iPhone X vs. Galaxy S8: Which Flagship Phone Wins?

Yeah, the $950 Galaxy Note 8 is technically a closer competitor to the $999 iPhone X because of the Note's higher price tag, but don't overlook the Galaxy S8 ($750) and S8+ ($850).

The Galaxy S8's display is the same size as the iPhone X's, at 5.8 inches, and both screens use OLED technology for eye-popping colors and ultrawide viewing angles. The 6.2-inch Galaxy gives you an even bigger screen than the iPhone X but still costs less dough.

Design

There's no question that the Galaxy S8 and iPhone X are two of the most beautiful phones of the year. The iPhone X has a near edge-to-edge screen up front and an elegant glass back available in Silver and Space Gray. The stainless-steel band that runs along the outside of the phone really pops while giving the handset a very sturdy feel.

Samsung Galaxy S8+ (left) and Apple iPhone X (right)Samsung Galaxy S8+ (left) and Apple iPhone X (right)The Galaxy S8's Infinity Display is even sexier, though, as it's curved and doesn't have a notch that interrupts the flow of the front of the phone, which the iPhone X has. Both the S8 and iPhone X are water-resistant, but only Samsung's phone includes a headphone jack and microSD card slot.

Lastly, at 5.5 ounces, the S8 is a little lighter than the 6.1-ounce iPhone X. In fact, the S8+ weighs the same as the iPhone X, even though the S8+ has a bigger, 6.2-inch screen. The S8+ is taller, though, which makes it more of a stretch for one-hand use.

Winner: Galaxy S8 and S8+

Display

Samsung has long been the leader in OLED screens for phones, but it's now been leapfrogged. In side-by-side tests, the iPhone X's (2436 x 1125) panel delivered a brighter image, wider viewing angles and better contrast than the displays on the S8 and S8+ (both 2960 x 1440 pixels).

Apple iPhone X (left) Samsung Galaxy S8+ (right)Apple iPhone X (left) Samsung Galaxy S8+ (right)Take this photo of a lake and surrounding mountains. On the Galaxy S8 and S8+, the sky is a deeper blue, but the iPhone X's display delivers a more-vibrant green grass and truer whites in the clouds. The clouds in the S8+'s screen look more magenta.

In addition, the brighter panel on the iPhone X gives it wider viewing angles. Under normal, indoor conditions, the iPhone X hit 574 nits, compared to 543 nits for the S8 and 475 nits for the S8+.

The displays on the S8 and S8+ do cover more of the sRGB color gamut, exceeding 180 percent, versus 123 percent for the iPhone X.

Winner: iPhone X

Cameras

Given that the iPhone X has dual rear cameras and the S8 has a single shooter, you would think this wouldn't be a fair fight. But that's not the case. Samsung's phone more than held its own when pitted against Apple's flagship.

The S8 got off to a great start with this photo of the Flatiron Building on a mostly overcast day. Its camera revealed a lot more detail in the building, while the iPhone X's shot looks drab and flat.

But the iPhone X pulled ahead when I photographed two colleagues. The iPhone's photo of Cortney and Andrew delivered warmer skin tones, while they look more washed out in the S8 image.

The iPhone X also excelled on our zoom test, but that's not a surprise given the phone's dual-lens setup. The S8 gets by with a single lens, so its 2x digital zoom photo of the Empire State Building turned out fuzzier.

It's a subtle difference, but the iPhone X offered richer pinks and more gradation of color in this close-up shot of a plumed cockscomb plant, but the S8 shot is just about as sharp.

This Galaxy S8 pulled ahead indoors, including in a photo of this Lego Man. His face is brighter on the S8 shot than on the iPhone X.

The S8 also let in more light than the iPhone X did on this shot of a raccoon decoration, and the colors look more natural.

Last but not least, the iPhone X had a slight edge on this flash shot, as the Apple phone's colors look a little warmer and more natural. The Galaxy S8 does a better job of rendering the flowers up front, but the image looks cooler and bluer overall.

To test the front cameras on the iPhone X and Galaxy S8, I took a selfie outdoors,and the difference was pretty much night and day. The S8 offers a wider angle, so you can fit more people in the frame, but the iPhone X did a better job capturing the warmer skin tone of my face and the more vibrant reds and blues in my shirt.

Winner: iPhone X

Performance

Put simply, the A11 Bionic processor inside the iPhone X is in a whole other league compared to the Snapdragon 835 chip in the Galaxy S8.

Take something as routine as loading up a new level in Injustice 2, a fighting game. In just 9 seconds, the iPhone X had us throwing punches as Batman, compared to a 13-second wait on the Galaxy S8.

We also edited a 4K video clip using the Adobe Clip app, on which we saw a bigger performance difference. The iPhone X took just 43 seconds, compared to over 4 minutes for the Galaxy S8.

