BatteryManager

A beautiful, native macOS app for monitoring battery health on Mac computers and connected iOS devices (iPhone/iPad).

Requirements

• macOS 12.4 or later
• For iOS device monitoring: libimobiledevice (installation instructions below)

Installation

Get the latest release from here

Install libimobiledevice (for iOS Device features)

To read battery information from connected iPhones and iPads:

# Install Homebrew if you haven't already
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install libimobiledevice
brew install libimobiledevice

Verify installation:

which ideviceinfo
# Should output: /opt/homebrew/bin/ideviceinfo (or similar)

Why is this better than coconutBattery?

• Completely free
• Subjectively better design
• Cleaner layout
• Smaller size, less RAM usage

Troubleshooting iOS Device Connection

If your iOS device is not detected:

1. Ensure libimobiledevice is installed:

   brew install libimobiledevice

2. Check if your device is detected:

   idevice_id -l

   This should show your device's UDID.

3. Verify trust status:

   • Unlock your iOS device
   • When "Trust This Computer?" appears, tap "Trust"
   • Disconnect and reconnect if necessary

4. Test manually:

   # Check basic device info
   ideviceinfo
   
   # Check battery info
   idevicediagnostics ioreg AppleSmartBattery

Please open a GitHub Issue once you've completed all of these steps and it still doesn't work

Known Limitations

• iOS device monitoring requires device to be unlocked and trusted
• Cannot monitor iOS devices wirelessly (Apple limitation)
• App Store distribution cannot include iOS features (uses private APIs via libimobiledevice and will never happen because it's expensive)
