Samsung Galaxy Z Fold7 / Samsung Galaxy S23+ (SM-S916B)

The adaptive refresh rate rises to 120 Hz when scrolling and drops as low as 1 Hz on static content to save battery. The foldable inner screen has a plastic protective layer and is not as hard as glass.

The 21:9 ratio gives a width close to an ordinary phone for typing while folded.

The peak is reached briefly in strong light; it is not a sustained full-screen value.

Samsung says Advanced Armor Aluminum gives a 10% gain in strength and hardness over the previous frame.

The 4 in IP48 refers to protection against solid objects larger than 1 mm; it is not a rating against fine dust. Samsung’s water test was done in fresh water.

Samsung does not advise beach or pool use.

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

16 GB of memory comes only with the 1 TB version; there is no memory card slot.

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

3× optical zoom uses the telephoto lens; 30× Space Zoom adds AI-assisted 10× digital zoom on top of the 3× optical.

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

The dual battery consists of cells split across both halves. Wireless PowerShare provides wireless power from the back of the phone to accessories such as earbuds or a watch.

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

The SIM layout varies by market and carrier.

Knox Vault keeps sensitive data such as passwords and biometrics in a separate secure processor and memory.

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.

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

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.
