Lenovo Flex 5 Review

Lenovo has updated the 15-inch Flex 5 with eighth-generation Intel processors. A similarly configured version towards the one reviewed here is accessible 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 extremely tough to nail down the differences involving them. To additional confuse issues, the Yoga 520 is known as the Flex five in the US and acer swift 7 battery/acer swift 7 sf713 battery it comes in two sizes, certainly one of which — the 15.6-inch model reviewed right here — is only accessible inside the US.

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

The bigger 15.6-inch screen size makes it a great decision for all those who desire to have a single computer for operate and lenovo yoga 900 13isk2 battery/yoga 900 13isk battery entertainment, though nevertheless getting portable sufficient for throwing in a backpack or briefcase. Plus, the larger two-in-one style is terrific for watching motion pictures or giving presentations, and this system’s discrete graphics even let some low-level gaming. That stated, in the event you are going to accomplish a great deal of traveling or have to have something for any every day transit commute, you could choose to go with something smaller sized and lighter like the 13.3-inch Yoga 720. (The 720 also comes inside a 15.6-inch size, but additional on that later.)


The Flex five convinced me that little design and style tweaks make each of 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 do not see that frequently.

At 4.7 pounds and 0.8 inches thick, the Flex five 1570 is related in heft and size for the surface pro 4 charger/microsoft surface pro 4 charger bend-back Lenovo Yoga 720 (four.6 pounds, 0.8 inches) as well as the Dell XPS 15 (4.six pounds, 0.7 inches), which can be not a 2-in-1. The Samsung Notebook 9 Pro (3.8 pounds, 0.7 inches thick) and HP Spectre x360 (four.four pounds, 0.7 inches) — both convertibles — are lighter.

The Flex’s 360-degree hinges are a lot sturdy, as I saw the Flex 5 keep in spot in each tent and display modes. I did notice a slight wobble when tapping around the screen in stand or laptop modes.

The Flex five presents a pretty regular set of ports. On the left, you will discover the machine’s energy 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 3.0 port, safety lock slot and SD memory reader on the ideal, and its fingerprint reader sits under the bottom appropriate corner on the keyboard. If only that Type-C port charged or supported Thunderbolt three, the Flex 5 would be extra future-proof.


The keyboard (27.eight x ten.five cm) is essentially identical to what the Ideapad series has to offer. Users that have typed around the Ideapad 530S or 720S will know what to anticipate from pa5121u 1brs/toshiba battery pa5121u 1brs the Flex 5 15. The flat keys are shallow and reasonably quiet using a low-medium degree of feedback. The Enter key and modest top row of Function keys could have benefited from being firmer.

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


The Precision trackpad (ten.five x 7.0 cm) is smaller sized than the trackpads around the XPS 15 (ten.five x 8.5 cm) and toshiba battery pa3817u 1brs/toshiba laptop battery pa3817u 1brs Zenbook Flip 15 (10.5 x 7.3 cm). Thankfully, glide is still smooth and responsive without any difficulties. The integrated click keys are a bit soft and could happen to be firmer. They also tend to stick and so fast clicks are a lot more hard to execute than they must be.


The fantastic 15.6-inch display in the Flex 5 presents vibrant, colorful, hi-res picture top quality. As I watched the sci-fi film Tears of Steel on 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 facts, for example the tiny type in floating holographic text, appear super clear.

According to our colorimeter, the Flex five produces 133 % in the sRGB spectrum. That’s extra than the asus ux32vd battery/asus zenbook ux32vd battery 99-percent mainstream notebook typical as well as the readings in the Spectre x360 (113 %), Yoga 720 (114 %) and Notebook 9 Pro (107 percent). The XPS 15 developed an even-higher 188 percent.

