    Qualcomm debuts new battery charging tech for Snapdragon 820


    Qualcomm has designed a new Quick Charge 3.0 feature for its forthcoming Snapdragon 820 chipset, allowing smartphone batteries to be almost fully replenished in half an hour.

    Quick Charge 3.0 will be part of Qualcomm’s forthcoming Snapdragon 820 and employs what the chipset maker is calling Intelligent Negotiation for Optimum Voltage. In practice, this is an algorithim that allows a device to determine how much power to request while charging.

    It claimed a device can be charged to 80 percent from zero in around 35 minutes. This is compared to the average charge time of an hour and a half.
    As well as Qualcomm’s forthcoming 820 processor, Quick Charge will also be available for the 620, 618, 617 and 430 chipsets. The first devices featuring Quick Charge 3.0 are expected to hit the market next year.

    Alex Katouzian, Senior Vice-President, Product Management, Qualcomm Technologies, said: “We are significantly enhancing the capabilities and benefits offered by Quick Charge 3.0 to bring robust fast charging technology to all.

    “Quick Charge 3.0 addresses a primary consumer challenge with today’s mobile devices in helping users restore battery life quickly and efficiently, and does so through leading technology and a robust ecosystem including leading device and accessory OEMs.”

    The chipset maker also revealed additional features of its forthcoming Snapdragon 820 processor. It will offer downlink speeds of up to 600MBps thanks to Category 12 LTE-A connectivity, and up to 150MBps in the uplink due to Category 13. Qualcomm said it has the first processor to support both categories.

    Up to 4×4 MIMO in one downlink carrier will be supported, as well as LTE-U and LTE and Wi-Fi link aggregation.

    Smartphones with the chip will support HD voice and video calling over LTE and Wi-Fi.

    The first devices featuring the chips will go on sale during the first six months of 2016.
