I'm a bit confused... the german update says something a little bit different... Or not? ...use google translate for the first paragraph:
There have been recent incidents that some Cypres 2 devices off devices not after 14 hours. In this case, they show zero, but do not work and do not respond well to a button click. Moreover, there was a case of activation of a packing sheet, which is not allocated to this phenomenon. Intensive investigations indicate that this (cause much static) with low humidity and the packing to do on non-conductive surfaces has. Container as well as caps are made of nylon and create friction during movement and may enormously high voltages. A floor covering of synthetic fiber favors the additional very strong. The number of incidents that can lead to this behavior, however, is very, very low.
