OnePlus 15 review
OnePlus 15: Exceptional battery life combined with the Snapdragon 8 Elite Gen 5
OnePlus has created a true flagship, boasting cutting-edge internal components, a refined chassis, and a feature-rich software interface. Its pricing has evolved, it’s no longer the affordable and disruptive smartphone of yesteryear, but its price remains very competitive. The launch price is €950, and the high-end configuration is available for €999 for early adopters; both options are still well below the four-figure entry price charged by most premium competitors.
What sets it apart is the combination of the Qualcomm Snapdragon 8 Elite Gen 5 processor, a 6.78-inch LTPO AMOLED display capable of reaching 165 Hz, and a 7,300 mAh silicon-carbon battery with fast charging. OnePlus has also refined the design, added IP69/IP69K certification, and ended its partnership with Hasselblad in favor of its own DetailMax imaging engine.
The main question is whether the high-capacity battery and top-of-the-line performance justify the price when the camera system is decent but not exceptional and the software support lags behind Samsung and Google.
Quick verdict
The OnePlus 15 is an excellent high-end smartphone for everyday use, ideal for those who prioritize battery life, smooth performance, and good value. Its 7,300 mAh battery offers exceptional battery life, its Snapdragon 8 Elite Gen 5 processor handles all tasks with ease, and its 165 Hz display ensures excellent responsiveness. Charging is fast, its design is robust and water-resistant, and its price is more competitive than many rivals.
Strengths: Exceptional battery life and charging, top-of-the-line performance, smooth screen. Weaknesses: Decent but unremarkable cameras (especially compared to dedicated photography smartphones), only four years of major operating system updates, and a 1.5K resolution that some may prefer for multimedia playback. Ideal for power users, gamers, and anyone looking for a high-performance phone. Excellent value for money in the 900–€1,000 price range.

Quality of design and construction
The OnePlus 15 measures 161.4 × 76.7 × 8.1 mm and weighs between 211 and 215 g depending on the finish. It features an aluminum frame with a glass or fiberglass back, and a front protected by Gorilla Glass Victus 2. The Sand Storm color benefits from a micro-arc oxidation treatment for a more luxurious metallic feel.
It offers a comfortable grip and good balance. Its flat screen and relatively slim profile (for a 7,300 mAh battery) allow for comfortable one-handed use for most users, although its form factor favors two-handed use for extended scrolling. The camera module is a redesigned, perfectly integrated triple-lens square camera. The buttons are well-positioned; the traditional alert slider has been replaced by a programmable Plus button.
The IP68/IP69/IP69K protection rating guarantees excellent resistance to dust, immersion, and high-pressure water jets for everyday use. Its understated and elegant design, far from being ostentatious, makes it practical for daily use without giving an impression of fragility or poor quality.
OnePlus 15 Display
The 6.78-inch LTPO AMOLED display offers a resolution of 1272 × 2772 pixels (approximately 1.5K / 450 ppi) with an adaptive refresh rate of 1 to 120 Hz and a dedicated 165 Hz gaming mode. Maximum brightness reaches approximately 1800 nits in high-brightness mode, and the display is compatible with HDR10+, Dolby Vision, and supports 10-bit color.
In practice, this translates to smooth scrolling, optimal touch responsiveness (thanks to high sampling rates), and good outdoor visibility. Colors are vibrant, and the contrast is typical of high-end OLED displays. The lower-than-QHD resolution is a deliberate compromise that prioritizes energy efficiency and maintaining high refresh rates; most users won’t notice any lack of sharpness in everyday use, on social media, or when watching videos, although multimedia enthusiasts or those who view the screen very closely might prefer a higher pixel density.
Gamers and those who appreciate smooth visuals will enjoy the 165Hz refresh rate. Outdoor users and avid readers will benefit from the screen’s brightness and adaptability. It’s a high-performing and practical display, rather than a champion of pure resolution.
OnePlus 15 Performance
Equipped with the Snapdragon 8 Elite Gen 5 processor with Adreno 840 GPU and up to 16GB of LPDDR5X RAM, as well as UFS 4.1 storage, the OnePlus 15 offers exceptional responsiveness. Everyday tasks, multitasking, and app launches are instantaneous. Its performance is further enhanced by a high-performance cooling system (Glacier or equivalent, depending on available information).
Performance test results place it among the fastest Android smartphones of its generation. The tangible difference compared to previous high-end models is most noticeable during intensive multitasking, high-frame-rate gaming, and ensuring compatibility with demanding applications in the future. RAM management is efficient; the base 12GB configuration is sufficient for most users, while 16GB offers additional headroom.
Thermal behavior is generally well controlled under load, although prolonged gaming sessions at full power can generate noticeable heat, as is the case for most high-end models.
Gaming performance
This is a high-end device designed for gaming. The combination of the Snapdragon 8 Elite Gen 5 processor, a 165Hz display, and a high touch sampling rate ensures optimal fluidity, even at high settings, for titles that support high frame rates. Casual games and those requiring medium to high intensity run smoothly; the most demanding titles can achieve high frame rates with sustained performance.
