What do we know about the Redmi line from Xiaomi? That it is budgetary, and therefore available to most buyers. And what do we know about the Note prefix in the name of the gadget? If we see it, then we are waiting for a large screen, which allows us to view the video in high quality and enjoy the games. It was all the more interesting to wait until the promised Xiaomi smartphone Redmi Note 4X. It happened in February 2017, and it's time to do full overview Xiaomi Redmi Note 4X.
Over the years, smartphone manufacturers have been constantly reworking budget segment releasing devices that offer superior design, excellent performance and a wide range of features, for the most reasonable and convenient for the price. Today we have two devices that represent this trend.
A device that has been used by many users due to its incredibly good price. 
Both devices have their own buttons located on the right side. Unfortunately, both of them also feel plasticity. Both are responsive and there were no problems in order to unlock the devices. But in terms of day-to-day performance, both are really good day-to-day drivers that can handle day to day tasks with ease.
Evaluating appearance Xiaomi Redmi Note 4x, it's hard not to notice how similar the device is to its predecessor - Xiaomi Redmi Note 4. The dimensions are completely identical, and the differences in design are minimal. For example, Note 4 had a metal back cover with a chamfer on the side, and Note 4x has plastic inserts at the bottom and top.
Changes also affected the color of the case. If the standard "four" was produced in three colors - gray, dark gray and gold, then the 4x became more original and is available in 5 color options. Among them, a black one appeared, which is very good. So now you can start looking for Xiaomi Note 4X Black. Well, if the black color is not to your liking, then you can choose gray, pink, blue or gold.
At first, he was able to handle the game with the highest setting, and only after a few seconds the device began to heat up as much as the drop in performance, so much so that the game became unplayable. Seems? Let's see. The picture taken with note 4 appears to have been reworked. It is also well optimized for performance.
You have a double click to wake up, access to all folders from another folder. It's like having a second phone that can have its own set of apps and other content. You can even set your own fingerprint.
In terms of ergonomics, there are almost no differences from the "four". The devices are pleasant to hold in the hand, and the only difference is in the barely perceptible greater tenacity of Redmi Note 4 due to sharp bevels. The location of the main connectors and mechanical elements on the case is quite familiar. Bottom Micro USB for charger, left and right speaker and main microphone. Headphones are inserted into the jack at the top, next to the infrared port and an additional microphone. On the left is a SIM card tray and a combined tray for a second SIM card or memory card. On the right is the volume and power controls. This is very convenient for right-handers, because the thumb goes directly to this area.
This would be very useful if, for example, you are allowing someone else to use your phone and you want some of your files or applications to be closed. It just depends on what kind or feeling is floating on your boat. 
With one unable to leave the other in the dust. Note 4 has a larger and brighter screen for media consumption. His rear camera also better in terms of overall quality.
On the back of the case we see a fingerprint scanner, just below the flash. It is standard on most Redmi models that have come out in recent years. Works great, recognizes data from multiple fingers.
Screen
Further in the review of Redmi Note 4X we will pay attention to the display. Its diagonal is 5.5 inches, the resolution is 1920 × 1080, that is, HD. On the surface protective glass creating a 2.5D effect. There is also an oleophobic coating, thanks to which fingerprints are easily and quickly removed. I would like to see less thick frames around the edges of the gadget, but forgive him this small minus.
It also has a more capable processor, at least in theory, although actual gaming performance suggests otherwise. It also gets too hot, which is almost uncomfortable for him. So what if I had to choose between these two? While he doesn't have big screen or better battery The processing package offers a better future. It is also more convenient to use on one side, and the sport is more premium in appearance.
But then again, it comes down to what your priorities are. At the end of March, the second was visited, and it was dedicated to today's review. Did the Chinese once again offer their customers a smartphone with excellent value for money? What are the differences between them or are they limited to names only? Performance, sound quality and performance are exactly the same. What surprised me the most was that the screen installed in it offers the best picture quality. The differences are also obvious when it comes to maximum brightness.
