Upower report battery capacity of 500wh, if true great, if not I would like to know the actual discharge time.

The decimal point is in the wrong place. The tool reports a design-full capacity of 550Wh. The battery capacities sold by Framework have been 55 and 61Wh. I think we can safely assume you have a 55Wh battery.

That’s interesting… I agreed that the decimal point is in the wrong place, it seems. Can you please check:

cat /sys/class/power_supply/BAT0/charge_full_design
cat /sys/class/power_supply/BAT0/charge_full

Change BAT0 to whatever it is there, say BAT1

Icarus ~ # cat /sys/class/power_supply/BAT1/charge_full
31360000
Icarus ~ # cat /sys/class/power_supply/BAT1/charge_full_design 
35720000

Looks like this is not a problem with upower… is this problem new? Mine one reported one less digit.

cat /sys/class/power_supply/BAT1/charge_full_design
3915000

yes, it occurred shortly before the post, by at most a couple of days. I regularly check my battery, as it show up at the same key binding as the time.

Do you have sys-power/acpi installed? Try

acpi -i

Mine reads:

Battery 0: Not charging, 69%
Battery 0: design capacity 3915 mAh, last full capacity 3565 mAh = 91%

Huh. Can you head /sys/class/power_supply/BAT1/device/*?

I wonder if it’s being bound by a different driver than usual.

On my 11th gen (kernel 7.0.7, firmware 3.22) I’m not seeing this; my device info follows:

==> /sys/class/power_supply/BAT1/device/hid <==
PNP0C0A

==> /sys/class/power_supply/BAT1/device/modalias <==

The issue no longer appear. I’m on a new kernel, and accidentally drained the battery to below 10%.
