I come across a lot of BlackBerry users who carelessly let their battery drain to nothing even when a charger is accessible. If you happen to be one of those, I recommend downloading Plug It In by ShaoSoft.

The great thing about Plug It In, is you can choose the battery level at which you will be notified to charge your BlackBerry. When your battery level drops to that point, a “Battery is low!” message will pop up, your BlackBerry will sound with a notification of your choice, and your LED will light up in a predetermined color as well. All bases are covered in case your BlackBerry is in your pocket or it’s not on your person. After you clear the message from your screen, the LED will turn off as well.Plug It In is available for BlackBerrys on OS 4.6 and above. If your BlackBerry is running OS 4.5 or below, you will need to download Plug It In Lite. Both apps are free and can be downloaded from the links below>>
