Magic Mouse battery life?
The Apple rechargeable batteries in my Magic Mouse only ever last about a week before they run down. I thought they might be coming to the end of their life so I bought a new set - same result: freshly charged batteries never show in Bluetooth as more than 80% charged and fall to around 50% after a day. Has anyone else had the same experience? - could it be the Apple charger? Any thoughts gratefully received.
