I use it to & although I did see an improvement on my Inspire, as well as on my One. You could also use your toggles to switch off what you do or don't need. Go into certain apps and have it sync when you open it. Or set the sync schedule.
Last week @ work I was able to go two days, before charging my phone. That's average use of mobile or WiFi, texting, email, calendar,Facebook & Twitter. Whether that had anything to do with JD or not, I can't complain!
Try it & see if it works for you. If not uninstall.
