And that's a surprise to whom? It's the same with smartphone and notebook batteries. Tell me, when was the last time, you actually got 9 hours of battery live (in case of a MBP)? Don't get me wrong, i see it the same way as you are, but this is an issue that you can find everywhere not just in car manufacturing. For example, a lot of power supply companies try all kinds of tricks to game the efficiency test systems.

In fairness, Apple typically understates battery life in marketing materials. Most new-model reviews show that clearly. And, if you got a bad battery that doesn't live up, they'll replace it at no charge. Battery life declines with age, however.

The consequences are different however, increased pollution has far reaching consequences, first of all human health. If my neighbour's smartphone has a shorter battery life it doesn't concern me, however if their car (and the cars of million of people around me) pollute more it's definitely my problem.

  All these little things add up though. Every device that gets less battery life than expected is taking more power to run. That power likely comes from a non-clean source. Given, it's not on the scale of the automobiles, but dismissing it outright may be a mistake.

MBP battery issue is a bit complicated, especially when discrete graphics is present due to switching issues with their in-house solution (no Nvidia Optimus for OS X). MBAs on the hand, I've seen them go past 13 hours easily (~1 year old, WiFi off, low-med brightness, editing documents).

Perhaps you did not read the article and responding to the title. The article points out that 1/3 of improvement in past 3 years to meet regulation requirements was real improvement and 2/3 was just manipulation. It doesn't matter that people drive cars differently than they are tested in cars, to illustrate it they highlighted that due to those manipulations that difference now can be as high as 50% which is beyond claims that people drive cars differently than when they are tested in labs.
