Feature phones are not running on general purpose OSs and are not capable of half the things smartphones can do. So there actually is an order of magnitude difference between energy consumption, resulting in longer battery life. But since their functionality is way different than a smartphone’s, it is akin to measuring the fuel efficiency of a horse and a car.
Wrong. KaiOS runs on featurephones and has a lot of the features people want from a handheld device: listening to music, messaging, social, even directions. KaiOS has a store where anyone can distribute their own apps.
