Redmi Note 4

In January 2017, the Snapdragon version of the Xiaomi Redmi Note 4 or Xiaomi Redmi Note 4X became the company's first major launch. It came with 2GB RAM + 32GB eMMC, 3GB RAM + 16 or 32GB eMMC and 4GB RAM + 64GB eMMC variants. The phone sports a 5.5-inch Full HD IPS display (1080 x 1920 resolution), translating to a pixel density of 401ppi.[6] The display also promises to have contrast ratio of 1000:1 and 72% coverage of NTSC colour gamut.[7]

On February 14, 2017, alongside the Chinese release of the Redmi Note 4X, Xiaomi released a limited edition set of the phone featuring Hatsune Miku. The set contained a customized box, the phone, a power bank and a protective case.

In October 2017, Lei Jun announced that the sales of Redmi Note 4X exceeded 20 million units globally and its reputation was good.[8]

The company announced that as many as 9,624,110 units of Redmi Note 4 were sold in India in 2017 and that it was one of their best-selling smartphones in the last quarter of 2017.[9]

The device sold over 10 Million units in India alone.[10]

The company discontinued the smartphone's sale in favor of the successors Redmi 5 and Redmi Note 5.

The smartphone received mostly positive feedback upon its launch because of its great battery life, CPU performance, good thermal performance, great price-to-performance ratio and a great day-to-day performance.

GSMArena states: "The Redmi Note 4(X)'s Snapdragon 625, which we consider to be the ultimate mid-range chipset for this generation, provides excellent performance with great power efficiency and thermal properties. The battery life of this phone is jaw-dropping, the MIUI experience is smooth, and the camera does well in all occasions. All these goodies come in a sturdy metal body, which adds to the already great value of the Redmi Note 4(X)." Also, in GSMArena's device review, the Snapdragon edition of the phone scored much better than the specified figures, getting a 1500:1 Contrast ratio, 484nits of maximum luminance and excellent colour accuracy for the class.

According to AndroidAuthority: "The Redmi Note 4(X) is not perfect, but it is a well-rounded package that one wouldn't hesitate to recommend to anyone looking for a budget or mid-range smartphone. Packed in a neat chassis, the smartphone performs great and is a compelling value-for-money smartphone."[17]

Gadgets360 also rated the phone 8 on 10, appreciating the device for its battery efficiency, good performance for the class and good thermal efficiency.[18]

AndroidCentral also considered Redmi Note 4(SD variant) to be one of the best smartphones one can buy in the mid-budget range even after 6 months of launch.[19]

TechRadar called Redmi Note 4 to be an overall impressive device overall, though lacking the X factor, getting 4/5 ratings.[20]

Initially, upon launch, it was not received as the true successor of the Redmi Note 3(Snapdragon Variant) mostly because of the use of the Snapdragon 625 as opposed to the Snapdragon 650 in Redmi Note 3 in terms of the RAW performance of the CPU and GPU. Though perceived initially as a theoretical downgrade by media, XDA Developers also considered the device an upgrade to Redmi Note 3, citing its overall sustained performance, on par day to day performance and better battery and thermal performance by a good margin.[21][22] The new Snapdragon 625 was well received by users as well as reviewers after using the device for a while owing to the better fabrication process, battery life and thermal efficiency of the new chipset over the Snapdragon 650.
