The Lenovo Yoga C630 is the second Windows 10 PC to feature the new Qualcomm Snapdragon 850 processor (the other being the Samsung Galaxy Book2). Featuring a 13-inch full HD display and up to 8GB of RAM, what makes the Yoga C630 so intriguing is both its super-long battery life and its affordable price of around $800.

I've been using the Yoga C630 for the last month, and it is one of my favorite always-connected PCs (ACPCs) to date. That lower price comes with a few tradeoffs, but none are deal breakers.

The Yoga C630 differs from the Samsung Galaxy Book2 both in price and form. The Galaxy Book2 is a Surface Pro clone with a Qualcomm chipset but also runs $200 more than the Yoga C630. Granted, the Galaxy Book2 has a gorgeous, higher resolution AMOLED display and comes with a very good Samsung S-Pen, which helps justify that cost. This is the second ARM device from Lenovo, with the other being the decent Miix 630.

The Yoga C630 is mostly a traditional laptop design that can also flip into different modes including tent, screen-first, or tablet. It has the latest Snapdragon 850 processor, but unlike most Windows 10 on ARM devices, it has 8GB of DDR4 RAM instead of just 4GB. That extra bit of RAM helps when running browsers with multiple tabs open or many apps in the background.

Pen support is here but the stylus is not included, and Lenovo is not pushing this hard as an inking device. Lenovo uses N-trig for pen technology (versus AES), so you can use a Surface Pen with it. But the accuracy and pressure-levels are mediocre at best.

The Yoga C630 looks a lot like a standard 2-in-1 laptop from Lenovo. That's a good thing, though, as many people often gravitate to such form factors, which are practical for productivity.

The Yoga C630 is solid with no flex in a sturdily-reinforced chassis. The keyboard deck has a nice soft-touch paint texture to it, making it warm and inviting and not cold like metal. The iron grey color scheme works well, looking professional and hiding fingerprints.

The hinges are a new style for Lenovo, deviating from the patented watchband design found on older Yoga laptops. The new hinges look great and are also a sweet spot for Lenovo's logo instead of the display chin. The hinges are stiff, which is what you'd expect for a 2-in-1.

Weight 2.65 lbs (1.2 kg)
At 2.65 lbs (1.2 kg), the Yoga C630 is on the lighter side for a 13.3-inch laptop, and its 12.5mm thickness (when closed) makes it one of the thinnest laptops around.

Overall, the Yoga C630 is conservative looking compared to flashier laptops on the market, but it's difficult to criticize it for being unsightly. The rounded edges and clean, minimalist look are a welcome change from busier offerings.

For ports, there are not a lot of options. There are two USB Type-C 3.0 ports for power, display and data, a headphone jack, and a power button. The ports work well enough, especially for charging, but you will need a Type-A adapter (not included) to use any older peripherals.

Lenovo added a pinhole LED light on the side to let you know the laptop is charging. The power button on the side also has a white LED and it turns bright orange when the laptop has 20 percent or less battery.

While the price for the Yoga C630 is great, the display takes a hit. The Full-HD resolution is fine for this class of device and screen size, but it's clear this is a lower-quality display than most Ultrabooks.

Whites are a bit yellow – a common theme with Lenovo screens – and the colors are not very punchy. Brightness is decent, nearing 300 nits, but there is no HDR-type support, which is found in the Windows 10 October Update and beyond. Touch responsiveness is excellent, but the inking requires a lot of pressure to activate, and the drag on the display is not nearly as smooth as higher-end PCs. Clarity of the Yoga C630 display is excellent, as well, and I have no complaints using it day to day as my work laptop.

Lenovo is often regarded as the king of keyboards, and that applies to the Yoga C630. The familiar key style with an adequate amount of travel and consistent actuation make this an excellent typing experience. The keys have two-stage backlighting controlled via the function key – a standard Lenovo practice – and are quite visible in low-light situations.

The trackpad is spacious, glass and it uses Microsoft Precision drivers. The lower corners click and overall this is a solid trackpad; it's not the best but far from the worst.

There is also a Goodix-branded fingerprint reader for bio-authentication. While an infrared facial recognition camera would be better, a fingerprint reader is a good alternative that also saves buyers some money. It can be used to wake the Yoga C630 and has consistent and reliable reads.

I believe the Qualcomm Snapdragon 850 will blur the lines between Intel (x86) and Qualcomm (ARM) performance. The 2.96GHz Snapdragon 850 is the first specifically-tuned ARM chip for Windows 10, and it's a welcome improvement over the previous Snapdragon 835, which was almost good enough.

There is the recently announced Qualcomm 8cx processor, but that chip is not displacing the Snapdragon 850. Instead, it is a higher-tier one for even more powerful devices (and likely more expensive ones), like how Intel has Core i5 while also selling the Pentium chip. The Snapdragon 8cx is also not due until the fall of 2019, giving the Snapdragon 850 some breathing room.

Evaluating performance is tricky with ARM since it just surpasses Intel's lower-end processors for single-core but trounces those same chips for multi-core, due to the different architecture. Geekbench 4.3 can now benchmark Windows 10 on ARM, as well as 32-bit applications running under ARM.

If you are sticking with Windows 10 native apps including the Edge browser, Office 365, Mail, Weather, News, and about 95 percent of the apps on the Microsoft Store, the Yoga C630 feels very much like a Core i5 on the Surface Pro 4 for multi-core tasks. For single core, it's going to beat the Surface Go barely.

For those who don't like the Microsoft Edge browser both Chromium and Firefox are going to support ARM64 very soon. That means those two will run natively on this PC and perform just like Edge, but with all the things you like about either Chromium or Firefox.

Where the Qualcomm Snapdragon 850 still struggles is the emulation of Win32 apps – things that you download from the internet like Google Chrome or an Adobe app. Those will run, just more slowly.

Performance is better than an Intel Atom processor for single-core, but near what the Surface Go gets for multi-core.

I have had no issues running the Snapdragon 850 for my work, which includes web browsing (Edge), mail, Twitter, Microsoft Word, Skype, Slack, and a few other productivity-based applications. It feels very similar to a Surface Go except that native ARM apps perform much better with multi-core on the Yoga.

Battery life is incredible.

Gaming is also not a strong suit for the Yoga C630, although it can run some casual titles with ease.

Lenovo uses a 128GB Samsung eUFS (KLUDG4U1EA-B0C) drive which yields around 800 MB/s for read and over 200 MB/s for write. It's not nearly as fast as a proper NVMe solid-state drive (SSD), but it also doesn't feel like it is slowing down anything either.

The real winner for the Yoga C630 is battery life. Lenovo promises 22 hours, which is generous, but that sizeable 61WHr battery does give me easily around 15 hours of real-world usage. It's almost painful to count as the Yoga C630 goes and goes. It's so far, the longest-running Windows 10 PC – either ARM or x86 – that I have used. The battery life is incredible.
