Personally I don't want the app to layout a check list on any of my quads. Prior to flight there are many other items I check that have nothing to do with the aircraft itself. I had a guy ask me about flying in a specific area he frequently operates his drones at and asked if it seemed like a good spot. I said yes, except it was in classified airspace and he'd have to obtain clearance...he didn't have a clue. How many people think the DJI geofencing feature is the same as a sectional? Even the OP's question about discharging could be answered by reading the instructions. But I don't blame people for asking questions here. I was a bit overwhelmed with the manual of my first quad and I feel this site and videos I watched help quite a bit. Now I'd agree a basic check list could be offered in the instructions. Most of the basics are in the manual but the info is spread out all over place.
I have several laminated check lists for different situations such as times where I want certain sensors on or off for a specific purpose. I consider it more of a cheat sheet when dealing with a function I rarely use.
