Samsung Galaxy S25 Ultra / Apple iPhone 15 Pro

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.

On OLED each pixel emits its own light, so blacks turn fully off; typical contrast is listed as 2,000,000:1.

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.

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.

ProRes 4K at 60 fps requires recording to external storage over USB-C. Log records a flat profile for colour grading.

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.

No adapter is included. Qi2 is a wireless charging standard with magnetic alignment like MagSafe.

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.

mmWave support varies by region. Thread is for low-power networking with smart home devices.

Water resistance is not permanent and may diminish over time.

Colour availability varies by country and carrier.

The panel rises to 120 Hz when scrolling and gaming and drops its rate for static content to save power, which lets the lock screen stay on.

The outdoor figure is used only briefly in strong sunlight; normal use sits around 1000 nits.

Sensor-shift stabilisation moves the sensor rather than the lens to counter hand shake; the default capture is 24 MP.

The 2× image is taken from the centre of the 48 MP sensor; the 15× digital zoom is not optical.

10 Gb/s needs a USB 3 cable; the 1 m cable in the box is a charge cable and does not guarantee that speed.

Receiving satellite signals on two frequencies helps reduce position drift between tall buildings.

It replaces the old mute switch; pressing and holding runs the chosen function.
