Design and main display
Foldable devices with book-style designs pose challenges in terms of portability and usability. Holding them for extended periods can be fatiguing due to their weight, and concerns about their durability often linger. OnePlus introduces a novel ‘Flexion hinge’ design on the OnePlus Open, aiming to reduce screen weight and creasing. Employing a water drop-shaped hinge, commonly seen in foldables, OnePlus has innovated to improve this design aspect.
The OnePlus Open boasts a 6.3-inch cover display that stands out for its practicality among foldables. Featuring a 10-bit AMOLED screen, it offers 2K resolution (2,484 x 1,116 pixels) and a variable refresh rate ranging from 10Hz to 120Hz. Additionally, it includes a ‘ceramic guard’ screen protector.
The back houses dual 48MP cameras (wide and ultra-wide) alongside a periscope-style telephoto lens (3X optical and 120x digital), all enclosed within a substantial round camera module. The module’s size and thickness might not appeal to all users. Meanwhile, the cover screen sports a central hole-punch camera, while the main display accommodates the selfie camera at the top-right corner.
The OnePlus Open ships with Android 13-based OxygenOS 13.2, Snapdragon 8 Gen 2 SoC, 16GB of LPPRD5 RAM, and 512GB of UFS 4.0 storage.
The OnePlus Open features a 4,805mAh battery with 67W charging, offering a commendable performance by foldable standards. In the PC Mark battery test, it endured for over 13 hours, comparable to the Galaxy Z Fold5.
