A few years ago, Google introduced a useful Fast Pair feature that allows users to check the battery status of their true wireless earbuds quickly. If you’re using Fast Pair-enabled earbuds, you may have noticed that every time you open the case, a notification pops up showing the battery levels of each component: the left bud, right bud, and the case. You also receive a notification when the battery on any of these components is running low, prompting you to recharge them in time.
