Magic Battery is a lightweight menu bar tool that displays all Bluetooth-connected peripherals (mice, keyboards, touchpads, headphones, etc.) and the Mac’s internal battery’s charge level in real-time. It not only shows percentages but also intelligently predicts when each device will be depleted or charged, providing a clear overview of all devices’ charge levels.
Features:
**1. Smart Energy Consumption Prediction, Beyond Percentages**
– Continuously tracks each device’s consumption rate, learning its consumption patterns
– Predicts exact depletion times—telling you “depleted on Thursday” or “depleted at 6 PM,” rather than cold “43%”
– Devices that haven’t been connected for a long time are accurately noted, rather than randomly guessing
**2. Charging Time Estimation**
– Displays a lightning icon and estimates the time until full charge when the device is plugged in
– Automatically shows “Charged” after full charge, rather than remaining in “charging” indefinitely
**3. Quick Charge Status Assessment**
– The top row of the summary window directly gives the conclusion: “No need to charge” or “Magic Trackpad is at 12% and needs charging”
– The conclusion comes first, followed by detailed lists, allowing you to grasp the overall situation in a second
**4. Broad Device Support**
*Input Devices:*
– Apple Magic Mouse, Magic Mouse 2
– Apple Magic Trackpad 2, Apple Wireless Trackpad
– Apple Wireless Keyboard

*Headphones and Earbuds:*

– Beats series (Solo 3, Studio 3, Beats X, etc., showing battery levels for both ears)

*Bluetooth Low Energy (BLE) Devices:*
– Automatically identifies all devices that publish battery levels via Bluetooth LE service
– Displays firmware version and serial number
*Mac Internal Battery:*
– Displays current charge level, health, cycle count, battery status, and remaining usage time
– Clearly states the reason for not charging when plugged in but not charged—whether it’s due to optimized charging, charging restrictions, or temperature protection
**5. Highly Customizable Menu Bar**
– Each device can be displayed individually or combined into a single menu bar item
– Multiple display styles: compact progress bars, vertical bars, pure text, text + icons
– Supports colored/non-colored displays, customizable item spacing
– Allows choosing different menu bar views for each device
**6. Device Personalization Management**
– Hide devices that don’t need to be displayed in the menu bar
– Customize device names or display device types instead of names
– The main window supports search, allowing quick device location
**7. Low Battery Alerts**
– Customize low battery thresholds (10%–30%)
– Send notifications when device battery levels fall below the threshold
– The Mac internal battery is also monitored
**8. Minimalist and Unobtrusive**
– Supports pure menu bar operation (no Dock icon), or ordinary window mode
– Can be set to automatically start on boot
– Follows system light/dark appearance automatically
– The main window remembers the last closed size and position
**9. Privacy-Focused**
– All learning data and device information are stored locally
– No need to register, no data upload, no user tracking
– The developer promises not to collect any data
**10. Headphone Support Assistant**
– Battery levels for headphones are read through the free Batteries helper
– The application can automatically download, start, and stop this assistant without manual configuration
Version 10.0.3 Update Highlights:
– Significantly reduced CPU usage and power consumption, preventing the software from becoming sluggish over time
– Fixed issues causing the software to crash during operation
– Allows switching the headphones module on the settings page upon first opening
