OnePlus 6 vs Huawei P20 Pro: A very decent comparison

29 May 2018 5

Both the Huawei and OnePlus are undoubtedly two Chinese brands which achieve huge success in western markets during last few years. Both the devices flagships are powerful enough to challenge the existing big brands. This year Huawei delayed their flagships P20 lineup announcement for a month. Last year Huawei took the MWC stage to showcase their P10 lineup but this year the company delayed the announcement till March 2018 to announce P20 series. The P20 Pro is rated as the best flagship announced so far this year. The P20 Pro camera setup makes it the best camera-centric smartphone. The P20 Pro took the Samsung's Galaxy S9 Plus throne as the best flagship smartphone of H1 2018.

On the other hand, OnePlus just announced their next big flagship as OnePlus 6 on May 16th. As expected the device is powerful enough to challenge the existing big players and certainly, it can challenge the Huawei's P20 Pro. The best thing about OnePlus flagship is once again it's price tag as it is available at almost half price tag of P20 Pro. So if you are amongst those who are looking to grab a new flagship smartphone, they would surely consider the P20 Pro and OnePlus 6 as well. The P20 Pro takes a significant lead in the camera and battery section but are these changes enough to differentiate it from the competitors or not.

Today we will put the latest OnePlus 6 in head-to-head competition against the P20 Pro to know in detail the real pros and cons of both the devices. We are also hopeful this comparison will certainly help you better understanding whether you should grab the premium flagship P20 Pro or the flagship killer OnePlus 6. Without any further delay, let's start with the design of both the devices.

Undoubtedly the P20 Pro and OnePlus 6 are a big step from their predecessors. The P20's predecessors feature a unibody aluminum design whereas the P20 Pro features a glass and metal sandwich design which looks quite striking. Huawei ditched the metal in favor of shiny glass. The device is available in a number of striking colors option. We can easily claim it to be one of the best-looking flagships of this year.

OnePlus 6 also brings a huge change from the predecessor as it also comes with metal and clad design instead of unibody design of OnePlus 5/5T. To further refine its glass rear OnePlus brought special 5 layers coating that's why it feels much different from regular smartphones with glass rear. The OnePlus 6 dimensions are 155.7 x 75.4 x 7.75mm and it weighs 177g. On the other hand, the P20 Pro's measurements are 155 x 73.9 x 7.8mm and weigh 180g. So both the devices are not only quite close to each other in terms of dimensions but also weighs almost same. No matter which smartphone you opt overall footprint of both the devices is exactly similar.

The P20 Pro is IP67 certified which means it can resist up to 1.0 meters deep water for 30 minutes without any damage whereas the OnePlus 6 doesn't have any IP-ratings instead the device can resist shower and rainwater. Both the P20 Pro and OnePlus 6 have notch at the top of the display.

The P20 Pro has triple camera setup on the rear placed vertically on the top left corner. The OnePlus 6 features dual cameras on the rear side, the sensors are aligned vertically in the center. As far as fingerprint scanner is a concern the P20 Pro has a scanner on the front below the display whereas the OnePlus 6 scanner is on the rear side. The P20 Pro lacks the traditional 3.5mm headphone jack due to the inclusion of waterproofing whereas the OnePlus 6 retains the traditional headphone jack. In terms of feeling the OnePlus 6 looks more solid but the P20 Pro takes lead in looks due to striking colors options like Twilight.


Both the devices have full front-facing AMOLED display but that's where similarities end. The P20 Pro features a 6.1-inches display panel with a Full HD+ screen resolution of 1080 x 2244 pixels. The display aspect ratio is 18.7:9. On the other hand, the OnePlus 6 sports a 6.28-inches display panel with a Full HD+ screen resolution of 1080 x 2280 pixels. The display aspect ratio is 19:9.
Surprisingly both the devices don't have Quad HD+ screen resolution but the good thing is both the companies opted AMOLED display panels which provide better colors saturation, sharpness, and deep blacks than LCD panels. The reason behind awkward aspect ratio is the notch at the top of both the devices.

Those who don't like the notch at the display they can replace OnePlus 6 notch with a black bar via settings whereas P20 Pro doesn't offer any settings to remove it. Both the devices panels are quite vivid with great colors accuracy but the OnePlus 6 provides more display customization options than P20 Pro.


Under the hood, both the devices are packed with the best possible hardware. The OnePlus 6 is running on the Qualcomm's Octa-core Snapdragon 845 SoC. The base variant has 6GB RAM with either 64GB or 128GB storage whereas the top of the line variant has 8GB RAM and 256GB storage. The top-tier variant is available only in Midnight Black variant. The built-in storage of OnePlus 6 isn't further expandable via MicroSD card.

Huawei is one of those OEMs who uses their own chipsets. The company's own Kirin 970 SoC is powering the device with 6GB RAM and 128GB storage. The P20 Pro supports memory expansion using MicroSD card. The Kirin 970 SoC was introduced last year with the Mate 10 lineup and so far it is powering a number of Huawei and Honor flagships. It is amongst the best SoCs in the market but not as powerful as Snapdragon 845.

