch...my phone seems to work better...!i will hope to have also a good battery life without hard drain (with didle support maybe it's possible!)

actually, there was a lot of "Android OS" usage, maybe something went wrong from the beginning, the phone wasn't going to deep sleep state when put on stan-by and use more cpu than necessary when active, that must have been the main issue.
As i said, installed RC3.1 again this morning now everything is gooood
Lots of facebook, whatsapp, camera and 1 call, still have 67%. When put on standby battery almost doens't drop at all (checked on battery graph).
I think it's solved

I've the same problem. my battery life sucks...
Now my question. Where can I find/download the paul kernel? I#ll re-flash it too .
And my second question, do the "devil - der teufel" kernel do a great job too?

dunno about devil kernel, i read that for someone is even better than paul and it solves also "green screen" issue that appear when you lock the phone. I'm happy with this config so i won't touch it until RC4
I confirm that ,now, when my phone is in stand-by, battery usage is almost 0.
btw paul's kernel can be found here:

(sorry about the "*" in the url but it won't let me post link 'til i get 10 post -.-)
is also in the first post of the Team ICSSGS rom btw

I have flashed RC3.1 yesterday, it lasted for 8 hours. I was using it heavily to check all the features, syncing the contacts etc. I have drained the battery fully now. Will charge it upto 100% and see how long it last now with normal usage.

Battery Drain
hello everyone - I have been searching a lot abou this i9000 battery drain on ICS. I am using ICS and Devil karnel and battery lasts for around 11-12hrs. My usage is pretty normal. I dont use phone for most of the time but still it reaches to 12hrs mark. If I check battery stats then Android OS and Display (brightness is very low) are consuming most of the battery.
Please let me know if there are any ROM Tweeks or any other way to increase battery time. Or I will have to go back to GB because I hate charing battery two times a day.
Thank you.

[Q] Galaxy S Plus battery swelling?

Dear fellow enthusiasts,
since a couple of days, I'm experiencing sudden device crashes when I'm using it for network related activities, mostly over the 3G network (for example, I'm typing out a message on the Facebook app, and the phone goes into boot loop or simply "shuts down"). I had only recently upgraded to the 4th beta build for the Cyanogenmod 9, hosted here on XDA , so I suspected it would be related to this. However, upon reinstalling both the previous version and the new mod from absolute scratch, the issues remained the same.
I had noticed that after each crash, the battery charge displayed as very low (2-6%), whereas I'm certain the charge should be much higher. So I thought it might be some sort of corrupt battery-cache issue or something.
However, and here's my actual question, I just now noticed that my I9001 battery is slightly bulged, on both ends. This bulge starts just above the white printed SAMSUNG lettering, and it ends just bellow the QR code. I can't for the life of me remember if or not this is normal, so could someone please confirm this for me?
And while we're at it, could a faulty battery affect my performance as such (making my phone crash etc)?
Thank you very much in advance for any help or information anyone could give me.

I confirm, battery is slightly bulged in those places but it looks like a production "thing" to me (I hope I understood what you mean), no need to worry, I guess. Looks like corrupted battery stats, try to wipe it via recovery (phone fully charged, plugged in - then wipe battery stats). After that, i recommend one or two full battery discharge - charge cycles. I've noticed hovever, that after each full factory reset I have for about 20% better battery drain, than after flashing many ROMs, kernels and updates (cache and dalvik cache wipe only), my battery drain is getting pretty annoying. Try a full factory reset, if wiping battery stats didn't work.

Thanks a lot for the confirmation Jacol !
Anyone else who can confirm a bulging of the 1650mAh battery for the I9001? I'd like a large enough sample group if possible.

also happened to me
solved this problem by buying another battery...

Thanks Blumdum, do you mean you also had your phone crash on you?

yes
i charged the battery
after some time my phone turned off
i restarted it and i had only 2% battery left
then i took a look on the battery stats and there was a huge drop from like 95% to 2%

Thanks Blumdum, I've ordered a new battery, it should arrive within a couple of days, I'll confirm if this fixes the issue.

Same thing happened to me,i will order momax 1700mah

Hey people,
I received my new battery last night, I went for an Akku Powercell of 1800mAh. Charged overnight, been using it all day, no problems whatsoever to be found.
Thanks again for the assistance!

Swollen battery = defective!
I'm sorry but I've encountered this as well in the past. Normally working phone with sudden shut downs and huge drops in battery charge. It took me a long time to convince me that the battery was defective. So maybe this would save you guys some time in finding this out!

Hey, try to use cm10 for a few days, if the problem gone then your battery is alright, and please stop using beta roms, regret are so buggy and slow: )
Sent from my GT-I9000 using xda premium

In general healthy batteries DO NOT swell. Buy a new one before it explodes or starts leaking...

Hey all, just because people keep on posting, the battery was indeed defective, the roms were absolutely fine and the new battery is performing marvellously!
Thanks again for all the input !

I have the exact same problem with my sgs i9000-gt.
My phone turn off itself ( no restarts, its a complete shutdown ).
First, I thought i might be a problem of GB 2.3.6 rom i was using, so i updated to latest cm10 but the problem persists.
If you restart the phone after the shutdown than i shuts down within a minute again.
Also the battery drain is pretty fast. I notice the same bulges on the battery as reported in this post.
I did the battery calibration thing as some people suggested, but that does not solves the problem. However, it got rid of the fast changes in battery status which was happening before. Like when you restart after shutdown at 80% battery status, it will show like 2% battery left and after few minutes of charging it would boost back to 80-90%.
But still the battery drain is pretty fast. It discharges from 98% (i cannot get to 100% charge, 98% is highest) to 50 % within an hour, just idling.
And when i am around 40% or so and if i recieve some message and try to open a app it shuts down again.
I have ordered a new battery just in case. Will update here if that improves things for me. But i will still like advice on which is a more economical kernel and rom for i9000-gt? Some people suggested slim bean + semaphore on some forums but i would like to have some more concrete advice before i change more things without knowing the source of the problem. I would be grateful if someone can suggest what is best to use with some details( version, etc). Thanks for that in advance.
I thank you all (users + developers) for all the useful information provided on this forum, i learnt a lot although i still am not able to fix my problem . And I hope someone might come up with a concrete solution for this problem. If there is a solution which I might have missed, I thank you in advance again and hope you will be kind enough to point me in the right direction.
cheers
update: the phone stays alright if u dont do anything on it, but the moment you being doing something on it other than playing with system settings, like run some app, especially something that uses network / wifi, it shuts down. none of this happens though while its plugged in. it happens only when its on battery.

problems fixed so far after replacing the battery

I flashed back to stock samsung rom ( from the value pack) and the problem persisted.
today my new battery arrived and all the forementioned problem seems to be gone with the new battery, my phone seems to be working fine for last 5 hrs without any restarts or crazy battery drain. will test the same with custom roms again. As of now it only seems that problem was the battery.
Cheers.

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks

What about your connections? Do you have 3G/wifi enabled at all times?

calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now

Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal

Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone

Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher

Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

About 2 hours later that I fully charged, here are some ss
Just used whatsapp and opera in this time
I was thinking in change my kernel, currently I'm using semaphore 3.0 with CM10.2, is Latrop or Mackay better in battery life ?
I think its my last shot ... I'll provide a new battery next week, but i've heard some people with batt probs that even with new batt the problem persists :crying:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Using bout 2 days ... but i didnt knew about ' calibrate '. Good to know that
Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage
