Laptop Battery life with i7-4710hq cpu

[stsaerox]

As the title says I want a new Laptop but my concern first is maximum performace in portable solution.

About battery now will it last enough to watch a movie in...

1. ...medium x264 quality and

2. ......10-15Gb file HD x264 movie video quality

I'm not asking for playing from a dvd since it consumes more battery and probably I'll remove it to add my "intell 520ssd 180GB" and already I've done my blue-ray drive external from my current laptop.

Probably I get this laptop:
Asus N551JK with gtx850m, 7200rpm HDD 1TB

There is a section about battery performance if you scroll down.

In short under load (maximum brightness) it lasts: 1h 16m

It's different cpu thought and seems like now nowadays, browsing is heavier that watching just a normal x264 episode. Considering this I might have a change.
If there isn't a change to watch my movies on the go I might get a desktop....

The laptop also is slightly different model and maybe new one.
