How to Check Magic Mouse and Trackpad Battery on Mac

Your Magic Mouse gives you a low-battery warning right before a deadline, never after one. macOS shows an exact percentage for every Apple wireless accessory — mouse, trackpad, and keyboard — in three places. Here's where to look on macOS 13 Ventura, 14 Sonoma, and 15 Sequoia, plus the charging quirks worth knowing before the percentage hits zero.

The quick check: Bluetooth settings

1. Open System Settings → Bluetooth.
2. Look under My Devices. Every connected Apple accessory shows a battery percentage right under its name — Magic Mouse, Magic Trackpad, and Magic Keyboard alike.

The number is exact, not a four-bar estimate, and it updates while the pane is open. Third-party Bluetooth mice appear in the same list, but most don't report battery to macOS — if there's no percentage under the name, the device simply doesn't send one.

Faster: Control Center and the menu bar

You don't need to open System Settings every time:

• Control Center: click the Control Center icon in the menu bar, then click Bluetooth. Each connected device lists its charge level next to its name.
• Menu bar icon: open System Settings → Control Center, find Bluetooth, and choose Show in Menu Bar. From then on, one click on the Bluetooth icon shows every device with its percentage — the fastest readout macOS offers.

Terminal users can pull the same numbers without touching the mouse. This is read-only — it changes nothing:

When macOS warns you

macOS posts a notification when an accessory's battery runs low, and again when it's nearly empty. Don't wait for the second one: the Magic Mouse in particular gives you little runway once the first warning lands, and it can't be used while it charges. If you want an earlier heads-up than Apple's, the menu bar readout above is the practical answer — glance at it when you sit down, and plug in anything under 20% before a call or a long session.

Charging quirks: mouse vs trackpad

All current Apple accessories charge from a cable plugged into your Mac (Lightning on older models, USB-C on the newest). The experience differs sharply by device:

• Magic Mouse: the port is on the underside, so the mouse is unusable while charging — it lies on its back like a stranded turtle. The consolation: about two minutes of charging buys enough power to get through a meeting, and a full charge lasts around a month. Plug it in when you step away for coffee.
• Magic Trackpad and Magic Keyboard: the port is on the edge, and both work normally while charging — plug in and keep going. They also pair automatically with the Mac they're cabled to, which doubles as a fix for connection trouble.

A cabled accessory shows a charging indicator next to its percentage in Bluetooth settings, so you can confirm the cable is actually delivering power.

Using the older generation of accessories — the original Magic Mouse and Magic Trackpad that run on removable AA batteries? They report percentages in exactly the same places, but there's no charging: when the number gets low, swap in fresh batteries and the reading resets. Rechargeable AAs work fine, though their reported percentage tends to drop more abruptly near the end, so treat anything under 30% as "swap soon."

Mouse dead right now?

If the battery already hit zero mid-task, remember every Mac laptop still has its built-in trackpad, and any USB mouse works instantly with no pairing. For recurring connection trouble after charging, see the Magic Trackpad pairing fixes — the same steps apply to the mouse.
