# What do the moon, crossed-out bolt and sparkles icons next to Storage Studio's performance label mean?

They show at a glance how Storage Studio is running:

- **Sparkles** — normal operation, with full effects (Extreme, Rich or Good).
- **Crossed-out lightning bolt** — running light: effects and live graphs are off, either because of the level (Light or Minimum) or because Low Power Mode is on.
- **Moon** — Survival: background work is paused because your Mac is under heavy load.

Hover over the label to see the reason in words. See [what each mode means](https://storagestudio.us/faq/performance-battery/what-are-storage-studio-performance-modes).
