@surfboomerang I do not know for the S9PP but my son’s S5P has this bug as well, at 96% starts to beep and connect/disconnect from charging, if you unplug it the watch will automatically say that is 100% charged, so I think is a software bug. BTW I’m pretty surprised how well performs the S5P, despite its differences with the S9B, I’m also surprised with the readability of the screen.
