Apple iPhone 17 / Samsung Galaxy Z Flip6

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.

The vapor chamber spreads heat from the chip over a wider area to delay throttling in long gaming and recording sessions; it is a first for the Z Flip line.

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; Samsung does 2x zoom by cropping the 50 MP sensor and up to 10x with AI-assisted digital zoom.

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.

With the phone closed the rear cameras can also take selfies, using the cover screen as a viewfinder.

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 rated capacity is 3,887 mAh. The 25 W adapter is sold separately. Wireless PowerShare lets the back of the phone charge Qi-compatible devices such as earbuds and watches.

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.

Counting the rounded corners the screen is 6.6 inches. A light crease can be visible at the fold; Samsung says new screen layers reduce it.

Notifications, widgets, music controls and suggested replies work without opening the phone; the actual viewable area is about 95% because of the corners and the lower cutout.

There is no memory card slot; storage cannot be expanded later.

The 4 in IP48 only protects against solid objects larger than 1 mm; it does not mean dust-tight. Samsung does not advise beach or pool use.

The 6 GHz band of Wi-Fi 6E needs a compatible router and is not open in every country.
