What do you mean plugging battery out??

plugging battery out by opening the back panel , and removing it from the board socket

Are you using stock charger to charge online? there might be one more possibility that battery might not be pinned properly to the phone.

yes i am using stock charger , and i tried several times battery is pinned properly .. it all started because the computer guy made wrong usb connections on my computers motherboard .. i connected to transfer my photos and it suddenly died. on connecting to computer via usb it charges sometimes ..but then restarting it results in mega drop in battery level and then it wont charge.

Just wanted to know that if this is a hardware issue or a software issue. would flashing a ftf solve the issue ?

K i personally think that there is a problem with the battery. once the battery is connected to wrong polarity it generally get ****ed up but i see that it charges properly with the battery charger. if the charge is retained normally there is definitely no problem in battery. It will be the PIN . But not harm in trying to reset through PCC or flashing FTF.

ok i will check one thing tonight .. am gonna charge the battery and leave it over night .. if charge retains and acts normal i guess pin and everything else has to be fine .. then the only thing fishy would be when connecting a charger...

Does Kernel affects charging or mess it up ??

Yea it does. Get back to stock charge your battery use the phone. if the battery drains normally. There is no problem with battery. The problem is with pin configuration of the phone.

am on stock and i charged it .. and battery seems to act a little funny with the drops ... restarting results in 2% loss and it went from 55% to 47% in few minutes on idle state ..

also the phone doesnt turn off .. it would just restart itself ....

so guys any help if it is the battery issue or something with software also should i try this

i flashed a ftf in flashmode ... still battery would charge just 1% from its current level like it would go to 19% from 18% and stop there ...on connecting to usb or stock charger ...and battery level would drop crazy after that on restarting ..

also phone would be in turn off mode it would just restart ,,,


should i buy a new battery ??

If you are under warranty its better to take it to service. If not change you battery and charger

Not under warranty and i did went to sony service center they said we do not repair .. however sony could swap and i have to pay for a new phone and pay 80% of its cost :/


i ordered a new battery .. changing the charger is important as well ??

I'm not sure its safer to check it with the new charger first in order to avoid Any problem. Other wise you can check the charger with some other phone
