The Magic Mouse is truly one of Apple's better inventions, albeit not too well known. A multi-touch mouse is in my mind, simply genius. The sheer brilliance of the idea aside, the bluetooth mouse provides a sensational experience. Put it this way, 30 per cent of the pleasure of using a Mac is contributed by the hardware. ( Magic mouse contributes the majority of that number )
The seamless, multitouch surface of the mouse, also functions as the button and is capable of detecting intuitively a swipe, a tap, a pinch, a double tap, a click, a scroll or even a resting hand and also how many fingers were used to do it. In addition to this, if put through the right software it can also double as a trackpad. However there is a tiny flaw. Battery.
It drains enormous amounts of battery. Within a few weeks of average consumption your "long lasting" battery will fall down to 10 per cent or so. The obvious solution ( aside from the tedious task of frequent battery replacement ) would be the heavily advertised Battery charger. Although not a bad idea, it is essentially, a hyped up pack of six rechargeable batteries and a charger. What I am about to tell you however is simply a trick, to change the "few weeks" of battery like to a few months and if done regularly enough maybe even half a year.
Switch off the mouse at night. ( Or when not in use ). You may not believe me now but switching the mouse off at night or otherwise actually somehow seems to increase your mouse battery. Not much, but it does by 5-10 per cent each time. Even if you don't believe what I am saying, surely turning your magic mouse battery off can't do any harm. And in any case, you'll see it for yourself.
