How to show battery percentage?

Charger Alert shows your battery percentage in a number of places:

  • In the main screen when you open the app.
  • As an ongoing notification that you can view by swiping down or from the lock screen.
  • In a battery widget if you decide to add one to your home screen.

To always have the battery percentage displayed in the status bar at the top of your android device, follow these three simple steps:

  • Go to your system Settings.
  • Select the Battery section.
  • Find the Battery percentage option and toggle the button on.

This will permanently show the battery percentage remaining in the status bar at the top of your android device.

How to check battery health?

You can check your device's battery health from the main screen of the Charger Alert app.

Under normal conditions your battery's health should be displayed as Good.

If there is a problem with your battery then you may see one of the following instead:

  • Overheated if the battery is too hot and has overheated.
  • Cold if the battery is too cold to operate at optimum capacity.
  • Overvoltage if the battery has too much voltage from charging.
  • Dead if the battery is dead and can no longer hold a charge.
  • Failed if the battery has failed for some other reason.

How to change the alert sounds?

The alert sounds can be changed in the Notification settings.

  • Go to the app Settings.
  • Select Notifications.
  • Choose the alert you want to customize.
  • Select Sound, and pick a sound to use for the alert.

Important Note: due to a current limitation with the Android system, you cannot go back to using the default app sound for an alert once it has been changed, unless you Clear storage of the app data from the system Settings or completely uninstall and reinstall the app again. Unfortunately either method will result in losing your current preference settings for the app.

Why are the battery alerts not working?

If you find that the alert notifications are not working, please check the following:

  • Charger Alert is enabled and running
    Check that the toggle button at the top of the main screen is turned on. You should see an ongoing notification displaying your battery information. This indicates that Charger Alert is enabled and running in the background.
  • Battery alerts are enabled
    Make sure that you have switched on the battery alerts you want enabled from the Alert screen, which is accessed from the icon at the top of the main screen, next to the toggle button.
  • Notifications are enabled
    Make sure that Show notifications is enabled. You can access this from within the app by going to Settings > Notifications or from the system's Settings > Apps & notifications > Charger Alert > Notifications screen.
  • Battery optimization is disabled
    Make sure that any battery saving or battery optimization features are not restricting Charger Alert from running in the background.
    Go to the system's Settings > Apps & notifications > Charger Alert > Battery screen and turn off any such restrictions for the app.

Why is the unplugged alert not working?

By default, the unplugged alert will only trigger when it is activated and the charger is unplugged while the screen is locked.

If you do not have a screen lock set (in system Settings > Security > Screen lock) or simply want the unplugged alert to always trigger any time the charger is unplugged, then you can go to the app Settings and switch off Only if screen locked under the Unplugged settings section.
