I have a Motorola HD Razr Max, battery is incredible even using GPS and
Bluetooth.  Diane has a Moto X, battery sucks.  Mine has a nice charging
station that works essentially like a clock radio, giving time,
temperature, calendar and more.  I think it cost $10 and I have 2 of them,
one downstairs and the other next to the bed.  I can use mine full tilt and
after a full day will still have 87% in the battery.
