Installing CCleaner on Xiaomi Redmi smartphones is a controversial topic, on the one hand, users want to free up memory and speed up the device, on the other hand, risk disrupting the stability of the device. MIUI, Unlike PCs, where the utility has long become the standard, on Android (especially on Xiaomi firmware), its behavior is harder to predict.

Many owners of Redmi Note 12, Redmi 10 or POCO X5 The question is, “Do you need to use CCleaner at all?” MIUI Do you have any built-in cleaning tools? "" The answer is not as obvious as it seems. The fact that Xiaomi actively blocks the background activity of third-party “optimizers”, and aggressive cleaning of the cache can lead to the reboot of these applications at the next launch, which will only increase traffic consumption and battery power. Next, we will analyze how CCleaner works on Redmi, which features are really useful, and which ones are better to abandon.

Spoiler: 90% of the time built-in tools MIUI They can clean up as well as, and often better than, third-party utilities, but there are nuances, like deleting residual files after uninstalling applications or deep cleaning of Dalvik cache, which CCleaner does more efficiently. The main thing is to understand what you are cleaning and what consequences it can lead to.

What is CCleaner and why is it needed on Xiaomi Redmi?

CCleaner is a system cleanup utility originally developed for Windows, butter adapted for Android. On Xiaomi Redmi smartphones, it promises:

• 🧹 Delete unnecessary files (cache, temporary data, application residues)
• 📱 Optimizing memory and increasing free space
• 🔋 Extending battery life by stopping background processes
• 🛡️ Privacy protection (clearing the history of calls, messages, browser)

However, in practice MIUI (13-14 already contains similar features in the Settings section → Memory or Security → Moreover, Xiaomi actively restricts the capabilities of third-party optimizers through the mechanism. MIUI Optimizer, which can block CCleaner's background activity, reducing its effectiveness to zero.

Another problem is aggressive cache cleaning, and many Redmi users complain that after using CCleaner, apps take longer to load and games slow down, because the utility removes the Dalvik cache (optimized data for quick program launches), forcing the system to reassemble it again.

How CCleaner interacts with MIUI: technical

Firmware MIUI It is based on Android, but has a number of unique features that affect the operation of CCleaner:

• 🛠️ Conflict with MIUI Optimizer: The com.miui.optimizer system process can reverse changes made by CCleaner if it considers them to be “unsafe».

Interesting fact: in the old versions MIUI (before 12.5) CCleaner could delete files from folder /data/local/tmp, In the new versions, Xiaomi has closed this patch, but the risk of data corruption from careless cleaning remains.

If you still decide to use CCleaner on Redmi, here’s what happens when you run the utility:

1. Scanning the file system for “junk” (cache, logs, residues) APK).
2. Attempting to delete temporary files from folders /cache, /data/data/*/cache.
3. Clear your browser history, calls and messages (if allowed in the settings).
4. Stopping background processes (may conflict with the MIUI Battery Saver).

Risks of using CCleaner on Xiaomi Redmi

Another trap is a false sense of security, and many users, after cleaning up the CCleaner, see more free memory, but they don't notice it eats away again after a couple of days. MIUI actively caches data to speed up work, and their deletion only temporarily frees up space.

For advanced users, alternative utilities are suitable:

• 🛠️ SD Maid is a more flexible analogue of CCleaner with root rights support (but requires caution!).
