The smartphone market continues to heat up as OnePlus officially announced two new devices — the OnePlus 15 and the OnePlus Ace 6, both unveiled on October 27, 2025. While these models share a common DNA of cutting-edge design and fast performance, they cater to different audiences — the OnePlus 15 aiming for flagship dominance and the Ace 6 appealing to the performance-driven mid-range segment. Let’s dive into a detailed comparison between the two to see how they stack up.
The OnePlus 15 and OnePlus Ace 6 both feature a modern and premium aesthetic, wrapped in durable materials.
The OnePlus 15 sports a glass front with Gorilla Glass protection, an aluminum alloy frame, and either a glass or glass-fiber back. It also offers IP68/IP69K certification, making it resistant to both dust and high-pressure water jets. The device feels sleek and solid in hand, measuring 161.4 x 76.7 x 8.1 mm and weighing around 211–215 grams.
Meanwhile, the OnePlus Ace 6 has a slightly larger footprint at 163.4 x 77 x 8.3 mm and weighs 213 grams. It features Crystal Shield Glass protection on both front and back, with an aluminum frame ensuring strength. Like the OnePlus 15, it is also IP68/IP69K certified, giving it equal durability in challenging environments.
Verdict: Both devices are well-built, but the OnePlus 15 edges out slightly with its use of Gorilla Glass and more premium build choices.
The OnePlus 15 features a 6.78-inch LTPO AMOLED display with a resolution of 1272 x 2772 pixels and an impressive 165Hz refresh rate. It supports HDR10+, Dolby Vision, HDR Vivid, and Ultra HDR image support, delivering top-tier visual fidelity for gaming and content consumption.
The OnePlus Ace 6 follows closely with a slightly larger 6.83-inch LTPO AMOLED panel offering 1272 x 2800 pixels resolution and the same 165Hz refresh rate. It too supports HDR10+, Dolby Vision, and HDR Vivid technologies, ensuring vivid contrast and lifelike colors.
Verdict: Both are excellent displays, though the OnePlus 15’s advanced color calibration and Ultra HDR support make it slightly superior for professional-grade visuals.
Under the hood, the OnePlus 15 runs on the Snapdragon 8 Elite Gen 5 (3 nm) chipset with an Adreno 840 GPU. The CPU configuration—2x4.6 GHz Oryon V3 Phoenix L and 6x3.62 GHz Oryon V3 Phoenix M cores—makes it one of the fastest Android phones ever built.
The OnePlus Ace 6, while no slouch, uses the slightly older Snapdragon 8 Elite (3 nm) with Adreno 830 GPU, clocking up to 4.32 GHz on its performance cores. Both devices come with up to 16GB of RAM and 1TB of UFS 4.1 storage, ensuring blazing-fast app performance and seamless multitasking.
Verdict: The OnePlus 15 takes the lead with the newer Snapdragon 8 Elite Gen 5, which provides better graphics, efficiency, and raw speed.
The OnePlus 15 is equipped with a triple camera setup:
It supports 8K video recording, Dolby Vision, and Laser Focus, making it a true flagship-grade imaging device.
On the other hand, the OnePlus Ace 6 houses a dual rear camera setup:
It supports 4K recording at up to 120fps, which is impressive for its price range, though not on par with the OnePlus 15’s versatile lens system.
Verdict: The OnePlus 15 clearly wins in the camera department with a more advanced triple-lens configuration and superior video recording capabilities.
The OnePlus 15 includes a 32 MP front camera capable of 4K recording at 60fps, while the OnePlus Ace 6 offers a 16 MP front shooter limited to 1080p video capture.
Verdict: The OnePlus 15 once again takes the upper hand for content creators and selfie lovers.
Battery life is another area where both devices impress.
The OnePlus 15 features a 7300 mAh Silicon-Carbon battery with 120W fast charging, achieving 50% charge in 15 minutes and full charge in 40 minutes. It also supports 50W wireless charging and reverse charging (both wired and wireless).
The OnePlus Ace 6 packs a larger 7800 mAh battery, also supporting 120W wired charging, reaching 58% in 20 minutes and full charge in 43 minutes. However, it lacks wireless charging but includes bypass charging for extended gaming sessions.
Verdict: The Ace 6 offers longer endurance, while the OnePlus 15 offers more charging flexibility and premium wireless support.
Both smartphones ship with Android 16 and ColorOS 16, offering a seamless and feature-rich experience. Connectivity-wise, both devices support 5G, Wi-Fi 7, Bluetooth (v6.0 on OnePlus 15 and v5.4 on Ace 6), and NFC. The OnePlus 15, however, features a USB 3.2 port, compared to the Ace 6’s USB 2.0, ensuring faster data transfers.
Verdict: The OnePlus 15 edges ahead with a slightly newer Bluetooth version and faster USB connectivity.
The OnePlus 15 sits firmly in the premium flagship category, while the Ace 6 offers exceptional value for its mid-range pricing, making it a great choice for budget-conscious users.
The OnePlus 15 stands tall as a true flagship, featuring top-tier performance, a superior triple camera setup, wireless charging, and cutting-edge display technology. It’s built for enthusiasts who want the best of everything.
The OnePlus Ace 6, however, strikes the perfect balance between power and affordability. It’s ideal for users seeking flagship-like features — such as a 165Hz AMOLED display and 120W charging — without paying flagship prices.
In summary:
Both smartphones prove that OnePlus continues to innovate across every price segment — ensuring there’s something for everyone in 2025.
