I have been running an app called CharityMiles simultaneously with Cyclemeter on my iPhone 5c. Today's ride was 41 miles and I had 73% battery life left at the end of the ride. Total time of the ride, including stopped time, was 3:15:12. However, CharityMiles only uses the GPS and does not pair with any sensors.
