Fast-growing device maker OnePlus said that it will use an “improved version” of Qualcomm’s Snapdragon 810 processor in its anticipated OnePlus 2 device, against a backdrop of uncertainty about the performance of the silicon.

“Although there have been reports that the 810 runs warmer than its predecessors, we assure you that we have taken all the necessary precautions and beyond to prevent this from occurring in the 2. We worked very closely with Qualcomm’s engineers to integrate an improved version of the chipset (v2.1) in the OnePlus 2, and fine-tuned both hardware and software,” the device maker said in a blog post.

The company also said its own fledgling OxygenOS platform has been “optimised to work beautifully with the Snapdragon 810”, including a proprietary technology which handles a variety of tasks for the chipset – including knowing which of the eight cores to use, and avoiding using cores that are next to each other.

In a subsequent post, it said that the Snapdragon 810 it will use “runs the same eight cores for stability, but at 1.8GHz for cooler temperatures” – around 10 per cent slower than in its standard guise. It also said that the part costs “almost 60 per cent” more than the Snapdragon 801 it used previously, “and we’re not getting any discount”.

It also said the device price will “certainly be higher” than a mooted $322 price point.

Concerns about the performance of Snapdragon 810 began early this year, when it was revealed that Samsung had opted not to use the chip in its flagship Galaxy S6 series devices. This led to Qualcomm issuing a statement with comments from supporting partners.

Since then LG has also opted not to use Snapdragon 810 in its new flagship, G4, although it uses it in its high-end G Flex 2 smartphone. And question marks over the performance of the chipset have also been raised when talking about weaker than expected demand for HTC’s One (M9), which is powered by the Qualcomm silicon.
