For example, if a laptop battery loses a fraction of its capacity during these two years, it's considered normal wear.
But if the battery dies and needs replacement, it's not a cause of wear, because batteries are expected to last more than two years. So this is covered by the 2year warranty.=
A laptop battery is expected to last a certain number of charges, not a number of years. Four years ago, MacBooks used batteries that were expected to last 300 charges, now they use batteries that are expected to last 1000 charges.
It would be hard to achieve, but if you manage to get 1000 charges in a year and the battery dies, I don't think that is Apple's problem. But most people wouldn't be anywhere near 1000 charges in two years, and in that case I would consider a dead battery to be defective.
You need to understand what the EU warranty is: "covers original defects shipped". Apple care covers almost everything. Beyond the 1st year, Apple has no obligation to service your machine for free
Just to make this clear: A product can have a defect and still work fine for a while, but the defect can lead to the product breaking much earlier than it should. It's quite simple: If something breaks, it is either (a) normal wear and tear, or (b) you or someone else broke it, or (c) it broke because it was badly made and therefore defective.
I live in Italy, and yes Apple has always been ambiguos about the warranty on its products claiming 1 year warranty instead of 2. I can see that this is an Apple forum of Apple fans (as am I) but I can't understand why people prefer to defend Apple instead of customers legal rights.
Because all these people claiming Apple has to give 2 years warranty are confusing warranty with statutory rights. Apple (the manufacturer) can give you as much or as little manufacturer's warranty as they like. The store where you buy is responsible that the product is of reasonable quality, and usually that means it shouldn't stop working within two years.
APPLE should do the right thing and clearly and unambiguously explain this to their European customers, and adjust their European warranty coverages accordingly.
Have a look at the UK website (store.apple.com/uk). Apple does indeed explain what rights its customers have - especially that _the seller_ is responsible for the quality of the product, which includes Apple being responsible for non-Apple products that you buy at an Apple Store. Apple does _not_ have to change its warranty in any way. The consumer rights against Apple that you have if you buy any product from an Apple Store (the important thing being not whether you buy an Apple product, but whether you buy from an Apple store), you have those rights without Apple saying anything about it.
