How is the battery of the Dell XPS 15 9550 4k?

[Elgauly]

I want to buy the new laptop Dell xps 15 9550 4k but I thought how is the battery on this laptop?
I use 3D engines a lot and like unity, unreal engine and a lot of photoshop, I am very curious how long the battery can carry.

Thank you in advance

Based on our writers' review of that model, it lasts for just around 6.5 hours at max brightness and a light-moderate work load.
