Can not recalibrate battery

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....

Need better Battery life!!! help!!

hey im using leedroid v1.3 and the battery life on my phone is horrendous, i left the house at 11am this morning with 98 percent and after a 10 minute phone call i had 75 percent battery by 12 oclock. do you guys have any tips or things i can flash to get the phone through a day and a half or even 2 days somehow?
also having an issue with the speakerphone, its the lowest volume of any phone i think ive ever owned, ive got to put the phone to my head, so its basically like making a call but using the back as an earpiece. thanks for the help.

I'm having the same problem with my phone, on any rom. According to CurrentWidget, the Ma being used by my phone will not drop below 150, even while idling. I'm starting to believe that my battery is faulty.

Are u guys calibrating the battety?

I thought I was, but apparently I'm not. Can you point me in the right direction?

Download the battery calibration app from the market. Charge to full run the app calibrate.....drain than calibrate again and you should be fine.

Upgraded to v2 and ran the battery calibrator. Phone finally lasts a day. Thanks. Am I supposed to run the calibrator at like 10% or should I let it die and run it after a 100% charge?

Battery calibration + managing screen brightness massively increases battery life. You need root to be able to clear battery stats, right?

I believe the calibration tools want you to use them at 100% charge. I got a chichitec 1900mA/Hr battery, calibrated (i guess it is now) and my phone went for more than 24 hours before hitting the 49% mark. This was with light use (checking email, checking web forums, playing some Angry Birds, and making some phone calls) but still a HUGE difference from the stock battery. Also, I turn off data connection via quick settings when I am at home. I do turn on wifi though while at home. Calibration ought to help out big time, as these phones are reporting a dead battery long before it is really dead.
Also, dont pay attention to the current battery monitor's report for standby current. It isnt accurate.
Matt

That's the one reason I keep going back to the stock setup I just seem to get better battery life out of is than any of the custom ones I've tried. I've only tried a couple. Has anyone found a ROM that gets better battery life than stock?

[Q] Odd battery issue

Hi everyone, and merry Christmas. I have an odd battery issue that has been driving me nuts! Every night when i turn my G2x off I lose between 15% and 45% if my battery life. I know this is not an issue with my battery because if i turn off my G2x and pull the battery out when i put the battery back in in the morning the won't even be one percent lost.
I have had this issue on multiple rooms and with multiple kernels. I have had this on EaglesBlood, cyanogen, weapon, and miui. I have had the stock cyanogen kernel, trinity kernel and faux123 kernel. The only time i haven't had this problem was back before i rooted my phone.
Any help you all could give would be much appreciated. Thanks all!

Note the battery charge percent, pull battery, put it back in, let sit overnight, turn on, note battery charge. If it discharged more than a percent or two, phone is probably faulty because it is drawing current when totally off.

This actually happens to me when I leave it off at work for a couple hours. Confuses me as well...

Phone must be drawing current while it's off, which I am pretty sure is happening to me as well. Damnit.

It is obvious that shutting off from the menu isn' t doing what it should, completely shutting off the phone. Backup your ROM then install a vanilla ROM without any additional apps, note battery percent then shutdown from menu and leave overnight then, in the morning boot it up and note if the battery drained. If it didn't, the problem is either an app or the kernel or rom you previously had installed.

So i temporarily went back to a stock ROM and it didn't seen to have the problem. Which sucks because i really don't want to go back to stock....

What's wrong with my phone?

Ok. I've had my sensation since day one. And some times I have a problem where the phone just turns off while using it. And then I have to pull the battery in order for it to boot completely. Before my phone tirned off i was at about 50%. When i got it to turn back on i was at about less then 10%. I've wiped batter stats. I have the anker 1900 battery it even does this with stock battery

Hmmm I see others are having this battery drain issue just like you. It seems the CPU or something is getting stuck in a on or hyperactive state. This is causing the device to malfunction. If I was you I would request a replacement cause from my personal experience with my first Sensation it will eventually die completely. I was typing a text message when it locked up and then shut down on it's own and that was all she wrote.

Might be a bad battery ever tried some differents one ?

+1 for the similar problem.... Kindly help me too.... I was about to post this question and i saw your post... Devs plz help us...
Heavy battery discharge + unable to charge battery till 100%, stuck at 83%... Done everything possible.. Using FlyROM v2 Kernel 3.0..

vishuhtc- You can try installing "better battery stats"(check out xda), or "GSam battery monitor", you will see what is killing it, if you don't get your answer with this apps check this thread http://forum.xda-developers.com/showthread.php?t=2093542 . Also if you are using super wipe, to flash roms, try flashing without it, or with it, but manually delete bootloader data, cos it doesn't do it automatikly
khanjan2khan- check out with the second app what voltage gets to your battery, it should be something like 4.000V or a little bit more, if it goes to that, you should also calibrate it or just delete battery stats from recovery, if it doesn't get to that............. try with another charger, or with a service center.
