Tired of recharging your iPhone several times a day? That's just because the iPhone's thin and light design is encouraging you to use it more, according to Apple's design guru Jony Ive. In an interview with the Financial Times today, Ive dove deep into the design process of the Apple Watch, but when asked about the need to recharge iPhones often he didn't see much of an issue. Instead, he noted that stuffing in a bigger battery would make it heavier and less "compelling." Never mind that battery life remains the single biggest concern for most smartphone users, according to a survey by Cat. If this interview had occurred a year ago, Ive would seem even less sympathetic. Now, at least, Apple has the iPhone 6 Plus available, which offers a significantly bigger battery thanks to its larger 5.5-inch frame.
