[Q] Battery problem - Galaxy S II Q&A, Help & Troubleshooting

Hello guys i have a problem with my battery.It drains so fast and i dont know the reason.I noticed that chrome is using about 40-50% of the battery while my screen does use 36% and apps like facebook,youtube etc. about 2-3%.Whats going on?Can i fix this problem or i have to buy a new battery with higher mAh.I also found that calibrating my battery might solve the problem but havent tried it yet so i give this a try and let you know.Let me know what you think.

Depends on how long you've had the battery ?
P.S - You can't 'calibrate' a S2 battery. It's impossible. Ignore the crap on here/elsewhere saying you can.
Extra P.S - Which S2 variant are we talking about - I9100 ? (Ignore what I'd said about double posting, your other thread in General is sufficiently different, though you'd probably get more help if it was in Accessories).

I have the battery since i bought the s2 which means about 3 years.
About the calibration i dont know if it works or not i just said i found it as a solution on a search i had.
Yes its I9100.You are right about the double posting but i am new here and i dont know exactly in which thread to post so i did post on both.
Let me know what you think.I am using the phone too much if that helps and maybe the battery has come to an end and needs replacement.

Nah it's all good about the other thread, you're asking where to buy batteries so that's cool
3 yrs eh ? Getting anything beyond 18 mths is pretty good assuming you're charging it at least a little once per day (if you're doing a full charge/discharge you'd get less than that), and even if you're not doing that (say charging only every 2nd day), two years is pushing it.
You've done well to get 3 yrs out of it. I mean, you could get BetterBatteryStats & see if there's wakelocks/whatever causing drain that you might be able to reduce, but everything you've said points to a simple case of the battery being on the way out, so a replacement is probably the go.

Well then i feel better now I will get used to threads and all this stuff after being there for some time
Last year i think i over charged the battery because i used the phone too much and the battery was always drained.Sometimes twice a day!
I think needs replacement too.I will try betterbatterystats just to check where the massive drain comes from.
Anyway thanks for responding and helping me in a kind way greets!

No probs If you don't understand anything in the BBS logs, post your screenshots to the BBS thread, people who post there regularly should be able to help.

Android battery drain?

Hello there!
I'm experiencing heavy battery useage by Android OS, atleast thats what the battery use tells me. It uses over 40%!!
Anyone expierincing this aswell? Or anyone has an idea how to fix this?
Thanks in advance!

You're totally right, there is no topic at all regarding battery issue on SGS2 ...
Who is useless ?
Battery drain its a question of reading the varying fixes and or reasons why and trying them out .
The post regarding Android OS battery drain may help or not .

Yes, this phone has horrific battery drain. I recommend you take it out to the nearest field, strap it to a rocket, and shoot it into the stars as soon as possible.
Or, you can consider using the search button or follow the MANY links the nice gentleman posted above for you.

Lol maybe the battery will drain less in an area with very little gravity.
On a more serious note does anyone know of a list with apps that are safe
To freeze or even remove? I've been looking through the above posts for about an hour and can't find
Squat.
Edit : holy crap I need to open my eyes, its stickied at the top of the general section.

Yea I saw. See my edit. Feel silly now lol.
Just do a factory reset fixed all my problems and my phone came with KE7 installed I didn't upgrade to it.
Battery life went from 10 hours to a day and a half
after lot of tests, i discover that was the calendar sync. In idle mode my phone drain 5-7% per hours without 1% per hour.
After I uninstalled all the useless battery draining system apps, my system doesn't use alot.. like 2-5% , but my screen is getting 50-60% everytime!
I allready tryd different settings, but still, it attacks.
Do someone here have a friend with a SGS2 with good battery life !?
Try to change the battery for 1-2 days and see if its better or not, so we can know if its the battery thats need to be changed!!! report pls !

I doubt EVERYBODY that posts in these forums have a faulty battery. It MUST be software related. So many "faulty batteries" would be a great cause for concern.
from my understanding its 50% user and 50% the version of gingerbread were running.
Im coming from an atrix which has great battery life. A little bit of optimization which the great devs are doing is definitely helping.

