If you use Apple’s Boot Camp on your Mac, then you may be straining your battery when running Windows.

The Apple-given Windows drivers are found to be substandard, and they don’t allow Windows to take full advantage of the underlying hardware.

This means that this is a potential hidden cost of running Windows on a Mac because you’re losing battery life by doing so even if you run any Windows cleanup softwares therein.

There’s a battery-life test conducted on the brand-new 2012 MacBook Air and its 2011 counterpart by Engadget with OS X and with Windows 7 which shows that Macs have 70% less battery life when run on Windows.
