Having a wristwatch allows you to leave your phone at home and enjoy music, podcasts, or audiobooks while working out. This is just one of the many advantages of owning one. All you need is your smartwatch, some music content (either streamed or locally downloaded if your watch supports mobile data), and a set of Bluetooth earbuds. The battery life of your wristwatch can be severely impacted by playing audio while it’s tracking your workout. Fortunately, Bluetooth LE Audio could improve your watch’s music streaming battery life in the future Wear OS 5 upgrade.
Wear OS 5 with Bluetooth LE audio can improve your watch’s music streaming battery life
As of right now, when you use Bluetooth to wirelessly stream music from your smartwatch to a set of earphones, the audio data is sent through a Bluetooth Classic connection. On the other hand, your smartwatch uses Bluetooth LE, which stands for Low Energy, to transfer data to your smartphone.
Bluetooth LE is a low-energy variant of the Bluetooth radio, as the name suggests. It is specifically made to connect to Internet of Things (IoT) devices that have small batteries, allowing them to run for several days, weeks, or even months on a single charge, depending on how frequently data is transmitted.

Due to the lack of a standardized method, audio data transmission over Bluetooth was not feasible until recently. But as the popularity of Bluetooth hearing aids increased, so did the need to make audio data transmissions via Bluetooth LE possible in order to prolong the battery life of this crucial assistive technology.
As a result, Bluetooth LE Audio—so named because it includes a new set of Bluetooth profiles and functionality for streaming audio over Bluetooth LE—was developed by the industry group that oversees the Bluetooth standard.
