Battery Charge Notifier for Android

By Utopi Free

Developer's Description

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.

If you are using an Android Pie (Android 9) device, please make sure Battery Optimization is disabled for Battery Charge Notifier. This setting is located at: Apps & notifications Advanced Special app access Battery optimization.

If you are using a Samsung device with Smart Manager, it can interfere with the operation of Battery Charge Notifier by deactivating it when the user hasn't launched the app in a pre-defined period (e.g. 3 days). Since Battery Charge Notifier is designed to work mostly in the background without the need for the user to launch the application in most cases, this can be an issue. You can workaround this problem by adding Battery Charge Notifier to the white list so that Battery Charge Notifier will not get "optimized" by the Smart Manager. Here's how to do so: Settings Smart Manager Battery Detail button in "App power saving" section Battery Charge Notifier Select "Turn Off".

If you are using an Asus device with Auto-start Manager. Please make sure Battery Charge Notifier is allowed to run in background, and that "Clean up in Suspend" is disabled in the Settings menu. Otherwise, Auto-start Manager may decide that Battery Charge Notifier is not being actively used and prevent Battery Charge Notifier to further monitor the battery levels.

If you are using a Huawei device. Please make sure Battery Charge Notifier is set as a Protected App under Phone Manager Power Saving (Android 5)/Battery Manager (Android 6) Protected apps. Otherwise, the system will stop Battery Charge Notifier from monitoring battery level in the background.

If you are using other battery saver type of apps, they may interfere with Battery Charge Notifier. Please try to add Battery Charge Notifier to their white list if applicable when this happens.

There is currently a known issue with Android Lollipop (5.0, 5.0.1) that would affect the accuracy of our app, which may result in delays when getting notifications. Google seems to have fixed this issue in 5.0.2, 5.1 and later.
