I just discovered that you can charge you phone/tablet from you controller. Great feature on the Mini 2 that is not available on the Mini 1. Saved me many times because my phone (iPhone 8) runs out of battery long before the controller (or my 4 drone batteries). With the drone turned on, go to Control then scroll down to Phone Charging and turn the switch on. The trick is, you have to turn this setting on each time - for some reason it defaults back to "off" every time you turn your drone off/on again. I'm using an iPhone 8 - I'm not sure if this works for non-apple products,
