Talk Time

• The Jawbone is capable of up to 4.5 hours of talk time. That is time that you are actually using the device to speak to someone. This time is also shared when you are using the device to listen to music or podcasts.
  
  

Standby Time

• The Jawbone is capable of up to 10 days of standby time. This is time that the device is on but not actively being used. Using the device for calls or listening purposes will decrease the standby time. With that being said, actively using the the devices will not garner you 10 days without recharging.
  
  

Considerations

• Talk and standby time vary based on a lot of variables. This is why manufacturers will always use the wording "up to." The time that is advertised is the highest rating that they got with their testing. In everyday normal use, you may get less talk and standby time or even more.
