My laptop can last a solid 8 hours or more web browsing with windows.
when I put linux (ubuntu for the record) on it, it got a whopping 30 minutes before it needed charging. and it royally fucked my battery health to the point it wouldnt work without being plugged in to the power supply constantly (edit. after a week of use, to be clear, not instantly). Thankfully Dell replaced my laptop for unrelated warranty issue and I got a new one with a fresh new unfucked battery.
