I cannot understand how the XPS 15 achieves so much better battery life compared to, for example, the MSI GS65 Stealth. Sure, the battery is 15Wh bigger (97Wh vs 82Wh) but all the other components except for the GPU (1650 vs 1660Ti) are identical. Nvidia Optimus should be disabling the GPU for all non-gaming activities.
I read many reviews where the XPS shows almost double the Chrome browsing battery life compared to gaming laptops such as the GS65.
Trying to understand why.

Often times you can have two laptops from different brands have the same specs on both, the difference would be how they design the PCB of the laptop's boards and then the design of the BIOS to allow all the components to communicate with each other, which will also be further aided by the drivers/software installed for the platform.
