The Magic Mouse charges through a Lightning port on its underside

Your Apple Magic Mouse has a small Lightning port on the bottom. This is where you plug in the cable to charge it. The mouse comes with a USB-C to Lightning cable in the box, or you can use any Lightning cable you already own — the same kind that charges older iPhones and iPads.

The mouse does not have a visible battery indicator on the device itself, but your Mac will show you the battery level in the menu bar at the top of the screen. You can also check the battery by opening System Settings on your Mac, going to Bluetooth, and looking for Magic Mouse in the list of devices.

Key Takeaways

  • The Lightning port is on the bottom of the mouse, and you charge it by plugging in the USB-C to Lightning cable that came in the box.
  • A full charge takes about two hours and lasts roughly one month of normal use.
  • Your Mac shows the battery percentage in the menu bar, so you can see when the mouse is running low without opening any settings.
  • The mouse will still work while charging, so you do not have to stop using it during a charge cycle.

Step-by-step charging instructions

Step 1: Locate the Lightning port. Flip the mouse over. You will see a small rectangular opening on the flat bottom surface. This is the Lightning port. It is the same size and shape as the port on an iPhone.

Step 2: Plug in the cable. Take the USB-C to Lightning cable. The Lightning end (the smaller, flat connector) goes into the port on the mouse. The USB-C end (the larger connector) goes into a power adapter or into a USB-C port on your Mac or another device. Push gently until you feel it seat — it should not require force.

Step 3: Wait for the charge. Leave the mouse plugged in for about two hours for a full charge. You do not have to wait for it to finish before using it — the mouse works while charging.

Step 4: Unplug when done. Once the battery shows 100 percent in your menu bar, gently pull the cable straight out. Do not twist or bend it.

How to check the battery level on your Mac

The easiest way to see your Magic Mouse battery is to look at the menu bar — the row of icons at the very top right of your screen. You should see a small battery icon that shows a percentage. This updates automatically as your mouse charges and drains.

If you do not see the battery icon in the menu bar, you can check it another way. Click the Apple menu in the top left corner, then click System Settings. In the sidebar, click Bluetooth. Find Magic Mouse in the list of devices and look at the battery percentage shown next to it.

How long a charge lasts and when to charge

A fully charged Magic Mouse typically lasts about one month with normal daily use. This means you do not have to charge it constantly — most people charge it once a month or less. If you use your mouse heavily, you might need to charge it more often.

You will get a warning notification on your Mac when the battery drops to 10 percent. This gives you plenty of time to charge before the mouse stops working. You can charge it at any point — there is no harm in charging a mouse that still has battery left.

Troubleshooting a Magic Mouse that will not charge

If your mouse is plugged in but the battery percentage is not increasing, the problem is usually a dirty Lightning port. Lint and dust can block the connection. Turn off the mouse, then use a dry cotton swab or a soft, dry cloth to gently clean inside the Lightning port on the bottom of the mouse. Do not use liquid or force.

If cleaning does not work, try a different Lightning cable. The cable that came with your mouse might be damaged. If you have another Lightning cable at home — from an old iPhone or iPad — test with that one first before buying a new cable.

If the mouse still will not charge with a different cable, the Lightning port itself may be damaged. At that point, contact Apple Support or visit an Apple Store to discuss repair or replacement options.

What power adapter to use

You can charge your Magic Mouse with any USB power adapter that has a USB-C port. This includes the power adapter that came with your Mac, any modern phone charger with USB-C, or a standalone USB-C power adapter. You can also plug the cable directly into a USB-C port on your Mac itself.

The mouse does not require a high-power adapter. Even a low-power adapter meant for a phone will charge it fine — it will just take a bit longer. Avoid very old adapters or cheap third-party ones that do not have proper safety certification, as these can damage the cable or port over time.

Frequently Asked Questions

Can I use the Magic Mouse while it is charging?

Yes. The mouse works normally while plugged in. You do not have to stop working to charge it — just plug it in and keep going. The cable is long enough that you can move the mouse around on your desk while it charges.

What if I lose the Lightning cable that came with the mouse?

You can buy a replacement USB-C to Lightning cable from Apple or from most electronics retailers. It costs between $15 and $25. Any standard Lightning cable will work — you do not need an Apple-branded one, though Apple cables tend to be more durable.

How do I know if my Magic Mouse battery is fully charged?

Check the battery icon in the menu bar at the top right of your screen. When it shows 100 percent, the mouse is fully charged. You can unplug it at that point, though leaving it plugged in a bit longer will not harm the battery.

Why is my Magic Mouse battery draining so fast?

If your mouse is losing charge much faster than one month, the battery may be aging. Rechargeable batteries naturally lose capacity over time. If the mouse is more than three or four years old, the battery may simply need replacement. Contact Apple Support to discuss repair options.

Is it bad to leave the Magic Mouse plugged in all the time?

No. Modern rechargeable batteries, including the one in your Magic Mouse, are designed to handle constant charging without damage. If you prefer to keep it plugged in at your desk, that is fine — it will not shorten the battery lifespan.