[Q] Request: Bali 1.8.8 with -50 mv accross frequenzies

Hi there,
probably that request would make more sense in the developer forum but i didnt post enough yet
Actually i get insane battery batterylife with the bali 1.8.8 UV version, therefore i tried the non UV version with even more lowerd voltages via set cpu. it was stable but drained a lot faster. don´t know why.
so my request would be "pre-undervolted" bali kernels that might have even longer batteryliftime. Any hints on that? Someone who is able to compile something like this?
Best regards,
vibrantoparanto (from germany)
Hint' Bali X+Voltage control app= win !!!
Sent from my SGH-T959 using xda premium
^^ that is your answer....currently what im using
bali-x is what i used before - i lowered the voltages up to -150mv with some frequencies but it still gave me only about half the battery lifetime (less than 24 hours with moderate use) then i get with bali uv. What did you use to manually undervolt and how is your battery lifetime?

i hate to burst your bubble, but youre chasing a ghost. uv'ing will not produce very noticeable changes to your battery life, especially if were are talking baout different versions of the same kernel.
take a look at this: http://forum.xda-developers.com/showpost.php?p=21024393&postcount=8
Cannot agree with that. I tried *a lot* and flashed different roms and kernels for years now. With stock kernels i get up to two days standby with low/moderate use, with bali UV i get almost three days. I have no idead why, but at least the standby time differs dramatically between kernels. At least thats for sure - under load that might be another thing. But probably you´re right and its just a "good standby behaviour" which would hardly benefit from lowered voltages. Would be still interesting to try a hardcore UV kernel
TopShelf, it is funny that you posted that note/post b/c I was just getting ready to PM you that I put part of it in my guide like I mentioned a week or so ago and the apps too.
Take a look at the Guide and maybe you will find some answers to your questions.
If you want to UV to the max, then you will have to test that yourself b/c every Vibrant reacts differently to OC/UV. Step it down -25v each day (don't set on boot until you know they work) and see where it freezes. There are OC/UV examples in the guide but beware, they are both for MIUI kernels.
Is there probably any admin out there who understands what i talk about and can move that thread to the developer forum?
this thread belongs here, you posted in the right section. posting in development will not get you answers from developers, it will only get you yelled at by hall monitors.
it is a common misconception that "developers" ONLY visit the "development" section. this is far from the truth.
sorry to say, the reason you have not gotten answers isnt because you posted in the wrong section, but because requests like these are pretty much never honored. the reason is because if a developer decides to make a slight alteration to a ROM/kernel for a member, he will then get BOMBARDED by dozens of other members who have tiny little tweaks that they would like in their ROM/kernel
Still trying to bring back some life to my request with this argument: I just checked my girlfriends device (using zendroid 2.1.2 with bali 1.8.8uv) and couldnt believe it: 3 days and 14 hours since unplugged with 8% left. The battery is a stock 1500mHa. And as its my girlfriends phone its definity not "overtweaked and calibrated". Personally i care much more about standby time than super heavy usage (guess that should be fine then too).

Since you didn't like the answer you got, for clarification purposes you are basically asking for a dev to use their time for FREE an modified/debug/test a kernel with your requirements just for your own sake ?
i wanted to point out that this is a very interesting kernel with great battery lifetime. if you have a look at all the other threads of people desperatly trying to get 24h of battery then you probably wouldnt consider this request as "wasting free time of others for my own sake".

i can prove to you that UVing does not make that much of a difference. if youre willing to learn, try this little experiment:
-UV your phone using your current settings
-put your phone in airplane mode
-turn it off
-charge it to 100% while its off
-after it boots up, leave it in airplane mode and immediately lock the screen
-let your phone sit idle in airplane mode from full charge to death (record the time)
--------------
Once youve done this, repeat all of the above steps but with STOCK VOLTAGE. record the time.
now compare the two times. i would be willing to bet a large sum of money that it is not a notable difference, if any.
my point is instead of trying to convince yourself that your theory of UVing is correct, why not do a TRUE battery life test, and simply find out for yourself. you cannot run true battery tests while you are actually using your phone becuase phone usage is massively different on a day to day basis, even if you dont think it is, it is. there is background data, text messages/calls, notifications, etc. (which is why i said to put it in airplane mode, that way its just sitting there, with little to no variables)
i guarantee you that you are putting way too much thought into voltage settings. they do not help as much as people want them to. dont say im wrong until you actually try what i said above. although youre probably nto going to.

