Well to me there is nothing easy about activating the Droid. Pressing the button on top with index finger, repositioning the phone in your hand to then the swipe or pattern... It's just not an easy one hand series of moves IMO. Other than that accessing FreeCaddie is easy, however you will have to turn GPS on and off separately(It is not inter grated to remind you or activate through app.) You can get a full round in with a full charge. It depends how bright you have the screen and how often you look at it. Have a charger handy after wards though. I will say that I installed on my golf cart a 12 volt converter that utilizes all 36 volts to produce 12 volt for lights and radio and for some reason the phone acts very buggy when using touch while on charge. The radio I have has a USB and i get the same bugs. Same charger works fine in car and I tried other chargers. Having said all that... Last night I turned off sync, wifi, location/GPS and let the phone charge to 100%. Wake up 6 hours later to find that battery is at 60% and 40% of usage was phone idle??? Weather channel runs in notification, I wonder if it somehow drains it.
