Companion app shows wrong or missing battery level for earbuds

This is usually a Bluetooth connection sync issue or an outdated app rather than an actual battery problem. Reconnecting the earbuds and updating the app fixes most cases.

Symptoms

  • App shows 0% or no battery reading even though earbuds work fine
  • Battery percentage seems stuck and doesn't update
  • One earbud's battery shows but not the other's
  • Battery widget or notification doesn't appear at all

Likely causes

  • CommonBluetooth connection isn't fully synced for battery reporting specificallyAudio can work over a basic Bluetooth profile while the additional data channel for battery reporting fails separately.
  • CommonCompanion app is outdated or has a display bugApp-side bugs can cause battery display issues even when the actual battery data is fine.
  • PossibleEarbuds not seated correctly in the case, disrupting the sync moment when battery info updatesCase-based battery syncing often happens on removal, so a poor seat can skip this.
  • PossibleOperating system permission not granted for battery info displaySome phones require explicit permission for third-party battery widgets to display.
  • Less commonFirmware bug on the earbuds affecting battery reportingA software bug can cause inaccurate reporting independent of the actual battery health.

What to do

  1. Disconnect and reconnect the earbuds via Bluetooth to refresh the full connection including battery data.
  2. Update the companion app to the latest version.
  3. Remove and firmly reseat the earbuds in the case, waiting a few seconds before removing them again.
  4. Check your phone's app permissions to ensure the companion app has any needed battery or notification access enabled.
  5. Restart the companion app completely (force close and reopen).
  6. Check for a firmware update for the earbuds themselves through the app.
  7. Restart your phone if the issue persists across multiple app restarts.

When to call a pro

If battery reporting stays broken after updating everything and reconnecting, this is a software quirk best resolved by contacting the manufacturer's app support team.
