macOS Sonoma 14.8 or later, Apple silicon. A licence is required. Buy one, $15

BatFi’s menu beside its Charging settings: the battery at 75 percent with power distribution and the apps using the most energy, and a charge limit held at 80 percent while the Home automation overrides it to 75.

Rules that follow you. Hold 60% at your desk, top up before you leave, charge fully at the weekend.

BatFi’s Automation settings: charging automation switched on, with a rule named Home holding 75 percent at any time within 300 metres, marked ACTIVE.

And everything macOS keeps buried. The readings, the switches and the shortcuts it never puts in front of you.

  • BatFi’s charging settings: automatic charge management on, an automation holding the limit at 75 percent, the limit slider set to 80 percent, and an option to discharge when charged over it.

    Stop at 80%, or charge to full.

    A limit for every day, and a full charge before a flight.

  • What is drawing your power.

    Watts in, watts out, and the apps burning it right now.

    BatFi’s menu showing power distribution, 11.2 watts in and 11.2 watts out, and the apps with high energy usage: iTerm2, Safari and WindowServer.

  • Cycles, temperature, health.

    The readings macOS buries, put in your menu bar.

    BatFi’s menu settings: show power source, battery cycles count, battery temperature, battery health, last discharge date and last full charge date.

  • A menu bar icon you can live with.

    Percentage, time left, monochrome or not.

    BatFi’s status icon settings: the style set to Dynamic, with options for a monochrome icon, the battery percentage and the time left.

  • Told once, when it changes.

    Charging state, calibration, and the rule that took over.

    BatFi’s notification settings: charging status changes, optimised charging alerts and calibration reminders, with a low battery threshold slider.

  • Power modes from the keyboard.

    Low, high or automatic, on a global shortcut.

    BatFi’s hotkeys: toggle charge to 100 percent, run on battery, inhibit charging, and low power mode recorded as control shift command L.

$15, once.

Not a subscription. One licence covers every Mac you own.
