The short answer: 1-3 days, but it depends on how the tracker is used.

Basically the Qbit is a technological miracle.  The Qbit is what you get if the world’s smallest cell phone and tiniest GPS tracker had a baby.  The 450 mAh battery is pretty small, so here are some tips on how to make it last.

• Use Live Audio and two-way voice features sparingly.  Voice features will reduce the battery life substantially.
• Use GPS reporting only when you need it.  You can enable or disable GPS reporting from the app.  Go to Commands  > New > Turn off GPS reporting. You can still use the Get Google Maps Link to get the exact location when needed.
• Keep the Qbit indoors. Like all batteries, the Qbit’s battery is affected by extremely cold temperatures.
