Alleged Redmi K100 Ultra tipped to feature 2nm chipset, 10,000mAh battery

Redmi could be preparing another flagship for its K100 lineup, and battery life appears to be one of its biggest priorities. An engineering sample of a new sub-brand flagship is reportedly being tested with a 2nm chipset and a battery of around 10,000mAh. While the tipster hasn’t named the device, it is being linked to the purported Redmi K100 Ultra, which could fill the gap for a dedicated gaming flagship in the current lineup.

Redmi K100 Ultra specifications tipped

According to tipster Digital Chat Station on Weibo, the engineering sample packs a custom single-cell battery with a capacity of around 10,000mAh. It reportedly supports 100W wired charging and 50W wireless charging, along with low-voltage discharge and global bypass charging. The latter allows the phone to draw power directly from the adapter during heavy use, reducing battery stress and heat during extended gaming sessions.

The battery capacity would match the standard Redmi K100, which already packs a 10,000mAh cell with 100W wired charging. However, wireless charging is a notable addition, as Redmi has reserved 50W wireless charging for the K100 Pro and Pro Max so far.

The same tipster previously reported that the device is testing a 50MP periscope camera with a 1/1.95-inch sensor and around 3x optical zoom. This would be a notable upgrade over the Redmi K90 Ultra, which has a 50MP primary camera and an 8MP ultrawide sensor but no dedicated telephoto camera. The chipset hasn’t been identified, although the leak points to a 2nm manufacturing process.

Redmi launched the K100 Pro and K100 Pro Max in August, followed by the standard K100 in October. The lineup already covers different priorities, with the Pro Max offering a 200MP main camera and 5x periscope zoom, while the standard model puts its 10,000mAh battery ahead of camera versatility. The purported Ultra could combine the larger battery with a dedicated gaming focus and wireless charging. Its 2nm chipset would also put it among the next generation of flagship performers, although the actual processor and gaming hardware remain unknown.

However, global availability remains questionable as usual. Xiaomi has brought the K100 Pro and Pro Max to international markets as the POCO F9 Pro and F9 Ultra, respectively. However, their batteries were reduced to 6,330mAh and 8,050mAh from the Chinese models’ 8,580mAh and 9,070mAh capacities. If the K100 Ultra follows the same route, international buyers may not get the full 10,000mAh battery. Those considering a gaming flagship may want to wait for confirmation, particularly if battery capacity is a priority.
