Redmi has reportedly completed mass-production planning for a 12,000mAh smartphone battery, signaling another major step in the capacity race among Chinese phone makers. The cell is expected to appear in an as-yet-unnamed Redmi handset positioned between the midrange and premium segments.
The report also says Redmi is evaluating an even larger battery in the 13,000mAh-to-14,000mAh range for possible production in 2027. That project is still under consideration, however, and no final decision has reportedly been made.
Redmi has rapidly increased battery capacity across its recent lineup, although it remains unclear which future model would receive the 12,000mAh pack.
- Redmi Turbo 5 Max: launched in January 2026 with a 9,000mAh battery, then the brand’s largest phone battery.
- Redmi K100: introduced in October 2026 with a 10,000mAh battery and 100W fast charging.
- Redmi Turbo 6 Max: rumored to use a battery of around 10,000mAh or more, but it has not been confirmed as the destination for the 12,000mAh cell.
Redmi would join a growing push toward ultra-high-capacity batteries. OPPO is also reported to be developing a 12,000mAh model, while Honor already has a phone with a battery at that capacity. Redmi has not confirmed the 12,000mAh handset, its name, charging specifications or launch markets, leaving the key question as to which model will carry the cell first.
