How do I change the battery level at which Storage Studio pauses?
Short answer: Choose Smart in Settings → Quiet Hours and set Pause when battery drops below (30% by default). It only applies on battery power — when plugged in the percentage is ignored.
In Settings → Quiet Hours, choose Smart, then set Pause when battery drops below to the percentage you want (30% by default). Below that level, on battery, automatic work waits.
When your Mac is plugged in, the percentage is ignored. If you want automatic work to avoid battery power more firmly, raise the number. For more about energy use, see performance & battery.
