Re: >So Mr Average uses his smart phone as an Alarm clock and map.
As I took an unexpected trip on Sunday (borrowed a van to shift a sofa) I realised that I'd charged my wife's phone the night before, so the battery was low (~30%).
Since it was my GPS and my comms system I had to take a decision on whether to head home first (pain, and the collection was time limited)... I didn't.
I just turned the screen off for the journey - prodded it on at the approach to junctions that looked complex. Made it back home with >20% battery.
Seriously battery life on a device that is sensibly used has come a long way in the last few years...
