OnePlus has officially launched its latest flagship, the OnePlus 12 globally, marking the beginning of this year’s lineup of premium smartphones. Known for delivering a commendable price-to-performance ratio, OnePlus aims to maintain its reputation with the OnePlus 12. A recent teardown by Zack Nelson, the host of JerryRigEverything YouTube channel offers a closer look at the device’s internals, revealing a massive cooling solution that is said to be the biggest in mainstream smartphones.
The massive vapor chamber sinks heat from not only the SoC but also the dual cell battery
The teardown reveals a distinctive split battery configuration, allowing simultaneous recharging of each half, whether utilizing the 50W wireless charging or a faster 100W wired connection. This design not only enhances charging efficiency but also contributes to better overall battery management.
OnePlus has prioritized durability by incorporating rubber rings, gaskets around the USB-C connector, and numerous ribbon cable connectors to safeguard against water damage. However, the standout feature is the massive two-layer vapor chamber, aptly named Cryo Velocity Vapor Chamber. Positioned in direct contact with the Snapdragon 8 Gen 3 SoC and the display, this cooling solution covers an impressive 9,140 mm² area for efficient heat dissipation through the display.
The dual-layer configuration includes a thin gap with a small amount of fluid that recirculates through capillary action of a mesh within the chamber. The constant contact of vanes and recirculating fluid with the copper surfaces ensures effective temperature control.
OnePlus employs this advanced cooling design not only to manage the temperature of the Snapdragon 8 Gen 3 chip but also to cool the batteries and the wireless charging system.
While vapor chambers for smartphone cooling are not a novel concept, OnePlus takes a step further with its dual-chamber design, significantly increasing the surface area. The expanded surface area proportionately improves heat dissipation. The success of this innovative cooling solution in the OnePlus 12 could potentially improve the sustained performance under heavy workloads.
