FYI: I am finding that the radio switches off at the 15% battery level, so if you are at the 20% mark you had better recharge it if you want the phone to keep working.

10%.....

im on 5% right now and my radio is still on... 8700c

Interesting.

5 %

still on now at 5%, did not touch the radio, 8700c

I'm getting the same behaviour as gadgetman, 15% and it shuts off.

Yes mine too goes off at 15%....

mine shuts off at 15% as well... any settings unique to you 5%ers that you could share?

I have never paid attention to how much battery I have left when the radio shuts off. I am going to have to do that next time and see.
