OnePlus 13R vs Samsung Galaxy S25 Ultra

OnePlus 13R

The 6.78-inch LTPO AMOLED display delivers 120Hz, 2780x1264 resolution, and 4,500 nits peak brightness — one of the best screens at this price.

• LTPO AMOLED panel delivers sharp, vibrant visuals with excellent color reproduction across sRGB and DCI-P3 gamuts
• Real-world auto brightness of around 1,223 nits provides comfortable outdoor visibility in direct sunlight

Samsung Galaxy S25 Ultra

The 6.9-inch Dynamic AMOLED 2X display with 2600 nit peak brightness and anti-reflective coating is universally praised as the best smartphone display available.

• 2600 nit peak brightness with anti-reflective coating makes it the most sunlight-readable phone
• 120Hz LTPO refresh rate is butter smooth with excellent touch response

OnePlus 13R

Main camera and new 2x telephoto deliver solid results, but the 8MP ultrawide is a consistent weak point that drags down the system.

• The 50MP main camera produces sharp daylight stills with wide dynamic range and vibrant-but-accurate colors
• The new 50MP 2x telephoto is a significant upgrade over the old macro lens, delivering sharp images with nice colors
• The 8MP ultrawide is the clear weakness — soft, lacking detail, with limited dynamic range that reviewers universally criticize
• Video recording is limited: 4K restricted to select cameras with mediocre stabilization compared to the competition

Samsung Galaxy S25 Ultra

The quad camera system features an improved 200MP main sensor, 50MP ultrawide, 10MP 3x telephoto, and 50MP 5x periscope. Galaxy AI enhances post-processing significantly.

• 200MP main sensor produces incredibly detailed shots with improved noise handling
• Galaxy AI photo editing (Generative Edit, Best Face) is genuinely useful and well-implemented
• Video recording improvements with LOG support appeal to content creators
• Night mode still trails iPhone 16 Pro in very low light scenarios

OnePlus 13R

Snapdragon 8 Gen 3 delivers flagship-tier burst performance, but lab testing reveals significant thermal throttling under sustained workloads.

• Snapdragon 8 Gen 3 delivers exceptional burst performance, making it one of the most powerful phones at this price
• Day-to-day performance is silky smooth — no lag, hiccups, or slowdowns with OxygenOS optimizations
• Thermal throttling is a concern: 3DMark tests show GPU stability of only 54% with CPU throttling to 64% under extended load

Samsung Galaxy S25 Ultra

Snapdragon 8 Elite delivers the fastest Android performance available with excellent efficiency. 12GB RAM handles multitasking and AI workloads effortlessly.

• Snapdragon 8 Elite is a beast — fastest Android chip with significant efficiency gains
• On-device AI processing is noticeably faster than cloud-based alternatives
• Thermals are well-managed with the larger vapor chamber — no throttling in sustained use
