Both the Magic Mouse and the Magic Mouse 2 have a few problems that users have noted. For the first-generation Magic Mouse, short battery life and Bluetooth connection issues are the most often cited. And for the Magic Mouse 2, the inability to recharge the mouse while using it, along with Bluetooth connectivity issues.

We're going to address all of the cited issues, and show you how to get the best performance out of your Magic Mouse, no matter which generation of the mouse you're using. If you need help with Magic Mouse tracking errors, there's a fix for that, too.

Fix First Generation Magic Mouse Bluetooth Disconnects

There can be numerous reasons for a Magic Mouse to drop the Bluetooth connection, but the most common reason is a loose battery terminal contact inside the Magic Mouse.

The major cause of the Magic Mouse dropping the Bluetooth connection can be traced to the Magic Mouse's battery compartment, and what appears to be a weak design for the battery contacts. Essentially, it's possible for a small jolt, such as lifting the mouse to reposition it, to momentarily cause the battery terminal in the Magic Mouse to move, thus breaking the electrical connection. No power, no Bluetooth connectivity.

This may be the result of a weak spring in the contacts, as well as a poor contact design. Either way, the fix is simple.

  1. Remove the batteries from the Magic Mouse.

  2. Cut a small piece of aluminum foil about ½-inch square in size.

  3. Wrap the aluminum square around the negative terminal of the battery.

  4. Re-insert the batteries into the Magic Mouse.

The extra thickness of the aluminum foil produces a bit of additional force wedged between the battery and the spring-loaded contact. This makes the battery less likely to be jarred away from the contact when you move the Magic Mouse around.

This may be enough to fix most Bluetooth disconnect problems, but if your Magic Mouse still experiences an occasional disconnect, there's one more modification you can try.

  1. Remove the Magic Mouse battery cover.

  2. Cut a piece of paper into a rectangle about 1 inch by 1-½ inches.

  3. Place the paper on top of the batteries, roughly centered. Tuck any excess paper around the edge of the batteries.

  4. Re-install the Magic Mouse battery cover.

The extra paper acts as a wedge between the batteries and the battery cover, to help hold the batteries in place.

Fix Magic Mouse Bluetooth Disconnects: Any Generation

While the first-generation Magic Mouse had a strange battery-related Bluetooth issue, both the first- and second-generation Magic Mouse can suffer from more conventional Bluetooth problems, including having the connection suddenly stop working, be intermittent, or most frustrating of all, having the Magic Mouse show up in the Bluetooth device list, but never actually connect.

First-Generation Magic Mouse Battery Issues

The first-generation Magic Mouse made use of good old-fashioned AA alkaline batteries. This conventional power source soon earned the scorn of some users, who complained of very short battery lifetimes; some users were seeing less than 30 days of life out of a fresh set of AA batteries.

If you're experiencing unusually short battery life, there are easy ways to extend battery life and reduce battery costs.

Magic Mouse 2 Recharging Issues

One of the most common complaints about the Magic Mouse 2 battery is the inability to recharge the mouse while still being able to make use of it. But while it's an issue for some of us, it doesn’t need to be a reason to avoid the Magic Mouse 2; in fact, it could be a desirable feature, at least for those of us looking for a reason for a quick coffee break.

It's true that because the lighting port on the mouse is on its belly, you can’t use the mouse while it's being charged. But what's often overlooked is that 60 seconds spent recharging provides enough power for the Magic Mouse 2 to operate for one hour. Double the recharge time to two minutes, and the mouse can go nine hours before it needs to be recharged.

Apple contends that the Magic Mouse 2 can run for about a month on a full charge, so even if you forget to charge it up, a two-minute charging coffee break is all that's needed to get you through a normal workday, allowing you to recharge the mouse in the evening to a full one-month charge.
