I was enticed into buying a Dragonfly G2 3G0N9PA#ABG on the strength of the supposedly spectacular battery life.

Top of the line i7 fancy pants machine with stupidly high resolution screen and everything.

I'm not foolish enough to believe I could achieve the advertised benchmark times of 22 hours. With the i7 and UHD display you take a hit on battery life. I read somewhere it is in the vicinity of one third. Take away one third and say one fifth for optimistic advertising you are still sitting on 11 hours.

With the screen on minimum brightness, every power setting option set as low as I can get it (e.g. max processor state: 30%), and not doing any processor demanding work I feel lucky to get 6 hours use out of it. I'm doing light coding work, i.e. working with text documents, and have maybe a dozen browaser tabs going, and sometimes a USB mouse.

To give you an idea of what I actually get, here are some figures from the Windows Battery Report.

Pretty damn sad ultrabook if you cannot even get a day's work out of it.

Don't buy one. All promise without the satisfying follow through.
