Xiaomi review Redmi 4 (4X). While other manufacturers are furiously trying to attract attention potential buyers With the help of super-powerful flagships, the Chinese company is not averse to expanding its range with budget models. Let's take a closer look at smartphones Xiaomi Redmi 4 and Xiaomi Redmi 4X, and let’s take a closer look at how these gadgets differ from each other.
Peculiarities
The release of new smartphones from Xiaomi is accompanied by quite a lot of excitement, since until a certain time the company's devices caused dubious sensations. The budget line, on the one hand, is not distinguished by powerful characteristics, but on the other hand, it attracts buyers with its price, and it is very attractive here.
Xiaomi Redmi 4 and 4X boast a 5-inch screen, a 13-megapixel camera with a powerful flash and the proprietary MIUI interface, but first things first.
Characteristics of Xiaomi Redmi 4 (4X)
It is quite difficult to evaluate the performance of budget smartphones, since all these devices are very similar in their hardware, and popular tests, such as AnTuTu, give almost the same results.
Both Redmi 4 smartphones have 8- nuclear processor Qualcomm Snapdragon 430 and 435 versions respectively.
Characteristics table
The maximum core frequency of the first is 1.2 GHz, the second - 1.4 GHz, but it is very difficult to reach these frequencies even with a fairly heavy load. Chips equipped GPU, which will allow you to play 3D games without stuttering, and also support LTE integration.
It is worth noting that the Snapdragon 435 will have a slightly less impact on battery life, as it has the Big.Little function - switching between sets of cores depending on the complexity of the tasks.
The manufacturer also decided to install 2 GB of RAM in the smartphones in the basic configuration, or 3 GB and 4 GB in the extended configuration. If we compare this indicator with flagship models, where 6 GB is boldly used, then this is not enough, but if we consider gadgets from Xiaomi within its price category- more than enough.
The battery capacity is 4100 mAh, which is budget smartphone quite good, especially considering that some gadgets are still equipped with 2500 mAh batteries. During active operation, one charge of the device will last for almost two days, and in idle mode the phone will last up to four.
But, it is worth noting that Xiaomi Redmi 4 still sits down a little faster, since a full set of cores will be used when performing tasks, and given that the processors are made using 28 nm technology, there is no point in talking about high levels of autonomy.
Appearance and Design
Both smartphones from the Xiaomi Redmi 4 line are relatively similar in terms of functionality, and the main differences between the models are in appearance. The non-index model measures 141.3 x 69.6 x 8.9 mm, with a weight of 156 g, while the 4X measures 139.24 x 69.96 x 8.65 mm.
Both smartphones have almost the same thickness and weight, but differ in height, and if these differences are quite small in terms of characteristics, then in real life the smartphones differ radically.
All elements take their place on the body - on the front side there is a display, touch control keys, a speaker, various sensors and front camera.
On the right, users will find the volume keys and the power button, on the left there is a SIM card slot, on the top there is a microphone for noise reduction, an infrared port and a headphone jack, and on the back there is a camera, a fingerprint scanner, and a flash.
Both gadgets have slight differences in the arrangement of elements, but they do not carry any functional load - purely design decisions. Despite the fact that Xiaomi Redmi 4 and 4X fit perfectly in the hand, the older model is still more comfortable, as it has rounded corners, while the younger one is a bit like a brick.
If we talk about color options, Redmi 4 is sold in:
- black
- gold
- silver
and here is Redmi 4X:
- pink
- black
- gold
and this means that the manufacturer expected to draw attention to this smartphone precisely from the beautiful half of humanity.
Display
If we talk about the screen of the devices, there are no complaints. The display resolution is 720 x 1280 pixels (HD) with dimensions of 5 inches, and the element itself is made using IPS technology, which provides viewing angles of up to 178 degrees without image distortion.
But with a vertical shift, the image will still change the contrast slightly, but users normal use This way the smartphone can’t be tilted, so this can’t be considered a minus.
The element itself is covered with protective Gorilla Glass rounded corners, but unfortunately, the manufacturer decided to leave its version under a veil of secrecy. In any case, the gadget will easily survive falls from a small height.
