Hello,
I recently got my nexus, and rooted only two days after receiving it. I installed cyanogen's latest. I am getting low battery; in only 5 or so minutes, the percentage goes down by at least 2 percent (while using). I looked to see what may have been draining the battery, and found that the display alone was using 62% to 75% of my battery. I tried undervolting, but the display seemed to still be in the same draining range...
Is this a hardware related problem, or is this a common nexus thing?

same here, really starting to piss me off when i see people talking about 70% battery at the end of the day while my phone dies in 6 hours
Cyan?
Woah, I think this might actually be cyan's Rom.
I flash enomther's rom and i got display percentage at around 15-16% ...
I think cyan will look into this soon enough...
But for now... I guess I'm gonna wipe... :/ and stick to enom's or some other ROM...

C´mon....see my signature!
More than 10h now, Wifi on all the time -> 70% battery
This is not that bad

I think the problem is only with a few people, but I know others are experiencing this. This might be something with the "latest" nexi. But idk, it's a mutual issue, a fix should be coming
Probably you are right...
But, I would like to know, what settings peolple use: like updating wheater every hour, emails, widgets,..ham many apps are running and so on, ... perhaps connected to...sometimes people dont even know that
Edit: I got my Nex in january.
The change in the display usage percentage is just due to the way the powermanager works. Its not using more battery, its just displaying how much power it is using more accurately.
have the same problem.
100% airplane mode ON no WIFI, in 5 hours 72% battery remains . (PHONE IDLE took most of this - my G1 could go 1 month with this settings)
IN 12 hours in was 6% and with LOW use of my N1.
Yesterday I removed numbers in my battery and it was a litle better, not much but a little. (about 8% better)
I had 5.0.5.1, 2 and 3 and everyone had the same problem!
CM please take a look at this. What do you need any LOG info or something!
Have you tried wiping battery stats, then charging to 100% with it off, then booting into recovery and wiping battery stats again, then charging to 100%? The few times I've had battery issues that's taken care of it for me.
I flashed cyan again with a wipe (again), but got the same thing.
On enom's rom, I get beastly battery. I think we just have to wait for a fix for the people who are affected.

Do you need root to wipe battery stats? how do you do it?
Well I did the wipe battery about 3 times and in OS it was already green light 93% full.
I WIPED and put the power in on NON POWERED PHONE. It took 1 hour more to come to the green light . than I wiped again and went to boot up.
at 11PM i had 100% battery went into airplane mode wifi OFF.
And i did one other thing. Some of you had the battery drain issue with trackball wake. So I disable it.
7 hours of this and I got 97% - beautiful
before that I had 72% so there is a difference.
Now I have to see if the wakeup trackball is the cause of this or the wiping the battery stats.
Will eliminate one and other and keep you posted
I took my phone off the charger at 4:30am and the next day at 5:30 am i had 12% battery left. i used my phone a total of 3 times. most of the time it was on standby. i have setcpu with my phone UV and UC to try to save battery with profiles set up. in battery information 85% of the phones battery went to cell standby. Any suggestions on how to improve this?
Try wakeup trackball OFF in spare parts and battery % OFF in upper taskbar.
I have now from 100% to 59% in 7 hours. wifi ON all the time.
I have tried to wipe battery settings and charge fully with the phone off, but after the full procedure, I still get the same end result. I attached a picture of my battery usage.
Im pretty sure i saw a post online about the newer nexus's that were released having a better display. If this is true then wouldn't the phone's hardware alone be using more battery?
I can confirm I am having the same problem. I wasn't sure until I checked battery usage overnight. It used to be that with my phone on airplane mode I would use about 2% while I slept. Now, it's 9 or 10% with "Phone Idle" taking the lion's share of it.
I have tried deleting batterystats.bin after a full charge; powering off (while on charger); charging up to full again, but this has not solved the problem.
A few notes:
When the phone is idle (but not in airplane mode) it uses about 1.5% per hour (compared to about 1.1% in airplane mode)
I am using setcpu profiles to keep cpu usage right down when idle
Around the same time I upgraded to 5.0.5.3 I also started using the himem version of fastboot. And yes, if you suspect I don't know what I'm talking about here, you are quite right
For my next trick, I will try resetting battery statistics via recovery. What fun!
I've kept the cyan rom, and changed some settings to increase battery life. I turned off the battery percentage icon, and turned off the trackball to wake. I still got that the display was using a lot, but the battery still lasted pretty good. I guess there isn't too big of a problem on my side. It probably is the "newer displays" on the "newer" nexi. Maybe there really isnt a big problem
I changed now from CM to Enomther's TheOfficial Nexus1 1.8.1 and battery now works great.
I unplugged the charger at 12.00 am at midnight and with quite good use, not extremely havey but a good use I had 30% battery left at 20:00 (08:00PM) that day.
I lost only 2% from midnight to 7:00AM in my airplane mode and with Gmail check 10 min of phone calls wifi ON all the time checking web pages and showing off my live wallpapper at my work I had at noon (12.00PM) 70% battery left!
I LIKE IT!
now I'm thinking to push Kernel - .32 & .33 to see if there is any change with my battery
http://forum.xda-developers.com/showthread.php?t=653598
After resetting battery stats in recovery, I still lost about 10% overnight while on airplane mode.
For my next trick, I'll use a task killer like "Process Manager"* to keep everything unnecessary switched off overnight. Maybe I'll be able to narrow it down to an application if it's not something integral to the actual ROM.
*Yes, I know it will use up the battery too
I recently installed Serendipity and made sure the battery was at 100% while doing so (and deleted the battery file). I'm waiting for the battery to drain before I plug it in. Am i supposed to let it charge all the way again? Also, is it safe to reboot the phone while it is draining the first time? I want to install something using clockwork.
I'm being careful about this because cognition would report 14% battery life after 33 minutes of display usage and display eating up 96% of my battery....

