Apple's Smart Battery Case juices iPhone, drains wallet
The iPhone 6S is great, but its battery life was never its strong suit. I said that in my review, and I felt the same way about the iPhone 6, too. I pair multiple fitness bands and smartwatches, stream music and generally wear out my iPhone so that it always needs a top-off charge by 4 p.m.
Apple has danced around the battery limitations on the smaller 4.7-inch iPhone, adding a low-power mode in iOS 9 (which stretches battery life a bit) and pushing power-hungry users to the larger, more capacious 5.5-inch Plus phones -- whether or not they preferred its jumbo size. Third-party accessories have long addressed the battery issue, meanwhile, with everything from pocketable battery dongles to form-fitting battery cases.
