I'm not sure why anyone would downvote you for this sensible, quality post but I did because I know how rewarding it can be to predict something and then have your prediction come trueOne part is environmental, another part is "score keeping". Some people would rather tout 98% battery life after 1 whole year doing trickle charging versus 89% and constantly wired. It doesn't particularly save anything though, if it means updating the phone every 1 to 2 years. (here comes the downvotes!)
