Battery voltage monitoring

This app monitors battery voltage and gives alerts to unplug or plug the charger

This application monitors your phone's battery voltage and gives a notification alert when you must unplug the charger or when you must connect the charger. So the application maintains battery health. The application is not made for tablets. However if tablet battery has 4.2V (maximum)(3.7V nominal)(battery is charging from a 5V charger), application can run. Because monitoring service from this application runs continuously, application can consume a significant percentage of battery, depending on battery capacity and performance of the phone. Tests made by me showed 0.02% consumption from battery. This service can be stopped and started from application. Test it and see if you like it. For the proper functioning of the application you must start the application after installation and you can give appropriate settings.

New feature was added: You can disable temporarily the sound alarm with a finger tap on notification or double tap on notification in screen lock.

Monitorisation take in consideration battery voltage instead of battery level reported by android, because sometimes, battery level is reported very wrong. So you need to set maximum voltage level of your battery and other settings. Nominal voltage of usual batteries is 3.7V. Usual a smartphone battery have maximum 4.2V, but sometimes you can have a 4.35V battery. This application monitors two kind of batteries: 4.2V and 4.35V. Default setting is for 4.2V. To modify the settings you need to write 4.2 or 4.35, respectively, false or true. For the health of battery, the monitorisation process alerts you before of full charging and full discharging of battery because overcharging and overdischarging deteriorates the battery. Also charging below the maximum gives health to battery. The monitorisation service starts when you open this application for the first time and also starts at boot. If you want a widget that shows battery voltage, you must go to homescreen and add the BatVolt widget, but the monitorisation service works with or without the widget. The monitorisation service start at boot but if you want for some reason to disable temporary (until reboot or until restart this application) the monitorisation service, you can make it. You must know that the widget you can put optional on the screen is based on the service. So, temporarily disabling the service affects widget functionality. Also you can start again the service. If you like this application, please gives a rate on play store. If, for some reason, a notification appears in notification bar, after a phone reboot, for example, and won't disappear, you need to run the application, eventually stop and restart the service and exit.
