How to Clean Cache on Xiaomi Mi A2: The Complete Guide

The Android One lineup, which includes the Xiaomi Mi A2, is famous for its cleanliness and performance, but over time even they start to slow down. The main reason for the decline in performance and lack of free space is often accumulated app cache and system temporary files. Many users mistakenly believe that to solve the problem you need to delete photos or remove rarely used programs, but the key lies in the correct cleaning of hidden memory parts.

Unlike the MIUI shell, which is standard for most of the brand’s devices, the Mi A2 has a clean version of Android, which changes the algorithm for how to service the device. Understanding where temporary data is stored and how to safely delete it without losing personal information is a critical skill for the owner of this gadget. It is important to know that cleaning the cache does not delete your personal photos, contacts or correspondence, unless you confuse the “Cache” and “Erase data” buttons.

In this article, we will take a look at all the memory optimization methods available, from built-in system tools to the use of engineering menus, learn to distinguish between types of junk files and understand why regular maintenance of a device prolongs its life. Consider safe ways to speed up the Xiaomi Mi A2 without installing dubious software-cliners.

What is cache and why clean it on Android

Cache is a region in the device’s memory that is designed to temporarily store data that applications often use to speed up their work. When you open a favorite website in a browser or launch a social network, the system stores interface elements, pictures and scripts in local storage, which allows Android to load pages faster when you re-access, without downloading information from the Internet again.

However, over time, these temporary files can grow to giant sizes, taking up precious gigabytes of internal memory. In addition, old or damaged cache files can cause conflicts in the operation of programs, leading to freezes, spontaneous closure of applications and a decrease in the overall response rate of the interface.

It is worth noting that the cache is different: system and user cache, the system cache is used by the operating system itself to correctly work the background processes. The user cache belongs to specific applications, such as YouTube, Instagram or navigators. The accumulation of garbage in these sections is a natural process of operation, requiring periodic user intervention to prevent failures.

Clearing the cache of individual applications through settings

The safest and most recommended way to free up space is to delete temporary files for specific, “heavy” applications. On the Xiaomi Mi A2 with pure Android, this process is done through a standard settings menu, which ensures that there are no errors and accidental deletions of the necessary information.

To start, you need to go to the program management menu. Click on the settings icon (cogs) and find the Applications and Notifications section. From the list that opens, select Application Information or simply scroll down to the program you want, and here you will see detailed statistics on how memory is used by a particular application.

Inside the app menu, find the Storage and Cache (or simply "Storage") section. The system will show two values: data size and cache size. We're interested in the second button. By clicking Clear Cache, you'll only delete temporary files without touching your logins, passwords and settings. This is a secure operation that you can do regularly.

• 📱 Open Settings and go to the Applications section.
• 🔍 Find a “heavy” app (like YouTube or Telegram) in the list).
• 🗑️ Press Storage and select the Clear Cache button.
• ✅ Repeat the procedure for 3-5 most used programs.

Use of the built-in utility Files by Google

Since the Xiaomi Mi A2 runs on Android One, Files by Google is a standard file management tool, which is not just a file manager, but a smart system that analyzes the contents of memory and suggests removing duplicates, unused applications and, of course, garbage.

Launch Files and go to the Cleanup tab (usually the broom icon) and the system automatically scans the device and prompts you to delete "Unnecessary Files." This section hides the remnants of deleted programs, temporary files and a cache that can be safely removed, a process that is fully automated and takes seconds.

In addition, in the Big Files section, you can find large videos or archives that you may have forgotten about. Deleting such objects often frees up more space than cleaning the cache. The utility also knows how to find screenshots older than 30 days and offers to delete them, which is very convenient for maintaining order in the gallery.

It is important to understand the difference between the suggestion to delete "big files" and "cache." Large files are your personal data (video, documents), and cache is technical garbage. Be careful when choosing categories for cleaning, so as not to accidentally delete an important film or document.

💡

Use the Offline Graphs feature in Files by Google to find and remove saved maps and music that take up a lot of space but are rarely used.

Cleaning the system cache through Recovery Mode

If the smartphone is unstable, the interface is buggy, or strange errors occur after the system update, it may be necessary to clean the Cache Partition. This is the hidden partition where the operating system puts its temporary files. Cleaning this partition does not affect the user’s personal data, but requires logging into recovery mode.

To enter recovery mode on the Mi A2, turn off the phone completely. Then press the volume down and power button at the same time. Hold them until the Android logo or Bootloader menu appears. If you have a menu with a rabbit, use the volume buttons to navigate to the Recovery Mode and confirm the choice of the power button.

In the Recovery menu (where the volume buttons are controlled and the power button is selected), find the Wipe cache partition. Don't confuse it with Wipe data/factory reset! The second option will completely destroy all your data. Once you choose to clear the cache, the system will confirm the action, and the process will take a few seconds. Once completed, select Reboot system now.

⚠️ Attention: Be extremely careful on the Recovery menu. data/factory reset completely wipes the phone back to factory condition.

Removing browser cache and messengers

Browsers and instant messengers deserve special attention, as they tend to grow databases quickly. For example, Telegram and WhatsApp store all the photos and videos you viewed in cache, even if you did not download them explicitly, while browsers store copies of all the pages visited to speed up loading.

In messengers, it is better to use built-in cleaning tools, not system ones. Go to the Settings of the application itself (for example, Telegram), select Data and memory → Memory Use. You can clear the cache with a single click, and also configure a reset of media files (for example, store photos for 3 days, and video for 1 day).

For browsers (Chrome, Firefox), the path is through the general Android settings: Settings → Apps → Chrome → Storage → Place Management → Clean everything. This action will unlog you on the sites, but free up a significant amount of space. Regular cleaning of these applications is the key to fast Internet on the phone.

• 📸 In Telegram, set up autodelete the cache: Settings → Data and memory.
• 🌐 In Chrome, use the History function. → Clear the history for the selection of the period.
• 💬 On WhatsApp, go to Warehouse in chat settings for volume analysis.

💡

Built-in cleaners inside instant messenger applications work more efficiently and securely than system data deletion, as they do not reset authorization.

Frequent questions and problems with cleaning

Users often encounter incomprehensible situations while maintaining their Xiaomi Mi A2. For example, after cleaning the cache, the application can run a little longer than usual on the first start - this is normal, since it re-forms temporary files.

The use of aggressive Play Market “cleaners” on Android One often does more harm than good, can force system processes to close, resulting in increased battery consumption when they are restarted.

⚠️ Note: If after cleaning the cache, the application stopped saving passwords or settings, you may have accidentally chosen "Erase data" instead of "Erase cache.
