BatteryPeek: Clear, Real‑Time Mac Battery Insights from the Menu Bar
Like many Mac users with aging batteries, I kept toggling through multiple tools to answer simple questions: How healthy is my battery? Is it charging efficiently? What’s my current wattage? I wanted those answers instantly—without opening a window or digging into system menus. That’s how BatteryPeek came to life.
The Problem
Battery health details are scattered. Cycle count, maximum capacity, and charging rate matter—but they’re not surfaced clearly while you’re working. When you plug in a charger, you shouldn’t have to guess whether it’s under‑powering your Mac or contributing to slow charging.
The Solution: A Focused Menubar Utility
BatteryPeek is a lightweight menubar app that puts essential battery diagnostics where you need them: always visible, never in your way. It shows live status (charging/discharging), cycle count, maximum capacity %, and real‑time wattage, all at a glance.
How It Works
BatteryPeek uses macOS system power APIs to read battery telemetry directly and updates the menubar UI in real time.
- Live Status: Instantly reflects charging/discharging and estimated time impacts.
- Health Metrics: Surfaces cycle count and maximum capacity to track battery aging.
- Power Draw: Displays real‑time wattage so you can verify if a charger or cable is delivering expected power.
No preferences maze, no clutter—just the numbers that matter.
The Outcome
BatteryPeek has already helped me validate chargers, spot underperforming cables, and understand how my battery is aging over time. It’s become a small, reliable tool that improves day‑to‑day clarity—especially for laptops with hundreds of cycles behind them.
If you want quick, trustworthy battery insights while you work, BatteryPeek sits quietly in your menubar and tells you exactly what you need to know.
