For what it is worth, you may have more than 77 cycles on your battery. There is a bug in the firmware[1] which results in the cycle counter wrapping around every 256 cycles.
Note that despite it claiming it applies to the 7040-series, it applies to all extant Framework devices with batteries. ↩︎
You are not alone with this issue.
I only use my FW16 a few times a year, and I noticed my battery health dropped from 99% to 73%a few months ago after I removed the charge limit from 60%. It also coincided with the battery discharging to 0% because of sleep, so I am not sure which of these two events is the culprit. It is extremely disappointing as my battery has only 59 charge cycles.

In my case I have a wf16 gen1. it have +18 month and it most of the time plug on power… I config the battery charge limit @60%…
Yesterday I get that

Then I change the charge limit for 100% charging, have a full discharge + a full charge (and wait >2h for full charge)
That way the qualibration is donne, and the cell re-balanced. After that I get:

So you can get a full battery cycle and after re-callibration / cell re-balanced you may get better capacity.
After that, may advise.
