Just curious if anyone else here experienced this...I plug my charger in (AC or through my computer) and what shows up it's charging, isn't it's actual total.
IE, it shows it's charging and it's at 85%...but if you unplug it, it'll show up it's really a different level, sometimes less, sometimes more. Heck, one night it sat on "charging 37%" for 8 hours while I slept and was still like that when I woke up...but when I unplugged it, it was really fully charged.
TMO is sending me out a replacement device, so I'm really not worried about it. Just curious if anyone else had this happen to them?

If you use the DS driver version of faux's kernal, it's well documented that the battery readings will be wonky...but your phone should run cooler. The CM driver version has more accurate readings, but is reported to run hotter.
edit: Waiting for next post: "Which one is better?"
Nope, it won't be "which one is better"...it'll be...how do I know which of those I'm running?
Also, that's just what I'm currently running. I've flashed nightly files, EB, etc...all with the same.
As I said, TMO has shipped me out a new device, so I'm not worried about it. Just curious if anyone else had this problem (which you say it is wonky with certain driver).
my lg g2x drains my battery when turned off
the most previous experience was last night when i had my battery at 39 percent when i turned it off the next morning when i turned it on it was at 19%...
At first i thought it was the faux's DebouchedSloth (the one with the funky readings) so i paid no mind to it. (i just left it on during the night in airplane mode, which actually gave me better battery life) Later, i flashed the trinity kernel, only to find out the same thing happens
what do i do?
im running the latest cm7 kang build from baldwinguy77 with trinity kernel T15max 20122011 if thats any help.
thanks in advance
try a "battery calibration"
let it drain out completely and then let it charge 1 to 2 hours extra after it has reached 100%. worth a shot but i doubt it will help
or try wiping battery status in recovery
also, set up setCPU with profiles
Hmm.. I wonder how the battery drains even though it is off? o_o
Did you try turning it off, than remove the battery and put it back in? And see if it drains.
For me, my battery drains 0% overnight on airplane mode.

I just want to make sure when you say you turned your phone off you mean you shut it down right? I'm just trying to get a answer out of the way because I have seen so many post go a long way only to find out the original post misinterpreted a phrase. If it was in sleep mode a 20% battery drain isn't terrible. I've seen better and worse. If it's draining while it's shut off then I ask are you using the stock battery? It seems to be a big issue and I could easily see it leaking energy while off or giving misread.

there was an article on the xda homepage posted not that long ago. it was about how battery calabration doesnt effect battery life, but only the battery graph found under settings. basicaly it said that the batterystats.bin file only has to do with that battery graph, it tells the phone whats been eating the battery. here it the link if you want to read the article:

anyways back to the point. nope i calibrated my battery a few days ago, so it didnt help

i dont know... and i used to leave it on overnight in airplane mode too with faux's kernel, it drained alot less leaving it on over night then turning it off. but the thing is, leaving you phone on for too long makes it sluggish, so i want to turn it off once in a while to help make it more snappy. I wanted to try that with trinity kernel, but ya thats not really working lool

I would suggest trying a new battery first. I purchased a couple of 3rd party batteries for $20. If it still drains while the phone is OFF, you have some sort of internal hardware problem.

sometimes it's the ROM, i've tried EaglesBlood, PheonixBlood and i get above then norm battery life. I'm on Xboard's OTA and my battery life is sweet
i'm having the same issue as well even when using 2 different batteries and an external charger (for the battery itself).
'normal' drain on the eaglesblood AOSP is about 20% an hour and when I turn off the phone, remove the battery, put it back in, and turn it back on after an hour, the battery drains till it's almost empty!
maxesxp, did the new batteries work? or was it some combination of rom + kernel that did the trick for you?
Weird I just thoughts about looking for this cause I had this happen for the first time. I was at 40% had no charger around so turned the phone off, turned it on the next morning and was at 2% effing weird!
Sent from my LG-P999 using xda premium
My phone does this too. Some days it will drain only a percent or two and others it will drain like 20-30%. From what I can tell the kernel or something is not turning everything off on the phone. Try turning your phone off the next time you do and remove the battery and then when you go to turn it on put the battery back in and see if it drained then. If it did then it is a problem with the battery and if not it is a problem with the phone. If it is the phone there is not much you can do about that, sorry.
Note: I searched the forum and saw nothing like my issue, if there is then I missed it and I apologize.
So here is the issue. When charging it gets to between 85-90% then immediately jumps to 100%. Have tried clearing the stats, draining, then full charge. Any suggestions on this?
How old is the battery are you charging USB or AC?
Most likely its a old battery

