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.

My Galaxy 3 battery is behaving quite strange for a month. Problem is my battery never gets above 4181mv which is why I never gets full charge of 4200mv and then it goes to 0 at 3650mV which if we do some maths should be 45%. The problem is due to this i am not able to get full backup, hence no proper calibration. My battery now lasts for hour. Sometimes there is sudden drop from 60% to 0 at 3705mV. I need to know if there is any solution to this before forcing me to buy a new battery. My current battery is 9 months old which came with phone.

By trying another battery.
I'm in the process of getting the ankers, but my stock battery is trash period, my battery stats show like that, I can be at 30% then reboot and be at like 5, but I can plug in before a reboot and then be at like 50%. I know its going to kill my battery eventually like it did on my buddies G1, and I know that's an old phone but his was doing these same exact things and one day he took it off charge at 100% and 30 seconds later went dead and we never got that battery back.
Last night when I got home my battery was like 30% and I was showing off pix from the zoo my ds just decided to say low battery and shut down. So I gave it 5 and brought it back up with 20%? So I would def think its the battery, seems how hot the stock one gets

Exactly same problem. Sometimes it would be at 12% like for 1 1/2 hour until it gets to 11%. I noticed that my battery drain pretty fast when it gets hot. Eventually my battery works great,I think is the phone. Where I can find de ankers at the lowest price?

Has this happened before to you on other builds of AOKP or other ROMs you have tried? Has this happened to you before you got the extended battery? Sometimes Android will randomly incorrectly report battery statistics such as percentage remaining. For example, it might say 10% left but that "10%" will last for another 2 hours.

Is the battery new. Has it been conditioned. Drain completely and recharge. Then go from there. Not enough info in 10 minutes to tell what is going on. Install Bettery Battery Stats to see what is running. Gsam Battery Monitor will also give more info on what apps are eating the battery.

After you follow these suggestions if that still doesn't work consider whipping the battery stats file to prevent potential incorrect battery stats usage (You can do this in recovery or by downloading a battery "calibration" app).

I'm still negotiating the hyperion battery issue. The phone does not read the stats correctly with one installed. Battery life is correct but stats are wrong. I think it may have to do with the Jerry rigged nfc that was added to their previously made stockpile.

HaHaa. They got you too?
Yup, was drawn in by the extra 200ma/hr. Pretty sure the stock battery is better, but cannot get any accurate calibration on the hyperion. Which ultimately tells me that there is a fluctuation in the output of the battery. That can't be good for the system... Kind of like using a construction grade generator to power a pc, it'll work, but is it safe? Stopped using the hyperion batteries, keeping as backup.
I actually picked up a separate charger. I just leave the Hyperion in it for about 12+ hrs. I downloaded battery calibration app and it seems to be doing a lot better. Not like the first time I put it in but lasting the entire day. Thanks for the help guys..

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.
Sent from my HTC One XL using Tapatalk 2
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.

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.

I am using an extended battery as well, please tell me what to do I was on GB before and the battery was outstanding, I could go on one charge the whole day with heavy usage, now i dont think I can make it through the day with light usage on this
thank you
EDIT: This could be a sleep problem, because when the device is on, the battery is normal
If you flashed the Feb 27 cm9 you should flash proton kernel so you can watch videos. Battery life isn't as good as gb no matter what you do. Also give it some time to settle in. It takes more than a couple hours.
alright thank you... I just flashed the newest version of cm9 a few hours ago, I was flashing a bunch of roms and this one seemed the best... do you know how to force a device into deep sleep cause that seems to be the problem i believe
OK I was just on 20 percent, then i rebooted my phone, and now im on 2 percent... im seriously considering going back to gb
Sounds more like a battery thing? With CM9.? + Proton I'm getting at least a day* with light use. Maybe a bad app or combo of apps? What does BBS say is eating the charge?
* - I say at least a day because I can't not use it for that long.

just the screen and the android system... very interesting thing though is happening
I'm running a bunch of quadrants to get the battery down to 0, and the battery is all the way down to 1%, however it's been on 1% for like 6 quadrant tests... maybe its just a problem with the indicator, however another indicator also says it's at 1%... very interesting
If you are on CM9, I suggest you flash Hefe or Proton.
I use Hefe because according to the posts being made it puts your phone into deep sleep, which means longer battery life.

Definitely a battery problem. This happens to me on one of my batteries but not on another. Time to buy a new one. I haven't tested it fully but it does appear to be just a display issue. Sometimes the bad battery will make the phone display 1% but it will still act as if it had way more than 1% charge left. I haven't done any testing on that regard but that's what it appears to do.

I don't believe it to be a battery problem, because I've been on GB with absolutely no problems and exceptional battery... I just upgraded to ics not long ago, and the battery life instantly screwed up
Have you set the cpu governor to anything silly like performance?
Have you let it charge up fully at least once?
Search xda for "better battery stats" app, use it to see if you're getting deep sleep.
Flash hefe over release 8 and youll have a little better battery. Proton doesnt deep sleep

Proton DOES deep sleep. That was one of its major features.
Certain scheduler/governor combinations work better on different kernels, though. If the specific one you like most sleeps better on Hefe, great. If the one you like does best on Proton, great. Just be aware that most issues are either physical or user-inflicted...
In this case, your battery is almost certainly dying. The variance in power over a reboot is a definite tell that your battery is probably swollen. If you can spin it on a table, the cells are starting to die. This does not mean you can't keep using it, but it does mean that your battery life will be irregular. It also means that you'll have significantly "higher" battery levels if you reboot the phone with external power connected, but the battery will discharge very quickly if it hasn't actually reached whatever level it believes it should be at.
