What the Galaxy S25 Ultra delivers

The Samsung Galaxy S25 Ultra S938B is an unlocked AI smartphone built for photographers and power users who want maximum camera versatility and long battery life in a single device. It ships with 12GB of RAM and 256GB of storage, running Android 15 with One UI 7. The titanium frame and 6.1-inch display keep the design modern and minimalist.

Thermals noise and power draw

The upgraded Snapdragon 8 Elite chip includes mDNIe display optimisation that reduces power consumption during video playback, extending daily runtime. Android 15 is supported with up to 7 major upgrades, keeping background processes efficient over time. The large vapour-chamber cooling area handles sustained workloads without audible fan noise because the phone has no moving parts.

Build fit and what it frees up

Dual SIM support lets you combine personal and work lines without carrying a second handset. The 200MP main sensor plus 3x and 5x optical zooms replace a dedicated compact camera for most travel shots. 12GB RAM keeps multi-window multitasking smooth, while 256GB internal storage removes the need for a microSD card in everyday use.

Questions about this item

How do I insert the dual nano-SIM cards into the Galaxy S25 Ultra S938B tray?

Power off the phone, push the SIM-eject tool into the small hole on the bottom edge, pull the tray out, place both nano-SIMs in the marked slots with gold contacts down, then slide the tray back until it clicks.

What battery-related service will this phone need after a couple of years?

The built-in cell is not user-replaceable; when runtime drops noticeably you will need an authorised service centre to swap the battery and reseal the water-resistant adhesive.

Which hardware limit appears first during long 8K video recording sessions?

Thermal throttling from the Snapdragon 8 Elite chipset kicks in before storage fills, reducing frame rates and brightness until the titanium frame dissipates enough heat.
