I had planned on skipping the iPhone 7 entirely, but the battery issues on my iPhone 6 got worse this past week prompting me to buy a new iPhone. For the better part of the past year and a half, my iPhone 6 would, from time to time, have substantial battery drain within a few minutes while the phone was either idle or while I was doing something trivial like typing an e-mail in Mail.app or browsing the web in Safari. Usually, the phone would drop about 10-15% within about two minutes -- sometimes sooner. It didn't happen everyday or even every week -- maybe two or three times per month. As soon as I plugged the phone in, the battery charge would jump up 10 to 12 percent. On two different occasions this past week, the phone dropped immediately from 80-90% to 1% and then proceeded to power off. As soon as the phone was plugged back in, it turned on and registered the charge as being within a percentage point or two of what it had been when the phone suddenly dropped to 1%. I don't feel right about selling the iPhone 6 to another person given the battery issues. My plan is to trade the phone in with Apple in exchange for an Apple Store gift card. This is the first iPhone I've had that's had this problem; and I've had iPhones going back to the iPhone 3G in 2009. I'm annoyed that Apple has yet to acknowledge an issue with iPhone 6 batteries. The behavior I experienced recently seems to fit what some iPhone 6s users have been seeing that prompted Apple to start the replacement program.
