Flagship Features Comparison Table

To help you understand how the Sony Xperia Z5 stacks up against other smartphones in its category, I’ve created this comprehensive comparison table:

As the table clearly shows, the Sony Xperia Z5 offers several standout features compared to its contemporaries, particularly its exceptional 23MP camera, waterproof design, and dedicated camera button.

Design and Build Quality

After using the Sony Xperia Z5 for several months, I can confidently say that its design and build quality are among its most impressive features. Sony has created a device that feels substantial without being heavy, premium without being flashy, and durable without sacrificing aesthetics.

The frosted glass back is not only visually striking but also practical – it’s significantly less prone to fingerprints than the glossy alternatives many competitors offered. The metal frame provides rigidity and contributes to the phone’s premium feel, while the slightly rounded edges make it comfortable to hold for extended periods.

One design element I particularly appreciate is the side-mounted fingerprint scanner integrated into the power button. This placement is ergonomically brilliant – my thumb naturally rests there when holding the phone, allowing for effortless unlocking without changing my grip. It’s astonishingly quick and reliable, recognizing my fingerprint almost instantaneously in most cases.

The physical camera button deserves special mention. In an era where manufacturers were eliminating dedicated buttons, Sony maintained this practical feature. Half-pressing to focus and fully pressing to capture mimics the experience of using a dedicated camera, which photographers like myself greatly appreciate.

Port placement is thoughtful and functional. The 3.5mm headphone jack sits atop the device, while the USB port on the bottom features a water-resistant flap that doesn’t impede regular charging. The SIM and microSD card slots are hidden beneath a single flap on the left edge, maintaining the clean aesthetic.

The Z5’s IP68 dust and water resistance rating provides peace of mind without compromising design. Unlike some waterproof devices that feel bulky or utilitarian, the Z5 seamlessly integrates this protection into its elegant form factor.

If I had to identify any design weakness, it would be that the frosted glass back, while beautiful, makes the phone somewhat slippery. I’d recommend a quality case to protect both this aesthetic element and the device itself from accidental drops.

Overall, Sony created a sophisticated, functional design that stands apart from its competitors with thoughtful features that enhance the user experience rather than merely following trends.

Display Quality and Performance

The 5.2-inch IPS LCD display on the Sony Xperia Z5 is a delight for everyday use, striking an excellent balance between quality and practical battery consumption.

With a Full HD resolution of 1080 x 1920 pixels (approximately 428 ppi), the screen delivers crisp text, vibrant colors, and excellent detail without the battery drain associated with higher-resolution displays.

Sony leverages its TRILUMINOS technology and X-Reality engine from its television division to enhance the visual experience. These technologies noticeably improve color reproduction and contrast, making photos, videos, and games appear more vibrant and lifelike.

I particularly noticed the difference when streaming Netflix content – shows like “Planet Earth” display stunning natural colors that many other smartphone displays tend to oversaturate.

Brightness is impressive, with the screen remaining visible even in direct sunlight. The adaptive brightness feature works efficiently, adjusting to ambient conditions without jarring transitions. At night, the screen can dim sufficiently for comfortable reading without straining the eyes.

Viewing angles are excellent, with minimal color shift when viewing from the sides – a common issue with some LCD panels. This makes sharing content with friends or watching videos while the phone is resting on a table much more enjoyable.

Touch responsiveness is another area where the Z5 excels. During my testing, the display registered every tap and swipe accurately, even when using the screen with slightly damp fingers (though not completely wet, despite the waterproof rating).

Sony has also included a glove mode option that increases touch sensitivity, which I found extremely useful during colder months when wearing gloves. This thoughtful feature demonstrates Sony’s attention to practical, real-world usage scenarios.

While some competitors offered higher resolution displays at the time, the Z5’s 1080p resolution remains more than sufficient for a screen of this size. The decision to prioritize battery efficiency and consistent performance over unnecessary pixel density reflects Sony’s practical approach to smartphone design.

