Have you checked whether the work laptop's bad battery life is due to the OS, or due to the mountain of crapware security and monitoring stuff that many corporations put on all their computers?

I currently have a M3 Pro for a work laptop. The performance is fine, but the battery life is not particularly impressive. It often hits low battery after just 2-3 hours without me doing anything particularly CPU-intensive, and sometimes drains the battery from full to flat while sitting closed in a backpack overnight. I'm pretty sure this is due to the corporate crapware, not any issues with Apple's OS, though it's difficult to prove.

I've tended to think lately that all of the OSes are basically fine when set up reasonably well, but can be brought to their knees by a sufficient amount of low-quality corporate crapware.
