Lenovo Flex 5 Review

Lenovo has updated the 15-inch Flex five with eighth-generation Intel processors. A similarly configured version towards the one particular reviewed here is offered with lenovo x1 carbon 20bt battery new processor selections.

Lenovo’s Yoga two-in-one laptop line is so varied in sizes and configurations that it may be really tough to nail down the variations between them. To further confuse points, the Yoga 520 is known as the Flex five within the US and acer swift 7 battery/acer swift 7 sf713 battery it comes in two sizes, one of which — the 15.6-inch model reviewed right here — is only offered in the US.

The 15.6-inch Flex 5 starts about $600 and goes as much as $1,110 (that’s about £780 or AU$1,430). The configuration I reviewed can be a sweet spot in the line, delivering an excellent balance of overall performance, capabilities and lenovo thinkpad yoga s1 battery replacement/lenovo thinkpad yoga 20cd battery battery life. Lenovo makes a 14-inch Flex five, as well, that is alternatively named the Yoga 520 for the UK and Australia, but none of them may be configured rather the identical because the 15.6-inch Flex five.

The larger 15.6-inch screen size tends to make it a great selection for all those who wish to have 1 laptop or computer for work and lenovo yoga 900 13isk2 battery/yoga 900 13isk battery entertainment, while nonetheless being transportable enough for throwing inside a backpack or briefcase. Plus, the bigger two-in-one style is wonderful for watching motion pictures or giving presentations, and this system’s discrete graphics even allow some low-level gaming. That stated, if you are going to perform a lot of traveling or have to have some thing for any every day transit commute, you could would like to go with some thing smaller and lighter like the 13.3-inch Yoga 720. (The 720 also comes within a 15.6-inch size, but more on that later.)


The Flex 5 convinced me that little design tweaks make all the difference. The Onyx Black lid sports an aluminum finish that catches the light, which bounces off the machine’s shiny, razor-thin, bevelled edges. The dark-gray deck and underside give this 2-in-1 a classy two-tone look you don’t see that typically.

At four.7 pounds and 0.8 inches thick, the Flex 5 1570 is similar in heft and size to the surface pro 4 charger/microsoft surface pro 4 charger bend-back Lenovo Yoga 720 (4.six pounds, 0.eight inches) and also the Dell XPS 15 (4.6 pounds, 0.7 inches), which is not a 2-in-1. The Samsung Notebook 9 Pro (three.eight pounds, 0.7 inches thick) and HP Spectre x360 (4.4 pounds, 0.7 inches) — both convertibles — are lighter.

The Flex’s 360-degree hinges are lots sturdy, as I saw the Flex five remain in place in each tent and show modes. I did notice a slight wobble when tapping on the screen in stand or laptop modes.

The Flex 5 offers a fairly normal set of ports. Around the left, you are going to come across the machine’s power jack, HDMI output, a USB 3.0 port, a (data-only) USB Type-C port and dell inspiron 15 7559 charger/dell inspiron 7559 charger the headphone jack. Lenovo placed the second USB three.0 port, safety lock slot and SD memory reader on the proper, and its fingerprint reader sits under the bottom proper corner of your keyboard. If only that Type-C port charged or supported Thunderbolt three, the Flex five will be additional future-proof.


The keyboard (27.eight x ten.five cm) is primarily identical to what the Ideapad series has to give. Users who’ve typed on the Ideapad 530S or 720S will know what to expect from pa5121u 1brs/toshiba battery pa5121u 1brs the Flex 5 15. The flat keys are shallow and somewhat quiet using a low-medium amount of feedback. The Enter essential and compact prime row of Function keys could have benefited from getting firmer.

A two-level white backlight is included across all SKUs.


The Precision trackpad (10.five x 7.0 cm) is smaller sized than the trackpads around the XPS 15 (ten.five x 8.five cm) and toshiba battery pa3817u 1brs/toshiba laptop battery pa3817u 1brs Zenbook Flip 15 (10.five x 7.three cm). Fortunately, glide continues to be smooth and responsive with no any concerns. The integrated click keys are a little soft and could happen to be firmer. In addition they have a tendency to stick and so speedy clicks are much more difficult to perform than they must be.


The superb 15.6-inch show in the Flex 5 provides vibrant, colorful, hi-res picture good quality. As I watched the sci-fi film Tears of Steel around the machine, the movie’s vivid purple lasers, inky-black shadows and lenovo think pad x1 carbon 20fb battery vibrant green ferns impressed me. The 3840 x 2160-pixel panel made the 4K film’s finer details, which include the tiny variety in floating holographic text, seem super clear.

According to our colorimeter, the Flex five produces 133 percent of the sRGB spectrum. That is additional than the asus ux32vd battery/asus zenbook ux32vd battery 99-percent mainstream notebook average and also the readings from the Spectre x360 (113 %), Yoga 720 (114 percent) and Notebook 9 Pro (107 percent). The XPS 15 developed an even-higher 188 percent.

