Not sure if it’s related, but since the recent update, I’ve had two instances where I would get out of bed, with a Body Battery in the low to mid 90’s, and, after 30 minutes (or so) it has jumped to 100 one time and 99 the other time. I’ve had a couple of instances, in the past, where it’s done just the opposite, instantaneously fallen 40-50 points, but I attributed that to information getting lost when performing a soft reset (power off/on).
