The OtoZen app has one of the lowest battery consumptions compared to several other apps that use location services. The OtoZen's Pod sensors determine when a trip starts and "wake" up the app, and until such time the app consumes minimal battery power. OtoZen Pod and OtoZen app work to make sure the GPS services are requested only when you are on a trip.
Most users should expect about 5% of battery power consumed for a 1-hour trip. This amount can vary depending on how often you have the app open during the trip, the phone type, and battery capacity.
We are constantly working to improve battery usage, so please make sure you have the newest version of the app.
