My battery skips a percentage every once in a while. It's always the same ones too, 99 will go straight to 97, 46 will become 44, and a few others. This isn't the worst problem in the world but it's still weird. Clearing battery stats does nothing. Anyone know what could be causing this?

First and foremost, I completely understand the battery reporting is inaccurate.
I, like most of the G2x users, have occasionally experienced excellent battery life and at other times barely lasted 5 hours. We all know this has to do with the LG battery drivers. I think I may have found a potential stop-gap fix though.
Another preface:I'm running CM7 nightlies.
Now, using SET CPU you can set a screen off profile that will underclock the cpu to be more efficient and save battery life, anyone worth their salt knows that. The other aspect of this that I have been doing is underclocking the CPU during normal usage. With min set at 312 and max at 760, I've gone 4 hrs and 13 minutes with 96% left. Even underclocked, this phone performs. The only issue I've noticed is a little bit of buggery with the lockscreen reactivating but honestly it's worth it to me to have a phone that lasts.
The issue is with the battery drivers, nothing else, your "fix" are just ways to increase battery life

I'm 90% positive that's what the big red lettering at the beginning of my post says.
So even with no widgets, a black background, mobile data and wifi off, and sync off my battery dies so fast that ill go to sleep at full charge and its dead when I wake up. And no I don't use it in my sleep. I'm running gummycharged 2.0 if that makes a difference. Any ideas or thoughts? Its a certified pre owned phone so maybe its just a shot battery ?

I have a similar situation. Mine drains like that at work but not at home. No amount of battery calibration, different ROMs, different SIM cards killing tasks, switching phones or anything else makes a difference. They all do the same thing. In my case, I believe it is the constant fluctuation of the actual Cell signal (not data signal) that is causing this. To see if this might be the case for you, let the phone run for a few hours where this is happening but don't let the phone die. Then go in to the "Battery Use" then select "Cell standby". If you see any percentage >0 in the "Time without signal" statistic, this may be what is causing it.
Time without signal 30%. I think you may be on to something. you might have just saved me buying a new battery, thanks friend

You are welcome. Just wish I knew what the "FIX" was. I mean, other than moving - LOL!
been on bamf final for several months. battery fully charges and then goes from 100 to sudden reboot after 5 minutes or so. After reboot, battery is usually at 3-10 or so. No sudden reboots while plugged in. Awaiting a new battery from ebay. Any other ideas what this might be?
Id guess its battery mostlikely. If that dont fix it, unroot back to stock, see if it still does it, then call in.

To me, it sounds like a new battery will fix the problem here.

I hear a new battery might fix it.
Occasionally I'll look and see my phone battery has gone from 84% to 71% or something drastic like that- I look at the battery use graph and see a random and no-slope dropoff, happens when the phone screen is off, not in use at all.
Otherwise expect a reboot to suck 10%-20% of your battery.
OP here -- new battery in and working fine.
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.

So... I'm on Beanstalk 1.300 by dwack!
Problem is battery keeps dropping to 0% and shutdown the phone while i'm on apps or 3G or Wifi and even camera.
Then i left the phone sit for 30s, boot it up, and battery went back to 60% (where it was before).
Does anyone else suffering from this or just me?
Is it my battery that cause problem?
You most likely have an expanded battery. Place it on a table and see if it spins, if it does then buy a new one. If it doesn't, buy a new one
