Android intends to end the third party fast charging, strong push type-C charging standards – Sohu T tonya mitchell

Android plans to end the third party fast charge, strong push Type-C charging standards – Sohu technology due to the mobile phone battery life is equal to the mobile phone, so vendors in addition to mobile phone battery will be bigger and bigger, also under a lot of effort in charging, fast charging specifications have launched their own. Fast charging standards of many manufacturers, but not necessarily compatible with each other, but also caused a relatively troubled consumers. Fast charging standards for these third parties, the most famous is Qualcomm’s Quick Charge, the standard has been upgraded to version 3. In addition, OPPO VOOC flash charging and MediaTek Pump Express standard is also the right-hand man of many mobile phones. However, Google now seems to be unified charging standards for all Android devices, the end of these fast charging standards of the Warring States era. According to the definition of the latest Android file compatibility updates in October 25th (CDD), a developer found in which the compatibility of 7.7 USB definition section, Google update on the charging standard and specification. They said in the document: "definition, we strongly recommend that Type-C devices do not support those by improving the original Vbus preset voltage changes, or modify the sink source input circuit causes the USB charger device does not support the standard or the current USB power supply equipment Android method." The definition in this section, they also said that although said is "strongly recommended", but they also said that in a future version of Android, they may be mandatory for all Android devices Type-C charger must be compatible with the standard. Android why push Type-C charging standards? In Qualcomm’s Quick Charge 3 as an example, Quick Charge 3 does not require the standard to realize high power charging, because in accordance with the Type-C standard for Type-C, although you can use the maximum voltage and current (20V 5A) to charge, but in the specification must be supplied through special PIN feet, and limit voltage at maximum 5V. However, Quick Charge 3 did not follow this specification to do, directly through the increase of Vbus voltage of 9V to 12V to obtain the purpose of high-power charging. Therefore, Qualcomm’s Quick Charge 3 also does not have the function of data transmission, because they have modified this charging method, but also used the original specification is used to transfer data PIN feet. Through this practice, although in the standard specification of the maximum voltage and current, but not the standard practice相关的主题文章:
