Audiovox CDM 8910 Troubleshooting
No matter how long you have the phone plugged into a charger, once it is taken off the charger, the battery icon falls to one bar.
If the phone is unable to hold a charge, then the problem might be that the plastic charge port at the bottom of the phone is broken. The charger will not be able to connect to the charge port. In that case, the charge port will need to be replaced.
If you are able to use the phone while it is connected to the charger, but it turns off immediately after it is unplugged from the charger, then that is a sign that the phone has a dead battery. To see this repair guide go to Installing Audiovox CDM-8910 Battery
