during a beautiful sunset cruise last nite, i had an issue at the end of the flight with my android phone. I had flown for 10 mins or so, taken some video and stills of a beautiful sunset. temps were in the low 20's, not to mention my fingers were getting cold! just as i ended my flight, and did a hand landing (2nd one!), my cell phone shut down, as if the battery had died. the flight went flawlessly, i basically went straight up to get video of the sunset, and came back down. my though is that the phone got cold and being almost 2 years old, it's battery may not be as good as it once was, and the phone didn't take to the cold very well and after 10 mins or so it shut down. could be a problem if i had ventured further away with the phantom, and lost my "eyes". it sounds like i am going to need to get out of phantom mode sooner instead of later, so i have homelock and courselock available, although i guess switching off the tx would instill a return to home. has anybody else had their phone die while in flight? would you say the android app is battery intensive?