Battery life remains manageable during gameplay thanks to the large battery capacity, and the screen’s high refresh rate enhances the experience. Heat dissipation is well-handled for extended sessions, although a case or cooling system can be beneficial for very long sessions. It clearly positions itself among high-end gaming smartphones rather than simply as a gaming phone (lacking unnecessary extreme cooling features).
OnePlus 15 Camera system
Main camera: 50MP Sony IMX906 sensor (1/1.56-inch, f/1.8, optical image stabilization). Daytime photos are detailed and offer natural, vibrant colors thanks to the DetailMax processor. Dynamic range and HDR performance are good. Low-light performance is satisfactory for the sensor size, but doesn’t compete with that of high-end models equipped with larger sensors.
Ultra wide-angle: 50 MP, f/2.0, 116° field of view. Usable with a decent level of detail and acceptable distortion; low-light performance is acceptable, but inferior to that of the main sensor.
Telephoto lens: 50 MP periscope with 3.5x optical zoom and optical stabilization. Optical quality is good at 3.5x and remains usable at higher digital magnifications thanks to image processing. Portraits and long-distance shots benefit from the optical range.
Front camera: 32 MP with autofocus. Selfies show natural skin tones and good detail; low-light performance and dynamic range are satisfactory.
Video: up to 8K/30 fps, 4K/120 fps (with Dolby Vision support in certain modes), excellent stabilization, and good sound quality. The front camera is 4K compatible. Overall, video quality is a strong point.
This system performs well for most users and delivers satisfactory results, but it’s not the best in its class. The megapixel count is a marketing ploy; actual quality depends more on image processing than sensor size. Expect good everyday and travel photos, rather than consistently professional quality in all situations. The end of the partnership with Hasselblad means that colors are now optimized by OnePlus’s own processing engine; results vary among reviewers, but are generally natural and detailed.
Battery life and charging
The 7,300 mAh dual-cell silicon-carbon battery is its major strength. Independent tests and user feedback confirm its excellent battery life: often two days of moderate to heavy use, or a full day of heavy use with a significant charge remaining. Video streaming, social media, and mixed use benefit greatly from this. Video games consume more power, as expected, but battery life remains superior to that of high-end models equipped with smaller batteries.
Wired charging reaches 120W (80W with the included charger in some markets, such as the US), with a 50% charge in about 15 minutes and a full charge in about 40 minutes under optimal conditions. Wireless charging (50W) and reverse charging are also available. Heavy users who previously had to recharge their device mid-day will immediately notice the difference. Standby time is excellent.
Software and user experience
The phone comes with Android 16 and OxygenOS 16. The interface is relatively clean, customizable, and fluid, with useful features such as a programmable Plus button, AI tools (Gemini integration, mostly optional AI features), and efficient multitasking. Pre-installed apps are included but remain unobtrusive, unlike some Android skins.
Software support includes four years of major operating system updates and six years of security patches. This is better than what many Android brands have offered in the past, but less than the seven-year commitments from Samsung and Google. For users who keep their phone for three to four years, this is perfectly adequate; those planning to keep it longer should take note. Privacy and security features are standard modern Android fare, with some additions specific to OnePlus.
Audio and connectivity
The stereo speakers offer sufficient volume and clarity for multimedia content and calls; they aren’t professional-grade, but are perfectly adequate. There’s no 3.5 mm headphone jack: USB-C or wireless connection only. Bluetooth 6.0, Wi-Fi 7, full 5G compatibility (bands vary by region), NFC, USB 3.2 Gen 1, and dual SIM/eSIM options fully meet current needs. Practical advantages include fast file transfers, reliable wireless audio, and future-proof wireless network compatibility.
Storage and memory
The basic 12GB + 256GB configuration is suitable for most users. Opting for 16GB + 512GB is a better long-term investment for those who multitask extensively, photographers, or those who store numerous applications and multimedia files. The lack of storage expansion options underscores the importance of choosing the right capacity at the time of purchase. The UFS 4.1 file system ensures fast sequential performance.
AI and smart features
OxygenOS integrates various AI tools (smart search, recorder, portrait enhancement, Gemini integration, etc.). Many of these are useful for summarizing, organizing, or assisting with photo capture and work offline or with embedded processing when possible. Reliability is generally good for the core functions; their availability may vary by region and language. Most do not require a paid subscription. Consider them as valuable extra features rather than essential selling points.
Price and value
At 899–$999 (US) or its equivalent price in your region, the OnePlus 15 sits below many high-end competitors while still offering top-notch performance and exceptional battery life. Photo quality is good, though not premium; battery life and charging are excellent. The main long-term drawback is software support. Overall, its value for money is excellent, especially for users who prioritize endurance and speed over absolute photo performance or the frequency of updates.
