How long will the battery last on raceday?
This depends on both the age of your phone, the starting condition of the battery, and your usage of the phone during race-time. Please read our Power Optimization Strategies for race-day. A brand new phone will deliver roughly 4 hours of broadcast time. You may also opt to purchase an external battery pack for your phone, which can effectively double the uptime of your device. We highly recommend that you do a long training run with the app running to get a feel for your device’s specific performance. If you opt not to use an external battery booster, you may wish to only use the app for the first half or the last half of the marathon. We’ve compiled a list of hard-won Power Optimization Strategies for you to follow in order to maximize the battery life of your smartphone on raceday.
