By keeping the Smart Battery Case for iPhone 6s light, and making it smart, Apple’s offering an alternative for people who just want some extra battery life. Not all the time, but for when they’ll be using their iPhones more heavily than usual or for when they’ll be away from power for longer than usual.
I held off a few days with sharing my opinion on this new case. It’s a bit weird, kind of ugly, and seems to have some different compromises from competitors’ products. After reading this, there are some good arguments for the way Apple designed this case. It’s a very very simplified approach, and should be a nice alternative for people that want some extra battery life without having to worry about maintaining their battery case. I’m rarely that far from a charger and usually get through a whole day on a charge anyway, so I probably will not be getting one, but it’s nice that there’s an option, and it might challenge other manufacturers to try some new things.
