I was flashing my Xperia T with flash tool and there was an error. Now I can't turn on my phone. The red led is blinking while trying to power it on. Vol up + power on also doesn't work (red led blinkinking). When connecting to pc flashtool stops on "For 2011 devices line, be sure you are not in MTP mode". What can I do?
First try to charge it for a few hours to see if it comes back, then you can try to repair via PC Companion or flash again

Already tried that and it's the same.
Yur battery is empty. You need to recharge. So open phone take battery out and charge it external. When battery is full just flash normal.
That is the reason why you should only flash if battery > 50%

He has a T so the battery is not removable....(Not without difficulty anyway)
Just leave it plugged in for several hours, or even better overnight. That should do it, and if it does not, then try and remove the battery
Now the red led is switching on/off every few minutes while on charger.
Just leave it it will boot soon

I have opened the back cover, disconnected the battery and after few minutes i have put the phone on charging. Red light appeard but after a while it went off again so i have measured the voltage. It's going from around 3.08V (red led off) to about 3.25V (red led on) and after that point red led is off, the battery is discharging and the process starts again. What can I do?
when did you do this?
Did you follow the advice above? In all cases I have heard of this leaving the phone on charge for 24 hours has fixed it. Plug it in, leave it alone, come back tomorrow and try to turn it on. (Maybe even hole power and volume up together untill it vibrates 3 times and then turn on)
Yes, I was charging it more than 24h and it was the same. I think I need to charge the battery external.
give it a go, and if you have the battery off you may even try and change it.
Thats what i told you. You cannot leave it charging. Chargemon is a software which can only start idf ROM is ok.
Just takr out battery and buy a cheap chinese external charger. I know R has builtin battery but it is no problem at all.
You REALLY have to charge it with external charger or another Phone with working software

I am not new to the phone and I have done battery calibrations many times. I used MIUI for a long time, then went to Pinnacle 1.1. After a few weeks one night after fully charging, I unplugged the charger and it dropped to 70% instantly. I could then plug the charger back in and it will not move from 70% for a while, then it will register 'fully charged'. Removal of the charger again will make it drop to 70%. Turning off the device and charging will show the green battery about 2/3 full, but not registering full. I then went back to MIUI thinking it was a rom flaw, but this problem has persisted. I am right now charging on stock JF6 with the same results. If this is indicative of a defective battery, has anyone seen this before? The battery is 14 months old.
TL;DR - It seems that the battery wont charge past 70% regardless of ROM/Kernel.
I had a similar problem but it was because I wasn't using the charger that comes with the phone switched chargers problem was solved.

I drained the battery last night, and then charged while off fully. The green battery icon went to 100%, and as soon as I turned it on it said 73%.
You might want to check into getting a new battery I got a extended battery for 10$ you can probably find the original sized battery for about the same price if you look around.

Google "bump charging". I had a similar issue when I was on serendipity vii, it would charge to full, but as soon as I unplugged it would drop to 80%. I bump charged, then calibrated. All was well after that.

Tried that. It hangs at about the 2/3 full level on the large green battery icon when the phone is charging off so I really can't do a proper bump charge.
I think I am going to resign to it being a battery past its prime...

I find that hard to believe, but it can't hurt to try!
Sounds like you need a battery calibration..
1. discharge completely
2. plug into a USB port on the computer for a slow charge up to 100% (overnight while "off")
3. unplug the device and turn it on
4. if you have a ROM with CWM installed, clear the battery stats at this time.
5. plug it into usb until it's charged to 100% (while on)
6. unplug the device and turn it off
7. plug in into usb again until its charged to 100%(while "off")
8. turn it on and use it as normal
This will allow the device to relearn it's battery charging characteristics. This is the battery calibration.

You are not leaving it long enough. It will reach 100% once it charges what it believes is 30% more. It must be off and you must clear the Batt stats.
Once it stops charging it marks that as fully charged. Your battery needs calibration.

You are right.
I did a small test with a coworkers battery today.
His battery in his phone - 88%
His battery in my phone - 58%
Leaves a delta of 30% which is exactly why mine stops charging at 70%.
It has gotten to 100% while off charging in the green. I then booted to CWM recovery and wiped battery stats, but it turns on at 70% again. It is almost like it isn't deleting the file.

