Why does the battery drain so quickly?

1. Power consumption varies depending on the scenario, with the highest power consumption happening during voice calls.
2. In actual usage, factors such as high volume, audio streaming codec, and environmental interference can impact battery life. We recommend lowering the volume and using the AAC mode to improve battery life.
- To set the AAC mode:
1) Connect the earbuds to your phone via Bluetooth, go to the Bluetooth settings, select Nothing Ear, enter the detailed Bluetooth device settings and choose HD (AAC) or directly enable AAC for Media audio.
2) After connecting the earbuds to your phone via Bluetooth, go to Developer options (accessible through Settings > Additional settings > Developer options), find Bluetooth Audio Codec and select AAC.
- Please note that the specific settings paths may vary depending on your phone's brand and model, so refer to the actual settings.
3. Please upgrade the Nothing X app to the latest version through the Google Play Store or the iOS App Store. In the app, navigate to Settings and select Firmware Update.
4. If the above suggestions still don't resolve your issue, place both earbuds into the charging case, open the case and long-press the function button on the charging case for 10 seconds to perform a factory reset. Then try again.
