Qualcomm Quick Charge 4.0

Quick Charge 4.0 Technology by Qualcomm-with USB Power Delivery compatibility

How Does Quick Charging Work ?

Qualcomm uses an algorithm known as Intelligent Negotiation for Optimum Voltage (INOV), to allow everything to fall into place. According to the company, the algorithm is capable of managing how much power the device can request through power cables.

Qualcomm realizes that smartphones and tablets are not the only mobile devices out there, and as such, the company is aiming to get in on the virtual reality craze as well. Not only that, but drones are also in the pipeline, and rightfully so. If we look at the current state of drones, the battery is the main problem so Qualcomm could change that, if even a little bit.

Features of Qualcomm's QC 4.0

• Dual Charge parallel charging technology (now called “Dual Charge++”) to provide up to 20% faster charging and 30% higher efficiency at up to 5 degrees celsius cooler temperatures compared to Quick Charge 3.0
• Quick Charge 4.0 claims to extend smartphone use for flagship smartphones with the Qualcomm Snapdragon 835 chip by 5 hours with only 5 minutes of charging
• With just 15 minutes of charging time, Qualcomm claims it could quick charge a phone up to 50% battery.
• Quick Charge 4.0 also features the third release of Qualcomm’s INOV (Intelligent Negotiation for Optimum Voltage) power management algorithm that includes  real-time thermal management
• Quick Charge 4.0 has been on improving the safety and protection features, with multiple additional layers of protection added to help prevent battery overcharging. 
• 3 layers of over-voltage protection, 3 layers of over-current protection, and 4 layers  of over-temp protection
• Compatibility with USB Power Delivery (USB PD),
•  Qualcomm is also introducing two new power management ICs, the SMB1380 and SMB1381.
• These PMIC are engineered for low impedance, with up to 95% peak efficiency, and support for advanced features like battery differential sensing. The SMB3180/1 will be made available by the end of 2016.

 

Qualcomm’s Quick Charge 4.0 fast charging technology will be available in the next generation of Qualcomm Snapdragon processors, starting with the Qualcomm Snapdragon 835. The Snapdragon 835 is expected to ship in commercial devices beginning in the first half of 2017.
