    I have been having this problem for about a month now, and reading the thread I am thinking this goes back to the cheap AA batteries I bought a month ago. Maybe they are shorter and don't connect well. Sometimes, my mouse will disconnect on/off up tp 5 successive times in a row. I want to throw it when it happens.


    I don't believe this is to a bluetooth conflict. This has just started happening, something had changed recently to cause this. I was hoping that it wasn't something breaking down in my Mac as I already have one bad riser, and montherboard could be slowly going.


    Can't believe how widespread this is and the posts have been since 2009, and still here we are.

    Try this:


    System Preferences----Bluetooth----Your Magic mouse---Gear icon---Show more info---add favorite


    it looks like this solves the problem:)

    I can confirm that removing the battery cover also works for me.

    mpayne - this keeps going because this is such a wonderful mouse -- until you hit the disconnect issue.

  • valfromottawa Level 1 Level 1 (0 points)

    I don't think it's a Bluetooth issue either. Every time this happened I had replaced a cheaper battery with the best kind ( at least claims to be)  such as the copper top ones, and it solves the problem I think it is a connectivity issue within the battery chamber.

    I've had the same problem for a while now but I seem to have fixed it.


    • Use a cotton bud and spray a small amount of WD-40 on one end
    • Carefully clean all four contact points within the mouse (i.e. where the batteries connect to at each end)
    • Use good quality batteries


    Haven't had a problem since!

  • Nick Radonic Level 1 Level 1 (0 points)

    Aye, there's the rub. What is a 'good quality battery'? Is it the chemicals - no. Is it the alloy of the metal on the ends - maybe. Is it the length of the tip of the battery, which leads to a different amount of retention force, and modification of the interference from the plastic battery holder case -- most likely.

  • smgs18 Level 1 Level 1 (0 points)

    When I say good quality I just mean something like 'Duracell', and not 'Heng-Tak' from the market.

  • JamoOz Level 1 Level 1 (0 points)

    Dudes.... It's the LENGTH of the battery. That's all it is, fix that - fix the cut outs. (Bar those caused by bluetooth clashes).

  • mpayne Level 1 Level 1 (0 points)

    Yeah. It's the length, or rather the thickness of the overlapping "substance" over the conductor, or something ike that.


    A 1/4 of a post-it note folded up to fit works a charm, so I'll keep buying the "Heng Shu" Brand. They're just fine. LOL


    It will always be a great mouse. Enjoy guys.

    Thansk to Qida's comment, I finally came to realize the battery length is the root cause.


    Yes, by adding foil does not sovle the problem in long term, though shortly the issue seemed gone. However, after a few weeks, the disconnect problem annoyingly returned. This time, no matter how much I fiddled around the thickness of the foil, the problem persisted. With hindsight, I think it is probably the foil that eventually further pushes the aluminum pad inside.


    Last week,  I dertermined to dump the foil solution, switched to Energizer Max battery (recommended from some other one on this forum). And, it is just like a magic, the long lasting frustration on the disconnect issue went away immediately and never returned since then!


    The joy of having the fullness of magic mouse back is undescribable.

    I was using a iogear GB412 bluetooth adaptor with a Mac Pro because the Mac Pro bluetooth is useless.

    The Magic mouse would connect ok but then i had the same disconnecting problem, at random.

    Changing batteries and bits of cardboard diddn't help either.

    What i did find was that i was using a USB extension and had the adaptor on my desk, thinking that the closer it was to the mouse the better the reception would be.


    Then i moved the adaptor away from my desk to the other side of the room... again using a USB extension.

    Since i moved it away from the desk it has not disconnected once. I use 2 32 inch tv's as monitors and have a fair bit of recording equipment in the room.


    With moving the adaptor away from everything i guess that there must have been some sort of interference from maybe the monitors or other eqiupment.


    I know this is not much help for laptop users but could be of use to someone... it worked for me.

  • cgmoorthy Level 1 Level 1 (0 points)

    I am still having the same problem even if I use Duracell battery. I am disappointed with magic mouse. Please give me a suggestion.

  • WeatherForecast Level 1 Level 1 (0 points)

    I'm having this problem too on my MBP 15 Retina. I've tried the suggestions in this thread including favoriting the mouse, and I get 20+ disconnects every day. I don't "buy" the battery idea as I don't use the mouse violently enough to shift the batteries inside ... and I can reconnect right away.


    This is maddening especially considering how well my wife's $20 logitech mouse stays connected to her PC. Apple??? See you at the store... I want a new mouse.

  • Nick Radonic Level 1 Level 1 (0 points)

    You don't have to 'buy' the battery idea. But take off the bottom of the mouse and take a look at the top of the battery where it goes into the contact slot.
