Smartphones running an operating system Android 11 are equipped with complex memory management algorithms that automatically regulate the volume of temporary files. However, over time, users experience slowdowns in the interface or a lack of free space to install new apps. Temporary data accumulated by the browser, instant messengers and system services can take up gigabytes of valuable space in internal storage.
The procedure for deleting these files does not require obtaining root access or installing third-party software, since the system provides built-in tools for these purposes. Proper cache management allows you not only to free up space, but also to eliminate application errors caused by corruption of temporary data. In this guide, we will analyze in detail all cleaning methods - from basic settings to advanced engineering menus.
The concept of cache in the Android architecture
The cache is an area in the device memory designed for quick access to frequently used data. When you open a web page or launch a heavy game, the system saves some information so that the next time you access it it does not have to download it again from the network or disk. This significantly speeds up work user interface and reduces the load on the processor.
However, uncontrolled cache growth can lead to the opposite effect. Files may become outdated, conflict with new versions of applications, or simply take up space needed for current tasks. It is important to distinguish between application cachewhich can be cleared selectively, and the system cache, the removal of which requires a more careful approach.
In modern versions of the OS, Google has implemented an adaptive memory management mechanism that itself tries to delete old files. But this mechanism does not always work effectively, especially if the user actively uses social networks with a large number of media files. Manual cleaning in such cases becomes a necessity.
Browser cache and application cache are different storages. Clearing one does not affect the other, so to completely free up space, you need to check both partitions.
Clearing the cache of individual applications
The safest and most common method is to delete temporary files for a specific app that takes up too much space. This approach does not affect the user’s personal data, such as logins, passwords or correspondence, since it only affects a temporary buffer.
To complete the procedure, you must go to the device settings section. Navigation may differ slightly depending on the manufacturer's shell (MIUI, OneUI, ColorOS), but the logic remains the same. You will need to find the control point for all installed apps.
Select the desired application from the list, for example, YouTube or Telegram. Inside the application menu, you will see a clear button. Clicking on it will instantly free up space occupied by temporary video thumbnails, loaded avatars and other lightweight data.

Please note that the button Clear data works differently: it resets the application to its factory state, deleting all your settings and accounts inside it. Use this function only in extreme cases, when the app does not work correctly and reinstallation does not help.
☑️ Check before cleaning
Global cleaning through the storage menu
Operating system Android 11 provides a convenient dashboard for memory management, where you can see the overall picture of disk capacity. This tool automatically categorizes files and offers to remove unnecessary junk, including the cache of all installed apps at once.
In this section you will find detailed statistics by category: images, video, audio, etc. The system intelligently highlights files that have not been used for a long time, suggesting they should be deleted. This is a broader approach than spot cleaning, and is suitable for quickly preparing the device before important events that require a lot of free space.
⚠️ Warning: The "Clear All" function in the storage menu may delete the cache of all applications at once. This will cause the apps to download data again the next time you launch them, which may temporarily increase mobile data consumption and battery life.
To access this tool, use the path Settings → Storage. Here the system will show the free space and suggest optimization. If you click on the "Other applications" category, you will see a list of apps sorted by the space they occupy.
Resetting the DNS cache to solve network problems
Sometimes problems with the Internet are not related to the provider, and with outdated entries in the smartphone’s DNS cache. This may manifest itself in some sites not opening, and others loading with errors, although Wi-Fi or mobile network is working properly.
There is no direct "Reset DNS" button in the regular menu, but this operation can be performed through the developer menu or using private DNS. Changing the DNS settings forces the system to recreate the mapping table between domain names and IP addresses. Android 11 There is no direct "Reset DNS" button in the regular menu, but this operation can be performed through the developer menu or using private DNS. Changing the DNS settings forces the system to recreate the table of correspondence between domain names and IP addresses.
The most effective way is to temporarily disable private DNS. Go to the network settings, find the item Private DNS and switch it to Auto or Disabledmode, and then return it back. This action initiates an update of network parameters.
