Today, the day when Apple will unveil the iPhone 13 series, a survey conducted by research firm Consumer Intelligence Research Partners (CIRP) of 2,000 smartphone users in the states, reveals that iPhone units get traded in more frequently than Android phones. One-third of the iPhone handsets being used in a trade are being exchanged to reduce the price of an upgrade. That number could be inflated by the iPhone Upgrade Program which allows iPhone users to trade in their iPhone every year for the latest model.
