And most things that involve friction (e.g. tires and razors) will wear out with usage. It's hard to come up with something that is safe, effective, and will last a long time when its main use involves friction. Incidentally tires do last longer (and are safer) today than they did 50 years ago.
Back to the topic of smartphones, phones use much more power these days because of the many many apps that people regularly run that use power... Do you really need Zynga poker notifying you someone you know is playing RIGHT NOW? That takes processing power (and network usage), and therefore battery life... Get an app that will tell you what apps are sucking your power, and kill those apps...
