Snapdragon 830 will come with Quick Charge 4.0, Google recommends PD

USB-C is quickly becoming a standard but fast charging technologies are far from being compatible with each other.

Qualcomm is said to introduce Quick Charge 4.0 with next years flagship processor, the Snapdragon 830. It will allegedly offer 28 Watt fast charging but Google recommends Android phone manufacturers to use USB Power Delivery instead.
Alexander Fagot,

We saw a rise of competing fast charging methods in 2016. There was the ever popular Qualcomm Quick Charge 3.0 technology, MediaTek offered Pump Express on some if its higher end chipsets. Then Oppo introduced VOOC, which was also used on the popular OnePlus 3. And finally just a few days ago, Huwei announced SuperCharge, yet another proprietary fast charging technology that premiered on the Mate 9. Except for MediaTeks Pump Express, none of the aforementioned Fast-Charging technologies are compatible with UBS Power Delivery, which can deliver up to 100 Watt on compatible laptops with USB-C ports. 

Proprietary Technologies

This means, that mobile chargers from different manufacturers are not interchangeable and if you grab the wrong one, you can say good bye to fast charging. The smallest denominator will be the standard slow 5V 2A charging we have been used to from USB for years. Quick Charge 3.0 can achieve up to 18 Watts instead of 10 Watts while VOOC will deliver up to 20 Watts. Huawei's new SuperCharge can even go up to 22,5 Watt. Next year, Qualcomm is expected to introduce Quick Charge 4.0 together with their newest high-end processor, the Snapdragon 830.

Quick Charge 4.0

Quick Charge 4.0 is said to transfer up to 28 Watt but will offer intelligent voltage negotiation to minimize excessive heat during charging. Google is not so happy about the recent rise of proprietary charging methods and started recommending manufacturers to use USB-C Power Delivery (PD) instead. So far, Google is asking manufacturers nicely by only recommending to use PD in the Android Compatibility Definition Document (CDD) but they also mentioned, that Google may make this a requirement for USB-C equipped smartphones in the future. Most likely, a simple recommendation will not have the desired effect judging from earlier observations with the recommended use of encryption, ArsTechnica recently pointed out.