The picture on the screen does not lose color and contrast even in the bright sun, the information is easy to read. Judging by fairness and making allowances for the fact that we have a state employee in front of us, then 4 X looks very dignified. In terms of color gamut and temperature, the device is almost perfect. If desired, the user can easily manually adjust the settings - to make the screen warmer or colder. The screen recognizes up to 10 touches at a time.
The body of the smartphone is classic, rounded back. On the plus side, there are no protruding camera lenses. The finger is very nice. There are also problems with fast drawing. It's a shame the Chinese manufacturer hasn't decided on a different solution yet. The quality of the work is at the highest possible level, it is difficult to say about any bad word about it.
Luckily we have one manual mode... The front of the device is primarily a 5.5-inch screen in which we have three touch-sensitive function buttons: the last app, home screen and back panel. On the back, we see a 13mm camera with a camera and flashlight and a fingerprint scanner.
So all users will be satisfied, regardless of their personal preferences regarding the appearance of the screen and its properties.
Specifications
There are differences between the "four" and 4x also in the processors used. Redmi Note 4 had Qualcomm Snapdragon 625, and in 4x we already see MediaTek Helio X20. Synthetic tests confirm that the predecessor is inferior in performance to the heir by about 20% in all respects. This is natural, because MediaTek has 8 Cortex A53 cores and 2 more Cortex A72 cores, while the Snapdragon 625 has only 8 Cortex A53 cores. The two high-performance Cortex A72 cores make the difference.
In parallel, we will find a 3.5mm headphone jack, microphone and infrared port. Hybrid slot on the left side. Right volume and power buttons. In my opinion, this work surface is a reasonable compromise between the comfort of consuming content on the phone and the size of the device itself. At the moment, most models are equipped with such or even larger displays. Combined with a pixel density of 401 pixels, we can enjoy the picture with great sharpness.
Information about other important connection technologies supported by the device
However, the quality of the displayed image is equally important. Overall, as far as the medium shelf model is concerned, it is really very good. The viewing angles, decent blacks and pure white are also commendable. Outside on sunny days, very high brightness is very useful, although small "buts" appear as excessive reflections on the front glass. At night - Note 4 will also be tested. It reduces visual stress, which is really beneficial when used in the late hours.
This is not to say that the Redmi Note 4 with Qualcomm Snapdragon 625 did a poor job with everyday tasks or did not perform well in games even on decent settings. And no heating was observed there. It's just that 4x has become even more powerful, which is felt under any serious loads like using the latest games, etc.
In the end it was touching the sensory theme of touch. Here the review model was great and perfect for writing emails, news or more long texts. Touch buttons under the screen they reacted without reservations. Web browsing, gaming, video playback, photo editing and then some - this phone is more than capable of it. If you could fill the memory of your smartphone, there will only be one, what would it be? Would you choose a collection of your photos or a whole bunch of modern apps, could you get rid of all your music to make room for videos?
Note that MediaTek processor Helio X20 comes with 4GB random access memory and 64 GB built-in. Xiaomi Redmi Note 4X deserves the status of a prime bundle. There is also an alternative less powerful option - Xiaomi Redmi Note 4X 32gb. As you might guess, the built-in memory is 32 GB, and the RAM is also less than in the previous case - 3 GB. The processor is exactly the same as in the standard Xiaomi four - Qualcomm Snapdragon 625. Considering that in the second version of the declared 32 GB the user can actually load 22 GB, it makes sense to buy this option only if you do not plan to install a second SIM card and want to get SD memory card.
Colorful metal body design and extended battery life
He treats the metal in the colors of champagne gold, platinum silver, cherry powder, matte black and exclusive ocean aquamarine, which was inspired by Hatsune Miku - the sound of the future. Basically, we think that with everything else, choosing the color of your smartphone won't be that difficult. Try to choose between these 5 awesome colors.
It is suitable for people with more sophisticated tastes. Silver silver. It is neutral, it is orderly and it gives the feeling that it is part of a modern city. Matte black. It is timeless and minimalistic, and expresses restraint and wisdom. Black has a strong impact compared to what something mystical can do.
- Such a soft and soothing color.
- Feels like it can really handle your stress.
- Champagne gold.
- He represents optimism and lofty ideas.
