Verdict: Choose the Samsung Galaxy S26 Ultra first if you want the fastest charging speeds, an integrated hardware Privacy Display, and the latest Snapdragon 8 Elite Gen 5 processing power.

Choose the Samsung Galaxy S26 Ultra for its hardware Privacy Display, faster 60W charging, and Snapdragon 8 Elite Gen 5 chipset, or opt for the Samsung Galaxy S25 Ultra if 45W charging and Snapdragon 8 Elite performance already meet your needs.

The Samsung Galaxy S26 Ultra outperforms the Samsung Galaxy S25 Ultra across all evaluated metrics, highlighted by an upgrade from 45W to 60W wired fast charging on an identical 5,000 mAh battery capacity. Both devices feature 6.9-inch displays, but the Samsung Galaxy S26 Ultra introduces a hardware-level Privacy Display over the standard Dynamic LTPO AMOLED 2X panel on the Samsung Galaxy S25 Ultra. Performance is pushed forward via the 2026 Snapdragon 8 Elite Gen 5 processor compared to the 2025 3nm Snapdragon 8 Elite for Galaxy chip, while the 200MP quad-camera array gains next-generation AI sensor pipeline refinements. Furthermore, launching out of the box with Android 16 and One UI 8.5 extends the Samsung Galaxy S26 Ultra's 7-year support window a full year beyond the Android 15 launch baseline of the Samsung Galaxy S25 Ultra.
