What happens when your smartphone runs out of battery power? Normally you would have to leave it plugged into its wall charger which usually takes around 7 hours. What if there is a way to cut this time by as much as 75 percent? Getting a smartphone to fully charge will then only take around 2 to 3 hours.
Qualcomm Technologies, Inc., a wholly-owned subsidiary of Qualcomm Technologies, Inc., has developed a technology that does his which is called Quick Charge 2.0 and it’s going to be available for use in Japan this year. The company has partnered with NTT DOCOMO to test out Quick Charge 2.0’s rapid charging capabilities.
According to Alex Katouzian, senior vice president, product management, Qualcomm Technologies, Inc., “Japan has been ahead of the curve when it comes to the adoption of innovative technology. The commitment demonstrated from a leading technology carrier like DOCOMO is an important step towards a strong Quick Charge 2.0 ecosystem in Japan and beyond. We look forward to continuing the integration of Quick Charge 2.0 technology within the mobile industry to further enhance the consumer experience.”
Quick Charge 2.0 is an improvement over the Quick Charge 1.0 technology. The latter can only provide up to 10 watts of power while the former can provide a power of as high as 60 watts which effectively cuts the amount of time needed to charge a mobile device by as much as 75 percent.
Kazuaki Terunuma, Vice President and Managing Director of Communication Device Development Department at NTT DOCOMO, said that “With insatiable consumer usage of their devices, faster charging is more important than ever to bring enhanced convenience to the mobile experience. DOCOMO expects the promise of true fast charging can finally be realized with the introduction of Quick Charge 2.0 into commercial devices and a supporting ecosystem.”
Not all smartphone models will be able to support this new technology as certain requirements must first be met. First, the device itself must be capable of supporting the Quick Charge 2.0 technology which can be through a standalone IC solution or through the PMIC power management integrated circuit of Snapdragon 800, 600, and 400 processors. Next, a compatible wall charger must also be used which contains specific circuitry to take advantage of this fast charging technology.
NTT DOCOMO will be providing its customers with new Quick Charge 2.0 wall chargers later this year which they can use with their compatible devices. Customers will still be able to use their old Quick Charge 1.0 charger on their devices however the time needed to fully charge the device will be longer.
After the introduction of this technology in Japan it is expected to be available to the rest of the world soon.