Camera and multimedia
In terms of cameras, the manufacturer also decided not to be sophisticated and equipped the Redmi 4 and 4X with 13 main 13-megapixel modules and 5 megapixel front ones. The quality of the images is quite good both in light and in dark time days, by the way, in the latter case, a bright flash will help users.
Gallery of photos from the camera
Camera features include autofocus, smile detection, dynamic lighting technology and panoramic shooting. The maximum resolution for video recording is 1080p at a frame rate of 30 FPS.
All videos and photos can be saved in the built-in memory, which can be 16, 32 or 64 GB, depending on the version of the gadget, or on external storage MicroSD format, with a maximum capacity of up to 128 GB.

Over six years of titanic work, the company has gained worldwide fame and can compete with Samsung and Apple, world-recognized companies, not to mention less famous rivals. Model range Xiaomi has expanded significantly in recent years due to the number of announced devices. Sometimes it’s not even clear how some Xiaomi smartphones differ from each other. Let's take a closer look at one of the representatives of the company's budget line - the Xiaomi Redmi 4X 32gb smartphone.
Unpacking and delivery contents
So, before us is a nice white box with the proud inscription 4X across the entire area of the lid. Having opened the package, we find the usual set for the device class: a smartphone, a paperclip for opening the SIM/microSD slot, a set of documentation with instructions for Xiaomi Redmi 4X 32Gb, a USB cable and a power supply.
Headphones are not included. We can talk about the controversial nature of this decision for a long time, although, if you think about it, it’s better to buy decent headphones yourself than to overpay for the dull cheap “tweeters” included in the kit.
Case design and materials
Unfortunately, the smartphone cannot boast of any new design solutions in the body design and appearance. Xiaomi Redmi 4X 32Gb, according to reviews, its appearance very reminiscent of the third generation Redmi line models. The design of the case itself and the quality of workmanship do not cause any complaints. The body of the gadget is metal, only the lower and upper ends of the device are made of plastic. All edges are neatly rounded and smoothly transition into 2.5D glass on the front panel. The device is very comfortable to hold in your hand. If desired, you can use Xiaomi Redmi 4X 32Gb with a case.
On the back panel of the device there is a fingerprint scanner and a main camera with flash. The scanner is conveniently located. If you take the phone in your hand, your index finger just hits the scanner window. The camera is located at the top edge of the body and, together with the LED flash, is shifted to the left edge.
On the side faces there are lock and volume buttons (on the right) and a slot for SIM cards and microSD (on the left). At the bottom end, in the center, between the identical speaker and microphone grilles, there is a USB connector.

Above the display are a speaker, a front camera, as well as light and proximity sensors.

Screen

The Xiaomi Redmi 4X 32Gb screen, according to reviews, produces rich colors, bright and pleasing to the eye. In strong sunlight, at maximum brightness, the image remains easily perceptible. Those who like to read in the dark are also not offended: at minimum brightness, information is perceived comfortably and the eyes do not strain. Avoids screen contamination. Fingerprints still remain, but are easily removed. For its price the screen is very decent. Some smartphone models at a higher price have a screen of worse quality.
Processor and performance
Mobile Xiaomi phone Redmi 4X 32Gb received an 8-core Shapdragon 435 processor and an Adreno 505 graphics accelerator. We must not forget that the smartphone belongs to the class of budget devices. You shouldn't expect any superpowers from him. Heavy games at maximum settings on the device will most likely not function properly. However, with average performance, the Xiaomi Redmi 4X 32Gb will run any modern gaming application.
According to synthetic tests, the hero of the review has very good performance and thanks to more modern processor looks more productive than the gadgets of its competitors, for example, the same Meizu company. The device left a pleasant impression. The performance of its processor is quite enough to perform any everyday tasks. Perhaps the device is not suitable for fans of serious mobile games, but it does not strive to be “ahead of the rest.” The device works out its price 100 percent.
Cameras
The main optical module of the device with a resolution of 13 megapixels, as expected after reading reviews of the Xiaomi Redmi 4X 32Gb, did not bring any surprises. In good lighting or in clear weather outside, photographs are obtained quite well. good quality. Naturally, as shooting conditions worsen, the quality of the resulting photographs also decreases. Nothing surprising for the camera of a budget-class gadget. The advantages of the camera include fast focusing and convenient application to work with optical module. The main camera allows you to shoot video with FullHD resolution. Frontal Xiaomi camera Redmi 4X 32Gb, in terms of characteristics, is ordinary, has a resolution of 5 megapixels and is no different from its competitors.
