Apple iPhone 8 vs iPhone X in 2021: Which Oldie Is Better?

author Luis Silva (March 2020 Updated: May 2021 - 8 min. reading time)

The iPhone X will cost you more, but it's the best of the two.

It comes with better glass protection and a better display.

What else do they have to offer?

The iPhone X also comes with an AMOLED, larger (+1.1") display, better peak brightness, a telephoto lens (+52 mm), and more RAM (3GB vs. 2GB). But the iPhone 8 features a lightweight body (26 g./0.92 oz less).

How much more will the iPhone X cost me?

If you're considering a new and unlocked smartphone, you'll have to spend approximately $209 more.

Is the iPhone 8 still worth getting in 2021?

The iPhone 8 is still one of the best phones you can buy in 2021 (depending on your budget), even more so if you can find it with a great deal. Nevertheless, you should also check other phones like the iPhone 12 because it has better performance, better cameras, more security updates, faster charging, more RAM, and better display.

Is it worth buying the iPhone X in 2021?

For a phone introduced in 2017, the iPhone X still has good camera. It still makes sense in 2021, but you'd be better off with (again) the iPhone 12 as a daily driver because it has better performance, better cameras, more security updates, faster charging, and more RAM.

Read on to learn more about their differences, how they compare to similarly priced rivals, and how the industry is scoring their specs.

Apple introduced its iPhone X model in October of 2017. Meanwhile, Apple's iPhone 8 started to sell one month sooner.

We've run down the specs, design, price, and much more in this guide to help you choose between the iPhone 8 and the iPhone X.

These two have a considerable price difference between them. Keep this in mind when comparing both iPhones.

Down below, there's a "Tek-Score" in every analyzed section of these models. For a quicker analysis of how far they are from each other, we'll consider all their specifications. The global score will help you compare them to other phones because you'll probably have other phones in mind.

The weight of each section

We've based our score on a study from Globalwebindex.com on what features users value on new smartphones. But you'll be able to define how the global score is composed based on your preferences. You can go there right now, but I encourage you to keep reading.

For additional information regarding our smartphone comparisons, check this FAQ.

You'll also see a progress bar underlining some features. That's to show how they compare with other smartphones with similar prices.

By clicking here: you'll see which ones we've analyzed, but we only include smartphones with price tags from -20% to +20%.

Some items are clickable, and they'll get you to several top 10 tables for up to seven different budgets.

Which One Has The Best Performance?

About performance: Geekbench 5 scores the iPhone X 6% ahead of its sibling in the multi-core ranking. On daily usage, you wouldn't be able to notice any relevant differences between them.

You can also count on the iPhone 8 to have one of the best performances around by comparing it with other smartphones from this price range. It got a score of 2245, compared to the usual 1596, or close to that.

There isn't much to see here, as both share the same core: the Apple A11.

This also isn't a GPU battle because they all have a proprietary Apple GPU.

Both phones run on iOS 11 out of the box.

Which Phone Has The Best Display?

The iPhone X is the winner here, and it should be noticeable.

While the iPhone X got a 5.8-inch AMOLED display, the iPhone 8 got a smaller LCD display with 4.7-inches. It all comes down to personal preferences for both the display type and size.

If you're trying to keep your phone's display small, the iPhone 8 is your holy grail. Other similarly priced smartphones just aren't that short.

The iPhone X benefits from a higher resolution, at 1125x2436 pixels, while the iPhone 8 has 750x1334 pixels.

The iPhone 8 has one disadvantage against most smartphones in its class: Its pixel density evens out at 22% below the rest.

Just a tiny drop may shatter your phone, so let's get the elephant out of the room. The iPhone 8 is shielded with an Ion-strengthened glass. The iPhone X display is preserved with a Corning toughened glass.

Unfortunately, none of them support the Always-On display feature.

If you don't manually set the screen brightness, the iPhone 8 can go up to 530 nits, and the iPhone X can top at 726 nits.

Be aware that anything less than 500 nits just isn't your best option for HDR content and outdoor readability. About HDR content: The iPhone X supports HDR10 videos.

