Battery drains fast / short backup time

1) Check the battery level on the phone's Bluetooth bar (or Bluetooth settings) when connected, and on the Noise Audio app home screen (level can vary slightly with usage).

2) Reduce listening volume and, on the Pro, switch ANC off when not needed – high volume and continuous ANC noticeably shorten runtime.

3) Ensure the case charges the buds fully (lid closed) between uses.

4) For major inconsistencies in the percentage, Reset the buds (case, lid open, case button 10s → "RESET") and reconnect.

5) If one bud consistently dies far sooner than the other after a full charge + reset, that battery is weak / faulty., Battery %ages can be checed at the home page of NOISE AUDIO APP post pairing.

Note: The low-battery side flashes its orange LED once every 30s and plays "Battery Low" every 3 minutes below 10%; below 3.1 V the bud auto-powers-off.

Earbuds turn OFF by themselves / won't stay on

 1) Confirm whether the buds were connected – 10 minutes with no connection = normal auto-off.

2) Keep them connected to a phone and play audio – they should not auto-off while connected.

3) Reset (case, lid open, case button 10s → "RESET") and re-pair.

Note: By design the buds auto power-OFF after 10 minutes with NO device connected, and also power off below 3.1 V. Pairing mode also times out and shuts down after 10 minutes.
