Ok so last night i connect my phone to the charger it has 16 percent battery left i went to bed got up 6 hours later it only charged 3percent from what it was at .
I plug the phone in at work charges from 19 percent to 32 percent go take the phone off the charger it drops to 16 percent.
last month I changed the charging cable and even purchased a new battery as i was experiencing the exact same issues up until I replaced the battery and cable but now the issue is back.
i was running Cyanongen mod 9 Nighties but have been using version 10 alphas since then.
Anyone know what to make of this?
What kind of battery is it? Not one of those cheap Chinese fakes is it?
Battery would be my prime suspect anyway. Not if its a samsung or polarcell or suchlike though. Do you have another one or know anyone with same phone to lend you one to check?

I had the same problem on CM10 nightly once, started charging below 20% and the next morning it didn't go above 30%.
Then I just rebooted and the battery indicator showed 100%! Seems like some bug in the battery info thing, since after the reboot the battery lasted as long as every other day.
So just try rebooting, if that does not help your battery might indeed be defective.
try charging the phone while its turned off to 100%
and then wipe battery stats from recovery

So I was running cognition 2.4.1 for a long time, and my battery life was awesome. It would barely go down at all if I didn't use it, and would make it through the day with about half to spare. On normal days I unplug at 630am and at 5pm it would be at ~70% (if i didn't really use it at all). Even if I did use it it would still last a long time.
I finally decided to flash a new/different rom and thats where my problems started. I flashed Assonance 5.0 and the battery life got worse (at 5pm i was at about 45%) so i just assumed it was the rom and that cognition was better on battery life. So my next flash was back to cognition (a newer version, b7 i think), which improved battery life, but it was barely noticeable, and was no where near what it used to be. Next I tried pheonix v1.5 and that was probably the worst yet, as my phone almost died by 5 oclock.
Finally I decided I would go back to cog 2.4.1 even though it was outdated. I figured this would solve all my problems. I was wrong as my battery life is absolutely terrible right now. At one point yesterday it drained 12 percent in 30 mins.
Something else also happened yesterday. As it was almost going to die i plugged it into my car charger for about 10 mins. It was at 15% when i put it on and 19 when i took it off. After that my battery life was almost normal again as it only drained 4 percent over the next 3 hours. Later on that night I charged it back up to 50 percent and about 10 mins after taking it off the charger it said it was at 5 percent. It stayed at 5 percent for the rest of the night and did not die ( about 4 hours).
Theres definitely a problem and I know it was to do with the battery reading. I think i just need to reset the battery stats.
FYI every time i flash a new rom i always flash back to stock jf6, make sure its 100% battery, wipe data and cache, etc etc etc. so im not sure why this is happening.
I also tried wiping stats through clockworkmod recovery, but i dont think it really does anything.
The proper way to wipe battery stats/recalibrate your battery:
Charge up to 100% with the phone on. Disconnect the charger and turn the phone off. Connect the charger; you're now in charge mode. Charge up to 100%, disconnect the charger and turn on the phone. As soon as the phone is on, turn it off. Connect the charger to put it into charge mode again, and charge up to 100% again. Some people also say that before starting this process it's a good idea to kill the battery completely.
That is how you bump charge, or recalibrate the battery. After bump charging is the best time to wipe battery stats.
I can't find batterystats.bin on the phone to delete it. Is the only way via terminal mode or Clockwork?
I think there is a problem with my 3500 mah battery from sedio. I have had it for a few months now and it really wasnt what i expected. I had heard people who have had 2-3 days + battery life from one charge when i cant even get 24 hours on a single charge with out playing a game or using gps. Im running sky raiders 3.5 right now.
Is that bad? Should i try and get in contact with sedio? Any other tips.
Thanks in advance!
EDIT:
For example today:
13hrs since unplugged. 29%
awake 4.5 hours
That sucks right?

