Ok well..about a day ago my battery was about 5% left..so I put it on the charger...It ends up dieing so im like ok..and just left it to charge but it would not charge at all...then i thought it was my laptop so I tried the house charger the next day when i got home...that didn't work either so I work at a phone store and I got another battery it didn't charge either..so I got my boss to check it out for me and she took it apart nothing wrong on the inside and she put it back together so she restored it and I thought it worked but it didn't so now im confused of whats wrong...Im running the Energy GSM ROM and I would appreciate some help =D.
