Magic Mouse disconnects

My Magic Mouse disconnects (turns off) after 5/10 seconds after connecting it to my Mac. I have to lift the mouse and click the mouse button in order to turn in on again.

I've had a look at some other posts but none of them seem similar to mine. The mouse rarely reconnects itself, you have to physically lift and shake (press) the mouse in order for the green light to light up again and the mouse to connect.

The mouse seems to disconnect (faster) when not in use (even for 1 second). If I keep using the mouse (fast moving the pointer) it seems to keep connected. I've tested with multiple batteries (Mac indicates 100% charged). It came with my 2012 Imac OSX 10.10.

Does anyone recognize this problem, or (even better) does anyone know how to solve it?

iMac, OS X Yosemite (10.10), Magic Mouse

I was having this same issue for quite a while. I have a number of mac's and I had at one point or another paired my mouse with multiple ones. Even though the notebooks were in a sleep state (with the lid closed) I believe the mac or the mouse would try and connect on some level. As an experiment, removed the mouse from all my macs and turned off bluetooth on those macs as well. The mouse is now working fine on my one mac. Hope this helps.

I had forgot about this thread...

After spending way too many hours trying to troubleshoot what I thought to be a bluetooth issue, on multiple Macs throughout the house, the issue turned out to be the AA batteries that I was using.

Now, I don't know if it's a bad design with the older Apple bluetooth devices, or if the battery manufacturer is to blame, however after swapping out all the Duracell AA batteries with Energizer batteries in all the devices, ALL bluetooth issues have been resolved. I have not had any bluetooth issues on any of the Macs in the past 12+ months since using Energizer batteries.

The Duracell battery is slightly smaller than the Energizer battery, and when stacking two of them, it was not making secure contact. This would be a non issue for anybody using the newer bluetooth devices with the integrated battery.

TL,DR - If you are using Duracell batteries and experiencing bluetooth issues, try swapping them out with Energizer batteries.

This answer is awesome!! Two years later and it fixed the issue I was having with my magic mouse 2! Previously I had to reboot my laptop in order to get it working again. Thank you.
