Is it worth upgrading from the iphone 4 to iphone 5c?

I have a plain old iPhone 4 white 8 gb is it worth upgrading to a iPhone 5c green 16gb

Well the 5 has a faster processor (though not as fast as the 5S) than the 4, you're talking about more memory than your current phone and it's the low-cost phone of the 5 line.

So it may be worth considering.

If your phone is doing everything you want, wait until you "need" a new phone, then you can get a better phone. So you can wait until you get an iPhone 6 or 7 or whatever newest coolest phone is at the time.

You can got crazy and maybe broke, if you try to always keep getting the newest mobile phones.

Yea…

Faster, lighter, more powerful
