The Strava iOS app relies upon on-location services, which require extra battery power beyond what would be used when the phone is in standby mode.
There are some things to keep in mind that can reduce the battery's discharge rate while running Strava. As a general guideline, we have observed modern phones successfully recording more than 5 hours of activity.
Old devices have old batteries
Older phones have two factors that contribute to poor battery performance. First, as batteries get repeatedly charged and discharged, their capacity slowly decreases. So a phone that has been recharged a few hundred times will perform worse than when it was new. Second, battery density continues to improve with technological advancement so a modern phone will have better performance potential than an older model.
In general, the idea is to turn off parts of the phone that are not necessary during your ride. By adjusting settings, you can turn off applications and functions so the phone will have more battery power to run Strava for a longer period of time. Don't forget to reset the changes you make to your phone's settings.
- Mobile devices use backlights or LEDs to create the light shown by their displays. These lights use a large amount of energy, so you should minimize or avoid the use of the screen while recording a very long activity. Turning off the phone's screen is the best way to prolong the duration of battery life.
Here is a list of wireless networking protocols that can be disabled if they're unnecessary:
- Push notifications
- Email sync and periodic message retrieval
Strava Beacon and Strava Live Segments require cellular data so these features will not work in airplane mode and could contribute to battery drain. Consider disabling these features if you're hoping to conserve battery.
