The sensor battery level appears inaccurate in the app

Sometimes the app may display a battery level that doesn’t match what you expect.
For example, you may have charged the sensor, but the app still shows a low percentage, or the value updates only after a delay. This behavior is common and usually does not indicate a hardware fault.

1. The battery level may not update immediately

The app may update some values with a delay, including the battery level.
This can happen when:

• the Bluetooth connection is unstable,

• the app is running in the background,

• the phone temporarily limits app communication.

Once the connection stabilizes, the battery percentage usually corrects itself.

2. Bluetooth interference is the most common cause

During connection, there may be:

• brief signal interference,

• temporary loss of communication,

• incomplete data transfer.

In such cases, the app may show an outdated or partial battery value.
 Reconnecting the sensor usually fixes the reading. 

3. App-side issues may also affect battery display

Temporary software issues can cause visual or functional inaccuracies. These can typically be resolved by:

• restarting the Elonga app,

• checking the History section (unsaved records may disrupt functions),

• reinstalling the app with cleared cache + data,

• testing the sensor on another device.

4. Recommended troubleshooting steps

• Disconnect and reconnect the sensor (Bluetooth reinitializes).

• Restart the Elonga app.

• Check Bluetooth stability.

• Review the History section for unsaved or erroneous entries.

• Reinstall the app (clear cache + data).

• Test on another device if needed.

In most cases, the correct battery value appears after these steps.

5. When to contact support

If:

• the battery value is consistently incorrect,

• the sensor drains unusually fast,

• the app does not show battery percentage at all,

We will need:

• your device model,

• operating system version,

• app version,

• a description of charging & connection behavior.

Summary

An inaccurate battery reading is usually caused by:

• delayed data updates,

• Bluetooth interference or dropouts,

• temporary app issues,

• unsaved History data.

The fix is simple: restart, reconnect, check the app, or reinstall.
