ever since i had my iphone, ive had batter metter problems. first i would notice the batter metter jumping 10-15% when i plug it in and now it doesnt how the progress of charging. ive done a complete virginiz from 1.1.2 to 1.1.1 and same thing. if i turn off my phone it will show what it charge. ive tried to almost drained the battery my having everything on. it got to where the phone wouldnt turn on completely unless u charge. and recharge and same thing. im updating back to 1.1.2 and going to see if that works. can the battery be completely drained? i dont know if anyone has had this problem. im unlocked and and with tmobile usa if that helps. thanks for any advice.
