Apple iPhone 17 / Apple iPhone 13

ProMotion adjusts the refresh rate to the content: 120 Hz smoothness when scrolling, lower rates on still images to save battery. The Always-On display shows the time and notifications dimmed while locked. Because of the rounded corners, the visible area is slightly smaller than the rectangle measurement.

Typical maximum brightness is 800 nits, with 1200 nits peak for HDR content; typical contrast is 2,000,000:1. The spec page does not list a refresh rate; the Pro models’ ProMotion is not on this model. Because of the rounded corners, the visible area is slightly smaller than a 6.06-inch rectangle.

3,000 nits is a short peak in strong sunlight, not sustained full-screen brightness. The 1-nit minimum aims to avoid eye strain in a dark room. The screen has anti-reflective and oleophobic coatings.

According to Apple, the colour-infused back glass is used on Black, Mist Blue, Sage and Lavender.

Apple notes that this resistance is not permanent, may decline with normal wear, and that liquid damage is not covered by the warranty.

The GPU supports hardware-accelerated ray tracing; the Neural Accelerators speed up AI work inside the GPU.

The iPhone 13 Pro and iPhone 14 use a five-core-GPU version of the same chip; on this model the GPU has four cores.

There is no memory card slot.

Capacity is chosen at purchase; there is no memory card slot.

The 2× image comes from the centre of the 48 MP main sensor rather than a separate telephoto lens; the optical-quality zoom range is 4× in total, with digital zoom up to 10×. The ultra wide camera also takes 48 MP macro photos.

There is no telephoto camera: 2x refers to switching from the main to the ultra wide camera. Sensor-shift stabilisation compensates for hand shake by moving the sensor rather than the lens. Night mode, Deep Fusion, Smart HDR 4 and Photographic Styles are available.

Dual Capture records with the front and rear cameras at the same time. Action mode strongly stabilises footage shot while walking or running.

Cinematic mode blurs the background and can shift focus between people automatically; on this model it is limited to 1080p at 30 fps. Recording formats are HEVC and H.264; 8 MP stills can be taken while recording 4K.

Center Stage automatically adjusts the framing to the people in photos and video calls; the TrueDepth system for Face ID works with this camera.

25 W wireless charging needs a 30 W or higher adapter; no adapter is included. Battery life varies with Apple’s test conditions, network and settings.

The fast-charge figure comes from Apple’s testing with a 20 W USB-C adapter, sold separately. MagSafe aligns chargers and accessories with a magnet array on the back.

Wired data transfer is limited to USB 2 speed, so moving large video files takes time. USB-C can output to an external display at up to 4K HDR.

Thread provides low-power mesh connectivity with smart-home devices. Ultra Wideband helps locate devices such as AirTag by direction and distance; availability varies by country.

Emergency SOS and Roadside Assistance via satellite are offered depending on country; Crash Detection is included.

The Action button can be set to functions such as silent mode, torch, translate or a shortcut. Camera Control is a touch-sensitive button that adjusts exposure, depth and zoom by sliding.

No power adapter or EarPods are included.

The front camera also records 4K Dolby Vision video and Cinematic mode.

The band list depends on the model number: the UK model A2633 lists no mmWave bands; the US model A2482 supports n258/n260/n261.

Using eSIM requires carrier support and it is not supported in every region.

Adapters are sold separately.
