More like quartered, from what I've read, i.e., reduced by 3/4.
Those gaming laptops which use full-power desktop RAM also weigh 8-10 lb and they STILL have terrible battery life. They are effectively unusable without being plugged in.
The battery life on the 14 inch model is 6+ hours of streaming video out of the box which isn't bad at all I think. The real question is how well it holds up over time. Also, it is one of the few laptops available with the new 10X0 video cards. I'm honestly probably going to hold out for the newer XPS 15s with kaby lake and the 1060 cards, which are supposedly out in January sometime.
The Razer Blade Pro also has a laughable battery life: 2 hrs 45 min for WEB SURFING. That's hilarious.
What that means is, probably less than an hour of battery life if you are actually gaming, which is the raison d'etre of this laptop.
Laughable.
What would people say if Apple made a high-end professional machine with half an hour of battery life? We'd never hear the end of it. Perfectly acceptable in the PC world, though.
Nice cherry-picking, though. The desktop-replacement gaming laptops category in general is indeed 8-11 pounds, just like I was saying:
If the ram's power use is the main problem, then that disproportionately affects low-power uses. There's no reason to think gaming would have a similarly crippled battery life.
Any idea how long the MBP lasts if you peg the GPU?
I wonder if it would be possible for the OS to consolidate "hot" memory into as few modules as possible and power down the ones holding relatively cold data when memory pressure is low.
