It seems to work on the Gingerbread leaks. I have been running for the last month or so and it was great. I switched back to EE4 due to the static issue while on a call and juice did not work well at all. I am on EP3 right now and it seems to be working just fine. Static is hit and miss though...
I had JD on my DroidX, had great success with increasing battery life. I was hoping that HD on my Charge would let me squeeze a little more from the battery, but sadly I found the same thing, the data connection wouldn't turn on. I even tried the option included in JD to toggle the Mobile Data Connection, but no success. I ended up disabling the app and all is working well now. I hope JD developer can work around this issue in a future release.
Are you on EE4 or a GB leak? Froyo EE4 did not work for me but on Gingerbread, my 4g and 3g come back as expected with Juice Defender. I am on the EP3 debloated rom currently.
Not really as the stock ROM causes the problem, using a ROM to GB would fix the problem, all info ad per the JD developer. Im stock as well as confirm the problem with stock.
