Samsung heavily promoted the S9+'s camera as "reimagined," and after extensive testing, I can attest that this isn't mere marketing hyperbole. The dual 12MP rear camera system introduces several innovative features that set new standards for mobile photography.
The primary camera boasts a variable aperture system, capable of switching between f/1.5 and f/2.4. This mechanical adjustment allows the camera to adapt to different lighting conditions automatically. In low light scenarios, the f/1.5 aperture captures significantly more light, resulting in brighter, clearer images with reduced noise. In well-lit environments, the f/2.4 aperture provides sharper images with a wider depth of field.
The secondary 12MP camera offers 2x optical zoom with a fixed f/2.4 aperture. This telephoto lens not only allows for closer shots without quality loss but also enables the popular Live Focus mode for adjustable background blur.
Both rear cameras feature optical image stabilization (OIS) and use dual-pixel phase detection autofocus (PDAF) for rapid and accurate focusing. In my testing, I found the autofocus to be almost instantaneous, even in challenging lighting conditions.
The S9+ introduces 960 fps super slow-motion video recording, a feature that can create stunning footage when used correctly. However, it's worth noting that this mode is limited to 720p resolution and requires good lighting to achieve optimal results.
Image quality from the S9+ is generally excellent, with vibrant colors, high dynamic range, and plenty of detail. The Pro mode offers manual control over ISO, shutter speed, and other parameters, allowing for creative shots that rival those from dedicated cameras.
The 8MP front-facing camera with its f/1.7 aperture performs admirably in various lighting conditions, producing detailed selfies with natural skin tones. The addition of AR Emoji, while somewhat gimmicky, showcases Samsung's foray into augmented reality applications.
Battery Life and Charging: Balancing Power and Efficiency
The Galaxy S9+ is equipped with a 3500mAh non-removable battery, the same capacity as its predecessor. However, thanks to the more efficient 10nm processor and software optimizations, the S9+ generally delivers improved battery life compared to the S8+.
In my rigorous testing, which included a mix of tasks such as web browsing, social media use, video streaming, and gaming, the S9+ consistently provided a full day of moderate to heavy use. On average, I achieved between 5 to 6 hours of screen-on time, which is commendable for a device with such a large, high-resolution display.
The device supports fast charging through Qualcomm Quick Charge 2.0 and Samsung's Adaptive Fast Charging. In my charging tests, the S9+ reached 50% battery capacity in about 30 minutes and achieved a full charge in approximately 1 hour and 45 minutes. While not the fastest charging speeds available, they are more than adequate for most users.
