A number of Android device manufacturers these days, including OnePlus, Huawei and OPPO, seem to be building on Qualcomm’s basic Quick Charge strengths while always looking to take things to the next level with their own personal changes and implementations of fast-charging technology.
But once Snapdragon 835-powered flagship phones come to light sometime “in the first half of 2017”, Quick Charge 4 could be all you need to make sure “you don’t have to spend all day chained to your charging cable.”
Unlike the mostly mysterious SD835 SoC, we know quite a few things about the Qualcomm Quick Charge 4 standard, starting with its main claim to fame – five minutes of charging for extended “premium” smartphone use by five or “more hours.”
Also, “roughly 15 minutes or less” for up to a 50 percent battery charge. Then you have equally impressive generic figures like “up to 20 percent faster charging and up to 30 percent higher efficiency compared with Quick Charge 3.0.” Bottom line, this is blazing fast and ultra-efficient.
Perhaps more importantly though, it’s fully compatible with USB Type-C and USB-PD (Power Delivery) specifications, thus working on the “widest variety of cables and adapters” in the industry.
Last but certainly not least, Qualcomm fine-tuned the heck out of its in-house Quick Charge 4 safety, implementing protection at “multiple levels and throughout the entire charging process to more accurately measure voltage, current, and temperature while protecting the battery, system, cables and connectors.” All to reduce your explosion concerns.

We admit that electricity ain’t sexy talk. But the next generation of top-notch Qualcomm Snapdragon silicon supposedly on the way and that coincides with Android’s big push to standardize charging on the USB Power Delivery spec. Between two giants in the mobile industry, it’s going to be important to see how a battery charges quickly with a method that doesn’t prove too deleterious to cells.
Well, according to sources in the accessories manufacturing business, that way could be called Quick Charge 4.0 and we may see it on the Snapdragon 830 processor next year.
Fudzilla reports that QC4 chargers could run on 5V and adjust between 4.7 and 5.6 amperes for a maximum power potential of 28W. Other configurations could include 9V/4A and so on. Theoretically putting QC4 back on standard voltage metering could make it compliant to Android Nougat and USB 3.0 spec in keeping the Vbus lead in the connector as controller of voltage.
Quick Charge 3.0 was unique in that it adjusted voltage in 200mV increments through a special algorithm called Intelligent Negotiation for Optimum Voltage to determine charging rates at any given time. That’s one of the technical reasons why Google avoided implementing Quick Charge on its Snapdragon 821-equipped Pixel phones.
We should expect to see the launch of Quick Charge 4.0 and the Snapdragon 830 just before its first device is announced early next year. There are plenty of developments to follow and see if this standard is able to fall in line with USB 3.1’s Power Delivery standards.

Google is “strongly recommending” to its manufacturer partners that they follow proper USB specifications for devices running on Android Nougat and even requiring compliance with specific specs.
The latest Android Compatibility Definition Document has expanded upon implementations for a USB port in both peripheral and host modes. There are specific recommendations and requirements now applied in support of the USB Battery Charging specifications, revision 1.2, including USB Power Delivery. Here
- It SHOULD implement support to draw 1.5 A current during HS chirp and traffic as specified in the USB Battery Charging specification, revision 1.2 . Existing and new Android devices are STRONGLY RECOMMENDED to meet these requirements so they will be able to upgrade to the future platform releases.
- Type-C devices MUST detect 1.5A and 3.0A chargers per the Type-C resistor standard and it must detect changes in the advertisement.
- Type-C devices also supporting USB host mode are STRONGLY RECOMMENDED to support Power Delivery for data and power role swapping.
- Type-C devices SHOULD support Power Delivery for high-voltage charging and support for Alternate Modes such as display out.
Google goes on to strongly recommend manufacturers to not support proprietary charging methods that stray from default voltage controls or switch sink/source roles as to render chargers not interoperable between devices. Yep, abandon ye Qualcomm Quick Charge if you want to hop on the Nougat train.
“While this is called out as ‘STRONGLY RECOMMENDED’, in future Android versions we might REQUIRE all type-C devices to support full interoperability with standard type-C chargers,” the listing goes on to read.
Charging over USB-C has been a little bit more of a trick to handle on Android. The Quick Charge 3.0-capable HTC 10 didn’t work friendly with the charger of the Pixel C. Google engineer Benson Leung also has been adamant about having USB-C peripherals following proper charging spec, be it so that a bad cable doesn’t get to fry a phone.
So, Google definitely wants to make sure that OEMs are headed in a safe direction. But will the company continue for a unified, un-fragmented direction, even with hardware spec? We don’t necessarily think so.
