Hi All, Have a CoreBook X dual boot Windows and Ubuntu.
Ubuntu latest version or Elementary Os latest version - does not have overall battery information or indicator icons, so we don’t know how much battery left before the laptop dies … 
Likely BIOS related (?)
Can confirm it is a problem with Chuwi in particular. Their ACPI interface does not behave normally.
I made an entry for this on the Arch forum (here)
Thanks for the update, looks like there’s no actual fix.
There is BIOS update that solves battery issue. I saw yt who simoly has newest verion 2.20.1275 when im stuck with 2.20.1271…
