I really love Nokia Sports Tracker application and personally this is one the main reasons for me to choose Nokia device and S60 platform. What I have tested in the last few days is impressive battery performance of E71 and GPS tracking.
This week I have tracked two of my bike rides taking 5-6 hours each. At the same time the phone was used for listening FM radio or playing mp3 files. Moreover, in rural area the phone had poor GSM signal strength, which also has impact on energy consumption. Result? Very good! Fully charged device lost only 3 or 4 battery’s indicator bars after such a trial. In comparison to known poor battery performance of devices like N95, or used previously N80 with external LD-4W – no more than 4 hrs this is it! I know that E71 is a rather business oriented product but I’m sure that every Sports Tracker fan will like this pair.
Here you can find one of GPS tracks published on Nokia Sports Tracker page.
P.S. Please remember that current NST’ version encounters problem with freezing on a main screen. Workaround hint was posted in here before.
