hi,

I recently upgrade my iphone 4 with iOS6. After a week or so, I am having issues.

iPhone 4 will not boot up once battery drained completely . It shows itunes logo while charging.

I tried to restore couple of times through itunes , it works but once battery is drained, it again start showing itunes logo and asking to restore.

Can anybody shed some light. It's battery problem or other hardware issues.

Thanks in Advance.