It was a similar story on synthetic benchmarks like Geekbench 4, where the iPhone X notched a very high score of 10,357 versus 6,295 for the S8.

Winner: iPhone X

Special Features

The iPhone X does facial recognition right with Face ID, which uses the TrueDepth camera to create a 3D map of your face to unlock the device. The S8 has facial recognition, but it's 2D and doesn't work well in the dark. The S8 also offers iris scanning that also works well in the dark, but having two technologies to do one thing seems like overkill.

Apple iPhone XApple iPhone XThe TrueDepth camera also enables Portrait Mode selfies, which blur out the background, as well as Animoji. This allows you to mirror your expressions on one of 12 cute characters and record your voice paired with the animation and share it via the Messages app. It's creepy but fun.

MORE: How to Use Animoji on the iPhone X

The Galaxy S8 has lots of special features, including the Bixby assistant. It's not nearly as knowledgeable or versatile as Siri, but it does a very good job of trading multiple taps for a single command. Unlike the iPhone X, the S8 also lets you run two apps side by side via the multiwindow feature.

Samsung Galaxy S8Samsung Galaxy S8Speaking of windows, the optional DeX station ($121) enables S8 owners to run Android apps in multiple windows on a big monitor, complete with keyboard and mouse support. And while you can do virtual reality on the iPhone X with a third-party VR headset, the Gear VR provides a higher-quality entertainment experience. Then again, the iPhone X is ahead in iOS augmented reality apps, thanks to Apple's ARKit.

The deciding factor here is something that shouldn't be that special at all: fast charging. The Galaxy S8 comes with a fast USB-C charger out of the box, but Apple makes you pay extra for a USB-C power brick and USB-C-to-Lightning cable. Both handsets support wireless charging.

Winner: Galaxy S8

Battery Life

The iPhone X lasts longer than the Galaxy S8 but not as long as the S8+.

MORE: Smartphones with the Longest Battery Life

On the Tom's Guide Battery Test, which involves surfing the web on 150 nits of screen brightness, the iPhone X endured for 10 hours and 49 minutes. That's about an hour longer than the smartphone average, and it's in between the run times from the Galaxy S8 (10:39) and S8+ (11:04).

Winner: Draw

Value

This round is a no-brainer. The Galaxy S8 starts at a much lower $750, or $250 less than the iPhone X. The Galaxy S8+ starts at $850, and the only difference is the larger, 6.2-inch display. You can't order a model with more internal storage, but you can upgrade via a microSD card.


The iPhone X starts at an ultrapremium $999, and you can get 256GB of storage for $1,149. Yeah, I know — gulp. When you break it down in terms of monthly costs on a carrier like Verizon, the iPhone X costs $41.66 per month, compared to $31.50 for the S8, for a difference of about $10.

With the Galaxy S8+, the monthly cost is $35, so about $6 less than the iPhone X's.

Winner: Galaxy S8

Overall Winner: iPhone X

If you look at this face-off on a round-by-round basis, the iPhone X and Galaxy S8 and S8+ are pretty much neck and neck. But the iPhone X wins this close contest on the strength of its superior Super Retina OLED display, more-powerful performance and more-versatile cameras. But you can't overlook value of the Galaxy S8.

Samsung's flagship phones sport more-stunning curved designs, with a headphone jack and a fast charger included, and while their Infinity Displays aren't quite as vibrant and accurate as the iPhone X's screen, they're still great. The cameras on the S8 and S8+ also offer better HDR and low-light performance, and Samsung wins on special features. Most importantly, the S8 and S8+ cost $150 to $250 less than Apple's flagship.

Overall, the iPhone X is the best phone, but the Galaxy S8 is the best flagship for the money.

    Strongly disagree here on the display catagory. Just looking at the screens side by side can you see the advantage of the high pixel density on the s8s. Ypu also need a catagory for usability.
  • gavin.sheppard
    I thought Apple had used the Samsung OLED screen, or so other write ups declare! Set up is easily adjustable so this comparison is a bit misleading
  • drizzt545
    I thought samsung was making the screen for the new iphones? Why would there be a big difference if this is true?
  • mig6220
    Alot of Samsung features are left out.
    Gigabit Lte compatibility. Two hour movie downloaded in seconds. Samsung yes, apple no.
    Larger ram closes the speeds in real life tests. Apple has to close apps before opening, where Samsung catch up. Saw this test on another site.
    Samsung pay rewards real money back ($5-100 debit cards etc), and works everywhere there is card swipe. Apple doesn't.
    Add in other stuff-apple phones splitting while charging, latest ios update eating up battery life.... etc
    How about not leaving out features to get the desired result?
  • Mark Spoonauer
    Thanks for the comments. It’s ironic but even though Samsung supplies the OLED Screen I had different writers and editors look at both displays and all of them picked iPhone X as better. So Apple is obviously doing extra work in terms of tuning and optimization’s.
  • krazievivian
    Caucasians are pale skinned so naturally when u take a pic it'll look pale on the galaxy s8(+) but the iPhone shows warmer skin tone which you obviously do not possess so I have to give the Samsung flagship the edge...I'm not racist
  • Mark Spoonauer
    The photo may not do the differences justice, but I assure you it was unanimous when we looked at the screens side by side. The S8 is indeed sharper, but the iPhone X offers better color accuracy and wider viewing angles.
    Not sure what you mean by usability. Ease of use?