For deeper cleaning, you can use Airplane mode. Enabling and disabling airplane mode restarts all network interfaces, which often helps to reset frozen connections and clear the network buffer without complex manipulations.
How to enter the developer menu
To access advanced network settings, you need to activate the mode developer. Go to "About phone" and click on "Build number" 7 times. After this, a new section “For Developers” will appear in the settings menu, where you can find the option to reset network settings.
Using Recovery Mode
If the smartphone is extremely unstable, freezes when loading or constantly produces system errors, you may need to clear the partition cache partition. This is a special area in memory, different from the user storage, where temporary system update files are stored.
This procedure is safe for your personal data: photos, contacts and applications will remain in place. Only service logs and temporary update files that may have been damaged during the previous firmware installation are deleted.
To enter recovery mode, you must turn off the device and use the key combination. On most devices, this is a combination of the power button and the volume down button. On some models Samsung you may need to connect a USB cable to the computer.
⚠️ Attention: In the Recovery menu, control is carried out only by the volume buttons (up/down) and the power button (select). The touch screen does not work in this mode. Be extremely careful not to select the "Wipe data/factory reset" item, which will delete all your data.
After entering the menu, find the item Wipe cache partition. Confirm the action with the Power button. The process will take a few seconds, after which you need to select the item Reboot system now to reboot the smartphone in normal mode.
| Action | Impact on data | Difficulty | When to apply |
|---|---|---|---|
| Clear application cache | Safe, deletes temporary files only | Low | Daily optimization |
| Clear application data | Deletes logins, settings and history inside the application | Medium | If the app malfunctions |
| Wipe cache partition | Safe for the user, removes system junk | High | After updating the system or failures |
| Factory Reset | Complete deletion of all data from the phone | Critical | Before sale or in case of viruses |
Automating the process using ADB
For advanced users with access to a computer, it is possible to clear the cache through the debug bridge Android Debug Bridge (ADB). This method allows you to delete the package cache without having to go into the menu of each application manually.
You must first activate USB debugging in the developer menu on your smartphone and install ADB drivers on your computer. After connecting the device, run the command in the terminal or command line.
adb shell pm trim-cachesThis command will ask the system to free up space by deleting cached files. You can also use a more aggressive command for a specific package if you know its name, but the standard command trim-caches is the most universal and safe for Android 11.
Using ADB commands is the fastest way to clear the cache of all applications at once, but requires a PC and basic command line skills.
⚠️ Attention: Menu interfaces and item names may differ depending on the model of your smartphone and the version of the user shell. If you do not find the item described, check the manufacturer's official instructions or look for a similar name in the settings.
Frequently asked questions (FAQ)
Will my WhatsApp correspondence be deleted when clearing the cache?
No, clearing the cache (Clear Cache) affects only temporary files, such as image thumbnails or temporary logs. Your correspondence, media files and account settings will be saved. However, clearing “Data” (Clear Data) will delete everything, including message history, if there is no backup.
How often should you clear the cache on Android 11?
There is no special frequency. Only do this when you notice a lack of space or strange behavior of applications. Modern systems manage memory efficiently themselves, and frequent manual clearing can even slow things down, since the phone will have to rebuild the cache.
Why does the cache quickly fill up again after clearing?
This is normal behavior of the operating system. Applications create a cache to speed up their work. If you immediately start actively using the browser or social networks, they will again load pictures and scripts into temporary memory.
Is it possible to delete the Android folder completely?
It is strictly not recommended to delete the entire folder Android manually through a file manager. This may lead to loss of application data, factory resets, and system instability. Use only standard cleaning tools through the settings.
Does clearing the cache affect the speed of the phone?
In the short term - yes, if the cache was full or damaged, the phone may start working faster. However, immediately after cleaning, you may notice a temporary slowdown, as the system and applications will take time to re-create the necessary temporary files.
