It has fairly thin bezels and three capacitive buttons namely: Recent Apps, Home, and Back which is very common in most of the smartphones.

The Redmi Note 4 fully made by the metal body which gives it a looks like a very high-end phone. The Curvey look of the phone gives it a very nice and decent look and also making it easier to handle. On the top is the speaker for calls on the bottom speakers for the music along with charging point. On the right side, Redmi Note 4 have a volume rocker and lock buttons. On the left side, you have Dual sim slots.


The front 5-megapixel camera is located on the top of the phone just beside the speaker for the call. On the back side of the phone, we have a 13 Megapixel CMOS camera with dual LED flash. If you compare it with Note 3 it has better picture quality. Just below the LED flash, we have a fingerprint sensor. Fingerprint sensor can be used in many ways like to unlock and selfie click. Overall, Xiaomi Redmi did a good job with the build quality of the Redmi Note 4.

The Display Quality

The phone is equipped with a 5.5-inch IPS, full HD resolution at 1920 x 1080 pixels and 401ppi of pixel density. It makes the display more clear and vibrant. The full HD display offers the color more clear and ambient. For review purpose, we transferred some of the picture and videos into the Redmi Note 4. I must say the quality of the color, clarity, also from the edges, it looks so nice.

The display quality of the Redmi is more like to match with the high-end smartphones. Regarding display quality, it can be viewed properly even at extreme angles. You can also set the color contrast of the screen.


The  Redmi Note 4 is the first phone from Xiaomi that runs on the latest MIUI 8 on top of Android 7.0 Nougat Preview. The phone is loaded with some of the essential apps there no unnecessary apps which you  have to deal. All you need to download the apps which you want from the play store.


MIUI 8 is the latest version of the MIUI, or we can say it is a polished version of the MIUI 7.0. If you are not familiar with the MIUI, then don’t worry it won’t take much time to adjust. Everything is well laid out, and smooth transitions are a joy to see on display. There is a lot more thing that can be customised. Apart from the customisation, it won’t slow down.

The Processor and Storage


The Redmi Note 4 coming in three variant. Redmi Note 4 is loaded with 2.0GHz Snapdragon 625 Octa-core processor, 2GB / 3GB /4GB RAM, 16GB / 32GB/ 64GB internal storage, which is Expandable via microSD, up to 128GB. It is the first phone having the Snapdragon 625 processor. This is specially launched in India only.


The Redmi Note four coming in two variant as we told you. In the both variant camera is the same. The Redmi Note 4 having 13 Megapixel of rear facing the camera with dual led flash and 5 Megapixel front facing the camera.  The 13MP rear camera is phase-detection autofocus both have an aperture of f/2.0. That could be very helpful in low-light scenarios.

The rear camera performs great in bright environments. The Colors and details are beautiful with a bit of high sharpening. If you are a very much social lover and love to post on social media every day, then it’s best for you. The camera has the CMOS sensor So in soft indoor with dim lighting, camera performs well. You can adjust some basic camera setting and get the best pictures.

The Redmi Note 4 can shot the video at 1080p. There is a videos stabilizer function which helps a lot to shot the video. In term of video quality, very much satisfy with that. The color and brightness of the video are so much perfect. Overall I love the camera quality.

The Battery Life


The Remi Note 4 comes up a large 4,100mAh battery. This size of battery provides juice for the device. If you perform some of the basic functions like calling or messaging it can easy sustain two days. We’re able to use it for a full day with some moderate number of activities like calling, messaging, gaming, and music streaming. There is also a battery saver feature if you’d use that, it’ll easily go for two days or even more. The Charging might take time around an hour and 40 minutes using the included 5V 2A charger.

The Performance

Regarding performance, Redmi Note 4 did a good job. The Redmi Note 4 is powered by new Snapdragon 625. Our model comes with 4GB of RAM and we are pretty much satisfied with that. The phone perform well in high-quality gaming mode. You won’t face any kind of lacking through gaming. Games like Asphalt 8, Nitro, H.A.L.O 3 are running very smoothly. Overall it won’t heat much with compare to other phones.


As an everyday user, the Redmi Note 4 will not disappoint you. If you are looking to buy a budget smartphone, then we must suggest you buy this. It offers you the best quality product. Redmi Note 4 build is also attractive and solid. This will make it more user-friendly to a user. You can share your views with us through comment.
