Xiaomi Redmi 4, the latest launch from Xiaomi is the aggressively priced budget phone from Xiaomi that intends on killing all the competition from the market. The phone has been launched with the sole intention to drive every user with a small budget towards Xiaomi phones. The latest example of this was seen in the flash sale in India by Amazon. All the phones, of all the variants, were all sold out within minutes of beginning the sale.

What is it with the phone, that is winning so many hearts and is going out of stock right away? We took out some time and went on to find out.

Design & Display

Being a budget oriented, there is not much fancy in the display of the phone. We have a 5-inch 720p HD IPS LCD, that can produce 16M colours. This is similar to other phones in this segment. What stands out is the design. Xiaomi did a fantastic job of using a curved 2.5D design for the phone’s body. The phone looks very beautiful. We were so impressed we ordered one for testing right away.

When the phone arrived, we were awestruck by the looks of the device. The device looked so premium just to hold. The screen size and the bezel ratio was perfect to hold in hands.


When we saw the specs sheet of the Redmi 4, we were astonished at the camera specs. Xiaomi has installed a 13MP f/2.0 Ultra-Fast PDAF camera. Without delay, we sent one of camera enthusiasts to fetch some camera samples. The images were more than just good. They were absorbing. We kept looking at the pictures; they were simply great. Here are a few camera samples:

The camera took sumptuous photos that seemed out of the world. For a phone priced this low, the quality is very good, and the phone did win our hearts in this segment.


The phone has a whopping 4100 mAh battery that lasted for a full two days for us. We were amazingly impressed by the backup we got from the phone. Even after playing games, using the camera, continuously surfing the internet, keeping social media on, having more than a dozen apps open, the battery did last very long. The phone once again won our hearts.

What the world has to say

The phone was launched in China in November last year and has since then found a lot many fans, with great reviews from all over the world wherever the phone was exported.

The phone has found a lot of fan following, mainly due to its pricing and availability with large specs at a low price.
