I am running Wang's latest 10.1 (4.2.2) ROM on this phone. I was using the video camera to record video. Once I stopped using it, I saw that it had 40% battery left. I turned off the display and put it in my pocket. I reached home and I can't turn it on, I removed the battery, put it back in, let it sit on the chager for half hour and tried to power it on. Nothing!
So, any ideas what happened to my phone? Did some chip just fry itself?
Any ideas folks?
ok. after one hour of charging, the phone turns on. I am so glad to get it back!
So, what the heck happened? It had 40% battery when I put it in my pocket. Is this a case of battery memory, where in it showed 40% but it had not charged till 100% to begin with and hence after 40%, it just fell to 0?
That might be the most probable cause.Try wiping battery stats from recovery and let the phone go through a couple of full charge-discharge cycles.
May the -Mass times Acceleration- be with you...

The last couple of days I've noticed something strange with my battery. I keep it on the charger all night and when I get up in the morning my phone says the battery is at 100% and the charge LED is green. The instant I pull my phone off the charger it drops a couple percent. I thought that was strange so this morning instead of pulling the phone off I just shut it down. Once the phone was completely off the LED went from Green to Orange as if it was charging again. It look another 20 minutes to turn green again. I powered the phone up and as soon as sense is loaded I am back to 93% battery.
Anyone else see this? I've wiped battery stats and did the whole calibration but that didn't seem to fix the issue.
That is normal... Once the batt hits 100%, the charger goes off and lets it drop to 95% or so and starts charging again. It does this to protect the battery. Also when you turn off, it will restart the charge.
The battery is lying, but that's not such a bad thing.

My battery has been acting up the last few days as well. As in, going from a full charge to ~35% in 3 hours and then down to ~12% an hour later. No new apps added, nothing out of the ordinary done. Regular uses and charging cycle. I normally reset my battery stats when I flash a new incarnation of a new ROM, but after a couple of days everything seems to be back to normal.
I've been baffled by this, but have yet to find the culprit. An app or searching for signal are my only thoughts.

This makes perfect sense, thank you for the link!
Ok I have searched and not found anything like this yet so I am going to ask. I know the phone has battery problems all around for a lot of people. Mine seems to be fine when it is on. It can sit and idle powered on all day locked and stay at full charge. It runs about 10 hours with minimal use and maybe 8 hours with some data use and a few calls and texts. Now I am experiencing a wired problem. When I go to work we cannot have cell phones. I leave my phone in my locker and power it off. After my 12 hour shift is up at work I come back to the phone with a dead battery? What could be causing this? And has anyone else noticed this issue?
defective battery? pull the battery and see if it still does it. If it does, gotta be a defective battery.. if it doesn't do it when pulled, you're not shutting off the phone maybe?
Yesterday I tried leaving the battery out. I took the battery out and let it sit 12 hours and it still had full charge when I put it back in. When I go to work I long press on the power/lock button and choose Power off then I watch it shut down and it just dies before I come back. I wish I could watch it the whole time. Today I left the phone off for around 6 hours and came back and it was fine though. Maybe it gets turned on some how at work. I have no idea. Or when I go to power it on it is just the issue where the phone isn't reading battery % correctly and it just says 0%
Seems like a battery driver issue or a defective battery? definitely call t-mobile and check if it's the battery. I've had some issues as well, but not that bad.
Weird.
So the phone powers off after you turn the screen on and it won't come back on? Try putting the phone in airplane mode.
Also, I'm assuming you are running the stock roms?
Might also want to check into a battery monitor to see if any 1 thing is pulling it down.
I think it might just be the battery driver. Sounds like the phone is in suspend so it doesn't power off properly until the screen is turned on and is revived, updating the battery % status, seeing 0%, and turning off.
CM7 fixed the wonky battery issue a few nights ago. Right now, I think a current CM based rom is the best bet as it has most of the drivers fixed. I'ved used mine pretty heavily today, unplugged at 8am and I just got a 15% battery warning at 11:30pm. It will usually last until I go to bed at midnight but I might want to play with it some more.
Well, this was interesting... Since day 1, I have had great battery life and have not experienced what everyone else has been experiencing.. An occassional lock-up/reboot, but nothing major.
A couple of weeks ago, I switched to a backup battery (andida). Things have been going well w/ that battery. Yesterday, I updated cwm.. While the andida battery was out, I decided to switch back to the stock battery for a while. Then, the following items took place all within a few hours of use, which I have not experienced.. ever before:
- Battery temp running high.. Andida constantly hanging around 22.2 - 23.2. Stock was hitting around 43 until i rebooted the phone, then dropped to 40. It is currently running at 36.
- 2 shutdowns. I could not boot the phone past the LG logo after the shutdown. Was able to boot into CWM though > went to shutdown > tried to boot, same thing. Had to pull the battery in order for it to boot.
- Received a phone call, answered, but the phone kept ringing during the entire phone conversation.
- 2 screen lockups. Could slide the unlock, get the haptic feedback, but that was it. It would not unlock. Had to reboot.
- 1 black screen of death? Total black screen with the task bar displayed. Was able to go into settings, pull down the task bar, etc. Background was blacked out. Reboot, fixed.
- Can not get gps. Was driving for 5min trying to get a GPS lock, nothing. Opened up GPS test and not a single satellite showed up in the list.
- Finally... and worst of all. Last night I plug in the phone for a couple of hours. As I'm going to bed, I disconnect the usb from it.. and take a glance to see where it charged to - 100%. I go to bed at around 1:30am. I wake up at 7:30a, turn on the screen of the phone, and it gives low battery warning. It's at 2%. I reboot the phone to make sure. It's at 1%.
So idk.. maybe something was stuck running. I'll find out here shortly after this charge is done.. but I am seeing a major difference in the operation of the phone after putting the stock battery back in. I had not experienced this when I was running the stock battery in the past. (I had an occasional lockup/reboot.. but not to this scale.. and I had always had fantastic battery life. Every single time I unplugged before bed and had 100%, I would have 98% when I woke up).
Suggestions? Changes were updating to the new CWM 4 and putting the stock battery back in. Running Bionix RC1..which I have been running for a while. I'll let this sucker charge up and see what it does. Maybe I should wipe the batt stats?
yeah wipe the batt stats. possibly try cm7 its really stable now. i know it doesnt have the a2dp but every else works. i would say another kernel also faux's or morific work fine. use setcpu if your going to oc. if you choose to flash another i would do a complete wipe of everything then install so hopefully the problems wont pop back up in the new flash. i read in one of the thread that if your battery is dated 3/2011 it will have issues but the 4/2011 or whatever will have less reboot and freezes issues may wanna try getting a replacement if you wanna stick with bionix until krylon does an update.
The andida battery doesn't have a temp sensor, so it's worthless for testing temperatures.
well, idk.. who knows what the crap happened. I charged to 79% and unplugged. 2.5hrs later, I'm still at 72%. That's around 3% an hr. Last night was 17%/hr.. Something happened last night.. Man, I'd love to know what took place.
Either I had an app going wild all night, or the battery really never charged.. and the 100% was deceptive. It's just nuts how all of these probs all of a sudden surfaced right after cwm 4 and putting the stock battery back in. They never surfaced b4 on the same ROM and with the same battery that I used for weeks and weeks.
O'well....