sorry, but this does not prove anything. what are you comparing it to? your phone? you cant compare her battery life to your own unless you guys have the same exact setup, same exact apps, and same exact usage habits, etc.
you are not going about this battery things the right way. you NEED to be willing to learn more instead of trying to come up with your own reasons in your own head as to why your battery gets a specific lifespan. If getting THAT MUCH more battery life was as easy as UVing your phone, dont you think the manufacturers would incorporate that and use that as a marketing strategy?? "New from Samsung, the Galaxy S III!!! This will revolutionize the mobile industry, curing the battery woes across that smartphone world...now with lower voltage for drastically improved battery life!! Pick yours up today!!"
It's not that easy, you need to read up on what affects battery life.
thank you for your thoughts topshelf, but as i posted earlier i am on that topic for years now and i really tested a lot. not as scientific as running phone on idle with different frequenzies but trust me: I know a whole lot about this topic. Also i share your thought that the voltage is not that important in the end. On the other hand i have to say you guys are quite ignorant about my observations i did earlier:
1. The bali-x kernel with manual undervolting provides (provable) worse battery lifetime than
2. the 1.8.8uv kernel.
Conclusion: As you say it is not that much about the voltage but about the way the kernels work as a whole. On the other hand it would be *very* interesting if the insane battery lifetime of bali uv could be even further improved. And no i wont put my phone to sleep for days in order to do scientific test (whoever is willing to i will donate - battery lifetime almost like astrology)
Last but not least: It is true that different roms provide significantly different battery lifetimes - for whatever reason. Some roms turn your phone into a handwarmer, others give you almost the standby times you were used from the non-smarthpones. And i think even the big companies have a hard time to write device specific code that is highly optimized - i mean you still get new devices with gingerbread instead of ics and so on. conclusion: on the software side *is* much room for improvement if it comes to battery lifetime on most devices.
just my 2 cents

Look at your post, you and "others" are asking for some one to do research and development on their free time and for free ? little selfish on you.
Look at all the kernels thread in the development section and read thru all the comments, I bet there is far more people whining and complaining about this and that, than providing actually constructive and monetary feedback to the developers.
Its not as easy as it seams, ecotox already tried this before with his ultra low power kernels and some reported great succes while others couldnt even boot, it goes down to the quality of the silicon on each particular phone. no dev has the time/money to develop such request considering all the different variables involved.
lastly if you are so fond on this idea, why dont you take the initiative and learn to compile and patch and make your own kernel ?

im not trying to pick on you, but this sarcastic response shows your overall attitude that jrafael is trying to make you realize. you want somebody to take time out of their day/night to do something for you...yet you arent even willing to let for phone sit for a day in order to learn a thing or two...letting your phone sit doesnt even take any effort, compiling a kernel takes a lot more effort than that
i hate to say it, but why should someone help you, if you dont want to help yourself.
thank you jrafael for the links - thats a great read.
@topshelf: still think you overreact here. For one who has developed it and has the workflow it is a matter of a few minutes - and no one is forced to do anything unless he thinks its might be worth it - maybe its inspiring? i am just asking. not everything idea must be done by the one who thinks about it. and the quote about battery life is true i would say - we are really lacking valueable info on battery drain with different setups.

Same phone, same hardware - opposite results, why!!??

I am trying to understand this phenomena.. I realize this is more of a philosophical topic than a technical topic, but its something I think about ever day when I read the forums and try to help people with stuff.
To start, my good friend, and my wife have rezounds. To be fair, my wife could care less about the ROM she is running, but, I like to keep her updated. My friend and I go back and forth about what rom is better, he likes Rrez rom, I like Cleanrom, but we flash back and forth.
Out of the 3 of us, We have never had any of the problems that I see other people having. Why?
We all (you guys too) have the same phones, we flash the same software, how is it that Joe gets 24 hours of battery life, flawlessly smooth performance, crystal clear reception.. while John gets an overheating battery, stuttering performance, unusable signal and 4 hours of battery life?
I continue to read posts from people complaining that this rom sucks or that rom sucks..
So.. is it the PERSON, the PHONE or...
maybe not all rezounds are the same inside, and maybe some software does not work with some versions of the phone. That seems pretty ridiculous though.
When I flash mine and my wife's phone, i usually "race" them to see who's is fastest (ya.. its stupid i know). But from the first power down, to wiping to flashing the rom. i press the buttons at the exact same time, and both phones complete the process at the exact same time, boot up in the exact same time..
you get the idea.
just to see if there are any differences, I did a clean flash of clean rom 4.1 on both phones, and let them sit with the screens on, full brightness for 1 hour. they BOTH drained to 83%.
These phones were purchased 3 months apart, and one from VZW and the other from Amazon.
my buddy has never had any of these problems either (his wife has a rezound, but she wont let him flash it)
none of us have had problems, why?
I am not trying to discount anyone's problems, obviously if your phone is overheating, its not something you are making up.. but why is it that YOUR phone heats up, yet mine doesn't
This is a real question, and I think it deserves some sort of analysis. A real answer could go a long way to helping people who are having problems others are not.
Case in point, people are complaining that the radios in the new leak suck. They are getting crappy reception and they regret updating.
i LOVE the new radios!!! i get AWESOME reception!!.
Right now im sitting at 17 hours with 30% left and I tethered my laptop at school for 3 hours while doing homework at school.
A few days ago, I let the battery die (didnt charge it overnight) and it charged over 60% in 30 min, it was awesome lol
60% in 30 minutes? on the new ICS firmware? it took me 1 hour and 20 minutes to go up from 14% to 70% today...

