Huawei is reportedly testing a smartphone with a battery capacity exceeding 10,000mAh, according to a tipster. The leak claims the company is using a new battery material and cell architecture to achieve the larger capacity. The technology may first appear in a mid-range model, possibly the Enjoy 100 series, before reaching flagship devices. Huawei's current largest battery is an 8,500mAh unit in the Enjoy 90 Pro Max. The company has not officially confirmed the development.
