If you own a Windows 8 Ultrabook or laptop, then beware: according to Michael Prospero of LAPTOP Magazine, the average battery life of each category has gone down ever since the arrival of Windows 8 products.

Using a variety of products for testing (such as the Dell XPS 12, Lenovo IdeaPad Yoga, Sony VAIO Duo 11, and Toshiba U925t), Prospero concluded that the average battery life for ultraportables sat at 5 hours and 9 minutes. Meanwhile, the Thin & Lights category fell to 5 hours and 7 minutes on average.

There could potentially be several different issues causing the low battery life, from the touch-screens, the operating system, or the various software that comes pre-installed. Nonetheless, considering that ultrabooks are supposedly known for their long battery life (thus the reason behind the drastic change from removable batteries to internal batteries), this definitely proposes an issue in today's electronics.

This isn't to say that the problem will remain: even with smartphones, many OTA (over-the-air) hotfixes and updates have been applied in order to increase battery life. It remains to be seen whether Windows 8 will fall in line with this trend though, or if the drop in battery life can be pinpointed to other reasons.
