I created this issue JanDeDobbeleer/oh-my-posh#141
As you can see in the screenshot, the Current value is higher than the Full value.
I had this on windows10. Is it a bug from windows or a wrong calculation in the library?

Thanks

As can be seen in the screenshot, the Full value is lower than Design capacity. Which is normal after some time, as batteries deteriorate. But the controller has no way of knowing exactly how much of the battery is still "healthy", so the Full value is always estimation. Therefore it is possible to charge the battery over the Full value.
It would be best to cross-check this with other source, e.g. the Windows battery indicator (though I'm not sure it exposes enough data) or, even better, BIOS/EFI.
At the moment, I am inclined to say that this is controller inconsistency, and not a bug in the library.
