graphics card, you should expect some
compromise on battery life. The Lenovo
Yoga C940’s combination of a large
69,000 wHr battery and a 1080p, 60Hz
display give it an advantage. In our looping
video rundown test, the C940 15 lasted just
over nine hours. Of course, battery life
typically fell below two hours for gaming,
but we found that the C940 15 could get
through most of a workday with general
productivity use.

BOTTOM LINE

As with so many other laptops, the Yoga

C940 15’s worthiness is a matter of which

trade-offs you’re willing to make. HP’s

15-inch Spectre x360 has a similar

convertible design, but the version with

GTX 1650 graphics has a much dimmer

display (go.pcworld.com/dmds). Dell’s

XPS 15 7590 packs in 4K graphics and

even better battery life, but its

touchscreen variants get pricey and it’s

not a convertible design. Gaming-first

laptops like the Acer Nitro 7 will give you

even better performance, but they’re not

as nice to look at.

Of course, you could always go with a

MacBook Pro, but then you’ll miss out on all

those neat choices that make PCs like the

Yoga C940 15 more interesting in the first

place.

  niceties.
