In EU warranty law, basically it's very simple. If you buy a product and have a defect in one year, the defect is considered being present at the moment of sale. The person/company who sold you the product have to repair/replace the product within a reasonable time frame, unless they can prove that the defect is caused by you.I really want to know how EU warranty laws are going to work with this? Does someone just have to plug in a USB Port killer to get a new device? I am asking a real question because I honestly don't know. What determines manufacturer defect vs abuse?
If the defect occurs between 1 and 2 years, the person/company who sold you the product have to repair/replace the product within a reasonable time frame, but only if you can prove that the defect did occur without any wrongdoing from your side.
This is the minimum law within the EU regarding warranty. Member states however are free to divert from it, als long as it is not less than the minimum law. I'm dutch and in my country the law states that warranty is only limited by the expected lifetime of the product. So if Apple is selling iPhones with a life expectancy of 5 years (as they offer iOS updates for 5 years), the warranty period is also 5 years. Unless of cause Apple wants to state in a courtroom that there products only last 2 years. After 1 year, I of cause have to proof that the defect isn't caused by my wrong doing.
Sounds nice, but normally it means that if your iPhone dies after 3 years of use, without any obvious cause, you just replace it. Nobody is going to spend time and money on a 3 year old device.
So if you, as you put it, plug in a USB C port killer and you do this within one year after buying the product, Apple will have to prove the defect wasn't present when you bought the device. Something they probably can do very easy, as putting to much power on electrical components will always leave marks. After that year, you need to prove that the defect wasn't your fault. You only can do that by having an independent researcher looking into it. They (probably) will find of cause traces of to much electrical power on the phone. Which means you lose the case an can pay for it all yourself. Again, it's not worth the price of an iPhone.
If you want to read for yourself:
Directive (EU) 2019/771 of the European Parliament and of the Council of 20 May 2019 on certain aspects concerning contracts for the sale of goods, amending Regulation (EU) 2017/2394 and Directive 2009/22/EC, and repealing Directive 1999/44/EC (Text with EEA relevance.)
Ow and of cause the usual general disclaimer: I'm not working for the court system/law firms etc. Nor do I hold any degree regarding practicing law that should give one the idea that I should know more about laws than any other common man. If you start doing stupid things after reading this post, they are, well, your stupid things. Therefore only you will be responsible for them.
