As of my knowledge cutoff in September 2021, the iPhone 14 has not been released yet, so I cannot provide a comparison between the two devices. However, based on Apple's typical release schedule, the iPhone 14 is expected to be released in the fall of 2022.
When it comes to the iPhone 13, which was released in September 2021, it has a few key differences compared to the previous generation iPhone 12. Here are some of the main differences:
Design: The iPhone 13 has a slightly redesigned camera bump, which is now diagonal instead of vertical. It also has a smaller notch at the top of the screen.
Display: The iPhone 13 has a brighter Super Retina XDR display compared to the iPhone 12, and it also has a higher refresh rate of 120Hz.
Cameras: The iPhone 13 has improved camera capabilities, with a new cinematic mode for video, better low-light performance, and improved image stabilization.
Battery life: The iPhone 13 has a longer battery life compared to the iPhone 12, with up to 2.5 more hours of battery life on the Pro models.
Processor: The iPhone 13 is powered by the new A15 Bionic chip, which is faster and more efficient than the A14 chip in the iPhone 12.
Overall, while the differences between the iPhone 13 and 12 may not be huge, they do represent incremental improvements in key areas like battery life, camera performance, and processing power. As for the iPhone 14, we'll have to wait and see what new features and improvements it brings when it is eventually released.
