Xiaomi’s new Redmi phone lasts for three days on a single charge

Xiaomi’s Redmi Note 17 Pro Max houses a 9,210 mAh dual-cell silicon-carbon battery—the largest Xiaomi has placed in a European phone—and some markets receive a 10,000 mAh single-cell version. The battery’s 16% silicon content boosts energy density, enabling the device, which matches the size of an iPhone 17 Pro Max while being 8 g lighter and slightly thinner, to last up to three days on a single charge.
