What the Galaxy S9+ Is and Why It Still Matters
The Samsung Galaxy S9+ launched in early 2018 as the premium large-screen sibling to the S9, and it remains a capable device years later. This evergreen profile covers its core hardware, camera capabilities, display quality, software experience, and practical longevity so you can understand its real-world value today. Rather than chasing short-lived hype, we focus on durable attributes, verified specifications, and long-term usability considerations for this device.
Design, Build, and Physical Usability
Materials, Fit and Finish
The S9+ features an aluminum frame with front and back glass, a design that was premium for its time and remains tactile and solid in hand. The device is IP68 rated for water and dust resistance, which adds durability in everyday use. The curved glass back with minimal antenna interruptions helps the phone feel cohesive, though it does require a case or screen protector to avoid long-term wear.
Dimensions, Buttons, and Ports
With a large 6.2-inch display, the S9+ is best suited for users who prefer bigger screens for media, reading, or multitasking. The side-mounted fingerprint sensor doubles as a home button with gesture support, and the familiar 3.5 mm headphone jack remains present for wired audio. USB-C handles charging and data, with USB 2. speeds typical for the generation, which is adequate but not class-leading in 2024.
Display and Visual Experience
Size, Resolution, and Panel Type
The S9+ uses a 6.2-inch Super AMOLED panel with a 1440 x 2960 resolution, delivering sharp text and vibrant colors typical of Samsung’s high-end AMOLEDs. The screen supports always-on display in a basic form and has good outdoor visibility, though it can struggle in extreme direct sunlight without raising brightness. For its age, the display remains enjoyable for video, gaming, and reading.
HDR and Color Accuracy
It supports HDR10 content and has strong out-of-the-box color saturation, which can be toned down via settings for more accurate viewing. Wide color gamut support and DCI-P3 coverage make it reasonably future-proof for media consumption, assuming content and streaming apps still align with its color profile.
Performance and Efficiency
Chipset and RAM Configuration
The S9+ typically ships with either the Snapdragon 845 (in many markets) or the Exynos 9810 (in some regions), paired with 6 GB of RAM. Both configurations deliver smooth day-to-day performance for browsing, messaging, video calls, and moderate gaming. Heavy multitasking and sustained high-end gaming can show thermal throttling, but typical use remains responsive.
Storage Options and Expandability
Storage choices generally include 64 GB or 128 GB, with no support for microSD expansion. The UFS 2.1 storage in the device is reasonably fast for app installs and photo loading, though write speeds can vary depending on file types and conditions. For most users, the built-in storage is adequate when managing apps and media actively.

Camera System and Imaging
Rear Cameras and Sensor Setup
On the back, the S9+ uses a dual-lens setup with a 12 MP wide-angle lens and a 12 MP telephoto lens, both with optical image stabilization. The dual aperture, branded as f/1.5 to f/2.4, allows the phone to adapt light intake depending on the scene, which improves low-light shots without excessive noise. The 2x optical zoom and high-quality bokeh make it well-suited for portraits and moderately distant subjects.
Low-Light and Software Processing
Night mode, introduced after the release via software updates, uses long exposure and multi-frame stacking to brighten scenes, though it can increase noise in certain textures. Colors are generally vivid by default, and you can choose between different picture styles in the camera settings. Video recording tops out at 4K at 30 fps, with steady gyro-EIS, which is solid for the generation but does not include 60 fps 4K.
Front Camera and Selfie Experience
The front-facing 8 MP camera produces acceptable selfies in good light, with decent auto HDR and face-detect features. Low-light selfie performance is limited, and detail is modest compared with contemporary flagships, but it is serviceable for video calls and casual social sharing.
Software, Updates, and Ecosystem
Operating System and Feature Set
The S9+ originally shipped with Android 8.0 Oreo, with major updates including Android 9 Pie and Android 10. Samsung’s One UI 1.x and 2.x layers refine the experience with better gestures, edge panels, and dark mode. These software capabilities help the phone remain usable and organized, despite its age.
Security Updates and Longevity
Samsung provided security patches for several years, but ongoing support has largely ended. Without the latest security updates, continued use on untrusted networks or for sensitive transactions increases risk. For many users, app compatibility and performance will remain acceptable longer than official update availability.
Samsung Ecosystem Integration
Integration with Samsung ecosystem features — such as Samsung Health, Knox security, DeX desktop experience, and SmartThings — remains functional and adds practical value if you use other Samsung devices. Cloud backups and cross-device clipboard features work reliably when enabled.
Battery, Connectivity, and Real-World Endurance
Battery Life and Charging
The 3500 mAh battery typically supports a full day of mixed use, including internet browsing, social apps, and occasional media. Heavy video playback or navigation can require top-ups mid-day. Quick Charge 2.0/3.0 helps restore charge efficiently, and wireless charging is supported for compatible mats.
Connectivity and Audio
Connectivity options include LTE Category 15, dual-band Wi-Fi, Bluetooth 5, NFC, and USB-C. Call quality is clear, and speakers remain decent for hands-free use. The retained 3.5 mm jack reduces adapter needs, which is appreciated by users of wired headphones.
Practical Considerations and Verdict
Strengths and Limitations
- Large, high-quality AMOLED display with good outdoor visibility.
- Versatile dual-camera system with strong portrait and low-light performance for its era.
- Premium build, IP68 rating, and retained 3.5 mm headphone jack.
- 6 GB of RAM and sufficient storage for most daily tasks and app collections.
- Limited update support and lack of microSD can constrain long-term use.
- No 90 Hz or higher refresh rate, and moderate low-light video capabilities.
Who Should Consider the S9+ in 2024 and Beyond
The Galaxy S9+ can still serve users who prioritize a large screen, solid cameras, and Samsung’s software features, especially as a secondary or lightly used device. It is less ideal as a primary phone if you need the latest security patches, cutting-edge performance, or expandable storage. If you choose to use it, plan for secure Wi-Fi, limited sensitive transactions, and possibly a replacement within the next one to two years for safety and performance reasons.