Considering the iPhone 8, you should know that 86% of its rivals have an AMOLED screen, and 77% have an Always-On display. On the contrary, none of them have over 60hz of refresh rate, and only 5% of them feature Gorilla Glass 6 or Victus.

Concerning the iPhone X, just so you know, 88% of its rivals can play HDR content, 96% have an AMOLED screen, and 92% have an Always-On display.

Which Phone Has The Best Cameras?

Apple iPhone 8 back transparent png Apple iPhone X back transparent png

We can safely state that both phones have similar cameras.

Things are different when it comes to lenses. Apple's iPhone 8 can record videos at up to 2160p. It also has a shooter with 12 Megapixels, an aperture of f/1.8, a 28mm wide-angle lens, four flash LEDs, HDR capabilities, and Optical Image Stabilization.

Want to know about its selfie capabilities? It has a 7 MP (f/2.2) shooter and a standard lens.

Unfortunately, DXOMARK hasn't tested this camera, but by doing some math, it scored 103*. By including its digital zoom abilities, that will go up to 107**.

I hope this helps: all of its rivals have an ultra-wide-angle lens. Though only 23% of them come with a telephoto lens and come with Optical Image Stabilization.

If you want to compare both 12 Megapixels cameras, you won't find many differences from the iPhone 8. Its second shooter has a 12 Megapixels sensor with an aperture of f/2.4 plus a 52mm telephoto lens.

The front-facing camera features a 7 MP shooter with an aperture of f/2.2 and a 32 mm lens.

The guys over at the DXOMARK labs scored this camera with 109 points. And if we consider its telephoto lens, this score goes up to 117** points. If you want to know more about it, check it here.

Furthermore, just like the other device, all of its rivals can record videos in 4 or 8K, have an ultra-wide-angle lens, and feature Optical Image Stabilization. Additionally, only 16% of them feature a macro lens.

The iPhone X has one significant benefit over the iPhone 8 in that it includes a telephoto lens with an optical zoom of about 2x. It will enable you to get a closer view of the subject before taking your picture.

*DXOMARK knows how to test these shooters out. Unfortunately, they don't test every smartphone camera out there. So when I find one such shooter, I score every camera spec (like sensor size, lenses, and so on) to get a similar global score. You should give it a maximum of 2 points (up or down) margin of error.

**Please take this with a grain of salt, particularly on mid-end cameras with less than 40MP and no zoom lens. They just revised their formula, and I only have few reviewed devices to deduce a compatible score.

Who has the best frame?

The iPhone 8 does stand out because of its weight and the number of color options. But they're not that far apart.

The iPhone 8 has a height of 138 mm (5.44 inches) and a width of 67 mm (2.64 inches). The Apple iPhone X, however, is a bit wider. Precisely 0.12 inches (3 mm) and a bit taller: 0.20 inches (5 mm).

When it comes to thickness, there's no difference here: 7 mm (0.28 inches). In addition to that, the iPhone 8 is indeed small. About 20% smaller when compared to the average phone for its price segment.

The glass rear on these phones makes them feel great on the hand. The iPhone 8 weighs 148 g. (5.22 oz), while its sibling is 26 g. (1.02 oz) heavier. If you're curious, I've come up with an adapted "display size to phone weight ratio" score. The iPhone 8 got 3.5, meaning it's kind of weighty for its display size. The iPhone X, in its turn, has 4.5, so nothing to state here.

You can have the iPhone 8 in Silver, Gold, Space Gray, and Red. And you can compare that with the Space Gray and Silver, which comes with the iPhone X.

If you like having a big phone, you should consider the iPhone X. If not, then you may be out of options here.

Does a fingerprint scanner matter to you? There's one on the front of the iPhone 8 but not on the iPhone X.

You'll still have Face ID on the iPhone X. At least Apple opted for the Face ID sensor instead.

The iPhone 8 is water-resistant in up to 1 meter, much like the iPhone X. That shouldn't last over half an hour, and it's freshwater in standby mode only.

