Apple iPhone 17 Pro Max / Samsung Galaxy S23 Ultra

ProMotion adjusts the refresh rate to the content, giving 120 Hz smoothness when scrolling and lowering it on still images to save battery. The Always-On display shows the time and notifications dimmed while locked.

Adaptive refresh drops to as low as 1 Hz when content is static to save power and rises to 120 Hz when scrolling and gaming. Vision Booster adjusts colour and contrast in bright conditions across three lighting levels; the edge curve is reduced compared with the S22 Ultra.

The 3,000-nit outdoor figure is a short peak in strong sunlight, not sustained full-screen white. The screen has an anti-reflective coating.

Apple notes that this resistance is not permanent and can decrease with normal wear.

Samsung does not recommend beach or pool use.

The GPU supports hardware-accelerated ray tracing.

It also gives a 12 MP 2× (48 mm) image by using the centre of the sensor.

This camera is also used for 48 MP macro shots.

Using the centre of the sensor gives a 12 MP 8× (200 mm) image; Apple quotes a 16× optical-quality range and up to 40× digital zoom.

4K 100/120 fps is limited to the main camera. ProRes 4K 120 fps requires recording to external storage. Genlock syncs several cameras to the same timing with compatible hardware.

The Expert RAW app (downloaded separately from the Galaxy Store) offers RAW capture at up to 50 MP.

The Center Stage camera’s square sensor allows landscape or portrait selfies without rotating the phone.

On the S23 series the front camera gets fast autofocus and 60 fps Super HDR.

No adapter in the box; only a 1 m USB-C charge cable.

Apple quotes about 50% in 30 minutes with a 30 W or higher adapter and MagSafe Charger.

10 Gb/s needs a compatible USB 3 cable; the included cable does not guarantee that speed.

Ultra Wideband availability varies by region.

Availability of satellite features varies by country.

Camera Control opens the camera and changes settings such as zoom and exposure with slide and light-press gestures.

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

Samsung says the vapour chamber is larger on every S23-series model.

Memory depends on the storage option; usable space is lower because of preloaded software. There is no memory card slot.

The 200 MP sensor outputs 200, 50 or 12 MP images through pixel binning. 100x Space Zoom combines 10x optical with 10x AI-assisted digital zoom; image quality may deteriorate beyond 10x. The optical stabilisation angle was doubled compared with the S22 Ultra.

45 W requires a separately sold 45 W adapter and a 5 A USB-C cable; wired charging is compatible with QC2.0 and AFC. Wireless PowerShare charges Qi-compatible devices from the back of the phone when the battery is above 30%.

Update timing can vary by model and market.

Using Wi‑Fi 6E’s 6 GHz band needs a Wi‑Fi 6E router and market availability.

Knox Vault keeps critical data in separate hardware isolated from the operating system.
