I have a couple of weeks ago the new IOS10.1.1 for my iphone 6 installed and since then I have the following problem with my Phantom 4.
If I start with a 100% charged iPhone I could fly more than two pH 4 batteries for this IOS10, now appears while using the 1st battery after about 15 minutes flying. Battery cases low. I stop direct, this morning saw 1% battery so connect the phone to the charger and suddenly I saw 60%. Several times happened but what would happen if I fly by staying? Does anyone know this problem?
