Xiaomi Redmi Note 15 Pro+

The Xiaomi Redmi Note 15 Pro Plus has been officially launched in China on August 21, 2025. While the initial launch is exclusive to the Chinese market, global availability is expected to follow a few months later, with regions like India anticipated to receive the device around October 2025. The global variant is rumoured to feature slight modifications compared to the Chinese version, including changes to the battery capacity and camera sensor. Let’s take a look at the main features, specifications, strength, weakness and pricing of the Xiaomi Redmi Note 15 Pro+ (China Version) in Bangladesh.

Key Features of Xiaomi Redmi Note 15 Pro+ (China Version)

Display and Design

The Xiaomi Redmi Note 15 Pro Plus presents a refined and premium design that breaks away from its predecessors with a modern, flat-edged aesthetic. It features a 6.83-inch micro-curved AMOLED display, delivering a satisfying blend of immersion and practicality. This panel boasts a 1.5K resolution (2,772 by 1,280 pixels), a 120 Hz refresh rate, and peak brightness of up to 3,200 nits.

Its screen is shielded by Xiaomi’s Dragon Crystal Glass, which, combined with a fibreglass-coated rear panel, significantly enhances durability, a clear nod toward ruggedness without sacrificing style. The display comes with minimal bezels and a sleek flat border, giving the phone a clean and contemporary profile.

Despite its generous screen size, the overall frame remains slender, at around 7.9 mm thickness. Weighing approximately 211 grams, the device feels substantial yet still manageable and portable.

Processor and Memory

The Xiaomi Redmi Note 15 Pro Plus is powered by the Qualcomm Snapdragon 7s Gen 4, a modern 4 nm chip. The processor is built with an 8-core configuration that includes a performance-focused Kryo Prime (Cortex-A720) core clocked at 2.7 GHz, supported by 3 additional Kryo Gold (Cortex-A720) cores at 2.4 GHz and four energy-efficient Kryo Silver (Cortex-A520) cores at 1.8 GHz.

The graphics unit sports the Adreno 810 GPU, delivering smooth visuals and gaming performance across demanding tasks.

Memory-wise, the Redmi Note 15 Pro Plus comes with generous RAM options, either 12 GB or 16 GB of LPDDR5, ensuring seamless multitasking and future-proof performance. Storage configurations are equally flexible, ranging from 256 GB and 512 GB up to a massive 1 TB of UFS 2.2 internal storage, accommodating even the heaviest users. However, today many similarly priced rivals are offering UFS 3.1 mechanisms, which is disappointing for the Redmi Note Series fans.

Gaming Performance

Powered by Qualcomm’s latest Snapdragon 7s Gen 4, the Redmi Note 15 Pro Plus delivers a modest yet notable enhancement over its predecessor, offering around a 7 per cent uplift in both CPU and GPU performance, resulting in smoother gameplay and improved overall responsiveness. The chipset also introduces Snapdragon Elite Gaming features such as Game Super Resolution, which intelligently upscales visuals for sharper graphics, and Adaptive Performance Engine 3.0, which optimises thermal and load balancing to help sustain high frame rates during extended sessions.

Benchmarks from AnTuTu 10 confirm that the Redmi Note 15 Pro Plus scores around 849,756 points, with the GPU contributing 236,053 points, a strong indicator of its capable graphical performance in this range.

To enhance thermal management further, Xiaomi has equipped the device with an innovative “ice-sealed” cold-pump cooling system, featuring a substantial 5,200 mm² heat-dissipation area that helps reduce thermal throttling and maintain stable frame rates during demanding gameplay.

Camera and Video Capacities

The Xiaomi Redmi Note 15 Pro Plus delivers a compelling photographic setup.

It comes with a 50 MP OmniVision Light Fusion 800 (OV50E) primary sensor with an f/1.6 aperture that employs intelligent light-fusion technology along with optical image stabilisation (OIS), enabling smooth and vibrant shots even in low-light or dynamic conditions.

Its 50 MP telephoto lens offers approximately 2.5× optical zoom and an f/2.2 aperture. Its 8 MP ultra-wide-angle sensor further broadens the framing options with a 112-degree field of view, perfect for sweeping landscapes and group shots.

On the front, a 32 MP wide-angle camera equips the 15 Pro Plus with crisp, detailed selfies and video calls, complete with HDR and panorama support.

Its rear setup can capture footage in up to 4K at 30 fps, with additional recording options at 1080p up to 120 fps and even high-speed 720p slow-motion capture, enhanced by both OIS and electronic image stabilisation (EIS) for steadier video. Meanwhile, the front camera supports smooth 1080p recording at 30 or 60 fps to ensure clean and reliable video calls and selfies.

Battery and Charging Capacity

The Xiaomi Redmi Note 15 Pro Plus packs an impressively large 7,000 mAh battery, marking a significant leap in endurance for the Redmi Note lineup. Xiaomi claims that this cell is designed to remain robust over time, boasting a long lifecycle of up to 1,600 charge cycles.

When it comes to recharging, the phone supports 90 W wired fast charging, enabling rapid power recovery when you're short on time. In addition, it offers 22.5 W reverse wired charging, allowing the device to act as a power source for accessories like earbuds or other phones.