There's a complete thread on this, I suggest you look it up.
After you reset your battery stats, it is suggested to do a few full battery circle (use til dead, full charge, rince and repeat). You should be fine after 2-3 circles.
Note tho that it will not improve your battery life. All it does is a attempt to tell your phone what % your battery life is exactly.
For your fast drain, I don't think it has anything to do with your battery calibration or your ROM. It's most likely a app (or a few) that are draining alot of juice or that are running w/o realy being needed. (Check your running services.. make sure you know which one to stop and not to***)
Also using a app/widget like advanced task killer can help your battery life as it will stop every app running with a simple touch. I suggest doing it anything you're not using your phone.
One last thing, display eating 96% of your battery is normal.. it's not telling you it's using 96% of your battery. It's telling you that during the time your phone as been unplugged, your display use was your main action.. probably cause you didn't make many calls or anything else.. Display is just about everything you do with your phone so it will always have some high numbers like that.

Yeah, I've seen the thread before but forgot about it. Thanks for reminding me. And my point about the display was that it was on for such a short amount of time, yet still killing my battery.
I am now down to 30% or so after 3 hours or more of display time after calibration & rom switch- and I was streaming music through WiFi and using Bluetooth headphones. So it it seems like it made a huge difference =D
Thanks
I'm having like 13hours to 14hours of battery life..Running stock ota 2.3.3..is it normal for such a battery life?(when my phone is fully charged right after I plugged out the charger,my battery drop to 94% to 96%is it normal too?kindly advice..thanks..

My battery indicator also drops from 100% to 96% a few seconds after i take out the charger. But after 2 days i stille have about 15% battery left.

My battery life increased after upgrading to gingerbread. I can usually go through the day (15 hours) with 3g always on, twitter and fb sync on, with light gaming and surfing of the web, 75% brightness.
My record was 2 days 9 hours with 0% brightness, no 3g, only wifi, no gaming, twitter and fb sync on.
For your percentage problem, you can try draining your battery, then when the phone shuts down, hold the power button to switch it on again. Start up an intensive app like a game to further drain the power. Do this until the phone does not start up (no bootscreen), then plug into the charger and charge overnight. DO NOT turn the phone on during the charge. When you turn on your phone after the overnight charge, it should read 100%
I am not too sure what triggers this, but its likely due to battery memory or something, although this should not be happening for lithium batteries. Maybe its a software fault. Do this every month or so to hit that 100% indicator. It is not advisable to do this all the time as draining the battery completely MAY damage the battery over time. Cheers!
How did you manage to get pass 2days of usage?

