As demonstrated by the recent launch of the Pixel, Google isn’t afraid of ruffling its manufacturing partners’ feathers, and a new document suggests that the company is ready to flex its muscles again.
The Android 7.0 Nougat Compatibility Definition Document -- essentially an Android 7 rulebook for OEMs -- shows that Google isn’t best pleased about the number of third-party quick-charging battery tech variations being used by USB Type-C devices. These include -- AHEM -- Qualcomm Quick Charge, Huawei SuperCharge, OnePlus Dash Charge, Motorola Turbo Charge and OPPO VOOC.
Google’s Pixel, meanwhile, uses USB Power Delivery technology. As it’s compatible with all chipsets, none of Google’s hardware partners have any reason to avoid it, and it would allow consumers to use the same fast chargers on all USB Type-C smartphones.
Warning: shouty caps below.
“Type-C devices are STRONGLY RECOMMENDED to not support proprietary charging methods that modify Vbus voltage beyond default levels, or alter sink/source roles as such may result in interoperability issues with the chargers or devices that support the standard USB Power Delivery methods,” the document reads.
“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.”
So essentially, it’s Google using a document that’s supposed to be about software to lecture its partners about hardware. That last bit, however, reads like an angry headmaster who's not to be messed with. [Google via 9to5Google]
