Dropped calls still regularly happen for people? I'm driving and on the phone fairly regularly and the last time I had a dropped call was when I went from the mall to the parking garage via the elevator two or three months ago.
My work location also causes my battery to drain almost twice as fast.
I'm in the dense suburbs with plenty of medium-sized businesses, and a few large business branches (FedEx has a warehoure house 2 blocks from here, and Enterprise admin offices are nearby), so I'm not in the sticks or anything, but also not the city proper.
