Purported Redmi K100 Ultra may pack a 2nm chip, 10,000mAh battery and 100W charging

Reliable tipster Digital Chat Station has shared new details on a next-generation sub-brand flagship now being discussed as the purported Redmi K100 Ultra. The tipster did not name the model, and the notes come from an engineering sample still in testing. Redmi has not confirmed the phone or any of the claims.

Redmi K100 Ultra battery and charging details

In a post today, Digital Chat Station said an engineering sample of the 2nm flagship carries a battery of around 10,000mAh and supports 100W wired charging plus 50W wireless charging. The tipster also cited a custom single-cell battery, low-voltage discharge, and global bypass charging, which can power the phone from the adapter during heavy use.

That would be a step up from the Redmi K90 Ultra, which arrived in China on June 30 with an 8,550mAh cell, 100W wired charging, and no 50W wireless charging. A 10,000mAh pack is already used on the standard Redmi K100, so the Ultra line would mainly gain capacity and wireless charging.

Redmi K100 Ultra camera and what to expect

The same tipster offered an early look at the camera hardware on November 5, saying this 2nm flagship is testing a periscope camera with a 50-megapixel, 1/1.95-inch medium-size sensor and around 3x optical zoom. The rest of the camera setup was not listed, so those details remain unknown.

A dedicated periscope would be new for the Ultra line. The K90 Ultra uses a 50-megapixel Light Hunter 800 main camera with a 1/1.55-inch sensor and an 8-megapixel ultra-wide lens, with no telephoto camera. The 2nm chip itself has not been named.

The tipster’s “sub-brand flagship” wording is typically read as a Redmi phone, which is why this sample is tied to a purported K100 Ultra. The Redmi K100 Pro and K100 Pro Max launched in August, and the standard K100 followed in October, but a separate gaming flagship is still missing. Until Redmi confirms the name and specs, this should be treated as an early leak.

Would a 10,000mAh battery and a 3x periscope make you wait for the purported Redmi K100 Ultra, or do the current K100 models already cover what you need? Let us know in the comments below.
