Your parts, your order.

The icon, the percentage beside it or inside it, and the time left, in the order you choose. Red when low, yellow in Low Power Mode, or monochrome.

Alerts at your levels.

A notification as the battery drains to the level you choose, and as it charges to 80, 90 or 100%.

Everything in one menu.

A 12-hour charge chart, live watts, cycle count, capacity and temperature. The time left learns how you use your Mac.

Get started.

  1. Download CommonBattery.zip, unzip it, and move Common Battery to Applications.
  2. Open it The first time, macOS says it can't verify the developer: the build is signed but not notarized. Open System Settings › Privacy & Security, scroll down, and click Open Anyway next to Common Battery.
  3. Set it up Pick what the menu bar shows in Settings, where a shortcut also hides the system’s own battery icon.

Or, from a terminal, with no Open Anyway step: curl -fsSL https://oddurs.github.io/common-tools/install.sh | sh -s -- battery. Every step, with checksums, is in the install guide.
