Xiaomi and Redmi smartphone owners often face reports of memory shortages or system slowdowns, prompting them to look for optimization options. One of the most popular, but also the most mythologized, methods of speeding up work is cache cleaning. Many users are afraid to press the “Clean” button for fear of losing important photos, contacts or resetting to factory settings.
In this article, we will take a closer look at what happens if you actually clean the cache, and separate the technical facts from common misconceptions: you will learn what data is deleted, how it affects the operation of the MIUI operating system, and whether it is worth doing it regularly to maintain high performance of the device.
Understanding the workings of temporary files will help you manage your smartphone memory without the risk of damaging important data. We will look at various cleanup scenarios, from a standard security application to manually deleting specific application data through the system menu.
What is cache and why is it necessary for Android system
Cache is a memory area reserved for temporary storage of frequently used data. When you run an application, such as a social network or a browser, Android stores certain interface elements, images and scripts in cache, so that when you reopen the program, it starts faster and consumes less Internet traffic.
If caching didn't exist, your phone would have to reload logos, avatars and page structure from the network or from slow internal storage, causing noticeable delays and increased battery consumption, but over time, these temporary files can grow to gigabytes, taking up useful space.
It is important to distinguish between the cache of applications and the cache of the system. The first relate to specific programs (Telegram, YouTube, Chrome), the second to the operation of the MIUI shell itself. Cleaning the system cache (through Recovery) is usually carried out in case of serious failures, whereas cleaning the cache of applications is a routine maintenance procedure.
⚠️ Caution: Clearing the cache does not delete your personal files, logins, passwords or correspondence. This action only affects temporary files that can be recreated.
💡
Regularly cleaning up the cache of heavy apps like TikTok or Instagram can free up a few gigabytes of space, but don't wait for the old CPU's instant magical acceleration.
Immediate consequences of cleaning the application cache
When you make a decision to clear a specific app’s cache through the Xiaomi settings menu, there are a number of processes that users can immediately notice, first of all, freeing up space on the internal drive, and the amount of free space depends on how much you’ve been using the program and how much media content it has saved.
But there's a downside to this: When you first run it after cleaning it, it's going to run a little slower than normal, it's going to take time to re-download the resources it needs to re-upload and create new temporary files, and that's normal behavior that doesn't indicate a breakdown.
In some cases, delogging can occur if the application used a cache to store session tokens, although modern Android security standards require that such information be stored in secure storage rather than in a regular cache.Most often you just have to re-enter your password or confirm the login via SMS.
- 🚀 Speeding up: Deleting damaged or conflicting temporary files can solve the application’s “departures” problem.
- 📉 Temporary Traffic Increase: Apps will have to re-download images and videos that were previously taken from memory.
- 🔋 Battery surge: In the first minutes after cleaning, the processor is more active, recovering data, which can briefly increase power consumption.
It’s worth noting that for some applications, such as navigators or offline maps, cache clearing can remove downloaded cards if they were stored in the cached area rather than in permanent storage. Always check where the program stores data for offline mode.
☑️ Checking before cleaning
Effect of the procedure on the MIUI system and battery
The MIUI operating shell installed on Redmi smartphones has an integrated optimization mechanism that often automatically manages temporary files.However, manual cleaning through the Security app or settings can have an additional effect if the system has not been serviced for a long time.
There is a belief that constantly cleaning the cache extends the life of the battery. It's not quite true. Yes, filled memory can slow down the recording of new data, which indirectly affects the processor, but there is no direct link between the cache volume and the battery capacity. Moreover, if you clean the cache every five minutes, the phone will constantly waste energy to restore this data, which will lead to the opposite effect.
The system cache that accumulates during updates or app installations can also be cleared.This is especially useful after a major Android or MIUI update when the old installation files are no longer needed. Deleting them is safe and frees up space, but does not affect the stability of the work, unless the files are corrupted.
⚠️ Warning: Do not use third-party cleaners with aggressive settings. They can delete necessary system files, disrupting Google services or standard Xiaomi features.
For deep cleaning, the system is sometimes recommended to use the Recovery mode, but this is a more complex procedure, requiring caution. In normal use, there are enough standard tools provided by the manufacturer.

Comparison of cache cleaning and data reset
One of the most critical things that users often confuse is the difference between clearing the cache and cleaning the data. In the Xiaomi app menu, these two buttons are often located side by side, and accidentally clicking the wrong button can lead to loss of information.
Cache cleaning, we found, is safe and only removes garbage. Data cleaning (or “Reset”) returns the application to state immediately after installation, which means removing all accounts, settings, game progress, saved dialogs, and downloaded files within the application.
Below is a table that will help you clearly understand the difference between these activities and avoid trouble.
| Parameter | Clearing the cache | Clearing of data (Discharge) | Deletion of the annex |
|---|---|---|---|
| Maintenance of logins | Preserve. | Removed | Removed |
| Disc space. | Released partially | Released almost completely | Released completely |
| Application settings | Don't change. | Dropped to the factory. | Removed |
| Risk of data loss | Minimum | Tall (no backup) | Tall (no backup) |
Use the data reset only if the application is not working properly, constantly crashes or you want to completely remove its traces before selling the phone.
💡
The main mistake users make is to confuse “Clear Cache” and “Clean Everything”; the second step is to delete and re-install the application with complete loss of local data.
How to Clean Cache on Xiaomi Redmi
Now that you know what happens if you clean the cache, let's figure out how to do it right on Xiaomi and Redmi devices. There are several ways, from simple to advanced, each with its own peculiarities.
The simplest method is to use the standard Security app, which is pre-installed on all smartphones of the brand, which automatically scans the system for junk files and suggests that they be deleted, a safe option for daily use.
To clean a specific problem application more deeply, you should use the system settings menu, which will allow you to control what is being deleted and avoid accidentally losing important data from other programs.
The sequence of actions for manual cleaning:
- 📱 Open the settings of your smartphone.
- 📂 Go to the Appendix section → All applications.
- 🔍 Find the right app in the list (for example, YouTube).
- 🗑️ Click on Warehouse and select Clear Cache.
There's also the option of mass cleaning through the storage menu. Go to Settings → About Phone → Storage. The system will show you a graph of the space you're taking and suggest you clear the garbage. You can also see which apps are taking up the most space.
Myths about cleaning cache and real effectiveness
There are many myths surrounding the topic of Android optimization that are often broadcast in popular videos and articles. Let’s break down the most common ones so you don’t waste time.
Myth number one: "Cache clearing speeds up the Internet." That's wrong. Browser cache can actually slow down page loading if it's overcrowded or corrupted, but cleaning the cache of the system or other applications doesn't affect your mobile connection or Wi-Fi speed.
Myth two: "The phone will fly like new." If your Redmi smartphone is 3-4 years old, cleaning the cache won't give it back its power. It will only make room a little bit. The brakes of old devices are related to memory wear and processor obsolescence, not temporary files.
Myth three: "Cache needs to be cleaned every day." It's a bad habit. As mentioned earlier, constant cache regeneration is loading the CPU and consuming the battery. Do this as needed, for example, when an app is behaving strangely or when there is a critical shortage of space for photos.
⚠️ Warning: If after cleaning the cache, the app stopped running or is not working properly, try clearing its data (with loss of settings) or reinstall it from Google Play.
The real efficiency of cleaning is to free up space and fix software errors associated with corrupting temporary files. The miracles in improving performance are not worth waiting, but maintaining order in the file system is useful.
