Answer:
Well your gonna want to state your main topic ,iPhone 11. I don't know how many paragraphs you did but you would then state each paragraphs topic. Then conclude your whole essay.
Here is an example (i took it from my own essay):
Most people have at least one hero. I have one. One hero. I didn’t realize it until I was asked who is your hero and “Shawn Johnson,” “ Shawn Johnson!” was blaring in my head. And I began to think about it, and body image, unhealthy way of living, and quitting for a good reason popped in my head. I hope your heroes made a significant impact on you as mine did for me!
This is for a hero essay, not a review so you would make the changes to fit your type of essay.
