Laptop battery health question

If I plug in my laptop and it charges to a set level (it has let me set 80% as a cap to protect battery health), does the power draw then bypass the battery and just come from the USB-C charger, or does it come through the battery, wasting cycles?

 

Would this be different if I changed the set level to 100% or to 60% (which is what ASUS recommends if leaving the machine plugged in for a long period of time)?

 

I hope someone can answer this, as I intend to use this laptop for the next 4 years, so want to get the most I can out of the battery.

I’m not 100% sure it applies to you, but I can say that my MacBook has only accumulated 10 cycles on the battery in the last year even though I use it daily, it just stays plugged in

Interesting stuff, thank you for the reply! I have 5 cycles on the battery and have been using this for 5 days, mostly unplugged. Is that cause for concern or ok? The full capacity is still the same as when it was manufactured.

 

I would assume that the power is directed straight to the components that need it when plugged in and fully charged, or at least I would hope so?

I’d sure hope so too. Don’t sweat it too much though, These batteries don’t just magically stop working. I see no reason why, in completely normal use, a battery wouldn’t last 4 years.

Thanks mate that helps a lot, I'm just a little paranoid as I had an old HP that I obviously didn't brilliant care of the battery in, so I didn't want to repeat that on my new laptop as it cost me a lot more, and I'll need to be saving for the next few years.
