#505 Invalid interpretation of battery status for Sharp GX15

[rodhan]

FMA connects successfully to my Sharp GX15 through
Bluetooth but aborts because it thinks the battery is
too low.

From the debug log:

...
14:06:43:930 Retrieve Signal and Battery Status
14:06:44:008 [TX] AT+CBC
14:06:44:305 [RX] +CBC: 2,0
14:06:44:320 Battery is too low... Going to Offline mode...
14:06:44:336 Abort called
14:06:44:336 [RX] OK
...

The handset seems to return "+CBC: 2,0" whether the
battery is full, half-full or empty, or whether it is
on AC power or not.

The phone is identified as a SHARP GX Mdm 4:
