Using a power-management tool like JuiceDefender is clever, but it's not the only option. DroidWall adds a configurable firewall to help you control which apps are using your data stream. This has become exceptionally important in the age of limited data plans, and can also act as a solid security measure.
Based on the Iptables Linux firewall, DroidWall can allow only whitelisted apps, block blacklisted apps, and allow access based on whether you're using a mobile data network or Wi-Fi. It's a small, free app that brings a smart, PC style of protection to your Android.
