Lenovo Flex 5G review: A murky glimpse into the laptop’s future

Lenovo Flex 5G evaluate: A murky glimpse into the laptop computer’s future

“The Lenovo Flex 5G is held again by restricted 5G connectivity and mediocre efficiency.”

  • The perfect battery life we have seen
  • Stable construct high quality
  • Good keyboard and touchpad
  • Constructed-in 5G connectivity
  • Efficiency is mediocre
  • App and driver incompatibilities are a ache
  • 5G remains to be laborious to seek out

Two large PC revolutions are ready within the wings: 5G connectivity and ARM-based processors. The brand new Lenovo Flex 5G is a tool that seeks to launch us ahead right into a future that embraces each applied sciences.

Qualcomm’s new Snapdragon 8cx chip is the important thing, bringing each built-in 5G connectivity and sufficient efficiency to fight Intel Core processors. That makes the Flex 5G a Home windows vanguard towards Apple’s personal transition to ARM-based Macs.

However don’t get too excited. 5G’s roll-out has been sluggish, as has Home windows’ assist of ARM processors. Throw in a excessive beginning value of $1,500, and the Lenovo Flex 5G is being pressured to combat an uphill battle. Is the world prepared for Lenovo’s imaginative and prescient of the longer term?

5G connectivity

So, what’s the large cope with 5G? Merely put, it’s the subsequent technology of cellular broadband, and it’s taking the place of right now’s quickest commonplace, 4G LTE. It guarantees to supply web speeds that rival and even beat the connections most individuals have at dwelling and at work. However its roll-out throughout the nation has been sluggish.

You received’t discover it exterior of solely the most important cities. I needed to make a visit to Venice Seashore (by no means a foul factor) to check the Flex 5G’s connectivity, as there are only some areas in Los Angeles the place Verizon has protection, and none are very near my home. The protection is ultra-wideband, although, which theoretically ought to give the very best efficiency.

I say theoretically as a result of at the very least in Venice Seashore, I wasn’t in a position to obtain connectivity anyplace near the 2 gigabits per second (Gbps) speeds that ultra-wideband 5G guarantees. The perfect obtain pace I noticed (by way of Speedtest.internet) was 465 megabits per second (Mbps) and the quickest add pace I noticed was 51Mbps — I hoped to see nearer to 2Gbps obtain speeds and so seeing only a quarter of that was disappointing. And Verizon’s protection is spotty — Los Angeles, for instance, solely has a couple of areas with very restricted protection and the variety of cities coated by Verizon’s 5G community is fairly small.

I may stroll 10 toes in a single path or one other and drop to an LTE connection. This isn’t solely Verizon’s problem. T-Cellular, for instance, reaches extra areas with their 5G protection, but it surely makes use of sub-6GHz bandwidth that gives speeds extra similar to 4G.

It’s a lot sooner than 4G LTE, but it surely’s nowhere close to what 5G guarantees.

To see how that translated to actual life, I downloaded a 1.7GB file from OneDrive and hit a 44 megabytes per second (MBps) obtain pace. That’s a lot better than I’d see on 4G LTE, however once more, it’s nowhere close to what 5G guarantees.

I’d need to say that, in Venice, at the very least (and I did roam round searching for higher spots), Verizon’s 5G isn’t fairly as much as par. Maybe its sooner elsewhere, or maybe the Flex 5G’s modem drivers want tweaking. In any occasion, the Flex 5G will preserve you working at a quick clip wherever there’s 5G connectivity obtainable, however not practically as quick as it’s going to in the future present.

If it’s not apparent, as soon as 5G hits its stride will probably be a game-changer for computing. Right now, if you’d like a quick web connection — that’s, measured in gigabits per second and never simply megabits — you then’re caught utilizing Wi-Fi or a wired Ethernet connection. That ties you to particular areas and retains you on the hunt for a secure connection whenever you’re out and about. With a quick 5G connection, although, you’ll be dashing alongside wherever there’s protection — think about driving down the street and dealing with a quick web connection — which is able to ultimately be similar to 4G LTE right now. It’ll be in all places, which means you’ll lastly be unleashed from the Wi-Fi tether.


Qualcomm’s Snapdragon 8cx is the corporate’s newest ARM processor and the primary made explicitly for PCs slightly than primarily based on smartphone designs. Not solely does it need to compete with Intel and AMD, however the Snapdragon 8cx additionally faces the problem of working Home windows on ARM.

Previously, it hasn’t been essentially the most spectacular platform round in terms of pure pace. That’s as a result of most legacy Home windows purposes weren’t constructed natively to run on ARM, and as a substitute need to run in emulation. Efficiency is, due to this fact, the second most necessary issue behind connectivity in figuring out whether or not the Flex 5G is a viable platform for cellular staff.

Extra than simply being sluggish, many purposes received’t run in any respect on Home windows on ARM. That features a whole lot of the benchmarking purposes I sometimes use to check efficiency, which seems to be a great instance of the big downside with app compatibility. It’ll work with Microsoft’s Workplace suite, and it’ll work with Home windows 10 apps (to the extent that you just use any). And due to drivers that aren’t written to assist the platform, it’s hit and miss with peripherals.

