Windows 8 on Kal El to sport battery life in days

If what NVIDIA is claiming is true, tablets powered by Kal El might just become the next big thing. It is tough, though, to believe that Kal El, with all its power, will eat up battery so slowly. In the past, the company has advertised the powerful quad-core Kal El with a battery life comparable or even slightly better than its predecessor, the Tegra 2 chipset.
   
The reason behind the claimed long battery life could be the manner in which the processors are made. If the ARM Cortex-A15 or the Cortex-A9 are produced with the <40nm method, they might be able to sustain an elongated battery life. This is probably the only way powerful quad-core chipsets can save such a significant amount of power.

On the other hand, Windows 8 could be a power saver too. Its Metro UI is borrowed from Windows Phone 7 and doesn’t require the same amount of power that the UI running on traditional Windows desktops does. This, is because the applications on Metro are simpler than the more complicated professional programmes of older Windows operating systems.

Yet, it remains to be seen how much battery Microsoft’s new OS eats up when it runs Metro and other traditional programmes side by side on the same tablet.
 
According to phonearena, "Intel said that ARM-based devices running Windows 8 won't support legacy Windows software, which is normal, since they are written for x86 machines, but now it seems that we'll be at least capable of running the current default programs and whatever new stuff ships with Windows 8, instead of only seeing the Metro-style interface of Windows 8."

Microsoft and NVIDIA are claiming that Windows 8 can run multiple programmes on powerful tablets using just an iota of the battery’s power. If this indeed is true, 2012 might just be the year that Microsoft makes a fortune!
