Re: it’s for 18 months, maybe two years,
SOGA was updated/replaced in the UK by the Consumer Rights Act in 2015.
Timing is tricky. I'm not sure your blanket '2 years minimum' is stricty accurate. It's an EU directive and doesn't overrule SOGA/CRA. It depends on what has happened, when, and where the burden of proof lies, the vendor or purchaser. The time limit can be reduced to not less than a year if agreed between seller and purchaser (most likely there in the small print) Plenty of reading online about it.
Issues under a year are usually straightforward, over a year less so with a normal maximim limit in the UK of 6 years.
"If a fault develops after the first six months, the burden is on you to prove that the product was faulty at the time of delivery."
There's the kicker. Have as long as you like, but prove it....
Yes, a lot of warranties are overpriced, high margin, upsells and usually barely worth the paper they are printed on.
Knowing your law & rights, along with plentiful patience and perseverance, is better value. It's saved me a few bob.
I've wondered for a while why no one has brought a challenge against phone makers for non replaceable batteries.
Satisfactory quality. I reasonably expect a higher value item to last longer than a cheap one. I don't think it is unreasonable for my expensive mobe to last me for 3-4 years. My S6 is 2 years old and no noticeable performance issues, barring a dying battery. I'd expect it to last a couple more years. In which case either the battery has to do the same, or should be easily replaceable.
No cure, no fee, anyone? It's got to beat ambulance chasing.
