This is probably a no brainer, but I'm gonna ask it anyway. I listen to pandora while working, running the phone through a set of amplified computer speakers. I know the maxx battery can easily power the phone all day. The questions is, if the phone is sitting there next to a power outlet, should I plug it in with the charger or use the battery? I guess my concern is when I start the day and the phone is fully charged, it seems strange to plug it in again. On the other hand, I know a battery only has a certain number of discharges, so I'd like to do what will make it last the longest.
