My daughter has an Extrovert 2. We purchased a new LG battery (brand new, LG brand), but it won't keep the charge. We plug it into the charger. The phone's display reads "Battery fully charged. Unplug to conserve energy." As soon as we unplug the phone from the charger, it dies. I've gone through the troubleshooting steps and they've not helped. Additionally, we taken the battery out multiple times and that's not "fixed" it either. This phone has not been in water or condensation and was working fine up until the time the battery was replaced. The phone does still send and receive text messages, as long as it's plugged in. We have tried the original charger, as well as another charger that has been used successfully in the past to charge this phone. There isn't a memory card in the phone to "interfere" with the operation of the phone. NOTE: The battery was replaced because it was dropped, losing the battery in the process.
