Im trying to recalibrate my batter because of terrible battery life. After letting it die and charging it while its on I had no issues getting it to 100%. I powered down the phone to charge it while it was off and it seems like its hanging at the last percent and wont go to 100. I have had it plugged in for a few hours now and its still showing the same charge but wont fill up the last little bit of the meter. Anyone have any ideas? Im really thinking about tossing the battery and getting a new one. It seems like i got a bad one. no matter what I do i can only get about 12 hours of light use. I work 10-12 hour days so I have to constantly worry about my phone dying everyday I work.
I had the same issues. Tried every battery trick I found on the forums, but nothing worked. I went to ATT, they sent me a new battery and it everything's good now
So try talking to ATT and getting a stock OEM battery before you buy one
I picked this up and it gives a lot of peace of mind: http://www.amazon.com/gp/product/B004206TQ8/ref=oss_product
Dngen. Are you getting greater battery life now that your using a different battery? I'm convinced the first batch of batteries and phones were bad.

At first I thought it was the phones that vary in battery life.
My first captivate had really good battery life. But it bricked after I tried to do the JH7 update. So I got the phone exchanged, but they used my original battery in the new captivate. For some reason my phone was draining really fast compared to my old captivate, and this was weird because both used the same battery.
This was really annoying me cause I loved this phone, but the poor battery life was ruining it for me. So I went to an AT&T store and told them how bad my battery life was. They shipped an OEM battery for free and I've found a new battery to significantly work better than the old one
Hmmm. I just got a replacement phone and everything works better...GPS ect... but the battery was the same as it is now.....10-12 hours. I've been thinking about getting another battery but I don't know if that will fix the problem. I guess I will try to anyway.

How long have you had your replacement phone? I know my battery life got better after a few days with my original captivate
I got my replacement phone about a week ago...I've been trying to drain and charge to make sure the system is getting a good read....I've had the battery since launch...the only time I got great battery life was when I used unhelpfuls undervolting and the first time I flashed jh7. I have only flashed one rom on my new phone. It just bothers me that it drains 5-6% an hour in idle. I don't have any Widgets and the only thing that is updating is email once an hour

I think I might have caught a break....on my fourth day of charging and draining and I'm at 16 hrs with. 27% left. I guess ill continue with the whole charge and drain thing for the next couple of days.

I somehow doubled my battery life. After draining and charging the last few days I managed to go from 12 hrs to 24 hrs of battery life while using it the same amount as before. I have had had my phone since launch and battery life sucked. I don't know it its because I got a refurbished phone that did it or what. I flashed my old phone almost every day for awhile. Even when I didn't flash I couldn't get it to last.

Have you guys seen this thread?

Good stuff, thanks
I've seen it and read most of the battery threads out there. I've come to the conclusion that: 1. There's a bad batch of phones out there that cause battery drain issues or 2. Since most of us ATT android users are new were unaware of the proper procedure to flash roms. I believe the second to be more true since most of the batterry drain issues happen due to flashing new roms according to most of the threads I've read. I would like to see the percentage of people out there who are still running there cappys stock with never Modding or flashing to see what type of battery life they are getting.

Before rooting, sideloading and flashing unhelpful kernel I was getting the same battery life, 10-15 hours depending on use. The only thing unhelpful seemed to help with was my idle usage, about 1%/hour. I still need to tinker with the kernel and try wiping my bat stats. My phone reports the battery is at 5% but when I shut it off and plug it in it's more like 30% lol

I had the same issue. Charge until full. Turn off and charge full... turn on and repeat. Erase battery stats via CW. The key is to let it die. Do not charge your battery until it dies....once it died I plugged it in and turned it on. If its at 1% then just let it charge completely. If its at 30% then you need to unplug and let it die again. Keep doing this until its at 1% when u plug it in. If you have to do the latter you have to start the process over again and erase stats and drain and fill the batterry. From here on out anytime you flash a rom make sure your phone is at 100%. Always let the phone die before charginging it the first time. I think the android system has to get a read of the batterry.
I think at some point along the way I charged my phone when it was at 30% after a flash so anytime after when my battery was dying I still really had 30% battery left but android was telling me my phone had no juice.. let me know if this works for you....

Purchased this morning and the battery was drained... Fully charged at 5:30pm. Now at 7:30pm im as 50% with minimal use. a 4-5 hour battery life is not going to cut it.
Hopefully this is just an initial charge issue, but my vibrant never drained this fast.
Worried!
U may actually have a bad batt. But id give it a chance. Drain it down to 0. Turn it back on. Let it die again.
Then charge it while off. If it happens again youll know.