With the help of an infrared port, the device provides easy interaction with any "smart" technology in the house. Wi-Fi internet connection is reliable, supported up to 5 GHz. Searching for a satellite is very fast, even if the Internet is disconnected.
This will give you 22 hours of reading, 18 hours of video watching, and 15 hours of gaming. It is an exceptionally bright display with 450nm brightness. Wide color gamut of 72% allows colors to be displayed much closer to what they are in real life so as not to conflict with your perception of natural colors. For your eyes, the display can adjust color temperature, reduce brightness, and reduce blue light.
Read as much as you like without hurting your eyes. Combine that with phase detection autofocus and 17 real-time filters and you can see why it is not only ahead of its competitors, but ahead of its time. Each of your photographs becomes a masterpiece. You never know if taking a photo is enough. When you're in the middle of a festival, you probably want to have live footage.
There are no problems with the spoken speaker, as well as with the microphone. Communication on this gadget only causes positive emotions... True, the multimedia speaker sometimes wheezes at maximum volume. Therefore, we recommend using headphones - there is no such problem with them.
The software is based on wrapped in MIUI shell 8.2 platform Android 6.0.1. Thanks to the stable global firmware you can use phones in different languages, including Russian. A lot has already been said about the possibilities to customize MIUI 8.2 for numerous parameters that are convenient for the user. Let's just note that the platform is really convenient, and it is great to use such a phone both in everyday communication and for solving more complex business problems.
Performance, heating, power consumption
The biggest surprise is the dual-device mode. Use different unlock gestures to access different photos, apps and games. Fixed lock screen, remote control, double-opening apps will hit all the chords you need.
Submit emails, play online games, order food or call a taxi faster! Over the past 3 years, more than 110 million smartphones have spread around the world, reaching everyone who wants a reliable device to be done without problems every day. High tech is closer than you think.
Camera
The main camera of Xiaomi Redmi Note 4X has 13 megapixels and an f / 2.0 aperture. Mostly these gadgets are completed Sony modules imx258 and have PDAF phase detection autofocus.
If you are using a stable official firmware, you will be able to record video in Full format HD. But we already know that in the firmware for developers, the manufacturer has gone even further, making 4K recording possible. The camera interface is clear and simple, although there are enough settings for demanding users.
As for the camera, performance and functions. You have to restart your phone though to get rid of the frozen operation. My money just went to flicker. Which ones are the most stable in performance and battery consumption? Screen resolution, sound quality, camera worst of all. Although both smartphones target different consumers, they are still competing for similar prices. We cannot rate any of the display panels over the other because it is difficult to notice any difference with the naked eye.
Both displays look crisp and evenly saturated. Viewing angles are decent, and outdoor visibility is not a problem either. In the dedicated wide aperture mode, you can take a photo with variable aperture for various bokeh effects, which can also be adjusted later.
In practice, the pictures taken with this unit are of good quality, adequate white balance and acceptable color reproduction. Of course, you can find better cameras from the flagships, but for budget smartphone everything is more than great.
While in low light, both cameras took similar pictures. Honestly, software is something that depends on your personal taste. Other than that, both smartphones have fingerprint sensors that work very well.
A mobile network is a radio system that allows multiple mobile devices to communicate with each other.
The German language will follow, which always takes a few days to come out. This is not the case from your side. Is this device also in German version, or can the device be played in German? Yours sincerely, Egon Hein. Answer: There is German Rome, but this can only be installed by the client because you cannot handle the bootloader. Always talk about multi - Rome or international Rome, what does Rome really mean? There probably is new method but it hasn't been verified by us yet. If we tested it and it works, we will offer it with a multi-rum. With the silver and gray versions, this is definitely not the case, but the body is completely made of aluminum.
- Can you get rid of the duo language?
- Answer: Of course, no problem.
- Is this a pro, or a normal 4?
As for the front camera, it also received an f / 2.0 aperture, and a module from another company is already used here - Samsung S5K5E8. By the number of pixels, everything is familiar - 5 megapixels. As in previous versions, there are no complaints about the camera's operation, but using it in low light conditions is impossible without harm to the quality of pictures or video.
