Last week Qualcomm introduced the Snapdragon 835, which will be integrated into many high-end phones next year. Together with the processor, Qualcomm also updated their fast charging technology Quick Charge to version 4.0 as rumors correctly predicted ahead of the presentation. Of course the new version includes improvements in the speed of its fast charging technology by increasing efficiency during a charging process thanks to new versions of some of Qualcomm's technologies like Intelligent Negotiation for Optimum Voltage (INOV) or Dual Charge, making sure that both charger and battery will not overheat or overcharge and even stay cooler during the charging process.

Qualcomm promises 5 hours of usage after only 5 minutes of charging or 15 minutes of charging for a 50 percent load on a theoretical 2,750 mAh battery. While this is less than competing proprietary technologies like Huawei's recently announced Supercharge, Quick Charge 4.0 will have a big plus compared to most other proprietary standard: it will be compatible with the USB-C standard Power Deliver (PD). That means, that in the future, a USB-C-PD compatible laptop charger will be able to fast charge a Quick Charge 4.0 compatible smartphone and vice versa.

However, since Quick Charge 4.0 will be a superset of USB PD, efficiency might be a bit less with a general PD-charger, so Quick Charge 4.0 certification will still be necessary for optimum efficiency and speed. Google recently recommended manufacturers to make USB-C smartphones compatible with USB-C Power Delivery, it seems like Qualcomm was the first one to listen to Google. Quick Charge 4.0 compatible smartphones will be released together with the Snapdragon 835 in the first half of 2017.
