What is the athlete app's battery usage while tracking?

RunnerBeam is optimised for long tracking sessions and is designed to minimise battery usage.

On most recent iPhones, you can comfortably track an ultra marathon of up to around 20 hours on a single charge, depending on your device, battery health and settings. For longer races or multi-day events, we recommend carrying a small power bank or recharging your phone whenever possible to ensure uninterrupted live tracking.

We allow the distance between location updates to be configured per-event, to ensure that longer events don't drain the battery any more than necessary.
