Samsung Galaxy Z Fold7 / Apple iPhone 17

The adaptive refresh rate rises to 120 Hz when scrolling and drops as low as 1 Hz on static content to save battery. The foldable inner screen has a plastic protective layer and is not as hard as glass.

The 21:9 ratio gives a width close to an ordinary phone for typing while folded.

The peak is reached briefly in strong light; it is not a sustained full-screen value.

Samsung says Advanced Armor Aluminum gives a 10% gain in strength and hardness over the previous frame.

The 4 in IP48 refers to protection against solid objects larger than 1 mm; it is not a rating against fine dust. Samsung’s water test was done in fresh water.

16 GB of memory comes only with the 1 TB version; there is no memory card slot.

3× optical zoom uses the telephoto lens; 30× Space Zoom adds AI-assisted 10× digital zoom on top of the 3× optical.

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.

The dual battery consists of cells split across both halves. Wireless PowerShare provides wireless power from the back of the phone to accessories such as earbuds or a watch.

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 SIM layout varies by market and carrier.

Knox Vault keeps sensitive data such as passwords and biometrics in a separate secure processor and memory.

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.

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.

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.
