If you've ever picked up a Xiaomi smartphone and looked at the camera specs, you've probably seen the 48MP number in the core module description. Manufacturers are advertising this value, but what does it really mean for photo quality? Why do some models with a 48MP camera make great pictures, and others are blurry and noisy? And most importantly: should we overpay for this resolution?
In this article, we will understand how the 48-megapixel sensor in Xiaomi smartphones (including the Redmi models, POCO And the flagship series, how does it differ from the traditional 12MP or 108MP cameras, and when high resolution is really useful, we'll also test real-world examples of photos, compare them to competitors, and give you customization recommendations for better results.
What are megapixels and how do they work in smartphones
A megapixel (MP) is a million pixels, the dots that make up a photograph. The more megapixels, the more detail you get, all else being equal. But in the case of smartphones, the other equals are extremely rare: not only megapixels, but also sensor size, lens optical characteristics, processing algorithms and even software affect photo quality.
Xiaomi. 48-Megapixel cameras have been introduced in 2019 The year with the release of the Redmi Note 7 Pro (Sony sensor) IMX586). Since then, the technology has evolved: modern models use Samsung sensors. GM1/GM2, Sony IMX582/IMX682/IMX707 But the basic idea is that the high resolution is achieved by pixel binning (combining neighboring pixels).
- 📱 Without binning: the sensor shoots in full 48 MP, but the files are huge (10-15 MB), and the detail is manifested only with 100% increase.
- 🔍 With binning. 4-in-1: 4 neighboring pixels are combined into one “superpixel”, the final resolution is 12 MP, but light sensitivity improves and noise decreases.
- 🌙 Night mode: often uses binning 9-in-1 or 16-in-1 Maximize brightness in the dark (resolution drops to 3-6 MP).
It’s important to understand that the 48 MP in Xiaomi is not a guarantee of the best photos, but a tool that needs to be used correctly. For example, when shooting in automatic mode, the camera most often saves 12 MP (with binning), and the full 48 MP is turned on only in manual mode or under special settings.
48 MP vs 12 MP vs 108 MP: which is better for photos
To find out whether 48 megapixels are better than the traditional 12 MP or the ultra-modern 108 MP, compare the key parameters using the example of popular Xiaomi models:
| Parameter | 12 MP (e.g. Mi 11 Lite) | 48 MP (e.g. Redmi Note 12 Pro)+) | 108 MP (e.g. Xiaomi 13 Ultra) |
|---|---|---|---|
| Sensor size | 1/2.55" | 1/1.28" – 1/1.56" | 1/1.12" |
| Pixel size (without binning) | 1.4 μm | 0.8-1.2 μm | 0.8 μm |
| Pixel size (with binning) 4-in-1) | — | 1.6-2.4 μm | 1.6 μm |
| Details in good lighting | Good (enough to print) A4) | Excellent (can be sprinkled without loss) | Maximum (suitable for professional processing) |
| Quality in the dark | Medium (noises at the time of the ISO > 1600) | Good (binning improves light strength) | Excellent (large sensor) + advanced algorithms) |
And you can see from the table that 48 MP is a trade-off between detail and light sensitivity. 12MP cameras often lose resolution but win in low light clarity. 108MP give maximum detail, but require a powerful processor to process and take up a lot of memory space.
⚠️ Note: If you shoot only for social networks (where photos are compressed to 2-3 MP), the difference between 12 MP and 48 MP will be almost invisible.
How to Enable Full 48MP Shooting on Xiaomi
By default, most Xiaomi smartphones save 12MP photos (with binning) to save space and speed up processing. To use the full 48 megapixels, you need to manually change the settings. Here is a step-by-step instruction:
- Open the standard Camera app.
- Touch the icons ⚙️ Settings (or swipe up/side down depending on the model).
- Find the photo resolution or aspect ratio section.
- Select the 48MP option or 48M (It can be called High Resolution).
- In some models (for example, POCO F5) You need to additionally turn on Pro Mode and manually set the permission.
After activating 48 MP, pay attention to the following nuances:
- 📸 Files will weigh 3-4 times more (up to 20 MB per photo).
- 🐢 Shooting in RAW (If it is supported, it will take up more space.
- ⚡ In the dark, quality may deteriorate due to lack of binning.
Make sure there is enough memory on the phone
Shut down. HDR (It can make the detail worse)
Use a tripod or stable surface
Shoot in good lighting-->
If the 48MP option is not available in the settings, this may mean:
- 📱 Your Xiaomi model uses software-based resolution enhancement (interpolation) instead of the real 48MP. 9A has a 13-megapixel camera, but the specifications can be specified “up to 48 MP” due to the software.
- 🔧 Firmware update required (check in Settings) → The phone. → Updating the system).
When 48MP is Really Useful: 5 Real-world Scenarios
High resolution isn’t always the same as a good photo, but there are situations where 48 megapixels give a noticeable advantage:
- Crop (trimming) photos. If you need to cut a part of the frame (for example, to zoom in on a group photo), 48 MP will allow you to do this without a lot of loss of quality. At 12 MP after the crop, the image will become "soapy".
- Printing in large formats. Printing on a poster size A3 (297×420 mm) with a permit 300 dpi is required ~13 MP. 48 MPs provide a margin for printing without artifacts.
