### Battery life

  

Battery life depends on how you're using the device:

*   **Screen on:** 3–6 hours (varies with brightness and audio level)
    
*   **Audio only (screen off):** approximately 24 hours
    

### Charging

  

A full charge from empty to 100% takes about **2.5 hours**.

**Tip:** For the fastest full charge, power the device completely off before plugging it in. Charging while powered off reaches 100% in about 2.5 hours.  
  
**Recalibrate Battery**

*   Charge your device all the way up to 100%.
    
*   Once fully charged, unplug it and use it normally until the battery drains completely and the device turns off on its own.
    
*   Charge it back up to 100% again.
    
*   Repeat the full drain and full charge one more time.
