Truly wireless earbud companies have been fighting for our attention by boasting the longevity of their respective portable charging cases while the earbuds themselves retain a short run time of around 3 hours. While the constraints of the conch of our ears render the housings and the battery quite small, subsequently leading to a rather short life span, Qualcomm (the world leader in 3G and next-generation mobile technologies) has sought another means of extending TWS run time. Qualcomm designed a new generation of Qualcomm TrueWireless Stereo Technology called Qualcomm TrueWireless Stereo Plus to improve the battery life and connectivity of truly wireless earbuds.
Qualcomm TrueWireless Stereo Plus Designed to Improve Battery Life, Connectivity of Truly Wireless Earbuds
The next generation Qualcomm TrueWireless Stereo QCC5100 series breakthrough Bluetooth audio System-on-Chip (SoC) is said to reduce power consumption by 65 percent for voice calls and music streaming compared to the previous generation. Further updates include an easy pairing experience and the ability to autonomously role switch each earbud between primary and secondary roles in order to balance power consumption more evenly between the buds for longer playback time.
This comprehensively integrated single-chip solution is designed to offer manufacturers a highly efficient way of controlling and managing the truly wireless connection to the earbuds and is available in an ultra-small form factor wafer-level 4mm x 4mm CSP package along with a comprehensive suite of software (Audio Development Kit) to support the development of new generation, highly compact, feature-rich wireless earbuds and hearables, according to Qualcomm.
In terms of pairing, when running QCC5100 SoCs, the updated Qualcomm TrueWireless Stereo technology, improved the efficiency and listening experience regardless of the smartphone platform. It also provides an easier pairing experience with no need to pair individual earbuds. Qualcomm TrueWireless Stereo Plus takes it one step further by simultaneously connecting the mobile device to both earbuds. This mode is also engineered to only relay relevant audio content to improve robustness and more evenly balanced power consumption. This mode can reduce up to an additional ten percent of battery life which is said to deliver an extra hour of playtime. This is monumental when it comes to our little wireless music-playing friends.
Designs based on the QCC5100 Series using the enhanced Qualcomm TrueWireless Stereo are expected to be available in the latter half of 2018.
