Design

The iPhone 17 is identical in design to the iPhone 16, but it is slightly larger. Instead of a 6.1-inch display, the iPhone 17 has a 6.3-inch display, making it the same size as the iPhone 17 ProAside from the size upgrade, there are no other design changes. The iPhone 17 measures in at 5.89 inches tall (149.6 mm), 2.81 inches wide (71.5 mm), and 0.31 inches deep (7.95mm). It weighs 177 grams. Compared to the iPhone 16, the iPhone 17 is a little thicker and it is seven grams heavier.The iPhone 17 models have an all-glass front and a colorful matte glass back framed by a color-matched aluminum frame. Colors this year include Black, White, Mist Blue, Sage, and Lavender.The Dynamic Island near the top of the display houses a front-facing camera and TrueDepth camera system for Face ID. Antenna bands are located on the top, left, and right sides of the phone, with a power button and Camera Control on the right side and volume buttons and the Action button on the left side.Speaker holes, a microphone, and a USB-C charging port are located at the bottom of the iPhone 16 models.

Apple did not change the camera design even though the other iPhone 17 models have an updated camera plateau.

Water and Dust Resistance

The iPhone 17 has an IP68 rating for resistance to water and dust intrusion. The smartphones are able to withstand a depth of up to six meters (19.7 feet) for up to 30 minutes.

In the IP68 number, the 6 refers to dust resistance (and means the iPhone 17 can hold up to dirt, dust, and other particulates), while the 8 pertains to water resistance. IP6X is the highest dust resistance rating that exists. With the IP68 rating, the iPhone 17 can withstand splashes, rain, and accidental water exposure, but intentional water exposure should be avoided.

Water and dust resistance are not permanent conditions, according to Apple, and can deteriorate over time as a result of normal wear. Apple's standard warranty does not cover liquid damage, which means it's best to use caution when it comes to liquid exposure.

Action Button

The Action button on the left side of the iPhone is customizable, and it can be set to perform one of several different actions in the Settings app.

• Focus: Activate or deactivate a Focus mode (Do Not Disturb is the default).

Display

The iPhone 17 has an upgraded Super Retina XDR OLED display that's 6.3 inches, up from 6.1 inches. It features a resolution of 2622 × 1206 with 460 pixels per inch. Apple made major improvements to the iPhone 17's display, introducing ProMotion display technology with up to a 120Hz refresh rate. 120Hz maximum refresh rates allow for smoother scrolling when viewing webpages and improvements for video. Apple also added support for Always-On display, which leaves the time, notifications, and widgets visible even when the iPhone is inactive.

Peak brightness is now 3,000 nits outdoors (up from 2,000 nits), with typical maximum brightness of 1,000 nits and peak HDR brightness of 1,600 nits. The display has a 1-nit minimum brightness for the Always-On display.Apple added a seven-layer anti-reflective coating that is designed to cut down on reflections by 33 percent to improve outdoor visibility. Other features include a 2,000,000:1 contrast ratio, wide color support for vivid colors, and True Tone. True Tone matches the white balance of the display to the ambient lighting for a paper-like viewing experience that's easier on the eyesThe display is protected by Ceramic Shield 2, an upgraded cover material that offers 3× better scratch resistance.

Dynamic Island

The Dynamic Island includes the TrueDepth camera sensor for Face ID and the front-facing camera. The display has a small circular cutout on the right side that's for the camera, and a pill-shaped cutout on the left side for the TrueDepth system for Face ID. Apple uses software to combine the two cutouts into one pill-shaped feature that makes up the Dynamic Island.

Apple turned the Dynamic Island into part of the iPhone's interface, and it is used as a front-and-center information hub for notifications and other at-a-glance information from apps and services. When you make an Apple Pay payment, for example, Dynamic Island expands into a square shape to show confirmation of your Face ID scan, and when on a phone call, it expands so you have phone controls at your fingertips.controls at your fingertips.

The Dynamic Island can display everything from Maps directions to Apple Music, and it integrates with Live Activities. There are no changes to the Dynamic Island with the iPhone 17.

TrueDepth Camera and Face ID

The iPhone 17 models continues to use Face ID, Apple's facial recognition system that is baked into the Dynamic Island.

Face ID is used across iOS for unlocking the iPhone, allowing access to passcode-protected apps, confirming app purchases, authenticating Apple Pay payments, and more.

Face ID works through a set of sensors and cameras. A Dot Projector projects tens of thousands of invisible infrared dots onto the surface of the skin to create a 3D facial scan that maps the curves and planes of each face, with the scan read by an infrared camera.

The facial depth map is relayed to the A19 chip where it is transformed into a mathematical model that the iPhone uses to authenticate identity. Face ID works in low light and in the dark, and with hats, beards, glasses, sunglasses, scarves, masks, and other accessories that partially obscure the face.

