One session and the battery is dead! If you wear it as a watch with the display always on (as most watches) it will last about a week.  IS THIS POSSIBLE?

Hi Philip,

Please contact us at info@gps-speedsurfing.com ,  normal battery time should be around 7 to 8 hours when logging GPS data. When switched over to watch mode (so not logging GPS) a week should be normal. When contacting us please provide also the order number and when you ordered.
