Quick question: how old is the battery? I've seen it alleged that
lithium batteries lose up to 20% of capacity a year, regardless of
charge cycles, and I certainly had a laptop battery which stopped
charging after about five years of reducing capacity. I also have a
netbook, of the same brand, which is more than seven years old and
still holds about half the charge it did when it was new.
Many people replace laptops in much less than five years, though
probably not people who run Linux on them.