Front-Facing Camera.

The Dynamic Island also houses the new 18-megapixel front-facing camera, which has been upgraded this year. Apple is calling the new selfie camera the "Center Stage" front camera, and it has the first square camera sensor on an iPhone.

The square sensor provides a wider field of view that can capture more detail, so you can now take a portrait or landscape selfie while holding your phone vertically. Center Stage uses AI to expand the field of view and can rotate from portrait to landscape to fit everyone in the shot.

The camera supportsultra-stabilized videoin4KHDR,andI'mthereisanoption to record with the front and rear cameras simultaneously using Dual Capture. During video calls, Center Stage works to keep you stable and in the frame.The front-facing camera also supports Night mode, Smart HDR 5 integration, Dolby Vision HDR recording, Deep Fusion to bring out fine details, a Photonic Engine that improves low-light performance, and a portrait feature that lets you take images and turn them into portrait shots later.Along with 4K video recording, the camera supports QuickTake video, slo-mo video, Portrait mode, and Portrait Lighting, and the Photographic Styles feature for selectively applying edits are also supported on the front-facing camera.

A19 Chip

The iPhone 17 uses Apple's A19 chip, which is built on an upgraded 3-nanometer process. It features a 6-core CPU with two performance cores and four efficiency cores. There's a 5-core GPU, offering performance and efficiency improvements over the A18.There's an updated display engine, image signal processor, and 16-core Apple Neural Engine. Each GPU core includes a Neural Accelerator that boosts daily workflows and the performance of local AI models, like on-deviceSiri.Hardware-accelerated ray tracing enables console-quality gaming with improved frame rates and visual effects. The A19's efficiency improvements bring a significant battery life boost.The iPhone 17 includes 8GB of RAM, which is the minimum for Apple Intelligence and the same amount of RAM in the iPhone 16. The other iPhone 17 models feature 12GB RAM.

Storage Space

The iPhone 17 starts with 256GB of storage, double the starting storage of the iPhone 16. There is also a 512GB upgrade option for

Dual-lens rear cemra 

There continues to be a dual-lens rear camera system in the iPhone 17 with a Wide lens and an Ultra Wide lens. The main wide-angle lens, which Apple calls a Dual Fusion camera, is essentially the same as the wide-angle lens in the iPhone 16, but the Ultra Wide lens hasbeenupgradedfrom12megapixels to 48 megapixels.

TheFusion lens are used for the 2× "telephoto" imagesUltra Wide images are24megapixels by default, which Apple says is the ideal size for high-quality storing and sharing. At 24 megapixels, every two pixels are combined into onepixel,allowingforhigher-resolution images that have more detail and better low-light performance. The Ultra Wide lens also supports macro shots

Dual Capture

Dual Capture is a video recording feature that records with the front and rear-facing cameras at the same time, for reaction-style videos. Dual Capture supports 4K Dolby Vision at up to 30 frames per second.

Video Capabilities

The iPhone 17 models support up to 4K video recording at 24, 25, 30, or 60 frames per second. HDR recording, ProRes video, Cinematic mode, Action mode, slo-mo video, and time-lapse are all supported.

QuickTake mode, which allows you to capture video by holding down the camera button, now supports 4K at 60 fps in Dolby Vision.Spatial Audio sound recording is available for dynamic, immersive sound for videos, and wind noise reduction cuts down on wind sound when recording.

AudioMax

Audio Mix is a video feature that takes advantage of Spatial Audio capture. You can use it to adjust the way that voices sound in videos, and there are three different options.

• In-frame - Only captures the voices of people on camera, even if people off camera are talking.
• Studio - Makes voices sound like the recording was done in a professional studio with sound-dampening walls. A recording sounds like the mic was close to the subject's mouth.
• Cinematic - Captures all voices and consolidates them to the front of the screen, which is how sound is formatted formovies.

Other Camera Features

There are several other camera bells and whistles that Apple has been adding to the iPhones over the years.

• Portrait Features - You don't need to choose Portrait mode before capturing an image to get a portrait shot. You can just snap a photo, and if there's a person or a pet, depth information is collected and Portrait mode is enabled automatically with a blurred background. This year, the feature works for Night mode shots and it supports Portrait Lighting.

• Smart HDR 5 - Recognizes one or more people in a scene and optimizes contrast, lighting, and even skin tones for each person so everyone looks their best.

• Photographic Styles - Photographic Styles are tints that you can apply to an image before or after it's taken. You can use a live preview feature, and intensity of color and tone can be adjusted. There's a new Bright style this year.

• Photonic Engine - The Photonic Engine combines the best pixels from a high-resolution image and an image optimized for light capture, leading to a 24-megapixel image with detail drawn from an image twice the resolution.

