Qualcomm 100 W charging platform for Android devices
Qualcomm® Quick Charge™ 5 from Qualcomm Technologies claims to be the fastest commercial charging technology for Android devices that is up to 70 percent more efficient than its predecessor.

For optimal Quick Charge 5 performance, Qualcomm Technologies is introducing the newest and next generation premium tier power management ICs (PMIC), Qualcomm® SMB1396 and Qualcomm® SMB1398. Supporting 1SnP and 2SnP batteries, wired and wireless input paths, adaptive operation based on the power source (3 level buck and DIV/2), and scalability (primary and secondary to provide higher power), Qualcomm SMB1396 and Qualcomm SMB1398 are engineered to provide maximum efficiency above 98 percent. Finally, they can support higher than 20 V input voltage operation to accommodate the highest power levels from both wireless and wired power sources.

Quick Charge technology is the industry leading fast-charging method, available on more than 1,200 mobile devices, accessories, and controllers – ranging from car adapters to docking stations – and unifying the handset and laptop charging ecosystem. Backwards compatible with Quick Charge 2.0, 3.0, 4, 4+ and existing handsets powered by the Qualcomm® Snapdragon™ mobile platform, Quick Charge 5 is a single accessory that addresses a variety of charging implementations in mobile devices. Its support for more than 100 W charging capabilities functions within the same footprint as the previous 45 W solution, cuts down on users’ need to purchase additional Quick Charge-certified accessories across devices. Quick Charge 5 is optimized to take advantage of both USB-PD and Type-C technologies, addressing future Android requirements.

The latest generation of Quick Charge 5 not only provides superior charging capabilities but helps intelligently extend a device's battery life and reduce thermal output,” said Zhang Lei, Mi Phone vice president and hardware R&D general manager at Xiaomi.

The Quick Charge 5 charging platform is currently sampling with customers and is expected to appear in commercial devices in Q3 2020. Quick Charge 5 is supported on Snapdragon 865, 865 Plus, and future premium- and high-tier Snapdragon mobile platforms.
