While fundamental battery technologies and chemistries for consumer electronics continue to move at a glacial pace, innovation in adjacent ecosystems is thriving. Indeed, SA finds that the power consumption beast can be tamed by a range of complementary technologies. A key enabler is wireless charging and the rapid adoption of the Qi standard in smartphones, which continue to represent the bulk of Qi RX enabled devices worldwide. Our latest research finds that 22% of global smartphone shipments in 2019 supported Qi RX, a percentage we forecast will double to 44% by 2024. Across all phones and accessories, over 303M RX devices shipped in 2018, registering positive growth of 11% y/y in 2019 to reach 336M units, amid an overall smartphone market in decline. On the TX side, Qi volumes grew from 81M units in 2018 to 127M in 2019, up an impressive 57% y/y. This detailed report provides independent tracking of wireless charging unit shipments from 2017-2019, by Vertical, by Qi/non-Qi, by RX/TX device Type, by Region, by Half (year).
