Review Apple iPhone X 25


On the occasion of the tenth anniversary since the first iPhone was introduced by Steve Jobs, Apple It has launched a special edition of this famous smartphone in addition to the iPhone 8 and iPhone 8 Plus, with a design never seen before that impressed many during its official presentation in September 2017.

Today we bring you a complete analysis of the new iPhone X, which stands out for incorporating for the first time a 5.8-inch OLED type screen, which is accompanied by HDR10 and Dolby Vision technologies, in addition to its True Tone function, and that covers virtually the entire front of the equipment. In addition, the Touch ID is left behind to give way to Face ID, a 3D facial recognition system that works even at night, technology that also makes the famous Animojis work.


All of the above is enhanced by the powerful processor Apple A11 Bionic, neural processor and an integrated M11 motion coprocessor, in addition to carrying 3GB of RAM and its storage varies between 64 and 256GB. Everything is controlled by the iOS 11 operating system and powered by its 2716 mAh battery capacity. In addition, we now have a design built of glass and a double main camera of 12 megapixels with new functions that is capable of recording in 4K with up to 60 frames per second.

This complete review comes to you thanks to the kindness of our great friends of ProMovil who provided us with this unit and thus tell you all the good and the bad of the current flagship of Apple.

At last we have new design! After almost 4 years using the same iPhone 6 design finally Apple opens a new iPhone and has a design that many love, including this humble editor.

Review Apple iPhone X 26

It is that finally we will no longer have to look with envy eyes at the beautiful designs of Android devices, Apple It finally catches up with this design where we see a 5.8-inch screen cover practically the entire front of the equipment, eliminating forever those thick edges that accompanied us these years.

Without lying dear reader, everyone who saw the team said that the design and its screen were the best and I totally agree with them. It is an iPhone with a larger screen than the Plus model, but with a size almost identical to that of the normal model (the 4.7 ″), which makes the device very comfortable to hold, carry and control.

Review Apple iPhone X 27

To this design we also add the glass in the back as we saw in the iPhone 8 and its Plus model, which also makes the team a little heavier reaching 174 grams. On the edges we leave behind the aluminum and use stainless steel. We also maintain the IP67 certification that certifies its resistance to water and dust. Its dimensions are 143.6 x 70.9 x 7.7 mm.

And where is the Touch ID?

It was simply removed and replaced by a 3D facial recognition system called Face ID. That is why we see a bar at the top of the screen, since there is not only the headset and one of the speakers, there are also all the necessary sensors to perform 3D facial recognition, in addition to the front camera.


Here we have one of the “best screens ever created”, that was what the experts of DisplayMate mentioned when they had to evaluate the image quality of this OLED Super Retina type screen that reaches 5.8 inches, offers a resolution of 2436 x 1125, a 19.5: 9 aspect, a density of 458 pixels per inch and a contrast ratio of 1,000,000: 1. It also has the ability to play content on HDR10 and Dolby Vision.

Review Apple iPhone X 28

As expected of an OLED screen, the image quality of this screen is very good and has a very high level of brightness and luminosity, which in turn makes the colors look vivid and with an excellent definition in the image.

When I learned the iPhone X would have an OLED screen, I thought I would find a quality similar to what I saw on the Samsung screen Galaxy S8 or Note 8, but the truth is that it was not so, because on the iPhone X I found natural and vivid colors, but I did not find very saturated colors as it happens in Samsung's Super AMOLED screens, which I liked. It is a quality a little higher than the IPS LCD, but here you have the same deep blacks of the AMOLED.

Review Apple iPhone X 29

As we saw in the iPhone 8 and 8 Plus, here we will find a new option called True Tone, which thanks to a sensor that is incorporated, the iPhone will be able to match the hue of the screen according to the light condition in The one we will meet. We also continue to maintain the 3D Touch obviously.

Review Apple iPhone X 30

✅ New design at last! ✅ Elegant, futuristic, eye-catching design✅ You are finally saying goodbye to the giant edges on the screen✅ OLED screen✅ Screen quality, good definition, vivid, real and non-saturating colors✅ Compatible screen with HDR10 and Dolby Vision technologies✅ Very comfortable to use design, it has a rather “standard” size

❌ It gives you the feeling that at any time you will fall and break, forcing you to buy a protective case to be quieter


Review Apple iPhone X 31

In this section I will talk about the double camera that we will find in the back of the device, and that unlike what we see in the iPhone 8 Plus, here we will see a double vertical camera. Both sensors are 12 megapixels, one of them has an aperture f / 1.8, size 28mm, while the second sensor has a size of 57mm and an aperture of f / 2.4. Both cameras have OIS optical stabilization.

While on the front we will find a 7 megapixel camera that will be the one that will take our selfies and that on the iPhone X can be captured in Portrait Mode or make video calls. Its sensor has an aperture f / 2.2 and 32mm.

