Note: Continued use of GPS running in the background can dramatically decrease battery life. However iMi only uses location services when a workout is actually in progress. Live telemetry and route tracking rely on GPS, but location services can be turned off and still successfully use the interval functionality or any sensor-based functionality in iMobileIntervals.
