So this morning I started to use my fully charged iPhone7 and noticed battery life was draining fairly quickly. Faster than it ever did on my iPhone 6. It also started to feel warm. I went to Settings>Battery and noticed the Home/Lock Screen used 48% of the battery. Anyone know why this is happening and how to stop it? Also the phone getting warm, I'm not sure if it's related to the battery drain situation. I'm grateful for any help of guidance.
