Background: I've got an iPhone 4 and it is painfully slow on iOS 7. I bought it while the 4S was the flagship model being sold. It seems that around the third iOS update, an iPhone's speed is severely reduced. Noticed this on other iPhones as well. So seeing that a 5C has similar specs to an iPhone 5, I only wonder if the same thing will happen a few years down the line. If iOS 7 on the iPhone 4 wasn't that bad, I wouldn't be posting this. But it really is terrible/unusable. Honestly, I'd rather be on old software than new but slow software. I used to praise Apple for still rolling out software updates on older devices (opposed to Androids) but now I question its worth. Going to call AT&T and see if they can move my upgrade date up by 5 months. Otherwise, I'm seriously considering taking my business to T-Mobile just to get rid of this phone.
