Question Any programs I can use stress test Battery Run time?


Jul 16, 2018
HI, can anyone recommend me programs that I can run on a Windows 11 laptop to see how long it can run on battery for light, moderate, and heavy load? I have an HP Spectre x360 and a Lenovo Yoga 9i and I am trying to decide which one to keep.
The battery life on both is nothing to like. My last laptop is a THinkpad Yoga 370 that came out in 2017 and it's hard to believe that 5 years later, battery life still bad.
Yes both of my laptops I am trying to decide have OLED screen at 3000x2000 and 4k respectively but I would have thought, they managed to do this because battery life would be respectable.
Anyways to not digress any further, I'd love a way to test both laptops and see which one lasts longer so I can return the other one.

Not a specific program, but I generally use youtube playback as a test. Just find a very long video on youtube with lots of motion and play it. for a higher stress situation, I afk in a game.
