All three smartphones offer large displays with ultra-premium finishes, but each takes a different approach.
The Oppo Find X8 Ultra stands out with its almost bezel-less 6.82-inch LTPO AMOLED panel. It supports QHD+ resolution, 120Hz refresh rate, and a peak brightness of 2500 nits. Its curved edges and symmetrical bezels give it a futuristic feel. Oppo also adds IP68/IP69 water and dust resistance, making it both stylish and durable.
The iPhone 16 Pro Max introduces a slightly larger 6.9-inch Super Retina XDR OLED display. While its resolution (2868 x 1320 at 460 ppi) isn’t as sharp as Oppo or Samsung, Apple focuses on balance and energy efficiency. With ProMotion (120Hz adaptive refresh) and excellent color calibration, it’s perfect for users who want accurate visuals and seamless responsiveness. Its titanium frame and Ceramic Shield front enhance its durability and premium build.
Samsung’s Galaxy S25 Ultra features a 6.9-inch Dynamic AMOLED 2X display with a 1440 x 3120 resolution and the highest peak brightness in the group. It’s vivid, sharp, and easily readable even in harsh sunlight. The use of Gorilla Glass Armor 2 and a solid titanium frame gives it a sturdy, industrial feel.
Verdict: Samsung wins on raw display quality, but Oppo delivers the sleekest design, while Apple prioritizes long-term visual consistency and balance.
Performance: Speed vs Efficiency
Each brand has equipped its flagship with the best chipset available, but performance isn’t just about raw power—it’s about optimization.
The iPhone 16 Pro Max, powered by Apple’s A18 Pro chip, is a benchmark leader in CPU efficiency and app responsiveness. With tightly integrated hardware and software, iOS 18 runs flawlessly, and the 8GB RAM is more than enough due to iOS’s superior memory management.
In contrast, the Oppo Find X8 Ultra and Samsung Galaxy S25 Ultra both use Qualcomm’s Snapdragon 8 Gen 4 platform, though Samsung uses a custom-optimized version. These chips offer exceptional multitasking, gaming, and AI capabilities. Oppo pairs this with up to 16GB of RAM and UFS 4.0 storage, ensuring lightning-fast app loading and data transfer speeds.
Samsung matches Oppo in performance but adds exclusive features through One UI 7—like enhanced stylus support and AI-powered task handling.
Verdict: iPhone offers the most consistent and efficient performance for everyday users. Oppo and Samsung offer more RAM and flexibility for power users and gamers.
Camera Systems: Photography Meets Innovation
In 2025, camera hardware is more advanced than ever, and all three phones cater to serious photographers—but with different strengths.
The Oppo Find X8 Ultra features an impressive quad-camera system: four 50MP sensors including a massive 1-inch main sensor, dual periscope lenses (3x and 6x optical zoom), and a 50MP ultra-wide. The result is stunning low-light performance, lossless zoom at multiple ranges, and detailed wide-angle shots. Oppo’s Hasselblad partnership adds pro-grade color tuning for more accurate tones.
The iPhone 16 Pro Max takes a different route. Apple focuses on image processing rather than sensor size. The 48MP main camera, 12MP ultra-wide, and 12MP 5x telephoto lens deliver natural-looking photos. Where it truly shines is in video—thanks to Apple ProRes, Dolby Vision HDR, and seamless 4K60fps recording, iPhone remains the go-to for content creators.
Samsung’s Galaxy S25 Ultra pushes hardware to the limit with a 200MP main sensor, 50MP ultra-wide, and two telephoto lenses (3x and 5x zoom). Samsung’s AI-driven processing helps balance highlights and shadows, and 8K video recording is as impressive as it is future-ready.
Verdict: For still photography, Oppo’s large sensor and optics offer unbeatable depth and realism. For video creators, iPhone remains the leader. Samsung wins on sheer versatility and zoom range.
Battery & Charging: Endurance vs Speed
The Oppo Find X8 Ultra is unmatched in battery capacity, with a reported 6100mAh battery. It also supports 100W wired charging and 50W wireless, which means you’ll spend far less time plugged in—even with heavy use.
The Galaxy S25 Ultra packs a 5000mAh battery with 45W wired and 15W wireless charging. It supports reverse wireless charging too, letting you power accessories or other devices on the go.
The iPhone 16 Pro Max is more conservative with its ~4685mAh battery and slower 27W wired charging. However, iOS’s energy efficiency ensures excellent screen-on time, and MagSafe wireless charging remains a convenient solution for Apple ecosystem users.
Verdict: Oppo wins for charging speed and battery capacity. Samsung offers balance. iPhone focuses on long-term battery health and efficiency.
Software & Ecosystem
Apple’s iOS 18 is the most polished and user-friendly OS, especially for those embedded in the Apple ecosystem. If you use AirPods, a MacBook, or an Apple Watch, the integration is seamless and hard to beat.
Samsung’s One UI 7 builds on Android 15 with deep customization, advanced multitasking, and integrated stylus features. It’s the best Android experience for productivity.
Oppo’s ColorOS 15 is sleek and snappy, with a strong focus on AI and visual design. It’s ideal for users who want a clean interface with powerful customization.
Verdict: iPhone wins for ecosystem integration, Samsung for productivity, and Oppo for interface design.
Connectivity
When it comes to connectivity, all three phones support 5G, Wi-Fi 6/7, Bluetooth 5.3+, and NFC, but each has its own strengths in global compatibility and advanced features.
- Oppo Find X8 Ultra features wide 5G band support, including SA/NSA bands, Wi-Fi 7, Bluetooth 5.4, and advanced GPS options like BDS, GALILEO, and QZSS. It also includes infrared and USB-C 3.2, offering strong versatility for power users.
- iPhone 16 Pro Max includes Wi-Fi 6E, Bluetooth 5.3, and advanced Ultra Wideband 2. While it doesn’t include an infrared port, it supports eSIM and satellite connectivity, making it ideal for emergency comms. It uses Lightning or USB-C depending on the region, adding some fragmentation.
- Samsung Galaxy S25 Ultra stands out with Wi-Fi 7, Bluetooth 5.3, UWB, and USB-C 3.2, plus broad GPS support. It also supports DeX, NFC, and dual physical SIM or eSIM depending on the model.
For connectivity, Samsung Galaxy S25 Ultra leads with the most complete package—Wi-Fi 7, Bluetooth 5.3, UWB, and flexible SIM support. Oppo Find X8 Ultra excels in global 5G and location accuracy, while iPhone 16 Pro Max offers cutting-edge UWB and satellite support but is slightly less flexible overall.
Final Thoughts: Which One Should You Buy?
- Choose the Oppo Find X8 Ultra if you want cutting-edge camera hardware, a stunning display, and unmatched charging speeds.
- Go with the iPhone 16 Pro Max if you value smooth performance, top-tier video recording, and seamless Apple ecosystem integration.
- Pick the Samsung Galaxy S25 Ultra if you need an all-rounder with excellent display, camera versatility, and productivity features like the S Pen.
Each of these flagships is excellent in its own right. Your choice ultimately depends on your priorities—camera performance, ecosystem, design, or battery life.
