Qualcomm Quick Charge 5 can Fully Charge Your Phone in Under 15 Minutes
Qualcomm today announced Quick Charge 5, the latest version of its standard for fast-charging battery-powered devices such as phones. Version 5 is a huge leap over Quick Charge 4, promising four times faster charging. Quick Charge 5 can charge a dead phone to 50% in just five minutes, and 100% in under 15. It does this using a massive 100 watt / 20 volt power supply, and supports even higher wattages and/or voltages. Because individual battery cells and charging circuits inside phones cannot support those power levels directly without overheating, it supports "stacked cell" designs with effectively two batteries (also called 2SnP) — and two or three separate charging circuits — in one phone. Quick Charge 5 can also offer greater efficiency and/or lower temperature while charging. It leverages — and is compatible with — the USB-PD standard. All Quick Charge 5 wired chargers will be able to supply at least 45 watts and 20 volts, while also being full backward-compatible with older versions of Quick Charge. Quick Charge 5 can also be used with wireless charging. Mobile devices with Quick Charge 5 are expected to ship with the next couple of months.
