Google considers ban on fast charging methods of Qualcomm and OnePlus via USB-C

Google is considering putting a stop to using its own methods for fast battery charging in smartphones, such as Qualcomm Quick Charge, OnePlus Dash Charge and Huawei Supercharge. Instead, manufacturers should use usb-pd.

Google strongly recommends for devices with Android 7.0 to use usb-pd, the standard for fast charging created by USB Implementers Forum when using a usb-c port. In addition, Google notes that the advice may become an obligation in subsequent versions of Android. The search giant does that in the Compatibility Definition document for Android 7.0.

The Android developer will not prohibit the use of alternative charging methods, but says it is not recommended to use a charging method that increases the voltage above the standard level. Qualcomm Quick Charge, OnePlus Dash Charge and Huawei SuperCharge, among others, do.

The text serves as a warning to manufacturers who have their own way of fast charging. They may not be able to use it in future versions of Android. Qualcomm’s Quick Charge, in particular, is widespread and many manufacturers are using the chip designer’s technology. Samsung also has its own fast charging method.

Manufacturers invest in their own ways of fast charging in order to be able to sell chargers that can only quickly charge their own phones. This increases the temptation to buy chargers from the smartphone manufacturer. Because of all those standards, the fast chargers are not interchangeable, something that the USB-C standard should avoid.

The alternative fast charging techniques are in many cases not or hardly faster than usb-pd. For example, Google’s smartphone charges Pixel XL with 18W, although the standard can handle faster charging. Quick Charge 3.0 goes up to 20W.
