Samsung Galaxy S25 Ultra 256GB

The Samsung Galaxy S25 Ultra SM-S938U1 is a flagship smartphone with 256GB storage and 12GB RAM. It runs Android 15 on a Qualcomm SM8750-AB octa-core processor. The 6.9-inch Dynamic AMOLED 2X display delivers QHD+ 3120 x 1440 resolution. This unlocked device suits users wanting premium hardware without a carrier contract.

Sustained performance and thermal behaviour

The octa-core CPU combines two 4.47 GHz cores with six 3.50 GHz cores for multi-threaded workloads. Under continuous load the titanium frame helps dissipate heat across the chassis. IP68 water and dust resistance maintains sealing during extended use. The 12GB RAM supports background processes without aggressive app termination.

Installation experience and common issues

As a sealed bar handset there is no internal hardware installation required. Users insert a nano-SIM and configure Android 15 during first boot. Data transfer from an old phone uses Samsung Smart Switch over cable or wireless. The main friction point is migrating proprietary app logins and two-factor authentication tokens manually.

Questions about this item

How much heat or battery drain does the 4.47 GHz dual-core plus 3.50 GHz hexa-core processor create during all-day use?

The octa-core Qualcomm SM8750-AB runs two high-performance cores at 4.47 GHz and six efficiency cores at 3.50 GHz, so demanding tasks use the faster cores while background work stays on the efficient cluster, keeping thermals and power draw balanced through a full day.

What existing SIM or eSIM plan do I need to activate this no-contract unit?

The phone is sold without a contract and supports 5G, so you only need an active nano-SIM or compatible eSIM profile from any carrier that allows bring-your-own-device activation on their 5G network.

Will my older USB-A chargers and cables still charge the 256 GB model at full speed?

The device uses USB-C for charging and data; legacy USB-A chargers will work but only at their rated output, while the included USB-C cable and a USB-PD PPS charger are required for the handset's maximum wired charging rate.
