Xiaomi Mi 9 hardware

Physically, the phone is a beauty to behold. However, there are other features that make it attractive on the outward.


Its holographic spectrum is responsible for the phone's funky look. To add to this, it comes in a variety of colours including blue and violet. The black colour makes the gadget shine even more. It is glossy and prone to fingerprints and smudges. For more options, the phone comes with a transparent alternative too.

You can pick from any of the colours including the Piano Black, Ocean Blue, and Lavender Violet, as well as in faux Transparent. You can go for the blue and violet variations which have a nice gradient at the back. The Piano Black may seem boring but it is still a great looker. The transparent one comes through with futuristic prospects.

The entire back of the phone comes with a Gorilla Glass 5 piece that bends towards the frame. The ups and downs of the rear curves make it appear thinner than it truly is. However, the grip suffers. The polished metal frame does not support grip but it helps enhance the look. It would be safe to say that Xiaomi chose to favour beauty in place of practicality as far as design is concerned.

Talking of display, the phone delivers exactly what it promises with its decent brightness. This is just perfect for an OLED panel of 430 nits. This can go up to the highs of 620 nits, especially when left on Auto.

The sunlight contrast on the phone is perfect as it delivers the best form of brightness expected of any AMOLED screen. Leaving it on Adaptive Contrast, which is the default, makes the phone change colour according to the surrounding light. The increased contrast mode gives a saturated look that boosts the reds and greens but also goes slow on the blues.

Processor, storage and performance

The phone comes with an internal storage capacity of either 64GB or 128GB. It is powered by a 2.84GHz octa-core Qualcomm Snapdragon 855 processor and has either 6GB or 8GB of RAM. When it comes to performance, the phone has been rated as one that delivers what it promises. Games run quite effectively on it, making it an attractive option for any person seeking to find an excellent quality phone at a low budget.

On gaming performance, it comes with the new Adreno 640 GPU that offers support to the Vulkan 1.1, HDR Gaming, as well as Physically Based Rendering. It is also expected to offer a reasonably good performance bump over the 630 with Snapdragon 845.


Xiaomi Mi 9 battery

There is a lot to say about the Xiaomi Mi 9 battery. First would be to note that the battery life depends on use. The gadget is powered by a rather modest 3,300mAh battery which is 100mAh less than the cell of its predecessor, the Mi 8. This can be considered as another low but with the support of both wired and wireless fast charging, the phone quickly redeems itself.

Onto the tricky part though, the charger. The phones come boxed with an 18W charger. This means that 45% of your charge can be depleted in half an hour. This would be sufficient for medium to low gadget users. If you are the kind that needs heavy usage of the device, probably because you must be online continuously, then at an extra 20 dollars, you can get yourself a faster charger.

Even so, with Mi 9 supporting the 27W wired as well as the 20W wireless charging known as Charge Turbo, things can be simplified. It is possible to access both goodies in the Xiaomi Mi 9 wireless charger bundle. While it is not possible to buy the pieces separately, the phone's general price makes it understandable. If you use the optional accessories and the boxed charger, it is possible to get your device to 70% charged in just 30 minutes which means that full charge will take a maximum of 65 minutes.

Speaker and call quality

While the sound may be questionable in some quarters, the phone comes with a linear speaker and an audio output that is amplified by Smart PA. One demerit that should be factored in is the fact that it has no 3.5mm headphone jack. With a little more consideration on the audio quality, this phone may have been near perfect, but then again, you cannot have everything.

An interesting guide to the amazing Xiaomi Mi 9 Pro 5G smartphone

It is true that a lot has changed from the previous version of the phone, but fans can relax knowing that the excellent speakers are still with us. While it is disappointing that the new phone lacks stereo booster speakers, it has excellent speakers whose loudness is unquestionable. When it comes to audio quality, the Xiaomi Mi 9 is rather impressive with the active external amplifier as it delivers an output rated at above-average loudness, not to mention the flawless clarity.


It is important to have great features and hardware components for a phone, but when it comes down to it, the software is just as crucial for a phone's excellence. Here are some of the software aspects that make the Xiaomi Mi 9 stand out.

OS and features

Without an excellent Operating System, the gadget is as good as dead. This phone runs on the latest MIUI 10 launcher on Android 9 Pie. The MIUI 10 is responsible for the system's enhanced looks, performance and gestures but still retains the MIUI logic. This means that any former user will feel at home. The same can, however, not be said for new users who will need some time to get the hang of it.

Users will also love the additions this new phone comes with, including native support for navigation gestures, Picture-In-Picture mode that is available in a few compatible applications, a brand new Recents menu -coming with useful gesture support, native autofill support, improved screen recording, enhanced AI, as well as better app management.

To all the mentioned enhancements and additions, add the ability to choose as many themes as you want as well as the always-on-display support.

Camera, video, and image quality

Making an entrant in the market as the first Xiaomi phone to have a triple camera, the main camera has 1/2" 48MP sensor behind f/1.75 lens on the back of the gadget which spits 12MP images. If you love photos, then the new Xiaomi Mi 9 camera will fascinate you. Apart from the main camera, there is the 12MP telephoto snapper that allows for 2x optical zoom, and a 16MP ultra-wide-angle shooter. It also has a Sony IMX586 48MP sensor that uses a Quad Bayer arrangement. This serves as a 12MP sensor with huge 1.6µm pixels as well as a real-time HDR. The 12MP telephoto shooter has 1.0µm pixels and f/2.2 lens.

Sony Xperia 5 review: the good and bad

The phone's 48MP sensor is located behind an f/1.75 lens. Not even one of the 3 snappers has optical stabilization. The third and final camera, which is the newest for the new Mi series, is an ultra-wide-angle 13mm 16MP snapper behind an f/2.2 lens. It comes with a few surprises of its own, considering that it is an ultra-wide camera yet it offers excellent autofocus.

The camera app remains still pretty much the same as it allows users to adjust for beautification and other reasons. On picture quality, the default wide-angle or 1x photos are from the 48MP sensor. Once the phone gets to work, the finished product is 12MP resolution. As long as you are not so much into artefacts, then you will love the fact that the photos showcase a lot of details, superb contrast, lively and accurate colours, impressive dynamic range, and generally excellent processing. The HDR effect could do much better though.

Exciting new details about the iPhone 11: prices, specs and how you can pre-order it

Clearly, there is a lot of excitement surrounding the phone.


The Xiaomi Mi 9 price confirms that indeed, this phone gives you value for money. It may not be perfect or a trendsetter as others before it but it is still a good phone. It comes through as an upgrade with several additions to enhance its effectiveness. It goes for around €500 in the European market. One may ask, does Xiaomi 9 work in USA? To answer this question, kimovil.com wrote:

...the ideal thing is that the Xiaomi Mi 9 has all the frequencies for all networks, that are used in USA, although if the Xiaomi Mi 9 lacks any of the frequency bands used, it does not mean that it does not work on that network, but coverage could be limited to certain areas.

Comparing it to other phones, the Huawei Mate 20 may be the closest in terms of features, considering it has a similar screen even though it is an IPS LCD type. The triple camera with Leica lens almost makes the two identical. With the Huawei also going for €500, it becomes a real threat here.
