    When we unveiled the Qualcomm® Snapdragon™ 810 v2.1 as the processor for the OnePlus 2, we were met with a lot of trepidation - not just from our community - but from the media, as well. It wasn’t simply about our choice in the matter, but more so on whether we could handle the demands of nesting a powerful chip within the innards of our phone while taking care of its delicate thermal envelope.

    Multitudes of reviews later, and what do you know, we silenced most of the critics out there for our choice. After testing multiple flagships using the chipset as well, TechnoBuffalo said “the OnePlus 2 is the coolest running device rocking a Snapdragon 810.” The secret to attaining a perfect balance between performance and reliability in any SoC is by understanding the inherent technical limitations, challenges and opportunities within them. How did we accomplish this? Through a combination of in-depth engineering expertise and some of the most brilliant patent-pending inventions envisioned by our team to make it the thoroughbred processor it was always meant to be. Read on to find out exactly how the OnePlus team did it.


    Enterprising Patents

    We pride ourselves in the development of OxygenOS. The system has been optimized by our small but extremely hard-working team to pair flawlessly with the Snapdragon 810, and we’ve patented the proprietary power and thermal technologies that have been implemented on the OnePlus 2.

    H-Cube
    So, what are these innovations? Our first idea, fondly dubbed “H-Cube” (or Heat Consideration Core Control) focuses on three key principles:
    1. Dynamically activating cores based on the work-load keeping the physical location of cores in consideration. The positional layout of the activated cores help to balance the loads and keep thermal dissipation under optimum levels.
    2. Circulating and rotating the loads between the cores help maximise efficiency based on the Core Heat Circulation idea and finally,
    3. Core Cold Room implementation helps and circulates higher temperatures to disperse from a warmer area of the chip to a cooler one, thereby dissipating heat based on core cluster temperature.
    Thermal-Aware Scheduler
    Another innovation from our team is the Thermal-Aware Scheduler, or TAS for short, which helps to eliminate the inherent flaws of load balancing. The tendency, often found in the majority of SoCs, point to the fact that smaller cores often remain unused under high-load resulting in the bulk being picked up by the bigger core resulting in disproportionate idle times and overheating. What does this lead to? A bad user experience resulting in frequent app slowdowns and a bad user experience in general. The TAS eliminates this bottleneck by balancing the workloads between both the bigger and smaller cores within the SoC regardless of the thermal conditions thereby preventing downtime shenanigans and enhancing battery life.

    Slow Motion Scheduling Group
    We’ve seen a plethora of apps and services, some that are also malicious in nature, that run in the background of your smartphone that keeps the cores active which in-turn slowly depletes your smartphone battery life. The Slow Motion Scheduling Group (SMSG) activated on your OnePlus 2 from the get-go enables “smart scheduling” of apps, activating only those that are being proactively used by the user while hibernating the rest resulting in other activities being put into “slumber”. A win-win situation!


    There you have it - the OnePlus secret recipe for unleashing the powerful processor’s absolute best capabilities on the OnePlus 2. With our patented technology, your videographer needs, TV show binge-watching, and endless sessions of Asphalt 8 will always be cool and smooth.

    Edit: First
    Nice to hear that :) keep doing your job!
    If your phone is heating up and reach a temperature which is dangerous it's turning off automatically. So why this hate?
    Oneplus we love you <3

    But my op2 heats while charging,and gaming too...asphalt 8,God fire rise of Prometheus...
    Is it faulty? -.-

    oneplus engineer's along with Qualcomm engineer's have undercloked the processor to 1.8Ghz, so i wanted to know , the base frequency of sd810 v2.1 is 1.8Ghz or it can again be overclocked to 2.0Ghz(official stock frequency) without any hardware degradation? thanks

    if all this is right then why are you downgrade the clock speed of CPU ?????

    the new nexus 6p which launch recently uses the same processor but with more speed which is 2.0 instead of your 1.8 why is this ???????

    Yay! Love my Two!
    And, yes it gets warm but that's because of the metal... Processor is very cool :cool:

    Gud work OP team, appreciate all the R&D you are putting behind the hardware where other large companies dont really care and keep producing the same phone with shitty and heavy UI over and over again and they dont even justify...

    As an IP lover, I hope that all your pending patents become fully granted patents. But you should add that the chip has Ben downclocked.

    I've read some bad experience with Oxygen 2.1 performance. Is that true?
