Xiaomi’s sub-brand, Redmi, is gearing up for what could be one of the biggest mid-range smartphone launches of the year quite literally, in terms of battery size. According to recent leaks, the company is working on a mysterious device equipped with an enormous 8,500mAh battery. This puts it directly in competition with Honor, which has been aggressively marketing smartphones with high-capacity batteries in recent months.
This upcoming model is expected to combine massive battery life with a relatively slim profile, potentially redefining the balance between endurance and design in the mid-range smartphone segment.

A New Challenger in the Big-Battery Segment
The leak, shared by well-known Chinese tipster Digital Chat Station, reveals that the upcoming Redmi smartphone has already passed successful internal tests with an 8,500mAh battery. Interestingly, this battery size is reportedly equivalent to a 9,000mAh pack in terms of actual energy storage performance, thanks to optimizations in cell design and internal structure.
Honor, which recently launched the Honor X70 with an 8,300mAh battery, will now face fresh competition from Xiaomi’s aggressive push into the high-capacity battery space.
Self-Made Technical Solutions
One of the most intriguing aspects of the leak is the mention of “self-made technical solutions” by Xiaomi. While details remain scarce, these proprietary innovations are aimed at increasing battery capacity without sacrificing longevity or charging cycles.
Large batteries often come with drawbacks, such as bulkier designs and reduced durability over time. However, Xiaomi appears to be addressing these issues through custom engineering, which could give the company an edge over competitors relying on more conventional battery designs.
Slim Design Despite Huge Battery
Packing an 8,500mAh battery into a smartphone is no small feat, especially when trying to keep the device slim. According to the leak, Xiaomi is working to keep the thickness of the device at just 8.5mm. For context, most smartphones with such large batteries tend to exceed 10mm in thickness, making them bulkier and less pocket-friendly.
If Xiaomi succeeds, this could set a new benchmark for large-battery smartphones in terms of ergonomics and portability.
Possible Model: Redmi Turbo 5 Pro
The leak has led many fans to speculate that this device could be the upcoming Redmi Turbo 5 Pro. Its predecessor, the Redmi Turbo 4 Pro, already made headlines with a massive 7,550mAh battery and 90W fast charging. If the new device indeed belongs to the Turbo series, we can expect even faster charging speeds, better thermal management, and improved efficiency.
This would align with Xiaomi’s strategy of using the Turbo lineup to push performance boundaries in the mid-range category.
Market Context and Competition
Most flagship smartphones from major brands still ship with batteries in the range of 4,500mAh to 5,000mAh. By contrast, Xiaomi’s upcoming mid-ranger would offer nearly double the capacity. This could be a major selling point for power users, travelers, and gamers who prioritize all-day usage without recharging.
Honor’s big-battery phones, such as the Honor X70 and Magic6 Ultimate Battery Edition, have already created a niche market for endurance-focused devices. However, Xiaomi’s established supply chain, aggressive pricing, and marketing reach could allow it to quickly capture a large share of this segment.
What We Know So Far
At present, there is no official confirmation from Xiaomi regarding the device’s name, specifications, or launch date. The leaked information focuses mainly on the battery and design, leaving details such as display type, chipset, camera configuration, and software features still under wraps.
Given the scale of the leak and Xiaomi’s recent emphasis on power efficiency, further announcements are expected in the coming weeks.
