How's everyone's [55Wh] battery health and wear looking?

I’m not really happy about this to be honest, as the claims by Framework that the battery is designed to retain 80% capacity after 1000 cycles seems to be a bit misleading. I’m not anywhere close to halfway there!

I think the battery is capable of retaining 80% after 1000 cycles as long as you don’t 100% for a year or but your computer in a hot place. However the battery management might do some shenanigans to negatively affect the capacity

Here’s my rendering of the battery right now, after slightly less than a year of use:

The red line is the evolution of the battery health. According to the current levels, it’s at 3286000 out of 3572000 design capacity, which is 91.99%. You can clearly see “drops” in that line where the battery was somewhat “damaged” in one shot, which is, I think, the most interesting part of that graph.

I found the answer, the “drop” is likely due to the BMS deliberately lower the limited charging voltage after some time or cycle to use only a part of your battery’s capacity, this makes the user think the battery has degraded. The motivation of this is yet to known. If you have the opportunity could you please fully charge your laptop and read the voltage(while still plugged in)? If that voltage is significantly lower than 17.6V(such as 17.4V), then this is the exact problem. My 61Wh battery decided to “degrade” 9% by limiting the voltage from the original 17.8V to 17.6V. The same 0.2V drop is witnessed here(55Wh, 17.6~17.4V).

Purchased January 2022, battery level kept between 75 and 80%, used daily, mostly plugged in at a desk. Swapped mainboards from the 11th gen i7 to an AMD board, so I expect that the cycle count is at least 1.5x-2x this.

Not bad I don’t think following a full drain and charge to 100%.

Note that the full voltage of the battery is no longer 17.6V but only 17.4V. If the original voltage is restored, your actual capacity is likely going to be 52~53Wh.
