Android only: JuiceDefender, a battery-saving Android app we previously checked out, has seen a major overhaul. Much-needed bug and performance fixing was the big change, but the app also saw a major interface overhaul, and a few new features.
At its core, JuiceDefender is an automation tool that turns your Wi-Fi and cellular data on and off to save battery life. Rather than keep a constant connection option, JuiceDefender turns your data connection every so often—15 minutes, 30 minutes, whatever you’d like — and phones home to see if you have new email, voicemail, what have you. Figuring out exactly what you were setting up before in JuiceDefender made your eyes squint and your forehead furrow, and when you did have a good setup going, there were no guarantees it wouldn’t glitch out on you, leaving you without notifications until you discovered it.
