I would confirm that the chart datum is the same as the BB/gps. If the BB can't match datum, the position is at least a little bit wrong. Imagine being a little bit aground. And yes the BB will consume a fair amount of battery over the course of a day.
My non-BB phone, a Casio ruggedized phone (GZ-one) on Verizon, claims GPS ability, but I have determined that it is not actually GPS... It is RDF, using the cell towers for triangulation... Which is OK, in range of a cell tower I suppose... not sure of the location precision... But there are a lot of places on L. O. where I am out of tower range. No tower, no position data. Ever try to make a call from Main Duck island? Something to keep in mind.
