3G sometimes doesn't turn on when WiFi turns off

[CharlesLewis]

If I am in an area where WiFi is not available or where the WiFi requires a password I don't have, my phone will either turn off WiFi automatically or I turn it off with a toggle app. At that point, 3G should automatically come back on, and it usually does. But sometimes, nothing happens, so I go into settings and discover that the checkmark for "Enable data access over Mobile network" is gone. If I re-check the box, all works as it should.

Any suggestions about what might be causing the problem or -- even better -- how to solve it? It's not a major problem to turn 3G back on manually, but i usually don't notice it's off until I've wait a minute or so for something to download.

I have a Droid X and am using Green Power and Juice Defender to help control the battery.

I'd think its because you have both Green Power and Juice Defender. They're conflicting. Remove one of them.

I'd vote you stay with JD. So much better, I love it.

I looked at some threads to determine which one to keep and found a number of suggestions that using either slowed things down, so I've uninstalled both and will monitor both the battery and my performance to see what happens.

I've used them for a long time now (First GP then now JD), they give me at least an additional 5-7 hrs standby time. However mind that they are effective only for people who are permanently connected to the internet with their data plans. If you aren't its better without them.

I use the Kindle app on my phone and several news apps several hours each day, so it's in use a lot. I usually wind up with about 20-30% left at the end of the day (though I carry a spare battery as a backup). I'll monitor my battery use and see what happens. If I have problems, I'll reinstall Juice Defender based on the comments here and try that.

I deleted both and haven't had any problems so far -- 4 days.
