Does iOS slow down/throttle the iPhone speeds when you hit 20% battery, even without turning on low power mode? I swear things get slower even on my XS Max once it hits 20% battery, even though I do not turn on low power mode.

Unless you turn on low power mode, nothing should change.

I didn’t think it was supposed to change, but especially in a game it sure appears to slow down. Maybe it’s on my head, but I sure do to think it is;(. It’s when it hits the “red” below:
