So before you’ve even decided what new accessories you want to get, you are still in the process of upgrading your Smartphone.

Have you decided you’re going to just buy a new one or cant you decide?

Of course if you are a loyal companion to either the iPhone X vs Samsung S9 then you have already made up your mind. Unless of course you’re now curious about which the better phone is.

So what is the better phone? The iPhone X vs Samsung S9. I’ve read up on quite a few reviews with regards to either the iPhone X or Samsung S9 and when comparing hardware to software, well you’ll see.

Below is a list comparing the hardware of the iphone X vs Samsung S9. As far as the hardware goes the Samsung S9 wins hands down. We then take a look at the performance the iPhone X and Samsung S9.


AMOLED is an active-matrix organic light-emitting diode. It adds a layer of semi conducting film behind the OLED panel which allows it to more quickly activate each pixel.

The increased speed makes it ideal for larger, higher definition displays with a lot of pixels. As you can see the iPhone X vs Samsung S9 are tie on this round, both with a 5.8 inch display.

If you’re wondering what the difference is between the iPhone X or Samsung S9 AMOLED there isn’t any, the word “SUPER” is just the brand name for Samsung s AMOLED.

The touch screen on both the iPhone X vs Samsung S9 consists of a TSP (Touch Sensitive Panel). The TSP is responsible for touch sensitivity in touch screen devices.

Both iPhone X vs Samsung S9 can display HDR content from Netflix, but Amazon Prime and YouTube HDR support is limited to the Galaxy S9.


The Samsung Galaxy S9 has a resolution of 1440 x 2960 pixels and a pixel density of 570 PPI. This means that there are a lot more pixels spread across the screen than the iPhone X 2436 x 1125 (458ppi)



What is a Pixel

A pixel is the smallest element that can be displayed on a screen. To be more simple, it is just a single dot on a display or a screen.




What do we mean by Resolution Screens or Displays are measured in centimeters and inches. The measurements used to determine your resolution are measured diagonally across the screen, meaning from corner to corner.

The Resolution refers to size of the display in terms of pixels. e.g. Resolution of the Samsung S9 is 1440 × 2960 pixels. This means that the there are 1440 pixels horizontally and 2960 pixels vertically.

Therefore there are a total of 4,262,400 pixels in the display of the Samsung S9.

The iPhone X  has 2,740,500 pixels which is just over half of that of the Samsung S9. The S9 wins that round hands down! Although the Samsung S9 has more vibrant colours and saturation its seem as tho the iPhone X has better hues.

The iPhone X also has the ability to alter the colour temperature of the display according to the surrounding environment.


What is the difference between pixel density and resolution?

Pixel Density is usually measured in PPI (Pixels Per Inch) which is how many pixels you have per inch on the display. The higher the pixel density the higher the sharpness the content displayed on screen will be. Pixel Density is calculated based on the resolution and size of the display


Aspect Ratio

Aspect ratio is the term used to describe the dimensions of an image by comparing the width to the height and expressing it in ratio form.

The aspect ratio of your images are primarily determined by the dimensions of your camera’s sensor.

Smartphones these days are able to crop  images to different size aspect ratios.


Why aspect ratio matters

Why does aspect ratio matter? It’s all to do with the piture, the sides of the frame and the amount of empty space around the picture. An awareness of the characteristics of the aspect ratio of your particular camera can help you compose better images. It also helps you recognise when cropping to a different aspect ratio will improve the composition of your image.



Rear camera

What does aperture mean?  A camera’s aperture refers to the size of the opening through which light enters the camera and reaches the sensor.





What is an F-stop?

An aperture is measured in f-stops. This is represented by an “f” and a number eg 1.5 (f/1.5).

A ratio of the focal length is divided by the opening size.

The smaller the f-stop, the wider the opening which allows more light to reach the sensor. The Samsung Galaxy S9 comes fitted with a 12 megapixel rear camera capable of switching between f/1.5 – f/2.4.

The iPhone X also comes fitted with a 12 megapixel rear camera but it only has the capability of switching between f/1.8 – f/2.4.

