The gyroscope ±4000 DPS guarantees extreme precision for demanding gamers, translating even the slightest hand movement into smooth action on-screen.
Cryo-Velocity 360° Cooling System: Controlled Power
To manage the immense power of the Snapdragon 8 Elite Gen 5, OnePlus incorporates its brand new Cryo-Velocity Cooling System 360°, featuring a 3D vapor chamber of 5731 mm² for efficient heat dissipation, an aeronautics-inspired aerogel insulating layer, and a white graphite rear chassis for even thermal distribution.
The result: the smartphone remains cool and comfortable, even after hours of intense gaming or streaming.
A 7300 mAh Battery: A Record For OnePlus
