There are rumors and a recent leak that mention that HONOR is working on a smartphone with a 12000mAh battery, along with a couple of devices with 10000mAh-class batteries.
HONOR 12000mAh Device and More
According to the leak, the company is working on four smartphones with 10000mAh-class batteries. This includes the 12000mAh battery device and one that is said to have a dual-cell 10000mAh battery design.
Both would set new records for the smartphone industry. The latter would offer the highest capacity for market-ready smartphones. Meanwhile, the latter would be the first device with a dual-cell design for a 10000mAh cell. This design could offer better heat management and charging efficiency, especially when partnered with 120W fast charging.

The leak, though, doesn’t reveal which series these devices will be a part of, meaning it could be the X-series, Power series, or WIN series. The latter two, if you’re unfamiliar, are HONOR smartphone series in China.
Currently, HONOR has the most devices in China that offer 10000mAh-class phones, with three of them available for users in China.
