Oneplus has always been aware of the problems of heat dissipation and poor management of core Qualcomm Snapdragon SoC, 810 last, although the choice seems to have been weighted down by his engineers, so that through a post on the official forum, explains which devices used OnePlus in order to create a good balance between performance and hardware optimization between 810 and Snapdragon OnePlus 2 .
According to the company, thel key to achieve a perfect balance between performance and reliability with any SoC is through understanding the technical constraints present, a challenge that can also be seen as an opportunity to better understand where to improve, the engineering team has tried to capture through the use of certain patents.
Nicknamed “H-Cube” (also known as Heat Consideration Core Control) this technology, used by the OnePlus to check the reliability of the Snapdragon SoC 810, focuses on three fundamental principles:
- Dynamic activation of the cores depending on the workload, changing the positional layout of the nuclei in place, helping to balance loads and keep the heat below optimal levels.
- Movement and rotation between nuclei maximising efficiency, in accordance with the principles of Core Heat Circulation.
- Implementation of the system Core Cold Room, which allows to circulate the warmest temperature in cooler areas of the circuit, thus dissipating the heat, according to the temperature of the core clusters.
The second innovation, developed by team OnePlus, is called Thermal-Aware Scheduler, or TAS and in short, it helps eliminate inherent load balancing defects on various core. The tendency, often present in most SoC, underlines the fact that smaller cores operating at frequencies below are often left unused in presence of high load requests, creating consequential downtime and overheating.
This results in some cases, a delays of using apps more frequent and worsening (in time) of the user experience. The TAS will eliminate this bottleneck by balancing workloads between the two core bigger and smaller ones on SoC, thermal conditions, shutting down time and improving battery life.

Unused processes that remain active in the background are often another cause of battery waste, this is because smaller cores that deal with these types of services are not properly optimized. Thanks to Slow Motion Scheduling Group, activates a sort of ” intelligent”programming on processes, activate only those that are actually used by the user, and all other hibernating, further reducing the workload of smaller cores.
This is, according to OnePlus, the secret recipe to bring together Snapdragon 810 with OnePlus 2, offering the best can give this smartphone.
