About notifications
If you place a date widget with battery level display, the battery level acquisition service will run and a notification will be displayed.
If you turn off "Allow notifications" in the app information, notifications will not be displayed.

Battery remaining amount acquisition service
This is a program that obtains the remaining battery power and updates the widget's remaining power display. Run in the background. Do not limit background execution with power saving settings, etc. If this program stops, the widget's battery level display will not be reflected correctly.