I know, it is just weird but it does happens from timr to time.
God bless you my brother in Christ
I see that you are a Jesus Freak just like me

When the battery is less than when it removed,After some time and putting it back will be full power display
SORRY FOR MY BAD ENGLISH
You should wipe battery stats when doing any major rom change (stock to custom or between different roms).
Battery will always be wonky the first time before a full charge/discharge on the rom unless it is 100% and battery stats are wiped.
Typically what I do (on CM7), is when I wake up the phone is at 100%. I download the latest nightly while I'm in the shower. Jump out, it starts to flash. When its done and booted up, I wipe stats then unplug the phone and go to work.
I don't always wipe stats. But with all of the battery tweaks and fixes he's done, I will occasionally.
I very rarely ever completely turn my phone off, but last night I decided to turn it off right before I went to sleep. My battery was down to 25% right before I turned it off. When I woke up this morning the phone would not turn on. So I decided to plug it into the wall charger to see if it would help. Well the phone did turn on after I plugged it in and to my surprise the battery was showing as 0% charged which is why it wouldn't turn on without being plugged in.
So, that means that something drained my battery from 25% to 0% while the phone was completely turned off. What in the world would be running while the phone is turned off that would drain the battery like that?
weird situation?
ok so yesturday i flashed over the new humble.
and well i left it charging iver night.
when i woke up my i disconnected the charger and took off.
when i checked my battery stat and what was using it.
my display was at 49%
i have never had it this low its always 75% and up.
and during the time.i had it down in the 40s. it hardly wasted any battery.
and now i restarted my phone and screen is back to 89% -.-
and i havent used it at all and ita been 4 hours and am down to 88% battery only with phon at idle in my pocket. ohh and i had data off..
wat is going on!?
You need to calibrate your battery. The easiest way to do it is to use the battery calibration app you can get from the Market. Put it on the charger and wait until it is 100%, and before you unplug it, run the calibration app and press the button. After it's done, take it off the charger. For best results, you need to then completely drain the phone without ever plugging it back in and then completely recharge it again without ever unplugging it. However, just doing the initial calibration will help you out a lot.
what do u mean the initial calibration?
and do u know why my display was really low? n stayed like that?
untill i rebooted
I hope I am in the right forum for this...
Lately my two year old tf700t won't stay on for more than 10 mins at a time. I have the dock and both parts say more than 100% charged.
Due to my device being out of warranty and thinking something was wrong with my stock asus rom. I downgraded the rom, rooted it, unlocked and tried several different roms.
My tablet is still turning off even though it says it is 100% charged.
Is my problem a bad battery? I think it has discharged "fully" (to where it warns me) maybe 10 times in the two years i've had it in the dock. It has almost always been plugged in or lightly used around the house. It has never been drained and recharged repeatedly to the point that I would have thought it to be worn out by now.
When I've had batteries go previously, they just drain fast from 100% to 0%. Both batteries are at 100% and it won't stay on but maybe 10 minutes unplugged. When I plug it in, it takes about 5-10 mins before it turns back on again. Meanwhile, the led by the power button blinks orange like the battery is dead. When it turns back on, it tells me I'm fully charged. grr
Does anyone know what is going on? Is there a way to test the battery or is there some chip inside the thing that needs to be reset or something.

It sounds like that you have a calibrations issue with your device. When your device is shut off by itself, you should leave it unplug about a day. Then recharge your device after a day of depletion and hope that it will solve your problem, good luck...:fingers-crossed:
Mhhhh - "almost always plugged in"?
Not the best use for these batteries. 2 years of that could have killed it.... And then - may not have anything to do with it if the battery went bad. 2 years is not an unreasonable life expectancy for a battery for a portable device.
In addition to LMK's suggestion, you could try this:
Let it die and then sit for a day unplugged.
Connect it via USB to your PC and let it trickle charge for 8+ hours (charging indicator will not even come on). Make sure your PC doesn't shut down or go into sleep mode during that time.
It should be charged enough to boot it. Check if it made a difference.
