Speaking of battery drain, it is very true. Regardless of type, iphone
vs android phone or tablet, battery life is greatly reduced with
ongoing GPS use. On Amazon.com, i searched for solar cell phone
chargers and for less than $30, I got a small solar charger that is
the dimensions as the phone itself. While not strong enought to power
the device fully if it's battery is fully discharged, it will greatly
extend it's life. It also has a built in battry that can hold a
charge so it can be plugged in to provide power and recharge the
phone's battery. Would hate to land out, and find there's not enough
battery left in the phone to make the call for a retrieve.
