Description
Hello,
I noticed today when I disconnected my development laptop from power, game updates in my, very simple, Tetris clone slow down noticeably.
To confirm the issue is not with my game code, I tested this on the piston getting started tutorial code and see the same slowdown occurs there. Attached a GIF of what I am seeing. You can clearly see the slowdown when the laptop is disconnected from power, and then speeds up when reconnected shortly after.
This seems like it shouldn't be normal behavior, right?

Research direction
Start by reproducing the slowdown with the Piston getting started tutorial, comparing behavior while the laptop is connected to power and on battery. Trace the update loop and timing behavior involved; done means the tutorial and similar games no longer visibly slow down when disconnected from power.