- Taking pictures of textures and fine details, for example, if you're photographing jewelry, electronics or natural objects (leaves, insects), the high-detailedness will help you to see the little things.
- Videotaped in 8K. Some flagships of Xiaomi (for example, Xiaomi) 13 Pro) are used 48-Megapixel sensor for recording video in resolution 7680×4320 (8K), wherein matters.
- Professional post-processing. RAW (dng format) 48 MP gives more room for exposure correction, white and color balance without loss of quality.
In other cases (home photos, selfies, social media), the difference between 12 MP and 48 MP will be minimal, and in some scenarios, 12-megapixel photos may look better due to more aggressive binning and noise cancellation.
💡
If you are shooting for Instagram or Telegram, turn on the option “Save a copy for social networks” in the camera settings – this will reduce the file size without losing visual quality.
Xiaomi’s 48-megapixel camera myths: what’s true and what’s not
There are many myths surrounding high-resolution smartphones, and we'll look at the most popular ones.
- 🔍 Myth 1: “The more megapixels, the better the camera.” Reality: The quality of the photo depends on a set of factors: sensor size, lens aperture, processing algorithms. For example, an iPhone 13 with 12 MP often shoots better than many 48-megapixel smartphones.
- 📸 Myth 2: "48 MP is only for professionals." Reality: Even a beginner can appreciate the benefits of high resolution if he often crops or prints photos. But for most tasks, 12 MP is enough.
- 💰 Myth 3: "48MP smartphones are always more expensive." Reality: The technology has long gone mainstream. For example, the Redmi Note 12 Pro with a 50MP camera is cheaper than an iPhone. SE 12 MP.
- 🌃 Myth 4: "48 MP improves shooting at night." Reality: Conversely, in the dark, the camera automatically goes into binning mode (12 MP or less) to reduce noise. High resolution is only useful in good lighting.
⚠️ Note: Some manufacturers (including Xiaomi in budget models) use interpolation - software increase in resolution from 12-13 MP to 48 MP. Such photos do not contain real detail, but only "bloated" by algorithms. Check the real characteristics of the sensor on the GSMArena website.
48 MP comparison in different Xiaomi models: who shoots better
Not all 48MP cameras are the same. Even within Xiaomi's lineup, the difference can be huge.
| Model | Sensor | Sensor size | Features | Quality assessment (1-5) |
|---|---|---|---|---|
| Redmi Note 10 Pro | Samsung S5KHM2 (108 MP, binning to 12/27/108 MP) | 1/1.52" | Support 8K Video but weak optical stabilization | 4/5 |
| POCO X4 Pro 5G | Sony IMX582 (48MP, binning 4-in-1) | 1/2" | Good color reproduction, but it makes noise at dusk | 3.5/5 |
| Xiaomi 12T Pro | Sony IMX707 (200 MP, binning to 12/50 MP) | 1/1.22" | Best detail in the lineup, but overheats during long shooting | 5/5 |
| Redmi 9T | Samsung S5KJN1 (48 MP, interpolation from 12 MP) | 1/2" | Budget option with mediocre quality | 2.5/5 |
As the table shows, even within a single brand, the difference between models is huge.Flagship smartphones (Xiaomi) 12T Pro, Xiaomi 13 Ultra) uses large sensors (1/1.12" – 1/1.28") real-life 48+ Megapixels, whereas budget models (Redmi) 9T) often bypass interpolation.
If you are interested in the camera, pay attention not only to megapixels, but also to:
- 📏 Sensor size (the more inches, the better the aperture).
- 🔍 Aperture (f/1.7–f/1.9 preferably f/2.2).
- 🤖 The Snapdragon 8 Gen 2 or Dimensity 9000 processors faster than the Snapdragon. 6xx).
💡
In budget smartphones Xiaomi (up to 20 000) ₽) 48 MP often means interpolation or a weak sensor. For real advantage, choose models from 25,000. ₽ Sony-sensored IMX7xx.
How to improve photos on a 48-megapixel camera Xiaomi: 7 practical tips
Even with a good camera, you can get bad shots, if you don’t take into account the nuances of the shooting. Here are proven recommendations for Xiaomi owners with 48 MP:
- Take it down. RAW (If supported, turn on Pro mode → Keep in RAW. This will give you more data to post-process in Lightroom or Snapseed.
- Use a tripod or stabilize. At 48 MP, the slightest shaking of the hand causes blurring. Turn on Night Mode even during the day if the lighting is not perfect.
- Customize the exposure manually. In Pro mode, reduce the exposure. ISO before 100–400 and put the shutters on. 1/100–1/500 static.
- Turn off the digital zoom. When zooming in, the camera just cuts a 48-megapixel photo instead of using optics. Better take it without zoom, then cut it on the computer.
- Clean the lens. The dust and fingerprints on the lens are particularly noticeable at high resolution. Use microfiber.
- Experiment with aspect ratio. In the camera settings, choose 4:3 instead of 16:9, so the sensor uses the maximum area.
- Update your firmware. Xiaomi regularly improves photo processing algorithms. Check for updates to Settings → The phone.
If your model supports the shooting in HDR10+ (For example, Xiaomi 13 Pro, turn it on for a wider dynamic range. HDR Can "eat" details in the shadows at 48 MP.
