2021 Dell Latitude 5520 : Our In-Depth Review!

Dell Latitude 5520 : Performance + Verdict!


Dell Latitude 5520 : Performance

Our Dell Latitude 5520 is powered by the 28 watt Intel Core i7-1185G7 processor, with 4 cores and 8 threads, and Iris Xe Graphics with 96 Execution Units.

This processor has 12 MB of L3 cache, a 3.0 GHz base frequency that ramps up to 4.8 GHz during intensive tasks.

Our review sample came with 16 GB of DDR4-3200 memory – in dual memory channels, of course, and a 512 GB Western Digital SN730 SSD.

Work Performance : PCMark 10

The Intel Core i7-1185G7 is a 28 watt processor that can be configured to run at a lower TDP of 12 watt – to improve battery life and reduce thermal output.

Dell left it at the full 28 watt TDP for maximum performance, so it delivered PCMark 10 scores in excess of 4800.

This makes the Dell Latitude 5520 about 15% faster than the HUAWEI MateBook X Pro, which uses the Intel Core i7-10510U 25W processor, and 25% faster than the XPS 13, which uses a down-clocked Intel Core i7-1065G7 processor at 15 W.

Gaming Performance : 3DMark Time Spy

The Dell Latitude 5520 is not meant to be a gaming system, but it has surprisingly decent gaming chops.

The Intel Core i7-1185G7 comes with integrated Iris Xe Graphics, with 96 execution units and maximum clock speed of 1.35 GHz.

That gave it a 3DMark Time Spy score just shy of 1190. That makes it about as fast as the NVIDIA GeForce MX350, and a little faster than the Radeon RX Vega 5 integrated graphics used in Ryzen 4000 Mobile processors.

Battery Life : YouTube + Modern Office

Our Dell Latitude 5520 came with a 4-cell lithium-ion battery, that has a rated capacity of 63 Whr.

To test its battery life, we locked the brightness at 50% – higher than the average of 40% – to see how it performs in these worst-case scenarios :

YouTube Streaming

The Dell Latitude 5520 lasted 8 hours 18 minutes streaming YouTube videos in the theatre mode using Wi-Fi, before its battery dropped to 10%.

PCMark 10 : Modern Office

The Dell Latitude 5520 lasted a phenomenal 11 hours before it powered off while running the Modern Office benchmark!

Battery Recharging Speed

Its 45 watt compact fast charger supports ExpressCharge Boost, which lets it deliver up to 35% charge in about 20 minutes, or up to 80% charge in an hour.

In our test, its fast charger took 29 minutes to charge from 10% to 35%, and took about 82 minutes to hit 80%. For a full charge to 100%, it took 142 minutes.

Here are our recorded recharging time from 10% :

  • 16% – 6 minutes 36 seconds
  • 22% – 13 minutes 38 seconds
  • 25% – 17 minutes 25 seconds
  • 31% – 23 minutes 53 seconds
  • 35% – 29 minutes 15 seconds
  • 40% – 35 minutes 12 seconds
  • 45% – 41 minutes 19 seconds
  • 51% – 48 minutes 18 seconds
  • 60% – 59 minutes 34 seconds
  • 66% – 65 minutes 22 seconds
  • 71% – 71 minutes 19 seconds
  • 76% – 77 minutes 19 seconds
  • 81% – 83 minutes 14 seconds
  • 90% – 95 minutes 16 seconds
  • 95% – 107 minutes 18 seconds
  • 100% – 142 minutes 10 seconds

This gives it a battery life : recharging time ratio of 3.5 : 1 for video streaming, and 4.7 : 1 for office work.

As a general rule of thumb, you will need to recharge its battery about 17 minutes for every hour of battery life.


Dell Latitude 5520 : Verdict

The Dell Latitude 5520 is not a sleek ultralight laptop like the XPS 13, it is a large, powerful business laptop.

Its large 15.6-inch display makes it a great desktop replacement, and yet is surprisingly thin and light – it is less than 2 cm thick, and weighs only 1.6 kg.

We strongly recommend the Full HD IPS panel, over the low-resolution HD TN panel option, which would look blurry / blocky on such a large display.

Built around the latest 11th Gen Intel Core processor, with integrated Iris Xe Graphics, it offers more than enough processing power for business users for many years to come.


Business users will appreciate the availability of at least two USB-C and two USB-A ports, as well as an actual RJ-45 LAN port and a HDMI 2.0 port too!

If you input a lot of numbers, you will also appreciate the keyboard which comes with a numeric keypad, which is not available in most consumer laptops.

On top of that, the Latitude 5520 comes with a built-in physical shutter for the webcam – a must-have for security conscious users!

If you are a road warrior, we definitely recommend getting the 4-cell battery for extended battery life, which should last you about 11 hours!

All-in-all, this is a solid, no-nonsense business laptop that lets you get work done as quickly and efficiently as possible, no matter whether you are working from home, or on the road.

Finally, we should mention Dell’s truly excellent onsite warranty. With the Latitude 5520, you get 3 years of ProSupport and Next Business Day Onsite Service!

For people who count on their laptops to make a living, NBD onsite service is a MUST!
