OMG, I ended up buying a 5th gen Ipad w an A9 processor and 128gb, and just today flew three batteries flawlessly-using Litchi. I am done with DJI Go 4, the updates are stupid and never ending. It has been over a year since I have had a 'flawless" flight experience over three batteries, until today. I'm sure the new Ipad helped, but when I started DJI Go 4 it wanted me to do yet another update-I used Litchi, and was not harassed into screwing up my day...I will not use DJI again for any actual flying, they are over doing the tweaks and causing too many problems for too many flyers. I'm so relieved, too many times in the past year while flying my P3S and for the last half a year Mavic Pro (I have two), I could fly 'blind', meaning the feed would disappear but I still had control through the remote. Videos would stop, my batteries on my iphone and android would get hot and barely last three flight batteries, the app would crash, today for over an hour in the air my controller only used 25% battery, my Ipad was cool and had 85% left and all videos were flawless, not jittery...in other words, i had fun again and want to fly again. No more DJI Go for me, thanks.
