QuoteHere, you are saying that the Folio can provide up to 14 hours. I wouldn't bet on that, and would urge everyone considering the Folio to treat such predictions cautiously.
That isn't a prediction, its a measurement. Can't you see the difference? Notebookcheck's measurements are realistic. I bought an ultrabook after seeing a review here.
Of course you aren't going to get that all the time. If you are getting 5 hours of battery life out of *this* device, then you should just get a desktop, because you are doing something quite intensive with screen brightness all the way up or something.
If you are browsing the web or watching videos, then yes 14 hours is quite realistic. I assume depending on what you are doing it might even exceed that. You shouldn't need full brightness anyway. 20-40% brightness setting is good enough, and there's probably the side benefit that your eyes will thank you.
Maybe you are quite new to laptops and computers in general.
