Q: Magic Mouse keeps disconnecting from bluetooth

My magic mouse (with all updates properly installed and with USB Overdrive properly uninstalled) has a problem connecting and disconnecting from the computer. When I use the mouse for a few minutes, it will all of a sudden be non-responsive, and within a couple of seconds the "Connection Lost" message appears on the screen. If I wait another minute, and click the mouse button a few times, the mouse will reconnect. This happens periodically as I am using the computer.

In the console logs, I get these messages:

10/31/09 6:06:20 PM kernel [0eb48f00][AppleMultitouchDevice::willTerminate] entered
10/31/09 6:06:20 PM kernel [0eb48f00][AppleMultitouchDevice::stop] entered
10/31/09 6:06:24 PM kernel [0ffa3600][BNBMouseDevice::init][30] init is complete
10/31/09 6:06:24 PM kernel [0ffa3600][BNBMouseDevice::handleStart][30] Done

10/31/09 6:06:24 PM kernel [09f11680][AppleMultitouchDevice::start] entered

The first message is when the mouse disconnects, and the rest are when it reconnects.

Does anyone have any suggestions?

    Thank you for your help.  In the past I was using rechargeable.  I got tired of the problem and switched to primary cells, but that did not fix the problem.  Mechanical definitely was an issue as the foil in the contact trick did help.  This is still an apple design flaw that was not fixed in 5 years - correction, they just came out with a rechargeable mouse to fix that problem.   I just now cleaned the contacts and tried the paper trick.  It has improved but a strong shock will disconnect it.

    Update - the improvement was not great, but with the paper trick after it disconnects it did not reconnect.  The lights were doing the double-flash until I tapped the mouse hard on the surface.  This is interesting as the LEDs were on so the mouse was getting power but did not reconnect.

    I can duplicate the problem.  I certain tap disconnects the mouse and it does not reconnect. I can watch the LED continue to flash holding the mouse bottom up and looking at it.  I just squeeze the mouse and it instantly reconnects.

    I am not going to take it apart as it is under warranty.

    If it is still under warranty, then get it replaced.  Build a few million of anything, and there will be defects in the manufacture.  Not ALL the mice can be behaving this way, even if there are more than a few, or this thread would be much longer than just 15 pages, and Apple support would be saturated.

    Just decided to google this issue with my MagicMouse, and there it is.  Checked my batteries and I have Kodak Gold, which when replaced with Duracells the mouse seems to be not disconnecting.

    I had been having the problem for awhile, never would have thought to check battery fitment.  You'd think that would be an exact standard.

    There is a visible difference between the two batteries, the Duracell has a bit more of a protrusion on the negative end.  The Duracell is also just slightly longer.  Doesn't seem like enough to make a difference, but could be.

    Yes, there are standards for the batteries within tolerances. 

    For the interest of everyone here, I put batteries and connected up three different wireless mice on my mac, including the microsoft mouse I bought at Costco for $15.

    Every mouse except for the apple mouse took huge hits and abuse with NO disconnect.  My magic mouse, with the paper around the battery, cleaned contacts, AND foil, took some slight bump into my silicon wrist-pad, but an energetic bump resulted in a disconnect. 

    THIS IS A DESIGN ISSUE.  don't waste your time hoping that apple fixes their design issue.  My five year old MM is identical.

    When I feel like wasting the time, I might go back to Apple since it is under warranty, but with the two fixes I mentioned, it works adequately and rarely disconnects unless it gets bumped. Still, it should not disconnect.  I found that once I fixed it, when I did a bump I paused in my workflow. I then realized that years with a defective mouse made me adapt my behaviour.

    This happened the same for me today. I was really annoyed with the Apple Mouse being disconnected for 10 consecutive times from my iMac. It really annoys me the worst. What I have done is that I have managed to move my mouse around to check whether it still works.

    Another problem for me is that after it disconnects, the battery level began to decrease. I don't know how could this happen.

    Dude - this is TOTALLY works.....just clean the little aluminum censors. Problem all gone - thanks Cojcolds and all other who mentioned cleaning the sensors inside the MM housing. What a waste of precious design time. So happy this is fixed - been dealing with this off and on for a few years now and finally got tires and looked it up on line - even bought new MM's to resolve the problem. THIS WORKS.

    what about those of us with an MM2 without a battery casing? I have tried 2 mice and they still sporadically disconnect & reconnect for no apparent reason.

    Then look for 2.4GHz radio interference.  Bluetooth uses 2.4GHz.

    • An over saturation of 2.4GHz WiFi base stations (apartment/condo complex)
    • Microwave oven (2.4GHz is the frequency that vibrates water, which is why no commercial radio service wants it, as rain, humidity, fog, etc... will interfere with long range communications, so the FCC gave it over to low power unlicensed spectrum).  So a Microwave oven that is leaking radio waves could interfere with 2.4GHz radios
    • Poorly shielded USB3 device or poorly shielded USB3 cable <https://www-ssl.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequen cy-interference-paper.html>
    • 2.4GHz cordless phones (could be a nearby neighbor)
    • 2.4GHz baby monitors (could be a nearby neighbor)
    • Something wrong with your Mac's Bluetooth antenna
    • Your own Mac WiFi (for example if you use 2.4GHz WiFi, and not 5GHz).  Less likely, but not unheard of.
    • An interference list from Apple <Potential sources of Wi-Fi and Bluetooth interference - Apple Support>
    • You can Google: "Mac Bluetooth interference" and most likely get some other ideas

    Put some paper under the battery it will keep battery stable and not to move.
