«Depending on extent of functionality, feature phones
may have many of the capabilities of a smartphone, within certain cases. For example, today's feature phones typically serve as a portable media player, and can have digital cameras, GPS navigation, Wi-Fi and mobile broadband internet access, and mobile gaming through discrete apps. However, feature phones have weak batteries and processors and therefore, video games are rudimentary. Digital cameras, microphones, and speakers are usually are of very low quality.»

Many basic phones now include some of that functionality,
rendering them as either basic feature phones or smart feature phones—whereas advanced feature phones include all of these and more, but may entail certain other sacrifices at the consumer end.»
