Battery discharge is quite linear, because the OS is using the information from the BMS chip in the battery pack, which tracks the energy stored in it rather accurately, and also tells you very accurately how much power is drawn or put in. Personally I don't use Windows on any of my laptops, so I only noticed this one day on my work laptop. On my Linux laptops my status bar is literally just doing a weighted average of "time_remaining = energy_remaining / current_power", which works rather nicely. That a supposedly top-notch software company like Microsoft is trying to gaslight their users into "predicting battery life is like hard you know! We're gonna remove it because it's so inaccurate, it's basically unsolvable aha" makes me throw up a little, but is also such an accurate and damning reflection of the way these companies conduct themselves.
