To clarify the impact of this new functionality on battery life, Apple has outlined that the device can last up to 7 hours on a single charge when streaming Apple Music over LTE (via MacRumors).
Apple has rated all Apple Watch Series 3 models for up to 10 hours of battery life when playing music from the watch’s built-in storage.
Since the new watchOS 4.1 also features a new Radio app with access to Beats 1 and other Apple Music radio stations, Apple notes that the Apple Watch Series 3 battery can last up to 5 hours when streaming live radio over LTE.
“Apple says battery life varies by use, configuration, cellular network, signal strength, streaming quality settings, and many other factors. For outdoor sessions with the Workout app, the Apple Watch Series 3 is rated for up to three hours of battery life with streaming audio, GPS, and LTE. That’s one hour less than an outdoor workout without streaming audio.”
