A fresh leak is shedding light on several upcoming Xiaomi devices, focusing mainly on battery and charging specs. The available information points not only to the Xiaomi 17T, but also to the POCO X8 Pro and the higher-end POCO X8 Pro Max. All three models appear to prioritize battery capacity, with the POCO pair standing out the most. Obviously, for the mass market, the POCO X8 Pro Max should be the most anticipated device, since it will likely serve as a direct replacement for the POCO X7 Pro.

POCO X8 Pro Max battery details surface

According to supply chain sources and code analysis shared by PaperKing13, the POCO X8 Pro Max will feature a massive 8,500mAh battery. That would make it one of the largest batteries ever used in a POCO smartphone. Despite the huge capacity, the device is still expected to support 100W wired fast charging, allowing for much faster top-ups than typical large-battery phones.

The phone will boast a massive 8,500mAh cell, making it a big deal for those who enjoy long endurance. It will be the perfect device for mobile gamers, considering this could be paired with the Dimensity 9500s SoC.

Link to Redmi Turbo 5 Max

The POCO X8 Pro Max is rumored to be a rebranded Redmi Turbo 5 Max for global markets. The Turbo 5 Max recently launched in China and reportedly comes with an even larger 9,000mAh battery. The slight reduction to 8,500mAh on the POCO model could be related to regional certification rules or safety requirements. Even with that adjustment, the battery size remains far above what most smartphones offer. For comparison, the current POCO X7 Pro has a 6,000mAh battery across global markets and 6550mAh in India.

POCO X8 Pro also focuses on battery

The standard POCO X8 Pro will reportedly carry a smaller, but still large, 6,500mAh battery. Just like the Max version, it is expected to support 100W wired charging. This keeps fast charging consistent across the lineup while separating the two models mainly by battery capacity.

Recent certification listings have also revealed the POCO X8 Pro in multiple markets, suggesting a broader global launch is in preparation. In addition, a special POCO X8 Pro Iron Man Edition is said to be in development, indicating Xiaomi may also push themed variants alongside the regular models. This particular version is expected to come with the new Dimensity 8500 Ultra.
