How do I convince my parents to get a iPhone 6?

My android phone that I've had for two years is broken now, my friends from school have suggested that I get an iPhone 6. I don't want the new iPhone 8 or iPhone X or an iPhone 7, I just want an iPhone 6. I feel horrible for asking my parents to buy expensive things for me because I feel like a spoiled brat and feel ungrateful for the things I have. I just want a faster and better phone with a good camera quality. I feel like I've proved to my parents that I'm worthy of a good phone, I've made it into a position at a credit union at my school, and have outstanding grades. Please, any tips?

You will have to make a good case in favour of your desire
without stating your desire.

In other words, explain the benefits your Parents would receive if you had an iPhone6
compared to what They would (and would not) get if you Didn't have an iPhone 6.

Rotsa ruck…

Then get off your *** , get a job and earn a new phone. Otherwise, don't ask for an expensive one, ask for a cheap one.

Believe it or not, people survived for millenia without cell phones.

If you need it just tell your parents and give them what they want you to do as a return

Offer to pay half of the phone. If you don't have any money, well try to work something out with them.

And just so you know, you don't "need" a cellphone for high school. You think you do, but you don't. I went through high school (2011-2014) without a cellphone.

Don't. Iphone, smartphones in general, cause more problems than good.