The OnePlus 6 is specially optimized to provide optimal results in most of the scenarios that's why in head to head competition on the basis of performance the OnePlus 6 has an upper hand. However, the P20 Pro's option to expand native storage is certainly a great advantage over the P20 Pro.

Screen resolution 1080 x 2280 pixels 108 x 2244

The P20 Pro lights are kept on by a gigantic 4,000mAH battery cell whereas the OnePlus 6 has 3,300mAH cell. Although the OnePlus 6 battery is specially optimized to provide a great battery life it won't last as long as the P20 Pro. The OnePlus 6 supports the company's Dash Charging tech where the P20 Pro features Super Charge tech. In terms of fast charging, the Dash Charging tech is certainly better than Huawei's tech.

Unfortunately despite having glass rear both the devices lack support for wireless charging. On a single charge, the OnePlus 6 easily completes one day on single charge whereas the P20 Pro lasts two days easily on normal usage. So if you are looking for one of the best battery life the P20 Pro is certainly a better choice.


In the camera department, the P20 Pro is far better than any other flagship in the market. It takes lead over all competitors with a huge margin, it not only takes lead in quantity but also in quality as well. The P20 Pro is featuring triple camera setup on the rear. Although you may not find all of them use the working of all three certainly makes a difference here.

The primary sensor is 40MP RGB module whereas the secondary sensor is a 20MP monochrome sensor and the third separate sensor is an 8MP telephoto lens to provide optical zoom up to 3x. The P20 Pro triple cameras setup not only captures stunning shots in stable light conditions but also works great even in low-light conditions.

The telephoto lens provides 3x optical zoom but you expand it up to 5x hybrid zoom. Undoubtedly the P20 Pro is one of its kind smartphones in the market which provides hybrid zoom up to 5x without any noise and amazing clarity. Huawei optimized the results using AI but in many scenarios, the results show overblown colors, however, the good thing is you can disable this option as well. Until last year the Huawei Pixel 2 was regarded as the best camera phone in the market but this year Huawei P20 Pro takes lead with a great margin.

On the other hand, the OnePlus 6 features dual rear cameras. Both the sensors are main cameras of 16MP+20MP with f/1.7 aperture. OnePlus didn't bring any change as far as cameras are a concern, they retained the similar setup of OnePlus 5T but obviously, the brought few refinements. The primary 16MP sensor now features optical image stabilization and also the main sensor is 19% larger as opposed to last year. The Oneplus 6 doesn't bring any option to disable the overblown colors.

The P20 Pro front-facing selfie camera is 24MP module whereas the OnePlus retains the 16MP sensor with f/2.0 aperture. The P20 Pro brings native support for protrait mode whereas OnePlus 6 will soon receive an update for portrait mode support.


Like most of the latest Android flagships, both the devices are pre-installed with Android Oreo straight out of the box. However, the custom UI layer is different on both the devices. The Huawei's custom UI layer is EMUI 8 over the stock version of Android, it is undoubtedly one of the heaviest custom layers with quite near look to Apple iOS. The EMUI was certainly one of the major issue related to Huawei UI but Huawei brought significant improvements with the EMUI 8. The bloatware level is quite low as opposed to earlier versions.

The OnePlus 6 is pre-installed with Oxygen OS based on Oreo. It is way cleaner than the Huawei's custom version of OS. Also, it is one of the first smartphones which support Android P developer preview. This indicates it will be amongst the first smartphones to receive the Android P update. If you are found of stock Android OS, you will find Oxygen OS a better choice with more options for customizations.


The pricing is certainly one area where OnePlus always takes lead over the competitors. This year once again OnePlus 6 is one of the cheapest flagships in the market with the best possible hardware, design and superb display. OnePlus smartphones are known to be flagships killer as they brought the best at fraction of price tag.

The OnePlus 6 base variant with 64GB native storage costs $529, it is $30 expensive as opposed to last year's OnePlus 5T. Other variants are $50 expensive if you double the storage. On the other hand, the P20 Pro is one of the most expensive smartphones from Huawei as it costs £799 in the UK whereas for the international customers it costs above $800. So if you are looking for a better value for your hard earned money the OnePlus 6 is certainly a better choice.


Both the OnePlus 6 and P20 Pro shares a lot of aspects. In terms of design, both the devices have glass and metal sandwich design with a notch at the top of the display. The display panel on both the devices is OLED with Full HD+ screen resolution. Under the hood, both the devices have the latest best hardware with at least 6GB RAM. As OS both the devices is pre-installed with Android Oreo. Both the device support fast charging. That's where similarities between the two devices end.

We have to admit OnePlus paid special attention to design, display and build quality in last few years that's why OnePlus 6 can be regarded as one of the smartphones with top-notch build quality. The P20 Pro takes lead in IP-ratings, the best Leica-certified camera-setup in the market and the fairly large battery cell.

Last but not the least pricing is certainly a key factor in the success or failure of any smartphone. For those who want a budget-friendly flagship will consider OnePlus 6 as a good alternative to P20 Pro. In case if you don't have any issue related to pricing the P20 Pro is surely amongst the best smartphones in the market especially if the camera is your first priority.
