Lenovo Yoga C640 review: The battery life blows us away

    At first look, it’s simple to dismiss this explicit mannequin of Lenovo’s Yoga C640, a Best Buy unique with a comparatively anemic dual-core i3 Comet Lake CPU, a puny 128GB SSD, and a $600 price ticket. That mentioned, this glossy convertible (formally the Yoga C640-13IML) has an ace up its sleeve: a beefy battery that simply goes, and goes, and goes.

    While this made-for-Best Buy system isn’t an awesome decide for customers seeking to course of 4K movies or crunch large numbers (there are different Yoga C640 configurations higher suited to such CPU-intensive duties), it might be an awesome match for customers in search of a flexible 2-in-1 that may go all day lengthy with out an AC wire.


    Lenovo presents three versions of the Yoga C640-13IML (we’ll simply name it the Yoga C640 from right here on out) on its web site, together with a $850 model (or $770 after reductions) with a 10th-gen Core i5-10210U processor, 8GB of DDR4 RAM, and a 256GB strong state drive, and a $1,000 mannequin ($910 with rebates) with the identical RAM and SSD however an upgraded i7-10510U CPU. There’s additionally a $1,050 configuration that ups the RAM on the Core i7 model to 16GB. All three fashions include the identical touch-enabled 13.3-inch Full-HD IPS show.

    Our assessment model (81UE000WUS) of the Yoga C640-13IML isn’t listed on Lenovo’s web site; as an alternative, it’s a $600 Best Buy unique that’s significantly cheaper (and, consequently, much less highly effective) than the opposite three fashions.

    Here are the main points:

    • CPU: Dual-core Intel Core i3-10110U (Comet Lake)
    • Memory: 8GB DDR4
    • Graphics: Integrated Intel UHD Graphics
    • Storage: 128GB SSD
    • Display: 13.3-inch 1920×1080 IPS, touch-enabled
    • Webcam: 720p, dual-array microphone, bodily digicam shutter
    • Connectivity: One SuperSpeed USB 5Gbps (previously often called USB 3.2 Gen 1) Type-C port, two SuperSpeed USB 5Gbps (previously often called USB 3.2 Gen 1) Type-A ports, combo audio jack
    • Networking: Wi-Fi 5 (802.11ac)
    • Biometrics: Fingerprint reader
    • Battery capability: 60 Watt-hour
    • Dimensions: 12 x 8.1 x 0.7 inches
    • Weight: 2.88 kilos (3.22 kilos with AC adapter)

    Overall, this a typical configuration that we see in price range laptops. The dual-core 10th-gen Comet Lake Core i3 CPU is completely able to on a regular basis computing duties resembling internet shopping, Office, and light-weight photograph enhancing, though it’ll begin to chug relating to demanding multi-core operations like video processing or crunching databases. The 8GB of RAM presents a good quantity of headroom for multitasking or juggling a number of browser tabs.

    The 128GB SSD will get cramped awfully quick. Once you take into consideration Windows 10 and different apps pre-loaded onto the C640, the drive solely has about 77GB of free house left. If you retailer so much domestically, you may need to spend money on an exterior exhausting drive or cloud storage.

    Physically, the 0.7 inch-thick and a pair of.88-pound C640 is about the identical dimension and weight as different 2-in-1 programs in its class. The fingerprint reader is at all times a pleasant bonus. WWhile Wi-Fi 5 networking is normal for laptops on this worth vary, simply do not forget that you received’t be capable to reap the benefits of the improved velocity and effectivity options supplied by cutting-edge Wi-Fi 6 routers.
