iPhone 6 battery suddenly draining fast
I've had my iPhone 6 since the end of October 2015. Everything has been great, until recently. Suddenly, my battery drains A LOT faster than usual. I never let the percentage get below 50%, and I don't have many apps, the brightness is always halfway, and it's on DND overnight. I have AppleCare, but would they replace the battery or would I have to buy a new phone through applecare? Thanks.
