 Not really sure that's evil.  The GSM unit is connected directly to
 battery... the charger rightly decided the battery was full and stopped
 charging, then the GSM unit is eating 10mA direct from battery.  I guess
 after some interval the charger will see if it should charge again.

 Yes it makes sense.
