As you can see, both devices have significant differences regarding their display, battery, camera, and processor speed, among others. The iPhone 13’s redesign, while it is not huge, can surely make a difference when you hold it. Let’s see everything in detail, shall we?


The screen is one of the fundamental aspects of an iPhone and any device. It’s the element we are always in contact with. Therefore, manufactures and users alike are very demanding in terms of the quality of the smartphone’s screens.

The first thing worth mentioning about the iPhone 13 is that its screen is larger than the iPhone X’s. While the latter has a 5.8-inch screen, the former has a 6.1-inch screen. But, not everything is about size. The evolution of the iPhone 13’s screen is also remarkable concerning brightness.

The screen of the iPhone X is a Super Retina HD, while that of the iPhone 13 is a Super Retina XDR, both with OLED technology. The maximum brightness reaches only 625 nits in the X model, while in the 13, it goes up to 800 nits or even 1200 nits with HDR content. Both feature True Tone technology and a wide color gamut. Finally, it is worth mentioning that the resolution has also improved, although slightly in this case.


The design is the most noticeable change between one device and the other. As we mentioned before, the iPhone X was the model that undoubtedly introduced the most changes since the first iPhone. And this is not only regarding the design; it also implied a new way of using your device through different gestures. iPhone 13 inherited the renewed design that occurred with the iPhone 12 generation.

iPhone X and iPhone 13’s appearance may look similar, but the latter has more squared edges. This indeed reminds us of the old iPhone 4 and 5 models that made users fall in love the first time. Even if it seems like a minimal redesign—and it can be—, it completely changes your feeling when holding the phone in your hand.

In addition, the notch is now 20% smaller. The functionality is still identical; you can expect the same great TrueDepth camera system and Face ID. The notch, however smaller, may still be a distraction for some users who use white background apps in portrait orientation, such as Gmail. At the same time, the power button, the ringer switch, and the volume buttons are placed slightly lower compared to the iPhone X.


The iPhone cameras have been the best of the best throughout the years, and the iPhone 13 does not break with tradition. About the rear camera, The iPhone X has a wide-angle lens with f/1.8 aperture and a telephoto lens with f/2.4 aperture. On the other hand, the iPhone 13 keeps the wide-angle lens, improving the aperture to an f/1.6 and changing the telephoto lens to an ultra-wide-angle lens with an f/2.4 aperture.

On the front, you can also find significant differences between the two devices. First, the iPhone X has a TrueDepth camera with an f/2.2 aperture and 7 Mpx, similar to that of the iPhone XS. The iPhone 13 also offers a TrueDepth camera with the same aperture but raises the number of megapixels to 12.

The improvement in terms of photography and video lies in the lenses of the devices and the chips. The iPhone X has the A11 Bionic chip, while the iPhone 13 enjoys the A15 Bionic, an evolution that, without any doubt, makes the difference. With the iPhone 13, you can also enjoy features like Night mode, Deep Fusion, and the Apple ProRAW functionality—the latter only found in Pro and Max versions.


The base storage for the iPhone X is 64B, while the iPhone 13 comes with 128GB. Both the iPhone 13 and iPhone X have versions with 256GB of storage. However, only the iPhone 13 has a top-end variant with 512GB—and the Pro and Pro Max variants have up to an impressive 1TB of storage.

As for the RAM, the most significant advantage the iPhone 13 does have is its 4GB, while the iPhone X shipped with 3GB. The additional gig of RAM means the iPhone 13 is much better at multitasking than the iPhone X.


The A15 Bionic chip of the iPhone 13 is capable of performing much better than the A11 Bionic chip of the iPhone X. The new processor is ahead of the A11 chip, which only has a two-core neural engine, while the A15 has a 16-core neural engine.

Apple has always been able to perfectly optimize the performance of their iPhones and devices in general, which is one of their strengths as a company. However, the differences between the two of them won’t be that noticeable for users who make more or less normal use of it.

Battery Life & Charging

Ah, the battery. That is the neverending worry of a smartphone user and, obviously, of an iPhone. The battery life of an iPhone has been called into question multiple times. Now, Apple has been trying to improve the autonomy of its new devices. For the iPhone 13, this means a considerable improvement, even so considering the size of 6.1 inches.

If we look at official data, we see how video playback on the iPhone X can reach up to 13 hours, while on the iPhone 13, it increases to 19 hours. The same goes for video playback, which in the X model reaches up to 60 hours while in the 13, it increases to 75 hours. These numbers are quite considerable, and if you want the best of the best in terms of battery, iPhone 13 Pro Max is the king of the hill.

About charging, iPhone X has a Lightning port and the possibility of using wireless charging features that the iPhone 13 also has. The newest model adds one more alternative: charging the device with MagSafe technology and its compatible accessories. In any case, both models enjoy fast charging and can charge up to 50% of the battery in just 30 minutes using a 20W or higher power adapter.


All iPhone 13 models include 5G connectivity, while the iPhone X doesn’t. It might not be something to consider shortly after the iPhone 13 release since the 5G network is not fully developed yet, especially in some countries. Still, it will be important in the future.

It is also worth mentioning that the iPhone 13 is equipped with the Apple-designed U1 chip that has Ultra Wideband availability. It supports AirTags tracking, which allows you to track personal items with an iPhone or other Apple devices.
