Why Haswell-Powered Windows Laptops Couldn’t Have Satisfactory Battery Life?

Many have been wondering why battery life on Windows-based laptops is so pitiful. When Apple joined the industry with the MacBook Air and later versions of MacBook Pro; it became quite clear that Microsoft’s operating system itself is to blame. A good comparison would be between MacBook Air (edition) and Surface Pro 2. Both are equipped with the same battery capacity and Haswell Core i5 processor, yet Apple’s thin laptop manages to give us twice the battery life.

So, what’s causing Window’s worse battery life?
While there’s no clear answer to this, the most sensible one is that Apple has more flexibility in making its software and hardware platforms work synergistically. The OS X is tailored really well to use less energy and make the most of available resources.

On the other hand, Microsoft Windows needs to works equally well on a wide range of hardware configuration. Consequently, Microsoft can implement low-level optimizations that could result in higher performance and longer battery life.

Despite the drawback, users of Windows laptops could still benefit from Intel’s latest Haswell architecture. It extends battery life by a few hours, which would be beneficial to users.
