А bit more battery life I think is thanks to lower capacity of air that props push out. May be that make sence in hover mode, but in other I'll prefer (perhaps) the normal props.
Only the LTE version has GPS. I have Apple iPad 6 Wi-Fi + Cellular /9.7"/ 128GB (2018). I hotspot my Android phone's LTE to iPad, because of the map that IOS can't save offline.
