48 MP camera in Xiaomi: what it means, how it works and whether to overpay

When you see the “48 MP camera” in Xiaomi’s smartphone specs, the logical question is: what does that mean in practice? Marketing numbers are often misleading, especially when it comes to megapixels. In this article, we’ll look at how the 48MP sensor in Xiaomi phones works, what technologies are behind it, and whether more megapixels = better photos.

There's endless debate about whether it's more important than megapixels or image processing. But in the case of Xiaomi, 48 MP is not just a tick-off number. The company uses this technology in segments ranging from the budget Redmi to the flagship Xiaomi 13 Ultra. But does it work equally well? Let's get to the bottom of it.

What is 48 MP in a smartphone camera and how does it work?

Megapixels (MPs) are the millions of pixels that make up a photo. The more of them, the more detail the image is potentially higher. But in smartphones, it's not that simple. The 48-megapixel sensor in Xiaomi is not always 48 MP at the output, and it's using pixel binning technology, which is a game-changer.

In most cases, a smartphone doesn't use all 48 MPs, but combines 4 pixels into one, producing a 12-megapixel photo at the output. Why? To improve light transmission and reduce noise. For example, in the dark, 48 MPs can give too "noisy" an image, and after pixel binning, the quality gets better. But with good lighting, you can turn on the full 48 MP mode and get maximum detail.

• 📷 48 MP: Maximum detail, but larger file size and possible low light noise.
• 🌙 12 MP (pixel binning): better light transmission, less noise, optimal for most scenes.
• 🔍 Digital zoom: 48 MPs allow you to cut out part of the frame with less quality loss.

It’s important to understand that the 48 MP in Xiaomi doesn’t automatically outperform the 12MP cameras of competitors.It all depends on the size of the sensor, the optimization of algorithms and the quality of the lens. For example, the iPhone 14 Pro with 12 MP often shoots better than some 48 MP smartphones due to advanced processing.

Xiaomi models are equipped with 48-MP camera: from budget to flagships

Xiaomi has been actively implementing 48-megapixel sensors since 2019, and today the technology is found in all price segments, from the Redmi Note 12 Pro to the Xiaomi 13T Pro. However, not all 48-megapixel cameras are the same: they differ in sensor size, aperture and supported features.

As you can see from the table, even inside the Xiaomi 48 MP lineup, it’s not always the same quality. For example, the Redmi Note 12 Pro+ and Xiaomi 13T both have 48 MP cameras, but the second one has a larger sensor (1/1.28” vs. 1/1.56”), which directly affects light absorption and dynamic range. And the flagship IMX989 in the 12S Ultra is in a different class altogether.

⚠️ Note: If you see in the characteristics of Xiaomi “48 MP” + 8 MP + 2 MP", this does not mean that all three cameras are 48 MP. Usually the main camera is 48 MP, and the rest are auxiliary (wide-angle and macro camera).

48 MP vs 108 MP vs 200 MP: what is better in Xiaomi smartphones

After 48MP sensors, Xiaomi has released models with 108 MP (Mi 10 Pro, Redmi Note 11 Pro+) and even 200 MP (Xiaomi 13 Ultra). The logical question is: if there are more “advanced” options, why even 48 MP? The answer lies in the balance between quality, price and practicality.

Let's compare the key differences:

• 📊 48 MP: optimal balance for most tasks: good detail, small file size, efficient pixel binning.
• 🔢 108 MP: More details with more 100% increase, but the files weigh in 2-3 Often overheating during long shooting.
• 🎯 200 MP: maximum detail for professionals, but requires perfect lighting conditions.

For example, the Xiaomi 13 Ultra with a 200 MP sensor should theoretically outperform all 48 MP models. But in practice, the difference is only noticeable when printing photos in large format or deep crop. For social networks or viewing on a smartphone screen, 48 MP is more than enough.

How to enable shooting in 48 MP on Xiaomi: step-by-step instructions

Many users do not even suspect that their Xiaomi supports shooting at a full 48 MP. By default, the camera often works in 12 MP (pixel binning).

1. Open the Camera app.
2. Touch the badge. ⚙️ Settings (or swipe up/side down depending on the model).
3. Find the resolution or aspect ratio section.
4. Select the 48 MP or Max resolution option.
5. Some models (e.g. Redmi Note 11 Pro+) need to additionally enable HEIF to shoot 48 MP without loss of quality.

After activation, you will notice that:

• 📸 Photos got heavier (10-15 MBT 3-5 MB in 12 MPP).
• 🔍 When you zoom in, you can see more detail (such as text on signage or tree leaves).
• ⚡ Shooting at 48 MP can drain the battery a little faster.

Make sure your phone has enough memory (48MP photos take up ~12MB each)

Turn off HDR manually if shooting in the dark (it can worsen detail)

Use a tripod for stability in low light

Check the save format (better HEIF than JPEG)

⚠️ Note: On some Xiaomi models (e.g, POCO X3 Pro) 48 MP mode can be hidden. To unlock it, go to the camera settings → Additionally. → Enable high resolution.

Pros and cons of 48-MP camera in Xiaomi: honest analysis

Like any technology, Xiaomi’s 48-megapixel sensors have their strengths and weaknesses.

Advantages:

• 🔍 Detailing: the ability to print photos in large format or magnify strongly without loss of quality.
• 🎞️ Fraternization flexibility: you can “cut” part of the frame in post-processing without losing resolution.
• 🌟 Pixel binning: in 12 MP mode, the camera shows excellent results in low light.
• 💰 Price: 48-MP smartphones Xiaomi is often cheaper than analogues with 108/200 CP with comparable quality.

Disadvantages:

• 📉 Noise in the dark: in a full 48 MP in poor lighting, photos can turn out to be “noisy».
• 🐢 Performance: 48MP photo processing requires more resources, which can lead to lags on budget models.
• 💾 Weight of files: one photo in 48 MP can weigh 10-15 MB, which fills up memory quickly.
• 🔋 Battery consumption: shooting and processing high-resolution photos increase energy consumption.

It's important to understand that 48MP is a tool, not a guarantee of perfect photos. For example, the Xiaomi 12T Pro with a 200MP camera in automatic mode often loses the Google Pixel 7 with a 12MP sensor because of the better processing of the latter.

💡

If you shoot for social networks (Instagram, VK), 48 MP is excessive - the platforms still compress the photo to 1-2 MP.

How to improve the quality of photos on a 48-MP camera Xiaomi: 7 practical tips

Even with a 48MP camera, you can get mediocre shots, if you don’t take into account the key nuances.

1. Use 48MP mode only in good lighting. At dusk or at night, it is better to switch to 12MP with pixel binning or activate Night mode.
2. Turn off the digital zoom. Instead, take a 48 MP shot and then cut the desired piece, so there's less quality loss.
3. Shoot in HEIF format. It saves more detail with less file weight than JPEG. Included in Camera Settings → Photo format.
4. Use manual settings. The Camera app has Pro mode where you can manually adjust ISO, shutter speed and white balance.
5. Clean the lens. Even small contaminants on the lens can ruin the detail of the 48-MP image. Use microfiber.
6. Shooting in RAW. If your model supports you RAW (For example, Xiaomi 13 Pro, shoot in this format for later processing in Lightroom.
7. Update the firmware. Xiaomi regularly improves image processing algorithms through MIUI updates.

To check the difference between modes, take a test shot of 12 MP and 48 MP under the same conditions, and then compare them on the big screen. You will be surprised how much different the level of detail!

💡

A 48 MP shot is only justified with sufficient lighting and maximum detail, and otherwise 12 MP with pixel binning will give the best result.
