This is an ongoing problem. If my phone dies, and I don't charge it right away, the battery will not charge. It's as if the phone thinks the battery is "too dead" to charge. I have maybe a couple hours to get to a charger or else I have to "kick start" my phone (a term I made up.) Basically I have to take a battery that's not dead, plug it it and turn the phone on. Then I can swap out my other dead battery and charge that. For this very reason I have several batteries, except just recently all my battery's are dead, hence me trying to post about the problem again. I know its not the battery's fault because I have several and they all do the same thing. I know it all sounds very complicated, and its a real pain. I wish someone out there would know what's wrong with the phone.
