Same behavior here. When happened, several times, battery levels range from ~30% to ~45%.
What I've noticed also is that while charging after these sudden power offs, if you turn on to the battery charge animation, wait the screen to turn off, turn on again ... the battery level displayed goes down 1% every turn on until it does it no more. This could be done 10 to 15 times, each time an one percent less than before.
