Redmi's 12,000mAh Battery Enters Mass-Production Planning

A 12,000mAh battery cell intended for a Redmi smartphone has completed mass-production planning, according to a new leak.

The leak says the 12,000mAh cell is meant for a mid-to-high-end phone but does not name the model. It also claims Redmi is evaluating a roughly 13,000mAh to 14,000mAh cell that "could go into mass production next year, though it’s written in pencil." The 12,000mAh cell has finished mass-production planning but no model or launch date is named.

Redmi's battery push timeline

Redmi has increased its battery capacity rapidly over the past year. The Redmi Turbo 5 Max launched in January with a 9,000mAh battery. The Redmi K100 reached 10,000mAh by October and pairs that cell with 100W wired charging. The K100's 10,000mAh cell was tracked from an August leak to its official confirmation before the phone's October launch.

A 12,000mAh phone would add 3,000mAh to the Turbo 5 Max in under a year. Earlier leaks have suggested other large-capacity models are in development: more than 10,000mAh for a Redmi Turbo 6 Max and roughly 10,000mAh in a Redmi Note 17 Pro Max, according to reports. The new leak does not say whether the 12,000mAh cell belongs to either of those phones.

The leak provides no details on charging speed, thickness, weight, or price. For reference, the Redmi K100 starts at about $525 (CNY 3,499). Mass-production planning precedes a launch and does not set a date.

Availability is an open question. The Redmi K100 remains China-only and the company has given no indication of a global release; the unnamed 12,000mAh phone could follow the same pattern.
