Drone battery vs controller battery

[jfo]

As I beginner I realized today it doesn't matter how many drone batteries you have. I was still on my 1st 30 min battery and the controller battery went dead. There's no batteries to swap out there, you just have to wait and recharge. What am I missing here? I have 3 drone batteries but the controller runs out of power 1st.

That's weird, on both my M1P and M2P I can do approximately 4 batteries till the RC is depleted. Anyway, an easy solution (which I use when I need to fly more batteries) is to connect your phone using the bottom USB cable and connect the RC to a powerbank through the top-left miniUSB port. That way you are no longer limited by your RC battery life.
