Thanks to Oppomart for sending Xiaomi Redmi Note 4 for a review.

Xiaomi Redmi Note 4 Review: DESIGN and DISPLAY


The front of the phone looks just like previous Note-series devices. We have a sharp and bright 5.5” 1080p display, nicely backlit capacitive buttons and a highly customizable notification LED light.


However, once you pick the phone up, you can definitely notice that the Redmi Note 4 is much more solid and it is easily the best-constructed Redmi Note phone yet. It just feels that Xiaomi used a higher quality metal in the construction of the phone. Also, the top and bottom parts are made of aluminum too, not like previous models.


We have a 13MP shooter on the back, which is coupled with the dual-LED flash.

Xiaomi phones have been known for great fingerprint scanners and the Redmi Note 4 is no exception. You can unlock your phone very quickly straight from the standby mode.

The buttons feel nice and tactile, and we have an IR blaster to control devices like TVs.


Xiaomi decided to stick with the micro USB port on this phone. As for loudspeaker, I would say it is pretty good as on most of the Xiaomi phones. However, there is a little bit of distortion going on at the highest volume settings.


The sound quality via the headset jack is pretty good too.

Xiaomi Redmi Note 4 Review: HARDWARE and PERFORMANCE


I have a standard edition of Xiaomi Redmi Note 4 sports a deca-core Mediatek Helio X20 chip with the max. clock speeds of 2.1GHz, 2GB of RAM and 16GB of storage, which is also expandable via the microSD card slot.

If you are willing to pay extra, you can get a 64GB model with 3GB of RAM.

The gaming performance is great and the phone performs even better than the Redmi Pro despite having the same chip. Games like Asphalt 8 run fine on the highest graphics with just a few skipped frames but that didn’t bother me at all.


A great thing is that the phone does not have any overheating issues.

Xiaomi Redmi Note 4 Review: BENCHMARKS

Xiaomi Redmi Note 4 Review: USER INTERFACE

When it comes to the user interface, the Redmi Note 4 ships with the MIUI 8, which uses Android 6.0 as a foundation.

The MIUI looks similar to the older version but it also has some new design touches. For example, we have a redesigned quick settings and re-organized full settings menus. Now it is easier to find everything and the menu just looks cleaner.

As usual, there are plenty of customization options Xiaomi phones have been famous for. Just to name a few, you can adjust display settings, choose from a variety of themes and so on. One of the key features is called second space. In each space, you can have your different accounts, apps and so on, and you can easily switch from one space to another.

Most importantly, the phone has been working fine and I didn’t have any lag.

Xiaomi Redmi Note 4 Review: CAMERA

We have a familiar camera app that allows you to take pictures very fast and play with some basic shooting modes and settings.

Xiaomi Redmi Note 4 Review: IMAGE QUALITY

The 13MP camera produces images that are comparable to the Redmi Note 3’s camera but I think we need to see a software update to make the best out of the camera sensor.

For a $160 phone, the pictures look quite nice and there is a good amount of detail in most of the daylight shots. However, there were a few pictures with softer focus and inaccurate-looking colors, especially if you take pictures indoors.

When it comes to the low-light photography, the Redmi Note 4 is a pretty good performer. Sure, you can’t expect much from a $160 phone but the images are one of the best in class.

The video quality is pretty good but it could definitely have more detail and look sharper.

As for selfie camera, a 5MP shooter can produce quite good selfies that will be more than enough for social media.

Unfortunately, the stock camera app allows you to shoot only in 720p with the front facing camera. On the other hand, the quality of the footage is pretty good.

Xiaomi Redmi Note 4 Review: CONNECTIVITY


The phone comes with a hybrid dual-SIM card tray, which can take either 2 SIMs or 1 SIM and the microSD card.

As for connectivity, everything has been working fine. Once I first got the device, the Wifi download speeds were very slow but the software update has already fixed that, so make sure your phone runs on the latest version of the MIUI.

Xiaomi Redmi Note 4 Review: BATTERY LIFE


A huge 4100mAh battery has been phenomenal. I could use the phone for 2 days easily even with some heavy usage and I used the phone with the performance mode turned on all the time.

That translates to over 5 hours of screen-on time. If you are a lighter user, you can easily get over 6 or 7 hours of SOT.

Although the Note 4 uses MediaTek PumpExpress 2.0 technology for fast charging, Xiaomi does not include the fast charger in the box.

