Auto Battery Saver Lollipop

This application turns on the system's battery saver feature automatically, when the device is disconnected from a power source.

This application uses an accessibility service to turn on the battery saver feature, therefore it must be activated manually from the device settings.
To activate this app as an accessibility service, open the device settings/accessibility then select "Auto Battery Saver", and turn on the service.

Note that this service does not collect any kind of data.
