Magic Mouse keeps losing connection

For the past several days, my magic mouse keeps losing connection to my MacBook Pro, and most of the time it won't even connect at all. I thought the batteries needed changing at first, but that didn't help either. I keep going into my Bluetooth settings to try and manually connect it but, again, it didn't work. Can anyone suggest ways to try to fix this problem?

I had this problem too, turns out a slight design flaw with the mouse is that smaller batteries come loose and power is lost, so the bluetooth dies. You'll probably find that it loses connection when you're moving it around quite a lot, in particular, when you lift it up off of the desk and put it back down again. See, different brands of battery tend to be ever so slightly varied in size, and smaller ones tend to be more 'loose' in the mouse and an be shaken loose when moving the mouse around.


The best solution (the one which worked for me) is to grab a set of Apple's own rechargeable batteries from their store as they are just the right size to fit in the mouse without ever being shaken loose.


If you can't do this, some people find that wedging a bunch of paper between the two batteries and between the batteries and the mouse door can help keep them in place.


I hope this solves your problem as it has mine. 🙂

Apple Your Magic Mouse is JUNK! Using redneck ways of working around design flaws..add foil to the negative side, and a piece of tape, or paper to the battery door. If the mouse is designed to work with a specific battery(Apple's rechargeable batteries) then apple should supply them with the charger.


At $70.00, the Magic Mouse should not be acting this way!!

I would be more then happy to trade Apple my Wireless Keyboard and Magic Mouse for a wired set.

I have had same issues of the mouse behaving iradkic (jittery), losing connect etc.

the issue was my iPhone 6. if its in within 3 ft of the mouse, then the mouse starts to stutter and stall.

as the iPhone gets closer, the worst the symptoms get.


Move the mouse to more that 3 ft and presto all is well again with my magic mouse and mac-book 13 (2014) with Yosemite OS.

I've also did the pram clear thing, but its just kept coming back like a bad cold.


Clearly a issue with too much bluetooth in the same area

Had the same problem for months and tried everything suggested here without success. I decided I needed a new mouse plus mobee charger. Problem persisted and out of desperation I reverted to a wired mouse intending to return both Mouse and Mobee for a refund. BUT told by Apple technical support to unplug computer then depress the power button for ten seconds (with computer still off). I was baffled as to how this could work given that no power was going to the system but did as I was told. The techie guy (thank you Nuno) explained it in a way which made sense at the time. Anyway, turned it all back on and IT WORKED! 100% of the time, no connection problems at all.

I too have had this issue, and the only things thats worked for me has been doing both of the following.


1- ( and I cannot recommend this as it's not how the mouse is supposed to be used) however I cut two small pieces of tin foil about a half inch thick and wedged them in between the negative connecter and the batteries.


2- I took a piece of cardboard and wedged or shimmed it between the batteries and the compartment that holds them in preventing the batteries from moving around within the mouse and thereby preventing loss of connectivity between the batteries and the connectors. Between the two of these, my problems seems to be solved. i spoke to apple about this and they were willing to replace my mouse, however because I'm not near an Apple Store. i would have to lay out $75 Canadian until they got the old one back and then wait for them to refund me. It takes them too long to do thi and I don't have the $75 right now.

I think I found a work around that I haven't seen used up to this point :

1. The moment your mouse disconnects and you get the overlay (mouse disconnected message), go right over to your WiFi bars (NOT your bluetooth)

2. Turn WiFi off !!!


3. Click on your magic mouse like 4 times in rapid succession, MBPR should re-pair with the mouse at this point rather quickly.


4. Turn you WiFi back on


5. Have a great day now that you only had to click on 2 things and never touch bluetooth settings or system pref., etc.

For me the problem was definitely related to the fact that some of the double A batteries are smaller than others. Apples rechargeable batteries are two millimetres bigger than some of the standard panasonic or energizer batteries which are 2 millimeters smaller than some of the other standard duracell and other energizer batteries. What this means, and I wrote about it here http://blei.org/blog/?p=88 is that sometimes you can buy a double A battery thats a bit smaller than others, and whats happening is that they are moving around within the chamber and losing touch with the contact points. I tpook some information off the web here http://macs.about.com/od/tipstricks/qt/Fix-Magic-Mouse-Disconnects.htm and took a small piece of cardboard and shimmed it in the back oif the battery case to hold the batteries firmly against the contact points, and I stoipped having signal dropout completly

Within this and other similar posts, it is regularly mentioned that you should buy good quality batteries and in this respect the brands most mentioned and generally acknowledged as such are Apple, Eneloop, Energiser, and Duracell.


You should not buy at dime a dozen stores or doubtful outlets for fear of getting fake or substandard batteries. It is these kinds of batteries that are likely to be of irregular size and thereby provoke the kind of problem you mention.


With rare exceptions there is nothing basically wrong with the Magic mouse, and all the talk of stuffing cardboard and bits of foil in it is quite unjustified. Of course someone will pop up and say the opposite but it would be a good bet that the need to enable the mouse this way is almost invariably due to using low grade batteries.

[. . .] there is nothing basically wrong with the Magic mouse [. . .]

Have you witnessed any of Judith Scheindlin’s cases in which she’s ruled on that adverb?


[. . .] it would be a good bet that the need to enable the mouse this way is almost invariably due to using low grade batteries.

The implicit or explicit point of several contributors to this thread is that the Magic Mouse’s battery compartment should have been designed to work perfectly well with AA batteries of any brand. I’ve had umpteen devices that have done so, including a mouse or three, and most of those devices have cost me a lot less than the Magic Mouse. Nevertheless I like the thing for what it can do, so I’m happy to keep using mine—with Energizers.

All things considered though, it seems pretty silly to have to tweek the mouse like this. I had the Apple batteries in mine and still had the same problem.

surely a company like Apple could have done better. I don't use mine any more. It was too problematic. Love the style and feel but that was as far as it went for me. An elcheapo much better which I found disappointing.

I have the same problem:


1) Using the Magic Mouse on an iMac Pro OSX 10.9.5 and a Mobee battery pack purchased from the Apple store,

2) Using a second mouse and second battery pack and having the same problem,

3) The problem persists on standard batteries (although I admit didn't stick paper in them),

4) The mouse is about 12 to 18 inches from the laptop,

5) My iPhone bluetooth is off.


Yes, it is more than annoying!


Thank you for suggestions.

Jan 3, 2015 8:26 AM in response to CZShadow

Thank you, that was an interesting suggestion. I am using the Mobee rechargeable batteries one can't easily stick a washer in there, but your suggestion caused me to look further.


I pulled the battery pack in and out and got a different charge reading every time, always around 7% to 10%. So I looked closely at the contacts and saw a pin-***** sized contact point on the battery pack where the nickel plating looked worn off and it appeared you could see brass underneath. I "erased" both the battery contacts and the mouse contacts with a pencil eraser, put the battery back in and the charge read 74%! The mouse works perfectly now!


I will see if that fixes the other mouse too when I go home. THANK YOU for taking time to help me.
