Can I use my Mac Book Air's Apple care+ on my iPhone 5?

I bought a Mac book at christmas time and took out the apple care + for it. Recently my iPhone 5 has been struggling to work. Could I transfer the apple care onto my iPhone and get it repaired cheaper that why?

No, AppleCare can't be transferred between devices.

You can only get AppleCare+ on your iPhone if you purchase it specifically for your iPhone within 60 days of purchasing the iPhone.
