BatteryPeek

BatteryPeek is a lightweight macOS menu bar app that surfaces your MacBook’s real battery health at a glance. Instantly see cycle count, current maximum capacity versus design capacity, and live charging wattage without opening System Settings or terminal tools. BatteryPeek helps you understand wear over time, spot abnormal drain, and verify charger performance.

Designed with a clean SwiftUI interface, it stays out of your way while giving precise readings when you need them. It’s ideal for power users, travelers, and anyone who wants clarity on battery longevity and charging behavior.

Upcoming enhancements include trend logging for capacity over time and fast‑charging warnings, so you can catch unhealthy charging patterns early and keep your battery in good shape.
