Had the iPhone 7 for long tine now. The charger port loose, battery dies fast and now my hone button stopped working. Should I wait for iPhone 12 or just get a xr or 11?

sounds like you're forced to get a new phone regardless if possible by any means just get a refurbished XR for like 2-300 and skate off that until the next release comes.

If you don't have a budget and are well off financially then you might as well get it. There really isn't a good reason to buy the new iphone though. It doesn't have any groundbreaking features to justify it's price point. You could use an older iphone like the iphone 7 or 8 and you wouldn't be missing out on anything. The iphone 11 has a larger screen size, better battery life, better water durability, and faster speed/larger storage than older iphones. Those upgrades aren't massive gulfs at all, though. The differences would make such a small impact on your life that it's pointless.

Get a cheap one. Wait for 12.

Yes to buying new now, not seeing why you should hold on to a broken hardware for another year that just insanity

ebay bro.

your phone barely works and your asking if you should get a new one, yes unless you can't afford it

If you’re asking if you should, then you should..

You use your phone everyday, just get a new one and your quality of life will improve massively and that’s invaluable

If all that s*** worked, I’d say just keep it
