Battery with unexplained usage

Framework Laptop 16
1

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.

Do you have a battery charge limit in place? Sometimes when a low battery charge limit is placed it confuses the coulomb counter sensor in the battery that detects the charge level.

You can try discharging the battery completely to 0% or some very low percentage around 10% or lower, then fully charging it and checking the entries again.

If this does not work, I recommend reaching out to support to get them to check your device as it is still within the warranty period.

I can confirm that putting a limit on the battery charge does effect the “capacity” and “life” of a battery. :battery: Almost all battery reporting tools do not have a mechanism to realize that a hard upper charge limit is imposed.

I surprised myself one day thinking I would just check and see what my battery life was…sure enough it had lost exactly 30% of its life in a few months. :scream: Exactly the same as the 70% charge limit I had imposed on the system after I first got it. Took me a minute to realize that it was reporting exactly what it saw… :grin:

I have actually tried this, thank you for the suggestion! Doing a full charge cycle seems to have done nothing. I’ve contacted support and not heard anything just yet.

Also I’m afraid this wouldn’t add up for me, I do have a charge limit of 95% set but that wouldn’t account for thinking the battery is at 69% health.

Equally it doesn’t account for three months of intensive use on the battery report before I even got the thing.
