Oh, I should mention that I faced the same issue when running Ubuntu 18.04 (DE: XFCE) last year. Sadly, I don't recall which version of the kernel I was running - the damage to my battery ended up getting so bad that by the end of the year, my battery lost it's capacity to hold charge and I had to replace it (got warnings from OEM software on Windows, as well as on boot - before the bootloader menu loaded).
