A little over a year after the Poco X7 series, the X8 models are following: In addition to the X8 Pro Max and the X8 Pro, there is an Iron Man edition, as with the predecessor. The devices cost between 400 and 550 Euros.

The Poco X8 Pro Max is powered by a MediaTek Dimensity 9500s chip, which is one level below the Taiwanese semiconductor developer's top chip. The Dimensity 9500s is manufactured using a 3-nanometer process and is an octa-core chip. The Immortalis-G925 GPU is responsible for graphics, and the MediaTek NPU 890 is responsible for AI acceleration. The X8 Pro, on the other hand, features a Dimensity 8500 Ultra (4nm) with a Mali-G720 MC8 GPU.

The Pro Max comes with 12 GB LPDDR5X RAM (9600Mbps) and 256 or 512 GB of fast UFS 4.1 storage. Xiaomi offers the 201-gram X8 Pro with DDR5X and UFS 4.1 in storage combinations of 8GB+256GB, 8GB+512GB, and 12GB+512GB.

The Poco X8 Pro Max features a 6.83-inch AMOLED screen with a resolution of 2772 x 1280 pixels and support for a refresh rate of up to 120 Hertz. It can reach up to 2000 cd/m² in High Brightness Mode (HBM) and a peak of up to 3500 cd/m² in specific areas. At 6.56 inches, the screen of the X8 Pro is slightly smaller, but according to the manufacturer, it is just as bright as that of the Pro Max. Both screens are protected by Corning's mid-range protective glass, Gorilla Glass 7i.

The X8 Pro Max contains a massive 8500 mAh battery, which according to the manufacturer can deliver two days of battery life. The device is charged wired with up to 100 W, and it can also charge other devices with up to 27 W via reverse charging using a USB-C cable. The X8 Pro has "only" a 6500 mAh battery, which can charge and share power just as quickly as the Pro Max model. Both devices are protected against the ingress of dust and water according to IP68.

In terms of the cameras used, the Poco models should not be compared to the Xiaomi 17 series, which was developed with Leica. This is because both variants feature a 50-megapixel main camera with a large f/1.5 aperture – however, in the 218-gram Pro Max, Xiaomi uses a Light Fusion 600 sensor, and in the Pro, a Sony sensor of type IMX882, which was already found in the X7 Pro. Both also have an 8-megapixel ultra-wide-angle lens, and a 20-megapixel front camera is located on the front.

Further features of the devices include Wi-Fi 7 in the Pro Max and Wi-Fi 6 in the Pro, as well as Bluetooth 6 and Xiaomi's "Offline Communication", which essentially turns the devices into walkie-talkies. This function premiered in the Xiaomi 15T. It uses optimized Bluetooth peer-to-peer technology for connections over distances of up to 1.9 km in open terrain.

Like all current Xiaomi models, Poco's X8 Pro series is also powered by Xiaomi HyperOS 3. Google Gemini and Circle to Search are on board. Xiaomi promises four years of Android updates and six years of security patches for the two models. In essence, less than what the EU requires with the Ecodesign Regulation since June 2025, however, manufacturers use a "loophole" in the wording of the text that implies voluntariness. Unfortunately, this loophole is exploited by many manufacturers.

The Poco X8 Pro Max is available in three colors: Black, White, and Blue, and in two storage variants. It costs from 529.90 Euros. The X8 Pro is offered in three colors: Black, White, and Mint Green, and in three storage variants. Prices start at 399.90 Euros. The "Poco X8 Pro - Iron Man Edition" is available in the 12 GB + 512 GB variant for 549.90 Euros. The Iron Man Edition differs from the X8 Pro only in terms of design: it is visually inspired by Tony Stark's black and gold armor, with the lightning bolt symbolizing the Arc Reactor in the center, according to Xiaomi.
