After three years, iPhones received another redesign, but it was something we had in the past. The iPhone 12 series brought back the flat-edged glass sandwich design of the iPhone 4. Then, there was a smaller — iPhone 12 mini — which packed the same punch as the bigger iPhone 12. The two were similar to the iPhone 11, but the iPhone 12 models came with an OLED display, a better chip with 5G connectivity and MagSafe charging for iPhones. Also, this was the year when Apple introduced fast charging on vanilla iPhones and got rid of chargers from the box for iPhones.
