So yesterday it happened for the first time as I'm doing a range test from a mountain top over looking a plain field, I make a terrible mistake... I fly out to 18k feet and still have full RC and video feed signal. I see the battery meter for rth is getting close. So I decide to turn back home, here's the mistake... Forgot to take into account tail wind on the way out. Now my rth requires more battery than I have left and I'm in controlled panic mode... To make things worse now my phone turns off at 80% battery life. Now I'm in full panic mode. I try to restart it and every time I open the DJI go app it crashes my phone again. After a few tries it works and I have visual feed again (by the way it only turns on while plugged into a charger as if something is tricking it into thinking its out of battery but it's not, not even close). I try a few things in hopes of saving some battery vs flight time, from flying at 50% throttle to Atti mode hoping the extra speed can make up the time gap vs battery life to get home but nothing. Thinking that I might not make it home and still about 4000 feet out and nearing critical battery levels, I decide to search for a safe place to land. I see a nice flat place and screen shot my map so I know where to go find my phantom after. I cancel rth and start descending... Well as I'm about 100 ft from landing my phone crashes again. Now I'm in huge panic mode and really pissed off. Thinking I can't do a blind landing I initiate rth again from the RC, there goes some more battery while it ascends to the 200 ft I have it set to. Again the phone restarts but crashes everytime I open the app. The longest 2 min of my life go by but now I can hear it somewhere in the distance... Finally I spot it as it flies over me and starts descending to its home point, and in huge relief I take back control and bring it down as fast as it will let me. As soon as it lands I power down, and once I'm able to reboot the phone and successfully open the app I check the flight log recording on the app and see its landed with 4% battery. I'm hoping the battery hasn't suffered terminal damage here. I've recharged and checked it volatage and capacity and it all seems ok... So what I've learned on this flight and experience is, #1 fantastic range! #2 never do that again, #3 leave plenty on margin on battery level when flying out with a tail wind. #4 what the heck is causing my phone to crash mid flight!!? Anyone have the same issue of phone/tablet crashing mid flight?
