About the Apple iPhone 12
The Apple iPhone 12 marked a turning point for the standard iPhone line in October 2020, bringing an OLED display, 5G connectivity, and a flat-edged redesign to the non-Pro model for the first time. In 2026, it remains a functional budget option, though it sits in an increasingly tight spot. The A14 Bionic chip still runs iOS 26 and copes well with browsing, social media, messaging, and streaming. The dual 12MP camera takes respectable photos in good light, and Night Mode brings usable results after dark. 5G support gives it a meaningful edge over the iPhone 11, and the OLED display is a clear step up from any LCD-equipped iPhone. However, five-plus years on, the limitations are harder to ignore: the 60Hz display feels sluggish next to modern phones, the Lightning port is a growing inconvenience, Apple Intelligence is not supported, and battery health on used units will have degraded. At refurbished prices around 150 pounds, the iPhone 12 still offers solid value as a no-frills daily driver for light users or a reliable backup phone, but buyers should have realistic expectations about its remaining useful life.
