Yet another 13-inch convertible! Dell Inspiron 13 7386 2-in-1 has arrived in our office, bearing Intel’s brand new Whiskey Lake (Coffelake refresh) CPUs and NVMe storage devices, everything about it sounds promising, but the competition is challenging. Lenovo Yoga 730, which we recently reviewed, is a strong contender, not to mention the classy Envy x360 by HP.
It also has to answer some questions. Like, is the Core i5-8265U a worthy refresh of the Core i5-8250U or it is just another marketing trick created to take the money out of people’s pockets. At first glance, the Inspiron 13 7386 2-in-1 has the looks but has it got the guts? Let’s find out!

Dell Inspiron 13 7386 2-in-1 technical specifications table
What’s in the box?
The packaging contains a compact 45W charger, some useless manuals and the laptop itself.
Design and construction
As we’ve said before, Dell Inspiron 13 7386 2-in-1 is very pretty. There is just something about it that makes it feel premium. When you touch it, when you lift it. The way it has a small footprint but also some heft to it. Enough superlatives. It is 13.7mm thick and weighs 1.4 kg. Yes, it is a little more than its competition, but in this case, it can never be too much. If you have read our full review of the Inspiron 14 5482 2-in-1 you know that, in our opinion, it is too heavy for a convertible. But keep in mind that this device is some 6mm thinner and 350 grams lighter than that.
The all aluminum body takes different shapes thanks to the hinges, which, in our opinion, are a little softer than they should be. There are some vibrations when you use the touchscreen in laptop mode. This touchscreen, however, is super responsive and supports Windows Ink and proprietory pens.
Moving down a little bit we find the other, more conservative, input devices. With a short travel and not very clicky feedback, the keyboard feels average. However, like its bigger cousin, it is illuminated. Just in front of the spacebar, you can see the touchpad. It feels okay – nothing special but it is more than fine for us. In the top right corner of the base is the fingerprint reader. It is probably the same sensor as in the Inspiron 14 5482 2-in-1, as it is exceptionally fast.
This device is equipped with bottom-firing speakers. It also breathes air from a relatively big vent on the bottom while hot air comes out of the device from its back.
|Dell Inspiron 13 7386 2-in-1||308 mm (12.09″)||212 mm (8.50″)||13.7 mm (0.55″)||1.40 kg (3.1 lbs)|
|Lenovo Yoga 730 (13)||307 mm (12.09″)||216 mm (8.50″)||13.9-14.1 mm (0.55″)||1.12 kg (2.5 lbs) (-20%)|
|HP Envy 13 x360||307 mm (12.09″)||215 mm (8.46″)||14.9 mm (0.59″) (+9%)||1.30 kg (2.9 lbs) (-7%)|
Dell has been pretty modest with the connectivity options of this device. We only have the power plug, an HDMI connector and a USB Type-C 3.1 (Gen. 1) with DisplayPort support on the left, and a regular USB 3.1 (Gen. 1) and a 3.5mm audio jack on the right. Sadly, no SD card reader nor Ethernet connection.
Disassembly, upgrade options and maintenance
Dell Inspiron 13 7386 2-in-1 is pretty easy to disassemble. Removing the 7 Phillips head screws result in a slight movement of the bottom plate. This movement allows you to easily stick a plastic pry tool inside, and pop the plate open.
As you can see, the heat pipe is a tad narrower than the one on its bigger brother. However it cools only a CPU here, so there should not be any problems in this aspect.
Moving our heads a little downwards reveals the sad truth of modern thin devices – soldered RAM chips. Make your choices carefully here because you can’t upgrade this one. However, this is at the expense of not one but two M.2 SSD slots! How cool is that for a 13-incher?!
Furthermore, at the bottom, we can see a long, but thin 38Wh battery unit. There was probably a little bit more room for battery here, but Dell played it safe, not pushing the boundaries too much.
In the last image, you can see how Dell has implemented the hinge mount on this laptop. It has four mounting points to the chassis and the arm is pretty long. This is definitely a strong connection here.
Our unit of Dell Inspiron 13 7386 2-in-1 is equipped with a Full HD IPS touchscreen panel, IVO M133NWF4 (IVO0536 / 8F4J5). Its diagonal is 13.3-inch (33.78 cm), and the resolution – 1920 х 1080p. Additionally, the screen ratio is 16:9, the pixel density – 166 ppi, their pitch – 0.153 х 0.153 mm. The screen can be considered Retina when viewed from at least 53 cm (from this distance, the average human eye can’t see the individual pixels).
Viewing angles are comfortable We offer images at different angles to evaluate the quality.
The maximum measured brightness is 210 nits (cd/m2) in the middle of the screen and 188 nits (cd/m2) average across the surface with a maximum deviation of 23% in the bottom right corner. This is unacceptably high value. The Correlated Color Temperature on a white screen and at maximum brightness is 5910K (average) – a little warmer than the 6500K temperature for sRGB, which is definitely not bad. The average color temperature through the grey scale before profiling is 5940K.
In the illustration below you can see how the display performs from uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 67% Brightness (White level = 143 cd/m2, Black level = 0.10 cd/m2).
Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color sensitive work (a maximum tolerance of 2.0 ). The contrast ratio is excellent – 1400:1 (1060:1 after profiling).
To make sure we are on the same page, we would like to give you a little introduction of the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.
Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people in HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.
Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.
The yellow dotted line shows Dell Inspiron 13 7386 2-in-1’s color gamut coverage.
Its display covers 51% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.
Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.
We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange etc. You can check out the results at factory condition and also, with the “Design and Gaming” profile.
Below you can compare the scores of Dell Inspiron 13 7386 2-in-1 with the default settings (left), and with the “Gaming and Web design” profile (right).
The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.
The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 27 ms.
Health impact – PWM / Blue Light
PWM (Screen flickering)
Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.
Dell Inspiron 13 7386 2-in-1 uses PWM to adjust its screen brightness for every level, except the maximum. While it does that with a relatively high frequency, it can still be harmful when exposed for a long period of time. However, you can eliminate that by installing our Health-Guard profile.
Blue light emissions
Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin and your whole body. You can find more information about that in our dedicated article on Blue Light.
You can see the levels of emitted blue light on the spectral power distribution (SPD) graph.
Having a super high contrast ratio and a Full HD resolution makes the screen of Dell Inspiron 13 7386 2-in-1 appear super crisp. However, it is also a bit dim for outdoor usage, which is definitely not helped by the glossy screen coating. In addition to that, it uses PWM-adjustment of its brightness, unless you are at the maximum level. A shortcoming is also the fact that you can see only half of the colors available on the Internet. However, if you would like to make them a little more accurate or want to eliminate the PWM you can get try our profiles.

