Juice defender application on your device; Good or Bad? To each according to their need...but for me, I had to remove/uninstall this app from my phone (Htc Evo 3d). I noticed since installing juice defender most of my data usage applications wasn't operating as they did before...Example: Pandora radio(stops every other song searching for coverage), Gmail and Yahoo emails would arrive 2hrs after being sent(they took longer than the occasional 15 to 20min., plus a few other applications that didn't seem to be working as they normally did before. Whoever getting better battery consumption and greater overall performance since installing this app _ Kudos to you. Juice defender may be a good app, but it doesn't seem to work well with my phone.
