I flashed mine day of release with odin, noticed no difference in battery life however I now have an annoying bug that occasionally happens, the screen rotation will stop working, you could find that your stuck in portrait or landscape when browsing net or viewing youtube vids, to fix you must reboot phone, hope this bug is fixed in next update.

Did you guys do a factory reset after updating? My screen on time has gone from 6-7 hours to 4-5

I only factory reset if it's a step up in Android version but with mine recently I installed a custom rom which i didn't like so did a fresh install and restored my apps and data from titanium backup. Not sure if it makes a difference but I like to clean my phone every now and again

just got DMB" Media Scanner is killing the hell outta my battery using 88%
