I had the opportunity to fly al three batteries consecutively this morning using my S9+.
Only one hiccup, which was a DJIGo4 app disconnect midway through the first. App reporting AC disconnected when in reality it was only the USB link between the RC and APP. Could not re establish this connection without first flying it home landing and restarting the RC. However this was almost certainly caused by me launching DJIGo4 from the Icon after the USB lead was connected. Instead of my long standing methodology of launching in response to the USB connect prompt and pressing "Just this Once" ( I have multiple flight apps). This has never failed me with my S7e and I will stick to using this method for reliabilty with the S9+ from now on.
One of the flights was a 9km route around a farm with Litchi. The rest was with DJIGo4 taking video, stills and panos. All 3 batteries down to 10% and RC battery ended up just over 25% which was a little lower than I had hoped. So some will find this abit tight I guess.
Again the screen was great. Overcast day here so could not really test full brightness vs sunlight. However there was no need fro me even touch brightness controls. On the old S7e I was in the habit of setting manually full bright every flight.
I suppose only criticism I have is that the upper edge of the screen sits in a ittle too tight to the underneath of the RC making it a little fiddly to interact with the menu bar. But is still totally do-able.
