I just recently bought a phone off of ebay (it was listed as used, but the description is as follows: "CONDITION: This phone is in EXCELLENT MINT CONDITION. It came to us as a part of a factory overstock lot. There is no box or manual but the phone itself is in MINT CONDITION. The phone has been fully tested and is in 100% working condition. The phone has a clear ESN and is ready for activation on the VERIZON Wireless Network...Guaranteed!!! " I plugged my phone into the charger the moment I got it and let it sit for about 5 hours. When I next looked at it it said that charging was complete. But, whenever I try to take it off the charger it "dies" and will not turn back on unless I plug it back into the charger.
