Redmi Note 4 buttons and ports


The Snapdragon 625 octa core 64 bit processor clocked at 2GHz with Adreno 506 GPU does an excellent job. Though the benchmark scores are lower than Redmi Note 3 you will hardly notice any difference in the performance.

Best part is that the handset does not heat up. The maximum battery temperature I encountered was 37 degrees. In fact when compared with other handsets the battery temperature is way low (also not to forget its winter season), but still temp is lower compared with other handsets.

Nenamark 2 : 60.1fps
Disk Speed : 216 MB/s read / 151 MB/s write
Multi Touch :10 point


Both Modern Combat 5 and Asphalt 8 games were playable, smooth, no lags. The best part was the handset battery temperature – max battery temperature I encountered was 37 degrees. .

Redmi Note 4 did not heat up when playing games. Perfect for gaming users, especially those who spend a lot of time playing games on their mobile phone.


There is 13MP camera on the back and 5MP on the front. Camera quality is above average (make sure to update the OS / also check this page for Redmi Note 4 camera review video). Note 4 can shoot FHD videos. The hardware is powerful, it can play 4K, but the camera app gives max 1080p recording option.

The finger print sensor on back is fast and accurate. Sound is loud, did not find any issues with VoLTE, reliance Jio worked. WiFi, Bluetooth and GPS worked well.

No others issues, sound is loud, WiFi (dual band), GPS, Bluetooth, IR worked well.


There is a 4100 mAh non-removable battery. Battery life is awesome – you will get 9 to 10 hours of non-stop moderate to heavy usage. With mixed moderate usage you can expect an easy 2 days of battery life.

Redmi Note 4 Battery Performance (time / battery % drop / estimated battery temperature)

  • Running Benchmark app – 12 minutes / 2% / 33 degree
  • Asphalt 8 game play – 19 minutes / 3% / 37 degree
  • 4K video playback with full brightness (WiFi /4G on) – 27 minutes / 5% / 35 degrees

It took me 2 hours 30 minutes to charge the handset from 0% to 100% using wall charger.


If you compare Redmi Note 3 and the Redmi Note 4, benchmark scores are higher on Redmi Note 3, but in real usage scenario you will hardly find any differences. Battery life is even better on the Note 4. Also heat up is much less on the Note 4 when compared with Note 3.

If you have used the Redmi Note 3, you can upgraded to Redmi Note 4.

    Please clarify.

  2. How much time required to delivery ?
    I have booked redmi note 4 4gb of worth12999 rs on mi.com how much time i have to wait for my dream smartphone?

  3. avoid redmi note 4 and honor X, both have low sound due to single speaker, awfully low sound when outdoors, screen, camera and battery is good, but sound is BAD for both, heating up is sure for redmi phones due to metal back. excessive heat during charging.

  4. Gogi sir, I got my redmi note 4 today and it is heating while charging. It is surely above 40 degrees. Is it normal as u have encountered maximum 37 degrees?

    1. Yes normal when charging it heats up. After 90% and over it will tend to cool.

    1. Not sure you can try the following
      1. use the SIM from a different location say 5KM to 10KM away so as to see if it is not vodafone signal issue.
      2. Does the same SIM work on different phone from same location?
      3. Go for a SIM card replacement you should get it from vodafone store for free

  18. Is it advisable to purchase the 2gb variant of Redmi 4?
    Request proper guidance from friends. Thanks


    1. I am using redmi note 4 of 4gb+64gb variant. The performance is awesome you can compare this performance with iphone 7. Best phone in world under 15000.

    2. Have both the phones with me. In my opinion, you should go for Redmi Note 4 because of the advantage in terms of battery backup and less thermal temperatures under load while gaming.

      1. Mi care replied my question

        I would like to inform you that Redmi Note 4 has been made with corning glass which is as strong as gorilla glass.

          1. Ha ha ha sorry for the disturbance. But I expecting ur pin test, but missing this review

  20. I got an MIUI update of 1.4 GB, is that the update you said improves the camera quality as it was not mentioned anywhere. OR do I need to download some other update ? please Help..!!

  21. Does Redmi note 4 has better camera than redmi 3s prime, I am tired of poor battery life of phones even with my moto g4 plus. I just want best battery backup.

    1. If you want better battery life phone why are you bothered about the camera, don’t under stand your loogik.

      1. logic is simple bro, I want best battery life, but just for bonus I want to confirm that it has better camera than 3s prime. I rarely use camera but to take pics of some book pages for study purpose I shoot, I also used yuphoria and it has really great camera pics were so sharp and accurate for me all we know rn4 has best battery but doubt about camera.

        1. Don’t buy RN4 if camera is your priority. It has really poor camera…. You can consider Nubia N1 for good camera, battery and music….Also if u r brand conscious then Samsung On8 as it juat got Rs.2000 price cut.

          I m using both the above phones. Please note that these phones are not for those who are heavy game users…

  22. How much free ram available on first boot in 2gb ram variant.
    Please do a comparison between all 3 models

  23. Gogi ji I have received Redmi Note 4 from mi.com but its showing Battery capacity as 4000 aAmp where as your review as well as mi.com says its 4100 mAmp. Why is it so?

    Anyone else also facing the same problem?

  24. Gogi sir does RN4 having hardware which supports less LTE bands as compared to RN3 or other 4G smartphones which may create problem in future for network support. .

  25. Hi Gogi bhai,

    Do you think, camera issue is with only made in China handsets, as compared to ones made in India

      1. pls confirm that thing if possible..also need to know about camera quality of 32gb/64gb and made in India/China handset.
