Samsung Galaxy S25 Ultra / Apple iPhone 12

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.

The display is 60 Hz; Apple does not list ProMotion for this model. Because of the rounded corners the rectangle measures 6.06 inches and the actual viewable area is slightly less. True Tone adjusts white balance to ambient 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.

There is no telephoto camera; 2x optical zoom out means switching to the ultrawide. Night mode and Deep Fusion merge several frames in low light to reduce noise. Smart HDR 3 and Portrait mode with six Portrait Lighting effects are supported.

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.

Dolby Vision recording is limited to 30 fps at 4K; 4K at 60 fps does not use Dolby Vision HDR. 8 MP stills can be taken while recording 4K.

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 power adapter is included; the box contains only a USB-C to Lightning cable and documentation. MagSafe uses a magnet array on the back to align chargers and accessories.

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.

1,200 nits applies only to HDR video and photos; the normal interface tops out at 625 nits. The 2,000-nit outdoor mode of newer iPhones is not on this model.

The Neural Engine speeds up photo processing such as Deep Fusion and Night mode and other on-device machine-learning tasks.

There is no memory card slot; formatted capacity is lower.

The UK page lists model A2403; bands depend on the model number and this page has no mmWave. Express Cards with Power Reserve keep some transit cards usable for a few hours after the battery runs out.

It is not USB-C. Wired video out through the Lightning Digital AV Adapter is limited to 1080p; AirPlay to Apple TV mirrors up to 4K HDR.

eSIM use depends on carrier support.

Apple says a very small percentage of devices may have a failing component in the receiver module, so no sound is heard on calls. The programme covered units for 3 years after first retail sale and does not extend the warranty; other damage such as a cracked screen may need fixing first. The iPhone 12 mini and 12 Pro Max are not included.
