Review Redmi 7: strong upgrade compared to Redmi 6 – VnReview


As competition intensifies, you must understand that a smartphone that focuses on configuration and battery life alone is not enough. If you do not change, you will definitely fall behind.

Redmi 7 is one of the first smartphones to mark the change of Redmi after separating from Xiaomi, and of course they want users to know that change. After many generations of "same same" Redmi look boring to "bland", Redmi 7 is the first time this cheap phone has a significant change in terms of design. Of course, not every change will certainly bring positive feedback, but when the competition is getting tougher, you must understand that a smartphone focused on configuration and battery life alone is not enough. If you do not change, you will definitely fall behind.

VnReview version on hand today has 3GB RAM, 32GB internal memory with a selling price of 3.69 million. It also has a more expensive version with 4GB of RAM, 64GB of internal memory but only for the Chinese market, and a cheaper version with 2GB of RAM, 16GB of internal memory for $ 2.99 million.

Design: "Twins" of Redmi Note 7 but more "inferior" body

Goodbye aluminum back face, Redmi 7 has switched to using plastic imitation glass material with a gradient and more eye-catching gradient effect. Although there is no feeling of creaking, plastic material on Redmi 7 clearly cannot "be happy" with Gorilla Glass 5 of Redmi Note 7, but at least it is not as boring as the design of the previous Redmi series. Version of VnReview is blue, in addition to this color, Redmi 7 also has two more color versions of red and black like Redmi Note 7.

The frame of Redmi 7 also uses plastic material but is not coated with shadow, and the machine also "inherits" the plastic layer around the screen border of Redmi Note 7, making the frame without the seamless and causing hands when Hold or swipe the edge. The size and weight of the device is also much larger than that of Redmi 6, but in return we have a bigger screen and a higher capacity battery.

Separating as a private brand also means that there is no Xiaomi logo on the phone. The back of Redmi 7 is basically the same as the Redmi Note 7, except for the text that annotates the camera and the sides are slightly curved for a more comfortable grip.

The ports, the physical key position of Redmi 7 are almost identical to Redmi Note 7, except that the machine does not have a USB Type-C port, instead of the old microUSB port. Because Redmi 7 is a low-cost device, the battery does not support fast charging, which is also acceptable.

In general, although some minor minus points exist, the change in design of Redmi 7 can be considered a plus. However, if there is a better "purse", the Redmi Note 7 will be a more comprehensive choice of design, not including the difference in configuration.

Screen: Leap in size, resolution footprint

Not only keep up with the trend of changing the back color of the gradient, Redmi 7 is also equipped with a water drop screen – the preferred solution to maximize the screen area. As a result, the screen of Redmi 7 can increase by almost an inch compared to Redmi 6 – from 5.45 inches to 6.26 inches – but the overall size of the machine is still not too different from the man.

The water droplet part of Redmi 7 only contains selfie camera so the area for the notification bar is very wide, allowing you to display more information. However, the "chin" and the thick edges of the camera make Redmi 7's screen / body ratio about 81.5%, slightly lower than Mi 8 Lite's rabbit ears screen (82.5%).

Redmi 7's IPS LCD screen offers wide viewing angles, good color reproduction, but the resolution only stops at HD +, making the image not very sharp. At 6.26 inches in size, FullHD + resolution will be more suitable, but of course that will make the price of the product be slightly raised. The brightness of the device is sufficient for most everyday situations, as long as it is not under direct sunlight.

Good performance in price range with Snapdragon 632 chip

Redmi 7 is the first smartphone equipped with Qualcomm's Snapdragon 632 chip. This can be called an upgrade for the legendary Snapdragon 625 chip that appeared on many of Xiaomi and Redmi models before. With 8 cores clocked at 1.8GHz and 3GB of RAM, playing light games is completely within reach.

With the popular MOBA Mobile MOBA game, Redmi 7 has no high frame rate option but is locked at 30 FPS. Frame stability at 89%, slight slight fluctuations in effects scenes

Dead Trigger 2 at the highest graphic setting does not harden Redmi 7. The device remains at 60FPS, frame stability is at 90%

PUBG Mobile may be slightly out of reach of Redmi 7. Even at the lowest graphic setting, the average FPS of the machine is only 29, the frame stability is 79%, the device is hot fast and the experience is not smooth.

In the familiar benchmark post, the score of Redmi 7 is slightly lower than the 636 Snapdragon-based smartphones that VnReview previously evaluated.

About the software, Redmi Note 7 currently installs MIUI 10 version fully supports the familiar features of Xiaomi home like the second space to store private data, dual application runs two Facebook or Messenger accounts … On the same phone, lock the application to password protection and support many phone control operations with gestures.

Large capacity battery for comfortable use, without fast charging

Redmi 7 owns 4,000 mAh battery, equal to Redmi Note 7 and is much higher than Redmi's 3,000 mAh figure 6. Combined with HD + screen resolution and Snapdragon 632 chip saves energy and time Redmi 7's battery capacity can be up to 1.5 – 2 days with average usage frequency.

That's the big battery, but Redmi 7 doesn't support fast charging. The device comes with a 5V-2A charger, to fully charge the 4,000 mAh battery that takes about 2 hours and 15 minutes.

Don't expect too much on cameras in this price range

After all, Redmi 7 is still a low-cost device, and when the design, configuration and battery all have certain upgrades, there must be a sacrifice, and specifically the camera.

The familiar camera interface

Briefly on configuration, Redmi 7 owns dual camera cluster with 12MP main camera, f / 2.2 aperture, 1.25µm pixel size, phase assist, combined with secondary camera measuring depth of 2MP image field. Through these parameters it can be deduced that low-light photos will definitely be the weakness of Redmi 7, like other low-cost machines.

In bright enough conditions, the Redmi 7's camera gives good quality in price range, detail, bright band, and color reproduction capabilities that you can expect from a cheap smartphone. However, the automatic HDR mode tends to balance the light in an "excessive" way, making the image look slightly dull even when it is quite bright.

There is a point to note is the night mode (Night Mode) has "disappeared" on Redmi 7. In the reviews of the smartphone Redmi and Xiaomi before, Night Mode mode is really effective, so the loss This has great significance. Low light photos of Redmi 7 only have quality in medium, noise, low detail. This is predictable with Redmi 7's camera cluster specifications.

Camera for measuring the depth of field of Redmi 7 only has 2MP resolution, instead of 5MP like Redmi 6. However, the font removal mode still works quite well, especially in favorable lighting conditions, the background can be smooth erase, quick entry into the subject at an acceptable level, only difficult at places such as curls or shoulders.

The front of Redmi 7 is a single selfie camera with 8MP resolution, f / 2.0 aperture, and a pixel size of 1.12µm. Photos taken often and photos removed fonts in bright enough conditions at a decent level, colors and details are acceptable, but when shooting in low light, the image is more noise, the color of the skin is weak and the background is often sneaked into the subject. The hardware limit has only one camera.

Summary: strong upgrade compared to old life

Redmi 7 has changed almost in every way compared to previous Redmi smartphones and most of them have a positive trend. Although there are still points that can be overcome or better done, but from design, configuration to battery and camera time, they still meet the needs of everyday use and really hard to expect. more than that at a smartphone at more than VND 3 million.

However, the problem of Redmi 7 is that its price is very different compared to "his brother" Redmi Note 7 (the lowest configuration has 4 million VND) with many advantages such as camera, performance power, Type C port to fast charging capability.
