An edge-to-edge Infinity-O notch is present, which has a camera in its top-right.

These options really enhance watching movies, pictures, videos, and playing games. The large screen of 6.39’ is safeguarded by the Gorilla Glass 6 – the latest and damage-resistant protector for smartphones.

As the brightness levels can go very high to about 620 nits, the display of MI 9 is easily visible in bright sunlight, and there is no difficulty in using the mobile phone outdoors.

Xiaomi Mi 9:

The camera of the Xiaomi MI 9 is one the significant specification of this mobile as it comes with a three-camera setup at the rear and a single powerful selfie-camera. On the back of MI 9, three cameras of 48MP, 16 MP, and 12 MP helps in taking fancy pictures, which can be further accentuated by the use of AI Technology. On the front, 20MP is installed as a selfie-camera.

In daylight, pictures taken by MI 9 are incredibly vivid, color-corrected, and have great details and tones. However, for the images taken in low-light situations, the camera does not fare as well as expected. Even with night mode, pictures were not as detailed as they should have been from this smartphone.

Users have the option to take ultra-wide shots through the 16MP camera present at the back. This helps in taking pictures of a large number of objects; however, the quality of the picture suffers due to this feature. Making use of the 12MP camera, MI 9 can focus on objects very quickly, and blur the background appropriately. This feature helps in taking pictures according to today’s trend and make your photos beautiful. Though the auto-focus option works most of the time correctly, the users also have the option of manual focus. The front camera also captures good photos with precise colours and brightness.

The rear camera supports 4K recording, which is really beneficial for people who depend mainly on their smartphones for heavy recording. With image stabilization, 4K video recording gives a very high-quality video.

Samsung S10:

Like its successor, Galaxy S10+, the rear cameras of the S10 also takes amazing pictures with the help of a 12MP primary camera, 16 MP ultra-wide sensor, and a 12MP camera that supports optical zooming. Capability to shoot high standard videos of 4K and HDR10+ is also present in Samsung S10.

The addition of an Instagram Mode is also bound to impress the users as through this mode, users can capture the photos enhanced for Instagram, and can easily share them to the social media platform.

Overall, the quality of the images captured and videos recorded is excellent from both the front and rear cameras. Moreover, pictures taken in different conditions like daylight, low-light, and indoors, are equally noteworthy, and various modes are already present in the camera app to enhance the images.


Xiaomi Mi 9:

The traditional mono speaker is installed at the bottom of Xiaomi MI 9, which is quite disappointing in this price range. Yet, a single speaker, along with an active external amplifier, gives a decently loud volume with perfect clarity.

Sound through the headphones delivers the excellent output with loudness being good and the clarity and the richness of the sound being nearly perfect.

Samsung S10:

The stereo speaker setup is present in Samsung Galaxy S10, which is capable of providing a very loud as well as crisp sound. On testing the speakers, S10 gets more decibels than most of its competitors.

The clarity of the sound output is great, and it also excels in terms of loudness and richness of the sounds. Audio through the headphone is equally impressive, but a very slight increase in crosstalk may produce a little distortion in the voice. Overall, the sound quality of the Samsung S10 is great.


Xiaomi Mi 9:

Xiaomi MI 9 is powered by Snapdragon 855 – a revolutionary modern chipset. This powerful processor is supported by the massive RAM of 6GB. The smartphone runs smoothly, and heavy applications and games like PUBG can be played at their highest graphics settings without any lag. On benchmark test, MI 9 scores very high on the chart, with the scores being as near as the 10,500.

The one problem that the users may face in the performance of this mobile is overheating as MI 9 sometimes get overheated while playing heavy games for long hours, watching movies, or even using light applications like the camera. Hopefully, this issue will be resolved through an update in the future.

Samsung S10:

Samsung S10 is available in two versions. One is driven by the Exynos 9820 (Europe variant), and the other one is powered by Snapdragon 855 (USA variant). Both of these variants make use of 8GB of RAM, which provides fast and impressive performance.

There are no lags in browsing, streaming, or gaming, thanks to its powerful processor.

Exynos version of S10, in particular, is highly impressive as it is one of the first smartphones to use this chipset, and it does it well by showing that the processor is able to handle any kind of game and applications without any type of problems.


Xiaomi Mi 9:

In Xiaomi MI 9, MIUI 10 launcher has been used based on the Android Pie. Overall, the software of the smartphone looks terrific as it provides customization options along with the in-built themes. New system icons, volume sliders, and shortcuts make the software of MI 9 user-friendly and easy-to-use.

Navigation options are present, which include swipe for home, recently-used application, and swipe and hold to return to the last app. These gestures work smoothly and support different features of the mobile by making them easily accessible.

Like the previous MIUI software, dark mode is present in MIUI 10 as well; but, a new variant of the dark mode is introduced in MI 9 as transforms the colors of the whole system to black to save battery. The compatibility of this mode varies from application to application. The software comes with live applications that switch automatically depending on the time of the day.

Samsung S10:

Samsung S10 has not introduced anything innovative in terms of the software it uses as it runs on the Android 9 and Samsung One UI. Other than the minor updates, two key features have been: Bixby Routines and Digital Wellbeing.

The object of the Digital Wellbeing is to limit the usage of the mobile to prevent phone addiction. Bixby is the management tool for Samsung S10 users to manage the necessary actions and tasks of the smartphone.


Xiaomi Mi 9:

A battery of 3,330 mAh is disappointing in any smartphone, but considering the price range of Xiaomi MI 9, it is extremely unsatisfactory. With such powerful features and processing power, a small battery is a negative point for the MI 9 as a single charge can hardly last a full day. Even with typical usage, the battery decreased significantly. A small battery test of the mobile showed that the battery falls down 15% when a video is played at maximum brightness for 90 minutes.

On the bright side, MI 9 charged up rapidly. It took about 45 minutes to charge the smartphone from 0% to 90%. The remaining 10% charging took more time. Charging the mobile wirelessly is impressive as well.

Samsung S10:

Samsung Galaxy S10 is powered by a battery of 3.400 mAh, which is not much high for a flagship smartphone, but the claim of Samsung that the battery is capable of providing power for a whole day is valid to some extent. Upon testing, the battery of Samsung S10 decreased to 20% after a whole day usage, which consisted of music streaming, playing videos, using social media applications, browsing, and gaming.

Samsung S10 can be charged quickly. The feature that impresses the most in terms of charging and the battery is its wireless charging as it is swift and introduces a new feature of Wireless Power Share through which you can use the Samsung S10 itself as a charger for other wireless charging devices. Charging through Power Share is comparatively slow, but it provides a fantastic tool in case of emergency.


At a relatively low price, Xiaomi MI 9 is a clear choice between Samsung S10 and MI 9. This is because MI 9 makes use of the same processor – Snapdragon 855 – and provides lag-free performance, and yet its price is roughly half as the cost of Galaxy S10. While MI 9 lacks in features and quality by the camera, it excels in terms of performance and software usage. However, if you want to enjoy loud music, have a comparatively larger battery, and take better pictures, you should go for the Samsung S10.
