Components

His redmi Note 3 company Xiaomi packed in very different than had the previous model, a box. It is no longer framed in a dirty-brown tones utilitarian appearance, like oiled wrapping paper – it is now more familiar, white with colorful pictures and logos of a small cardboard box. It’s hard to say, it became interesting look such packaging or worse, but it markedly decreased in size – it is a fact

Set as usual, is not rich, it consists only of a miniature battery charger with an output current of 5 V 2 A. and connecting cable Micro-USB. Metal key to extract SIM-card habitually attached to the paper tab.



appearance and easy to use

The shape, size and overall design Redmi Note 3 repeats its predecessor Redmi Note 2. This all the same streamlined on all sides “trough” with rounded edges and heavily rounded in terms of angles, glued to the flat without bumps and skirting display glass

changed. materials: a large part of the body is now made of aluminum, but the side insert the ends of all of the same plastic. In these plastic and metal segments not all hull cut holes microphones and connectors, it protects the plastic at the corners of bumps and dips. Housing Xiaomi Redmi Note 3, thus, can not be called an all-metal, but metal housings arranged most of today’s mobile devices. These inserts are necessary in order that the metal is not shielded antenna communication modules, although some manufacturers have found another way out, putting them into the outer grooves, filled with plastic (to do so, for example, Apple).

Because of the emergence of metal body redmi Note 3 did not become substantially more difficult: the mass of new items only 4 grams of weight more than the previous model redmi Note 2. But what matte metal slides in the hands much stronger than plastic, it is a fact. Updated Redmi Note in the third incarnation became stronger, but also more slippery. Perhaps users will have to cover this most metal plastic or other cover, so that’s ironic

About the size of say anything already useless. Yes, 5.5-inch-polusmartfon poluplanshet – is in any case a very large to be held in a human hand thing. It is quite inconvenient to manipulate with your fingers of one hand, but humanity has managed to get used to it and carefully pretends not to notice the inconvenience, and it finally freed the hands producers.

All items featured on housing trends, their shape, size and location is almost exactly repeated predecessor, except for appearing of new parts – a fingerprint scanner. Chinese Apple quickly picked up the idea about the authorization of this useful tool, but, as usual, could not anything not to spoil. So, all for some reason began to place the scanner on the back side of the case, although it is obvious that it is more useful on the front panel. For the “back” from the scanner lying on a table or standing on the base unit is not available, and in the car holder to grope him “somewhere” is quite uncomfortable. And here, for example, the developers of Samsung and Sony was smart enough not to hide this useful element “behind».

The work of the scanner does not cause complaints, everything is standard here for the latest generations of such decisions. The finger can bring any angle, the screen activation and unlocking occur for one-touch, press do not need anything, and under the platform of mechanical buttons and no scanner. The scanner works quickly and almost unerringly, even to make a print in the memory is necessary to put a finger not 6 times, and twice as much.

Just above the site of the scanner in exactly the same order as that of the Redmi Note 2, Position Camera flash, but here is already in use are not single and double flash, consisting of two different colored LEDs. To activate the flashlight, it is necessary to shift the menu to the right of notifications, then opens the menu shortcuts to the most important settings. The camera module sticks out beyond the panel, the smartphone is on a solid surface is stable.

The main speaker is displayed here, on the back side of the housing. Holes for the audio output are cut directly into the metal back cover, and it’s bad, because the sound is lying on a smartphone is significantly muted desktop, ringing tone and you can not hear. The majority of the most thoughtful contemporary models speaker output-to-end, where the sound output is nothing blocked can not.

Connector for SIM-card is embedded in the side face, its retractable skids comprise two compartments, in which you can install two cards format Micro-SIM. It does not provide locations for a new and already had time to become more familiar Nano-SIM format, and no space for a memory card. Hot-swapping of cards is supported.

Both side mechanical key installed on the opposite faces of the connector. They are located in the upper half of the body, it is quite comfortable to press either hand. The keys are large, noticeable bulge outside the body, easily found blindly turn distinct and resilient, these items are no complaints.

On the front panel in the upper part of the set of events indicator, luminous round dim LED point in right corner of the window next to the front-facing camera. In setting this indicator, you can change the color of alert or even completely disable it.

At the bottom there is a row of three sensory hardware control buttons with adjustable backlight time. Highlighting this time, not red as in the Redmi Note 2, and the white, almost colorless, and therefore buttons become less distinguishable against the background of light panels, such as the white or golden.

