If you've ever looked at the installed list on your Xiaomi smartphone, you've probably noticed a strange name, Opera Preinstall Data. It doesn't have a desktop shortcut, it doesn't show up in the app menu, but it takes up space in memory and periodically appears in the active process list. What is this mysterious component? Why is it preinstalled on your device? And most importantly, can it be safely removed without risking system stability?
Owners of Xiaomi, Redmi and POCO smartphones often encounter pre-installed services that are not always clear in their purpose. Opera Preinstall Data is one of such elements that raises more questions than it answers. In this article, we will discuss in detail what is behind this name, how it is associated with the Opera browser, and whether its presence on your phone is justified.
Now, let me just say, it's not a virus, it's not malware, but it doesn't have any useful functionality for most users. Let's get a little bit more into it.
What is Opera Preinstall Data and Where Does It Come From?
Opera Preinstall Data is a service package that is installed on Xiaomi smartphones as part of a partnership agreement between the company and the developers of the Opera browser. Its main task is to ensure that the Opera or Opera Mini browser is quickly set up initially if the user decides to install it. In fact, it is a set of pre-loaded data (cache, configuration files, localized settings) that speeds up the first launch of the browser and saves traffic when installing it.
Why Opera? Because Xiaomi is partnering with various services to pre-install their apps, which is beneficial to both parties: Opera gets an additional audience, and Xiaomi gets financial support or other bonuses, a practice common among many smartphone manufacturers, especially in the low-end and mid-market segments.
It is important to understand that Opera Preinstall Data is not the browser itself, but only an auxiliary module for it. It does not automatically launch the browser or collect your data without your knowledge. However, it takes up space in the device’s memory (usually from 10 to 50 MB) and can be updated periodically through Google Play if you have automatic updates for system applications enabled.
What Xiaomi devices do this package run on? Most often it is pre-installed on budget and mid-range models released after 2019, including:
- 📱 Redmi Note Series 8/9/10/11 and their modifications (Pro, Pro Max, Lite)
- 📱 Lineages POCO X3, X4, M3, M4 others
- 📱 Some Xiaomi Mi A models with Android One)
- 📱 Budget smartphones Redmi 9A, 10A, 10C similar
Why Xiaomi is installing Opera Preinstall Data?
The main reason for pre-installing this package is a commercial partnership, and Xiaomi, like many other vendors, monetizes pre-installed software, which reduces the final cost of the device for the buyer, as part of the cost is offset by partners. Here are the key reasons why Opera Preinstall Data is on your smartphone:
- 💰 Financial benefit for Xiaomi: The company receives a fee from Opera Software for pre-installing their services. The more devices with this package are sold, the higher the revenue.
- 🚀 Accelerated Browser Installation: If the user decides to install Opera or Opera Mini, the process will go faster, as some of the data is already downloaded.
- 📊 Anonymous statistics: The package can send data about the device model and region, but not personal information.
- 🔄 Automatic Updates: The package can be updated via Google Play, which ensures that the data is up-to-date for future browser installation.
Should we worry about privacy? Opera says the package does not collect personal user data such as browser history, passwords or cookies.
⚠️ Note: Opera Preinstall Data sends the following information to the developer servers: Your device model (e.g. Redmi Note 10 Pro) Operating System Version (Android 11, MIUI 12.5) Region (country) of use Language settings This data is used to optimize the browser experience for specific devices and markets, but does not contain personal information.

Does Opera Preinstall Data affect smartphone performance?
There is no definitive answer here, depending on your device model and package version. In most cases, Opera Preinstall Data has no noticeable impact on performance, as:
- 🔋 Does not consume significant CPU or RAM resources in the background.
- 📥 Does not download large amounts of data over the mobile network (usually updates weigh no more than a few times) 5-10 MB).
- 🔄 It does not start automatically when the device is turned on (unlike some system services). MIUI).
However, on weak devices (such as the Redmi 9A or POCO C31), even minor background activity can affect battery life.
To assess the real impact on your device, check the following parameters:
- Open Settings → Applications → Application Management.
- Find Opera Preinstall Data in the list.

| Action. | Possible consequences | Risk |
|---|---|---|
| Removal via ADB | The package will disappear for the current user, but will remain in the system. | Low. |
| Removal with root rights | The package will be removed completely. There may be errors when installing Opera in the future. | Medium. |
| Uninstallation without deletion | The package will stop working, but it will remain in memory. No updates will be installed. | Absent. |
| Blocking the Internet | The packet will not be able to send data, but will remain active. | Absent. |
The most common side effect is that you can’t quickly install Opera in the future: When you first start Opera or Opera Mini after you delete the packet, you’ll have to download all the data from the server, which will take more time and traffic, and there may be minor errors when you update your system applications via Google Play, but these are easily solved by rebooting the device.
