This is one of the most common questions new iPhone 13 series buyers have since both phones are the same size, have the same processor, and have other specs that match each other. The available colors are different and the iPhone 13 Pro has one additional camera, a 6x optical telephoto camera. While there is 2x optical zoom on the iPhone 13, the 13 Pro also supports LiDAR technology. The iPhone 13 Pro also has a 120Hz high refresh rate display, which is probably the single best selling point for the 13 Pro over the standard 13, assuming the above camera differences didn't sway you. If you've ever felt like you could actually see the individual frames of your iPhone's display being refreshed, or you crave the buttery smoothness of similarly equipped iPads that support Apple's ProMotion technology, then by all means opt for the Pro on this feature alone. If you're unsure, I'd highly recommend visiting an Apple Store or other retailer that will let you take a side-by-side look at the displays in action. Scroll through something quickly and see if you can notice a difference in smoothness. If they look the same, save yourself some money and go for the iPhone 13.
