The phone also includes 16GB of fast LPDDR5X RAM, up to 1TB of UFS 4.0 storage, and a large 6,100mAh battery. In this article, we'll cover everything we know about the Xiaomi 15S Pro, including its specs and expected price in Nepal.

Xiaomi 15S Pro Overview

In-house chipset

Let's start with the talk of the town. Xiaomi 15S Pro features an XRING O1 chipset that uses TSMC’s advanced second-gen N3E 3nm process. Inside, you’ll find a 10-core CPU setup with 2 Cortex-X925 prime cores running at 3.9GHz, 6 Cortex-A725 performance cores working between 1.9GHz and 3.4GHz, and 2 Cortex-A520 efficiency cores at 1.8GHz. With a whopping 19 billion transistors, this chip is packed with potential. Backing the CPU, there’s a strong 16-core ARM Immortalis-G925 GPU and a 6-core NPU that handles up to 44 TOPS. Xiaomi proudly claims that this chip crossed 3 million points on AnTuTu, and in Geekbench, it scored over 3,000 in single-core and 9,000 in multi-core tests. That’s impressive for a first-gen in-house chip. What’s even better is the improved efficiency, thanks to a smart cooling system that boosts heat dissipation by 30%, four energy-saving modes, and a dedicated micro-control unit.

Display and Battery

Now, let’s talk about the display and battery. The Xiaomi 15S Pro is sleek and sturdy at 161.3 x 75.3 x 8.33 mm and weighs 216 grams. Up front, it features a stunning 6.73-inch 2K OLED LTPO display with a resolution of 3,100 x 1,440 pixels. The screen refreshes up to 120Hz and hits up to 3,200 nits of peak brightness. It also includes 1920Hz PWM dimming, HDR10+, and Dolby Vision. And yes, it’s protected by Xiaomi’s latest Ceramic Glass 2.0. This combination makes it one of the brightest and clearest displays available. Security-wise, there’s an in-display fingerprint sensor, and with an IP68 rating it’s resistant to dust and water. Under the hood, it packs a big 6,100mAh battery, which supports both wired and wireless fast charging. Xiaomi pairs this with 16GB of fast LPDDR5X RAM and up to 1TB of UFS 4.0 storage. On the software side, the phone runs on HyperOS 2.0 based on Android 15, giving an optimized experience out of the box.
