I just bought an LG Optimus Showtime through Straight Talk (good phone). Nothings wrong with it just I think it maybe a glitch or something. It'll charge up to 99% & continue to charge... I don't know it maybe just an app making the phone do it. Any ideas on what to do?
Perhaps the battery isn't calibrated correctly, so it's appearing to be on 99% when maybe it's on say 73% and still obviously needs charged. Leave it charging on 99% overnight and see if this corrects it.
