Battery charge limit occasionally ignored

What I am now observing since my last post is that the charge limit is now completely ignored for my Laptop 13. I have to go into the bios, change it to something other than 80, save and exit, restart back into bios to put it back to 80. Then it will work again for a little while until it stops, and this procedure is needed.

To confirm i have turned off battery life extender already a while back. I wonder if i should try that procedure with that option as well.

I think a simple reboot of the EC will suffice instead of going into BIOS and setting values back again.
EC reboot procedure:

  1. Power off the laptop (not suspend)
  2. Remove the PSU cable.
  3. Leave the laptop powered off for 2 minutes. (The EC powers off about 40 seconds after the CPU has shut down and the PSU cable removed, but that exact time is sometimes difficult to judge, so I say 2 minutes.)
  4. Plug PSU back in and power on the laptop.

The EC should have rebooted.
you can use “sudo ectool console” to see if the timestamps have started back at 0.

The power off and unplug PSU is important, because in many situations the EC stays on even with the CPU shutdown or rebooted.

I’ve noticed the same problems with Battery Life Extender and disabled it.
But I’ve also noticed, that is you start at higher percentage and the laptop runs on battery till it reaches the desired value then it toggles between charging and discharging.

On my old Dell XPS 13 it was possible to set the min and max charge value, so it did not charge until min is reached and then charged till max. For example between 60% and 90%. That was ok and my battery lastet at over 90% capactity for 8 years.

Adding to report this issue for the new Framework 13 AMD Ryzen AI 300 model as well. Battery charge limit is not consistently enforced even while Battery Life Extender is turned off.

Also seeing this issue with my FW13 HX370. It worked at first when I set it up, then it stopped. I have the battery life extender disabled as well.

Edit: Ok- I’m new to Framework. I can see there are beta BIOS releases being discussed here on the forums and they are aware and working on the issue! Framework Laptop 13 Ryzen 7040 BIOS 3.08 Release BETA - Held
