Which Macs are supported?

macOS 14 Sonoma or later. Apple Silicon and Intel MacBooks.

How much does Battery Sensei cost?

One-time $4.49 for a lifetime license. Lifetime unlock: up to 3 Macs you own. No subscription. Start free for 5 days. No card, no account. When the trial ends, Sensei asks once at launch. Skip the purchase and the free essentials keep working: charge limit, Travel Mode, smart alerts, 24-hour history, per-app drain, live menu-bar watts. Pro adds Meeting Guard, unlimited history, and custom warning rules. Checkout shows your local currency.

How does the license key work?

After checkout, your key arrives by email. Open Sensei → Settings → Pro and paste it in. It activates through Polar and stores the license locally. No account. No login. Lifetime unlock: up to 3 Macs you own. Yearly Patron: up to 5 Macs while subscribed.

Yes. 14 days, no questions asked. Email us and the refund goes back to the original card. Polar handles the payment.

How does the charge limit work?

Sensei stops the charge at the level you pick. Default is 80%: cooler battery, longer life. Travel Mode is one click. Sensei tops up to 100% at full speed, with no macOS slowdown on the last 20%. Your normal limit returns the next morning at 9 AM.

Does Sensei send my data anywhere?

No. Nothing leaves your Mac. No telemetry. No analytics. No cloud account. Your battery history stays on this machine.

How is Battery Sensei different from the macOS battery menu?

macOS shows a percentage. Sensei watches what that percentage means. Smart low-battery alerts at thresholds you choose. A charge limit with Travel Mode. Live charging watts. Cycle and capacity over time. Plus a calm, plain-English history of how your battery is aging.

How much battery does Sensei itself use?

Less than 1%. Native AppKit and SwiftUI. No background polling. Sensei samples only when macOS reports a change.

Is Battery Sensei an AlDente alternative?

Yes. If you want charge limits plus smart warnings and battery history, Sensei is an AlDente alternative. Ships as one notarized .pkg installer. Pro adds Meeting Guard, unlimited history, and custom warning rules. With Lifetime, one payment unlocks Pro for good. Side-by-side comparison lives in the Compare section above.

How do I update Battery Sensei?

Sensei checks for updates on launch. A new build shows up as a quiet notice. You install when you say so. No silent pushes, no nag screens.

How does Meeting Guard work?

Opt-in Pro feature. Sensei reads your calendar locally and predicts which meetings your battery might not survive. When a meeting is at risk, you get up to four nudges: 30, 15, 5, and 1 minute before start. Each nudge names the exact minute the laptop is predicted to die ("dies 17 min into standup") and the plug-in time that fixes it ("22 min on the charger and it lasts through the meeting"). Event titles never leave your Mac. Sensei reads the calendar locally via EventKit. If the risk passes, pending reminders cancel silently.
