The Xiaomi Redmi Note 11 Pro+ offers a 108 MP main sensor, an impressive feature on paper for a mid-range smartphone. This high resolution promises highly detailed photos, capable of capturing fine elements in landscapes or complex scenes. However, several users wonder if this mode is really useful in practice, given the physical limitations of smartphone sensors and the software processing applied.
Maximum resolution and the size of generated files
The 108 MP mode produces images of approximately 12,000 x 9,000 pixels, or more than 100 million pixels per photo. These files are large: between 15 and 25 MB depending on the scene and details captured. For typical use on social networks or viewing on a smartphone, this resolution is often superfluous, as most platforms automatically resize images to a few thousand pixels.
However, for large format printing or extreme cropping, the 108 MP mode can retain details that a standard 12 or 48 MP mode would not allow.
Software processing limits detail perception
The Redmi Note 11 Pro+ uses pixel binning technology, which combines several sensor pixels to improve light sensitivity. In most default modes, the smartphone combines 9 pixels into 1, reducing the effective resolution to about 12 MP.
In 108 MP mode, the software processing does not combine the pixels in the same way, which can cause:
- Reduced light sensitivity
- More pronounced noise in dark areas
- An increase in processing time for the image
Thus, the 108 MP mode is ideal in daylight and on well-lit subjects, but less suitable in low light.
The visible advantages when cropping
The main utility of the 108 MP mode is the extreme cropping of images without significant loss of detail. For example, a group photo taken from a distance can be cropped to isolate a face or a particular object without the quality being too degraded.
Tests show that cropping an area representing 10% of the original image in 108 MP mode retains more precise details than the same operation on a 12 MP photo, useful for amateur photographers or users wishing to extract precise details.
The difference in low light is minimal
In low light, the 108 MP sensor does not surpass the standard 12 MP mode. The reduction of pixel binning results in less light captured per pixel, increasing noise and reducing sharpness.
Comparative tests conducted by independent laboratories show that:
- The 108 MP mode generates up to 30% more noise in dark areas
- The standard 12 MP mode offers sharper and more homogeneous images in these conditions
- Fine details are often less exploitable than in daylight images
As a result, the 108 MP mode does not provide tangible improvement at night, unless strong light sources are present.
Storage and speed constraints
108 MP images take up a lot of space and slow down the camera’s shutter. A user who wants to photograph several scenes quickly may find themselves with:
- A longer image processing time
- A storage space consumption multiplied by 5 to 8 compared to the standard mode
- A less smooth experience for photo series or videos integrating still images
These constraints limit the practical use of the 108 MP mode for daily shots or spontaneous captures.
When is the 108 MP mode really interesting?
Despite its limitations, the 108 MP mode becomes useful in certain specific situations:
- Bright landscapes where detail is important for printing or large format display
- Architecture and urban photography with complex patterns
- Extreme cropping to isolate elements in the image
- Macro photography from a distance, when the distance prevents getting closer to the subject
In these contexts, the maximum resolution allows taking advantage of the sensor’s capacity and producing usable images even after retouching or cropping.
