Unlocked 5G smartphone with 512GB storage

The Galaxy S25 Ultra is an unlocked GSM handset with 12GB RAM and 512GB internal storage. It runs Android 15 with One UI 7 and is powered by the Snapdragon 8 Elite chipset. Dual SIM support lets you manage two numbers on one device.

AI camera system and mDNIe display optimisation

A quad-camera array combines a 200MP main sensor with 50MP, 50MP and 10MP modules for 3x and 5x optical zoom plus 2x and 10x optical-quality zoom. Galaxy AI enhances colour and detail through the Super Vision Engine. The mDNIe display technology optimises applications to extend battery life during video playback.

Buyers needing expandable storage

The handset offers no microSD slot, so the 512GB capacity cannot be increased after purchase. The main display measures 6.9 inches with a 92.5% screen-to-body ratio, which may not suit users who prefer a more compact form factor.

Questions about this item

Will the 512 GB storage ever need to be expanded or replaced?

The 512 GB internal storage is fixed and cannot be upgraded; if you fill it you must offload files to cloud or a computer rather than add a larger module.

What limits the Snapdragon 8 Elite during prolonged heavy workloads?

Sustained performance is capped by the phone’s thermal envelope; the chip throttles once the titanium frame and vapour chamber can no longer dissipate heat fast enough.

How loud or hot does the 6.9 inch display area get when the phone runs all day?

The display itself stays silent; the rear chassis near the camera module becomes noticeably warm during continuous 4K recording or gaming, but surface temperatures remain within normal operating limits.
