Techniques for saving mobile device power during turn by turn navigation sessions are provided. An example method includes receiving an indication of an origin location and a destination location via a navigation application operating on a mobile computing device; generating a navigation route based on the origin location and the destination location using the navigation application, including indications of one or more maneuvers required to be performed by a user; comparing a remaining battery power level associated with the mobile computing device to a predicted processing power required for the navigation application to perform one or more functions related to the navigation route; and causing the navigation application to operate in a power-saving mode based on the comparison. Operating the navigation application in the power-saving mode may include temporarily suspending at least one of the one or more functions of related to the navigation route.
