This post is just as a brief update to comment on today's use. This is the first time that I've used the GPS all day as my principle mapping and GPS device. We walked for a little under 18 miles in around 8 hours. The battery was freshly charged before setting off and at the end of the hike it was down to 69% charge. That implies it might mange 24 hours. I checked the route occasionally but I must confess that I know much of the route from memory and so the screen wasn't activated very often. The GPS was being repeatedly activated by a helper app but the phone was in 'airplane mode' to disable 3G and WiFi sections.

The screenshot gives an indication of the GPS accuracy. The wooded section in the Haddon Hall estate just east of Bakewell has substantial tree cover and the contours are such that it is in a gulley. This is as good as one could expect from a retail GPS unit.
The sun was mostly screened by mist although I'd classify the day as 'bright'. The screen was readable throughout.