For those who enjoy customizing their display experience, Sony provides options to adjust white balance and enhance image quality through the X-Reality and Super-vivid modes. These features allow users to tailor the viewing experience to their personal preferences.

During my months of testing, the display has proven durable, showing no signs of scratching despite daily use without a screen protector – though I would still recommend one for long-term protection.

Camera Capabilities

The camera system on the Sony Xperia Z5 represents one of the device’s standout features and was revolutionary for its time. Boasting a 23MP rear sensor with f/2.0 aperture, the Z5’s camera delivers exceptional detail and clarity in a wide range of shooting conditions.

What truly impressed me about this camera is the lightning-fast hybrid autofocus system that Sony claims can lock focus in just 0.03 seconds. During my testing, this claim held up remarkably well – the camera consistently focused on subjects almost instantaneously, allowing me to capture spontaneous moments that would otherwise be missed with slower focusing systems.

The dedicated physical camera button enhances the photography experience significantly. Not only does it allow quick access to the camera app with a long press (even when the phone is locked), but it also provides the familiar two-stage mechanism photographers love: half-press to focus, full-press to capture.

This simple feature dramatically improves the photography experience compared to on-screen buttons.

In good lighting conditions, the camera produces stunningly detailed images with excellent color reproduction. The automatic white balance is generally accurate, producing natural-looking colors without the excessive saturation many smartphone cameras default to.

The dynamic range is impressive for a smartphone of this generation, capturing both shadow and highlight detail in challenging lighting situations.

Low-light performance is where many smartphone cameras struggle, but the Xperia Z5 performs admirably. While there is some inevitable noise in very dark scenes, the camera’s Superior Auto mode intelligently adjusts settings to balance detail preservation and noise reduction.

The results are better than most competitors from the same era, though not quite matching today’s night mode capabilities.

Video capabilities are equally impressive, with the ability to record 4K video at 30fps or 1080p at 60fps. The electronic stabilization does a reasonable job of smoothing out minor hand movements, though it’s not as effective as the optical image stabilization systems found in some competing devices.

The front-facing 5.1MP camera performs well for selfies and video calls, offering good detail and flattering skin tones. While not class-leading, it’s more than adequate for social media sharing and video conferencing.

Sony’s camera app deserves special mention for its balance of simplicity and advanced features. The Superior Auto mode handles most situations admirably, but more experienced photographers will appreciate the Manual mode, which offers control over focus, shutter speed, ISO, and white balance. Additional features like AR effects, Sweep Panorama, and 4K video recording expand the creative possibilities.

During my months of testing, I’ve consistently reached for the Xperia Z5 to capture important moments, often preferring it over dedicated cameras for casual photography due to its combination of image quality, speed, and convenience.

Performance and User Experience

The Sony Xperia Z5 is powered by the Qualcomm Snapdragon 810 octa-core processor paired with 3GB of RAM, a flagship configuration that delivers smooth and responsive performance for most tasks. Throughout my daily usage, which includes email management, social media browsing, video streaming, and moderate gaming, the Z5 handled everything with minimal lag or slowdown.

App launching is snappy, and multitasking between several applications occurs without noticeable performance degradation. The 3GB of RAM, while modest by today’s standards, proves sufficient for maintaining several apps in memory without aggressive background killing.

One area where early Snapdragon 810 devices received criticism was thermal management, with reports of overheating during intensive tasks. Sony addressed this concern in the Z5 with improved thermal management, and during my testing, the device remained comfortably warm even during extended gaming sessions.

There were occasional instances of heat buildup when recording 4K video for more than a few minutes, but nothing that affected functionality.

Gaming performance is impressive for a device of its generation. Titles like Asphalt 9, PUBG Mobile (on balanced settings), and Call of Duty Mobile run smoothly with few frame drops. More casual games perform flawlessly.

The Adreno 430 GPU handles graphically intensive applications admirably, though you may need to lower settings on the most demanding modern titles.

