Samsung Galaxy S25 Ultra review

On paper, the S25 Ultra is built around a bright 6.8" QHD+ LTPO AMOLED (2600 nits peak), a 200MP-led quad camera with 3x and 5x optical zoom, Snapdragon 8 Gen 4 (3 nm), and Android 15 with up to 7 major upgrades. The tradeoffs are predictable for an Ultra: large/heavy (219 g), no headphone jack, no microSD, and FCC SAR values that rise notably during simultaneous transmission/hotspot use.

SAR and RF snapshot

• Head SAR (cellular): 1.26 W/kg
• Body SAR (cellular): 0.78 W/kg
• Head SAR (Wi‑Fi + cellular / simultaneous): 1.59 W/kg
• Body SAR (Wi‑Fi + cellular / simultaneous): 1.40 W/kg
• Hotspot SAR (simultaneous): 1.48 W/kg
• FCC ID: A3LSMS938B
• How to read this: Head and body SAR reflect certified testing for cellular use. Simultaneous SAR is the more relevant value when cellular and other radios such as Wi‑Fi are active together. Lower exposure in day-to-day use usually comes from distance, shorter high-power sessions, weak-signal avoidance, and turning unused radios off.
