Xiaomi’s new Redmi phone lasts for three days on a single charge
Xiaomi has launched the Redmi Note 17 Pro Max, whose 9,210mAh battery is the largest it has put in a phone sold in Europe. The company says the silicon-carbon battery can provide up to three days of typical use, making extended battery life the handset’s main selling point despite some more modest specifications.
In some markets, the phone has an even larger 10,000mAh battery; Xiaomi claims 37 hours of video playback, 80% capacity retention after 1,600 charging cycles, and full charging in just over an hour with 100W wired charging. It has a Snapdragon 6 Gen 5 chip, up to 12GB of RAM, a 6.83-inch OLED display and IP69K protection, but relatively basic cameras; it will cost about $499 outside the US.

Xiaomi is a Chinese electronics company that sells phones under its Redmi brand, including the Note series. Battery size, measured in milliamp-hours, gives a rough indication of how much charge a phone can store, though actual battery life also depends on how it is used.
Silicon-carbon batteries are a newer type of phone battery that can store more energy in a given space than many conventional designs. A phone’s processor, memory, screen and cameras also affect its performance and price, so manufacturers often balance battery life against other features.
Xiaomi competes with other phone makers in markets including Europe, where battery life is one factor people may consider when choosing a handset. Claims about how long a battery lasts depend on usage, settings and network conditions, while charging-cycle figures describe repeated use and recharging over time.
