Apple iPhone 8 Plus vs iPhone X: 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 smartphone you should pick.

It has better glass protection and a better display. But the iPhone 8 Plus adds better battery life.

Anything else?

The iPhone X also comes with an AMOLED, larger (+0.3") display, better peak brightness, and a lightweight body (28 g./0.99 oz less).

How much more will the iPhone X cost me?

If you're considering a new and unlocked smartphone, it should be about $189 more expensive.

Is it still worth buying the iPhone 8 Plus in 2021?

The iPhone 8 Plus is still a great phone, even in 2021, especially now that it's cheaper. That doesn't mean you should ignore other devices like the iPhone 12 since it has better performance, better cameras, more security updates, faster charging, more RAM, and better display.

Is it worth getting the iPhone X in 2021?

The iPhone X continues to be a rock-solid smartphone because of its good camera. It holds up pretty well in 2021, but note that (again) the iPhone 12 features better performance, better cameras, more security updates, faster charging, and more RAM.

Just keep reading if you want to know everything about them, how they stack up against their rivals, and how the tech experts evaluate their specs.

In October of 2017, Apple launched its iPhone X. The iPhone 8 Plus, however, has seen the light of day 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 Plus and the iPhone X.

You'll rarely (if ever) find these two with the same price tag. Keep this in mind when comparing both iPhones.

For each featured section, there's a "Tek-Score" for you to check. We evaluated every quantifiable specification, so you can better understand the difference between the two. We'll also provide a global score for comparison if you're interested in other than these two.

The weight of each section

Our Tek-Score is based on a study done by Globalwebindex.com on what features users value on new smartphones. But you'll get a say in the matter by setting it to your personal preferences. You can go there right now, or just keep reading.

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

You're going to find a red or green bar next to some features. That can help you understand how they sit side by side with equivalently priced phones.

Here is their competitors' extensive list: but basically, we've excluded every smartphone that's not within a 20% (above or below) price range.

Feel free to click any feature title to check out several top 10 tables for all budgets.

Which One Has The Best Performance?

About performance: Geekbench 5 scores the iPhone X 2% ahead of its sibling in the multi-core ranking. All in all, there's not much of a difference between the two.

This isn't a performance contest because the two of them went for the same chipset: 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's display does stand out, and it should be noticeable.

The iPhone X features a 5.8" AMOLED display, while the iPhone 8 Plus has a smaller 5.5" LCD display. You'll likely have set your preferences already on the display type and size. AMOLED has perfect contrast and viewing angles, but its whites do hurt the battery life.

If you prefer a smartphone with a small display, there aren't many devices to consider besides the iPhone 8 Plus. At least it's short when compared to the average phone for its price range.

The iPhone X benefits from a higher resolution, at 1125x2436 pixels, while the iPhone 8 Plus has 1080x1920 pixels.

Just a tiny drop may shatter your phone, so I have to put this out: The iPhone X features a Corning toughened glass display. The iPhone 8 Plus has an Ion-strengthened glass.

There's no Always-On display feature here.

If you set these displays for auto-brightness, the iPhone 8 Plus will deliver 530 nits, while the iPhone X goes up to 726 nits.

Very few rivals share this maximum brightness. Usually, they max at 730 nits, but the iPhone 8 Plus can only go 200 nits below that.

Be aware that anything less than 500 nits just isn't suitable for HDR content nor to use in direct sunlight visibility. About HDR content: The iPhone X is capable of displaying HDR10 media.

Considering the iPhone 8 Plus, 97% of its rivals can play HDR content, 90% have an AMOLED screen, and 76% have an Always-On display. But only 24% of them have over 60hz of refresh rate.

For the iPhone X, please be aware that 89% of its rivals can play HDR content and have an Always-On display, and 94% have an AMOLED screen.

Which Phone Has The Best Cameras?

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

If you value quality photos, you should know that the iPhone X is about 22% above other competitors with comparable prices. Nevertheless, these two have similar scores, so...

Who's gonna win this battle? Apple's iPhone 8 Plus features a 12 Megapixels camera with an aperture of f/1.8, a 28mm wide-angle lens, four flash LEDs, HDR capabilities, and Optical Image Stabilization. It can record videos at up to 2160p.

The iPhone 8 Plus also packs a secondary camera with 12 Megapixels which has an f/2.8 aperture, plus a 57mm telephoto lens.

Its selfie camera features a 7 MP sensor with an f/2.2 aperture and a 32 mm lens.

This camera came out of DXOMARK's labs with a score of 104. Then, if you consider its telephoto lens, that will go up to 112**. You can check their review if you click here.

Last (but not least), you'd probably like to know that all of its rivals can record videos in 4K or more and have an ultra-wide-angle lens, and 76% feature Optical Image Stabilization. Yet, only 21% of them feature a macro lens.

As you're about to see, the iPhone X shares the iPhone 8 Plus camera setup. 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 the same 7 MP shooter with the same aperture of f/2.2 and the same 32 mm lens.

DXOMARK evaluated this camera, and here's the score: 109. By considering its telephoto lens, we'll get to the final score of 117** points. If you want to know more about it, check it here.

Finally, if you must know, all of its rivals can record videos in 4 or 8K, have an ultra-wide-angle lens, and feature Optical Image Stabilization. That said, only 11% of them feature a macro lens.

Something you will definitely enjoy on these cameras is their 2x optical zoom. This gives you an extra bit of freedom when taking your photos.

