Redmi Note 15 Announced in China With Snapdragon 6 Gen 3 and a Big 5800mAh Battery

Xiaomi didn’t just stop with the Note 15 Pro models today. It also slipped in a more affordable option, the Redmi Note 15, which could actually be the one a lot of people end up buying. It’s not flashy. At least, not in the same way the Pro+ is. But at first glance, it has that mix of practical hardware and price that tends to define the Redmi brand.

The phone comes with a 6.77-inch FHD+ OLED screen, running at 120Hz. Brightness peaks at 3200 nits, which, on paper, is almost ridiculous for a phone in this price bracket. Will most people notice the difference between 2000 and 3200 nits? Probably not, unless you’re outdoors on a bright day. Still, it’s nice to see.

At 7.35mm thick and only 178g, it’s also lighter than the Pro models. I picked up the Pro+ briefly at the launch, and honestly, the regular Note 15 feels easier to handle. Slimmer, less of a brick in the pocket.

Inside, Xiaomi went with the Snapdragon 6 Gen 3. It’s a fairly new mid-range chip, built on 4nm. In theory, it should balance performance and efficiency well. I haven’t stress-tested it yet, but scrolling through menus and switching between apps during the demo felt smooth.

There’s up to 12GB of RAM and 256GB of storage, though the base model starts at 6GB/128GB. That’s where Xiaomi keeps the price low, and let’s be honest, that’s the version most buyers will probably pick.

The cameras are more modest here. You get a 50MP main sensor (the Light Fusion 400), paired with a basic 2MP depth sensor. On the front, there’s an 8MP selfie shooter. Nothing fancy.

Will it rival the Pro+ with its triple-camera setup? Of course not. But for casual shots — food, pets, everyday photos — it’ll do the job.

The battery is where things get interesting. The 5800mAh capacity is large, especially in a body this slim. Xiaomi says it supports 45W fast charging, plus 18W reverse wired charging. That last bit is unusual at this price point. It basically lets the Note 15 act like a mini power bank in a pinch.

I suspect this could be one of the key selling points — especially for people who don’t want to carry a charger around all day.

Xiaomi gave the Note 15 IP66 dust and splash resistance, which should help it survive rain and the occasional coffee spill. Stereo speakers with Dolby Atmos are also included. Again, impressive for the lower-tier model.

Color options include Midnight Black, Sky Blue, and Star White. The white model, in particular, looks clean and a bit more premium than you’d expect at this level.

Here’s how it’s priced in China:

Sales have already begun, and given the pricing, the base variant will likely be the most popular.

The Redmi Note 15 isn’t trying to win spec wars. It’s the phone you buy because you need something reliable, bright enough outdoors, and with a battery that won’t quit halfway through the day.

Yes, the camera setup looks basic. And no, the Snapdragon 6 Gen 3 isn’t going to impress benchmark chasers. But the price starts at under $150, and that’s where this phone makes the most sense.

It’s very Redmi: practical, a little understated, but exactly what many buyers want. If Xiaomi brings it outside China, I wouldn’t be surprised if it outsells the Pro models by a wide margin.
