Is it just me or does Linux use way less battery

I just installed Mint today and oh my god my laptop isn't fucking going full airplane mode from watching Youtube with Discord open. Talk about having a full on Dell Optiplex 15 9530 and yet after 3 years my laptop could barely last 2 hours without charging.

Now I'm on Linux Mint. Fans are quiet. I currently have 12 tabs on Brave with Discord, Wireguard, Steam, and Claude open. It has been an HOUR maybe and my shit is at 74%. I'm in shock, it literally fixed almost all the problems I had with this laptop

Tbf if I did a fresh Windows install it probably would've ran fine too. Prob just had too much clutter. But my lord does Mint run smooth. Can't wait to get another SSD for my laptop so I can dual boot Windows 11 and Linux Mint.