very odd, I've actually experienced the inverse. Charge would hold at like 20% and then jump to 10% in a second. Are you noticing in use there is a jump back down i.e. when you unplug, does it jump from 100% straight to 90% or does this just happen when charging. If it just happens with charging, I'd say run current widget and see how much mA is left when it makes the jump to 100% and see if the battery is actually charging correctly. In other words, if you're charging and the battery jumps from 90 to 100 and you still have like 200 mA left, something is goofy with your battery and I'd recommend a new battery or at the very least full wiping and reflashing your ROM.
If it jumps and the remaining mA is like 30 or something low, then the actual battery seems to be fine and I'd recommend a full wipe and reflash the rom you're using. In all honestly, it's probably the battery and may just be worth getting a new one.

Im not attacking you im just trying to clarify. Are you saying it jumps to 100%, meaning you see it say 100% or are you referring to the led going green at about 90%?
I'm not convinced it is a battery issue... I've only very recently rooted my phone (have had it for 11 months) and haven't had the charge indicator jump past the last 10% like it did just today.
Looking at the last 26hours of history (ICS 3.0.0 install), the initial battery discharge showed normal taper from 100-85%, however on charge it jumped from somewhere just below 90% to 100% instantaneously.
I should have taken a screenshot, but instead I wiped the battery stats and am in the initial discharge cycle still. I've had the phone 11 months and have never cleared the battery stats before.
Maybe 8 months old.

Run the battery down until the phone dies. I have had this happen to me before. When I got down to 1%, it took a really long time for the phone to die. Recharging and doing a couple of long cycles of letting the battery go down to a really low level before charging fixed it. Do not delete battery stats as it does no good.

You might try an app called Battery Calibration. Found here http://forum.xda-developers.com/showthread.php?t=1024867
I don't necessarily use it to calibrate but to monitor the mV. It might help in seeing if it is in fact a bad battery or if your battery indicator is showing a false reading.

Sounds more like a battery calibration issue than a battery issue.
Give it a bit of thought... from 90% it skips to 100% when charging. However at 1% it camps out for an hour or more before shutting off. This indicates an issue with how the charge of the battery is being measured/expressed...
Now let's think about what is happening behind the scenes. This measure of charge is "defined as the available capacity expressed as a percentage of some reference, sometimes its rated capacity but more likely its current (i.e. at the latest charge-discharge cycle) capacity but this ambiguity can lead to confusion and errors. It is not usually an absolute measure in Coulombs, kWh or Ah of the energy left in the battery which would be less confusing. "
Essentially, the way the phone is measuring the battery isn't working correctly. However, is the duration of the battery life what you would expect given your use of it?
If YES, then it's a measuring issue.
my NS4G with MIUI 2.6.1 and Matrix 20.0 Kernal goes to 98% as soon as i pull off the charger. if i use it for 45 minutes unplugged its dead. if i use it while its plugged in, it will die!
should i get a new battery?
Yeah that doesn't happen to me... I would try a full wipe and reflash the same ROM (or a different one) and reflash kernel.
If that doesn't work then I would try another battery because that drain seems abnormal
I just wanted to say that I have been having similar battery problems. Using the exact same ROM and Kernel as the OP, today my phone died within 6 hours of use, with the screen having been on for no more than 50 minutes. I also turned off data, and sync during this time, and had my screen's brightness at the minimum.
I've wiped and flashed AOKP b-38 today, and the consumption seems to be much better.
Any thing to help?
thought i was the only one.
is it the kernal?
or is it because its time for a new battery?
How could I test to find out which it is...
Swap kernels. Probably easiest way to test.
Very possible its just an old worn out battery.
Sent by pocket technology.
hoping its just an old battery.
ive switched to CM9 / TouchWiz mod thinking it might be the ROM
im going to use the stock kernal from CM9 for a day to see if i could tell a difference.
ordered a new battery anyways.
saw on a forum somewhere a guy complaining about this problem since he switched to ICS ROMs .. hopefully thats not the case because i LOVE 4.0.X

Well in that case, what have you got installed? If you have apps constantly syncing, that could be part of the problem. What are your battery stats saying is using the most battery? My phone gets warm, but as expected since its being used. If its not being used,it could be a rogue app or the phone could be constantly searching for a good signal.

also its so bad, that if i start using my battery when its @ 10% PLUGGED IN, it will eventually die on me. even though its charging..
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.

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.
