Qualcomm Announced Quick Charge 4.0 with New Snapdragon 835 chipset
Qualcomm Quick Charge 4.0 which was recently announced by Qualcomm when they announced the new Snapdragon 835 chipset and this Qualcomm Quick Charging 4.0 supersedes the Quick Charge 3.0 which was announced in 2016 and this technology will be available in 2017. Compared to Quick Charge 3.0, Quick Charge 4.0 is up-to 20 percent faster, or 30 percent more efficient, while charging up to 5° C cooler. According to Qualcomm one can get 5 hours of battery life and 50% of battery charge in about 5 and 15 minutes respectively of charging.
Qualcomm has added new INOV (Intelligent Negotiation for Optimum Voltage) for extra safety. A compatible device can request to within 20mV or lower the specific power needed to charge while also running advanced thermal algorithms for case, battery, chip, and connector.
Quick Charge 4.0 supports Dual Charge by including a second power management IC in the device (e.g., a smartphone). Charging a device via Dual Charge divide the charge current, allowing for more efficient thermal dissipation and reducing charge time.
Now Quick Charge 4.0 is compliant with USB Type-C and USB Power Delivery (USB PD). It also add battery saver feature which intelligently monitor the battery for getting better life.
Qualcomm says that one should get 20% faster charging & 30% more efficient compared to Qualcomm Quick Charge 3.0. According to Qualcomm as of now only the new snapdragon 835 chipset that comes out in 2017 support Quick Charge 4.0.
