Battery with unexplained usage

I’ve submitted a support request about this but I’d like to crowdsource some information too.

I’ve got a FW16 with Ryzen 9 7940HS, running Win11 23H2 build 22631.4112, and openSUSE Tumbleweed on a secondary 2230 SSD.

I’ve noticed recently that the battery life isn’t what i want it to be, and openSUSE was reporting about 70% battery health. I’ve only had this computer for less than 3 months so this is a real shock to me.

On Win11 I generated a battery report (powercfg /batteryreport) to figure out what was happening.


This is the most concerning entry.

Is there any good reason why, for a laptop that I only got in June, there’s an unaccounted 3 months of really intensive battery usage, before the laptop even shipped to me? Is this a second-hand battery? What the hell is happening?

If anyone has suggestions I’m all ears.

For context, my own personal battery usage starts here halfway through the red arrow (it was delivered June 17th).

So what is everything else?

I would question the accuracy of the battery report, as this is mine :
DESIGN CAPACITY 85,001 mWh
FULL CHARGE CAPACITY 88,592 mWh
CYCLE COUNT 95

But I do baby my battery a bit and limit the charge to 85% of max battery.