    Thanks for your comment. Gigabit LTE is a good one but that would still give the win to S8 in special features. It is worth doing a real-world speed test though on same network, so that's a great follow-up idea.

    Larger RAM doesn't make much difference in real-world tests we run. Loading apps from the background is one test, but I could see tangible difference with A11 when loading levels in games. There's simply less waiting with iPhone X.

    Samsung Pay is more widely available than Apple Pay but again that would give Samsung edge in category it already wins in special features. Plus, adoption of mobile payments isn't that great.

    According to WSJ, Just 13% of iPhone users have tried the mobile-payment service, by one estimate. Apple Pay has the highest usage at 5.5%; still below its 5.9% peak
    Walmart Pay has second highest at 5.1%, with a significant growth since last quarter
    Samsung Pay third at 3.3% https://www.pymnts.com/mobile-wallet-adoption-2017/

    So Samsung is behind both Apple and Walmart in adoption.

    As Apple uses a Samsung OLED display (but at a lower resolution to the S8) with the S8's screen having multiple setup choices. this metric should be at least a draw. So that makes the S8 the superior phone overall. Good to see Apple making an effort to try to catch up, though.
  • simon.rowell
    Your battery life score is incorrect. Based on your measurements, there is a 1.5% difference between the two phones (with the Apple having that advantage here). In real life, as you note, that's a wash - the phones should at least score the same here.
  • simon.rowell
    Apple's use of a lower resolution Samsung display in the iPhone X is something Apple doesn't like to admit for obvious reasons. However, the higher resolution of the S8, the configuration possibilities of the S8 and the beautiful and functional curved edges, clearly make the S8 the winner in that category. Color textures are too highly subjective to be a valid measurement on their own. The S8 is the superior phone overall, but it's good to see Apple waking up to the fact that their phones have been very bland for several years. That should help spur innovation rather than complacency.
  • motonsuccess
    There is always bias from American media sources towards Apple since it's an American company. This iPhone was made possible with help from Samsung.

    Such are the inaccuracies and bias of this article, that it should either be removed or corrected to show the S8 as the superior device. To do otherwise would be a disservice to everyone including Apple.
  • mikedoyleblogger
    This review is a train wreck. The title says you're comparing the S8 with the X. The photos all contain the S8+, not the S8. And the copy seems to have no idea there's a difference between them.
  • tomcollins
    BOTH WAY TOO EXPENSIVE tech advances should get cheaper- as in PCs, phones are the newest consumer debt enticement
  • ryanmitchell575
    I strongly disagree with who won the photo category. The iPhone X does have two photos that look better but, all of the other by the Galaxy 8 look much better. The flash photo is clearly better in the galaxy phone. You can almost read the gas meter in the background in the Galaxy photo, the orange is much more vibrant and all of the white in the photo from the iPhone X has a tanish pink tint to it. The last photo, while you do look better tan, is definitely more realistic. All you have to do is look at the yellow tint of your teeth in the iPhone X to see that. The iPhone looks as though they simply added a warm filter to every photo that is taken instead of actually making the camera better.
  • eosman76
    I think the S8 is a throwback in terms of style and build to the S2 and no one can argue about the processing power of the Apple X compared to it, but we have often seen technical products that are comparatively more highly specified to their rivals not selling as well in the global market place due to the fact that as consumers, we need our products to meet our expectations, which is not always achieved because the software or app is not able to take full advantage of the product with the superior hardware. One thinks of the console wars of the late 80's and early 90's and so on to know what happened there. I personally think that we will get to an era within the next 5-10 years where these smartphones will replace the tablet or the notebook and do it all as Bill Gates predicted some 20 years ago, and these generation of smartphones are merely a testing ground for what is about to take off when we are in our 30's 40's or 50's respectively.

    Bro. You got the hoompa loompa tan going on in that iphone x pic xD "shows the vibrant colors of my shirt". Dude just stop. Get off the wheel. You ain't fooling no one.
  • bigtalon
    Real question:

    Does it matter?

    iPhone X uses Samsung technology, Thus Samsung is going to make Billions from the sale of the iPhone X, and Billions from it's own phone. This is the reason Apple is beginning to sink, they are using Samsung Technology to make their phones, so Samsung is profiting from both sides of the coin. Quite the marketing scheme haha. People comparing the 2 phones cracks me up, Because the iPhone X is always going to be behind the Samsung Phone, because Samsung throws them the last gen technology while using the new gen for themselves.
