Just a quick note about my experience with my iPhone 6's battery. I purchased it Friday afternoon and through Sunday my battery life was pretty bad. 3 hours of use (web browsing, some youtube) would take the battery from 100 to 30. It that was not continuous use. So Sunday night I drained the battery completely and then put it on the charger all night long. Monday morning through Tuesday morning (about 24 hours), my battery went from 100% to only 55% with moderate use of browsing, youtube, email, phone calls, messaging. I call that a win in my book.
