How do they know how to contact? Especially with the buying and selling of phones through third parties.
They will contact the buyer on record. If that person resold the phone that isn't really Apple's issue.
I wonder how that works with the consumer laws in the UK etc. Those laws say that it's up to the seller to replace/repair units they sold that they know or it turns out were crap at time of purchase. Which is easy enough when the manufacturer is the seller and openly admits you got a bum unit. But applying consumer law, is that claim only good between seller and original buyer.
What I mean to say it, strictly looking at the consumer laws, if John Smith buys an iPhone from Apple and sells it to Joe Blow, does Mr Blow have any grounds to apply consumer law against Apple or does he have to go back to John Smith. Even if Apple has admitted some units are bad and Mr. Blow's serial is of that batch can he apply consumer law against Apple as the seller if say he doesn't get the memo and turns up with a dead phone a day after warranty so that doesn't just cover it.

Yep. I've also done all the usual BS: restored as new, lowered screen intensity, turn off wifi when not in the home, turn off cellular when not on the road, disabled background app refresh and pretty much everything else suggested on the web. It's definitely 7.
Until you go to Apple and they say there is no issue with your battery hardware you really can't say that it is 'definitely 7. Could be a worn/defective battery and it was just the added stress that caused it to be more noticeable. Or just that you were paying more attention because of the software update.
