Since acquiring the retail unit, Karoul has been meticulously testing various features. Early reports suggest the device might include a 24-month warranty in specific regions. While there is some disappointment regarding the S Pen lacking Bluetooth functionality, the new "Privacy Display" feature has impressed testers. However, the most significant revelation lies in the raw performance benchmarks which position the **Snapdragon 8 Elite** as a mobile powerhouse.

Performance Breakdown: Snapdragon 8 Elite Gen 5 Power

The Galaxy S26 Ultra unit tested features Qualcomm's latest flagship silicon, the Snapdragon 8 Elite Gen 5. In the AnTuTu benchmark, which measures overall system performance, the device reached a staggering score of 3,720,219 points. For context, this represents a monumental increase over previous generations, ensuring that multitasking, AI processing, and high-end gaming remain fluid.

CPU performance also saw a healthy boost. In Geekbench 6, the device achieved 3,648 points in single-core testing and 10,898 points in multi-core testing. These numbers suggest that the S26 Ultra will handle intensive applications and heavy workloads with ease, outperforming almost every other smartphone currently on the market.

Stability and Thermal Efficiency

One of the most critical improvements in the Galaxy S26 Ultra is how it manages heat. In the 3DMark Wild Life Extreme Stress test, the phone recorded a high score of 6,489 and a low of 3,455, maintaining a stability rating of 53.2%. While the stability percentage might seem modest, the thermal data is what truly stands out. During this intense test, the internal temperature rose by only 10 degrees Celsius (from 34°C to 44°C).

Testers noted that the phone did not feel uncomfortably hot to the touch during these benchmarks. This is a significant step forward in mobile engineering, as it allows the processor to maintain higher speeds for longer periods without aggressive throttling.
