So I have gone through the suggestions for improving battery life in this post and countless other sites (I have a Verizon Thunderbolt), I am on the fringe about rooting, but my battery is only lasting 4-6 hours (and not touching it again) and I am getting close to pulling the trigger. This actually only started in the last week or so, before I was getting 10-12 hours from it. One thing in particular seems to be bogging me down still: after downloading the update to Blockbuster and changing the auto update settings, the PVMtpServiceStart still seems to be using the most battery life (85%) EVEN though I force stopped the service. I check this in the About Phone - Battery Use, PVMtpServiceStart shows stopped but the % use on the battery is still the highest in the listed things.
Any suggestions on what else can I do here?
