I am also suddenly seeing severe battery drain on my Razr and its driving me crazy! I can't even make it thru a 12 hr shift at work and that is with a few times hitting the power button to check the time (its my watch at times) and sending about 5 texts back and forth. That is crazy! Still on ICS and not rooted. So I've been trying to figure this out and the only big change is switching from imo to IM+ as my im app. That switches to push after 1 min of not using the app and doesn't really make much of a dent in the list of things using the battery. What I have noticed, however, is that every time my phone drops and regains 4G, it turns the screen on, even tho I'm on my Wi-Fi . I'm close to the edge of 4G at my house, so even while typing this it prob happened 2-3 times and I currently have only 2 bars. I'm sitting 6 ft from my router and nothing else is running on the Wi-Fi right now, so this screenshot makes no sense either. Help?!?

I am experiencing much worse battery life after the Jelly Bean update as well. My two biggest culprits are Media and Android OS, both using much larger amounts of power than the screen, which was the biggest user before the update. I tried force stopping the media app and clearing cache, but that only helped for a day. Any ideas of what Media is and why its using so much power now?
I suggest to anyone experiencing worse performance after the update to do a factory reset. It worked wonders for the HD after the JB update.

My Maxx would have made it an estimated 12 hours yesterday, and the ONLY thing I did all day on it were use the Facebook app (and force close upon exit) and use the browser (again, force close upon exit). I did a factory reset and it hasn't really made a difference in the battery life, although it straightened out the phone issues I was having.
