The convenience of wireless charging is unparalleled, but the fastest way to power up remains via a cable. Qualcomm today announces a slew of speed and safety enhancements on Quick Charge 5.
Qualcomm claims the Quick Charge 5 is the “first commercially viable” quick charging solution that supports over 100W and is available for use by handset makers today. This emphasizes the broader range of competitive single-OEM offers for other manufacturers.
The main, touted capability is to charge a 0 to 50% 4,500mAh battery in five minutes, with a full top-up in 15 minutes. It’s 70& more power efficient, or four times faster, compared to Quick Charge 4. That’s 10 times more output power compared to its 2013 inaugural fast charging tech.
Support is provided for 2S (stacked) batteries and 20 Volts power supply. With the Qualcomm SMB1396 and SMB1398, the company is launching new power management ICs. There are a range of “extreme safety measures” available for that amount of power running.
A key measure is the latest “Smart Identification of Adapter Capabilities” from Qualcomm. This will monitor and check the real, rather than just trusting, limitations of a connected charger to adjust current, power and voltage behavior. There are also various levels of protection at the handset-level regarding voltage , current, thermal, and timer.
With respect to ecosystem support, Quick Charge 5 is backward compatible with versions 2.0, 3.0, 4, and 4 +, with permutations explained in the chart below. Qualcomm explains how it hacks both USB-PD and Type-C as well. These QC5 charging bricks will work with laptops as well as other form factors as well.
The Snapdragon 865 and 865 Plus, as well as “future premium-and high-tier Snapdragon mobile platforms” support Quick Charge 5. Xiaomi will be one of the first partners to incorporate the technology in the months ahead.
