I have set the charging limit to 80% using care center, but I want to know if the laptop bypass battery charging after it is fully charged and run on AC power directly or is it bad to keep it plugged in all the time. Should i rather charge it by the 80/40 rule instead of keeping it plugged in when I'm using it?

    Yes, you can leave your adapter or USB-C charger plugged in 24/7 without causing any detrimental effects on the battery wear, The SMART logic in Li-Ion batteries will divert the adapter/charger power to the motherboard when it is 100% charged.
    Don't use battery charge limiter bloatware, the battery "longevity" concept limiting charging to 80% is a myth based on the old NiCad batteries that supposedly suffered from a "memory effect" debunked by scientists and is now even touted on the web to "work" for Li-Ion batteries. https://batteryguy.com/kb/knowledge-base/the-nickel-cadmium-memory-effect-fact-or-fiction/
    ACC no longer has this battery limiting option or it has been disabled by Acer in the latest versions. It does absolutely nothing to slow down battery wear; a new battery can last 4-5 years whatever you do. Also trying to limit the charging is affecting BIOS and MS ACPI drivers in Windows11 possibly interfering with the new S0 Modern Standby protocol that may cause power problems. IMO you can uninstall ACC as you don't need the program, it uses resources running permanently on the background, the driver updater causes issues with Windows11 WAU and ACC hangs a lot. You should do one complete charge cycle with a new battery for BIOS and Windows to register the battery capacity and never let any battery deplete to zero charge (impossible if Windows Power Plan is set correctly with factory defaults) as cells will die and the battery won't be able to charge anymore.
