In today’s world, choosing the right smartphone is becoming increasingly complex. Some users prioritise an immersive display, while others look for a stylish design or a rugged build that can withstand everyday wear and tear. Many prefer great camera capabilities, long-lasting battery life, and a fast, smooth user experience. But the real question is—can one smartphone satisfy all these expectations?
In this OnePlus 15 review, we explore a flagship device that comes closer than ever to ticking every box for Indian users.
After using the OnePlus 15 extensively for several weeks, I can confidently say that this smartphone is refreshing, practical, powerful, and beautifully refined. It feels like a device crafted with genuine user needs in mind rather than just spec-sheet bragging rights. If you are planning to buy a new premium Android phone, this OnePlus 15 review will help you understand why the device deserves serious attention.

First Impressions – A Stunning Blend of Style and Strength
The OnePlus 15 arrives in the signature red box, but it’s the new Sand Storm colour that instantly grabs attention. The moment you hold it, you realise the design language has evolved significantly. Imagine holding a smooth marble dice—cool to the touch, premium in feel, and uniquely stylish. That is exactly what the OnePlus 15 feels like, making it stand apart from previous generations.
OnePlus has clearly focused on symmetry and material refinement this time. The bezels are ultra-slim at just 1.15 mm on all sides, one of the thinnest in the industry. This engineering marvel is achieved through LIPO (Low Injection Pressure Over-Moulding) technology, which strengthens the frame while allowing the display borders to remain incredibly sleek.
The phone is available in Sand Storm, Infinite Black, and Ultra Violet, each with distinct textures and finishes. But what impressed me the most is the durability. With IP66, IP68, IP69, and IP69K ratings, the OnePlus 15 is one of the toughest smartphones you can buy today. Whether it’s rain, dust, wet rides, or accidental spills, this device lets you live worry-free.
Performance – A New Standard of Speed and Stability
No OnePlus 15 review is complete without addressing its performance—and this is where the phone truly shines.
At its core is what OnePlus calls the Power Trinity:
- Snapdragon 8 Elite Gen 5 chipset
- Dedicated Touch Response chip
- Dedicated Wi-Fi chip
All three work seamlessly together to deliver consistently powerful performance, whether you’re multitasking, gaming, or switching between heavy apps. OnePlus has also implemented a proprietary CPU scheduler that intelligently allocates resources during gaming, outperforming Android’s standard scheduling mechanism.
Gaming Performance
Although I am not a hardcore gamer, this smartphone made me enjoy gaming more than usual due to its industry-first display and touch features. The OnePlus 15 comes with a 1.5K 165 Hz LTPO panel, offering buttery-smooth visuals. It automatically adjusts between 1 Hz and 120 Hz depending on the content, and in supported games, it unleashes its full 165 Hz potential.
The dedicated touch chip enhances responsiveness with a 3,200 Hz instant touch sampling rate, making actions feel precise and instantaneous.
During my testing, games like Call of Duty, Shadow Fight 3, CarX Street, and F1 Clash ran exceptionally well. The experience remained stable thanks to the built-in dedicated Wi-Fi chip, which improves latency and signal strength, especially indoors.
Thermal Management
Heat management is another strong area. The phone features:
- 360° Cryo-Velocity cooling
- A large vapor chamber
- Graphite layers
- Aerogel cooling beneath the display
Even during long gaming sessions, the OnePlus 15 stayed comparatively cool. I also tested the OnePlus 27W Freezing Point Magnetic Cooler, which amplified the experience during demanding games.
Battery – The Two-Day Power Champion
One of the highlights of this OnePlus 15 review is its exceptional battery performance. The smartphone packs a massive 7,300 mAh dual-cell battery, supported by Silicon Nanostack technology for higher energy density.
Charging is equally impressive:
- 120W SUPERVOOC wired charging
- 50W AIRVOOC wireless charging
In real-world usage, the phone charges fully in about 39 minutes, exactly as the company claims. More importantly, this is the first flagship in recent years that consistently delivered two full days of battery life. For users tired of mid-day charging anxiety, this feature alone could be a deal-maker.
Camera – Versatile, Smart, and Reliable
The OnePlus 15 is equipped with a triple 50MP camera setup:
- 50MP Sony IMX906 main sensor
- 50MP ultra-wide camera (116° FOV)
- 50MP telephoto with 3.5x optical & 7x “optical-quality” zoom
On the front, there is a 32MP RGBW selfie camera with autofocus.
The imaging performance is powered by the DetailMax Engine, a suite of computational photography algorithms that enhance clarity, sharpness, and dynamic range.
Photography Performance
- The phone captures ultra-clear 26MP images, merging multiple frames for optimal output.
- Low-light shots benefit from the Clear Night Engine, which reduces noise and preserves detail.
- The main camera produces crisp, social media-ready photos.
- Zoom images remain usable and sharp within the 7x optical-quality limit.
Video Performance
The OnePlus 15 offers:
- 4K 120 fps Dolby Vision recording
- 4K 60 fps on all rear cameras
- Good stabilisation with accurate colours
This makes it a practical device for vloggers and mobile content creators.
Even though the OnePlus 15 drops its earlier partnership with Hasselblad, the overall camera output remains impressive—reliable enough for everyday photography and solid enough for content creation.
Software – Smooth, Clean, and Smart
The OnePlus 15 runs OxygenOS 16, which continues to deliver a clean, fluid, and bloat-free user experience. Animations are faster, transitions feel natural, and deeper AI integration makes everyday tasks smoother. The interface remains one of the biggest reasons many Indian users love OnePlus phones, and this device only strengthens that reputation.
