Shortly after Christmas, there are likely to be thousands of Phantoms of various persuasions firing up on batteries that have just come out of storage since manufacturing in China. Yes, The Fine Manual clearly states to charge everything first. No, lots of people aren't going to do that. Given the threads about partially charged batteries confusing whatever 'intelligence' is baked into the system, this might be an interesting, albeit unintentional test of the phenomena. The trick will be to distinguish this failure mode from the dozens of other potential Post Christmas Drone Blues issues... I sure would not want to work DJI technical support in the upcoming weeks.
