Got the new IP7+ last weekend at the local Apple store via IUP, but I'm having horrible battery life on this phone. It's constantly draining battery even sitting at idle. I've tried turning off all background refreshes and location services but still the same result. Instead of getting an additional hour of battery over IP6S+ like Apple advertises, I'm getting about 30-40% LESS battery life than my previous IP6S+. I'm thinking it's a hardware issue and would like to just return and re-buy instead of going through Genius Bar and getting the phone replaced. Has anyone done this before? After return the phone in store, does Apple allow immediately sign up a new IUP? Thanks and appreciated if anyone can share their experience dealing with IUP.
