Here a solution if you want to fly more buy more battery packs and recharge them to 100%. I hate to say it but let's say your phone battery was 5% and you had an emergency and the phone decided to die.dont bash dji for user stupidity. When I had a bad firmware update that caused my phantom Drone...
I find the mavic pro a awesome Drone buy longer flight time and maybe better range for longer distances be nice. Also a wider camera lens like the phantom 4.
