@hboon it's much better now that I turned off location services for apps that don't 'need' it. Also, location-based reminders obviously suck battery life. Certainly it's not as good as iPhone 4. Seems to be a consensus that if you happen to have any 'corrupted' Contacts in your Address book that when you Link to iCloud, it will continuously sync contacts ad infinitum, so that'll kill battery 4 sure.
