Lenovo Yoga C640: The battery life blows us away

At first glance, it’s easy to dismiss this particular model of Lenovo’s Yoga C640, a Best Buy exclusive with a relatively anemic dual-core i3 Comet Lake CPU, a puny 128GB SSD, and a $600 price tag. That said, this sleek convertible (officially the Yoga C640-13IML) has an ace up its sleeve: a beefy battery that just goes, and goes, and goes.

While this made-for-Best Buy system isn’t a great pick for users looking to process 4K videos or crunch big numbers (there are other Yoga C640 configurations better suited for such CPU-intensive tasks), it could be a great fit for users looking for a versatile 2-in-1 that can go all day long without an AC cord.

SPECS AND FEATURES

Lenovo offers three versions of the Yoga C640-13IML (go.pcworld.com/3vrs; we’ll just call it the Yoga C640 from here on out) on its website, including an $850 version (or $770 after discounts) with a 10th-gen Core i5-10210U processor, 8GB of DDR4 RAM, and a 256GB solid-state drive, and a $1,000 model ($910 with rebates) with the same RAM and SSD but an upgraded i7-10510U CPU. There’s also a $1,050 configuration that ups the RAM on the Core i7 version to 16GB. All three models come with the same touch-enabled 13.3-inch Full-HD IPS display.

Our review version (81UE000WUS) of the Yoga C640-13IML isn’t listed on Lenovo’s website; instead, it’s a $600 Best Buy exclusive (go.pcworld.com/600x) that’s considerably less expensive (and, consequently, less powerful) than the other three models.

Here are the details:

CPU: Dual-core Intel Core i3-10110U (Comet Lake)

Memory: 8GB DDR4

Graphics: Integrated Intel UHD Graphics

Storage: 128GB SSD
