People always WANT the newest iphone or to have different updates that make their phone "cooler", but it is not necessary to update your phone every single time they come out with a new layout for the screen. However, updating your phone CAN be a need, sometimes it is needed for work if you are required to have an update that can only be held by the newest phone. Also, if your phone is old and glitching, it would be best to update it in case of an emergency.

It's hard to break a phone addiction, because that's what teenagers base their life off of... social media. To break MY addiction, I can get busy doing other things like spending time with friends or outside, instead of indoors on a weekend because I want to play a game on my phone.

in your family, you can also get your parents old phones as hand-me-downs. This is what I did with my family and I took their old phones once they got an update (usually from their company), and this worked well