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.
Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.
Design and Gaming
This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.
THealth-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.
Dell Inspiron 13 7386 2-in-1 is equipped with relatively good sounding speakers. While the highs are pretty clear, while the low and mid tones have some deviations.

Our configuration of Dell Inspiron 13 7386 2-in-1 came with an SK Hynix BC501 256GB NVMe drive. While it is behind the best SSDs on the market by much, it is still far better than many of the non-NVMe devices. Keep in mind that the choice of a storage device is strongly dependent on the region you live in.
|SSD model (480-512GB variants)||Max.Seq.Read (GB/s)||Max.Seq.Write (GB/s)||IOPS 4K Read||IOPS 4K Write||Latency Read (ms)||Latency Write (ms)|
|SK Hynix BC501 (NVMe)||1.44||0.81||9430||25397||0.044||0.035|
|Intel Pro 6000p Series||1.83||0.59||7792||28266||0.075||0.033|
Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. Obviously, as a 13-inch device, Inspiron 13 7386 doesn’t have a lot of space for a huge battery. Hence, the device has just 38Wh of juice.
This is the reason that the battery life of the laptop is average. We got around 7 hours of web browsing and 5 hours of video playback. Given that the Inspiron 13 7386 2-in-1 is definitely not a typical gaming device, you would be considered a Spartan if you decide to do some gaming, especially on battery power. However, it will all end after an hour and a half.
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
For every test like this, we use the same video in HD.
We use F1 2017’s built-in benchmark on loop in order to simulate real-life gaming.
The new Whiskey Lake processors have made their way to the Inspiron 13 7386 2-in-1 devices. Our unit was equipped with the Core i5-8256U which works on a base frequency of 1.60 GHz and a maximum Turbo one at 3.90 GHz.

