OnePlus 13 vs Samsung Galaxy S25 Ultra
Side-by-side specifications, scores and verdict.
Quick Verdict
OnePlus 13 delivers superior value at $400 less, featuring a larger 6.82-inch display with exceptional 4500-nit peak brightness and smoother 120Hz LTPO refresh. Its 6000mAh battery with 100W charging significantly outlasts Galaxy S25 Ultra's 5000mAh pack and glacial 45W speeds. Camera systems differ strategically: OnePlus excels with versatile 50MP telephoto and ultrawide sensors plus 8K video at 30fps, while Samsung prioritizes megapixels with a 200MP main sensor and dual telephoto setup including impressive 5x periscope zoom. Both share Snapdragon 8 Elite chips and 12GB RAM, ensuring comparable performance. Samsung's titanium frame and Gorilla Glass Armor 2 offer premium materials, though OnePlus maintains respectable durability with aluminum and Glass 7i. For most users, OnePlus 13 represents exceptional flagship performance without the premium markup, making it the smarter choice unless you specifically need Samsung's software ecosystem or extreme zoom capabilities.