I have done a few charge cycles completely draining it and battery life is still pretty bad...it better get a lot better than this or it is going back.
Also getting random freezes and reboots.
I've got a ton of apps and widgets installed and use Exchange push. Battery life has been just a little worse than my G2. The phone froze after I first configured it and I had to do a hard reset and rebuild it. It runs a lot better after the reset. You might want to start-over and see if it make any difference for your freezes and resets. I'm purely guessing it may be the difference between the phone configuring the SD card and reading off of one that's already configured.
Bad batt. 4 hrs is a wayyyyy bad.

Sounds like my experience too. My battery yesterday lasted me no more than 7 hours. Wooh, I was pissed. So far today though, It's been on for 14 hours and I'm only down to 25% with some medium-to-heavy emailing and texting, and a few 5 minute phone calls. I'm very impressed after this second charge. I'll drain it again tonight in hopes for a little additional life. Stick it out for another day or two, OP.
I'm really concerned because I've had my phone since Monday and have charged it at least twice a day. It's not getting any better :-( I have even froze alot of the bloatware and apps that run in the background. I can't handle 6hr battery life :-(

You mean for an exchange? Or ask for a new battery? Will they do that?
I also have serious battery issues. The battery usage is mostly consumed by cell standby and bluetooth. On my mytouch 4g at most these parameters were a few percent each. On the g2x they are like at 25% usage each. This does not appear to be normal. This is with minimal to no usage. I dont get it. Is it a software issue, there is no reason cell standby and bluetooth should be usaging so much juice with little to no use.

Root your phone, after that install Titanium Backup from the market, and once you load titanium backup, you can actually go to Backup/Restore and find the app that you want to freeze, click on it and choose Freeze.
Once you install Titanium Backup - it will ask you for root rights - click on "yes" or "allow" (dont remember exactly which one it was" so you can provide root rights for it.
Anybody know of documentation on best way to calibrate the battery? I did 1 discharge - charge cycle... how many more do I need to do? Do they need to be back to back or can I keep it plugged in while using it today?

My battery lasts a little less than my NS or vibrant. It should at least give you 5-6 hours of HEAVY usage. I left the house yesterday at 10 and by 6 it was done. Since it's a new unit I used it heavy, plus I rely on it for scheduling and contacting clients about every 30-60min. I was also playing games on my breaks.
You probably have a bad battery.

I do seriously think that there are a lot of improvements that will come in a software update. The Cell and Wifi usage are ludicrous and it's probably a matter of getting the phone out the door with an update to follow.
This is only the second Tegra 2 phone to be released in the US.
2nd day with the G2X and the battery life isn't getting any better... If anything it's getting worse...
90% at noon and 20% at 2:40pm. Plugged in at 2:40 and now 20 minues later im back at 88%
Drains way too fast, and seems to charge even faster...
This phone is faster is every way compared to my vibrant, I just wish this wasn't true for the battery loss..
I'm having a weird issue with the battery gauge on the CM 9 Alpha 3 and 4 ROM's. If the phone is rebooted when the battery is between ~40% to 70% it shows that the battery will drop to ~15% immediately after rebooting. I've been through calibrating and wiping the battery stats both with the calibration program and through CWM recovery. The battery is showing 3759mV at the time it's reporting 15% after the reboot. I've tried 2 batteries which are both stock batteries, one is about 6 months old and the other is 2 months old. I never noticed this as a problem before, I was running pure stock up until 2 weeks ago. I had the MIK Rom on it for a week, then put CM9 Alpha 3 last week, and Alpha 4 this morning. You can see the "display on" time and massive drop at reboot on the attachments. It also reflects the drains while I was making calls and playing throughout the day. Am I missing something or is there something else to check?
Thanks, I really like this ROM and hope this is just a glitch or me missing something.
The stock batteries are infamous for their very low charges. Get an aftermarket battery.

I've been reading through the battery posts on here and am leaning that way. But even with that in consideration, I wouldn't think there would be such a dastric drop like that, and I didn't notice this before until I put the new ROM's on. I'm thinking about going back to another ROM and see if the problem still exists there.

Nope, just the touch screen.
I know that Lion batteries do not have a linear discharge slope, but with the mV @ 3759 that should reflect ~50% I believe, which is where the % showed before the reboot. But, I didn't check the mV before the reboot. That'll probably be the next thing.
I pulled the lines from battery history.txt file on the sdcard. It looks like the mV dropped around 20mV but the % dropped 40 from the reboot. I streamed videos on YouTube for about an hour and it dropped to 9. Finished it off after that and the phone shut off around 3293mV. The first lines are the reboot.

