Lenovo Flex 5 Review

December 7, 2018

Lenovo has updated the 15-inch Flex 5 with eighth-generation Intel processors. A similarly configured version to the one particular reviewed here is offered with lenovo x1 carbon 20bt battery new processor choices.

Lenovo’s Yoga two-in-one laptop line is so varied in sizes and configurations that it can be quite tough to nail down the differences involving them. To additional confuse points, the Yoga 520 is called the Flex five inside 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 out there inside the US.

The 15.6-inch Flex five begins about $600 and goes up to $1,110 (that is about £780 or AU$1,430). The configuration I reviewed is usually a sweet spot inside the line, delivering a very good balance of functionality, options and lenovo thinkpad yoga s1 battery replacement/lenovo thinkpad yoga 20cd battery battery life. Lenovo tends to make a 14-inch Flex 5, too, that is alternatively named the Yoga 520 for the UK and Australia, but none of them may be configured fairly the same because the 15.6-inch Flex 5.

The larger 15.6-inch screen size tends to make it a very good choice for all those who want to have a single laptop or computer for operate and lenovo yoga 900 13isk2 battery/yoga 900 13isk battery entertainment, although still getting portable sufficient for throwing in a backpack or briefcase. Plus, the bigger two-in-one style is terrific for watching movies or providing presentations, and this system’s discrete graphics even enable some low-level gaming. That mentioned, in the event you are going to do loads of traveling or require something to get a day-to-day transit commute, you could need to go with something smaller sized and lighter like the 13.3-inch Yoga 720. (The 720 also comes within a 15.6-inch size, but additional on that later.)

Design

The Flex five convinced me that small design and style tweaks make all the distinction. 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 appear you do not see that typically.

At four.7 pounds and 0.eight inches thick, the Flex 5 1570 is equivalent in heft and size towards the surface pro 4 charger/microsoft surface pro 4 charger bend-back Lenovo Yoga 720 (four.6 pounds, 0.eight inches) and also the Dell XPS 15 (four.6 pounds, 0.7 inches), that is not a 2-in-1. The Samsung Notebook 9 Pro (three.eight pounds, 0.7 inches thick) and HP Spectre x360 (four.four pounds, 0.7 inches) — each convertibles — are lighter.

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

The Flex 5 provides a fairly regular set of ports. Around the left, you are going to obtain the machine’s power jack, HDMI output, a USB three.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, security lock slot and SD memory reader on the ideal, and its fingerprint reader sits below the bottom suitable corner from the keyboard. If only that Type-C port charged or supported Thunderbolt three, the Flex 5 could be extra future-proof.

Keyboard

The keyboard (27.8 x 10.five cm) is primarily identical to what the Ideapad series has to present. Users who’ve typed on 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 somewhat quiet with a low-medium level of feedback. The Enter crucial and smaller major row of Function keys could have benefited from becoming firmer.

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

Touchpad

The Precision trackpad (ten.five x 7.0 cm) is smaller sized than the trackpads on the XPS 15 (10.five x 8.five cm) and toshiba battery pa3817u 1brs/toshiba laptop battery pa3817u 1brs Zenbook Flip 15 (ten.five x 7.three cm). Thankfully, glide is still smooth and responsive devoid of any issues. The integrated click keys are a bit soft and could happen to be firmer. Additionally they tend to stick and so speedy clicks are much more tough to perform than they need to be.

Display

The fantastic 15.6-inch display in the Flex five delivers bright, colorful, hi-res picture high-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 created the 4K film’s finer particulars, which include the tiny type in floating holographic text, appear super clear.

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

Emitting as much as 270 nits of brightness, the Flex 5’s show is stronger than the 258-nit category average plus the 255-nit panel in the Spectre x360, and equivalent to the displays inside the dell 40wh m5y1k battery/dell m5y1k battery Yoga 720, XPS 15 and Notebook 9 Pro (266 to 282 nits). While the panel’s colors stayed robust at up to 75 degrees for the left and suitable, 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.