Hey,
I'm also having the same issue. Off the charger, BANG! 96% or so, sometimes more. My phone will be at 90% after like 3 texts. Its only had 5 charges mind you, I know there's a "conditioning" time but still, is this normal? I can almost say a text is a percent...my 3gs had more batt life after 1yr... now that's saying something...haha
I can almost watch it drain with the screen on...like 60 secs is a percent or 2...not cool...
Maybe I can do the "Desire Battery Calibration" procedure after a few more full charges...might make a diff...what do you guys think? I may be jumping the gun here...
Thanks in advance.
I remember someone said modern phones are designed not to keep on charging after reaching 100% and resume only after dropping to certain level, maybe 9x%. That could be the reason why I see different percentage left every day I unplug the phone in the morning. But my last Hero always show 100%.

That sounds right, because it drops from 100% to 96% after a few seconds, and its direct from 100 to 96.
But if you put the charger back it taks a couple of minuts to get from 96% to 99% and about 10 minuts to go from 99% to 100%
As far as i have noticed, this was the issue with X100 too after 2.1 update-
Once connected to the wall socket, the phone charges to 100% and starts dropping.
it does not charge again unless you reconnect the charger.
till the time it is connected, it will display as 100% but once you remove it drops to how much ever time has been spent since it reached 100%.
why that happens, i really don't know.
Ideally the phone should continue charging if the level is below 100. anyways....
about the battery backup, i think 13-15 hours is quite good for a phone with this display and capabilities.
with 3g, a little gaming, surfing, chatting etc. this should really do.
in fact, post the 2.3.3 update, the battery life has definitely increased.

So you think that having a 13hrs ++ battery life is good enough?More advice please..thanks..

I am on a VzW Inc2 w/ Froyo so not sure how applicable any of this is for you guys...but anyway....
My battery life is fantastic. I too see the 100% down to whatever after unplugging - I am pretty sure this is like others have said; once it reaches 100% during charging it stops charging and does not start again until you unplug and it re-plug it in. I know in my case charging from dead to 100% only takes like 3 or 4 hours. So if you are plugging your phone in when you go to bed it is probably hitting 100% after 3-4 hours and then the rest of the night it is draining down...
I have found JuiceDefender Ultimate and JuicePlotter to be huge helps to me in decreasing battery drain (JD) and understanding what uses the battery (JP).
Also just going into settings, About Phone, Battery, Battery use - this helps understand what is using it.
*Note: JuiceDefender Ultimate can create more problems than good if you are not willing to take the time to learn/set it up.
Prior to using JD and JP I would generally make it through the day, sometimes have a bit of power left over. After using these I always make it through the day, and sometimes through 2 days.
But let's not kid anyone - what JD does you CAN do manually...but more than likely wont or will forget. So for anyone that doesnt want to use JD, do you leave your WiFi on all the time, or do you switch it on/off? Leaving it on all the time drains battery. When WiFi is available, do you use it? I have found WiFi on this phone to use a lot less battery than 3G.
Probably my favorite function of JD I have it disable 3G and WiFi when the screen is off (for getting emails, updates, etc... you can set a schedule where it turns it back on during intervals or whatever).
Also I like the WiFi Location setting - you can teach it where you use WiFi and it will automatically turn WiFi on/off based on your location.
Anyway - my guess is if you are having low battery life, either you are using the device a lot more than you think (voice calls use a lot of battery), you have things syncing too often, or you are leaving radios/etc... on all the time that do not need to be on.
I tried to take the charger out at the same time the battery was on 100% and the LCD light went green.
Then the battery stayed at 100% for about 11 minuts and then went down to 99%.
After 3 1/2 houres the battery is at 95%!!!!!!!!
Bagground Data is enabled.
3G is active.
I have mail check every 15 minuts.
Screen brightnes at 40%
Weather update every 1 houre.
I don't use Facebook, Twitter, Stcoks and News.
I don't understand the battery in my IncS...
You guys know that these batteries don't have memory right? So when you charge doesn't matter, your phone just thinks there is that percentage of battery, do a full drain once and then it should back on track. Also, these batteries never get charged to 100%, its a safety precaution or something of that sort. They hover around 94-96% which is why the phone drops down to that area in what seems like a short amount of time. The fact that the phone says 100% when you unplug it is for effect. I used to always think I had battery problems, just stop being so worried about the battery and you'll notice an improvement. Hope this helped.