My stock battery does better than that, and never jumped between values (except with the CM 7 kang). With stock Android and now CM 9, I never have that issue :\
I saw a post in the ROM thread that user jarnom had the same thing happen with the battery gauge. I had it happen again when I was at 50% and after the reboot it was @ 6%. I tried what they did, pulled the battery and waited a minute. Powered back on, and the gauge went back to 48%. I never though about pulling the battery, but it worked to get the gauge back to where it should have been.
try Calibrating your battery?
have you tried calibrating your battery? it is recomended to calibrate after your flash a new rom. first time i calibrated my bat life went up at least x2!
not here to advetise any specific app so search "battery calibration" in the market.
hope this helps?

Yes, and no, at the same time. The actual apps that wipe the batterystats.bin file doesn't do anything but remove the file that stores the usage history of the apps. Seidler2457 pointed that out here on the site.
I did start using battery widget pro to see what it showed compared to the phone as it learns the minimum and maximum values for the battery after multiple complete discharge cycles. It estimates time left on the current charge pretty accurately using the current mA draw on the battery. I use my phone until it is dead at night, and then recharge overnight, so it has a few good complete %1 to %100 cycles on it. It's not affecting the battery life that I can tell, I'm getting the same average times out of the battery every day. Actual battery life has been really excellent on this ROM, it's just a weird issue I noticed.
hey, having a sortve similar issue except now the phones battery isnt even taking a charge ._.

That's the mA field, (current going to/from the battery. Next to it is the % field, then mV, and finally temp. It was showing a - value when the phone was using battery. It does that periodically when the battery is fully charged and still on the charger.

I've noticed the past few days, after flashing ICS, that my battery hangs at 77% while charging. I completely discharging it right now and deleted battery stats in recovery. My phone is only two weeks old =/
I flashed Alpha 5 earlier tonight and have rebooted 8 times now to check for this issue. Every time the battery stat has come back at the same level as before the reboot, which is awesome. I'm not sure if anything was changed specifically, but the nuisance I had isn't there now. I flashed over Alpha 4 with just a cache and Dalvik wipe.
Hi everyone,
I'm currently running CM10 on my AT&T One X. It runs great, but when I hit 6% battery, it suddenly jumps to 1% and shuts off a few seconds later. I've tried recalibrating by using the app available on Google Play, as well as letting it shut off and recharging all the way. Neither have seemed to fix the issue. My question is; are there any other ways to recalibrate the battery, or simply cause the battery indicator to display the proper percentage?
Thanks to anyone with advice!
Have you looked to see if anyone else on CM10 reporting anything similar?
In any case, the battery meter is not all that accurate in the best of conditions. I wouldn't trust the meter being below 10% to mean you have much significant battery. Really, by the time you hit 20% or so, you should be looking to charge.
Why you letting it get that low? Normally around 10% I plug in.

It's not habitual or anything. I just normally don't plug it in until I go to sleep, and sometimes it dies before that time comes.

This isn't based on facts but my 2 cents is that because the calibration of the battery isn't wiped, it's not accurate. There's no wipe battery stats in TwRP. If you ever notice the battery percentage in TWRP after flashing many ROM, it differs from the actual phone.
I wipe the batterystats.bin in data/system when full then reboot but who knows if that even works. I had my phone turn off @ 3% once so who knows but charge it as soon as it gets in the teens. Its bad for the battery if it keeps powering off when low.

You're right: that isn't based on facts.
Battery stats get reset every time you charge your phone. Manually wiping them does nothing.

This issue has been discussed in other threads. Seems to be specific To CM roms only.
Some report steep declines from 40% to zero in seconds. You seem lucky.