It's true, go to your nearest AT&T store and tell them about your issue and they'll take your information (name, address etc...) and ship you a brand new OEM (Samsung) battery no questions asked. No idea why they don't just hand you one on the spot, but it only takes a few days to get to you anyways.

did you finish the procedure I mentioned? There is a calibration procedure. It involves turning it on and off several times and plugging it in an unplugging it several times.

I followed the calibration instructions perfectly. I have done it quite often actually. Didn't work. It acts as if CWM isn't actually deleting the file.
Deleted batterystats.bin via a terminal emulator and still no luck.

Hi
I'm new and this is my first thread.
After I rooted my phone I have an issue with charging my battery.
When I started the phone after the root I had a 100% battery, after I was playing and using it I plugged it in when I was going sleep.
After the whole night my phone charged from around 12% to only 60%, and then after I was using and draining the battery nearly to minimum(around 5-7%) it and left it for a couple o hours and it charged to 59%. Sometimes it charges a bit more but the whole process is really slow comparing it to the stock rom charging(it was taking lik 3-5 hours from 0-100%).
I rooted my phone with ivendor's rom from this thread:
http://forum.xda-developers.com/showthread.php?t=1825260
I was using CWM 6.0.1.2.
I would like to ask for any solutions for my problem, for now I want to drain it to 0 and then leave it again charging for a couple of hour maybe a whole night.
It's a bug. Sometimes is occures and sometimes not.
You could flash castagnaIT kernel and try again.
Just installed the kernel.
1st thing I noticed is a performance increase.
I'll gonna post what's the situation of battery tomorrow.
Ok, After a whole night of charging my phone only got to 68%, then when I was charging it when it was turned off It charged to 85% and when I turned it on it stopped to charge even with the AC plugged in and the icon is showing that it's charging.
Any solutions ? Please help.

I get a similar issue. When on stock I was always getting 100 %. Then I flashed CM9 and I randomly get 100 % after all night recharge.
If you are not afraid of switching ROMs, try a different one and let us know if it solved the problem because as mrjraider said
It's a bug.

Ok.
I was charging it turned off. It charged to 100%. I'll gonna test it today one more time with charging it when the phone is switched on.
If it fails I'll gonna get back to my stock rom and test it and try again with a battery charge to 100%.
Also remember that the phone wont charge completly due to safety of your battery..
Most of the time it recharged to 98 percent

Yes I know but the indicator in the phone 'has that in mind' so it shows 100% but its really 98 i know. When I was analyzing that battery graph I saw that the battery is charging really long. If I'm reading it right it takes the same amount of time to charge it as to drain it when using it.
Screen is attached. I was charging it through the wall charger.
It's polish language
Any opinions ?
Make your battery empty 0% !
Try to turn on the phone after empty battery !
and make sure that the battery is empty ....
Just connect your charger without turn on you phone....
charge your phone for 9 hours !
Then , take the charger out and turn on your phone !
Try... this steps may it help you

I think that the solution was USB debugging. When I turned it off the phone is normally charging full and works perfectly.

88% full charged battery
Hi, is someone solve this problem. On my alcatel idol 6030X with off phone battery is 100% changed, after power on show 88%. When charging with power on phone, after 88% charging stop. What to do?
Yesterday my phone shutted because my battery, I connected to my car and charged a while, I got out from charging and using 2-3 minutes more and battery died again. When I got home I connected it to AC power and powered on, It was working without problem. I left my phone maybe 1 hour charging and when I took it again it was dead: screen dead, no life signal, just the led blinking slowly when connected to power (either AC and USB)...tried to take off battery but nothing. Today I connected it to PC and windows has recognized it but cannot identify it (on the PC the classic USB device not recognized error with yellow triangle on top) and the led is always blinking.
Any idea? should I have to buy a new phone?
thanks

