This is very useful and light-weight app which protects your phone's battery. It will give you timely alert when the battery is low or when it is overcharged. It can automatically shut off costly network connections when the phone is idle and not in use. The app has 3 different language settings - English (default), Bengali and Hindi. Choose a language which you like, and the alert will auto-adjust itself to your favorite language! While this app tries to increase the lifespan of your phone's battery, the app itself does not affect the battery. This is the area where I found most of the battery management apps in the market totally fail. Unlike others, this app DOES NOT keep running in the background. It simply kills itself when a task is done. Next when it is needed, your android system will wake up this app for few seconds. Again the app will kill itself and make everything clean. So your battery will remain secure and there is no drainage at all. Hope you like this app and it helps you manage your phone better.
