It has actually now gone bad; I have two batteries, I charge and change since my usb is faulty. This afternoon, my battery died so I removed that one and put in another one which was fully charged by then. On restarting, the phone starts up as usual, nokia logo and the hands pass and after that, the phone stays on for like 5-10 seconds and goes off. After 15 seconds, it brings itself back on and this repeats over and over again. I can't really tell what went wrong, and it goes off so fast, before I even get to contents of Menu..... Confused and really confused, please advicee..