Also draining them completely flat, as in device won't power on, is the worst thing you can do to them
It sort of kills off a little of the capacity, every time you do it
So to the bloke that recommended it, no it does more damage than good

I'm finding turning to GSM only helps massively. I mean, so it should but I was hoping I didn't have to do this all the time, like I had to with my 3GS... And its a pain in the butt having to change it.
Still cant find a widget that will do it for me...not mobile data, ACTUAL WCDMA-GSM and back...
On the side, if anyone knows of one, please tell! haha

I tell you is true, and i don't understand i either!!!
Most of the 17 houres the phone was only in standby and i only read mail twice.
I guess its just a fantastic ROM that Mike1986 has made with no Sense ;-)
I can get a day and a half out of my IncS with heavy use on a pretty regular basis. Set brightness to automatic, switch off unnecessary auto updates, GPS, bluetooth, and keep volume down or off in games. My screen timeout is 1 min (reduce for longer battery life), and I have always on internet switched off. I generally leave my Wi-Fi on a lot by mistake but don't find this to affect things too much really.
You will get 96% a lot after a charge as it is bad for your battery to stay plugged in when it's fully charged, so the s/w on HTC phone switch the charge off for a little while so it runs down a little and back up again. I had Hero before and that did this as well.
juice defender ultimate is excellent in my experience.
i had it set to switch on data every 5mins for 15secs to receive notifications and do updates (i have quite lot syncing - twitter, fb, sky news widgets x2, weather) and i would sometimes have gotten 30 hours out of the phone (ie. i wouldnt have charged it 2 nights in a row sometimes), but always easily 1 full day.
im getting sick of having to use JD though, because i figured something HAD to be wrong as my battery would drain in maybe 5-8 hours without JD which I just dont think is good enough and so could not be how its meant to be.
i then read about some people having problems with cyanogen rom battery drain, and that if you switch off android market notifications, it solves it.
so i tried it, charged my phone to 99% again and im now at 82% after 5 hours 10mins, which means if i keep using the phone at this rate, ill make it 25 hours - which is more than good enough for me. (~and i still have all the same stuff syncing as before, except market notifications~)
also i have wifi set to never sleep, so its always on. (its my ideal that everything that you buy the phone for should be able to be kept on 24/7, eg data, gps etc always on - so i keep them like that. bluetooth i dont use though - if i can make it through the day on a charge with decent use, im happy)
try it.
im calling BS on jkolner btw - pics or it didnt happen
Hi All,
I'm a new registered user, so I can't put this in the developer forum yet.
I noticed a problem where I was losing battery power quickly, so I foudn a posting that said to do a "super" wipe. This was to one click recovery to stock, root, bootstrap, then boot into recovery to wipe cache, data, dalvik, format /system, wipe cache, data, install theory ROM 1.7. after clearing dalvik the second time, I threw in a "clear battery stats" for good measure.
What I noticed was this: prior to attempting any of this, the phone reported to be 96% to capacity and said it was "full" so it wouldn't charge any longer. After doing the sequence above, upon initial boot up, the battery was now reporting 88% and was charging again.
It would seem like the mechanism for reporting the battery usage is flawed in some way.
I am running a few days of testing but the calibration methods are to drain fully, and charge (while device is off) to 100%, unplug and before turning on, charge additional. Before my full charge read 95%, on 1.7. I did the above and now it read 100%.
From the beginning, here's how my battery life was:
Day one: full drain with performance mode, I received 8-9 hours. Used maybe 60 mins of voice, email sync w gmail and touchdown, sent about 100-150 texts. Watched 2 episodes of the community streaming from zumocast on 4g radio all day, used Pandora a few times.
Night one: night time saver mode, this is where I discovered my full charge was only 95. My night time mode activates at 10pm, my "full charge" completed at 7pm, used Pandora
On the ride to the gym, had minimal texts, email sync, twenty min phone call, 4g radio on. Went to bed at 10pm left phone idle, no charge. Woke up at 630am night time saver ends at 5am, device reported almost 12 hrs idle time, 40% battery left. Pandora to work, 4g only, synced mail, browsed YouTube, Facebook, no calls. phone full drained around 1140am. So almost 16-17 hrs on one charge, but the high light was 5 hrs from 40% battery... Last to note, I never turned off blue tooth.
Currently, after full charge 100%(not like previous 95) I'm at 1hr26 mins and at 85% bat...same usage, same battery mode
Ill get further results soon.
Update: now at 55%, 3:55hrs on track for about 8-9hrs ... Not using app killers to add or any battery apps. Problem seems sporadic but I'm going to try to run full battery to full drain on performance mode to optimize..in my past experience Droid 1 and Droid x, over time the battery adapts or the phone adapts to the battery usage ... Could be a myth or fantasy ...

