Nothing Phone (3a) Pro vs Xiaomi 15 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

Xiaomi 15 Ultra

A stunning 6.73-inch 2K LTPO AMOLED with 120Hz, 3,200 nits peak brightness, and Dolby Vision support.

• 3,200 nits peak brightness is the highest of any smartphone tested, with excellent outdoor visibility and HDR performance
• 2K resolution with 120Hz LTPO delivers incredibly sharp, smooth visuals for gaming and media consumption

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

Xiaomi 15 Ultra

Snapdragon 8 Elite with 16GB RAM delivers the fastest Android performance available with excellent thermal management.

• Snapdragon 8 Elite with 16GB RAM makes this one of the fastest phones tested — no app or game can slow it down
• Liquid cooling system keeps sustained performance high with minimal throttling during extended gaming sessions
• 16GB RAM ensures smooth multitasking with dozens of apps in memory and efficient AI processing

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

Xiaomi 15 Ultra

The crown jewel — a triple Leica camera system with a 1-inch main sensor, 200MP telephoto, and 50MP ultrawide that redefines smartphone photography.

• The 1-inch main sensor captures more light and detail than any competing smartphone camera — photos have a depth and quality that approaches dedicated cameras
• 200MP telephoto with 4.3x optical zoom produces incredibly detailed zoom shots that rival the Galaxy S25 Ultra's 5x periscope
• Leica color science produces warm, film-like tones with natural skin rendering that photographers love
• Video stabilization is the best on any Android phone, though color consistency and dynamic range in video still trail the iPhone
