With a weight of just 155 grams, it is light enough for prolonged use without causing fatigue. The device flaunts a premium design with a glass front and back protected by Corning Gorilla Glass 5, and an aluminum frame enhancing its durability and providing a solid grip. It supports Dual SIM (Nano-SIM, dual stand-by), adding to its versatility in connectivity options.

Display

The Mi 9 SE boasts a 5.97-inch Super AMOLED display that supports HDR, which ensures vibrant colors and deep blacks, thereby enhancing the viewing experience. This display size is optimal for one-handed use while still providing ample screen space for media consumption and productivity tasks. With a resolution of 1080 x 2340 pixels and an impressive ~432 ppi density, the display is sharp and clear, perfect for high-definition content. The screen-to-body ratio stands at approximately 84.1%, providing an immersive viewing experience.

Performance and Software

Under the hood, the Xiaomi Mi 9 SE is powered by the Qualcomm SDM712 Snapdragon 712 chipset, manufactured on a 10 nm process. This octa-core processor, coupled with an Adreno 616 GPU, ensures smooth performance for everyday tasks and graphic-intensive applications. The phone was originally launched with Android 9.0 (Pie) and is upgradable to Android 11 with MIUI 12.5, offering the latest features and security updates. The user interface is intuitive, and the device runs efficiently, thanks to MIUI's optimizations.

Memory and Storage

The device is equipped with 6GB of RAM, which is sufficient for multitasking and running demanding applications without lag. In terms of storage, the Mi 9 SE offers two variants: 64GB and 128GB. While the storage capacity is generous, it is important to note that there is no card slot for expandable storage. This requires users to manage their storage wisely or utilize cloud services for additional space.

Camera Capabilities

The Xiaomi Mi 9 SE features a versatile triple-camera setup on the rear. The primary sensor is a 48 MP wide lens with an f/1.8 aperture, ensuring adequate light intake for sharp and detailed photographs. It is complemented by an 8 MP telephoto lens with 2x optical zoom and a 13 MP ultrawide lens, offering a range of shooting options. The camera system supports Dual-LED flash, HDR, and panorama modes, catering to a variety of photographic needs. For video recording, the rear camera can capture 4K footage at 30fps, as well as slow-motion videos at 720p up to 960fps with gyro-EIS. The selfie camera is a 20 MP sensor with an f/2.0 aperture, capable of recording 1080p videos at 30fps, perfect for selfies and video calls.

Battery and Charging

The Mi 9 SE is equipped with a Li-Po 3070 mAh non-removable battery. While the capacity may seem moderate, the efficiency of the Snapdragon 712 chipset and optimizations within MIUI ensure a decent battery life, with an endurance rating of 73 hours. For charging, the device supports 18W wired charging, which is fast enough to power the device quickly, reducing downtime significantly.

Connectivity and Other Features

Connectivity options on the Mi 9 SE are comprehensive. It supports GSM/CDMA/HSPA/LTE networks, making it versatile in different geographical locations. The device comes with Wi-Fi 802.11 a/b/g/n/ac, dual-band, Wi-Fi Direct, and DLNA for high-speed internet connectivity. Bluetooth 5.0 is onboard for seamless wireless communication, along with NFC and an infrared port, adding to its connectivity features. The USB Type-C 2.0 with OTG support allows for fast data transfer and charging.

In terms of sensors, the Mi 9 SE includes an under-display optical fingerprint sensor, accelerometer, gyro, and compass, enhancing the overall user experience. It lacks a 3.5mm headphone jack, which is a common trend in modern smartphones, but compensates with USB Type-C audio output and wireless audio support.

Price and Market Position

At the time of its release, the Xiaomi Mi 9 SE was priced around 460 EUR, positioning it as a mid-range smartphone. With its array of features, premium design, and robust performance, it offers great value for money, appealing to a wide range of consumers looking for an affordable device with flagship-like capabilities.