Thanks a bunch for the info. I am in the process of doing the full drain right now. Hopefully, it will show some results.

Our phones read fully-charged at 95 percent, but if you keep it plugged in it will get to 100 - it just takes a good while.
There's a trick to that. Yank the back back cover, pull the battery, and unplug the phone. Plug the phone back in and wait for the "missing battery" icon to show, then slide the battery back in. It will initially read 5%- wait for it to charge to full, which should take 10-15 min. Repeat this process until the status reads 100% charged within a few seconds of putting the battery back in. Reboot into CWM and wipe the battery stats (or use the battery calibration app that's on the marketplace, if you don't use CWM) and you should be seeing a batter that's not only noticably more accurate in its charge level, but also charges more completely, resulting in somewhat better longevity.
You want to drain it fully and let it charge back up fully at least once after this process for best results.

This is a good trick, one I was taught by juhde. I used it on my x2 to great results.
However, I can't get it to read on my bionic. I get the '?' but nothing after I reinsert the battery.

I find it only works when I unplug it and plug it back in just before inserting the battery. It sometimes also helps to hold down the power button for a few seconds with both the battery and charger out in between 'bumps'.
my fix
I have flashed every update since the first post and had battery issues starting around 1.5. After reading through the dev thread a bunch it seemed as the when performing wipes, they did not come out "clean" after one wipe. So I started at one wipe of each (factory reset, system, cache and dalvik) and the problem persisted. I then did 2 wipes of each, then 3 and 4. after 4 wipes of each all my issues had been resolved. not sure if it will work for everyone but it was the turning point for my device and might be a good starting point for anyone who is as annoyed as i was. good luck!!!!
Update:
Was able to repeat 17 hrs with custom settings: data off @30 min peak/off peak. Blue tooth was on the entire time, cell idle and Bluetooth were 30% consumption each.
Right now I'm in full performance on track to do 9.5 hrs. I've been playing Pandora for an hour every other hour, and did not kill its process.
I think the most practical usage is to cut data when not used for 30 min, I couldn't imagine anyone on their phone doing multiple things for 8+ hrs STRAIGHT. I'm running unleashed 1.7, no radio problems and no slow downs.

My brother has been getting twice the battery life that I am getting. The only difference is I have rom installed, and he just debloated. I have a switch out extended battery coming from Verizon and if that doesn't work I may just drop back to stock debloated.

I'm at 10hrs 11 min running performance mode, Bluetooth had been on all day. Cell idle 32%, blue tooth 30%, phone idle 25%, display 7% consumption. No data sync interrupts.

And your battery is drained? Or at a certain percentage?

I think I have a faulty battery, I can't last 5 hours on a battery anymore. I'm going to go to VZW and see if I can pickup a spare and test that one.
This rom has absolutely nothing going for it. v1.7 and $6 will get you a cup of coffee from Starbucks. I have never flashed to stock as quickly as I did with this rom, since my first smart phone. Is this guy/team the only Dev with a Bionic??
Downloading/flashing on the fly (streamlined) is great however, what are we going to flash folks? 1.8??
Yes I know theory is only playing the hand he was delt but its clearly time to fold.
This makes me nervous.
For the issue regarding battery life..flash back to stock. Wait for the next developer.

