Samsung Galaxy S25 Ultra / Samsung Galaxy Z Fold6

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.

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.

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

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.

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.

Zoom beyond 3× is digital; detail drops as zoom increases.

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.

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.

Usage times are Samsung lab figures (NZ page); real-world time depends on screen use.

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

5G/LTE availability depends on market and carrier.

Water resistance is not permanent and may diminish over time.

Colour availability varies by country and carrier.

Colour options can vary by country; this list is from Samsung New Zealand’s page.

The folding inner screen has a crease along the hinge line in the middle; this comes from how foldable displays are built.

The outer screen is narrow and tall; with the phone closed it is used like a regular smartphone.

The peak figure is the manufacturer’s maximum for a small part of the screen over a short time.

The under-display camera keeps the inner screen uninterrupted; its resolution is lower than the cover camera’s.

The 4 in IP48 means protection against solids larger than 1 mm; there is no protection against fine dust.

This is the version the phone launched with, not the current version.