Performance

Current SKUs on the Flex 5 15 might be configured together with the Core i5-8250U or i7-8550U CPU and either UHD Graphics 620 or GeForce MX130 graphics. Exactly the same FHD IPS touchscreen comes typical across all configurations. It’s clear that Lenovo is advertising and marketing the technique as dell inspiron 15 7559 charger/dell inspiron 7559 charger an inexpensive option for the well-known Dell XPS 15 or HP Spectre x360 15 based on the specifications alone. Sadly, no Ryzen options are offered which would have match completely within the TDP envelope from the Flex five.

Processor

CPU functionality is poor when in comparison with other systems equipped with lenovo yoga 700 14isk charger/lenovo yoga 700 14isk battery the identical i7-8550U CPU. The Flex 5 is able to score just 388 points in CineBench R15 Multi-Thread whereas the typical Core i7-8550U in our database scores about 571 points. This huge delta is further explored in our Stress Test section under, however it primarily boils down to poor Turbo Increase functionality from the Lenovo convertible. Its CPU is just not able to sustain Turbo Increase clock rates for even quick periods and so efficiency suffers consequently. Final scores are disappointing to say the least when even the Core i5-8250U within the Ideapad 530S is able to outperform the i7-8550U in our Flex 5 by 26 %.

Running CineBench R15 Multi-Thread in a loop shows us just how poor the Flex five is usually at sustaining Turbo Enhance. Its initial score of 541 points tanks to just 385 points just after only two or toshiba laptop battery pa5109u 1brs/toshiba battery pa5109u 1brs three loops to represent a functionality drop of 29 %. Our program under no circumstances recovers thereafter until the loop test is stopped.

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

Energy Management

Power Consumption

Idling on desktop demands anyplace amongst 4 W to 8 W according to 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.eight cm) 65 W AC adapter. The Huawei MateBook D draws about 9 W more with its slightly more quickly GeForce MX150 graphics when under high loads.

Monitoring energy consumption over time when operating Prime95 shows exciting results. Consumption spikes to as higher 45 W at the quite start off on the test prior to straight away 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 proper. This reflects our CineBench loop test above where Turbo Enhance sustainability was shown to become really poor.

Battery Life

The internal 52.five Wh battery is larger than what you’d locate around the Pavilion x360 15 and lenovo yoga 2 13 model 20344 charger concerning the identical as on the much more highly effective 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 in the lowest settings and brightness can final for pretty much 19 hours prior to shutdown. The program cheats a little, nonetheless, as its lowest brightness setting turns off the backlight and lenovo x1 carbon 20bt battery/lenovo x1 carbon battery 20bs show totally to save on energy. For most other notebooks, the display continues to be visible even though on the lowest brightness setting. Getting anyplace near 19 hours is just about not possible on the Flex five through real-world scenarios.

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

Verdict

The Flex five is not for enthusiasts or efficiency customers and Lenovo knows this. Rather, the spending budget system is for the residence multimedia user or student who may possibly basically want an economical 15-inch Windows laptop with lenovo ideapad p400 touch battery/lenovo p400 touch battery tablet functions for movie playback, word processing, and the occasional casual games. It presents no considerable benefits more than the Pavilion 2-in-1, Vivobook 2-in-1, Envy 2-in-1, or heavier Inspiron 15 2-in-1 besides an selection for the slow GeForce MX130 GPU. As an at-home loved ones convertible, the Flex 5 fits the bill just barely.

There is really a lengthy list of unfortunate overall performance cutbacks. The extremely dim display means this can be a convertible mostly for indoor use plus the exceptionally restricted Turbo Increase signifies there’s very little explanation to purchase the Core i7-8550U SKU when the much less high priced i5-8250U SKU can perform nearly the same. Its single-channel RAM hampers overall performance even additional and Battery Toshiba P000614130 52Wh the cooling resolution is embarrassingly tiny given the roomy 15-inch kind issue. There is ample empty space surrounding the fan that could have been utilized for a larger cooling remedy to cut down fan noise.
