I bought a new genuine Nokia battery but it didn't make any difference. The most annoying thing is that it stopped charging from anything but the factory charger. I can't charge in the car (unless I use an inverter with the factory charger) or from a USB port any more. Mine came out of the reboot cycle after I took the battery out and left it out for a long time a couple of times. After a bunch of attempts it finally booted with the charger plugged in. It was really scary because the battery was almost dead and every time I plugged in the charger it immediately went into the reboot loop. I now have a spare battery...