Wireless modules, navigation and communication
From wireless interfaces Xiaomi Redmi 4X 32Gb smartphone has Bluetooth 4.2 and Wi-Fi 802.11n. NFC, unfortunately, is not supported by the device. The wireless modules here are standard; no nuances were noticed when working with them. The device supports navigation using GPS, GLONASS and the Chinese BeiDou satellites. The device finds satellites very quickly and does not lose connection. Everything works at the highest level.
Among the features we can also note support for 4G (LTE) networks. The call quality is good, but the sound from the speaker may be slightly distorted. The MIUI application built into the shell allows you to record all calls.
Autonomy of the device
According to reviews, Xiaomi Redmi 4X 32Gb is fine with this parameter. I received the device very good battery with a capacity of 4100 mAh, which is a good indicator for a representative of the budget segment. Of course, the device did not set a record for autonomy, but in terms of operating time it showed itself to be a strong, worthy average.
At normal intensity of use mobile phone Xiaomi Redmi 4X 32Gb will easily last a day, and if you save a little, then even two. This result is possible, first of all, thanks to capacious battery, as well as screen resolution. Also, do not forget about the many energy-saving applications of Xiaomi's proprietary software shell - MIUI. However, with a “heavy” game, a smartphone can easily be used for 6-7 hours. With continuous video viewing, the device will last a little longer - about 13-15 hours. But considering that the device is positioned as a budget device, these figures can be called quite acceptable.
Gadget features unique to Xiaomi
The most main feature device, the pride of Xiaomi, is shell MIUI's own production. This firmware has many built-in useful applications. But there is also a small nuance. A person who has previously used a smartphone with a regular Android system will initially have a hard time understanding the MIUI shell. Menu items familiar to Android may be in the most unexpected places, or even completely absent.
The device also boasts an infrared port. Many are at first perplexed why this anachronism was even inserted into modern smartphone? In fact, this is a thoughtful marketing ploy. With the help special program MIUI shell and infrared port can turn your smartphone into a remote control for almost any TV or set-top box. An extremely interesting thing.
Separately, I would like to talk about the built-in program for controlling sound playback through headphones. You can select the type of headphones from a fairly extensive list, and also adjust the equalizer to give the sound the required frequencies. When played through headphones, the sound is very good and deep. Of course, a music lover with an ear for music may not like the sound, but the average user should like the sound.
And finally I will say...
There's not much to rant about here. Xiaomi has released another successful unit. And although it is practically no different from its predecessor except for design, somehow it has already managed to capture the hearts of users. Thanks to some low-budget characteristics, Xiaomi Redmi 4X 32Gb enjoys the well-deserved attention of a wide audience of users. The tempting price-quality ratio cannot be discounted.
The Xiaomi Redmi 4X 32Gb case (and there are plenty of accessories available for this device) will add a certain charm to the device. The device also has its own characteristics, which some users consider disadvantages. Not everyone will have a specific taste MIUI firmware. Someone will not want to buy a Chinese device, even if it is an excellent one, but for the same money will give preference to less productive devices from famous brands, for example, Samsung. There is nothing you can do about it, everyone has the right to their own opinion.
Appeared on Russian market in 2016, the Chinese manufacturer Xiaomi updated its line of smartphones in an affordable price category. The new model, belonging to the fourth generation, is called Xiaomi RedMi 4X.

The technical characteristics of the electronic components allow the Xiaomi smartphone to confidently perform in heavy games and cope with everyday tasks. In synthetic tests, the junior model produced the following results:
- AnTuTu Benchmark – 43200 points;
- GeekBench 4 – 2060 points in multi-core mode;
Communications
The smartphone works in cellular networks of all generations. Supported LTE frequencies, used Russian operators communications and VoLTE technology. The device has one radio module installed, so in voice communication Only one SIM card is active. An incoming call received during a conversation is not accepted by the second one, and the caller receives a notification that the subscriber is unavailable.