What this means is the wider the lens can open the more it allows the light to hit the camera’s sensor. The more light means the better the camera will perform when in low light.

The lower the F-stop the wider the aperture which is why the Galaxy S9’s f/1.5 is better than the iPhone’s f/1.8.


Front Camera

Now that you understand what aperture and F-stop means you can see once again the Samsung S9 has out done the iPhone X.

Again as far as camera’s go with the Samsung’s 8 Megapixel f/1.7 as apposed to the iPhone X’s 7 megapixel camera with f2/2.

However, that been said once again due to performance and the capabilities of the features of the iPhone X it tends to take better pictures.

The iPhone X comes equipped with both a wide and zoom lens, this allows for better framing of shots. Although, using the zoom function does reduce image quality.

The f/1.8 aperture on the iPhone X allows it enough light to reach the sensor, without slowing down the shutter speed and introducing camera shake. The Galaxy S9 has only the one lens (unless you choose the Plus model), and therefore has less zoom versatility.

The S9’s clever trick is a variable mechanical aperture between f/1.5 and f/2.4.  a lens on a DSLR, it can open or close its diaphragm to let more light reach the sensor.

The f/1.5 aperture provides more light than the iPhone X’s f/1.8. The variable aperture will also have an effect on ‘bokeh’, which is the background blur that helps separate your subject from the background.



Currently, the most powerful chips out there are the Snapdragon 845 the Exynos 9810 the A11 Bionic and the Kirin 970.

Apple A11 Bionic

The A11 Bionic is the smallest out of all its competitors chipsets. It measures at 87.66mm2, as far as performance is concerned, no Android-based chip has ever managed to better Apple’s manufacturing feat. The A11 Bionic defeats its competition by quite a far margin.



Exynos 9810

This chipset comes the closest to the A11 Bionic. It is currently the most powerful chipset that has been manufactured for Android devices. It is only currently found in the Samsung S9 and S9 plus. So it seems in the not so far future Samsung might even come out on top with this too. But for now the IPhone takes this win.



RAM (Random Access Memory) is where your mobile stores its data such as running programs and the data for those programs. Also, referred to as your internal memory.

If your RAM becomes full this will cause your phone to run slower. It is recommended that you clear you’re ram which will reset running apps and speed up your phone.

Temporary stored data can be released and be reallocated to other applications. This happens only once you have cleared the cache.

You will notice improved performance on your device. The lager the Memory or RAM, the faster your phone will be. The Samsung S9 has 1GB more RAM than the iPhone X, making the Samsung yet again, the winner.


This refers to the total storage of your phone, both external and internal. This is the space that is available for you to save you files, apps, songs and videos. The larger your storage the more space you have available to save all your goodies.


OK OK so, I got all of this information directly from Apple Insider who themselves did several (8 to be exact) test on the battery life of the S9 and the iPhone X.

To quote their own words: “When looking at the tests overall, its safe to say that the Samsung Galaxy S9 is undoubtedly superior to the iPhone X in terms of battery life.


Samsung is doing some interesting things with its speakers as well. On the S9 they’re front-facing and are tuned by AKG, plus they support Dolby Atmos for a pseudo surround-sound effect. We still think the speakers on the iPhone X are better and thesound is richer and doesn’t distort at high volumes.

    Undoubtedly the Samsung is superior to the iPhone. Heck, they even have an “s” that means Super. What does the iPhone X stand for? Just a roman numeral that means we are charging you more for less.
    Samsungs are indeed a great phone. You captured all the details of both party and made it easy for people to see the truth. Some will still argue the iPhone is better and that is because they can’t handle the plain truth.
    Thank you for this beautifully detailed review.

    Thank you Leith for your well articulated post. It was quite scholarly and and technical but I feel that due customer loyalty the buyer may not so much care for the comparisons. However a new buyer seeking to buy ‘the best’ phone may be patient enough to go through through rigors of such comparative analysis. All said you have made a fantastic presentation.
