The 9,210mAh dual-cell battery in the new Redmi Note 17 Pro Max is the biggest that Xiaomi has fit in any phone it’s sold in Europe — and remarkably, in some other markets the phone comes with an even larger 10,000mAh single-cell design.
As you can probably guess, this is a silicon-carbon battery either way, one with a high 16 percent silicon content, meaning it’s more energy-dense than most. It’s allowed Xiaomi to fit this huge battery into a phone that’s basically the same size as an iPhone 17 Pro Max, but 8g lighter and fractionally thinner too.
Xiaomi says the Redmi Note 17 Pro Max should give you “worry-free use” for up to three days, or up to 37 hours of continuous video playback. I haven’t been able to put the phone’s battery to the test just yet, but based on the battery life I’ve seen on other recent Android phones, I believe it.
