Google or in the future version of the disabled Andrews Qualcomm MediaTek and other fast-charge technology

According to the United States well-known science and technology network Android central November 8 reported that Google released the new version of Andrews compatibility definition file for fast charge problem warning handset manufacturers try not to use non-standard USB charging.

"We strongly recommend that Type-C devices do not support fast-charge-specific charging methods, such as modifying the default voltage standard or adjusting the Sink / Source current logic, as this may be necessary to support standard USB Power Delivery Chargers and devices in the form of charging. "Although it is currently 'strongly recommended', in future versions of Android, we may require all Type-C devices to support only standard Type-C chargers." b32529c182k289

Now on the market is filled with a variety of fast charging technology, such as Qualcomm fast charge, MediaTek MediaTek Pump Express fast charge, Oppo VOOC flash charge, plus a Dash fast charge, Huawei SuperCharge super fast charge and so on. Some fast-charge technology requires special data lines rather than the traditional charger for fast charging, and because the internal configuration of different phones, different charging rates, if the user mix of equipment, may cause security risks. lm2936mp-5.0/nopb

It is reported that, as Qualcomm QC 3.1 will charge voltage increased to 9 volts or 12 volts, HTC 10 and LG G5 charging time than the general sense are much faster. However, according to the USB Type-C 3.1 specification, the Vbus line should keep the voltage between 4.45-5.25 volts, so that the voltage required for Qualcomm's QC 3.1 is much higher than that of the USB Type-C line - Cable if the current is too high, the consequences would be disastrous. So Google Nexus phone equipped with USB 3.1 Type-C interface, it is not recommended to use high-pass fast charge to charge. In theory, the standard 3A Type-C charger should be the future of the vast majority of USB-C-type Andrews equipment, a relatively fast charging method of reliable.
