    Hi All,

    Was just checking the battery health of my SB2, and noticed that - according to the report - the overall battery capacity dropped something like 5% in a week ("battery 1" dropped by 8% or so and hasn't recovered in the two months since). After a year, overall capacity for the two batteries combined is at 90% of original, but I just wanted to see whether anyone else has seen this happen. I've owned lots of laptops (and also have a Surface Pro 4), and have only seen steady falls rather than dramatic ones like this...
