Purchase link
Introduction
The OnePlus 15 is the latest flagship smartphone from OnePlus, officially launched in 2025. It represents a significant step forward in design, performance, and endurance compared to its predecessors. With a massive battery, cutting-edge chipset, high refresh rate display, and a computational photography engine, the OnePlus 15 is built to meet the needs of power users, gamers, and content creators alike.
Design & Build
The OnePlus 15 features a sleek and modern design with flat sides and a squared-off camera island, departing from the circular camera modules seen in some past OnePlus models. 2
It comes in three distinct color options: Infinite Black, Ultra Violet, and Sand Storm. 3
Of particular note is the “Sand Storm” edition, which uses a micro-arc oxidation (MAO) process on its frame to increase durability — the coating is reportedly “3.4× harder than aluminum and 1.3× tougher than titanium.” 4
The rear panel is made from fiberglass in some variants, offering a lightweight but sturdy build. 5
Dimensions are approximately 161.42 × 76.67 × 8.10 mm, with a weight of around **211 g**. 6
Display
The OnePlus 15 is equipped with a **6.78-inch LTPO AMOLED** panel. 7
Key display characteristics:
- Refresh Rate: Up to 165 Hz for super-smooth interactions. 8
- Resolution: 1.5K (rather than a full QHD), which OnePlus says helps support stable 165 Hz performance. 9
- Brightness: The display can go as low as 1 nit for comfortable night viewing. 10
- Color & HDR: It supports 100% DCI-P3 color gamut and reproduces over a billion colors, delivering rich and vibrant visuals. 11
- Bezel Size: Very slim bezels — only about 1.15 mm on each side. 12
- Protection: According to some spec sheets, the screen is protected by Gorilla Glass Victus 2. 13
- Eye Comfort & Features: Includes “Eye Comfort for Gaming,” motion cues, reduce white point, and reminders to rest the eyes. 14
Performance & Hardware
Under the hood, the OnePlus 15 is powered by the **Qualcomm Snapdragon 8 Elite Gen 5**. 15 This is a 3 nm process chip, offering both high performance and energy efficiency. 16
Key hardware and performance features include:

- Gaming Engine: The device includes an “OP Gaming Core” — a gaming-optimized engine that promises always-on 120 FPS in certain games and better CPU/GPU efficiency. 21
- Cooling System: A 360° Cryo-Velocity Cooling System with a 5,731 mm² 3D vapor chamber helps dissipate heat under load. 22
Battery & Charging
One of the most striking features of the OnePlus 15 is its large **7,300 mAh silicon/carbon (NanoStack) battery**, which is the largest ever in a OnePlus flagship. 23

- Wireless Charging: 50W AirVOOC wireless charging. 25
- Bypass Charging: Supported — this allows the phone to charge directly from the charger under high load, reducing heat generation during heavy usage (like gaming). 26
- Longevity: According to OnePlus, the battery is designed to retain over 80% of its capacity after four years of use. 27
- Temperature Resilience: The battery is rated to operate in very cold environments (down to –20 °C) — showing the company’s build confidence. 28
Cameras & Imaging
The OnePlus 15 has a powerful triple-lens rear camera system. 29 Here’s a breakdown:
- Main Camera: 50 MP sensor (Sony IMX906), with f/1.8 aperture and OIS. 30
- Ultra-wide Camera: 50 MP lens (Samsung), f/2.0. 31
- Telephoto Camera: 50 MP telephoto lens, ~3.5× optical zoom with OIS. 32
For the front camera, the OnePlus 15 packs a **32 MP selfie shooter** capable of recording up to 4K at 60 fps. 33
OnePlus has introduced a new computational imaging engine called the **DetailMax Engine**, which is designed to improve clarity, dynamic range, and detail in photos. 34
Other camera features include:
- Ultra-Clear 26 MP Mode: A mode that enhances clarity in certain conditions. 35
- Clear Burst Mode: Captures up to 10 frames per second to get the best shot. 36
- Video Recording: Rear cameras can record up to 8K at 30 fps, and 4K at 120 fps. 37
