vivo X500 / Samsung Galaxy S25 Ultra

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

Samsung quotes 40% NPU, 37% CPU and 30% GPU gains over the previous generation. This version is tuned for Galaxy with higher clocks than the standard Snapdragon 8 Elite.

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.

The viewable area is smaller than the diagonal because of rounded corners and the camera hole. Refresh that drops to 1 Hz saves power on static content; Vision Booster adjusts tone mapping in bright light.

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.

Log records a flat profile for colour grading; results depend on the editing workflow. Audio Eraser can reduce layers such as voices, music, wind and crowd separately in videos.

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.

The vapor chamber spreads heat from the chip into the body, helping clocks hold longer in extended gaming.

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

Water resistance is not permanent and may diminish over time.

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

Colour availability varies by country and carrier.

The document gives no update commitment.

According to Android Central’s one-year report, the phone received One UI 8 (Android 16) ahead of schedule.

The Samsung Newsroom release is dated 23 January Korea time; the event was 22 January in US time.

Samsung notes memory options may vary by market and usable storage is lower because of preloaded software. There is no card slot.

Used on the front only. Corning says it survived drops of up to 2.2 m onto a concrete-like surface in internal lab tests; this is not a durability guarantee for any given phone.

Titanium is used only on the frame, excluding the volume and side keys.

Per Samsung, 3× and 5× are optical; 2× and 10× are “optical quality” zoom made by sensor cropping. OIS is optical image stabilisation.

The 45 W adapter is sold separately. Samsung quotes up to 31 hours of video playback. Wireless PowerShare charges earbuds or a watch from the back of the phone.

5G/LTE availability depends on market and carrier.