The user interface, running on Android with Sony’s custom skin, strikes a good balance between functionality and aesthetics. Sony’s modifications add value without overwhelming Android’s core experience, with useful additions like:

• Small Apps: Floating windows for multitasking
• Battery STAMINA mode: Intelligent battery saving features
• Theme support: For personalization
• PlayStation integration: For gamers in the Sony ecosystem

Sony’s approach to Android is refreshingly clean compared to some heavily modified interfaces from competitors. Bloatware is minimal and mostly comprised of Sony’s own services, many of which add genuine value.

Storage performance is solid with the 32GB of internal memory, supplemented by microSD expansion support up to 256GB. This hybrid approach offers both the speed of internal storage for system files and apps, with the flexibility of expandable storage for media.

Biometric security via the side-mounted fingerprint sensor deserves special mention for its speed and reliability. The sensor consistently recognizes my fingerprint on the first attempt, and its placement on the power button means the phone is unlocked by the time I’ve picked it up – a feature many modern phones still struggle to perfect.

Network connectivity has been reliable across multiple carriers, with strong signal reception and stable LTE connections. Call quality is excellent, with the noise-cancelling microphone effectively filtering out background noise for clear conversations.

Overall, the performance of the Xperia Z5 demonstrates Sony’s commitment to providing a premium user experience that balances power and efficiency. While it may not match the raw benchmarks of today’s flagship devices, it remains more than capable of handling everyday tasks with aplomb.

Battery Life and Charging

The Sony Xperia Z5 comes equipped with a 2900mAh non-removable battery, which might seem modest by today’s standards but delivers respectable endurance through intelligent power management. In my real-world testing, the battery performance offers a mixed yet generally satisfactory experience.

Under typical daily usage – including email, social media, web browsing, occasional photography, and about an hour of streaming video – I consistently achieved around 24-30 hours of battery life. This translates to a full day of moderate use without anxiety, though heavy users might need to reach for a charger by evening.

Sony’s STAMINA mode is one of the most effective battery-saving implementations I’ve encountered. When activated, it intelligently restricts background data, reduces performance, and limits vibration and display features to dramatically extend battery life.

In testing, enabling STAMINA mode at 30% remaining battery often allowed me to squeeze an additional 6-8 hours of essential use – a potential lifesaver when away from charging opportunities.

The Ultra STAMINA mode takes this even further, essentially transforming the Z5 into a feature phone with access only to basic functions like calls, texts, and a limited selection of apps. This extreme power-saving mode can extend battery life to multiple days when needed in emergency situations.

When it comes to recharging, the Z5 supports Qualcomm Quick Charge 2.0 technology, which delivers significantly faster charging speeds compared to conventional methods. Using the included fast charger, I could reliably achieve:

• 0-50% in approximately 30 minutes
• Full charge in about 1 hour 45 minutes

This rapid charging capability partially compensates for the modest battery capacity, allowing quick top-ups when time is limited. However, it’s worth noting that the Z5 lacks wireless charging – a feature some competitors offered at the time.

Battery degradation over time is inevitable with all lithium-ion batteries, and after extended use, many Z5 users report noticeable capacity reduction. In my experience, after about two years of use, the battery efficiency decreased by approximately 15-20%, requiring more frequent charging.

Heat management during charging is generally good, with the phone becoming warm but never uncomfortably hot – an important consideration given the glass construction of the device.

One particularly impressive aspect of the Z5’s battery management is its standby time. When left idle, the battery drain is minimal thanks to effective doze mode implementation, with the phone losing only 3-5% battery overnight – much better than many Android devices of the same era.

For travelers, the quick charge capability and effective power-saving modes make the Z5 a reliable companion, though I would recommend carrying a portable battery pack for extended trips or days with heavy usage.

Waterproof Capabilities: Truth vs. Marketing

One of the most heavily marketed features of the Sony Xperia Z5 was its IP68 water and dust resistance rating. This certification technically means the device is protected against dust ingress and can withstand immersion in water beyond 1 meter for up to 30 minutes. But how does this translate to real-world use? Let me share my honest experience.

