Is it an Apple Magic Mouse? Is it running off an iMac? Is it close the machine?
I had seen a wireless mouse that was slightly jerky to a MacPro that was a "bit 
out of range" and a "blocked signal".
So that's another thing to check as well….
Resetting SMC can also help with Bluetooth settings as well, so that's worth a 
try too.
Depending on your machine, you can see your SMC reset steps here as well:-

Hope that helps
