If like me you're always hearing the dreaded beeps of your dying battery at exactly the wrong moment then BattLogger is for you. It keeps complete control of your mobile's battery and will alert you well in advance of any problems. Just check the screen to see how much energy you're losing.
What's more, BattLogger gives you complete control of all settings, so if you need to know when your mobile needs charging, or is fully charged or is below your own set threshold level just set the siren. Then get ready with the plug!