During my testing, I’ve found the waterproof capabilities of the Z5 to be both impressive and subject to important limitations. The phone has survived numerous encounters with rain, spilled drinks, and even brief dunks in water without any adverse effects. Being able to take calls in the rain or use the phone with wet hands provides genuine peace of mind that many other devices simply don’t offer.

However, Sony’s marketing and the reality of the waterproofing deserve some clarification. Shortly after the Z5’s release, Sony actually revised their recommendations, advising against deliberately submerging the phone despite its IP68 rating. This created some confusion among users expecting a fully submersible device.

In my personal testing, I found the water resistance to be reliable for:

• Rain exposure (even heavy downpours)
• Accidental spills on the device
• Using the phone with wet hands
• Brief accidental submersion (such as dropping in a sink)
• Taking photos in light rain

However, I would not recommend:

• Taking underwater photos or videos
• Using the phone in pool or salt water
• Exposing the phone to hot water or steam
• Submerging the phone for extended periods

The reason for these limitations is practical: while the factory-sealed device meets IP68 standards, the water resistance relies on rubber seals around the ports and card slots that can degrade over time or if not properly closed. Additionally, water damage is typically not covered under warranty, regardless of the IP rating.

One design aspect I appreciate is that the Z5 achieves its water resistance while maintaining a standard 3.5mm headphone jack and micro-USB port without requiring cumbersome port covers (except for the SIM/SD card slot). This makes the water resistance feature more practical for everyday use, as you’re not constantly dealing with port covers like on some earlier waterproof phones.

It’s also worth noting that the touchscreen has limited functionality when wet – water droplets can register as touches or prevent actual touches from registering correctly. This is a physical limitation of capacitive touchscreens rather than a flaw in the Z5’s design.

In conclusion, while the waterproofing on the Xperia Z5 shouldn’t be treated as an invitation to use the phone as an underwater camera, it provides excellent protection against the most common water-related accidents that damage smartphones. Consider it insurance against accidents rather than a feature to regularly test, and you’ll likely be satisfied with this aspect of the device.

Audio Quality and Entertainment

The Sony Xperia Z5 delivers an exceptional audio experience that reflects Sony’s deep heritage in audio technology. As someone who values sound quality, this aspect of the phone has consistently impressed me during my months of testing.

Starting with the front-facing stereo speakers, the Z5 produces clear, loud audio that makes watching videos and playing games much more immersive compared to phones with a single bottom-firing speaker. While they don’t quite match the volume of some dedicated stereo speaker phones, the quality of the sound is excellent, with good separation and minimal distortion even at higher volumes.

Where the Z5 truly shines is in headphone audio quality. The device supports Hi-Res Audio and LDAC technology, delivering audio quality that approaches studio-grade reproduction when paired with compatible headphones. Even with standard headphones, the sound quality is noticeably superior to many competing smartphones, with rich, detailed audio that reveals nuances in music that are often lost on lesser devices.

Sony has included several audio enhancement technologies:

• DSEE HX: Upscales compressed music files to near high-resolution quality
• Digital Noise Cancelling: Reduces ambient noise when using compatible headphones
• ClearAudio+: Automatically optimizes sound settings for a balanced audio experience
• Dynamic normalizer: Balances volume levels between different tracks

These aren’t just marketing gimmicks – the difference is audible, particularly when listening to high-quality music files or streaming services. As a music enthusiast, I find myself preferring the Z5 for audio playback over many newer devices.

The 3.5mm headphone jack is a feature that many newer phones have abandoned, but its presence on the Z5 allows for use with high-quality wired headphones without adapters. The output is powerful enough to drive even higher-impedance headphones adequately.

For Bluetooth audio, the Z5 supports aptX and Sony’s proprietary LDAC codec, providing superior wireless audio quality when paired with compatible headphones or speakers. Connection stability is excellent, maintaining a solid connection even with the phone in my pocket or bag.

