Dell Latitude 15 5511 review – good battery life and potent CPUs for your business

Today, we are going to look at pretty much a copy of the Latitude 15 5510 from yesterday. Ultimately, it is the same business notebook from the outside, with the same security enhancements and system optimizations, but with a lot more powerful CPU inside the chassis.

Instead of the low-power 15W Comet Lake processors, the Latitude 15 5511 comes with the “H” version of the same family of devices. However, to keep the heat down (or more probably for better battery life), Dell puts a 35W power limit on all of the H-series CPUs. We’ll see how this copes with other notebooks featuring the same processors, but before we get there, let’s take a quick look at the design, and what’s inside the box.

What’s in the box?

This laptop comes with a 90W power brick, as well as some paper manuals, inside the box.


Design and construction

As we expected, the Latitude 15 5511 is slightly thicker and marginally heavier than its ULV brother – the Latitude 15 5510 – 22.4mm thickness in the front, and 24.9mm in the back, while the weight is 1.89 kg. Other than that, the materials in use are pretty much the same – including plastic, carbon fiber, and aluminum. By the way, once again, the carbon fiber here is partially recycled, which is great for the environment.

Again, you won’t be able to open the lid with a single hand. On the bright side, the lid is pretty strong (as is the body by the way). Furthermore, there is an HD camera with a privacy shutter.

Keyboard-wise, we got a great unit with a long travel, clicky feedback, and a feature-packed NumberPad section. And even though the keycaps are a bit smaller, the overall comfort is great. Not on the last place, there is a dedicated Nipple, which as its own buttons right below the Space key. As of the touchpad, its a bit average, but this doesn’t mean it doesn’t provide a comfortable experience.

Lastly, if we look at the bottom panel we can see that the ventilation grills are a bit smaller in area than those on the Latitude 15 5510. Other than that – the speakers have the same location, and the exhaust is placed on the left side, as well.

Ports

On the left side, we got the Power plug, a Thunderbolt 3 port, a USB Type-A 3.2 (Gen. 1) port, and here you will also find the optional Smart card reader. And on the right, you can see an RJ-45 connector, an HDMI 2.0 connector, two USB Type-A 3.2 (Gen. 1) ports, an audio jack, a MicroSD card slot, and a micro-SIM card slot.


Disassembly, upgrade options and maintenance

This notebook has a total of 8 Phillips-head screws that hold the bottom panel. After you undo them, you just need to pop the plastic clips with a plastic pry tool, and you should be able to effortlessly lift the panel away.

Thankfully, we see two significantly thicker heat pipes, when compared to the Latitude 15 5510. Also, the fan seems to be a bit larger as well.

Moreover, this machine can employ up to 64GB of DDR4 memory in dual channel, and it’s all user-replaceable. And in terms of storage, there is a single M.2 PCIe x4 slot, as well as a 2.5-inch SATA drive bay.

Not on the last place, depending on the configuration, you’ll get one of three different batteries. A 51Wh one, a 68Wh one, or a monstrous 97Wh unit.


Display quality

Dell Latitude 15 5511 has a Full HD IPS panel with a model number BOE NV156FHM-N4H (BOE0869). Its diagonal is 15.6″ (39.62 cm), and the resolution 1920 х 1080 pixels. The screen ratio is 16:9, and we are looking at a pixel density of – 142 ppi, and a pitch of 0.18 х 0.18 mm. The screen turns into Retina when viewed at distance equal to or greater than 60cm (24″) (from this distance one’s eye stops differentiating the separate pixels, and it is normal for looking at a laptop).

Viewing angles are comfortable. We offer images at 45° to evaluate image quality.

The measured maximum brightness of 242 nits in the middle of the screen and 227 nits as an average for the whole area, with a maximum deviation of 8%. The Correlated Color Temperature on a white screen is 6370K – slightly warmer than the sRGB standard of 6500K, which is great.
In the illustration below you can see how the display performs from a uniformity perspective. In other words, the leakage of light from the light source.

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. The contrast ratio is decent – 1160:1.

To make sure we are on the same page, we would like to give you a little introduction to 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 Latitude 15 5511’s color gamut coverage.