trust me, I was just as surprised as you, I was sitting in lecture and it shut off on me. I went to study and plugged it in with the HTC charger and the supplied cable (i love that cable) while I read over some material, 30 min later I unplugged it and it was at 62%, I almost fell over lol
im on 4.1 with stock kernel. I flash my phone so much that I dont have **** installed on it (battery saver wise or whatever). It just a normal phone. I dont OC it, I dont run apps that close programs..just stock build
I've wondered the same thing. I'm somewhere in the middle here. I have some heat problems (can't charge and use a lot of mobile network, heavy games push me to 120-ish), my battery life kinda sucks (it's great, as long as I don't use it... but I get like 2 hrs screen on time). Overall though, it's not a terrible situation, and I still dig the phone.
But stories of 24 hour battery life and never seeing temps above 90 sound like tall tales to me.
I think some of it is that we all have our own interpretation of "moderate" use. I'd imagine some people think two hours of screen time is moderate use (a few facebook checks, some phone calls, and some email over the course of a day). To me it's extremely light... I'm at an hour+ by 10AM most days, 2 by the end of work, then I run with gps, play a game or two in the evening, and you get the idea.
I can't speak for those who have radio/ reception problems... but I've become pretty convinced that the other two main "issues" are mostly due to perception.
I think some of this may be location... if you are in an area where reception is spotty, your phone works harder to gain a connection, gets hotter doing it and uses more battery power.
I went from last Thursday to Monday morning with zero WiFi and the phone was using more power than my normal use, but the connection was solid, speeds were solid as well. I normally use WiFi most of the day because if I am at home or at work, I have a good solid WiFi signal and the phone uses less power (for me at least). My test over the weekend was a good test for me showing that while 4G was solid, if I have WiFi available I save battery power using it.
In general, I have rarely had issues with any phone that I use. Never had to replace one or return it for defects or any other reason. I am good to my equipment though, my Dinc still looks brand new and I got it pre-launch.
It's about 20% phone problems and 80% problems with the people. A good majority of people who flash and then complain are those who don't know what the heck they're doing. In the case of the new firmware, many didn't follow the directions to a T. They got a bad flash or a bad download. Then there are those who flash a new ROM and don't take the time to read everything before doing so. These are the 80% that are essentially complete morons. They do idiotic things that just can't be explained. These are the types of people who should either not be flashing ROMs or who should be using iPhones. In my opinion, if you don't read everything and then complain about something not working correctly, it's your fault.
That being said, there are phones that just suck straight from the factory. Some people who really know what they're doing have these phones and get bad results when running the new firmware and different ROMs. There are plenty of these people on here that have these issues. I feel bad for these people. I certainly don't feel bad for the other 80% who go into a thread and complain that the ROM sucks or something when it's completely their fault.
EDIT: And yes, much of the battery drain and temp problems can be blamed on location for those who have phones that just can't seem to grab a 4g signal for too long. I live in an area where my 4g is solid 99% of the time, so I have no issues. I was in an area about 2 hours south of where I live the other day, though, that had crap 4g signal. My phone definitely drained pretty quickly that day and did get a bit hot.
These are all good points. and actually I never considered location before,
And i thin you are right on with the perception. There has to be a way to standardize some of the stuff to rule out perception. So when people say "man i get crappy battery" We can say "well did you run the (insert standardized battery test) test? what was the result?"
say the test was something like leaving the screen on for 2 hours, starting with a full charge and in airplane mode to rule out reception. Theoretically, all phones with the same ROM and kernel should drain the same amount ..
It is also common for people to see a new mod/rom etc.. and rush to try it out without doing any prep for how they will recover if it doesn't work, how to go back, ramifications of the changes they make... checking first to see if others had problems with it first... etc.

lol, Rom devs should put in a system where new people are required to read the entire "read me" file along with flash instructions, and then answer a 20 question test and score at least 90% on it. Then, and ONLY then do they get the DL link After 10 or so times of doing this, the requirement would be lifted.
this idea makes me laugh..

