Beocom Portal support up to 23 hours of talk time with Active Noise Cancellation.
If you are listening to music at a moderate volume level, the battery in your Beocom Portal can support up to 47 hours with Active noise cancellation (connected to the Beocom Link A or C dongle and using ANC.)
In general, the battery life depends on volume, music intensity, and equalizer settings. This means that the battery drains faster at a higher volume when playing higher intensity music like rock or heavy metal or bass heavy music.
