Battery issue with v21a?

Hey all, thanks to the dark lestat for his incredible kitchen rom for this lg thrill. I charged my lg thrill yesterday in the morning and then when I got home it was hot. Ever since that my battery life has been going down like mad fast so I'm wondering is my battery dead? I charged it using a different charger which I shouldn't have but it's a ipod wall plug which should have stopped charging if it's full. As soon as I found out it was hot I turned it off immediately and let it cool.
I turned it on from 6pm to now and the battery is at 49% where as before it was like maybe 85% left. I have wifi on constantly, and the live wallpaper but it shouldn't be down that fast. I also have facebook notification on but I don't use the phone at all, just standby mode. Could my battery be "dead" ?
when i was dawnlodeng some game from gameloft i went away some time and came back to find the battry so hot and masseg on the phone says( battry overheted and chareg disconect) so i unblgd the battry for 3-4h and put it back and i feel like my battry empty fast>>>without using it work like 24h (syngmail facbook notf. on and life wall)but if i just use the music player for 2h it become(from 100 to 66),a frind of mine told me that it is battry normal to empty fast using wifi or 3d>>>like iphone when i use wifi it empty fast.
what u think

(Q) note charged itself over night ...?!

I was using the phone for about 2.5h with wifi on browsing reading some news and got the battery to 38%. Then I have activated the power saving option and locked the screen and went to bed. Now I just woke up and see that my battery is at41% wow. Did it charged up or what has happened?
An inaccuracy of the battery meter? It defenitely did not charge itself. That's physically and chemically impossible.

It's weird how it constantly increased from 38-41 it was not just a sudden jump... I got sudden drops in battery after a usual reboot, and but never a slow increase....

Actually yes it does happen.. I really can't pinpoint the reason though.. After heavy usage the battery does drain for a while after the usage and then since no usage some power is restored.. Same like AA batteries.. Example: Use AA batteries on a device till the device switches off.. Then leave the device idle for a while and battery will be usable for sometime though the device had switched off earlier due to complete drain..
I'm not an electronics person. So i dunno how or what makes this happen :silly:

Sudden battery drain when at 10% and below

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+
I get this aswell, on android revolution 12. It goes from 8% down to 1% and bam my phone is off. Really annoying

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.

Same issues here

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.

[Q] My 1 year old Nook's battery (stats) is doing weird stuff

So I've never had a problem with my battery at all. I easily got 6h of screen on time and everything was great.
Recently my Nook started to randomly shut off at around 20-30 %. It "popped" and it was off. Didn't reboot either. Like the battery was dead.
I would have to charge it again to be able to power it on.
Also the stats seemed to be off. The lockscreen sometimes told me it's fully charged and whenever I unplugged my Nook it wasn't fully charged. The battery LED also sometimes flashes green/red during charging.
I only get around 2-3 h of SOT at the moment.
I tried reflashing a couple of times (with full wipes) but the problem occured again.
So my question is: Are my battery stats messed up? Does it just stop charging at a certain point because it thinks it's fully charged but it isn't in reality?
Any ideas (on how to fix this)?

It's almost sure that you battery is degrading very fast. But its my advice to re-calibrate your battery. Set your screen brightness to max setting and leave it on until it shuts down. Now don't power it on. Leave it charging for around 2 and half hour.
Now install geekbench benchmark app and test your battery.
If you heard a pop noise, the battery probably delaminated/micro-exploded. (Li-Ion's tend to swell and fail from the heat of (over)charging.)
There's a company, newpower99.com, who has a YouTube video on replacing the battery in the HD+. The battery sold for $25 US last year, but now that our batteries are beginning to degrade, they're out of stock.
I found another site selling replacement batteries for $80. (portatronics.com)
I've noticed that my screen-on time has dropped from 6 hous to 5.5. Maybe the Nokia N1 will be available and rooted by the time I hit 3 hours.

I'm having the same issues, and reading this reminded me of trying BatteryCalibration to reset the battery since my nook HD+ stock OS is rooted.
I had this problem several times before I installed CM. Usually, it happened when there was an update available, and when the Nook started to update, it factory reset itself.

difference between TWRP and os battery percentage?

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