I wouldn't worry about it. Mine turns off anywhere from 5 to 15%. The battery percentage is just an estimate based on the software, it's not an actual indicator. As such there are tons of variables that can affect when the phone is actually out of battery.
TWRP also doesnt report battery correctly and it has nothing to do with the stats. It is taking more of an educated guess as to where it's at. Believe it has something to do with are phones.
thanks for the info.. i have experienced this issue also
Battery percentage is guessed at based on voltage. As the battery drains, voltage decreases slightly. Yes it is an educated guess. Every battery behaves slightly differently and has a unique profile or discharge curve. Some may be steeper than others at the end, but the device should learn this and adjust accordingly. An internal short in a composite battery like this would also exhibit this behavior, only exhibiting itself at certain voltage levels(dependant on location of physical short in battery) where voltage drops to 0 at that moment. I have seen this issue in defective packs where they work fine most of the time, but then zero all of a sudden. I'm not saying this is your problem, but the case design/new soft shell battery(no hard plastic shell to protect against the internal layers from being squeezed together) is wide open to physical damage from the phone being compressed.
Try a stock ROM and verify it works normally. If not, the battery is damaged.
My One X has never shut off before it reached 1%. I unlocked it 4 days after getting it in the beginning of June and have been running CR ever since and never had a steep battery decline.

Ok on start I am sorry guys for my language. I am in UK only one year so I need to learn a lot
10 min a go I back from SSC because I have problems with battery/ charging and foulty speaker
Italian Job 1.0.0 - big battery drain and battery go dawn after restart by 30-60%!
XXMC8 - no battery drain but battery go dawn after restart by 30-60%!
Stock UK GB XXLK7 -no battery drain but battery go dawn after restart by 30-60%!
So I bought new original samsung battery 1500mAh - no changes
So I bought batttery 3500mAh with special cover - no vissible battery drain, this battery can handle my phone by ~ 20 hours of playing AVI movie, 720p in loop in MX Player so very good score but battery go dawn after restart by 30-60%!
All battery was tested in my Ace 2 and in my girlfriend Ace 2 (she have fully working phone with no problems) and she have good scores on all batteries but best is on 3500mAh with special cover ( above x2 than standard)
So i went to SSC and they: (stock GB, 0 flash counters)
- take my phone without documents on free guarantees (only box)
- I must come back for that phone in this friday
This above is for + but:
- they **** that work because I have in my ducuments copy a lot of bugs! (street , town)
- they checked my speaker in noisy room (it did not take nearly as booming)
- for those guys after restart when phone loses 30% battery power is normal!
So I go after tomorrow for my phone and we will see ( They will make updates to JB! and they change speaker/ charging module)
Photo for proof attached
If they dont repair my phone I do not buy samsung phone NEVER AGAIN!
EDIT: 3 hours waiting for a response about taking my phone!
EDIT 2: that 3500mAh battery must be loaded 8 hours to get 100% form 0%. (standard charger )
I really want to know what the whole battery dropping after restart thing is about, forever happening to me and sometimes the battery completely dies. It was the same on my original Ace S5830 I got a few years ago.
If you find out, please tell! haha.
After receiving the reply I upload it here
Have nfc version and ni problems with battery with much using and sometimes little bit playing i rech two days
I dont have problem with battery (any) but with phone hardware
I must agree with you guys regarding battery drain. It's suspicios and I am also aware of a fast battery drain from 100% to 65% in just a couple of hours, or very fast after a restart.
Maybe this is the way android should work. I was thinking there was a problem with my phone, but seeing similar behaviour with yours, it must be something related to the android system.
I'm on JB me1 and i haven't this battery dran problem. After the night i just lose 3-7% battery
When I have 100% and I off my phone and turn on battery go down to 50-60% immediately in one secund! It must by hardware foult...this is not normaly working android, for me
Really i don't have sth like that so that isn't real android

well i dont have that
sometimes when i reboot my phone it goes from 45% to 47%
and some times from 45% to 44%
This is ok
I thought that is not really a battery draining. But it just about battery calibrating. Your phone need to calibrate the battery. Thats the problem.

lol actually "calibrating" is just a myth. It doesn't really do anything.

Really??
However, I've never done any battery calibrating..but I read in some thread, need to calibrate the battery, so there will be no battery misdisplay on the battery icon...logically, I thought, our devices will some time miscommunicate with the battery because there are no battery parameter to make the system understand how much the battery stored....
But I don't know if it just a myth...

its normal to see 99% when unplugging from charger, 3%-10%(Max) drop on rebooting. Battery is usually inaccurate after charging, what I do is plug it in then reboot. then it displays the right value after unplugging, usually my battery status is really inaccurate but it returns to normal afterwards (it'll show charging icon even when unplugged and charge to 100 then stops and returns to real level). I don't believe in this calibrations and have found enough proof its useless, I think most xda users agree too. Try searching some threads.

Actually you don't even have to search xda, there you go fellows: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT If this isn't enough then I don't know what is.
My phone back to me from SSC with xxlk7, so no JB...(after 24hours in service)
If someone want to know how good is 3500mAh battery please go to my battery thread in general section.
