I've had my Magic Mouse for a few years now, but recently, it seems like I'm changing the batteries every week, even though I turned it off when not in use for the last set I put in. Has anyone else noticed this or have any ideas? I'm going to try resetting the SMC of my Late 2011 MacBook Pro in case that somehow is causing more drain by perhaps not letting it go into sleep properly. The battery life of my Bluetooth Keyboard (2-battery) seems to be unaffected. I was about to use my Magic Trackpad instead last night, but the battery cap is stuck due to a leaky battery and I can't for the life of me get it open and it immediately disconnects.