Yeah? And what was the issue you had? ANY ROM you flash will nuke the battery stats and need to be recalibrated. Simple as that.

Sorry, yes it was at 5% when posted that, and that was right before my car ride with Pandora playing through Bluetooth.
The end time was 10hrs 35mins.
Since then, I have done a 4x complete wipe, cleared previous traces of unthrottle and flashed 1.7 again, disabled automatic restore apps while synching with google. I used the battery calibration app from the market this morning and have set custom battery management to turn data off every 15 mins of non use. This is practical since the power boost script shortens the time to speed up, so data on/off shouldn't affect performance. I'll update at the end of the work day. Currently at:
85%
1Hr 21mins
Maps 43% consumption (I'm adding GPS on all day in addition to blue tooth all day)
Cell idle 19%
Blue tooth 18%
Phone idle 14%

I just want to add, I'm absolutely loving this ROM. I would advise to check your steps if you are experiencing problems, and as always, keep in mind that its an ongoing development.

By your justification you are not getting normal/average battery life.
You are disabling data and your cellphone when not in use just to get close to average.
My battery drain has been pretty bad.
I have done all required steps (multiple times) but it still seems like the phone is just flushing the battery out of it.
The best life i have gotten is when (the other day) I was working from home and completely forgot about my phone.
I left it unplugged and after about 8 hours (of literally ZERO use no WIFI) the battery was at around 36%
Its like its pumping it out at full blast no matter what.
Note: I have all powerboost mods installed.
I just flashed back to stock, have the same apps and still getting the same battery life. I am actually getting more network disconnects for some reason, however common sense says that has nothing to do with stock rom or DT rom. Its a driver issue that will be getting resolved in Nov (hopefully) . Flashing back to my sexy DT rom tonight, with a full wipe.

I don't really understand what people are trying to solve.
Your problem is you left your phone on performance mode and it drained your battery. That's like leaving you car lights on and expecting it not to drain the battery. I'm exhibiting extreme heavy usage vs normal practical usage and how the ROM does *not* affect it negatively relative to your daily usage of the phone.
In my normal day, I would not have bluetooth running all day, which from my above data consistently drains 30% of the battery. Bluetooth is only used when I'm in my car which it connects to the car audio for phone and music. In my normal work day, I would not have GPS running all day, which from my recent post is draining 43% of the battery. In a normal week, I would only need to use GPS to find a unique restaurant that maybe I haven't been to or in an area I am not familiar. The main point for the contribution in this "battery investigation" is that I am not experiencing any radio loss, connection failure, or system lag by having Data shut off.
I really do not see the occassion that anyone would ever use their phone heavily for 20+ hours straight. Or even more than a movie's length straight. I could think of possible arguement points such as hiking and needing it to last for saftey/emergencies -- but why would you have it full blast on performance? Long car rides -- but if you are doing an 8+ hour drive, don't you plan on having a car charger? I just don't get what people's frustrations are. I do understand the problem that people's battery tick abnormally which is a fault of either the device, a defective battery, or lack of following directions when using the ROM. Again, the ROM is a development, and no one is forcing you to use it. It is actually quite nice to test, run into a problem, report it and have it fixed within days/weeks instead of months or never like the stock.
I guess I've rambled into a rant, but I'm merely providing my own experience in details so that people have a general feel of how the battery is and if my usage is similar to theirs.
I'm not claiming to have average/above average battery life, I'm justifying that this has not affected my daily use of the phone for everything that I use it for (being connected to work, being socially connected, and games/movies/music).
Hello, it's me again with problems. I have an extremely battery drain, even Juice Deffender can't handle on this. When I put the phone on charger, when he turns off after 0 % battery status, indicator shows me 50 % min after only few seconds on charger, and it's fully charged for half an hour maybe. When I turn on 3g and connect to Net, from 100 % to 0% is ONLY 15 min ?!?! I have cm-7-20120812-NIGHTLY-cooper ROM, but when I had offical 2.3.6, it was the same problem. Can I check some-how what is the problem- software, calibration or battery? I did a few calibration without any success. I'm really sorry on my very bad English. I will be grateful if anybody can redirect me on the right topic. Thanks in advance
3G eats a huge battery. I would not expect anything nice from it. But seems that your problem is a bit more problematic. How long do you have your phone?
Make sure you are charging your phone until its actually full not just when it says 100% look here for more details:

