Qualcomm Snapdragon 820 Will Bring Fast Connectivity, Charging
In addition, the X12 LTE modem supports high-definition voice-over-LTE (VoLTE) and video-over-LTE (ViLTE) calling services, which includes support for call continuity between LTE and WiFi. The modem uses Qualcomm's Zeroth technology—an optimized architecture leveraging both hardware and software that is designed to take advantage of the processor's heterogeneous compute capabilities and deep-learning algorithms—to monitor WiFi quality in real time and determine if and when to shift the call between LTE and WiFi. The latest generation of Qualcomm's Quick Charge 3.0 includes a new algorithm the company developed called Intelligent Negotiation for Optimum Voltage, which gives portable devices the ability to determine the optimum power transfer. This not only helps speed up the device charging, but also saves power (it's up to 38 percent more power efficient than Quick Charge 2.0) and keeps the battery from loading too much, which protects the life of the battery, Mark Shedd, director of marketing at Qualcomm, told eWEEK. Quick Charge 3.0 can work with Qualcomm's latest parallel charging configurations to increase charging speed by as much as 27 percent over Quick Charge 2.0 or reduce power dissipation by up to 45 percent. It can charge devices as fast as Quick Charge 1.0. Quick Charge 3.0 offers flexibility in charging voltage, going up in 200mV increments from 3.6V to 20V. This enables the phone to request more precisely the amount of power needed to charge. Quick Charge 2.0 offers four charging voltages—5V, 9V, 12V and 20V.
With Quick Charge 3.0, users can charge a typical phone from zero to 80 percent in about 35 minutes, significantly faster than the almost 90 minutes phones without Quick Charge need, according to company officials.