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

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


Current SKUs from the Flex five 15 is usually configured with the Core i5-8250U or i7-8550U CPU and either UHD Graphics 620 or GeForce MX130 graphics. Precisely the same FHD IPS touchscreen comes standard across all configurations. It’s clear that Lenovo is promoting the system as dell inspiron 15 7559 charger/dell inspiron 7559 charger an inexpensive option towards the well-liked Dell XPS 15 or HP Spectre x360 15 based on the specifications alone. Sadly, no Ryzen options are readily available which would have match perfectly within the TDP envelope from the Flex five.


CPU functionality is poor when compared to other systems equipped with lenovo yoga 700 14isk charger/lenovo yoga 700 14isk battery the exact same i7-8550U CPU. The Flex five is in a position to score just 388 points in CineBench R15 Multi-Thread whereas the typical Core i7-8550U in our database scores about 571 points. This massive delta is additional explored in our Strain Test section under, but it primarily boils down to poor Turbo Increase overall performance from the Lenovo convertible. Its CPU is merely not able to keep Turbo Increase clock prices for even short periods and so overall performance suffers because of this. Final scores are disappointing to say the least when even the Core i5-8250U within the Ideapad 530S is in a position to outperform the i7-8550U in our Flex five by 26 %.

Running CineBench R15 Multi-Thread in a loop shows us just how terrible the Flex five could be at sustaining Turbo Increase. 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 3 loops to represent a efficiency drop of 29 %. Our method under no circumstances recovers thereafter until the loop test is stopped.

See our dedicated web page on the Core i7-8550U for more technical information and benchmark comparisons.

Energy Management

Power Consumption

Idling on desktop demands anywhere amongst four W to 8 W based on the brightness setting and power profile. Maximum load draws about 43 W over a 90-second period from lenovo yoga 3 14 battery/lenovo yoga 3 14 battery replacement the modest (~7.five x 7.five x two.8 cm) 65 W AC adapter. The Huawei MateBook D draws about 9 W a lot more with its slightly quicker GeForce MX150 graphics when beneath higher loads.

Monitoring power consumption over time although operating Prime95 shows interesting final results. Consumption spikes to as high 45 W in the quite start out of your test before promptly 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 suitable. This reflects our CineBench loop test above where Turbo Enhance sustainability was shown to be very poor.

Battery Life

The internal 52.five Wh battery is larger than what you’d uncover on the Pavilion x360 15 and lenovo yoga 2 13 model 20344 charger about the same as on the extra potent Asus ZenBook Flip 15. Runtime through 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 pretty much 19 hours just before shutdown. The method cheats a bit, having said that, as its lowest brightness setting turns off the backlight and lenovo x1 carbon 20bt battery/lenovo x1 carbon battery 20bs show completely to save on power. For most other notebooks, the show continues to be visible even when around the lowest brightness setting. Having anyplace close to 19 hours is pretty much not possible on the Flex five for the duration of real-world scenarios.

Charging from near empty to complete capacity requires about two hours.


The Flex 5 is just not for enthusiasts or performance customers and Lenovo knows this. As an alternative, the spending budget program is for the residence multimedia user or student who may simply want an inexpensive 15-inch Windows laptop with lenovo ideapad p400 touch battery/lenovo p400 touch battery tablet attributes for film playback, word processing, along with the occasional casual games. It provides no significant positive aspects over the Pavilion 2-in-1, Vivobook 2-in-1, Envy 2-in-1, or heavier Inspiron 15 2-in-1 apart from an alternative for the slow GeForce MX130 GPU. As an at-home family members convertible, the Flex five fits the bill just barely.

There is actually a lengthy list of unfortunate performance cutbacks. The pretty dim display suggests this is a convertible primarily for indoor use as well as the really limited Turbo Boost indicates there is certainly really tiny reason to purchase the Core i7-8550U SKU when the less high priced i5-8250U SKU can execute practically the exact same. Its single-channel RAM hampers functionality even additional and Battery Toshiba P000614130 52Wh the cooling resolution is embarrassingly modest offered the roomy 15-inch kind aspect. There is ample empty space surrounding the fan that could have already been utilized for any bigger cooling remedy to decrease fan noise.
