Qualcomm Quick Charge 4 promises 5 hours charge in just 5 minutes
Qualcomm has introduced Qualcomm Quick Charge 4 technology, which will be available with the next generation Qualcomm Snapdragon 835 processor meaning, going forwards, you’ll be able to charge up your smartphone in extremely rapid times.
Besides being faster, it’s designed to be more efficient and run cooler than prior generations. Compared to Quick Charge 3.0, Quick Charge 4 is up to 20 percent faster, or 30 percent more efficient, while charging up to 5° C cooler.
And how will that translate in to real world usage? Well, in an attempt to give you a better sense of this, Qualcomm has adopted a new measurement that helps sum it up simply. They call it 5 for 5, as in 5 minutes of charging can get you 5 hours or more of battery life – which sounds great. Quick Charge 4 is engineered to charge a typical smartphone from zero to 50 percent in about 15 minutes or less.
Quick Charge 4 features other advancements over prior generations, including being USB Type-C and USB Power Delivery (USB PD) compliant. By incorporating these technologies, Qualcomm Technologies standardises the capabilities of Quick Charge 4 adapters, to help ensure that a single accessory supports multiple charging implementations and mobile devices, and that there is consistent performance when faced with the myriad of available charging solutions.
Battery Saver adds features designed to extend battery cycle life and provide better safety. Protection is implemented at multiple levels and throughout the entire charging process and is designed to help measure voltage, current, and temperature accurately while protecting the battery, system, cables, and connectors. Samsung, who are manufacturing the Snapdragon 835 processor, might well be interested in these features..
INOV (Intelligent Negotiation for Optimum Voltage) version 3 is an algorithm engineered so your portable devices can determine what power level to request at any point in time, which allows for optimum power transfer while maximising efficiency. New to Quick Charge 4: a compatible device can request to within 20mV or lower the specific power needed to charge while also running thermal algorithms for case, battery, chip, and connector.
Dual Charge is supported by including a second power management IC in the device (e.g., a smartphone). Charging a device via Dual Charge divides the charge current, allowing for more efficient thermal dissipation and reducing charge time.
At present there are over 100 mobile devices and 300 accessories that come with Quick Charge 2.0 and 3.0. Quick Charge 4 is expected to be commercially available in the first half of 2017.
