The Redmi Note 4X is a mid-range smartphone from Xiaomi that once again offers some exceptional hardware at a starting price of just $175. It is a variant of the popular Redmi Note 4 with extra LTE bands, Bluetooth 4.2, and a compass. The device is likely intended to be launched in markets where the MediaTek-powered Redmi Note 4 is already available.

Hardware and design

The Redmi Note 4X isn’t something radical or new as the Redmi Note 3 or the Redmi Pro in terms of design. It seems like an evolution of the Redmi Note 3’s design language in a slightly thinner body, with gradually curved edges. The back of the device is made from aluminum, while there are plastic strips at the top and the bottom. It isn’t a unibody construction but does give an illusion of being one.

I got the grey coloured variant of the device, which looks quite good. The black version with an iPhone-esque finish could be better in the looks department, but this one looked fine to me. On the front, the smartphone is covered with black 2.5D curved glass that comes with scratch resistant coating. There is no mention of Gorilla Glass, so I would recommend using a screen protector on the device.

The button and connector placements are similar to other Redmi devices. The volume rocker and the power button are on the right edge, while the micro USB port is flanked by the speaker and mic grilles at the bottom. The 3.5mm headphone jack, the IR blaster, and a secondary microphone are present on the top.

Display

Xiaomi has continued to use the same display specification as the Redmi Note 3 in the Redmi Note 4 and 4X. It is once again a 5.5-inch IPS LCD panel with Full HD (1920×1080) resolution. With 401 pixels per inch, it is still a decent display in this price range, and the color quality and contrasts on this one in particular are very good.

The colour calibration out of the box is top notch with the right amount of vibrancy and close to natural shades in almost all situations. It is a highly readable display in all lighting conditions, and it can get very bright under sunlight. The capacitive buttons at the bottom are backlit unlike the cheaper Redmi phones, which is very helpful when using the phone at night.

Camera

Xiaomi Redmi Note 4X camera

Xiaomi has used a 13-megapixel rear shooter made by Samsung in the Redmi Note 4X. It features a f/2.0 aperture and individual pixel size of 1.12 µm. The camera captures a lot of light and produces very good images in most conditions. The software is very fast and packed with features such as beauty mode, manual controls, hand-held twilight mode, and more, which add to the imaging experience on the device.

The rear camera supports 1080p video capture at 30 frames per second, and 720p capture at 120 frames per second. Video capture is not that good on the Note 4X, and the lack of image stabilization is very obvious. The output in daylight is much better than low-light, but neither of them can be termed as good. Macro shots in daylight are exceptionally good for a smartphone priced in the mid-range. Distant shots tend to lose some detail but the HDR mode helps to a certain degree in such situations.

The front camera is a 5-megapixel unit with f/2.0 aperture. It does not feature autofocus or wide-angle capture, which could be an issue for some buyers interested in taking selfies. I was fine with the general results of the front camera, but there definitely is pixelation and noise even in daylight images taken from this camera.

Performance

 

There are two versions of the Redmi Note 4X available, one with 3GB of RAM and 32GB of internal storage, and the other with 4GB of RAM and 64GB of storage. The one that I received for review was the former, which is priced at about $175.

Under the hood, the chipset and other specifications are same across both the versions. The Redmi Note 4X packs an octa-core Qualcomm Snapdragon 625 system-on-chip built on a 14nm process. It is highly efficient, and performs very well. Coupled with the Adreno 506, the gaming performance of the system is also decent enough for almost any game available. 

Battery

A large 4100 mAh battery paired with the power efficient Snapdragon 625 gives extremely crazy uptime on the Redmi Note 4X. The phone lasts for over a day and a half on a single charge with moderate to heavy usage, and gives an impressive screen on time of over 10 hours with all background services enabled.

Conclusion

It is almost a no-brainer for anyone looking for a smartphone priced under $200 to opt for the Redmi Note 4X, but there are still some caveats. The device’s availability is very limited like almost all Xiaomi smartphones. In some markets the Snapdragon 625-powered Redmi Note 4 is available already, which is almost the same device and shares all the positives of the Note 4X.
