The iPhone 15 and iPhone 15 Plus are Apple's latest standard iPhone models, sporting some bigger upgrades than seen in recent years, but how different really are they compared to 2021's iPhone 13?


Apple released the ‌iPhone 13‌ in late 2021 and has bumped it down in price since then to make it more accessible as new models have been released, and it now starts at just $599. The latest models, the iPhone 15 and iPhone 15 Plus, start at $799 and $899, respectively.

The iPhone 14 and iPhone 14 Plus sit in the middle of the iPhone lineup at $699 and $799, but since the upgrades that these devices offer over the iPhone 13 are relatively small, a significant number of users may now be weighing up whether to get the iPhone 13 or the iPhone 15, and skip over the iPhone 14 in their considerations. Likewise, existing iPhone 13 users may be wondering what there is to gain by upgrading to an iPhone 15 model.

Our guide helps to answer the question of how to decide which of these two iPhone models is best for you, and serves as a way to clearly see the differences that the iPhone 15 brings to the table. This article focuses on the iPhone 13 and iPhone 15, but to understand the differences between the iPhone 14 and iPhone 15, see our other buyer's guide:

The iPhone 13 and iPhone 15 both feature the same improved water resistance, Ceramic Shield glass, 12-megapixel ultra wide camera, support for MagSafe accessories, and more. The iPhone 15 offers a large number of substantial upgrades, such as the Dynamic Island, USB-C port, and 48-megapixel main camera.

The iPhone 15's upgrades over the iPhone 13 are substantial, offering a more refined and appealing design with contoured edges, frosted back glass, and the Dynamic Island. Features like the brighter display and USB-C port are meaningful quality-of-life enhancements that all users will be able to take advantage of. The 48-megapixel main camera, 2x optical zoom option, next-generation portraits, Smart HDR 5, and improved Night mode also make for a significant overall camera improvement for average users. Iterative changes like the A16 Bionic chip and support for Qi2 are also welcome refinements.

Existing iPhone 12 or iPhone 13 users should certainly consider upgrading to the iPhone 15 or iPhone 15 Plus, but it is not essential. Users of the iPhone 11 or older still have much to gain by upgrading to an iPhone 13, especially if budget is an important limiting factor, but the iPhone 15 will be a much more worthwhile upgrade if you can afford it. The iPhone 15 has a range of improvements that are likely to make it age better and be slightly more useful over time, warranting its higher price.

For everyday users, it is important to remember that the switch to USB-C on the iPhone 15 will make any Lightning cables and accessories you have redundant, meaning you'll need to purchase a $29 adapter or use a new cable. If you're coming from a much older device, you will also likely need to buy a new power adapter. If you are unhappy about this change, then it may be worth sticking with what you have for another year or the iPhone 13, but it is worth highlighting that the switch...

I quibble with the word "substantial". Not saying it's not more advanced, but if these are the only real differences between the 13 and 15, I'd like to see the 14 slotted in there. Sure, if I were buying fresh, I'd probably go 15 over 13, but I don't see anything generally compelling to consider updating from a 13. Crash detection and maybe the photo/camera stuff (but I don't really take pictures or videos) might be about it. Everything is, to me subjectively anyway, is a difference that doesn't really make a difference.
