There's a growing trend when it comes to our smartphones and battery life. As our devices get more sophisticated, their uptimes get conversely smaller. There are two immediate ways to get around this hunger for power. You either start bringing along power banks or power cases, or you hope that your OEM starts putting in larger batteries, in which case the smartphone itself gets larger. Apple, however, isn't giving in to the trend and is keeping its smaller, non-removable batteries. Why? Because you wouldn't want to a larger battery. Or so says Apple's Jonathan Ive.
