Qualcomm has announced its latest generation Quick Charge 5.0 technology, which comes as a successor to Quick Charge 4+, unveiled back in June 2017. However, while its predecessor supported only 45W fast charging, Quick Charge 5 comes with support for 100W fast charging capabilities.
The new announcement from Qualcomm comes after OPPO announced its 125W Flash Charge technology and 65W AirVOOC wireless fast charging. Xiaomi is also working on 120W fast charging technology.
Qualcomm Quick Charge 5 announced
The Qualcomm Quick Charge 5 comes around three years after the Quick Charge 4+ was introduced and is a significant upgrade. According to the company, Quick Charge 5 is up to 70 percent more efficient than Quick Charge 4 and up to four times faster at charging. Moreover, the new charging technology is claimed to be 10-degrees Celsius cooler than the previous generation fast charging tech. Quick Charge 5 can juice up a 4,000mAh battery to 50 percent in five minutes and 100 percent in 15 minutes.
Quick Charge 5 comes with smart identification of adapter capability and is capable of charging at full speed using any USB PD-PPS charger. This is attained by leveraging the existing USB Power Delivery Programmable Power Supply (PD-PPS) standard, which facilitates better control over voltage and current levels during the charging process.
Quick Charge 5 also supports 2S battery systems for two battery cells wired in series, the likes of which we have seen on the recently launched Lenovo Legion Phone Duel. This allows for double the charging voltage and thus faster charging speeds. Additionally, the new technology is backwards compatible with older Quick Charge accessories but will only support the maximum limit of those chargers.
As of now, QC 5 is supported on Snapdragon 865 and Snapdragon 865+ Snapdragon Mobile platforms. However, Qualcomm will also equip Snapdragon 700-series and earlier generations with the latest fast charging tech in the future.
