Apple iPhone 17 / Samsung Galaxy Z Fold5

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.

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.

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.

30x Space Zoom adds digital zoom on top of the 3x optical zoom; image quality may drop beyond 3x.

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

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.

Rated capacity is 4,270 mAh. The 25 W adapter is sold separately. Wireless PowerShare lets the back of the phone charge Qi-compatible watches, earbuds or phones.

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.

Adaptive refresh rises to 120 Hz for motion and drops to 1 Hz for still images to save battery. Allowing for the rounded corners the screen is 7.4 inches; the fold line can be visible in use.

The 23.1:9 ratio makes the cover screen tall and narrow; it works like a regular phone screen when closed.

There is no memory card slot; options vary by market.

The under-display camera leaves no hole in the inner screen, but shooting through the pixels lowers image quality.

The “X” means dust protection is not rated; Samsung does not advise beach or pool use.

The SIM and eSIM arrangement varies by market and carrier.