Did you try wiping battery stats in CWM or recalibrating it?
I've tried wipe stats with Battery Calibration, and with CWM wipe battery stats. I've tried different ROMs, DroidACE, official 2.3.6, cooper nightly ROMs, and all of them have same problem. I've noticed that the battery is a little thicker in the middle, before it was flat, and now is a little convex in the middle. I've tried also discharging and charging for a 5+ hours, didn't help me. literally be emptied by 20 min of Use

Sheesh guys. Battery Calibration doesn't affect battery life on your phone. It's just for accurate readings -_-"

Yeah man, Ive got the same problem.
If I charge it for about 3-4 Hours, I get a max of 5 Mins or so, with Wi-fi on.
When the Battery is about 10%, and I put it to charge, It immediately says 99% charged.
I've changed 2 roms, and still no effect, infact, its got worse.
Even Juice defender (even the ultimate version) dosent work, Not even Underclocking.
I saw the battery recalibrating thing and Ive wiped the battery stats, still no use.
I think there's a problem with the battery itself?
Im just sick of it.

I also think that the battery itself has a problem, not any ROM. I'll go to service for a few days and I'll tell you about what was the problem.

Anyways, thanks man
If it's deformed, then your battery's life is over, that's it, get a new one.
You can try the freezing method to try and squeeze it for a bit of juice:
Charge to 100, Plastic wrap, in the freezer for maybe an hr (not too long), take it out, put it in your phone, charge it till it says fully charged, turn on your phone and check duration.
seems a deep sleep issue
Just abuy a new battery. I suggest a Anker branded one. Search a battery review topic at the Accesoires section. If you buy the Anker 1400mAh, your battery life will be even better than the original battery life. And Anker is trusted and cheap.

I listened to your advice and bought a new battery, now I'll see what was the problem, battery or maybe hardware/ROM. I'm charging it now. Any advice how to charge new battery? Advice for scripts or ROMs? I'm going to use nightly cooper cm 7.2 and juice deffender. What about cm9 and this model?

Since we're in 2012, I'm guessing it's a lithium ion battery.
Just plug it in and wait for some time (~15 minutes)after it reaching 100% to actually fully charge.
It would be best if you don't let it discharge below 20-30%.
Read more about lithium ion batteries by searching around the web for more info.

So, How did it go?
Was there a problem in the battery?
or, is something wrong in the phone?
there was a problem in battery, I bought a new battery, not Samsung, but also has 1350 mAh capacity, and it's 2nd time on charging, life is about 2 days of using, average 2-3 h 3g, and playing games, half hour voice and maybe 30 sms and mails, and for me this is a very huge improvement from 15 minutes before death battery. Cheers, sorry again on my bad English

Hmm, I did get slight improvement once i calibrated using another app.
But Im still getting a new battery
anyone knows why phone's display blink-up randomly? I saw that earlier, and I thought that was because of battery, but obviously, wasn't that. It's totaly random. And, I have another question, I've played with *#*#4636#*#* code, and sometimes phone can't receive or sent messages, except when preffered network type is GSM only and only after turning on and again off airplane mode. I have cooper cm 7.2 newest nightly ROM.

I had the same issue when I was using Elegant white by TAZ.
But Then I flashed a fix for it.
I suggest you should too get in touch with the dev.
But first, flash the rom again.

Thank you. Anyone knows where is the official topic for cm 7.2 nightly cooper? I found one topic in development section, but at the end of it someone wrote that topic is closed on developer's request. And where I can find changelog? I saw that there is newest nightly update from 19.8. http://download.cyanogenmod.com/?device=cooper
