Recently my DX has taken to refusing to charge the stock Motorola battery that came with it. It has been working for 8 months, but suddenly started giving an "Invalid Battery" message when the charger is plugged in. I have to put the battery into the external charger to charg it and then place it back in the phone when it is charged. This is a PITA.
What would cause this and is there a cure?
