While JuiceDefender's basic battery-saving version generally saves enough battery power for all users, JuiceDefender Ultimate provides some key features that people with rooted phones are likely to want. Ultimate installs as an add-on to the regular JuiceDefender app. You get all the regular battery-saving features, such as preset profiles, home screen widgets, mobile data automatic toggling, connectivity scheduling, and location-aware Wi-Fi control. Rooted phones get automatic 2G/3G data toggling and CPU power scaling when idle.
Upgrading to Ultimate gets you automated Wi-Fi control, an additional preset profile, smart brightness control, timeout controls, and the option to configure power use on a per-app basis. You don't strictly have to upgrade to Ultimate, since the basic version does quite well. However, the per-app power controls are exceptionally useful with apps like Twitter, Facebook, and Google+ that can constantly "phone home" in the background. On my 18-month-old Motorola Droid battery, JuiceDefender has given me 14 hours and 54 minutes of battery life, with 90 percent of the battery remaining.
Price: Basic JuiceDefender is free to download; upgrading to JuiceDefender Ultimate will cost $6.96