Options provided speed dial and automatic recording of a conversation with a subscriber.
The Bluetooth module operates according to the 4.2 standard, supporting Low Energy mode. To transmit data via Wi-Fi, a frequency of 2.4 GHz is used, according to 802.11 b/g/n standards. Fast networks The device does not support 5GHz.
For positioning on the ground, the smartphone can interact with the Russian GLONASS network, the Chinese Beidou and GPS.
There is no NFC chip in the device, therefore, despite the presence of a fingerprint sensor, Android Pay will not be available to users.
Display and cameras
The display of the smartphone is represented by a TFT matrix with a diagonal of 5 inches. Screen resolution is 1280x720, pixel density is 294 ppi. The display module is made using OGS technology, which eliminates the air gap between the matrix and the protective glass.
Color calibration is done well. According to the testing results, the color range is within the reference boundaries of the RGB triangle. The brightness reserve allows you to comfortably use the smartphone in direct sunlight. The display provides good viewing angles, with slight dimming of the far edge at maximum angles.
The device is equipped with two cameras. The front has a resolution of 5 megapixels, with a fixed focus, which is enough for taking selfies and transmitting high-quality images during a video call. The main camera has a 13 megapixel matrix with autofocus. Dynamic stabilization mode is not provided in both modules. The manual setting mode allows you to change only the white balance and adjust the light sensitivity. The aspect ratio is set to 3x4 or 16x9. The photo quality is adjusted by presets such as low, normal and high.
Video shooting can be performed in FullHD mode. The H.264 codec is responsible for image compression. The sound is written in AAC format. The lack of dynamic stabilization only affects the quality when shooting in motion. Video recording performed at rest is distortion-free, and the noise reduction system works satisfactorily.
Multimedia
The lack of headphones included in the package is compensated by the ability to customize the sound profile to the type selected for use with the device. The sound quality of musical compositions using the headset is satisfactory. Low and high tones are rich and clearly distinguishable. When playing tracks through the device speaker low frequencies are cut off and the sound turns out to be too loud. IN normal mode use when a speaker is needed to indicate incoming call, it's practically unnoticeable.
The smartphone can be used in FM radio mode. The role of the antenna is traditionally played by connected headphones. The voice recorder, due to its high-quality noise suppression system, allows you to record sounds both indoors and in open areas with good quality.
Playing movies using the built-in player revealed the absence of the AC3 audio codec. An audio track recorded in this format is not recognized by the smartphone. Video compressed with H.264 and 265 codecs is played without delays or lags. The standard codec for playing audio tracks is AAC.
operating system
Running Redmi 4X operating system Android 6.0.1. Marshmallow. Smartphones officially supplied to Russia have a global version of the MIUI 8 shell with pre-installed Google services. The interface is completely in Russian, the translation is done with high quality, without “blunders” and does not cause any complaints. Successfully combining the strengths of Google and Apple developments, it is considered one of the best for Android smartphones.
Xiaomi plans to further update the operating system used in Redmi 4X to version 7.1, bypassing Android 7.0.
Pros and cons
Comprehensive testing of the device and user reviews made it possible to determine its strengths and weaknesses. Let's start with the disadvantages:
- Contact list does not have quick search in Russian letters, the standard one is displayed on the right address book Latin
- Low vibration on silent call.
- Plastic overlays that stand out in tone in light models.
- Lack of NFC module.
- There is no backlighting of the touch control buttons.
As you can see, the shortcomings are not critical and relate to subjective perception.
Positives:
- High autonomy. The smartphone, in real use, lasts a whole day with a significant charge reserve.
- Fingerprint sensor operation. Recognition occurs quickly and without failures.
- Good ergonomics of controls.
- Ideal value for money.
Price range
In Russian retail, the junior model is in the price range from 7 to 8.5 thousand. Xiaomi Redmi 4X 32GB will cost 1 – 1.5 more. The price for the older model starts at 12 thousand rubles.
Conclusion
Concluding the review of the new Xiaomi product, I must say that the smartphone turned out to be really successful. For a low price, you can get high quality assembled device with good performance, even talking about the younger model. Older models are aimed at updating to the seventh version of Android and look even more promising.
