I upgraded from a note 3 to a note edge. Fiat couple days it was great on battery. Now is draining. I've had this issue with the last phone too. I'm starting to wonder if it's just my usage that causes the drain. I'm on my phone all day at work. What are the best tips to save battery life? I have the battery saving mode on hands the screen dimmed and don't have the extra features on. Anything else I can do?