• Night mode - Takes a series of images over a few seconds and aggregates them to allow for photography in extreme low lighting situations.

• Deep Fusion - Works in mid to low lighting conditions and brings out the texture and detail in the image.

• Portrait Lighting - Changes the lighting of Portrait mode photos with effects that include Natural, Studio, Contour, Stage, Stage Mono, and High-Key Mono.

• True Tone flash - True Tone flash is the built-in flash, and it is designed to match the ambient lighting so it doesn't throw off the white balance of the photo when used.

• Cinematic mode - A video mode that keeps the focus on the main subject that you're filming even as you move.

• Action mode - Enhances image stabilization to improve shaky handheld video.

• Panorama - Captures panoramic shots up to 63 megapixels.

• Burst mode - Allows a series of images to be captured all at once, which is good for high-action shot.

The iPhone 17 can charge faster than the iPhone 16. It is able to reach a 50 percent charge in 20 minutes using a 40W or higher power adapter. It can charge up to 50 percent in 30 minutes over MagSafe when using a 30W or higher power adapter.Apple added support for Qi2.2, so the iPhone 17 is able to charge at up to 25W using compatible Qi2.2 chargers. Qi2.2 offers the same charging speeds as MagSafe, which also maxes out at 25W.

5G Connectivity

The iPhone 17 uses a Snapdragon X80 modem from Qualcomm. The X80 features AI accelerator hardware that intelligently enhances cellular data speeds, latency, coverage, and power efficiency.etworks are the fastest 5G networks, but mmWave is short-range and can be obscured by buildings, trees, and other obstacles, so its use is limited to major cities and urban areas along with venues like stadiums, airports, and other places where a lot of people congregate.Sub-6GHz 5G is more widespread and available in urban, suburban, and rural areas across the United States and other countries. For the most part, when you use a 5G network, you'll be using sub-6GHz 5G. Sub-6GHz 5G is faster than LTE, especially when mid-band spectrum is used, but it isn't always the blazing fast 5G that you expect.

5G Bands

• Sub-6GHz 5G - High band FDD-5G NR (n1, n2, n3, n5, n7, n8, n12, n14, n20, n25, n26, n28, n29, n30, n66, n70, n71, n75, n76) and low band TDD-5G NR (n38, n40, n41, n48, n53, n77, n78, n79)
• mmWave 5G - n258, n260, n261

• TDD-LTE - Bands 34, 38, 39, 40, 41, 42, 48,

Emergency SOS via Satellite

The iPhone 17 can connect to satellites in emergency situations when cellular and Wi-Fi connections are not available. Apple has designed the Emergency SOS via satellite feature to allow the iPhone's antennas to connect to satellites operated by Globalstar.

Satellite communications are available in emergency situations where you can't connect to Wi-Fi or a cellular tower, and the feature is designed to be used in open spaces with few trees so the iPhone can connect to a satellite that's in the sky.Apple has a walkthrough interface that instructs you how to hold the iPhone to connect to a satellite, and the company has developed a compressed messaging protocol because sending data via satellite can take minutes. In an area with no trees, a short message to emergency services can send in as little as 15 seconds.Emergency SOS via satellite provides a series of important questions that you answer when it is activated, with these questions aimed at getting necessary details to emergency personnel as quickly as possible. The answers that you provide are sent directly to emergency services if text communication is supported in your area, or sent to relay centers staffed by Apple-trained specialists who can call emergency services on the user's behalf.Satellite connectivity is mainly designed to allow users to contact emergency services in dire situations, but it can also be used to update your Find My location if you're camping or hiking off the grid, giving your family and friends peace of mind about where you are.Emergency SOS via satellite is free for all iPhone 17 users for two years, and Apple has not yet provided details on what it will cost in the future.The iPhone 17 models also support Messages via satellite, Find My via satellite, and Roadside Assistance via satellite, which allows iPhone users to contact local service providers for help if they have car trouble in an area without cellular or Wi-Fi connectivity. There is no charge for the satellite usage with Roadside Assistance, though there may be a fee charged by the roadside service provider.

Crash Detection

There's a high dynamic range gyroscope and a dual-core accelerometer capable of detecting G-force measurements of up to 256Gs in the iPhone 17 models, and paired with other iPhone sensors like a barometer that can detect cabin pressure changes caused by deployed airbags, this hardware enables a Crash Detection feature.

The iPhone 17 can detect a severe car crash and automatically dial emergency services when the car's occupants are seriously injured or unable to reach their phones. The GPS in the iPhone is able to detect speed changes, and the microphone is able to recognize loud sounds associated with severe car crashes. Crash Detection is also available on the Apple Watch, and the iPhone and Apple Watch work together to contact emergency services when an accident occurs.
