Xiaomi Redmi K40 Review: A Great Deal In This Price Bracket

Xiaomi Redmi K40 Review

In 2021, Xiaomi announced the Redmi K40 (M2011K2C) smartphone. It has a Qualcomm Snapdragon 870 processor, 6 GB of RAM, and 128 GB of internal memory.

The Xiaomi Redmi K40 comes pre-installed with Android OS v11.0. The battery is a  non-removable Li-Po 4500 mAh. It has a 6.67-inch IPS display with a resolution of 1440 x 3200 pixels. 

In terms of cameras, the Redmi K40 has a triple camera arrangement on the back, with a 48-megapixel primary camera with an f/1.79 aperture, an 8-megapixel camera, and a 5-megapixel camera. Autofocus is available on the back camera. It includes a single selfie camera with a 20-megapixel sensor on the front.

The Redmi K40 contains 128GB of internal storage and has MIUI 12 from Android 11. The Xiaomi Redmi K40 is a dual-SIM (GSM and GSM) smartphone that takes Nano-SIM and Nano-SIM cards. The Redmi K40 weighs 196.00 grammes and is 163.70 x 76.40 x 7.80mm (height x width x thickness). It came in three colours: Dreamland, Glossy Black, and Icy White.

Xiaomi Redmi K40 costs Rs. 22,490 in India.

Design

The Redmi K40 is packaged in a standard-size box. The charger and cord that had vanished from the Mi 11’s box have reappeared in the K40’s. A 33w charger is supplied, and we’ll get into it later.

It is only 196g in weight and 7.8mm thick. The Mi 11 design is carried over to the whole back. The camera module is more extended, and the parts are more uniformly distributed. This improves the back’s appearance over its predecessor. The main hue of the K40 is a red and blue gradient. In various lighting, it refracts blue and red.

The fingerprint sensor incorporated in the power button on the side is slightly elevated. This is the first time Redmi has been able to compete with Xiaomi in terms of design.

Display

The K40 series features a flat E4, 1080p, 120hz refresh rate OLED panel this year which is one of the K40 series’ primary selling factors is the screen. The performance is genuinely excellent, with 1300 nits of peak brightness and a 5,000,000:1 contrast ratio while consuming 15% less power. Multi-finger control should be more responsive than previous phones, thanks to supporting a three-finger 360hz touch sample rate. However, the user perceives the improvement in experience more than the improvement in parameters.

Gaming & Performance

The Snapdragon 870 is a well-balanced processor, as you may have seen in other phones like Motorola Edge S. It was not a pleasant experience. So it appears that the phone delivers a superior gaming experience than the Edge S for titles that were optimised for the Redmi model. And the temperature never rose over 50 degrees Celsius. The gaming experience would be poorer than the Edge S if there were no focused improvements.

Camera

Autofocus is included on the Xiaomi Redmi K40’s camera. Autofocus is a camera function that fine-tunes the camera’s focus; it’s a useful feature on this smartphone. , The back camera incorporates optical image stabilisation (OIS) to prevent camera shake.

In real life, the main camera on the K40 underexposed samples in the daytime. The dynamic range is likewise lacking, with significant detail loss in dark places. The resolution is insufficient and colours are also lacking in vibrancy. . The K40 loses out in all daylight scenarios, except for somewhat improved management of the purple-fringing problem.

Battery

A 4520mAh battery powers the K40. According to our inspection, a half-hour of Tiktok and a half-hour of 1080p online video utilise just 5% of the power. The Genshin Impact wastes 18% of your time after 30 minutes. The BrightRidge uses 20% of your time after 20 minutes. This optimization of the battery is still decent.

Although the K40 still uses 33 watts for charging, it has been greatly improved. It charges up to 69 per cent in half an hour and takes 54 minutes to completely charge. As a result, this is faster than the 40w charging of many other models.

Takeaway: Excellent Smartphone In A Budget

To summaries, if you’re searching for a phone with good performance, minimal heating, and a camera that’s not too demanding, the K40 is an excellent choice. There are a few unexpected features, like the superb E4 screen and stylish design. Given its flaws, it isn’t the best phone, but it is the most comfortable phone in this price range, at least for the time being.