That is pretty bad. I'm at 12 hrs 50 mins since unplugged, 3 hrs 15 mins screen on, on stock battery. What kernel do you have?
Sent from my Droid Incredible running CM7 RC2.
I have to admit i am pretty new to all this stuff, just a couple of months in so i wouldnt know how to change my kernal but im sure i could figure it out if i had to.
Heres what i got:
There are all kinds of things you can do to extend your battery life but by far the simplest is to turn your screen down to quarter brightness and turn off the auto adjustment.
You need to reset your battery.
Step 1
charge the phone while turned off till the light turns green. Unplug but do not turn on then after about twenty or so seconds plug it back in and the light will be Orange again wait till its green.
Step 2
Once the charge light is green for a second time boot the phone into cwm and clear battery status. Make sure phone is still plugged in
Step 3
After you clear the batter status reboot the phone making sure that you do not unplug it . as soon as you're able to open up your app drawer once the phone has rebooted then unplug it.
Step 4
Do not charge your phone again until the battery dies and the phone shuts off.
After this you are done

For the longest time I was convinced the eBay-generic 3500mAH that came with the phone when I bought it online was faulty because it seemed I was getting identical results from my stock battery even after wiping battery stats. But now after running the battery for a week or so continuously and not swapping out to the stock battery it seems to yield much better life now that I calibrated the phone to this battery and left it in for a while.
The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance
Hello
Does your phone charge to fx 75% and after that doesnt get higher until after you restart the phone?

Yes excactly. But the numbers differs.
Today it charged to 100% though.
Got the same problem?
Sent from my Optimus 2X using XDA App
have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug
After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.
Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.
Best regards

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic
I know that but i am just saying that i also had the same problem with the stock rom.
Best regards

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

Recently I noticed sudden battery drain when 10% and below. It takes a couple of minutes while browsing or watching youtube battery goes down to 4% and then in a bout minutes goes down 1% and off. I am not sure when it started but my guess after JB 4.2 update. I am on three UK network.
Thanks

Don't know if it would help but you can try to calibrate the battery (actually the displaying of the percentage).
Charge your battery until it's full when the phone is on.
Disconnect it from charger.
Turn phone off.
Plug in charger and charge it until the LED turns green.
Disconnect charger, turn phone on and use it as usual (my desire needed a full discharging and charging cycle after that)

That's what I was thinking battery display might be off the rails a bit.
I will do it on the next charge then. Other than that battery does great job. 24h+

This exact same thing happened to me earlier today (ARHD 12.1). Very annoying. Is it a rom thing, or a battery calibration deal..?
i cant be sure, but it happened to me one time, so i use and app from playstore to calibrate the battery, and now it is ok,
Mine does the same thing, but it quickly goes from 5% to 1%. I assumed this was a normal feature to prevent the battery from draining completely, which is something you usually don't want to let happen. If that's the case though, HTC should have taken that last 5% into consideration when calibrating the battery.

I suggest you all should try that calibrating method and if that won't work, it's probably a defect of your phones

Has anyone else had any success at all with this
I'm running 4.3 GPE rom and I get excactly the same thing here, I don't think I had this before .... I've tried recalibrating the battery, doesn't make any difference, so frustrating.....
In your case I think it's just a calibration issue. I personally had the same issue with ARHD but it settled with 5-6 charging cycles.
There has been a difference of about 10-12% between TWRP and os battery percentage, running latest PN with EX kernel, the phone has also started to shutdown below 40 percent during last three weeks, have tried calibrating battery multiple times but the problem is still there, even factory reset my phone , has battery faulted after 2 and a half years of use? Or what could be the issue? Mind you the shut down happens only once and I don't have to connect the charge to turn it on, it always have 25-35% battery left
The battery itself is the issue. Replace it.
clear bootloader logs every time you charge the phone so it doesn't die at 40%, but yeah the battery is shot, need replacement

First... The info in TWRP is more correct because of how it is calculated...
Second... It's a voltage issue... Sign of a dying battery...
Repairsuniverse has a great video of how to replace it... Takes about an hour... Beware the volume and power ribbon... That connector is a bastard
