Everything you need to know to get Battery Monitor running on all your devices.
Installation
iPhone & iPad
- Open the App Store on your iPhone or iPad.
- Search for Battery Monitor and tap Get.
- Open the app after installing.
- When prompted, tap Allow to grant Bluetooth permission — this is required for the app to discover your other devices.
Mac
- Open the Mac App Store.
- Search for Battery Monitor and click Get.
- Launch the app. It will appear in your menu bar (top-right of your screen) — look for the battery icon.
- If asked, grant Bluetooth permission in System Settings → Privacy & Security → Bluetooth.
Tip: Battery Monitor runs quietly in the menu bar. You don't need to keep a window open — just click the menu bar icon to see all your device batteries at a glance.
Apple Watch
Install via the Watch app on your paired iPhone:
- Open the Watch app on your iPhone.
- Scroll down to find Battery Monitor under "Available Apps".
- Tap Install.
- Alternatively, open the App Store directly on your Apple Watch and search for Battery Monitor.
How it works
Battery Monitor uses Bluetooth Low Energy (BLE) to communicate directly between your devices. No internet connection is required, and no data leaves your devices.
The app automatically discovers and shows all your Apple devices that are signed in to the same iCloud account, are within Bluetooth range, and have Battery Monitor installed.
Note: Only your own devices appear. The app cannot see other people's devices. If a device is out of range, its last known battery level is shown until it reconnects.
Reordering devices in the menu bar (Mac)
You can customise the order in which devices appear in the menu bar dropdown:
- Click the Battery Monitor icon in your Mac menu bar.
- Long-press on any device row — a drag handle will appear.
- Drag the device to your preferred position.
- Release to save the new order.
The order is saved automatically and persists after restarting the app.
Why don't all my devices appear?
- Bluetooth must be enabled on both devices.
- Battery Monitor must be installed on the device you want to see.
- Devices must be nearby — within normal Bluetooth range (roughly 10 metres).
- Both devices must be signed in to the same Apple ID / iCloud account.
- On Mac, make sure Bluetooth permission is granted: System Settings → Privacy & Security → Bluetooth → Battery Monitor → Allow.
AirPods
AirPods battery monitoring is not yet available in Battery Monitor. Apple does not currently provide a public API that allows third-party apps to read AirPods battery levels. Once Apple opens this capability to developers, we plan to add full AirPods support.