Intel UHD Graphics 620 is a refresh of the HD Graphics 620 found as an integrated solution in many ULV Kaby Lake processors. UHD Graphics 620 is codenamed “Kaby Lake R U GT2” and it’s a part of the Gen 9.5 generation.
Intel UHD Graphics 620 has roughly the same performance as HD Graphics 620, depending on the other components in the system. UHD Graphics 620’s performance is similar to that of AMD Radeon R5 M420X and NVIDIA GeForce 910M/920M.

Temperatures and comfort
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.
Average core temperature (base frequency + X); CPU temp.
|Intel Core i5-8265U (15W TDP)||0:02 – 0:10 sec||0:15 – 0:30 sec||10:00 – 15:00 min|
|3.25 GHz @ 90°C||2.04 GHz @ 77°C||2.10 GHz @ 75°C|
As it is our first look at this processor we were pretty eager for this test. At first, we were very impressed by the 3.25 GHz the processor run at the beginning. However, shortly after the start, the frequencies plummeted down to 2.04 GHz, obviously because of reaching temperature thresholds. Thus, the temperature dropped from 90C on average for the first period, to 77C for the second. Interestingly, our measures at the end of the test showed even lower temperature – 75C and slightly higher clock speeds – 2.10 GHz. Sadly, this is still lower than what most devices with the “older” Core i5-8250U do.
When you look at the cooling system of this device you can easily draw conclusions about the end results of this test. Small heat pipe plus a tiny fan result in no good thermal efficiency. Moreover, we heard the processor screaming inside of the tight chassis… Well, at least that’s what we thought at the beginning, however it happened to be the coil whine, which is pretty frequent in this machine.
Dell has almost reached Lenovo the edge in the battle for 13-inch convertibles. This Inspiron is one of the devices that you feel a connection with. You know you are holding a premium product when it is in your hands. We can easily compare the Inspiron 13 7386 2-in-1 to its Latitude cousin – the 7390 2-in-1. At a cheaper price, you can feel the cost-cutting, but only when you boot up the device and dig a little deeper. However, in order to do things fair and square, there is another contender that should be brought in – the Lenovo Yoga 730 (13).
Performance-wise, the new Core i5-8265U fares pretty well against the i7-8550U, found in the Yoga 730. We can comfortably say that the difference is negligible. What was weird at this moment was that despite the Yoga 730 (13) features two fans and a larger heat pipe, its thermals showed arguably worse results in our temperature tests. However, the two devices were super responsive and didn’t stutter for a second so the battle will not be decided here.
If we took a look at the displays of these devices, however, the Dell Inspiron 13 7386 2-in-1 would lose. While both of them use PWM for brightness adjustment, the Inspiron can display just a fraction of the colors you can see on Yoga 730`s screen. In addition to that, the Yoga is far brighter as well. Thankfully, as its Lenovo counterpart, the Inspiron 13 7386 2-in-1`s touchscreen is on a very good level and is super responsive to both touch and pen.
Battery life here is reasonable – around 7 hours of browsing and 6 of video-enjoying. While this is not really impressive, there is something else about the Dell Inspiron 13 7386 2-in-1 that caught our eye – it has two M.2 SSD slots with NVMe support. Cool, huh?!
In conclusion, we can say that the Inspiron 13 7386 2-in-1 is a very well built aluminum device that has a premium taste and very responsive hardware and software. We can definitely recommend this product, but you can still check out the Lenovo Yoga 730 (13) since it can offer quite the same experience as the Inspiron.
