This happened at a very inopportune time so apologies for the text being a bit bad. background: framework laptop 13 with 7640 u running fedora 40. ran great for a few months. issue: played some games on battery power. battery health went from mid 90’s to 43. i know playing on battery is bad for it but that is more what i’d expect if I took a hammer to it. what i’ve tried: rebooted, cleared upower history, removed 90% charge limit in bios then shut down and charged.

Any thoughts would be appreciated.

Edit: I ran it out of battery while on the bios screen then charged it to full before powering it on. Battery health is now showing 91%. I’ll see if it lasts, but I’m glad I didn’t just go out and buy a battery without troubleshooting first.

    A couple things to check using a quick bash script:

    #!/usr/bin/env bash

cd /sys/class/power_supply/BAT*/
echo "Charge cycles: $(cat cycle_count)"
printf '%s\0' 'Health: ' &
bc <<< "scale=3; ($(cat charge_full) / $(cat charge_full_design)) * 100"

    That should print out the wear cycles the battery has endured and its reported capacity over design capacity. If your battery has less than 1000 cycles and the health reported from the battery is less than 80%, it might be best to contact Framework for warranty replacement as the battery is likely defective.
