Both batteries in use?

[BadPenguin]

Hello,

I have a Surface Book with Performance Base (512GB) and I wanted to ask, if it is normal, that both batteries are in use when I use it in "notebook mode". This seems a little bit silly to me, because if I'm using the Surface Book in "notebook mode" and both batteries are in use, the energy of the battery in the clipboard is wasted when I want to use it in clipboard mode. I hope you know what I'm trying to say.

Thank you all in advance!

That is how it is designed to function...

Which way do you mean? That both batteries are discharging at the same time or that the base battery is used first?

Because I read on reddit, that the base battery should be used first until it reaches ~40% and only then the battery in the clipboard is touched.

My SB uses both batteries at the same time.

I like the method of the old Asus Transformers in that when you took the tablet off the keyboard it was at 100% if possible and that when you put the tablet back on the keyboard the keyboard charged/transferred it's charge to the tablet. Could Microsoft do that for us in a software update at some point?

Yes, but charging the battery from another battery is very inefficient.

No problem I was just telling you what it did and it sure seemed to work very nicely back then.
