This is demonstrably false — I have two 2018 Thinkpad T480 laptops, one running Windows and the other Linux. The windows one gets around 11 hours of moderate use per charge, and the Linux one about 10. And I bought these used with batteries that had quite a few cycles on them already. Laptops with long battery life are out there; Apple machines are not the only option!
