Meanwhile, the new iPhone 12 Mini, measuring just 5.4-inches and possibly housing a midrange B14 chip, rather than Apple's A14 SoC, starts at $699 for a 64GB model ~ the same price as the iPhone 11.
According to Pu, the price hike is primarily because of the addition of 5G and an OLED display, which feature on all iPhone 12 models, while the iPhone 11 is only 4G and has an LCD display.
