How long will my iPhone 5S remain fast and smooth?

I got an iPhone 4 as soon as it came out and took great car of it for about 3 years. But after two years it started to become slow and after I hit 3 years, it was almost unusable because it couldn't handle ios 7. I know we can only estimate but since the iphone 5S is A LOT more powerful than the iPhone 4, should it last more than 3 years and hold up well?
