Mouthful of very bad words!!
The juice pack broke. The little outlet hole in it, has something lose after it fell and dangled from the desk.
It didn’t hit any surface whatsoever but hung with the phone’s weight, and that was obviously enough.
Tomorrow’s train ride is a loooong one, and it means being very careful with using the phone including the camera, as I need to be 100% sure I have battery enough once down in Nagasaki (so I can find my hotel etc.).
Wish me luck!!
