How to say 'I wouldn't like one' in French?

How do you say either 'I wouldn't like one' or 'I don't want one ' in French?
For example 'I don't have a job and I don't want one until next year' or 'She has an iPhone but I wouldn't want one'

It's really where to put the pronoun (the 'one' part) that I'm having difficulty with, so if it's possible could you also explain the answer as well?

Je ne voudrais pas un.

"I don't have a job and I don't want one until next year"
= "Je n'ai pas de travail et je n'en veux pas avant l'année prochaine"
>I don't want one = Je n'en veux pas / I don't want… = je ne veux pas.

"She has an iPhone but I wouldn't want one'"
= Elle a un Iphone mais (moi) je n'en veux pas.

I can't explain it with words but I guess you could understand with these examples.

  • Wouldn't turning off iPhone while charging shorten battery life? They say the iPhone has a battery life of 400 full charge cycles before it starts its decline. Ok here is the thing… A lot of talk on how to save battery life on the iPhone by charging habits such as turning the phone off while charging, airplane mode while charging, turn off Wi-Fi bluetooth etc… But if the phone charges faster… Wouldn't that increase the amount of full charge/discharge cycles and there for decreasing the life of the battery?
  • Why wouldn't my laptop connect to the Wi-Fi? I was on my iPhone this morning and the Wi-Fi was working normally, but when I powered up my MacBook Pro, it said it was unable to connect to the Internet and wouldn't load any pages, yet the Wi-Fi on my phone was working fine. I checked everything, it was all normal, so I just restarted my computer and the Wi-Fi was working. Why did it do this? It's never done this before. This laptop is also brand new and shouldn't have a problem connecting to the Internet
  • What are the names of French Games? Are games on the IPHONE/ANDROID LIKE Angry Birds Doodle Jump Temple Run DO they have the same name in English and in French SO would a french person say… Apres que je finirai les devoirs, je jouerai le jeux de <<Angry Birds>>
  • I had to restore my iPhone because the iPhones store app wouldn't show up in any of my apps. Now that I restored it I have to download? All of my music again. When I click on the clouds to download it the spinning circles will come up and act like its gonna download for a little bit but then just stops and goes back to the clouds. None of my music will download. And my phones acting up now. Does anyone know how to fix this?
