# How long will the battery last?

In passive or standby mode it should last for several days. When in activity tracking, assistance or alerting mode, the device will be carrying out per second tracking with network communications every minute, which will significantly reduce the battery life. It will typically last approximately 7 hours in one of the tracking modes.
