OEMs must -work with their chipset providers to facilitate in-field firmware updates on -existing chipsets and compatible firmware on new chipsets.</p> - -<p>Additionally, OEMs must continue to configure and submit the power profile -for their devices. However, when the platform detects that Bluetooth, cellular -(as of Android 7.0), or Wi-Fi radio power data is available from the chipset, it -uses chipset data instead of power profile data.
