hi everyone.one of my friends has updated his i8510 but it's battery is still awful.i suggested him to update his phone again.he did it.and the battery was good for about 4 days but then again,the battery can't hold on for more than a year.
what should he do?is there a way?(by the way,the battery has no problems)
thanks