Xiaomi Redmi Note 4 Review: CONCLUSIONS


Xiaomi Redmi Note 4 is yet another budget offering by the Chinese giant and I have to say that it is a great phone for the price of $160.


The device sports a very good built quality and it uses metal in the construction. Also, we have one of the best-in-class display, feature-rich user interface and the phone can handle 3D games quite well. Finally, the battery life is fantastic. Even though I got just over 5 hours of screen-on time, I’ve seen some moderate users achieve over 7 hours of SOT.


On the other hand, the rear camera does not seem to have been upgraded. In fact, the current software build leads to a slightly worse performance than the Redmi Note 3 but knowing Xiaomi, it will be definitely fixed with a software update.


The question is: should you upgrade if you have the Redmi Note 3. I would say no since this phone is just an incremental upgrade.


However, if you are in the market of a solid budget-friendly phone, the Xiaomi Redmi Note 4 should be definitely on your list as it is an easy buying recommendation for the price of under $160.

    • cheers! I hope to get that phone sooon

      • Muhammad Yasir

        please PLEASE linus focus on the dual camera bokeh effect and the faulty focus during video recording and soft focus when taking bokeh pics

      • Hirant

        Cheers Linus, thanks for the review of this redmi note 4. By the way, did you get in touch with Leeco Cool1 Dual yet? Did you start to test it. If you compare Cool1 with Redmi note 3 pro or Redmi Note 4, which one wins, in terms of speed, battery, camera? When are you going to release Thé Cool1 test results and review? Thanks.

  • bro-reac

    Thanks for the review. Which means we expect a Redmi Note 5 very soon since this was just an incremental upgrade.

    • We should expect the Redmi Note 5 once the Mediatek X30 chips hit smartphones

      • Muhammad Yasir

        I WANT REDMI NOTE 5 !

        • Mr.Flying Zoom3rz

          But I want RN4 Snapdragon edition…:( 4GB+SD820 pls hah lmao

          • Muhammad Yasir

  • mf1gt3r

    Nice review.

  • Raky_b

    just 5h of SOT???
    that much i had with SGS3…and than i have moved to chinese phones, and never achived that again.

    • that’s on the heavy use. it’s a very good result. I had my GS3 long time ago and with my usage I could barely get 2 hours of SOT

  • AtereJr

    I have to say…. the rear design looks better than on previous Redmi models.
    The Mi5s should better feature some metal.

  • Jiraya Ziane

    i expect more for the camera

  • Wolvie

    Samsung galaxy note 7 is better as it came built in with TIME BOMB literally LOL

    • bro-reac

      Was built by a terrorist group. LOL……

      • Muhammad Yasir


    • Muhammad Yasir

      lol … innovators way ahead of their time

  • Jason Joshua Tauro

    Hopefully they release a snapdragon variant again. Mediatek devices should be avoided.

  • Rick Flair

    Is this better than the RN3 Pro Linus? my girlfriend was getting up to 9 hours SOT with the RN3 Pro with Cyanogenmod 13

    • Mr.Flying Zoom3rz

      In terms of performance no, in terms of battery life again RN3P is proven to be better. Remember the battery life difference between RN3 and RN3P? I doubt the X20 can match the efficiency of SD650.

  • Jon Michael Chua

    Linus, is the front camera wide or no difference with other Redmi notes? If not wide, any Chinese phones with wide front camera?

  • Great read. Thanks!

  • Sathish

    Linus, Does it have Quick Charge? How long is it taking to full charge the battery

  • Muhammad Yasir

    @disqus_zVM1xgVozO:disqus … you say that the Redmi note 4 has a GREAT camera for the price and is VERY decent EVEN in low light. then why did u rate it 3.5 out of 5 ?

    this is confusing !

    • Mr.Flying Zoom3rz

      Bro…It’s great for a budget phone you know… Linus probably have seen much better cameras..that’s why it’s 3.5/5 But for the price yeah it’s great.

      • Muhammad Yasir

        then i want one !

        too bad they’re banned in Pakistan. would’ve purchased one in a heartbeat

  • Najib Ar-Rahman

    Hi, need some valuable suggestions.

    I’ve shortlisted the following phones for purchase:

    Xiaomi Redmi Note 4 64GB $210
    Xiaomi Redmi Pro 64GB $250
    Xiaomi Mi5 32Gb $275
    Vivo V3 Max $300

    Which would be the best? (I’m also considering the Huawei Nova Plus but its too expensive at $375)

    P/S: Priority is Design, Camera & Battery Life.
