Going up...up...up......

I was @ 65ft when I lost connection. Do y’all think Tello just kept climbing or did it come to a halt and battery went dead........... My display showed 65ft when I lost WiFi connection. In the morning, I’ll go check around for the dead Tello. If it died while hovering, I guess it just fluttered back down to earth close to where I launched from.......

When Tello not receive any command within 15 seconds OR its battery reach ~9% capacity, it will automatically landing.
at least this is behavior I seen from my experience using Tello for the last 6 months.
