Here are all the options I have turned on (highlighted) on JuiceDefender Ultimate (except the "proceed" buttons. They're triggers, not toggles.) If I mention something that isn't highlighted, I'll be clear about it. I love it. It works great for me. I took it off the charger at 6 this morning, and at 5:30 this afternoon, the battery was still over 80%. For my phone, that's pretty good. The only thing that doesn't work exactly right for me is the WiFi Location option. It doesn't always turn on WiFi when I get home, but always shuts it off for me when I hit the road. Maybe I'm not waiting long enough, though, so I guess I could just start waiting a little longer and see what happens. Anyway, tab by tab, this is what I've done... About I don't have anything highlighted here. There is an option to enable connectivity only after you unlock the phone, so you can simply check the time without turning everything on, but I carry my work phone with me for that. The droid sits in a bag in my rig. If I'm pulling it out, it's to check for messages and whatnot. It suggests that certain lockscreen replacement apps might work better with it off anyway. Status JuiceDefender Ultimate - enabled Profile - advanced Notification - text Options - quick enable, quick disable (so I can turn it off and on from the notification pull-down screen. Probably don't need to, but I like having the option.) Help - show Controls Mobile data - enabled WiFi - enabled Options - wifi preferred (I didn't highlight the auto disable because if I'm looking for wifi, I'm going to watching for it anyway, and controlling it with my Power Widget. I figure, the less control the app has, the less can go wrong.) 3G - disabled is red. (It actually is a separate app or something, which I used on 2.1, but CM7 doesn't seem to like it. Doesn't matter, things still run fine without it.) AutoSync - enabled (I'm not a big Pandora user, I'm usually on Sirius, and I don't watch videos. I'm not worried about the data usage.) Timeout - disabled is red. Schedules Schedule - enabled Frequency - 30m (I set it to 5m the other day, with duration set to 15s, to see what it did to battery savings. It barely saved any juice at all. If I need things to sync that often, I'm around a power source anyway.) Duration - 30s (It defaults to 1 minute, but once something is syncing, JuiceDefender doesn't kick back in until it's done, so it seemed like a waste to me. I did notice sometimes it didn't give my gReader enough time to sync, but I also noticed it was only several things happened at once. I just turned down the update frequency on my weather widget, and that was enough to do the trick.) Controls - custom, data wifi autosync Night - disabled Peak - disabled Weekend - disabled Triggers Battery - enabled Battery threshold - 15% Charger - usb ac Screen - enabled Options - ignore on low battery Controls - custom, data wifi Traffic - enabled Traffic threshold - high 30s Apps - disabled Location - enabled (I really want this to work right, it might yet. JuiceDefender has to learn here, so I might just be impatient. It is only at 50% so far, after all.) my home network - in use (but I'm home right now, so...) And that's it. That's every option I have turned on or highlighted. Like I said, the "proceed" buttons are always red, but they're triggers. KOLIO mentioned 1X/3G data problems, which I had at first. I also had WiFi issues. Took a bit of tinkering and lots of re-reading to sort it all out. I'm not sure what options might be left out on the free version, but I jumped right to ultimate from the get go to get every option I might want, and have been using it since my 1st day with the Ascend (if I remember right.) Hope it helps someone, but I can't guarantee anything. update: After a couple more days of letting it learn my WiFi spot (home), it now turns my WiFi on and my 3g off as I'm pulling up to the house, and switching them again as I'm pulling away. So by the time I've walked into the house and settled in, anything that I have triggered to sync or download only when WiFi is connected is done without hitting a single button. Unnecessary? Sure, but it's pretty neat.
