My 2021 M1 Pro 14" is at 83% of the original battery capacity so a new MBP would be the expensive way to get a 17% improvement in battery life. Replacing the battery is the cheaper way.
The M1 is already really efficient. It idles at 2 watts with the brightness at 1 click. I am generally curious how much more efficient the M4 is when both doing nothing and running apps. I try to keep the battery between 20-80% which means I only get 60% of the total battery capacity. Going from 2-10 watts on M1 to possibly 1.6-8 on M4 might actually be noticeable, above what I get back with the new battery. But I would need to buy one and then find out what the actual real world difference is.
Are we at a point where the screen power efficiency improvement has more of an effect on battery life than the processor efficiency? If so, OLED might be a more noticeable change than upgrading to M4.
I hope Apple doesn't downsize the battery drastically in the future because I sometimes use the laptop to charge my other devices like my phone and AirPods.
And now for the joke part of my post: I should probably just quit my job and then I don't need to use my laptop at all and definitely don't need to worry about battery life.
