Apple iPhone 17 / Samsung Galaxy S25+

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.

The refresh rate drops as low as 1 Hz depending on content to save power. Vision Booster adjusts tones in bright light. Accounting for rounded corners the visible area is 6.5 inches.

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.

The 3x telephoto keeps more detail than a digital crop for close portraits and distant subjects.

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.

Wireless PowerShare lets the back of the phone wirelessly charge accessories such as earbuds or a watch. The 45W adapter may be sold separately.

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.

All models in the series use the same chip, a Snapdragon 8 Elite version tuned to higher clocks for Galaxy.

Samsung says the frame contains at least 20% recycled aluminium by weight.

Wi-Fi 7 brings higher speeds and lower latency only with a compatible router.

Dust-tight and resistant to fresh water for a set depth and time; it is not a guarantee for sea water or pool chemicals.