Emitting as much as 270 nits of brightness, the Flex 5’s display is stronger than the 258-nit category average along with the 255-nit panel inside the Spectre x360, and equivalent to the displays in the dell 40wh m5y1k battery/dell m5y1k battery Yoga 720, XPS 15 and Notebook 9 Pro (266 to 282 nits). Whilst the panel’s colors stayed sturdy at up to 75 degrees for the left and appropriate, the reflection of our office lighting clouded the pane.

The Flex 5’s touchscreen accurately tracked my touch input and properly registered swipe-in gestures. Although I saw no latency when doodling in MS Paint, drawing in Fresh Paint or lenovo thinkpad x1 yoga charger navigating the net inside the Edge browser, I did notice some slowness in Paint 3D.


Current SKUs from the Flex 5 15 may be configured using the Core i5-8250U or i7-8550U CPU and either UHD Graphics 620 or GeForce MX130 graphics. Exactly the same FHD IPS touchscreen comes normal across all configurations. It’s clear that Lenovo is marketing and advertising the technique as dell inspiron 15 7559 charger/dell inspiron 7559 charger an economical alternative towards the common Dell XPS 15 or HP Spectre x360 15 based on the specifications alone. Sadly, no Ryzen alternatives are out there which would have fit completely within the TDP envelope with the Flex five.


CPU overall performance is poor when in comparison with other systems equipped with lenovo yoga 700 14isk charger/lenovo yoga 700 14isk battery precisely the same i7-8550U CPU. The Flex 5 is capable to score just 388 points in CineBench R15 Multi-Thread whereas the average Core i7-8550U in our database scores about 571 points. This enormous delta is further explored in our Strain Test section beneath, but it primarily boils down to poor Turbo Boost functionality in the Lenovo convertible. Its CPU is merely not in a position to sustain Turbo Enhance clock rates for even short periods and so efficiency suffers consequently. Final scores are disappointing to say the least when even the Core i5-8250U inside the Ideapad 530S is able to outperform the i7-8550U in our Flex five by 26 %.

Running CineBench R15 Multi-Thread inside a loop shows us just how bad the Flex five might be at sustaining Turbo Boost. Its initial score of 541 points tanks to just 385 points immediately after only two or toshiba laptop battery pa5109u 1brs/toshiba battery pa5109u 1brs three loops to represent a performance drop of 29 %. Our method in no way recovers thereafter until the loop test is stopped.

Energy Management

Power Consumption

Idling on desktop demands anyplace involving four W to eight W according to the brightness setting and energy profile. Maximum load draws about 43 W more than a 90-second period from lenovo yoga 3 14 battery/lenovo yoga 3 14 battery replacement the little (~7.five x 7.5 x two.eight cm) 65 W AC adapter. The Huawei MateBook D draws about 9 W extra with its slightly faster GeForce MX150 graphics when below higher loads.

Monitoring power consumption over time though running Prime95 shows exciting results. Consumption spikes to as high 45 W in the incredibly get started of the test just before quickly falling and hp spectre x360 13 battery/hp spectre x360 13 4066nz battery stabilizing at 23.7 W as shown by the image around the ideal. This reflects our CineBench loop test above where Turbo Boost sustainability was shown to become pretty poor.

Battery Life

The internal 52.five Wh battery is larger than what you’d find on the Pavilion x360 15 and lenovo yoga 2 13 model 20344 charger concerning the same as on the far more strong Asus ZenBook Flip 15. Runtime for the duration of WLAN load is respectable at 7.5 hours to become comparable to other 15-inch multimedia systems.

Idling on desktop at the lowest settings and brightness can final for just about 19 hours just before shutdown. The method cheats a little, even so, as its lowest brightness setting turns off the backlight and lenovo x1 carbon 20bt battery/lenovo x1 carbon battery 20bs display completely to save on energy. For many other notebooks, the display continues to be visible even when around the lowest brightness setting. Receiving anyplace close to 19 hours is pretty much not possible on the Flex five during real-world scenarios.

Charging from close to empty to complete capacity takes about 2 hours.


The Flex 5 isn’t for enthusiasts or performance users and Lenovo knows this. Alternatively, the price range method is for the dwelling multimedia user or student who may perhaps merely want an cheap 15-inch Windows laptop with lenovo ideapad p400 touch battery/lenovo p400 touch battery tablet features for film playback, word processing, as well as the occasional casual games. It provides no substantial benefits more than the Pavilion 2-in-1, Vivobook 2-in-1, Envy 2-in-1, or heavier Inspiron 15 2-in-1 aside from an selection for the slow GeForce MX130 GPU. As an at-home loved ones convertible, the Flex five fits the bill just barely.

There is a long list of unfortunate functionality cutbacks. The pretty dim display suggests this can be a convertible mostly for indoor use and also the really limited Turbo Boost suggests there is really tiny purpose to purchase the Core i7-8550U SKU when the much less high priced i5-8250U SKU can perform almost exactly the same. Its single-channel RAM hampers overall performance even additional and Battery Toshiba P000614130 52Wh the cooling remedy is embarrassingly modest offered the roomy 15-inch form issue. There’s ample empty space surrounding the fan that could happen to be utilized for a bigger cooling solution to cut down fan noise.
