Enhanced battery life for video conferencing use case in the educational PC segment

ABSTRACT

Remote learning has become increasingly prevalent in the past decade. The current covid climate has provided an exponential boost for concurrent usage with video conferencing, specifically remote learning. For a good learning experience, the system needs to provide consistent performance and responsiveness of all applications in the concurrent use case while also delivering a good battery life to keep students engaged. Additionally, the education PC segment is typically budget conscious and fan-less, with a thermal design power of 6 Watts. Customers prefer to reuse existing chassis, thermal solutions and avoid high-cost bill of material, which comes with power-saving features. In this paper, we present the approach to optimizing video conferencing use case within the constraints of the education PC segment, which comes with the challenge of maintaining perf/watt. We also present pursued optimizations and associated learnings for design, software, and system tuning to enhance performance and battery life and provide a good user experience for video conferencing and concurrent use cases. © 2022 IEEE.
