Qualcomm Introduces Quick Charge 3.0
Qualcomm just unveiled their new fast charging technology that should be available next year with their new Snapdragon 820 processor.
Qualcomm today announced a new version of their fast-charging technology called Quick Charge 3.0. As the name suggests, it is the third generation and the first that will employ Intelligent Negotiation for Optimum Voltage (INOV), a new algorithm developed by Qualcomm Technologies, designed to allow portable devices the ability to determine what power level to request at any point in time for optimum power transfer, while maximizing efficiency.
Compared to Quick Charge 2.0, Quick Charge 3.0 is designed to be up to 38 percent faster which means that you can charge a typical phone from zero to 80 percent in about 35 minutes. Quick Charge 3.0 also implements additional steps to help protect battery cycle life.
We all know just how important role battery life plays in modern smartphones. Many modern smartphones get just 4-6 of SOT (Screen On Time) and not every phone has a replaceable battery. That means that charging is something that has to happen much more often compared to the past. Larger 3000+ mAh batteries can take hours to reach full charge without the help of fast charging technology. Reaching 80% in just 35 minutes gives you plenty of juice to get through the second part of the day and something over 30 minutes is short enough time that it can be easily done during lunch break.
If you cannot wait to use Quick Charge 3.0 in action, you will have to grab smartphone with either Snapdragon 820, 620, 618, 617 or 430. These processors should start to appear in various mobile devices next year.
There are also interesting improvements when it comes to the internal technical design of this new charging technology. According to Qualcomm, while Quick Charge 2.0 offers four charging voltages at 5V, 9V, 12V and 20V, Quick Charge 3.0 provides flexibility with 200mV increments from 3.6V to 20V. This allows the phone to request just enough voltage to reach the desired charge current, resulting in minimized losses, increased efficiency, and improved thermal performance.
It is not unsurprising that Quick Charge 3.0 maintains both forward and backward compatibility with the previous version of Quick Charge as well as with connectors, including USB Type-C.
It will be interesting to see if MediaTek answers to Quick Charge 3.0 with further improvements to their own fast charge technology called Pump Express and Pump Express Plus.
The bottom line is that any improvements to the current charging and battery technology are more than welcomed. However, it will probably still be some time before we can use our mobile devices for long periods of time without any worries about battery power.
