Went to charge my 710 last week and nothing happened. Bought a new battery and that worked through a few charges. Last night it lost all charge and I tried to recharge but phone would not charge. This morning I read that if I connected through USB to computer that might help and it did. Was able to charge battery fully. Has anyone experienced this? Just wondering if I should do a hard reset and wipe the phone or is it a hardware problem with the charging mechanism?
