Is the OnePlus 15 still a flagship worth buying in April 2026? For longtime fans, the answer is complicated. OnePlus has long been celebrated for delivering smooth performance, long battery life, fast charging, and unique hardware. The OnePlus 13, released in 2025, was a standout device that embodied these values. However, with the OnePlus 15, the company appears to have taken a different path—one that prioritizes trend-following over innovation. This review explores how the OnePlus 15’s design, software, and camera changes might alienate its core audience, and whether it can still compete in the crowded Android market of 2026.
Design: A Departure from OnePlus Identity
The OnePlus 13 was praised for its stylish camera housing and faux leather back, a design that evolved from the OnePlus 12 and 11. But the OnePlus 15 abandons this lineage for a generic square camera bump and muted color options. Without the OnePlus logo, it’s hard to distinguish the phone from any other Android device. The alert slider, a beloved OnePlus staple since the beginning, has been replaced by a ‘Plus Key’—a dedicated button for the Plus Mind AI feature. While change can be positive, these choices feel uninspired and remove the unique character that once defined OnePlus hardware.
Software: OxygenOS 16 Copies iOS Too Closely
OxygenOS 15 was fast, customizable, and included features like Open Canvas for split-screen multitasking. However, OxygenOS 16 on the OnePlus 15 leans heavily into Apple-inspired design. The app drawer now categorizes apps into folders, the interface has a glassy finish, and even the weather and calculator apps mimic iOS. OnePlus even promotes Apple Watch pairing. While OxygenOS 16 remains smooth and optimized, its lack of originality is disappointing. The software that once felt like a breath of fresh air now feels like a reflection of Cupertino.
Cameras: The Hasselblad Partnership Ends
The OnePlus 15 marks the end of the Hasselblad partnership that began with the OnePlus 9. Combined with sensor downgrades across the camera system, this puts the OnePlus 15 in a tough spot. Before Hasselblad, OnePlus cameras were merely adequate. The partnership brought significant improvements in color science and image processing. Without it, the OnePlus 15’s camera performance has regressed. In side-by-side comparisons, the OnePlus 13 still outperforms in detail and dynamic range, making the 15 a less compelling option for photography enthusiasts.
Performance: Still a Powerhouse
Despite these drawbacks, the OnePlus 15 remains a performance beast. Powered by the Snapdragon 8 Gen 5 chipset and up to 16GB of RAM, it handles gaming, multitasking, and demanding apps with ease. Battery life is excellent, with a 5,500mAh cell supporting 100W wired charging—fully recharging in under 30 minutes. Wireless charging is also available at 50W. For users who prioritize raw speed and battery endurance, the OnePlus 15 delivers. But performance alone may not be enough to win over loyal fans.
Price and Competition in 2026
At $899, the OnePlus 15 faces stiff competition from the Samsung Galaxy S26, Google Pixel 11, and Xiaomi 15 Pro. The Galaxy S26 offers a more refined software experience and better cameras, while the Pixel 11 excels in AI features and photo quality. The OnePlus 15’s lower price is its main advantage, but the trade-offs in design and camera may not be worth it for many buyers. For OnePlus fans, the OnePlus 13 remains a better value, especially if found at a discount.
Final Verdict
The OnePlus 15 is a capable phone, but it struggles to maintain the identity that made OnePlus special. The generic design, loss of the alert slider, iOS-influenced software, and camera downgrades are significant missteps. While performance and charging are top-notch, they don’t compensate for the loss of uniqueness. For new buyers, the OnePlus 15 is a decent mid-range flagship. But for longtime fans, it’s a bittersweet farewell to the OnePlus they once loved.
