Xiaomi 15S Pro Could Bring Back a Forgotten Tech—And 90W Charging Is Just the Start
The Xiaomi 15S Pro is shaping up to be one of the most intriguing flagships on the horizon. We’ve already reported on how it’s expected to share certain features with the upcoming Google Pixel 10, but now there’s even more reason to keep an eye on this device.
According to new leaks, the Xiaomi 15S Pro may mark the return of Ultra Wideband (UWB) technology, something Xiaomi hasn’t used since the Mix 4, released nearly five years ago. And if that’s not enough to get you curious, the phone is also tipped to support 90W fast charging, making it one of the speediest devices for topping up on the go.
UWB: The Real Game Changer?
While 90W charging is impressive and certainly convenient for users who are always on the move, the rumored inclusion of UWB support is arguably the more exciting development. If true, it could signal a broader push from Xiaomi to reintroduce the tech across future flagship devices.
So, what is Ultra Wideband, and why should you care?
Ultra Wideband (UWB) is a short-range wireless communication protocol that’s quietly becoming a premium feature in modern smartphones. Apple introduced it starting with the iPhone 11, and it’s now standard in recent Samsung Galaxy S and Z-series devices, as well as Google Pixel phones. Now, Xiaomi might be ready to join the party—again.
What Makes UWB So Special?
Unlike Bluetooth or Wi-Fi, UWB operates across a much broader frequency spectrum at lower energy levels. This allows it to deliver extremely accurate spatial awareness, enabling devices to locate and interact with each other within centimeter-level precision.
Here’s what UWB can unlock:
- Digital car keys: Your phone can unlock your car only when you’re physically close to it.
- Precise file sharing: Like an upgraded AirDrop, UWB helps devices “point and send” with greater accuracy and security.
- Smart home magic: Walk up to your smart speaker or TV and have your phone auto-connect, hand off content, or prompt controls.
- Next-gen tracking: When used with compatible tags, UWB can help find lost items with far more precision than traditional Bluetooth trackers.
But that’s just scratching the surface. As adoption grows, UWB is expected to power future innovations in augmented reality, indoor navigation, and even contactless access control systems.
What It Means for Xiaomi (and You)
Bringing UWB back could position Xiaomi to compete more directly with Apple, Samsung, and Google on ecosystem-driven experiences. And if the Xiaomi 15S Pro really is bringing this tech to market, it could signal a new era for the brand’s premium lineup—one focused not just on raw specs, but on smart, seamless interactions.
Combined with ultra-fast 90W wired charging, rumored flagship-tier internals, and Xiaomi’s continued refinement of its software experience, the 15S Pro could be one of the most feature-complete Android phones of the year.
In a market where specs alone no longer wow, smart features like UWB might be what truly sets a phone apart.
