Despite our efforts to keep the OnePlus Open 2 specifications complete and correct, mistakes get through. If you see anything wrong or missing on this page, please— every report is read, and corrections are made to the record itself.

OnePlus Open 2: common questions

Does the OnePlus Open 2 support wireless charging?

Yes! The Open 2 adds 50W AIRVOOC wireless charging, which was missing from the original model.

How noticeable is the crease on the Open 2?

Thanks to the carbon-fiber teardrop micro-hinge, the crease is practically invisible when looking straight-on and barely felt when running fingers across it.

Snapdragon 8 Elite Gen 5

Silicon Score:9.8 / 10

Score Synchronization: The performance rating (9.8) and graphics capability scored on OnePlus Open 2 are directly calibrated against the empirical benchmark standards of this Snapdragon 8 Elite Gen 5 platform.

What It Is & Microarchitecture

Engineered with second-generation custom Qualcomm Oryon Phoenix CPU cores clocked up to 4.50 GHz, a sliced-architecture Adreno 840 GPU with dedicated GMEM cache, and an 80+ TOPS Hexagon NPU. Built on TSMC second-generation 3nm FinFET (N3P) lithography.

Fabrication Node & Materials

Manufactured on Taiwan Semiconductor Manufacturing Company's enhanced N3P fabrication line using High-NA Extreme Ultraviolet (EUV) photolithography operating at a 13.5nm wavelength. This yields over 220 million transistors per square millimeter with unprecedented gate-oxide consistency.
