Windows 10: Windows 11 Update Battery Automatically going from 50% to 100% without charging....

Hello, I have updated to Windows 11 like 2 months ago. I did not face any problem but on 22 April My system started to jump from 50% battery to straight 100% , for 1 day I thought it was a glitch but this happens daily now when I boot up my battery is sometimes really low and sometimes 100% and sometimes it jumps to 100% in front of my eyes I don't know what is happening. Please help Microsoft :

:)

 

Battery stops charging at 50%

Apparently there is a setting (on Vaios only?) to limit the battery charging to 50% or 80% to increase useful battery life. I changed it to 80%, now my battery charges to 80%. It is also possible to remove this limit altogether so that the battery charges
to 100%.

 

Acer battery won't charge

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
Here's the report file
