Why can't my earbuds charge fully?

  1. If the earbuds and charger case are completely out of power, continuously charge for 4 hrs and observe again.
  2. Replace the cable and charger and see if this works.
  3. Charge the earbud in a lower temperature enviroment and try again. If the issue cannot be resolved, take your device and proof of purchase to an authorised Nothing Service Centre for assistance.