The entertainment experience extends beyond audio quality. The 5.2-inch Full HD display offers excellent color reproduction and viewing angles for enjoying videos and games. Netflix, YouTube, and other streaming services look fantastic, with the TRILUMINOS display technology delivering vibrant but natural colors.

Sony’s close relationship with PlayStation is evident in the PS4 Remote Play feature, which allows you to stream games from your PlayStation 4 console to the phone. While this requires a good Wi-Fi connection and is better suited to certain game genres, it’s an excellent addition for PlayStation owners.

The Z5 also comes with Sony’s media apps, including Album (for photos), Music, and Video, which offer clean interfaces and good functionality. While many users may prefer third-party apps, Sony’s offerings are certainly capable and integrate well with the overall experience.

For those who enjoy creating content, the Z5’s powerful camera combined with Sony’s editing apps makes it a versatile tool for capturing and sharing moments. The 4K video recording capability, while limited to shorter clips due to heat management, produces stunning results that look excellent on larger screens.

Software and User Interface

The Sony Xperia Z5 launched with Android 5.1.1 Lollipop and has since been updated to Android 7.0 Nougat, which represents the end of its official update cycle. Sony’s approach to Android has always been relatively light compared to some competitors, maintaining many of stock Android’s strengths while adding thoughtful features and optimizations.

The user interface is clean and intuitive, avoiding the excessive visual flourishes and bloatware that plague some manufacturer skins. Sony’s modifications are generally purposeful, focusing on enhancing functionality rather than changing the look and feel for its own sake.

After using the phone for several months, I’ve come to appreciate several aspects of Sony’s software approach:

Home Screen and App Drawer: Sony’s launcher is efficient and customizable, offering a traditional home screen and app drawer arrangement. The ability to sort apps alphabetically or by installation date is a simple but useful feature. The home screen supports both widgets and themes for personalization.

Sony Apps Suite: Unlike some manufacturers who duplicate every Google app, Sony’s pre-installed applications focus on areas where they can add value:

• Album: An excellent photo gallery with powerful organization features
• Music: A capable music player with integration for Sony’s audio enhancement technologies
• Video: A straightforward video player that handles most formats well
• What’s New: Showcases new content from Sony’s ecosystem (though this is admittedly less useful)

Most of these apps add genuine value rather than simply duplicating Google’s offerings.

Small Apps: This multitasking feature lets you run miniature app windows over your current screen. While not as sophisticated as modern split-screen implementations, it’s useful for quick calculations, note-taking, or browsing while using another app.

Themes: The theme engine allows for comprehensive visual customization, changing the look of system elements, icons, and backgrounds. Many themes are available for purchase, but several quality options are included for free.

Performance Optimizations: Sony includes several features to help maintain performance over time:

• Smart cleaner: Automatically frees up memory and storage
• Battery care: Helps maintain battery health by adapting charging patterns
• Xperia Actions: Contextual settings that adapt to your usage

The settings menu is well-organized and includes a search function, making it easy to find specific options without digging through multiple menus. Sony has also included a useful “Quick settings” section at the top level, providing access to commonly used toggles.

Software stability has been excellent in my experience, with very few crashes or unexpected behaviors. Apps run smoothly, and the system animations are fluid and responsive.

While the Z5 is no longer receiving major Android updates, Sony did provide security updates for a respectable period, and the Android 7.0 Nougat that it runs is still functional for most everyday tasks. However, this does mean that newer Android features and security enhancements are not available, which is an important consideration for security-conscious users.

For those comfortable with alternative solutions, the Z5 has a relatively active community of custom ROM developers, potentially extending its software lifespan beyond official support. However, this route requires technical knowledge and comes with its own set of compromises.

Overall, Sony’s software approach on the Xperia Z5 prioritizes functionality and stability over flashy features, resulting in a user experience that remains pleasant and usable even as the device ages.