For instance, our real-world Handbrake check video encoding received’t run on the Flex 5G. That’s a bummer as a result of this check provides one of the best concept of how nicely a processor will carry out when working demanding duties.

Extra than simply being sluggish, many purposes received’t run in any respect on Home windows on ARM.

I used to be restricted to Geekbench four and 5 amongst our efficiency benchmarks to get a glimpse into simply how a lot sooner the Snapdragon 8cx actually is. Going by these two exams, the brand new Snapdragon chip is certainly an improve from the Snapdragon 850 that preceded it. That doesn’t, nevertheless, make it a quick laptop computer by any means.

In Geekbench four, the Flex 5G managed three,322 within the single-core check and 11,348 within the multi-core check. That’s a significant bump up from the Lenovo Yoga C630 (which makes use of the Snapdragon 850), which scored 2,292 within the single-core check and 6,710 within the multi-core check. Clearly, the Snapdragon 8cx is far sooner. In actual fact, it even beat out the dual-core Intel 10th-gen Core i3-1011U within the Lenovo Yoga C640 within the multi-core check, which scored four,670 and eight,750.

In Geekbench 5, the Flex 5G hit 700 within the single-core check and a pair of,802 within the multi-core check. That beat the Yoga C640’s 486 and a pair of,155 and even competed with the 2020 MacBook Air‘s Core i5-1030NG7 that scored 1,140 and a pair of,770.

Does that make the Flex 5G a quick laptop computer? After all not. It carried out proper in step with these artificial benchmark numbers and equally to the comparability laptops. It was simply advantageous for productiveness duties, internet looking, watching video, and different makes use of that don’t ask an excessive amount of from the processor. If that’s what you employ your laptop computer for, you then’ll be glad with the efficiency. However when you want it to ramp up as wanted, you’ll be disenchanted.

Battery life

Longevity ought to be a energy of the Flex 5G due to the effectivity of ARM processors basically and the Snapdragon 8cx particularly. I anticipated good issues, and I wasn’t disenchanted.

In actual fact, I used to be blown away. The Flex 5G demonstrated one of the best battery life we’ve seen on a laptop computer, interval — it actually beat out each different machine we’ve examined.

I’ll begin with essentially the most spectacular outcome, specifically the video check that loops a neighborhood Full HD Avengers trailer till the battery runs out. Merely put, the Flex 5G was spectacular, lasting principally 28 hours looping the video (it got here up three minutes quick). That’s the longest we’ve recorded by nearly 5 hours, beating out the earlier finest Lenovo Yoga C640 that lasted round 23 hours. The Dell Latitude 7400 2-in-1 is the opposite laptop computer that’s lasted longer than 20 hours, at nearly 22 hours.

It is a laptop computer that may final you a number of days of use.

Within the internet check, the Flex 5G was simply as spectacular. It lasted for 17.25 hours, once more one of the best amongst all the laptops we’ve examined. The one different machine that got here even shut was the Microsoft Floor E book 2 at 15.5 hours, and the Floor E book three didn’t do practically as nicely.

Lastly, in our demanding Basemark internet benchmark check, the Flex 5G — you guessed it — bested all different machines. It lasted for a whopping 10.5 hours, which is — you guessed it once more — one other document among the many laptops we’ve examined. Now, granted, the Flex 5G didn’t break any pace data, however as quick because the laptop computer will run, it’s going to run for a very long time.

Be aware that these outcomes trounced the Yoga C630, which lasted 17 hours on the video check and about 11 hours on the internet looking check. Qualcomm’s claims of improved effectivity with the Snapdragon 8cx are nicely justified.

Clearly, it is a laptop computer that’s going to final you days of typical productiveness duties, internet looking, video watching, and the like. Even when you push the CPU — which isn’t saying a lot when it comes to total efficiency, after all — you’ll get a full day’s work, after which some.


The Flex 5G is a spitting picture for the Yoga C630, with only some adjustments to account for variations in ports. And whereas that makes for a really conservatively designed laptop computer — in accordance with Lenovo’s latest aesthetic — in its Iron Grey coloration that’s darker however not fairly black, it’s not a foul factor. Sure, there’s zero bling and so the laptop computer isn’t going to face out in a crowd, however some folks like that. It’s nowhere close to the HP Spectre x360 13, for instance, which is probably the epitome of chiseled, gem-cut design that screams for consideration.

Higher but, the Flex 5G is pretty nicely constructed. It’s an all-aluminum chassis that reveals only a little bit of flex on the keyboard deck however nowhere else. It has a strong really feel, which extends to the 360-degree hinge that holds the laptop computer in its 4 modes — clamshell, tent, media, and pill — and it’s fairly skinny at zero.58 inches and lightweight at 2.97 kilos. Evaluate that to the Spectre x360 at zero.67 inches and a pair of.88 kilos, and the Dell XPS 13 at zero.58 inches and a pair of.65 kilos. The Flex 5G took a little bit of a bounce in dimension over the Yoga C630, however that’s prone to account for the elevated battery capability — all the time a great factor in my guide.

