Greetings, I have a well kept iPhone 6S Plus for the past 1.5 years. That being said, as of late (iOS 10.3) my battery drain has been significant. I had it charge to 90%, then went for a 35 minute jog playing some music and then a podcast, which typically would drain a few percentage points but this time dropped to 10% and then to 1% in the matter of a short time. I will try to get a Genius Bar appointment but curious if there are other known issues/suggestions. This makes me want a phone with a replaceable battery and if I wasn't so glued to the iOS i'd happily consider returning to an Android based platform that is partnered with a manufacturer that allows battery replacement by the user. Thoughts/opinions?
