Hows everyone's battery life? I had always heard the plus phones had great battery life due to the fact that hey have much larger batteries. However, so far I'm not particularly impressed by mine: This is an improvement over my iPhone 6, however, so many reviews made it sound like the phone would last more than a day with "heavy use". Mine made it to 4pm before I had to go plug it in. Are there any newer iOS 9 features I should be disabling to help improve battery life? Perhaps "hey Siri" or something outside of the regular battery saving tricks?
