To pick up on Andrew's point. The battery life we have seen on lower end
smartphones (Samsung Galaxy Pocket) deployed in the field (in Cebu in the
Philippines) when using GPS to send regular location traces to a server (not
OSM, but would be indicative of battery life of doing this) is 3-4 hrs
depending on conditions and intensity of use.
3-4 hours does seem a tad low - In my experience (Blackberry 9700)
continual GPS tracking would reduce the battery life (perhaps from 24
hours to 12), but not be anything like to that extent, and not anything
like as much as if I was keeping an eye on the football or cricket
scores. Maybe it's the "server access" part that brought life down to
3-4 hours?
How often the software's accessing the GPS (in OSM applications it's
going to be "hot" the whole time, in others perhaps not) and other
servers is going to be key - and obviously phones vary in terms of
battery life anyway - bigger/smaller screens, bigger/smaller batteries,
different OSes etc.
Cheers,
Andy
