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 status in real-time. It not only shows percentages but also intelligently predicts when each device will be depleted or charged, giving you a clear overview of all your devices’ battery 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 marked, rather than randomly guessing
**2. Charging Time Estimation**
– Displays a lightning icon and estimates the time needed to charge when a device is plugged in
– Automatically displays “Charged” after charging is complete, rather than remaining in “charging” indefinitely
**3. Quick Judgment of Whether to Charge**
– The top row of the summary window directly gives a conclusion: “No need to charge” or “Magic Trackpad is only 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

*Bluetooth Low Energy (BLE) Devices:*

– 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 the Mac is plugged in but not charging: optimization for 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, plain text, text with 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 drop below the threshold
– The Mac internal battery is also monitored
**8. Minimalist and Non-Distracting**
– Supports pure menu bar operation (no Dock icon), or normal window mode
– Can be set to automatically start on boot
– Follows the system’s 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 registration required, 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 application
– The application can automatically download, start, and stop the assistant, without manual configuration
Version 10.0.1 Update Highlights:
– Magic Battery records each device’s consumption rate and alerts you when it will be depleted—specifically, on which day of the week or at what time.
– Devices that are charging display a lightning icon and estimated charging time, and after charging is complete, it displays “Charged.”
– The menu bar popup explains why your Mac is plugged in but not charging.
– Polish, Korean, and Dutch language support has been added.
– The help menu item is restored to normal usability; in menu bar mode, the main window can always be opened.