Autonomy
The battery of the 4x is exactly the same as that of the Xiaomi Redmi 4. Its capacity is 4100 mAh. According to the manufacturer, the gadget can easily withstand 18 hours of video viewing in a row without the need for recharging. In fact, the figure is slightly overestimated, but if you want to watch your favorite TV series, and you decide to check the words of the Chinese with reality, then you should count on something on the order of 11-12 hours of continuous work. In the PC Mark test mode with a brightness parameter of 44% (200 cd / m2), the smartphone withstood a little over 11 hours.
If your plans include using the phone only for everyday purposes without prolonged games and watching videos, then the charge will be enough for about two days. During the night, the percentage of the charge decreases by only 2-3%.
Everything seems to be pretty decent and good, but still lacks a function fast charging... When you have used up the entire energy supply, you will have to spend more than three hours to replenish it. The device is charged through a 5V 2A power supply.
conclusions
Have Xiaomi developers offered us something radically new? More likely no than yes. Compared to the Redmi Note 4, the X version has a minimal improvement in performance and only cosmetic design changes. Nevertheless, we give the manufacturer a big plus for trying to improve an already good gadget that is becoming more and more popular on the market. If you buy the prime version of the 4X, you will be able to load the device more in comparison with the standard "four", and this will appeal to gamers and those whose work is connected with the active use of the smartphone.
Buy Redmi Note 4X is definitely worth it for lovers of economical gadgets with big screen and good autonomy. The difference in the quality of a smartphone in comparison with the "four" is not so great, but the price is not much higher. Because if you already have Redmi Not 4, then there is no point in changing it to 4X, but if you choose between models, then feel free to take Redmi Note 4X and you are guaranteed to be satisfied!
Xiaomi Corporation in January this year in the technological capital of India officially presented new smartphone, which can rightfully be considered one of the breakthroughs of 2017. The well-known Chinese concern has made a major breakthrough for the last few years thanks to the excellent design of its smartphones - smartphones have quite serious advantages - an ergonomic appearance, the presence of all new products of interest to the consumer and potential brand development prospects make Xiaomi one of the authoritative leaders of this market segment. Potential consumers are interested in the question in detail - how serious are the technological differences between the two leading gadgets Xiaomi Note 4 and XIaomi Note 4X
Appearance and ergonomics of gadgets
Both smartphones offered to the consumer entered the market within a short period of time, therefore, the appearance of both gadgets has not undergone particularly big changes - a familiar rectangle that combines a noble aluminum shine and plastic inserts on the sides. The gadget is available in several color textures at once - the now popular pink, as well as gold, which makes the gadget very aristocratic in appearance. The fingerprint scanner is on the back, it works quite decently, but with dirty hands on the back, unpleasant fingerprints will undoubtedly remain. Otherwise, the look of the smartphone is quite typical - the home buttons on the panel, the frames visible on the sides of the gadget, which makes the gadget something similar to Apple products. The front surface is covered with durable toughened rounded glass, giving the grip sufficient strength. The new sample is still a bit thinner, down to 8.35 mm, which is difficult to determine without special skills. Otherwise, the dimensions of the smartphone remained the same.
"The heart of the smartphone"
Different processors are responsible for the performance of both gadgets - this is what most experts consider the most important difference between gadgets. In the model, which was released in August 2016, the manufacturers decided in favor of the MTK processor - 4 cores with a capacity of 1.9 MHz. In recent years, it has become increasingly popular among Asian consumers Qualcomm processor Snapdragon 625. Of course, given processor does not have the power of its fellows, but is great for mobile devices middle price range. In addition, the power of the cores has increased to a truly fantastic 2.3 MHz instead of 1.9 in the previous model. The change of the processor is due to the specifics of the region where the smartphones were supplied, but in general, according to experts, this practically did not give a significant increase in performance. New model Xiaomi Redmi Note 4X received an increased amount of RAM.
Camera
Here, both gadgets have the same indicator - 1920 by 1080. This is quite enough for colorful filming. If desired, it is possible to enable HDR mode- the luminosity will improve slightly. Note 4 and Note 4X are equipped with 13MP camera and 5MP front camera with improved balance when shooting on the move. In the dark, there is still a lot of noise - Chinese engineers have room to grow, and the matrix, in general, is rather cold for gadgets.
