Features & Usage
What is Charge Limiting?expand_more
Charge limiting prevents your battery from charging beyond a set percentage (e.g., 80%), which helps preserve long-term battery health. Keeping your battery between 20-80% can extend its lifespan by up to 2x.
What is Sailing Mode?expand_more
Sailing Mode allows you to discharge your battery to a specific level while keeping your Mac plugged in. This is useful for battery calibration and maintaining accurate capacity readings.
How does Heat Protection work?expand_more
When your Mac's temperature rises above a safe threshold, Celvio automatically pauses or limits charging to prevent battery damage. This protects your battery cells from thermal stress during heavy workloads.
What is Discharge Mode?expand_more
Discharge Mode actively drains your battery even while plugged in, using battery power instead of adapter power. Useful for reaching a specific charge level quickly or testing battery health.
What's the optimal charge limit?expand_more
For most users, 80% is the sweet spot that balances battery longevity with daily usability. If you rarely unplug, 60-70% is even better. If you need more runtime, 90% still provides significant benefits over 100%.
How often should I calibrate my battery?expand_more
Modern MacBooks with Apple Silicon generally don't need frequent calibration. However, if your battery percentage seems inaccurate, running a calibration cycle once every 2-3 months can help. Use Celvio's Sailing Mode for easy calibration.
Can I customize the menu bar widget?expand_more
Yes! You can choose what information to display in the menu bar, including battery percentage, health status, temperature, or power flow. Right-click the icon to access preferences.
How does Smart Scheduling work?expand_more
Smart Scheduling lets you set different charge limits for different times. For example, charge to 80% normally, but allow 100% overnight before a travel day. Configure schedules in the app preferences.
Will Celvio void my warranty?expand_more
No. Celvio uses official macOS APIs and SMC commands that are the same ones Apple uses internally. It doesn't modify any system files or firmware. It's completely safe to use and won't void your warranty.
