Retina, 12-inch, 2017 best OS recommendations for the best battery performance

Hi,

I have recently purchased a used MacBook Retina 12 inch for peanuts. I have decided to upgrade directly to Sequia without actually testing the performance of the battery on Monterey. I am tempted to rollback to Monterey to get more out of the battery but before I do so, I was wondering if anyone had similar experience with the Retina 12 inch 2017 model? I can't really tell how long the battery will last but if I had to guess, it's about 2-3 hours. The amount of cycles is 169.

Thanks.
