One of the biggest problems with current smartphones is battery life. Phone makers are taking different approaches to fight this issue, some are including huge batteries somewhat sacrificing a slimmer design, others are implementing wireless charging capabilities making them easier to keep them charged, then, there have been some technologies that allow these devices to charge faster than before, so even if they need to be recharged during the day, not as much time is spent at each charge. Qualcomm has developed a technology called Quick Charge and its first version allowed devices to be charged 40% faster. Last year, Quick Charge 2.0 was introduced along with many compatible accessories, devices could be charged up to 75% faster. Now, the company is introducing the new Quick Charge 3.0.
This new technology allows devices to be charged four times faster than regular charging technology, it works twice as fast as Quick Charge 1.0 and 38% faster than Quick Charge 2.0. Using an algorithm called Intelligent Negotiation for Optimum Voltage (INOV), the exact amount of power needed by the device is identified at all times, so 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 now offers a wider range of voltages, 200 mV increments ranging from 3.6V to 20V.
Quick Charge 3.0 is backwards-compatible with previous versions, so it can be easily implemented in new devices. It will be compatible with lots of accessories like wall chargers, car chargers, battery packs and power controllers as it supports USB Type-A, micro USB, proprietary connectors or even the new USB Type-C connectors, which are now supported by Android Marshmallow. The new charging technology will be available in processors like the high-end Snapdragon 820, some of the more recent processors from the Snapdragon 600 series including the Snapdragon 617 that was announced a little earlier today, plus the Snapdragon 430 that will power mid-range devices, also introduced today. While some of those processors were announced earlier this year, they still haven't been found powering up any devices, so we will probably see this technology really taking off next year.