At the bottom end near the hole spoken embedded microphone connector for charging and communication with the computer. There was not used newer USB Type C, such as in Xiaomi Mi 4c, and the usual Micro-USB, USB 2.0 specification supports connection of external devices and a USB OTG mode. On the one hand, it seems to be good for most people, who over time have accumulated a lot of accessories for such a connector. But on the other hand, if too common vector of progress set his sights on a new kind of C, and most manufacturers (including myself Xiaomi, by the way) it is already installed in their smart phones, it would be better not to stretch the process, and quickly complete the transition to the new format – so everything will be easier.

at the top end settled the audio output to headphones and an infrared transmitter to emulate the remote control. The smartphone has its own pre-installed software to control various household appliances via the infrared transmitter.

plugs jacks and outlets are not provided, the machine has not received protection from moisture and dust. Out of his body and fastening strap. Xiaomi Redmi Note 3 has three different versions depending on the body color: The unit is available in light gray, dark gray and golden variants to choose from.



Screen

Xiaomi Redmi Note 3 IPS has a touch screen. Physical display dimensions are 68 × 121 mm, diagonal – 5.5 inches. The screen resolution is 1920 × 1080 pixel density equal to 401 ppi

The width of the frame from the edge of the housing on each side of the screen is about 4 mm from the top -. 14 mm, bottom – 16 mm

The display brightness is automatically adjusted on the basis of the light sensor. There is also a proximity sensor that locks the screen during presentation to the smartphone to your ear. multitouch technology can handle 10 simultaneous touches.

The detailed examination using measurement instruments held partition editor “Monitor” and “Projector and TV” Alexey Kudryavtsev. Here is his expert opinion on the test sample screen.

The front of the screen surface is a glass plate with a mirror-smooth surface, resistant to scratches. Based on the reflection properties of the objects of anti-glare screen is not worse than that of the Google Nexus 7 (2013) (hereinafter referred to just the Nexus 7) screen. For clarity, we present the photo, which is reflected in the screen off the white surface (the left – the Nexus 7, right – Xiaomi Redmi Note 3, then they can be distinguished by size):

The screen Xiaomi Redmi Note 3 only chut a little lighter (brightness images 111 against 109 in the Nexus 7). Ghosting objects reflected in the screen of Xiaomi Redmi Note 3 is very weak, it indicates that the screen between the layers (specifically between the outer glass and the surface of the LCD matrix) no air gap (screen type OGS – One Glass Solution). Due to the smaller number of boundaries (glass / air type) with very different refractive indices such screens look better in high ambient light, but in the case of repair cracked outer glass it is much more expensive, because have to change the entire screen. There is a special oleophobic (grease repellent) coating (performance may even better than Nexus 7) on the outer surface of the screen, so fingerprints are removed more easily, and appear at a slower rate than in the case of ordinary glass.

in the manual brightness control and the derivation of the white box at the top of the screen the maximum value of brightness was about 395 cd / m² minimum – 1.7 cd / m². The maximum brightness is not very high, but given the excellent anti-glare properties, readability, even on a sunny day outdoors should be at a good level. In complete darkness the brightness can be reduced to a comfortable value. The availability of automatic brightness control according ambient light sensor (located to the right of the slot of the front speakers). In automatic mode, when the external lighting conditions, the brightness of both increases and decreases. This function depends on the position of the slider to adjust the brightness. If he is 100%, while in total darkness Auto Brightness function reduces the brightness to 130 cd / m² (too much), in conditions of illumination artificial office light (400 lux) is set to 220 cd / m² (normal), in a very bright environment (corresponds to lighting clear day outside, but not direct sunlight – 20,000 lux, or a little more) increases the brightness to 395 cd / m² (up to the maximum – and need); if adjustment is approximately 50%, the following values: 14, 66 and 395 cd / m² (average bit too low), the controller to 0% – 1.7, 5.7 and 395 cd / m² (for two first values ​​are underestimated) . We are more arranged version with a slider to about 60% of the scale – 30, 105 and 395 cd / m² turns out that locked the brightness function is more or less adequately, and to some extent allows the user to customize his or her work to suit individual requirements. At any level of brightness of the backlight modulation is not significant, so there is no flicker and no screen.

This smartphone uses a matrix of type IPS. The micrographs show the typical IPS subpixels structure:

For comparison, you can see the gallery micrographs screens used in mobile machinery

The screen has good viewing angles without any significant color shift even when large deviations sight. from the perpendicular to the screen and without inverting the colors. For comparison photos, which screens Xiaomi Redmi Note 3, Nexus 7 and displayed the same image, with the brightness of the screen is initially set at about 200 cd / m², and color balance on the camera is forcibly set to 6500 K. perpendicular to the screen white box:

It should be noted a good uniformity of brightness and color tone of the white area. And the test image:

The colors on the screen Xiaomi Redmi Note 3 are clearly inflated saturation, the picture is slightly darkened, and the color balance in the Nexus 7 and the test screen is slightly different. Color saturation is noticeably reduced after selecting Profile Standard in the settings screen:

However, it is still the saturation remains above normal

As shown by further tests achieved this using.
