I feel like if this was more normal, alot more people would be complaining and there would be recalls. I just reset under my own say so. It's only been a few days so I'll let you know if the issue returns.
Hi, I'd like to add that I recently got the Surface Book 2 a few weeks ago (heavily discounted off of their website) and I love the machine. The battery drain is terrible while off. I had to leave for 3 days and I left it in my room from 100% battery down to 80% battery in just 3 days of it being off. It was funny because when I first got it, both batteries were completely drained.
It's been a few more weeks since your last post. Have you noticed if it helped or not? Thanks :)
Battery drain issues are still gone. A reset may not work for everyone but it worked for me thankfully.