Try Running some POST tests. As in, Power off your device and wait for few seconds. Then Press and hold your power key and your volume down key. You should be able to access your Bootloader. (If you have Rooted your device, you could access your recovery and clear the battery stats although your device's condition seems peculiar/critical). Its worth a shot If you ask me.
I have already tried it but nothing, cleared dalvik and battery stats..I cannot understand whats going on. Now phone is working again but it cannot maintain battery, I mean I kept it in charge all the night but when I power on the phone it shuts down just when it starts android (thats strange because I went to a store yestarday and tried a new battery but it didn't worked, when got home I tried to power on it again and it started)...this is driving me crazy!!
edit: I turned it on, plugged in AC charger and phone after some minutes told me that (I don't remember the exact message) power needed by the phone is more than the charger could provide...
edit2: now it is on and it is charging (USB) and it doesn't charge more than 21%...really strange
Odd that this hasn't been mentioned but perhaps try a different usb cable? Different port? Seems obvious but you never know. Cables can deteriorate.

What do you think about?
Hello.
I've left my phone in the hot sun for some time and it's not working anymore. When I try to power it on, the LG logo appears and screen+buttons flash continnously as if it's struggling to start but can't. *this is on battery, not plugged it.
When I plug it in charger It powers up, everything is working but it eventually reboots by itself. Sometimes it stays on 3 seconds, other times 2-3 mins, then reboots.
I've tryed wipe data/factory reset, wipe dalvik cache, reinstall ROM, wipe battery stats..nothing works.
So basically if I plug out the charger it instantly shuts down and starts trying to power up in a continnous loop.
Is the battery dead?
Thanks
I think so... You could try another battery but it is possible that you may have fried some guts as well. Was it on when you cooked it in the sun?

Already tried a different battery? Its quite cheap and I guess some power cells might have died and that would explain the malfunction, when you "stress" the phone and it needs more power. Maybe it is able to deal with low power, but high output simply takes it down.

I didn't buy a battery yet because I can't find one. I'm on vacation (Italy) and at the local phone service they told me they don't know this phone and asked me where it's from :laugh:. and if I want a battery they have to order it and it takes time.
That's why I came here, hoping for a nice "custom" solution for the problem.
I think the battery does not know how to charge anymore, anyone knows a good clean wipe/format for the battery? besides discharge it complety and wipe stats.(because I cannot discharge it, when it's plugged in it says 100% and if I plug out the charger it dies)
thanks for the replies mates.

Hi Guys,
I have a rooted Xperia V with the original 1.140 -Version.
Since a month I do have the problem, that the phone turns off, at 5-8%.
My battery monitor widget, which I have since the first day of the Phone, shows me: 0% at 3010mV
But it turns of at 3400-3500mV.
I tried about 10times in a row to fully unload the phone and then a full recharge. But it didnt helped.
I deleted the batterystatsbin. Didnt helped.
I remember from my old Defy with CWM, that there was a point in recoverymode which allowed me to wipe my battery.
I would like to do that, but I dont get into recovery mode.
Volume + and power didnt helped, volume - puts me in safe mode, like windows safemode.
Can somebody help me to get clean batterystats again?
plz? :fingers-crossed:
Wiping batterystats has nothing to do with calibrating battery, it just wipes the stats shown under Settings - Power - Battery.
You should search for how to calibrate battery, there are several options available here on XDA.

My best advice is to let phone discharge so it dies by itself, then fully charge it to 100% without any powering on under charge process. When charged to 100 - turn on phone and let it charge additional 1 hour so it can add back the lost procentage values that was lost during boot up..

I followed your instructions. After that I let the phone discharge so it dies by itself. Same problem... 7% at 3208mV and it dies.
Furthermore theres a new "problem". As it charges while it turned off, the battery-icon wasnt fully loaded, it has a space between fully loaded and the acutal status. The green LED was on, as it does by 90%. After half an hour nothing changes, I turned on the phone, charger still plugged in, and it showed 99%. With this status it loaded 10-20min till it has 100%.
After some minutes, it might be 15, I removed the charger and used the phone normaly.
So it was an uninterrupting loading time of nearly 4h to 100%. But normaly it takes only 2:30h from 0%-100% with the 1760mAh Battery and the original 1500mAh-Charger.
Now the funny fact:
Normaly I have till now 70% Battery left. I do have at the moment 86%.
I dont get it...
