The iPhone 4 received largely positive reception, with critics praising its revamped design and more powerful hardware, in comparison to previous models. While it was a market success (with over 600,000 pre-orders within 24 hours), the release of the iPhone 4 was plagued by highly publicized reports concerning abnormalities in its new antenna design that caused the device to lose its cellular signal if held in a certain way.

The iPhone 5 featured major design changes in comparison to its predecessor.

The iPhone 6 and 6 Plus received positive reviews, with critics regarding their redesign, specifications, camera, and battery life as being improvements over previous iPhone models.

Reception of the iPhone 7 was mixed. Although reviewers noted improvements to the camera, especially the dual rear camera on the Plus model, the phone was criticized for the lack of innovation in its build quality. Many reviews panned the removal of the 3.5 mm headphone jack. -
Reception of the phones was generally positive, with reviewers praising the addition of inductive charging, fast charge capability, and the new Apple A11 processor, while criticizing the aging design that was introduced with the iPhone 6 and iPhone 6 Plus in 2014. -
The iPhone X received positive reviews. Its display and build quality were strongly praised, and the camera also scored positively on tests. However, the sensor housing "notch" at the top of the screen and the introduction of an all-new authentication method were polarizing for critics and consumers. The notch was heavily mocked by users on social media, although app developers responded.
