About the Xiaomi Poco X8 Pro Max

The Poco X8 Pro Max is a mid-range powerhouse that pushes the boundaries of what you should expect from a phone under £500. At its heart is the MediaTek Dimensity 9500s, a flagship-tier 3nm chipset that delivers top-end performance for gaming, multitasking, and demanding apps. The 6.83-inch QHD+ AMOLED display is genuinely stunning, with 3,500 nits peak brightness, HDR10+ support, and a 120Hz refresh rate that makes everything from streaming to scrolling feel incredibly smooth. The real headline is the colossal 8,500mAh silicon-carbon battery, one of the largest ever fitted in a mainstream smartphone, paired with 100W HyperCharge and 27W reverse charging. Poco has wrapped all this in an aluminium frame with a glass back and the highest possible IP69K water and dust resistance, meaning it can withstand high-pressure water jets. The 50MP main camera with OIS and a large f/1.5 aperture captures solid photos, while the 8MP ultrawide adds flexibility. Starting at £359 in the UK, the X8 Pro Max offers a level of endurance, performance, and build quality that makes many flagship phones look overpriced.

Frequently Asked Questions

Is the Poco X8 Pro Max worth buying?
The Poco X8 Pro Max is one of the best value mid-range phones available. Its Dimensity 9500s chipset delivers genuine flagship performance, the 8,500mAh battery is in a league of its own, and the QHD+ AMOLED display is exceptional for the price. If you want a phone that outlasts everything else on the market, it is hard to beat.
How good is the Poco X8 Pro Max camera?
The 50MP main camera with OIS and a fast f/1.5 aperture using the Light Fusion 600 sensor produces detailed, well-exposed photos in both good and moderate lighting. The 8MP ultrawide handles wider scenes, though it is not as sharp as the main sensor. For the price, the camera system is competitive, though dedicated camera phones from Samsung or Google offer more versatility.
How long does the Poco X8 Pro Max battery last?
The 8,500mAh battery is one of the largest in any smartphone, comfortably lasting two full days of moderate use. Even heavy users including gamers should get well over a day. The 100W HyperCharge reaches 50% in just 24 minutes, and 27W reverse charging lets you power other devices.
Is the Poco X8 Pro Max good for gaming?
Excellent. The Dimensity 9500s with its Cortex-X925 prime core and Immortalis-G925 GPU handles demanding games at high settings with smooth frame rates. Combined with the 120Hz QHD+ display, stereo speakers, and the enormous battery that will not die mid-session, it is one of the best gaming phones under £500.
Is the Poco X8 Pro Max waterproof?
The Poco X8 Pro Max has the highest possible IP69K rating, meaning it can withstand high-pressure, high-temperature water jets as well as full submersion. This makes it one of the most water-resistant phones available at any price, far exceeding the IP68 rating found on most flagships.
How does the Poco X8 Pro Max compare to the Poco X8 Pro?
The X8 Pro Max upgrades to a flagship Dimensity 9500s chipset from the X8 Pro's Dimensity 8500 Ultra, jumps to a QHD+ display from 1.5K, increases the battery from 6,500mAh to a massive 8,500mAh, and adds 27W reverse charging and IP69K water resistance. The X8 Pro remains a solid choice at a lower price if you do not need the extra power and endurance. Compare Poco X8 Pro deals.

Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
