SmartWiFi is a great app to save battery power on your BlackBerry. It combines your WiFi data and location (by using cell towers) to determine your WiFi hotspot locations. When you are not in these locations, SmartWiFi will turn your devices WiFi off. This saves a tremendous amount of battery, that would normally be spent searching for a WiFi signal.
If you use your devices WiFi frequently, SmartWiFi is a must, especially if you find your devices battery not making it through the day. It is now on sale for $4.99 (normally $9.99) at the CrackBerry App Store. It is compatible for all devices running OS 4.6 and up.
