Hello guys, i already did search for this but haven't been able solve it. My phone is a new bootrom 3gs, running 3.1.3. Spirit JB. The thing is, the phone usage time is rising while its locked, almost 25 minutes per hour. Push is off, fetch manually, bluetooth off, location off, wifi off, etc etc.. only 3g is on, but turning it off doesn't make much difference. Don't know what else to do, battery goes very fast with minimum usage. thanks !
