works for me. It's been unplugged for 15 minutes an only dropped 2% while I have been online. Before the on off trick 15 minutes would drop 12%...I never got the light to stay green right after turning off but it did get shorter to get fully charged while off.
Ok so I'm back an my battery level still sucks. This only worked last night. I did the same for my girls evo and left it unplugged and it ply dropped 4%. Considering my evo now is back to draining the battery quick. I have lost hope. I have done most of the tips every one Has suggested
