The battery life on Powerbeats is one of the best compared to any wireless earbuds. While testing them, I found that they can offer up to 0 hours of audio playback on a single full charge. This is an impressive time when compared to other brands of a similar price range. While using the Powerbeats on Apple products such as the iPhone or Apple watch, I got over 10 hours of playback while consistently listening to 75dB audio. A single full charge of the wireless earphones can also support up to 6 hours of call time. The Powerbeats come with a charging case, giving you a combined playback time of over 24 hours. The case LED on the front will turn red when it is below 40%, and it would be best if you connect to a power source. Once the wireless earphones are completely out of battery, placing them on the charging case will give them up to one and a half hours of playback time for every 5 minutes of charge.
