review with features, price and specifications

23 mayo, 2021

After launching in China the Redmi Note 8 and Note 8 Pro, and the Redmi 8A, Xiaomi officially presented the Redmi 8, a mobile that straddles the two previous ones, with the same processor as the 8A, but with some additions such as the double camera, the presence of the fingerprint reader and an increase in RAM and storage.

Recently, the Redmi 8 has arrived on the market and it has done so to succeed the Redmi 7, placing a notch below the Redmi Note 8T, both in price and performance. After testing it for a few days, below we will tell you how it behaves in each of the sections, including that huge 5,000 mAh battery supports 18W fast charge.

A good speaker and a nice packaging

Redmi 8 02

Although this model belongs to the company’s entry range and is obviously made of plastic, Xiaomi has equipped it with a shiny back that conveys the sensation of glass to the eye and to the touch. That, added to its rounded corners and a slight curvature in the body, gives the whole an attractive appearance. In the hand, it feels firm and comfortable, although somewhat heavier than it actually is (188 grams).

On the back, sapphire blue in our case, in addition to the fingerprint reader and the Redmi logo, we have the two sensors of the main camera and the flash, all vertically aligned in a strip of black tonality. There are two aspects that we appreciate here: the camera module barely protrudes from the body and the dirt, although present, is less noticeable than on the glass.

If we now look at the front, we find a 6.22-inch IPS LCD screen with HD + resolution, a drop-shaped notch and frames (except for the bottom one) quite tight for a phone in this category. This panel shows some acceptable viewing angles and maximum brightness that allows good viewing even in direct sunlight.

However, the automatic brightness performs worse and slower than we expected: generally, gives us a level of brightness much lower than adequate and many times it forces us to correct it manually. The colors are somewhat cold, but we can always modify the contrast or tonality with the customization options that MIUI offers.

Redmi 8 04

We move on to the sound section, where the Redmi Note 8T has a single speaker at the bottom that delivers a fairly powerful sound with a fairly good quality for a phone in this category (except if we turn up the volume too much, which distorts). It has a jack socket, although it does not come with headphones in the box, and it incorporates a wireless FM radio that works without the need to connect headphones.

Approved high in performance, outstanding in autonomy

Redmi 8 07

Its brain is an eight-core Snapdragon 439 that runs at a maximum speed of 1.95 GHz and is accompanied by an Adreno 505 650 Mhz graphics card. It is surprising that Xiaomi has opted for this low-end chipset if we consider that its predecessor mounted a Snapdragon 632, but it is well optimized. The unit we have tested is the one that includes 3 GB of RAM and 32 GB of internal storage expandable with a microSD card, but a 4GB / 64GB variant is also available.

The performance offered by the Redmi 8 has pleasantly surprised us, although we have suffered some delay when scrolling on web pages or on social networks

In practice, the performance offered by the Redmi 8 has pleasantly surprised us. Do a good job in multitasking and navigation through menus and between apps is quite fluid, although we have suffered some delay when scrolling on web pages or on social networks. Except for a certain moment (such as when testing it with games like Asphalt 9), it does not get too hot or experience sudden shutdowns.

As an operating system, it brought MIUI in its version 10.3.1 on Android 9 Pie, but it was soon updated to MIUI 11. As we always say, Xiaomi’s layer has its positive points (such as its extensive customization options and several very practical tools) and its negative side, caused by the large amount of bloatware that comes pre-installed with several duplicate apps and third-party apps (some can be uninstalled). This means that, of the 32 GB capacity, a little more than 19 GB comes free of charge, although we can always use a micro SD card to expand it.

In the biometrics section, it includes fingerprint reader and facial recognition based on artificial intelligence, something that is appreciated in an entry-level mobile. Both are relatively fast and effective, except when the light conditions are unfavorable, which shows many difficulties to recognize our face.

And now we turn to the highlight of this mobile: its 5,000 mAh battery with 18W fast charge. On paper, Xiaomi promises 3 days of normal use with a single charge and the truth is that, without reaching that figure, yes easily exceeds 2 days. It usually offers between 9 and 10 hours of screen depending on how much we squeeze it and whether we use automatic brightness or not.

The 18W charger included in the box is not 18W, but 5V / 2A, but still takes less than 3 hours to fully recharge. To give you an idea, in half an hour plugged into the power, you get 23-24%, which we assure you they give for many hours of use on this mobile. By the way, it has USB-C, while its predecessor, the Redmi 7, integrated a micro USB port.

Cameras that meet during the day, but not at night

Redmi 8 03

We finish, as always, with the photographic section, where this Xiaomi model has an 8 MP front camera with an f / 2.0 aperture and on-screen flash. Rear camera mounts a 12 MP Sony main sensor with f / 1.8 aperture and another 2 MP sensor to make depth measurements. Added to this are FullHD video recording at 30 fps, Xiaomi’s usual camera app (intuitive and with the necessary shortcuts) and artificial intelligence for automatic scene recognition.

And how do those cameras behave? The rear fully complies in favorable light conditions, although sometimes it overexposes the skies. AF is fast, but not always successful at short distances. In any case, the level of detail and dynamic range, without being spectacular, are acceptable for a mobile in this category.

Redmi 8 Day Photo mode with AI and HDR activated

Although the Redmi 8 is an entry model, its camera offers a multitude of possibilities, such as a professional shooting mode that allows us to manually modify the white balance, the aperture of the diaphragm, the shutter speed and the ISO sensitivity. It does not count as optical zoom (and the digital one is better not to use it), but it does have a Portrait mode that, without being a marvel and without letting us adjust the background blur, is not bad. Automatic scene recognition, in general, is quite efficient and HDR can help us save a scene with great light contrasts.

At night or in low light conditions, the quality of images is greatly reduced. A lot of noise appears, a lot of detail is lost and the lights are blurred. The flash, as usual, burns the photograph, so it is not recommended to pull it.

Redmi 8 Night Photo mode with AI on

With the front camera, something similar happens: when there are good light conditions, the results are more than acceptable, with a good level of detail and a fast and effective AF, although it tends to overexpose the background, especially in Portrait mode (which uses software to achieve the bokeh effect). It also includes HDR (which we recommend turning it on automatically), filters, and a multi-level adjustable bezel.

At night, however, the noise becomes very evident and a lot of detail is lost; the on-screen flash doesn’t help either, as it causes very artificial lighting. In short, if the lighting conditions are not good and we do not have any source of light (streetlights, spotlights …), the front camera of the Redmi 8 will only help us to obtain testimonial images. But be careful, let’s not forget that we are talking about a terminal of 139 euros.

Redmi 8, the opinion of Xataka Android

Redmi 8 08

As we are used to by Xiaomi, the Redmi 8 is a terminal with an excellent value for money. It does not fail in any of the sections and in some of them he even gets a very good grade. For 139 euros, we have a phone with an attractive design, a good experience in terms of display and performance, and cameras that, while kneeling in low light, do offer a lot of possibilities and produce attractive images when lighting is favorable.

Its battery allows us to forget about the plug for two days and, when we have to resort to it, it gives us a fairly fast charge

Special mention should be made of its battery, which allows us to forget about the plug for two days and, when we have to resort to it, it gives us a fairly fast charge. Good work here, Xiaomi. We also do not forget some additions such as P2i splash guard and Corning Gorilla Glass 5 glass of the screen, the included silicone case, the infrared port for the remote control and the USB-C port, although it is true that it lacks NFC. As for the operating system, if you are not an Android purist, it must be recognized that MIUI is on the right track and is …
