Light weight app that notifies user at user defined battery levels to either charge the device, or to unplug and stop charging. This helps in observing the 40-80 rule of Li-ion batteries.

Most battery apps on the market only notify when the battery is fully charged, but only a few that notify user at user defined battery levels, and even fewer, if any, that can do so accurately with very little resource. That's why we wrote this app.

The reason why we want to stop charging before a battery is fully charged is to extend the lifespan of the battery. Virtually all mobile devices nowadays uses Lithium batteries and Lithium batteries work best when they are charged in the middle range, say 40% to 80% or 50% to 75%. So if you are really particular about optimizing and extending your battery's lifespan, Battery Charge Notifier could help you achieve it.

◆◆◆ Known Issues ◆◆◆
◆ Issue: If the selected notification sound is located on an external storage (e.g. on a micro-SD card), no notifications will be triggered. This is due to the fact that our app currently doesn't require the permission to read external storage.
Solution: To workaround this issue, the user can move the sound file from the external storage to the internal storage. We are working on requesting this permission as necessary on a future release. 
◆ On Android 5.1.1 or order, the Battery Optimization warning is shown on the settings page despite the fact that Battery Optimization isn't available until after Android 6.0.
Solution: Nothing needs to be done as the message is harmless. We will remove this message accordingly for Android versions before 6.0.

◆◆◆ Frequently Asked Questions ◆◆◆
◆ Q: Why is there a persistent notification icon starting from version 3.0.12, on Android 8.0 and above?
A: The persistent notification icon is there mainly to serve two purposes. 1) To let the user know that battery levels are being monitored, 2) A Google requirement which requires all background running apps to show a user noticeable notification.
◆ Q: Is there a way to remove the "persistent notification icon"?
A: Yes! Simply go to Settings, Apps & notifications, Battery Charge Notifier, Notifications, and disable the notification channel called "Battery Level Monitor Service".
