Xiaomi Mi 9 Review | Without a doubt, this is Xiaomi’s best.

Here is the Xiaomi Mi 9.  The Xiaomi flagship smartphone model for 2019 and right off the bat, I can tell you this is without a doubt their best phone yet, even though it still has a couple of minor issues. So let’s jump right into it, I’ve been using this Xiaomi Mi 9 for quite some time and I came to the conclusion that there is a certain number of points that are good and points that can be improved on.

I will start with those points that can be improved on because I have the feeling that many other reviewers are neglecting these. Before anything else, the Xiaomi Mi 9 has an impressive price/quality ratio and while not everything is perfect yet, I think if you consider this device, you want to get the most bang for your buck.

Areas That Needs To Be Improved In The Xiaomi Mi 9.


The Xiaomi Mi 9 Battery.

Xiaomi definitely had to make some trade-offs and I understand that, but still, the Xiaomi Mi 9 has a 100 million power battery smaller than its predecessor to Mi 8, on top of that the 3300 milliamp-hour battery isn’t considered a large one for 2019 standards at least that’s for me.

Regarding the battery life itself, the Mi 9 will get you through the day, but I didn’t manage to get two full days out of it and I normally get around 6 to 7 hours of on-screen time which is not exactly on par with other high-end flagship models.

 The Xiaomi Mi 9 Camera. 

The Xiaomi Mi 9 still didn’t manage to put electronic image stabilization or any kind of stabilization in the front camera while many other competitors do so.

The camera is 20 megapixels so it could even record in 4k video and therefore it can be a little bit cropped for the electronic image stabilization and bump up the resolution at the same time. On top of that, the focus is fixed which can be very annoying at times so you need to find the sweet spot yourself.

On the rear cameras, there’s no longer optical image stabilization which is for me the perfect combination with electronic image stabilization, it’s just perfect for the smoothest footage. The electronic image stabilization does a good job but while bending it looks to jitter or to skip every once in a while view a couple of frames.

You will notice a huge camera bump at the rear, It protrudes a lot and even it sticks out from the provided case and I personally wouldn’t mind having a slightly thicker phone with no camera bump.


Xiaomi Mi 9 Audio.

The audio is, with the front and with the rear camera, poor. That’s mainly because of its low bitrate and thus it results in audio that could be a whole lot better and also it could be quite easily improved by Xiaomi by a software update.

Xiaomi did find space for a third camera but didn’t have space to return the 3.5-millimetre headphone jack which is kind of strange for me. Also, there’s no longer a microSD card slot anymore and even though there are two speakers there’s just no stereo effect.

Last but not least, for the price, it’s almost impossible to add an IP rating which is on one hand very expensive and it’ll make the device a whole lot more expensive as well.

Xiaomi did take some precautions with your rubber ring around the SIM tray but keep in mind that it might not be waterproof and nope I’m not gonna try that out I like my Mi 9 and I just don’t wanna risk it.

The Good Aspect Of The Xiaomi Mi 9.

Yes, I might be nitpicking a little bit over here and mainly on the camera. I think that Xiaomi improved a lot over the last couple of years but those are just a couple of points that could be improved relatively easily with a software update. Other than that, there’s an even amount of good points and I think that the Xiaomi Mi 9 is definitely worth its money.

Xiaomi Mi 9 Display

Xiaomi installed an amazing display and probably the best one they could get their hands on. It might be only a 1080p panel with 60 Hertz and MLA type but it’s a really good one. It has vibrant colours, good figuring angles and deep blacks of course and if you enable the outer brightness it will go up to 620 nits of brightness which is perfect for outdoor usage.

The left button is a mappable button and by default, it will open Google assistant but it’s possible to configure it yourself as well, meaning you can set it to open the camera application for example.

The Camera Good Aspect.

I’ve been nitpicking on the camera, but to be honest it’s actually a pretty good one with normal lighting conditions. Photos come out very nice and the 48 megapixels photos are nicely processed to 12 megapixels and they’re still plenty of detail and impressive dynamic range, vibrant and accurate colours, great contrast and overall just very nicely processed images.

It is also very good to see that they added a wide-angle lens and that is my favourite one of the three because of the new perspective that it offers you. You will see soft corners with some chromatic aberrations but it’s very well minutes and they also allow you to turn on or off this option for distortion correction which is a very warm welcome.

For the portrait pictures, the telephoto lens is used by default. I personally prefer the main sensor for a full-body shot. The edge detection is great and one of the best that I’ve seen and it’s also nice that Xiaomi allows you to adjust the blur intensity.

Also, filming in 4k is also a pleasure except for the padding issue of course as mentioned before but the footage is really smooth and very vibrant.

Camera Quality

The FingerPrint Scanner

Like any other kind of high-end flagship smartphone from 2019, the fingerprint scanner is located under the display. The fingerprint scanner is fast and reliable, but not as fast as the traditional scanners. The development is going fast currently.


Xiaomi also updated their DRM level to one in order to watch Netflix for example in Full HD and I think that a lot of you will appreciate it, or at least I appreciated that I can watch series and just content that I’m streaming in Full HD.


The Xiaomi me 9 feels really smooth there’s no jitters or stutters. Even though the MIUI 10 is a heavily modified skin, it is still super smooth and easy to use. It works just great and I really like that they’ve added the dark mode feature to turn almost everything that’s white into black to save even more battery.

The OS on display received an update and now it’s possible to schedule it and there are several themes to choose from or to customize it completely yourself.

So besides that, the device feels super smooth and it is also super fast and playing games are really enjoyable especially on the highest settings. It is possible to play without any kind of stutters or skip frames and prop D, for example, runs incredibly on your highest settings possible and the device is not getting uncomfortably warm.

Charging the Xiaomi Mi 9 is also super fast, it comes with a charger that gets the job done in one hour and 25 minutes but it’s also possible to get the quick charge for the charger which charges the phone in 65 minutes which is even faster of course. On top of that, it’s also really nice to see that Xiaomi added the wireless charging feature with up to 20W support.


Now last but not least, I believe that Xiaomi has an amazing price-quality ratio and that you can get more bang for your buck with this new flagship model for 2019.

I think that you now have a lot of information with all the good points and all the points that they still need to improve on which is much software related to some over-the-air updates and Xiaomi has a really good track record for that so I think it’s just a matter of time until they solve these little issues and make it an even more interesting phone.

If you decide to purchase the Mi 9, it comes in a super shiny box I’m not sure if you can see it but believe me it is super shiny, at the bottom of the box you will find the 18W EU power plug adapter and the type-c cable.

There it is the Xiaomi Mi 9, a really well-built phone that looks and feels luxurious although it has a huge camera bump.
