We got the early Unit for Redmi Note 4 to Test and Review from China, so let’s see how it actually performs and daily use.

In my case everything was being included that amount.

Design & Built

The Device which I have used to review is a 3GB/64GB Model. There is also a Lower end Model which you can buy as per your budget.

Now starting with the Design and the built of Redmi Note 4, this times the phone houses in Full Metal Chassis and no plastic is being used in its built. The design seems to be inspired from its previous models but this times the back curved has changed into flat smooth back. Note 4 adds curves on the edges to add a perfect the grip while holding it in hand.

The successor of Redmi Note 3, has made a few changes in its updated Note 4. This times they have also added a 2.5D curved glass on its 5.5″ Display panel which adds extra protection as well as looks to the phone.Xioami Redmi Note 4 techniblogic

On the Top portion of the phone, you will get a 3.5mm audio jack, beside it an IR blaster and a secondary MIC over there. Xioami Redmi Note 4 techniblogicTurning around to the down portion, it houses dual Speaker grill, out of which left one is having a primary mic and another one is having an actual speaker in it. Between those speaker grill houses a normal micro USB port.

Xioami Redmi Note 4 techniblogicComing to the left side of the phone you will get a supports Dual Sim at the same time or single sim + Micro SD card up to 256 gigs which make it a hybrid SIM tray.

Xioami Redmi Note 4 techniblogicTurning around to the other side of the phone you will get volume rockers and below that power lock key which give quite good tactile feel.

At the back panel of the phone you will get a 13 MP camera below that Dual Tone LED Flash and below that a FingerPrint sensor which works perfectly even with 360 Degree Recognition. Just put your finger on it and in 0.2 ns or may be less it will unlock the device.



Xiaomi Redmi Note 4 comes with a 5.5-inch FHD with a resolution of 1920 x 1080 and pixel density of 401ppi. The Display colors are more natural, and blacks are proper dark which means while watching movies and playing games the experience which you will get is going to be awesome. The Sunlight legibility this time in Redmi Note 4 is not as good when we compare it will be its previous device which was Redmi Note 3. May be it is because this time colors are more natural and darks are more deep. The Brightness level of Redmi Note 4 is also a bit low compare to redmi note 4, but overall the screen for movies and games and daily use is much better. This time you won’t be getting more strain on your eyes while using or reading books on the Phone just because of deeper blacks and natural colors.

Viewing Angle is good and you won’t be getting any chance to complain about it. While watching movies from odd angle won’t affect you in any way. There are different color modes, which you can change as per your usage by going into the setting panel.



The phone comes with Mediatek MT6797 Helio X20 Deca-core processor clocked at 2.1 GHz which features a 3GB/2GB Ram. This combo makes it a perfect device with this price. Out of 64 GB of internal storage you get about 56 GB free, even after that you can expand it to up-to 256GB because the phone support Hybrid SIM tray.

This power of Deca-core processor won’t disappointing you in any way. We can run multiple apps and games on continuous bases and experienced no lag or frame drop or glitch at all. But here i wanna add one more point that in MIUI 8 there is a function using which you switch the mode.

  1. Normal Mode –  In this mode you will be getting better battery, with best possible optimized power in the phone. It optimized the phone in such a way that it will give you more battery life with minimal effect in performance which is not noticeable until and unless you are playing high intensive games on normal mode. The Antutu Score of normal mode is also a little bit low compared to Performance mode.
  2. Performance mode – In this mode most of the cores start working by giving you the maximum power for any kind of high intensive work. In this mode Antutu Score is way better as well as the gaming is lag free, even by using the PSP EMULATOR you can play GOD OF WAR Series on your Redmi Note 4 Flawlessly. Now you can assume its hardware and its performance in performance mode. One more thing I wanna add over here is that even after long high-end gaming we won’t found any heating issues.

Over all, you can do intense multitasking on Redmi Note 4, and you won’t face any lag in daily use just be careful which mode are you using and which is your priority.

So, this time Redmi note 4 comes up with 13 MP rear Camera with some improved camera app with its latest MIUI 8. This time they have improved a lot with there sensor and much better bokeh effect while focusing from rear camera. This time focus is also much better and fluid. The images came out really good with some great colors and saturation. Rest, I have already posted different camera review on my YouTube channel.Coming to the Low light images, it comes up with a little bit noise.

Coming to the front facing camera of 5 MP which according to me do not perform well just like the previous one.

Xioami Redmi Note 4 techniblogic While taking selfie you won’t notice much because those shots are taken using the beauty mode on, rest as per my views I don’t like Redmi Note 4 front facing camera. If I compare it with LeEco le2, front cam is much better than redmi note 4 don’t know why this has been done by them.

Rest you can check the video comparison of LeEco Le2 camera vs Redmi Note 4 Camera.


Redmi Note 4 out of the box is loaded with MIUI 8 which is the latest release from Xiaomi as of now. It is loaded with some really awesome features, and the best among them I like is the Dual app mode and Dual System using which you can live you personally and office life in two parallel ways.

Rest I have already made a separate video on it, which explains all the features which are there in the Software. So do check it out:

As we all know Xiaomi always offers some great battery life to there device, so as this time. Redmi Note 4 is packed with a big battery at 4100mAh, as well as the software is enough power for optimizations under the hood that makes it last really long.

As of now there is no USB Type-C, but still they have added a new feature of MediaTek PumpExpress 2.0 technology for fast charging, which works decently while charging the phone. But still they should add Type C for better charging.


The Redmi Note 4 is a pretty decent smartphone for its price. It performs pretty well with no complaints. Overall, for normal as well as for heavy user it is the perfect device. But coming to the selfie lover, I will just say no to them.


  • Metal chassis with 2.5D display
  • Decent Performance
  • Long battery life
  • Great price


  • Worse Front camera performance
  • No USB Type-C
