GoKawiilChinese Android maker reportedly testing steel-cased batteries for 9,000-10,000mAh capacity
Leaker Digital Chat Station claims a major Chinese smartphone brand, likely Xiaomi, is testing steel-shell battery casings combined with stacked-cell manufacturing to boost energy density. The approach mirrors Apple's shift to rigid metal battery enclosures, seen in the iPhone 16 Pro and reportedly continuing in the iPhone 18 Pro Max, which is said to have a rated capacity around 5,391mAh. The goal, per the leak, is flagship phones with 9,000mAh to 10,000mAh batteries.
