XPS 13 9350 Skylake FHD vs QHD battery life

Hi everyone. Trying to figure out the tradeoff between resolution and battery life.

Would you mind telling us what you're seeing in real life, what resolution you have and other specs, and what your usage load is like?

I'm most interested in wifi, websurfing and taking notes but I'm sure others are interested in other patterns.

Thanks!

 

Broadwell laptops showed about 9 hours on FHD, 6 hours on QHD.

Moving to skylake will not affect those battery life numbers.

Thank you. I had been more optimistic cause there were some Broadwell reviews of 7.5 hours with QHD, 10 hours on FHD, and then Skylake was supposed to be 20% more efficient so I was hoping maybe 8.5 hrs QHD, 11-12 on FHD, in which case I could go for the QHD. But at 6 hours it's not as interesting. Makes this a very tough decision!

Thanks so much for the feedback.

 

6 hours or 7.5 hours (QHD)
9 hours or 10 hours (FHD)

Those numbers are practically the same; depending on the workload being used for the testing. they're all within the same ballpark of each other.

As for Skylake being more efficient... yes it is, but it's only more efficient on power consumption for the CPU itself. Meanwhile, the CPU component only accounts for about 10%-20% of the overall laptop drain. The biggest power-drain component on any laptop will be the screen (about 50% - 70% of overall power drain). So sorry, you're not going to get 20% more efficiency on overall laptop power drain... just the CPU component.

 

That kind of makes sense in line with its bigger brother the XPS 15 (9550). The ones with 4K setup appear to be in the 4-5 hours battery life from what I hear. The discrete GTX 960M is also part of that big drain I'm guessing.