Most necessary, the Flex 5G feels prefer it’s value its $1,500 funding, which is especially vital given that you just’re not getting one of the best configuration at this value. You received’t be left feeling such as you spent a lot cash on a laptop computer that simply isn’t constructed nicely sufficient.

Connectivity is comparatively restricted, with simply two USB-C three.2 ports on the left-hand facet and a three.5mm audio jack on the right-hand. There’s additionally a Nano SIM card slot and a change to bodily activate airplane mode. For such a futuristic gadget, we have been disenchanted to see Wi-Fi 5 and never Wi-Fi 6 to go along with Bluetooth 5.zero.

Keyboard and touchpad

The Flex 5G has the identical keyboard as just about each Yoga and Flex laptop computer on the market. It has vast keycaps with loads of spacing, and a quick mechanism with a tender bottoming motion. It is perhaps my creativeness, however the Flex 5G’s model appeared a bit shallower than some I’ve tried, and that’s not my favourite high quality. I like a little bit of journey in my keyboards. Total, although, I doubt many individuals will complain, and I used to be typing at just about full pace in a short time. To check with another glorious keyboards, the Flex 5G falls a bit behind the superb examples on the HP Spectre x360 13 and Dell XPS 13, to not point out the superior Magic Keyboard on the newest MacBooks.

The touchpad is of common dimensions for this dimension of a laptop computer, and it helps Microsoft’s Precision Touchpad protocol. Multitouch gestures and total cursor management was due to this fact glorious, and I had no complaints. The contact show was additionally responsive, though I’m certain some folks shall be very disenchanted that there’s no energetic pen assist. That’s just about a given with trendy 2-in-1s, and it’ll be missed right here.

Home windows 10 Howdy password-less assist is supplied in two methods. First, there’s an infrared digital camera offering facial recognition, and that labored in addition to on some other equally geared up machine. Second, there’s a fingerprint reader on the keyboard deck, and it, too, was quick and responsive. It’s good to have the choice.


My colorimeter received’t work with the Flex 5G for a scarcity of drivers, and so I couldn’t run the show by means of the standard battery of exams. I did give the show a great exercise and might present some subjective observations.

First, the show is brilliant, possible approaching Lenovo’s ranking of 400 nits. I wouldn’t say it competes with direct daylight, but it surely’s brilliant sufficient to make use of in most different ambient lighting.

Second, colours have been brilliant and appeared pure, and the show demonstrated loads of distinction. Black textual content on white backgrounds — my bread and butter — popped, and I by no means discovered myself pondering that textual content regarded washed out.

Lastly, I loved watching Netflix on the show, and so I’m guessing the gamma is shut to identify on. I can’t attest to how correct the colours are and whether or not it’s a great show for inventive sorts, however the typical productiveness employee and the house consumer ought to discover the show a pleasure.

The audio high quality was combined. Quantity was low, despite the 2 upward-firing audio system subsequent to the keyboard, however there was zero distortion. Bass was missing, not surprisingly, however mids and highs have been proper the place they need to be. Once more, it’s a great laptop computer for watching Netflix, though a set of headphones wouldn’t be a horrible concept.

Our take

The Lenovo Flex 5G isn’t the game-changer it needs to be, but it surely’s not solely responsible. 5G speeds and protection makes it laborious to justify a purchase order primarily based on connectivity alone. In the meantime, Home windows assist for ARM is an ongoing venture that Microsoft remains to be dragging its toes on.

These two applied sciences will possible play a giant position in the way forward for laptops. The Flex 5G’s unbelievable battery life is proof sufficient. However Qualcomm, Microsoft, and Verizon every have a whole lot of infrastructure to construct earlier than a laptop computer just like the Lenovo Flex 5G can really succeed by itself deserves.

Are there any options?

There aren’t some other 5G laptops presently available on the market, however they’re coming. And in the event that they assist greater than Verizon’s comparatively restricted 5G protection, they is perhaps higher choices from that perspective alone. So these are one thing to look out for.

When you don’t want 5G, then you would take into account the HP Spectre x360 13 with 4G LTE. You’ll spend about $150 much less and get a a lot sooner laptop computer, however you received’t get pleasure from practically the battery life. Assume in halves right here.

How lengthy will it final?

The Lenovo Flex 5G is a well-built laptop computer that ought to final for years, however its efficiency is simply going to get comparatively slower. In the meantime, 5G and Home windows on ARM expertise may see a wider roll-out within the coming years, and the Flex 5G ought to final lengthy sufficient to see the advantages.

The one-year guarantee is typical and disappointing.

Must you purchase it?

No — at the very least not but. Whereas battery life is stellar, efficiency is mediocre and barely retains up with primary productiveness and media consumption duties. That always-connected life-style shall be handy — however solely as soon as 5G sees a extra spectacular roll-out.