Which has the best battery?

The iPhone 8 does have a battery capacity of 1821 mAh versus the 2716 mAh of the iPhone X. But as reported by GSMArena, you shouldn't expect notable differences here.

That's what you can expect from the iPhone 8 after charging it up:

  • For 1 hour of talking, 1 hour of web browsing, and 1 hour of video playback, you'll be at 75% of the battery charge.
  • For 1 hour of talking, 3 hours of web browsing, and 1 hour of video playback, you'll get down to 59% left.
  • By talking for 1 hour, browsing the web for 1 hour, and playing videos for 3 hours, you'll be with 57%.

And this is how the iPhone X handles these tests:

  • By talking for 1 hour, browsing the web for 1 hour, and playing videos for 1 hour, you'll still have 76% left.
  • If you do 1 hour of talking, 3 hours of web browsing, and 1 hour of video playback, the battery charge will be about 54%.
  • By talking for 1 hour, browsing the web for 1 hour, and playing videos for 3 hours, the phone will have 60% left for the rest of the day.

Alright, that's not a reason to make the iPhone 8 shine, but Apple did everything in its power to save as much "power" as possible (pun intended). Its "battery to device size" rate is 7.8.

One more thing about battery life on the iPhone X: it is way below what you find on their rivals. These results show that it lasts about 13% less.

If you're wondering about their charging speeds, these two can charge at 15watts.

Both phones support wireless charging at 5w.

Which has more storage?

None of them has.

The iPhone 8 has 64GB of internal storage and 2GB of RAM. Unfortunately, Apple didn't include a MicroSD slot. This shouldn't be an issue for most of us. Also, similarly priced adversaries usually have more RAM and more storage. They have 5GB of RAM and 80Gb of storage on average, but you can find better options.

In its turn, the iPhone X has 3GB of RAM and 64GB of integrated storage. There's also no expandable storage here. This may not be enough for serious smartphone users. Again, you can effortlessly get more RAM and more storage from almost all of their competitors. 8Gb for RAM and 148Gb for storage, on average.

Neither storage nor RAM should be an issue on both iPhones. However, if you plan to store some movies or record tons of videos, you'll find out that 64 GB won't be enough for you.

Features iPhone 8 iPhone X
Internal (GB) 64GB
Micro SD No No

*Internal Storage + 256GB Memory Card (Max: 512GB).

Which is the most connectivity-friendly?

They also don't stand out on any of these features.

Bluetooth 5.0 is here, on both of them. As for the NFC chips, both have them.

If you got used to counting on the good-old 3.5mm headphone jack, forget about it. You can buy an adapter, but the wireless buds are your only option.

You can connect them to LTE networks. If you really want to give 5G a try, you should also consider the iPhone 12 Mini.

Which is more affordable?

You're likely not considering the iPhone 8 to make all your pennies count. That, of course, depends on the place and the deals that you'll eventually find. If you're going for the iPhone X, you'll end up paying a bit more, but that's probably something you already knew.

Don't worry, because the following tables will help you make up your mind.

Want to know about that global score? Just so you have an idea, take a look at where its adversaries average. They're in the ballpark of 5.4 for the iPhone 8 and 6.8 for the iPhone X.

Verdict: What Makes the Apple iPhone X Stand Out?

You should be able to find any of these with a price tag a lot lower than when they came out in 2017. Although it will be hard to find any of these in a pristine new condition, they sure worth the time you're spending looking for them.

Apple clearly went for a more premium approach with the iPhone X. This is one of those rare times that you get a smaller body with a bigger screen, and that does make a difference here. Apart from that, you get quite the same device.

But there are a few things that I don't consider, like price, brand value, size, resell value, OS (iOS or Android), user experience, updates, RAM (included on performance), battery to phone size, display size to weight, network (LTE/5G), and biometrics.


Progress bars explained

#1: A big red progress bar means that this value is way below the average. In this case, it's 28.85MP, and the iPhone XR is 16.85MP below the average.

#2: In this example, the XR is just 0.36mm below the average, that's why the red bar is almost unnoticeable.

