Apple iPhone 16 / Samsung Galaxy S23+ (SM-S916B)

Apple says the A18, built on second-generation 3 nm technology, is up to 30% faster in CPU and 40% in GPU than the A16 Bionic and supports hardware ray tracing. The A18 Pro in iPhone 16 Pro is a different chip.

Typical brightness is 1000 nits, 1600 nits HDR and 2000 nits peak outdoors, with a 1-nit minimum. 2,000,000:1 contrast, P3 wide colour and True Tone. Apple does not list a refresh rate; ProMotion and always-on display are on the Pro models.

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.

Apple says it is 50% tougher than the first-generation Ceramic Shield. The back is colour-infused glass and the frame is aluminium.

The 2× view comes from the centre of the 48 MP sensor rather than a separate lens. There is a 4× optical zoom range and up to 10× digital zoom; the ultra-wide camera can shoot macro.

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

Apple says Camera Control combines a tactile switch for clicks, a force sensor for light presses and a capacitive sensor for swipes. It opens the camera, takes photos and starts video recording.

Ultra Wideband availability varies by region. Emergency SOS and Roadside Assistance via satellite are supported, with service duration and country coverage set by Apple.

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

SIM layout may vary by country model.

Wired data transfer is limited to USB 2 speed, so moving large video files by cable is slower than on the Pro models.

Reaching 50% in 30 minutes over MagSafe needs a 30 W or higher adapter. There is no adapter in the box, only a USB-C cable.

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.

Measured under Apple’s test conditions; real results vary with use and settings. Apple does not publish the capacity in mAh.

Splash, water and dust resistance is not permanent and may decrease over time; liquid damage is not covered by warranty.

The high-g accelerometer is used for Crash Detection.

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.

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

Samsung does not advise beach or pool use.
