Design & Display

Even though both of Samsung Galaxy S9 and iPhone X are designed as full screen (all screen), Samsung Galaxy S9 is 4.1 mm taller, 2.2 mm narrower and 0.8 mm thicker than iPhone X. Because Samsung Galaxy S9's height is 147.7 mm while iPhone's is 143.6 mm, Samsung Galaxy S9's width is 68.7 mm while iPhone X's is 70.9 mm and Samsung Galaxy S9's thickness is 8..5 mm while iPhone X's is 7.7 mm. However, with Samsung continuing to use a thicker top bezel, Samsung Galaxy S9 has no notch on screen, which owns its concise beauty while iPhone X has notch on screen.

With the process of Apple A11 Bionic, iPhone X is such a monster and runs very quickly, however, Samsung Galaxy S9's is not bad as well. Samsung Galaxy S9 is equipped with the latest processor called Snapdragon 845. Samsung Snapdragon 845 has 8 cores (4 are 2.8 GHz and the other 4 are 1.7 GHz.) while Apple A11 has 6 cores (2 are 2.35 GHz high performance cores and 4 are slower efficiency cores.)


Samsung Galaxy S9 does not have the dual rear camera system like iPhone X (two 12MP cameras with 1x and 2x optical zoom lenses). If you want the dual rear camera, you can consider to buy Samsung Galaxy S9+, which is bigger with better performance. However, Samsung S9's 12MP rear camera has double aperture lens which can automatically switch between f/1.5 and f/2.4 according to the shooting conditions and also the multi-frame noise reduction technology can provide very good low light performance.

What's more, Samsung Galaxy S9 can shoot 4K videos like iPhone X and it supports 960fps super-slow-motion video mode which is quite amazing while iPhone X only supports 240fps.

Face Recognition & Fingerprint Recognition

Both of iPhone X and Samsung Galaxy S9 has Face Detection, however, iPhone X has no fingerprint recognition. As is known, iPhone X has no Home button, which is the place where Apple devices stores and verify fingerprint. Unlike most of Android devices like Samsung Galaxy S9/S9+ to put the fingerprint recognition to the back of the device or under the screen, Apple's iPhone X completely get rid of it and now iPhone X can only process through face recognition.

iPhone X requires many people to abandon Touch ID and completely rely on Face ID to improve the safety of device. However, tests indicate that facial recognition is not that reliable and also it is complex. For example, it should work at the darkness and also it can handle the change in dress, expression, hair and etc.

Samsung Galaxy S9 has a less complicated facial recognition than iPhone X, but it certainly provides fingerprint recognition for backup, which is better than iPhone X. Besides, please be noted that this is not to say that it is not good to put fingerprint recognition behind Samsung Galaxy S9, actually it is a little hard to use it.

AR Emoji

When iPhone X was announced, Apple has spent some time demonstrating a new feature called Animoji, which uses complex processor arrays to combine your facial movements with animal expressions. This looks stupid but interesting. Clearly, Samsung thinks it needs something similar, so Samsung Galaxy S9 has a new feature called AR Emoji. Even though S9's front camera doesn't have a 3D scan like Apple, it can still track your facial expressions to achieve dynamic expression. By the way, personally, the AR Emoji are much ugly than Apple's Animoji, and the general consensus is that they look a little creepy.

Waterproof & Dust proof

Both of Samsung Galaxy S9 and iPhone X are equipped with dust proof and waterproof, however, Samsung Galaxy S9 is far ahead. iPhone X's waterproof level is IP67 and protect iPhone X from water damaged in a depth of 1 meter in the water. However, Samsung Galaxy S9 is higher water resistant with IP68 and the water-resistant property of Samsung Galaxy S9 supports to be water-resistant up to 30 minutes in a depth of 1.5 meters in the water. And IP68 is the highest level of waterproofing.

Both batteries of iPhone X and Samsung Galaxy S9 are not replaceable and support quick charging and wireless charging. Besides, Samsung Galaxy S9 supports and provides a Quick Charge 2.0 (QC 2.0) while iPhone X's quick charger requires additional purchases.


Samsung Galaxy S9/S9+ and iPhone X are both excellent flagship smartphones with their own unique features. While the iPhone X has a slightly more compact design and powerful processing power, the Samsung Galaxy S9 has a larger and more vibrant display, a mechanical dual aperture camera that is capable of better low light photography, and expandable memory.