Review Apple iPhone X 32


The camera app used by the iPhone is one of the easiest to use because it offers somewhat basic options when compared to other Android device interfaces. For example, here we will not find a complete manual mode, but we can control the exposure manually or block the focus at X point.

Review Apple iPhone X 33

We will have 7 modes to use the iPhone camera: Photo, Portrait, Video, Square, Panoramic, Slow motion and Fast camera. If we select the Photo mode, we will have at our disposal up to 10 filters to apply to our photographs, in addition to being able to use a timer, control the LED flash and activate the Live Photos function, which will allow us to capture an image and which in turn captures a couple of seconds of video and audio of the moment.

Review Apple iPhone X 34

If we select the Portrait mode, we will have 5 capture modes: Natural light, Photo studio light, Contour light, Reflector and Reflector B and N. The good thing about these capture modes is that if you take a picture with the "Reflector" mode , but then you regret it and want to select another mode, just choose the “Edit” option and we can switch between the 5 available modes, without the need to take the picture again, since the capture data is saved in the file final. All of the above can also be used with the front camera for your selfies.

In the following image gallery you will see the results of each of the 5 modes mentioned above:

In the following demo video you will be able to know the rest of the iPhone X camera application interface, as well as appreciate how the 2x optical zoom and 10x digital zoom works:


In this section I will leave you with some photographs that were captured directly with the iPhone X, in different light conditions and with automatic settings:


Our protagonist has the ability to record videos in 4K quality, but unlike the rest of his competition, here we can record in 4K with up to 60 frames per second, as well as we can do it in 30 frames and 24 frames. We can also record in Full HD in 60 and 30 frames per second.

For this reason I will leave you with four test videos that were recorded in 4 different qualities so you can appreciate. I remind you that YouTube Decrease the original quality of the video.

4K 60fps video

4K 30fps video

4K 24fps video

60fps Full HD Video

✅ Very good photographic quality ✅ Very good video quality ✅ Portrait mode sometimes has its small flaws like everyone else, but the results are very good ✅ The best optical stabilization I've seen at the moment on a smartphone ✅ Camera app is very Easy to use

❌ A manual mode is missing to get more out of this camera


Our iPhone X comes from the factory with the iOS 11 operating system, but when you start it and connect it to the internet, we will be updated to iOS 11.1.2 which is the stable version of the moment. Here everything runs 100% fluid, there is no word slow or lag, and this is not only due to how well the operating system is optimized, it is also because the team is using one of the most powerful processors of the moment, the Apple A11 Bionic and leading the ranking of benchmarks.

Review Apple iPhone X 35

iOS is an operating system that is very easy to use, but what stands out is its stability and optimization. In fact the applications are also better developed and the catalog of apps is practically the same as you find on Android, for example.

Here we will also find a shortcut bar to main functions, such as to activate Wi-Fi, Bluetooth, mobile data, multimedia control, brightness, volume … etc, as well as a received notification bar and a section to have our widgets.

Review Apple iPhone X 36


Since we don't have a start button now, you will most likely wonder how we will return to the start, how we unlock the iPhone, how we access multitasking … etc. Well, all of the above was replaced by gestures that are very easy to learn and you will see that in just a couple of minutes you will be fully accustomed, including if you come from a previous iPhone version.

Pay attention to the following video:


Having no start button, we will not have the Touch ID security method. Thus, Apple implemented Face ID, a 3D facial recognition system that will prevent us from using our fingerprint to unlock our iPhone.

Review Apple iPhone X 37

You can use it day or night, with or without glasses, with a hat or without a hat, in the same way it will be able to recognize your face without problems. And if you are sleeping, Face ID will not work, since apart from scanning your face, it will also check if you are awake or not in case someone tries to access the iPhone while you are sleeping.

In the following video you can see how is the process to register your face in Face ID:

And in this video I will show you a large part of the iOS environment and how it runs, so that you can get an idea of ​​what you will see when you buy the device:


Being the first iPhone to use this image format, there were virtually no applications compatible with this type of appearance. However, today most have already been updated and take up all the screen space, such as Netflix, YouTube, Twitter, Facebook, Telegram, WhatsApp, Spotify … among many others.

Review Apple iPhone X 38

However, what about those that have not been updated? The application works in the same way and with total normality, only that it is seen in the 16: 9 aspect of the previous versions of the iPhone, leaving large black spaces on the screen.

Review Apple iPhone X 39


Review Apple iPhone X 40

We are facing a new fashion that has been implemented in the iPhone X and is breaking it on social networks. It takes more advantage of the sensors that capture your face in a 3D way – used by Face ID – because thanks to this data you can use emojis and animate them according to what you are doing with your face. You can record all this on video and then share it on social networks or by iMessage.

