Hailed as one of the most advanced smartphones ever created, this device promises to redefine how we interact with technology. But does it live up to the hype? Is the Sony Xperia Z9 Ultra truly the best phone of 2025? In this comprehensive review, we’ll dive deep into every aspect of this groundbreaking device, from its design and display to its performance, camera capabilities, and more.
Design and Build Quality: A Masterclass in Engineering
When you first lay eyes on the Sony Xperia Z9 Ultra, it’s hard not to be impressed. The phone boasts a sleek, minimalist design that pays homage to Sony’s rich heritage in crafting premium electronics. Constructed with aerospace-grade aluminum and Gorilla Glass Victus+, the Xperia Z9 Ultra feels both luxurious and durable. Its slim profile and ergonomic curves make it comfortable to hold, even during extended use.
One standout feature is the IP68 water and dust resistance rating, which ensures that the Xperia Z9 Ultra can withstand accidental spills or exposure to harsh environments. This level of durability makes it an ideal choice for users who demand reliability without compromising style. Additionally, the absence of unnecessary bezels gives the phone a modern aesthetic, while the side-mounted fingerprint scanner doubles as a power button—a hallmark of Sony’s thoughtful engineering.
Sony has also introduced a new eco-friendly initiative with the Xperia Z9 Ultra. The packaging is entirely plastic-free, and some components are made from recycled materials. This commitment to sustainability adds another layer of appeal to an already impressive package.
Display: A Visual Feast
If there’s one area where Sony consistently excels, it’s display technology—and the Xperia Z9 Ultra is no exception. Equipped with a massive 6.9-inch OLED panel, this phone delivers breathtaking visuals with vibrant colors, deep blacks, and razor-sharp clarity. With a resolution of 4K HDR+ and a refresh rate of 120Hz, the Xperia Z9 Ultra offers a viewing experience that rivals even high-end televisions.
Whether you’re streaming your favorite movies, playing graphically intensive games, or simply browsing social media, the Xperia Z9 Ultra’s screen pulls you into its world.

In benchmark tests, the Xperia Z9 Ultra outperforms many competitors, achieving record-breaking scores across various categories. Gaming enthusiasts will appreciate the device’s ability to run AAA titles like Genshin Impact and Call of Duty: Mobile at maximum settings without any lag or overheating issues. Thanks to its vapor chamber cooling system, thermal management remains top-notch, allowing sustained peak performance over long periods.
Battery life is another critical factor when evaluating a smartphone’s overall usability. The Xperia Z9 Ultra houses a robust 5,000mAh battery that easily lasts two full days under moderate usage. Fast charging technology (up to 65W) ensures you can quickly top up your device, going from zero to 100% in just 35 minutes.

- A 200MP primary sensor with optical image stabilization (OIS), perfect for capturing ultra-detailed shots.
- A 12MP ultra-wide lens , ideal for expansive landscapes and group photos.
- A 16MP telephoto lens with 5x optical zoom, enabling crystal-clear close-ups.
The inclusion of Sony’s Exmor RS image sensor ensures superior low-light performance, reducing noise and preserving natural tones even in challenging environments. Features like AI-driven scene recognition, real-time tracking autofocus, and cinematic video recording at 8K resolution elevate the Xperia Z9 Ultra above its peers.

Software enhancements play a significant role in enhancing the photography experience. The Xperia Z9 Ultra runs on Android 15, optimized with Sony’s custom UI overlay. Tools like Photographic Pro Mode give users granular control over settings like ISO, shutter speed, and white balance, catering to professional photographers who value flexibility.
Audio Experience: Immersive Soundscapes
True to its roots as a leader in audio innovation, Sony has equipped the Xperia Z9 Ultra with class-leading sound capabilities. The device features stereo speakers tuned by Sony’s engineers, delivering rich, balanced audio with impressive volume output. Whether you’re watching videos, listening to music, or gaming, the immersive audio quality sets a new standard for mobile devices.
For audiophiles, the inclusion of a 3.5mm headphone jack alongside support for high-resolution audio formats like LDAC and DSEE Ultimate is a godsend. These features allow you to enjoy lossless music playback through wired headphones, preserving every nuance of your favorite tracks.
