vivo X500 / Samsung Galaxy S23 Ultra

Model code listed for China; the manufacturer document gives no other regional code.

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

This record covers the 12 GB model. Usable memory is lower than the label because the system reserves a share.

Usable space is lower than the label because of the system and preinstalled apps.

vivo says 144 Hz applies in gaming scenarios.

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.

Peak values, not sustained brightness.

The manufacturer does not name the front glass.

The 200 mm-equivalent teleconverter is sold separately and is not in the box.

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

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

90 W is the charger's maximum output; actual power varies with conditions. The wireless charger is sold separately.

The document gives no power figure.

The hardware supports 6.0; some functions will arrive in a later OTA update.

The headset connection takes digital USB-C headsets only.

NFC-SIM payments work only from the SIM 1 slot.

5G dual-SIM works only with some band combinations and with operator SA/VoNR support.

Actual availability depends on the carrier network and software version.

The 15% larger VC area versus the previous generation is vivo's own claim.

vivo states this is not a professional waterproof phone and that immersion damage is not covered by warranty.

Names in brackets are translations; the vivo China page names the colours in Chinese.

The document gives no update commitment.

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

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.

Samsung does not recommend beach or pool use.
