iPhone 16 vs iPhone 15: A Detailed Comparison

iPhone 16 vs. iPhone 15: Key Differences Explained

From the front, it can be hard to tell Apple's phones apart, despite big differences. Is the iPhone 16 worth the extra cost, or should you save with last year's iPhone 15? We'll help you decide.

Another iPhone release, another potential upgrade.

If you have an iPhone 15, you might be wondering if it's worth swapping for the new iPhone 16. And if you have an older or non-Apple device, you may be debating whether to get last year's iPhone at a discount or pay full price for this year's model.

Starting at $799, the iPhone 16 represents the biggest upgrade Apple's baseline phone has received in years. It has a larger battery, a new ultrawide camera, two new hardware buttons for shortcuts (the Action button and Camera Control button) and it will eventually receive Apple Intelligence.

But at $100 less, last year's iPhone 15 still has plenty to offer including good cameras, a decent battery life and the ability to run iOS 18 -- sadly, it won't get Apple Intelligence though.

Here's a comparison of the key specs on the baseline iPhone 15 and iPhone 16 to help with your decision making. 


Prices and storage

The nice thing about new iPhone releases is that older models get a price drop. 

Thankfully, Apple didn't raise prices with the debut of its iPhone 16 lineup, and you can still get the baseline model starting at $800. If you'd rather save some money, you can now get last year's iPhone 15 for $700.

More specifically, with the iPhone 16, you'll pay $800 for 128GB of storage, $900 for 256GB of storage and $1,100 for 512GB of storage. 

On the iPhone 15, you'll now pay $700 for 128GB of storage, $800 for 256GB of storage and $1,000 for 512GB of storage. So same storage options for $100 less. Neither phone comes with expandable memory.

Cameras: Seeing double

Apple's iPhone 16

One of the most obvious differences between the two phone's is the iPhone 16's vertically stacked rear cameras. On the iPhone 15, the cameras were mounted diagonally.

The iPhone 15 features a 48-megapixel wide and 12-megapixel ultrawide camera, while the iPhone 16 has a 48-megapixel wide camera and a new 12-megapixel ultrawide camera. Despite the similar megapixel count between the two phones, the ultrawide camera on the iPhone 16 can take in more light, has a wider aperture and features autofocus for macro shots -- great for those who let the camera "eat" first.

Both phones have a 12-megapixel front-facing camera and can shoot 4K video. The main difference is the iPhone 16 can shoot 1080p spatial video at 30 frames per second, (hence the vertical stacking of the cameras on this year's iPhone 16 and 16 Plus).

Displays, size and weight

Both the iPhone 16 and 15 have an OLED screen with a 60Hz refresh rate. However, Apple updated the Ceramic Shield covering on the 16's display, which it claims is even tougher.

Apple implemented more modest tweaks when it comes to displays. The iPhone 15 and 16 both have 6.1-inch OLED displays with a 60Hz refresh rate, though the iPhone 16 doubles the 15's peak brightness, reaching 2,000 nits. Both have a 460ppi pixel density. 

The iPhone 15 and 16 are the same size, with a height of 5.81 inches, width of 2.82 inches and a 0.31-inch thickness. They weigh just about the same: the iPhone 16 is 170g (6 ounces), while the iPhone 15 is 171g (6.02 ounces). 

The iPhone 16 comes in black, white, pink, teal and ultramarine. The iPhone 15 comes in black, green, yellow, pink and blue.

Both phones feature Dynamic Island, and use Face ID or a passcode to unlock (no fingerprint scanner).

Battery, processors and software

Both iPhones have a USB-C port with USB 2.0 data speeds.

Apple doesn't disclose its battery capacity but says the iPhone 16 has up to 22 hours of video playback (18 hours streamed). The iPhone 15, meanwhile, has up to 20 hours of video playback (16 hours streamed). Both feature USB-C charging. 

The iPhone 16 supports MagSafe wireless charging up to 25 watts with a 30-watt adapter or higher, while the iPhone 15's MagSafe charging reaches 15 watts. They also each support Qi2 charging, up to 15 watts.

The iPhone 16 sports the new A18 chip, while the iPhone 15 has the A16 Bionic chip. The iPhone 16 has iOS 18 out of the box, and though the iPhone 15 features last year's iOS 17, it's eligible for the new operating system. 

New features on the iPhone 16

Apple Intelligence has been the company's key focus over the last several months, but you'll need an iPhone 16, rather than the baseline 15, if you want to tap into those upcoming AI features. (The iPhone 15 Pro models will also work with Apple Intelligence, but the company has since discontinued those phones.)

Apple has also added the Action Button to the full iPhone 16 lineup, as well a Camera Control button
