BTW, it’s 'possible to get 7 hrs battery life' from the Surface Pro by tweaking one of the processor settings, assuming you don’t need to use it for any highly intensive processing work such as video editing, 3D games, or image rendering etc.
I think 7 hours only possible if all your wireless radios are OFF, screen at dimmest & Power profile set to Power Saver, and it's completely idling.

Otherwise average non-intensive, can probably get 5hours as mentioned.

Another way is to completely switch off the Wacom Active Digitizer, which is a known battery sucker. That will make it more like the Acer W700, which lacks a digitizer but can last 7 hours.
