You've asked this before - and the answer is the same.  You're not going to find one system that meets all your criteria.  You need to prioritize the essentials and compromise on the others.

If you value battery life, and are in the market for an ultra-lightweight system like the Surface pro, there are plenty of options from all manufacturers.  You'll find the XPS 13 line the most direct competitor.  What you will not find at this level is high performance graphics.  It's physically impossible to integrate the level of GPU you want in a size/weight package this small.  There are plenty of options at this class of system, however beyond the surface pro.

If you want high performance at the 15" or 17" level, there are also plenty of options.  The Dell XPS 15 and 17 models have everything you want here as well - but you won't find 5-6 hour battery life with the GPU you want; the GPU is much more power-hungry than the integrated graphics in the ultraportable system, and it's just not possible to fit enough battery cells into a system to allow that level of battery run.  Beyond that, most manufacturers of systems at this level know that users want high-speed CPUs and GPUs -- and the only way to power these is an AC adapter.  The battery becomes a compromise, able to power the system but not at full speed, so it's a secondary design consideration.

Because if its design, the Apple Macbook Pro 16" probably fits best, assuming you're running MacOS, which is more power-efficient than Windows 10.  And even it comes with a downside:  yes, it has a larger battery largely because of its engineering.  The big downside:  you can't replace it when the time comes;  it will require a trip to an Apple service center, because it's glued into the system rather than being easily replaced with a simple Torx screwdriver, as most Windows notebooks are.  And of course, it comes with the Apple tax included:  you'll pay much more for the equivalent hardware than in an XPS/Legion/etc. system