Hahaha that's actually a really good idea lol I would change it to 95% or higher, though.
i know for a fact i'm not blaming it on the rom, or not reading right, or not flashing the firmware right.
i did everything right, and i'm 150% positive of that. thing is, when a rom runs great for the first 4 days or so, then out of nowehre i'm going from 18 hours of battery to 5 hours of battery, clearly there's an issue SOMEWHERE.
i'd love to blame it on verizon trying to push 4g here, but i run on wifi most of the time, so i don't think that's it.

i know for a fact i'm not blaming it on the rom, or not reading right, or not flashing the firmware right.
i did everything right, and i'm 150% positive of that. thing is, when a rom runs great for the first 4 days or so, then out of nowehre i'm going from 18 hours of battery to 5 hours of battery, clearly there's an issue SOMEWHERE.

I've read your posts in the threads. I meant to put that in my post that you weren't one of the 80% I was talking about. I think yours is a case of the other 20%. Or it could be something to do with the firmware going all bonkers on you.

by the way, your sig is aweomse.
And yes, **** does happen sometime. but its usually clear from the way the post is written that the person was clueless.
posts usually start like this
"I tried searching but didnt find the answer...."
and then they ask how to flash the rom, or something else that has been covered 1000 times (you have to UPGRADE TO NEW LEAK FIRST)
yeah man, i really hope it's not! everything went smoothly...well, almost smoothly, i was one of the few where the phone froze on the white HTC screeen, and i did a batt pull, and when it rebooted, it began the second step of installation..but i have yet to have any force closes or anything. maybe i'm subconsciously using my phone more? i really don't think so. screen on time should pretty much help judge that, and it's not showing anything out of the ordinary...and better battery stats isn't showing any crazy up time..my awake time is like 39%..i mean, maybe the 4g issue is it? idk..like i said, i run wifi often, so that means mobile networks OFF...
then again, i'm running just 3g tonight ot see if 4g comes on again, and 3g keeps turning off, and switching to 1x..like, constantly...so they MUST still be doing something down here..

I got stuck also. Scared the hell out of me. But mine seems to have gone through the RUU perfectly and I've been getting insane battery life lately. Like at least a day every cycle on a stock 3.8v. It really could be a case of bad timing with the new firmware and Vzw updating 4g in your area that could be killing your battery. I hope you figure it out soon, though. That would be driving me insane.
you're running the RUU? i'm running joel's Bamf. works pretty well; i like ICS better, in general

Sorry, I meant I ran the leaked RUU and firmware and that's where I got stuck for a minute. But I'm on BAMF right now. I always run the latest BAMF.

Battery life - stock gingerbread

Anyones gs2 seem to drain battery quite quick? Ive had a few android phones and the gs2 battery seems to fly down.. Im a heavy user most days like get up in morning facebook and apps all day long.. Strange thing is though i get about 5 mins worth of usage before it drops the first line off the battery.. I get max of about 5 hours of heavy use before i need to recharge.. This normal for gs2?

As posted search but start your search with Better Battery Stats .

I am using the stock ROM and not having any issues with the battery lasting less than a day. I had to make a few changes to the settings, but once tweaked I am really happy with it.
Normal for me... a day and a half of light to moderate use. Plenty of syncing every hour, lots of Wifi and GPS, never switch any radios off, lots of FM Radio, auto brightness.... blah blah.
KL1 + LPR baseband, stock rooted, bloat removed. No silly apps, no silly task killers, no battery defenders/benders/superchargers/tweaks or other nefarious idiocy
Im fully aware on how to search.. Wasnt asking for tips on battery life just generaly wondering if my stats was worse then the majority of users on here..
This forum is getting worse for big heads..
Anyways thanks for the input.. Will have to do some "searching" on how to optimise my battery.

And far far worse for users that point blank refuse to search and only want to ask the same question day after day .
This is a developers forum not some hand holding fix my phone forum .

Actually having just found the location.. This is Q+A right? Where am i supposed to ask a question?
For others ive attatched my battery stats for today.. Seems a little quick.. I also did a few tweaks to setting as suggested above. Hasnt made a difference.

