I'm considering buying Apple Care for $99 for my iPhone 6. It includes free battery replacement for battery depletion of 50 percent or more from original specification for up to two years after the purchase of the iPhone. Typically an Apple battery replacement would cost $79, so if I do get my battery replaced the $99 for Apple Care+ is well worth it considering the peace of mind from the accidental damage protection Apple Care+ provides. Before I make the purchase I'm trying to gauge how long I can expect my iPhone 6 battery to last. Apple says, "your battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles." With my phone battery in good health I typically use a little more than one charge cycle per day. So assuming that in 365 days (1 year) I'll use 400 charge cycles, my battery will have less than 80% of its original capacity approximately 15 months after I purchased the device. The unknown factor is how rapidly the battery health will deplete after I hit 500 cycles. With all the devices I've owned previously the battery has been very good for the first year and a half, but after that the battery health degrades rapidly. For example, when I first bought my Nexus 4 I almost always was able to go 8 hour off the charger, and it wasn't at all unusual for me to have 12 hour days with more moderate usage. Some 16 months after I purchased the device, with typical usage I'm lucky to get 4 to 5 hours off the charger and even when I hardly touch the device, its batter is depleted to about 50% after 6 hours of the charger. This degradation in battery life happened strikingly quickly. My friend with an iPhone 4s had similar experiences. My question for you guys is how was the battery life of your devices after two years and how frequently you charge b the device. This will greatly assist me in deciding if I should purchase Apple Care+.