**Consider this as an estimative, particularly on mid-end cameras with less than 40MP and no zoom lens. They moved to a better camera test protocol, and there aren't enough reviewed phones to extrapolate a backward-compatible score.

Who has the best frame?

The iPhone X does have an advantage here, thanks to its weight and looks.

The iPhone 8 Plus has a height of 158 mm (6.23 inches) and a width of 78 mm (3.07 inches). Apple's iPhone X is a bit smaller, precisely 15 mm (0.59 inches), and a bit narrower too, about 8 mm (0.32 inches).

These two have about the same thickness: 7 mm (0.28 inches).

A front and back glass body does make these phones look premium on your hands. The iPhone 8 Plus is 28 g. (0.99 oz) heavier than the other, weighing about 174 g. (6.14 oz). But because screen size also matters, the "weight to display size" score of the iPhone 8 Plus is 0.7, which implies it's one of the heaviest phones for a 5.5 inches display. The iPhone X, however, has 4.5, so nothing to state here.

If you like having color options, you can buy the iPhone 8 Plus in Gold, Silver, Space Gray, and Red. The iPhone X, in its turn, comes in Space Gray and Silver.

If you like to keep your phones small, consider getting the Apple iPhone X. Otherwise, the other is the one.

Does a fingerprint scanner matter to you? Unfortunately, you can't count on the iPhone X, but if you're already considering the iPhone 8 Plus, then good for you.

You'll still get a second-best on the iPhone X. Wisely, Apple included a Face ID scanner.

The iPhone 8 Plus truly is water-resistant. It can be submerged 1 meter deep, and the same goes for the iPhone X. Remember that it shouldn't be for over half an hour, in standby and freshwater only, so no saltwater or pools here.

Which has the best battery?

In theory, they should have about the same battery life because they have the same capacity: about 2691 mAh. But as claimed by GSMArena, the winner is the iPhone 8 Plus.

If you charge it up, this is what you'll find out about the iPhone 8 Plus:

  • By talking for 1 hour, browsing the web for 1 hour, and playing videos for 1 hour, you'll have 79% of the battery remaining.
  • If you do 1 hour of talking, 3 hours of web browsing, and 1 hour of video playback, you'll get down to 63% left.
  • For 1 hour of talking, 1 hour of web browsing, and 3 hours of video playback, you'll still get 65% to spend doing other things.

And these are iPhone X's patterns:

  • After 1 hour of talking, 1 hour of web browsing, and 1 hour of video playback, you should have 76% of the battery left for the rest of the day.
  • After 1 hour of talking, 3 hours of web browsing, and 1 hour of video playback, you'll get down to 54% left.
  • By talking for 1 hour, browsing the web for 1 hour, and playing videos for 3 hours, you'll be with 60%.

Battery life on it still isn't anything to write home about. Apple didn't care that much about it. That's the conclusion that we take from its "battery to phone size" rate of 1.9.

Clearly, the iPhone X's battery capacity is well below the average in this price range. These numbers show that it is 11% below the rest.

If you thought charging speeds would help you pick one of these, they both do 15w.

Both phones support wireless charging at 5w.

Which has more storage?

None of them.

The iPhone 8 Plus comes equipped with 64GB of integrated storage and 3GB of RAM. Memory cards aren't welcome here. While it shouldn't be a deal-breaker, you should keep that in mind when purchasing one. Furthermore, other devices from this budget usually deliver more RAM and more storage. They average at 7GB of RAM and 124Gb of storage.

In its turn, the iPhone X features 64GB of storage and 3GB of RAM. There's also no expandable storage here. You may need a good data plan and some cloud storage. Again, you can get more storage and more RAM on most of its rivals. 8Gb of RAM and 142Gb of storage: that's the average, not the best you can find.

Storage shouldn't be an issue on any of these phones. However, if videos or big games are your thing, 64 GB will be a problem sooner than later.

Which is the most connectivity-friendly?

They also do have a resemblance here.

Both phones have Bluetooth 5.0, so nothing special here. As for the NFC chips, both have them.

There isn't much to say about the 3.5mm headphone jack, except that it simply isn't here. You can try an adapter if you want, but the wireless buds are the way to go here.

These two are LTE compatible. Do you want 5G on your next phone? Then, you should also consider the iPhone 12 Mini.

Which is more affordable?

The Apple iPhone 8 Plus isn't the cheapest smartphone that you can buy. But do search for any deals or price drops before making up your mind. The Apple iPhone X, on the other hand, is usually more costly, but I believe that it shouldn't come as a surprise at all.

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

If you're looking for old phones, I do hope you're considering second-hand here.

So, what about that global score? We'll get there. First, let me mention the average at their price range. They're in the ballpark of 6.5 for the iPhone 8 Plus and 6.8 for the iPhone X.

Verdict: What Makes the Apple iPhone X Stand Out?

The iPhone X is nothing but a redesign of the iPhone 8/plus. Of course, it's a remarkable redesign, and if you're indecisive about these two, you should try and go for the iPhone X. But let me make it clear that, while you get a better-looking phone (that actually is smaller but has a larger display), you'll lose on the battery department.

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.



As of now, these are the rivals that were considered for each of them. They may change every time its prices are updated.

Battery results

The battery score is based on Gsmarena's endurance rating and is taken with a screen brightness of 200 nits and a refresh rate of 60hz.

Assumptions: The display is off during a call, there's a web page refresh every 10 seconds, and the video playback is in Airplane mode.

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.
