Nothing Phone (3a) Pro vs Samsung Galaxy S25 Ultra

Nothing Phone (3a) Pro

The 6.77-inch AMOLED display is a highlight, with 120Hz refresh rate, 3,000 nits peak HDR brightness, and 480Hz touch sampling. A massive upgrade from the Phone 2a's 1,300 nits, it delivers excellent outdoor readability, rich colors, and smooth scrolling. FHD+ resolution is standard for the price class but perfectly adequate.

• 3,000 nits peak HDR brightness with 120Hz refresh — excellent outdoor readability and smooth scrolling
• 480Hz touch sampling rate delivers responsive input — particularly noticeable in gaming and fast scrolling
• Nothing OS monochrome aesthetic underuses the AMOLED's color capabilities — feels understated for such a vibrant panel

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

Nothing Phone (3a) Pro

The Snapdragon 7s Gen 3 handles everyday tasks — social media, browsing, multitasking — without issue. However, it's the weakest area of the phone. Benchmark scores (~810K AnTuTu) trail competitors like the Poco X7 Pro, and gaming at high settings can stutter. Some reviewers experienced occasional lag, while others found it perfectly smooth for non-gaming use.

• Smooth for everyday tasks — social media, browsing, and productivity run without noticeable stutter
• Gaming performance actually worse than the older Phone 2a — Snapdragon 7s Gen 3 trails Dimensity 7200 Pro in GPU tasks
• Occasional sluggishness and lag reported during extended use sessions

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

Nothing Phone (3a) Pro

The camera system is the Nothing Phone (3a) Pro's biggest selling point. The 50MP main sensor with OIS delivers detailed, vibrant daylight shots, while the 50MP 3x periscope telephoto is virtually unheard of under $500 — producing excellent portraits and zoom shots. The 50MP selfie camera is above average. However, the 8MP ultrawide is a weak link, low-light performance divides opinion, and video is limited to 4K/30fps.

• 50MP 3x periscope telephoto is a genuine rarity under $500 — excellent for portraits with natural bokeh
• 50MP main sensor with OIS produces detailed, vibrant 12.5MP binned shots with good dynamic range in daylight
• 8MP ultrawide is a clear weak link — cannot record 1080p/60fps and lacks detail
• Video limited to 4K/30fps — no 4K/60fps option, and telephoto lacks 4K video entirely

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

Nothing Phone (3a) Pro

The 5,000mAh battery provides reliable all-day endurance with 50W wired charging reaching full in about an hour. GSMArena measured 13 hours 37 minutes of active use. Light users can stretch to two days. The notable absence is wireless charging — every single reviewer flags this as a missing feature at the $459 price point.

• 5,000mAh delivers reliable all-day battery with 13h37m active use measured — light users can get two days
• 50W wired charging reaches 60% in 30 minutes and full charge in about 1 hour
• No wireless charging at $459 — universally flagged as a missing feature when Pixel 8a includes it

Samsung Galaxy S25 Ultra

The 5000mAh battery paired with Snapdragon 8 Elite efficiency delivers solid all-day battery life, though charging speeds remain conservative.

• Easily lasts a full day with heavy use, and two days with moderate use
• 45W wired charging is adequate but slow compared to OnePlus and Xiaomi offerings
