FAQ

Common questions about Blattery

Is this safe for my battery?

Yes! Setting charge limits to 80% is actually recommended by Apple. It reduces battery wear and extends lifespan. Blattery uses Apple's IOKit API, which is the same method Apple uses for battery management.

How does sailing mode work?

Sailing mode maintains battery in a custom range (e.g., 60-80%). When battery drops below the lower limit, charging starts. When it reaches the upper limit, charging stops. This is the most battery-friendly way to manage charging.

Do I need admin privileges?

Yes, to change charge limits or enable/disable charging, Blattery requires admin privileges. This is because we're writing to the SMC (System Management Controller), which is a protected system resource.

Will this void my warranty?

No. Blattery uses Apple's public IOKit API to manage battery charging. This is the same API used by macOS itself. Your Apple warranty remains valid.

What's the difference between CLI and Pro?

The CLI is free and terminal-based. The Pro app (€8) has a beautiful menu bar UI, real-time status, temperature monitoring, smart notifications, and a health dashboard. Both have the same core features (charge limits, sailing mode, scheduling).

Is this available for Windows or Linux?

Currently, Blattery is macOS-only. However, we're working on Linux support (coming soon). Windows support is not planned due to WMI limitations.