#3: On the other hand, the SE 2 is 1.8mm above (hence, the green bar) the 26.2mm of average.

#4: Performance-wise, the SE 2 is well above the average (of 2512) for its price range. That's the reason the green bar is that long.


"Display size to phone weight" ratio explained

This indeed is a "display size to phone weight" ratio, but because every phone ended up somewhere between 0.0272 and 0.0421, I've amplified (adapted) those values so they would fit in a 0-10 scale. As of now, the best smartphone is the Samsung Galaxy A40, with 140g. (4.94 oz) for a 5.9 inch display. It got a score of 9.92. While the worse device is the iPhone 8 Plus, which weighs 202 g. (7.13 oz) and has a 5.5-inch display. It ended up with a score of 0.75.

Please, be aware that this score is subject to change if and when a new smartphone comes along that ends up being outside of this scale.


"Battery to device size" ratio explained

This score should give you an idea about the energy footprint of the devices you're considering. It reflects not only the hardware and the energy that it requires but also the amount of energy that the battery can deliver.

The major spenders on any device should be the display and the SoC. But everything from a notification led to its modems need to be optimized, or else, the OEM should simply include a bigger battery as a compensation. Unfortunately, it isn't always possible due to size limitations. But in the end, if a particular OEM can do a good job and give you excellent battery life on a small device, so should everyone else. That's why I've added a "battery to device size" ratio. But since the real scale went from 119 (for the Galaxy S10e, Snapdragon variant) and up to 164 (for the iPhone 7 Plus), I've decided to convert them so they would fit in a 0-10 scale, being 0 the worst device, (the iPhone 7 Plus) and 10 the one every OEM should look up to.

As an example, Apple did an excellent job on the iPhone 7. It has a score of 8. Despite having a small capacity, the hardware is well optimized, and it still gives you decent battery life considering its size. The iPhone 7 Plus, on the other hand, with those bezels shrinking its display size, clearly could've been the #1 in our top 10 list of best battery devices if Apple simply filled all that empty space with a bigger battery.

As a side note: I haven't included the dept of the devices in this formula because even if a device ended up being 1mm/0.03 inches thicker, it wouldn't matter that much to those who really value battery life.

Please, be aware that this score is subject to change if and when a new smartphone comes along that ends up being outside of this scale.

Formula deviation

Since the guys at DxoMark don't review every camera out there, I've come up with a formula based on the ones that they do rate, so I could get an equivalent score for the ones they don't review. After testing it against these cameras, I got the deviation between that and their DxO score.

As you can see, most cameras sit between 1 and -1, while a few of them go up to 2 or -2. That means it's reasonable to assume other similar cameras that they don't review to, in the worst-case scenario, be anywhere from -2 to 2 points from the score that the formula gets.

For example: Given that the Pixel 4 got 117 points and that the Pixel 4 XL share the same year and camera specs, it's reasonable to expect a score of 117 too. But in reality, if they do review that camera, it may end up anywhere between 115 and 119.

Be aware that at DxO, they give a score based on their opinion, not based on any formula. That's why I think there's an odd difference of 6 points between the iPhone 8 Plus and the iPhone X. In theory, they should have the same camera.

I'm guessing that the Mi 9T Pro got a deviation of 7 points because they tested its Chinese variant (the K20 Pro).

Update: They just changed their protocol to include preview image evaluation and trustability. I'm keeping the old table (for now) for reference purposes, and I'll be adding a new one as soon as they review at least a couple of new mclass-range cameras.

You can expect the same (or a bit bigger) deviation for high-end cameras, but anything with a score below 100-110 should be taken with a grain of salt.

This is valclass for all cameras tested with the previous protocol. For those that they dclassn't test, the deviation may be up to twice as much.



With regards to AMOLED screens, sometimes OEMs claim higher maximum brightness. That's because an AMOLED screen can push its brightness progressively higher as its white area gets smaller.

These values are from the lab tests made by GSMArena, and their white test pattern takes up 75% of the physical size of the screen.
