The app uses some battery, mainly for the screen and GPS. By default our app dims the screen between cues, so you should be able to easily get a full days outdoor navigation with a fully charged battery. If you are concerned about battery live, you can conserve battery by taking the following steps:
Use a dedicated navigation smartphone and turn cellular data off while riding.
Keep the screen off as much as possible when not in use.
Turn off other apps.
Reduce maximum screen brightness.
Charge your phone whenever you have access to an outlet.
Bring a portable cell phone power bank to recharge your phone on the go.
