@Jake_Naviasky I replied to you on another thread about this; I see what you mean; I’ll keep an eye on this on Fedora.
Edit: FWIW watch -n 5 cat /sys/class/power_supply/BAT1/status so far, with the battery already at the BIOS charge limit of 80% and AC plugged in, shows no such flapping. It just stays at Charging with the upower-derived full charge estimate seeming to be some recent value that I expect to soon change to “Estimating” based on previous behavior (on this laptop and previous Thinkpads).
@Kieran_Levin if this is actually what is going on - micro charge start/stop cycles - then an additional “charge start threshold” feature in the BIOS might make sense - anything on the roadmap?
Then again, there’s the EC thread - is Framework or any of your distro contacts looking to upstream this, in tlp and/or the kernel’s /sys/class/power_supply/.../start/stop_charge_threshold APIs?
