You're not getting it. There's two different strategies here.
Apple's strategy is to take their current flagship and move it down the pricing tier when the next phone comes in. So now it's iPhone 6 + (most expensive), iPhone 6, iPhone 5s and iPhone 5c (cheapest); previously it was iPhone 5s (most expensive), iPhone 5c, iPhone 4s (cheapest).
Samsung makes one flagship, takes away last year's model, and introduces a range of variations on that one phone. So at the same time that the 4s is being sold, the equivalent priced iPhone is the 4s; and currently the equivalent to the S5 Mini is the 5c. That's how you need to compare pricing at any point in time.
I'm talking about release dates. Apple is like now, late September, and Samsung is February.