You're phone is active most the time, rarely sleeps. If you compare with mine above, you notice that the activity is in short infrequent bursts. The screen being on takes a huge amount of power - it's a big screen. And OLED.
I would say considering the sheer amount of use you give it, it's doing rather well... NO comparable smartphone (except the Razr Maxx) will give you much different. It can't.
By the way. not sure why the battery falls off a cliff from around 30% in your pic - scary!
1st, the post was apparently originally posted in a different location, then got moved to the Q&A section by a moderator.
2nd, your screenshot has what looks like a LOT of screen on time. What are your display stats for screen on time? (hh:mm:ss) From my estimation just looking at the bar graph, it looks like you have over half, and nearly 2/3, if not 3/4 of your overall battery time with the screen on, and the phone being "awake". With your overall battery time being 7:16:39, from your screenshot, that's about 3.5 to 4 hours of screen on time? If you are constantly using the phone, or keeping the screen on, it logically follows that the battery will drain.
3rd, JJEgan's point was this: This entire forum is meant for developers. (the name of it is "XDA Developers", after all) Yes, there is a Q&A forum, but more and more, users who are not developers are posting all over the boards stuff like "why is my phone doing blah blah blah" on commonly answered questions, (which is a clear indication that they didn't look or search very hard for the answer, even if they say they did) or, even more offensive in my opinion, "upload XXXX file for me" without so much as a please.
Non-developers are welcome, obviously - heck, anyone can join. But more and more people completely disregard the forum rules, which are plainly posted for everyone to read at the very top of each forum section.
Ahh ok.. Sorry.
I joine the forum as i have a genuine interest in all things phones wise.. Wether that be cooking roms, mods tweaks etc etc.. I dont come on here on the sole basis of asking questions.. Every now and again somethings niggle me about my device so the best place for info surely is xda developers. Though i only use the app at the minuite to view posts i did'nt actually know where the search link was. Though now i do i will use it...
Anyways:
Yea i did notice that big drop on the end of the battery stats.. Thats happened a few times ive noticed.
Dont think ive seen anyone elses screenshots look like that.. Could it be a sign of a dying battery? Or just wrong stats.
Ive read that the battery stats clearing does nothing as the stats it shows is whats using the power n not actual battery level.
My phones only about 5 months old too so everything in it should be in as new condition.
Strange..

My stats for today are what i expect really.. Did an hour of gaming.. Ish..
Screen times on and gaming time are attatched other uses are android os and 5 mins of draw something lol.. Addictive.. Might actually uninstall it so i put my phone down once in a while

Almost 4 hours of screen on is about average, actually. And I can't tell; looks like you still have about 20% or so left on battery in those shots?
I had round about 20% yea. Heavy gaming today though.. No jobs to do
As long as its not too bad i can manage. But thanks alot for your input..
Really appreciated.
Sorry for the confusion mods as to where this was posted.. I will climb under my rock untill i manage to blow something up inside my device messing with it lol.
Love the work you guys put in.. Had many roms etc from these forums. So thanks for that.

battery problems

from past week my phone is discharging very quickly and I changed different roms but no use and my battery stats is proper and I think my battery life has gone .....and should I replace new battery ? if so which battery fits properly .....as I stay in India no vibrant here .......but i9000 is there.........
If calibrating doesn't work then your battery could be bad. Other than vibrant the i9000 and topic touch 4g batteries work with the vibrant. Try ebay or amazon for cheap batteries.
Have you read this nifty little thread right here?
http://forum.xda-developers.com/showthread.php?t=1389069
Also, what rom are you running? I'm asking because if its anything JB, I wouldn't expect much in terms of battery life.
Also, what kind of usage does your phone get on a daily basis? Are you a light or a heavy user?
What kernel are you running? Which i/o scheduler and Governor are you running with?
OC? UV? The more info the better my friend ^^
There's all that too, much more helpful then my response. I just figured all the basics where tried already. I've had batteries mess up on me before. My original g1 battery got so bad that when I checked it, it was bloated.

Aha, both are helpful ^^ It's all pieces of the puzzle in my eyes lol
But if we can get a good idea of what the root of the problem is, we may be able to fix it without him having to buy a battery :]
I remember when I used to get 7 hours at best outta my phone, and I thought that was normal...but then I learned a few tricks, and
now I never get below an easy 24 hours on my phone, no matter what rom I am running. ^^
after calibrating it is working fine ..............thnx guys saved me from buying new battery
