Qualcomm’s latest charging solution offers support for 100W of power and above, as well as backward compatibility with older Quick Charge versions and USB Power Delivery, including the PPS variant. Besides USB Power Delivery, Qualcomm’s Quick Charge is the only other widely supported charging standard, meaning we’ll likely see Quick Charge 5 inside a number of future smartphones from several manufacturers.
In terms of speed, Qualcomm boasts that Quick Charge 5 can power up a 4,500mAh battery to 50% in just 5 minutes and will reach full in less than 15 minutes. That’s a tad faster than Oppo’s 125W solution, but we’re talking by mere minutes here. Qualcomm also touts that version 5 is up to 10°C (50° F) cooler, 70% more efficient, and up to 4x faster than its predecessor.
However, the exact speeds on offer depend on the implementation inside any given device. Quick Charge 5 supports a variety of input voltages and currents. These range from 3.3V to 20V, with 3A, 5A, and greater than 5A of current supported with the right USB cables. This is all cross-compatible with USB Power Delivery, which Qualcomm uses for device-to-device communication and power handshakes.
Speaking of compatibility, Quick Charge 5 accessories play nicely with devices sporting any of the previous versions. So hopefully third-party accessory uptake will be quite quick. Just like Quick Charge 4 and 4 Plus, version 5 also works with the iPhone 7 or newer and other USB Power Delivery smartphones. Likewise, Quick Charge 5 smartphones work with all previous generation Quick Charge accessories, but speeds are limited to their older capabilities. So you won’t need to run out to buy new power accessories unless you want the very fastest speeds.
Although the new standard can push power above 100W, many devices will likely end up in the 45W range. This is because 20V charging requires a new (for Quick Charge) dual stack battery design. This is just one of the new features added to Quick Charge 5. Qualcomm now includes dual charge technology to increase charging current while spreading out heat dissipation to keep within existing thermal profiles.
Many flagship phone owners will be elated to know that Snapdragon 865 and 865+ already support Quick Charge 5 technology. All future premium- and high-tier chipsets from Qualcomm will also arrive with this technology in tow.
Currently, the chipmaker is testing this charging solution and we should expect it to appear in commercial devices in Q3 2020 – i.e. sometime later this year.
