Details

When battery voltage drops under battery_level_shutoff (about 1-10mV - it depends from round off), device estimated runtime loops over unsigned int range and displays 35 millions hours left instead of zero. It can be noticed when using battery benchmark or System->Rockbox info->Battery.

I've added voltage range checking, so that bug is now fixed. I've tested it (i.e. by modifying values in /firmware/target/.../powermgmt-c200.c) and works OK.

example battery benchmark files, that shows issue (look at the end of the file):
