So I tested my battery for the past 5 days and here are the results: I charged my battery to 100% each night before bed. The first two nights the phone was NOT JB. After 8 hour so standby time and 3 min of usage I had 99% battery life when I woke up. Both nights didn't pass 3 in of usage. After JB on Tuesday and installing the following apps (bitesms, sbsettngs, my3g and shrink) I know wake up with 93% battery with 40 min of usage and 8 hours of standby. I turned everything off just like how it was before I JBing. The phone was set up the same exact way each night. I guess my questions is where is the difference coming from between the 3min of usage to 40 min of usage over night while I'm sleeping. I was fine with 3 min even though I didn't touch the phone once I unplugged it from the charger, but 40 min is pretty steep IMO.