Review Apple iPhone X 41


In this section our protagonist has a battery of 2716 mAh capacity and as a novelty brings compatibility with wireless charging using the Qi standard, which allows it to be used with most of the wireless chargers existing in the market. It is also compatible with fast charging – charger sold separately – and not only compatible with chargers Apple, also works with third-party chargers that use the standard USB Power Delivery (USB-PD).

Of course we have tested the autonomy of the battery of the equipment and according to my own experience, it lasts almost equal to what the iPhone 8 Plus offers. However, here I will leave you the detail of the test.

Let's go with the detail:

Used applications: Face ID, Twitter, Facebook, Messenger, Safari, YouTube, WhatsApp, Telegram, BBM, Google, Roku, Instagram, Swarm, Buffer, TuneIn Radio, Maps, Music … among others.

Wearables connected: Apple Watch (first generation)

Active connectivity: Wi-Fi, 3G / 4G / 4G +, Bluetooth and GPS (occasionally)

Brightness of the screen: Automatic

As described above, the iPhone X gave us an autonomy of approximately 27 hours.

Review Apple iPhone X 42

✅ Excellent operating system performance muy Very easy to use interface operativo Operating system is kept updated directly with Apple, without depending on location and / or operator✅ Face ID works very well✅ You easily get used to gestures instead of the start button✅ Several applications have already been updated to take advantage of the 19.5: 9 aspect of the screen

❌ Personalization level is not as complete as in Android❌ Many people will miss the Touch ID and will not easily get used to Face ID❌ I feel that iOS 11 still does not take advantage of the 19.5: 9 screen, as it is currently being forced and not taking advantage of the extra space he earns. Maybe with iOS 12 the thing changes.


One of the things that highlight the products of Apple It is precisely in audio and multimedia, and in the iPhone X they demonstrate it very well thanks to its functions, features and applications that I will detail below,


This time we have the app Music as the protagonist where we can listen to all our songs that we have stored on the device, in addition to being able to access the payment service Apple Music that will also give us access to the library we have in iCloud.

Review Apple iPhone X 43

Outside the Music application and within the configuration menu we can access an equalizer to further improve the sound quality, with up to 23 pre-equalized profiles. You can also control the maximum volume power to your liking in case it is very high or activate the automatic volume control.

Review Apple iPhone X 44


Here we do not have an independent video player, since as with Android, our videos will have to be viewed through the Photos application to take advantage of OLED technology. Now, there is the Videos application, but it only serves to view content purchased from the iTunes Store.

Review Apple iPhone X 45


We arrived at one of the points that I liked most about the iPhone X, since the audio that one obtains in this equipment is quite good, with powerful bass and treble, and a well-known definition, in addition to offering a high power in volume, It is not limited by software as it happens in some Android devices.

The latter could be verified with the wired headphones that the factory equipment called EarPods incorporates that are connected directly to the Lightning port of the equipment. The same experience I also got with the Bluetooth headphones that we know as AirPods.


In this iPhone we have two speakers, one located at the bottom of the device and the second is in the space for the headset, thus giving full stereo sound. Of course, unlike others smartphones In the market, the speaker where the headset is is a true speaker and is not a small headset that is forced and delivers high-pitched sound.

Review Apple iPhone X 46

Here we have two powerful speakers that sound quite loud, and I would say that they sound a little louder than the stereo speakers that the iPhone 7 Plus incorporates and exactly the same as the iPhone 8 Plus speakers. They also impress the bass levels they reach, making a large part of the team rumble. However, the sound quality is excellent, it's nice to listen to music on them or watch videos, movies and play.

✅ Music player is quite complete and easy to use ✅ Excellent sound quality through wired and wireless headphones volumen Volume power is NOT limited by software ✅ Excellent quality stereo speakers and powerful in volume

❌ Pretty poor video player❌ While no iPhone has had FM Radio, it's never too late to implement it


As you may have noticed, I liked the iPhone X quite personally. But far what I liked the most was his design change, because in the end we have an iPhone that is different and that will no longer go unnoticed by carrying the same design from the previous version. And is that seeing that OLED screen with vivid and real colors that occupy practically the entire front of the screen, is a real luxury.

The rest of the team is also excellent, both in its performance and in its double camera, since the Portrait Mode works excellent in its rear and front camera, and the optical stabilization of the videos works very well. I liked the audio of the equipment, as well as its autonomy.

Review Apple iPhone X 47

Whatever iPhone you have, I recommend you buy the iPhone X, it is a great change that you will notice, it is from another generation. I would improve a little design because I always feel that I will fall and then break the glass, so I recommend that you buy a protective case for added security.

If you are bored of the slowness, poorly optimized applications or that your manufacturer is delayed or does not update your device, with the iPhone X I assure you that you will have excellent performance and you will have updates when everyone else also receives it.


The iPhone X can already be yours right now if you buy it with our friends from ProMovil, where you will find it in 64 and 256GB versions. Chile arrives officially from December 7 in the main operators and retail stores.

We thank the friends of ProMovil who lent us this iPhone X to have you new complete review.