Its display covers 50% 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 Latitude 15 5511 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 = 29 ms


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 Latitude 15 5511’s display uses PWM to adjust its brightness at all levels. Additionally, the flickerings have a 1000 Hz frequency, which is slightly uncomfortable for long work periods.

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.

Conclusion

Dell Latitude 15 5511 has an IPS panel with a Full HD resolution, comfortable viewing angles, good contrast ratio, and somewhat adequate default settings. Sadly, it covers only 50% of sRGB, and its backlight does flicker at all brightness levels, except for the maximum (our Health-Guard profile fixes the issue).

Well, you can clearly see, that the efficiency of this cooling system isn’t great. Although two heat pipes of this size should be more than capable to handle this CPU’s 35W L2 power limit, the single fan just can’t cope.

Comfort during full load

We found the notebook a bit louder than what we would like, and the hottest spot on the keyboard was just shy of 50C.


Verdict

So, guys, if we have to be honest, the laptop we’ve reviewed today is 99% the same piece of machinery, as the Latitude 15 5510. It has pretty much the same body (although it is a bit thicker and heavier), and the features are basically the same. Ultimately, this means that the only meaningful difference between the two is the performance. And with the quad-core CPUs, we clearly got a significant victory for the H-series devices. And we expect the difference to be even greater when you jump to the 6-core unites.

Another win for the Latitude 15 5511 is the ability to put both an M.2 PCIe x4 drive and a 2.5″ SATA device simultaneously – something that was forbidden by the law of physics with its brother. In addition to that, you get an optional Wi-Fi 6 certification, Thunderbolt 3, MicroSD card reader, and LTE support.

Similarly to its brother – Latitude 15 5510, Dell Latitude 15 5511 has an IPS panel with a Full HD resolution, comfortable viewing angles, good contrast ratio, and somewhat adequate default settings. Sadly, it covers only 50% of sRGB, and its backlight does flicker at all brightness levels, except for the maximum (our Health-Guard profile fixes the issue).

As you can see, in most areas, today’s notebook is outperforming its ULV sibling. However, there is the battery life, where the latter takes the win. If you remember, we got 15 hours and a half of Web browsing from the other notebook, and today’s machine got us through “only” 12 hours and 9 minutes. Don’t get us wrong, this is still a great result, but it’s just not as high as that of the Latitude 15 5510.

Ultimately, if you don’t need so much CPU power, we would advise going for the Comet Lake-U device, as it’s going to be significantly cheaper. Also, the cooling of the Latitude 15 5511 doesn’t let you extract everything from its processors, even though they are running at a lower 35W TDP.

Pros

  • Strong body
  • One of the best keyboards on a laptop
  • I/O and upgradability are on point
  • Great battery life
  • Optional fingerprint reader
  • Great viewing angles and contrast ratio (BOE NV156FHM-N4H (BOE0869))
  • Optional Thunderbolt support and PCIe x4 M.2 slot
  • Environmentally-conscious with up to 18% of recycled Carbon fiber


Cons

  • A bit pricey
  • Runs a bit too hot under heavy load
  • Covers only 50% of sRGB (BOE NV156FHM-N4H (BOE0869))
  • Uses PWM to adjust its brightness (fixed by our Health-Guard profile) (BOE NV156FHM-N4H (BOE0869))

When Intel upgrades this laptop with Tiger Lake, it will become a great laptop:
+ PCIe 4.0
+ 11th gen CPU, probably 35W only and Iris Xe HP/Max Graphics
+ 2 x Thunderbolt 4, USB 3.2 (20 Gbps)
+ VP9 encoding, AV1 decoding
They should DEFINITELY add a second fan and remove the place for extra 2.5 inch SATA SSD, replace it with another slot for an M.2 SATA/NVMe SSD

I have 5511 at work. Thermal performance is NOT ACCEPTABLE!. It goes 100 C degrees even without heavy load. And often mouse starts to jump over the screen like in old 486. Cooling in this laptop is a joke. Laud and not doing its job. I get 100C on CPU even if this laptop lays on zalman cooling pad.
