Apple magic mouse

[Rhyst21]

Hi guys i have a magic mouse and every 20 mins or so it keeps losing connection for around 30 seconds then reconnect's
The batteries say they have 71% so they are fine, Any ideas

Numbers can lie. Try other batteries. If not, are there any devices nearby that could interfere? E.g. Bluetooth or similar frequencies from a phone or something?

Any microwave ovens nearby? Microwave ovens, particularly cheap poorly-shielded ones, are notorious for screwing with everything in the 2.4GHz range (including WiFi and Bluetooth)

I had this infuriating problem for a while. I was using re-chargable batteries; after changing them to normal batteries the problem disappeared.

Are the positive ends of the batteries completely flat or do they have a tiny raised dot in the middle?

The flat end of a battery is its negative one.

Dangerous Theory is right.
I always have my iPhone on my desk, close to my mouse. I found turning off the bluetooth on the iPhone stopped this from happening.
Good luck!

Check and see how many Bluetooth devices are connected to your Mac. If 5 or more Bluetooth devices are connected to your Mac at the same time, the problem you described may arise. I limit the number of simultaneously connected Bluetooth devices to be smaller than 5.

As other people have suggested, a low battery level also causes such a problem.
