When I fly my mini, I always top off all the batteries when I'm done. I have an iPhone, so I don’t have the issue of my phone being charged by the remote. Normally, I still have all 4 lights lit on the remote when I’m done, rarely 3. Should I occasionally discharge my remote battery down to say one light before charging? Didn’t know if I am creating a short memory by charging the way I currently do. I guess the same question goes for a mini battery if I’m charging it at 60 or 70%, instead of running it down to 20 or 30%
