Design and Build Quality

Lightweight and Slim The OnePlus Open stands out with its deceptive lightness and slim profile for a book-style foldable. Our variant, the Voyager Black with vegan leather, boasts a sleek design, while the Emerald Dusk variant adds a touch of green. Despite the gangly Chuan camera module, the weight distribution impressively prevents any toppling sensation. The aluminum frame and vegan leather back contribute to a premium feel.

Innovative Construction The OnePlus Open employs Cobalt M denim in its frame, ensuring a lightweight build without compromising structural integrity. The Oppo trademark Flexion Hinge, a single-spine structure, facilitates a lighter yet sturdy fold. The hinge’s reliability is certified for 10 lakh folds, showcasing OnePlus’s commitment to durability. The placement of buttons, including the embedded fingerprint scanner and alert slider, enhances the overall user experience.

Impressive Display

Internal and External Displays The OnePlus Open boasts an impressive display setup. Both the 6.31-inch cover display and the 7.82-inch internal display feature 10-bit AMOLED panels with 2K resolution. The use of LPTO 3.0 technology allows for a 120Hz refresh rate on the internal display and 10-120Hz on the external. The peak brightness of 1,400 nits in high brightness mode and a remarkable 2,800 nits for HDR content sets a new standard.

Seamless Interaction The minimal crease and an ultra-thin glass protection on the inner display offer a seamless visual experience. The 20:9 aspect ratio on the outer display provides a familiar feel, while the 1.75:1 aspect ratio on the inner display caters to productivity and reading. The Pro XDR display feature, supporting HDR in apps like OnePlus Photos, adds to the visual prowess.

Audio Excellence Equipped with a triple speaker setup and Dolby Atmos support, the OnePlus Open delivers rich and immersive audio. Comparing it to the iPhone 14 Pro Max, the OnePlus Open’s speaker quality holds its ground. Lossless wireless codecs like LDAC and LHDC further enhance the audio experience.


Oxygen OS 13.2 and Android 13 The OnePlus Open runs on Oxygen OS 13.2 based on Android 13, promising four years of software updates and five years of security updates. The collaboration with Google ensures a polished and glitch-free software experience. The outer display mirrors the OnePlus 11’s interface, while the inner display offers an extended tablet-like experience.

Versatile Multitasking The software seamlessly transitions between outer and inner displays, accommodating popular apps like Instagram, WhatsApp, and more. The taskbar, accessible with a long press, facilitates easy app switching. The two-finger swipe down gesture for split-screen mode and the option for up to nine saved multi-window setups add to the multitasking convenience.


Internal Specifications Under the hood, the OnePlus Open houses the Snapdragon AG Gen 2, 512GB UFS 4.0 storage, and 16GB LPDDR5X RAM. Benchmark scores showcase its superiority over the OnePlus 11 and Samsung Galaxy S23 Ultra in various aspects, including Geekbench scores, CPU and GPU stability, and storage speeds.

Gaming Prowess Gaming on the OnePlus Open, particularly on the wider external display, is a delightful experience. Whether playing Call of Duty, Genshin Impact, or intensive games like Alien Isolation, the phone delivers a smooth performance. The FPS data from a Genshin Impact session highlights its gaming capabilities without significant heating or throttling issues.

Battery Life and Charging Speed The 4850mAh split-cell battery impresses with screen-on times ranging from 6 to 6.5 hours in regular usage. Fast charging support, with a 67W charger in the box, ensures a quick 42-43 minutes for a 1% to 100% charge. While wireless charging is missing, the combination of fast charging and prolonged battery life compensates.

Network Support and Connectivity The OnePlus Open excels in 5G performance, providing rock-solid connectivity. With features like Wi-Fi 7, Bluetooth 5.3, NFC, and an infrared blaster, it covers all essential connectivity aspects.

Camera Capabilities

Innovative Camera Setup The OnePlus Open boasts a five-camera setup, including a primary camera, ultra-wide, 3x Periscope, and a couple of selfie cameras. The hardware specifications promise a versatile photography experience.

Primary Camera Performance The primary camera introduces a new pixel-stacked Sony sensor for foldable phones. While lacking in some detail retrieval, it avoids oversharpening. In HDR scenarios, there are slight inconsistencies, but it generally performs well. The natural bokeh in certain shots negates the need for portrait mode, showcasing the impressive color balance.

Ultra-Wide and Periscope Cameras The ultra-wide camera, unfortunately, falls short in detail and HDR performance compared to the primary. The 3x Periscope camera delivers usable results up to 6x in sensor crop, but beyond that, software enhancements falter. While the telephoto provides good edge cutout and depth mapping, it lags behind competitors like the iPhone 15 Pro Max in portrait shots.

Video Capabilities The OnePlus Open supports 4K 60 FPS videos across multiple cameras, with the primary camera delivering sharp footage. However, some jelly effect is visible, especially when compared to the iPhone 15 Pro Max. Low-light videos exhibit noise, highlighting a notable weakness. The inclusion of 4K 30 FPS Dolby Vision videos adds a layer of versatility.

Selfie Camera Performance The 32MP front camera, despite offering 4K 30 FPS video recording, is recommended for stills over video. Using the cover screen mode with the primary camera for selfies yields superior results.
