Battery capacities inside smartphones keep increasing, mainly thanks to silicon-carbon batteries. Xiaomi is actually planning to launch a smartphone with a 7,500mAh battery in 2025, it seems.
This information comes from Digital Chat Station, one of the best-known tipsters around. He not only claims that a Redmi phone with such a battery is coming, but that Xiaomi is testing phones with even larger batteries. It seems like it’s only a matter of time before we start seeing phones with 8,000mAh batteries too.
Just to be clear, yes, there are phones with batteries that go well over 10,000mAh and 20,000mAh even. Those phones are usually specialized rugged devices, and they’re very bulky and thick. The devices we’re talking about here have silicon-carbon batteries and are not bulky at all.
The RedMagic 10 Pro, its global variant, that we’ve reviewed recently, has a 7,050mAh battery, for example. The phone is very thin and not heavy at all despite having such a big battery. Yes, this is also a silicon-carbon unit.
Xiaomi already started using silicon-carbon batteries in its mid-range smartphones
Xiaomi has started using silicon-carbon batteries in its budget Redmi phones this year. The Redmi Note 14 Pro 5G and Redmi Note 14 Pro+ 5G, for example, have silicon-carbon batteries. So it’s not hard to imagine the company upping the ante later this year.
Many Android makers are actually using silicon-carbon batteries these days, including HONOR, Vivo, OPPO, and so on. The two most popular ones, however, Apple and Samsung, do not. Samsung is, however, expected to start doing so next year.
Silicon-carbon batteries basically allow OEMs to increase battery capacity without physically increasing the battery size. They’re denser. That allows smartphone makers to keep the phones compact and offer better battery life at the same time.
