Apple iPhone 17 / Samsung Galaxy S23+ (SM-S916B)

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 varies between 48 and 120 Hz depending on content; the lower rate on static screens saves battery. Vision Booster adjusts contrast and colour to keep the screen readable in bright light. The size is measured as a full rectangle; the viewable area is smaller because of the rounded corners and camera hole.

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 telephoto gives 3x optical zoom; zoom beyond that is digital. According to Samsung the wide camera records 8K video at 30 fps.

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.

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.

According to Samsung, the S23 series was the first S series to use Victus 2.

Samsung introduced this version as a Snapdragon optimised for Galaxy and exclusive to the S23 series at launch.

Available storage is lower because of preloaded software; there is no memory card slot.

The typical value is the average of battery samples measured by a third-party lab under IEC 61960; the rated value is the minimum capacity.

45 W needs a 5 A cable; the adapter is sold separately. Wired charging is compatible with QC2.0 and AFC, wireless with WPC. PowerShare needs more than 30% battery to charge another device. The S23 is limited to 25 W.

Samsung promised four Android upgrades and five years of security updates for the S23 series; timing varies by model and market.

Wi‑Fi 6E needs a router that supports 6 GHz; band availability varies by market and operator.

Samsung does not advise beach or pool use.
