Qualcomm’s Snapdragon 845 chip is shaping up to be a very promising SoC. Just this Wednesday, Qualcomm disclosed that it has found a way for the new processor to help in reducing the power consumption of wireless earbuds connected to a Snapdragon 845-powered Android handset. 

In a press release published on its official website, Qualcomm introduced the Snapdragon 835’s successor in full detail. The company said its new SoC was designed thoughtfully with tech savvy consumers in mind. However, it may have forgotten to mention in the press release that the processor is also designed to please audiophiles and users that love to stream and listen to music using wireless earbuds or headphones for long periods.

Apparently, Qualcomm has developed a way for Android devices to connect two speakers simultaneously. The company tweaked Bluetooth 5.0 support on the Snapdragon 845 chip, so that it can accommodate two audio devices at the same time. What’s interesting here is that connecting two speakers to an Android device won’t require an extra accessory in-between.

Qualcomm senior director of product marketing Peter Carson told Phone Scoop that the new feature relies on proprietary technology found on both the software and hardware side. The typical setting for Bluetooth audio streaming on Android devices involves sending a signal to one speaker before it is relayed to another speaker. With Qualcomm’s tweak, an Android device can send individual music streams to two speakers or buds simultaneously.

Qualcomm’s invention eliminates the need for an in-between piece of hardware to rebroadcast the signal between two speakers or buds. In effect, the simultaneous relay of Bluetooth signals reduces power drain for the target wireless speakers or earbuds. To have access to this technology however, Qualcomm says phone companies should use the Snapdragon 845 processor and its proprietary APIs.

“The platform’s proprietary enhancements to Bluetooth 5 allow users to broadcast audio simultaneously to multiple wireless speakers, smartphones or other devices and are designed to reduce battery consumption of wireless earbuds by up to 50 percent compared to the previous generation.”

Another upgrade that Qualcomm highlighted in its press release has to do with the more immersive display technologies the Snapdragon 845 features. “[SD845] introduces an integrated Qualcomm Spectra 280 image signal processor and Qualcomm Adreno 630 visual processing subsystem. These brand-new architectures bring high-performance, true-to-life cinematic video capture, along with superior photography to flagship mobile devices.”
