Qualcomm Quick Charge 4.0 promises 5 hours of battery life in 5 minutes

On Thursday, Qualcomm not only presented details about its upcoming 10nm Snapdragon 835 flagship processor but also provided some information about its Quick charge 4.0 technology. The Snapdragon 835 SoC is expected in the first half of 2017 and will be one of the first 10nm FinFET chips, not a lot of details were shared but Qualcomm notes Samsung's 10nm FinFET node allows for a 30 percent increase in area efficiency, with a 27 percent improvement in performance or up to 40 percent lower power consumption.

Quick Charge 4.0 is expected to become commercially available in the first half of 2017, this new charging technology aims to make it possible to deliver 5 hours of battery life with just 5 minutes of charging. Qualcomm also mentions 15 minutes of charging should be able to restore a fully drained 2750mAh battery to 50 percent.

There's another advantage too, even though Quick Charge 4.0 is up to 20 percent faster than Quick Charge 3.0, it is also 30 percent more efficient. This results in charging up to 5°C cooler.

Quick Charge 4 features many advancements over prior generations—here are a few:

  • USB Type-C and USB Power Delivery (USB PD) compliant. By incorporating these technologies, Qualcomm Technologies standardizes 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 advanced features designed to extend battery cycle life and provide comprehensive safety. Protection is implemented at multiple levels and throughout the entire charging process to help measure voltage, current, and temperature accurately while protecting the battery, system, cables, and connectors.
  • 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 maximizing 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 advanced 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 divide the charge current, allowing for more efficient thermal dissipation and reducing charge time. Our third generation Dual Charge technology incorporates intelligent thermal balancing engineered for optimized power delivery.
