Rumor: Qualcomm's Quick Charge 4.0 To Support 28W

Qualcomm is a well known chipset manufacturer and is widely known for their Snapdragon processors. That being said, the company is expected to launch its upcoming premium processor, the Snapdragon 830 in the coming months and it has now been reported that the technology in this chipset will be able to support Quick Charge 4.0. According to an accessory manufacturer which was in contact with technology website Fudzilla, Quick Charge 4.0 will debut with the Snapdragon 830 processor and will support fast charging speeds of up to 28W. This will be Qualcomm's most powerful fast charging solution to date.

According to the source close to Fudzilla, Quick Charge 4.0 will have the potential to support charging of 5V, increasing output to 5.6A, which is equivalent to about 28W worth of power. The source also mentioned that a 9V / 4A option may be supported, which will double the existing power output which is currently supported by Quick Charge 3.0, bringing the output to a whopping 36W. This does not seem plausible for a smartphone but there is already a Quick Charge solution at the moment which supports up to 36W to charge high power batteries as well as laptops.

Quick Charge 3.0 which is a feature in many flagship Android devices of 2016, currently allows smartphones to be charged four times faster than regular charging technology, it also works twice as fast as Quick Charge 1.0 and 38% faster than Quick Charge 2.0. Quick Charge 3.0 makes use of an algorithm called Intelligent Negotiation for Optimum Voltage (INOV), which allows the exact amount of power needed by the device to be identified at all times. With INOV, the transferred energy is optimized to make it more efficient. Additionally, the devices can adjust the ideal voltage level supported by that particular device. Quick Charge 3.0 supports 18W for smartphones and offers a wider range of voltages, with 200 mV increments ranging from 3.6V to 20V. If the rumors turn out to be true, and if Quick Charge 4.0 will be able to support 28W for smartphones, this will surpass OPPO's VOOC which currently supports 20W of power and also Huawei's Super Charge which peaks at 22.5W. Smartphones which will be able to support Quick Charge 4.0, will most likely debut in early 2017.
