Google may disable fast charging technologies such as Qualcomm and MediaTek in future Android versions

According to a report by Android central, a well-known American technology website, on November 8, Google released a new version of the Android compatibility definition file, warning mobile phone manufacturers to avoid using non-standard USB charging as much as possible regarding fast charging issues.

The document reads: "We strongly recommend that Type-C devices do not support fast charging proprietary charging methods, such as modifying the default voltage standard or adjusting the Sink/Source current logic, because doing so may affect chargers and devices that support standard USB Power Delivery charging methods. Although it is only a 'strong recommendation' at present, in future Android versions we may 'require' all Type-C devices to only support standard Type-C chargers."

It is reported that since Qualcomm QC 3.1 increases the charging voltage to 9 volts or 12 volts, the charging time of HTC 10 and LG G5 is much faster than usual. However, according to the specification of the USB Type-C 3.1 interface, the Vbus line should maintain the voltage between 4.45 and 5.25 volts. In this way, the voltage required by Qualcomm QC 3.1 far exceeds the standard of USB Type-C line. If the current passing through the low-specification cable is too high, the consequences will be disastrous. Therefore, it is not recommended to use Qualcomm Quick Charge to charge the USB 3.1 Type-C interface equipped on Google Nexus phones. In theory, the standard 3A Type-C charger should be a relatively reliable method for fast charging of most USB-C Android devices in the future.
