Hello, I am posting here in hopes of figuring out my battery life issues with my iPhone 6s Plus. I have had the phone for about 3-4 weeks. It was set up as a new iPhone as I just switched from a nexus 5. I keep my brightness around 30-40%. Bluetooth is always off. Wifi is off as soon as I leave home. Nearly all of my apps have background data turned off. I have tried resetting the phone, and draining the battery completely and recharging. Yesterday I got 1hr 43min use and I was at 20%.
