## What reviewers say

**Samsung Galaxy S25 Ultra** — Two whitelisted lab testers (Tom's Guide, GSMArena) reviewed the exact Galaxy S25 Ultra. Both praise the overclocked Snapdragon 8 Elite speed, and Tom's Guide measured strong battery endurance (17h14m). Display measurements diverge by methodology. Both flag the slow 45W charging (~59 min to full); GSMArena calls the panel solid but not cutting-edge, while Tom's Guide rates the display excellent and brighter than the iPhone 16 Pro Max. (2 sourced reviews.)
