Thanks for providing the conversation log, it is much more helpful than the bug report.
Can you try the following after fully charging the phone (that is, after /sys/class/power_supply/sgm41511_charger/status reports Full)?
echo 1000 > /sys/class/power_supply/sc27xx-fgu/calibrate
echo 1000 > /sys/class/power_supply/sc27xx-fgu/capacity
reboot
(The suggestion to write “1” to the “calibrate” property was wrong, it set the capacity to 0.1%)
