Hi,

apm seems to be reporting percent of last charge, not % of design-full-charge.
That may be part of
the problem.
one problem I often have had with "genuine parts" (= most usually some
cheap china stuff) is that while the elements may be decent for the
first 12 Months or so, is that the controller is not as smart or does
not report full information or is anyway lying.
Of course this is general speaking, there are many of manufacturers and
this might change from laptop to laptop replacement.
6Months and a dozen of cycles would still qualify the battery as
reasonably new, except for a warranty case!
For example, it may not distinguish between a design charge or last charge.
It is correct to report the last charge as capacity.
E.g you have a 50Wh design capacity, but your cells now have about 40Wh
effective, if you did not make a full charge you might have 25Wh.
If my laptop is consuming 25W, it will last 1h, not more, because that's
the juice you have in.
This still does not explain your sudden percentage drop.
Is your laptop new enough to run acpi?
I will try to work on OpenBSD support for batmon.app during this holiday
season.
