The cache on Android is temporary files that are created by applications and the system to speed up work. Over time, they accumulate, taking up gigabytes of memory, slowing down the smartphone and causing errors. But simply deleting the cache through the settings often does not solve the problem completely: hidden system files, fragmented data and garbage from deleted applications remain.
In this article you will learn how clear the cache correctly on any Android device - from budget ones Xiaomi Redmi to flagship Samsung Galaxy S24. We will analyze not only standard methods, but also hidden functions available through ADB, Recovery Mode and third-party utilities. Weโll also explain why after clearing the cache, some applications may temporarily run slower โand how to avoid it.
1. What is the cache on Android and why it needs to be cleared
Cache (from English cache โโcacheโ) is temporary files that are created by:
- ๐ฑ Applications (photos, videos, authorization data, thumbnails)
- ๐ค Android system (Dalvik cache, ART cache, update files)
- ๐ Browsers (cookies, history, cached pages)
- ๐ฎ Games (textures, levels, saves)
Without a cache, applications would have to download the same data repeatedly, wasting traffic and time. But over time, the cache grows to 5โ15 GB and begins:
- โ ๏ธ Slow down the smartphone (lags, freezes)
- ๐ Take up space on the internal storage
- ๐ Cause errors in applications (for example, YouTube video does not load)
- ๐ Increase battery consumption (background cache clearing)
โ ๏ธ Attention: Do not confuse the cache with application data! The cache can be deleted without consequences, and deleting data will lead to logging out of accounts and resetting settings.
How much cache accumulates on average?
| Device type | Cache volume for 6 months | What takes up the most |
|---|---|---|
| Budget smartphones (Redmi 12, Samsung A14) | 3โ7 GB | Social networks, instant messengers, browsers |
| Middle segment (POCO X6, Realme 11 Pro) | 7โ12 GB | Games, streaming services |
| Flagships (Galaxy S24 Ultra, Pixel 8 Pro) | 10โ20 GB | 4K video, AR applications, AI functions |
2. Standard cache clearing through Android settings
The easiest way is to use it. built-in tools. The instructions are suitable for all versions of Android from 7.0 Nougat to 15 (2026).
How to clear the cache of an individual application:
- Open
Settings โ Applications. - Select the desired application (for example, Telegram or Chrome).
- Click
Storage โ Clear cache.
How to clear the cache all applications at once:
- ๐ง Go to
Settings โ Storage. - ๐ Tap on
Others applicationsorSystem data(the name depends on the firmware). - ๐งน Select
Clear cache(may be calledFree up space).
โ ๏ธ Attention: On some devices (for example Huawei c EMUI), the option to bulk clear the cache is hidden. In this case, use the methods in the following sections.
โ๏ธ Preparing to clear the cache
3. Dalvik cache and system files
Standard methods do not delete Dalvik cache โthese are optimized Android virtual machine files that are created when installing or updating applications:
- ๐ข Fix errors. like
"The application has stopped". - ๐ Speed up work after updating Android.
- ๐ฆ Free up
500 MBโ2 GBspace.
How to clear the Dalvik cache:
- Turn off your smartphone.
- Hold
Power button + Volume up(on some models Samsung โPower + Bixby + Volume up). - In the menu
Recovery ModeselectWipe cache partition(control volume buttons, confirmation - power button). - After cleaning, reboot the device (
Reboot system now).
On devices with MIUI (for example, Xiaomi 14) the path may be different:
Recovery โ Advanced โ Wipe Dalvik Cache
What happens if you clear the Dalvik cache?
When you first boot after cleaning, Android rebuilds the cache, so the smartphone may slow down for 5-10 minutes. This is normal! Do not interrupt the process.
4. Clearing the cache via ADB (for advanced users)
If standard methods do not help, you can use Android Debug Bridge (ADB) a debugging tool that allows you to control your smartphone via a computer. This method is suitable for:
- ๐ฑ Devices with a damaged screen (when the sensor cannot be used).
- ๐ Smartphones with limited settings (for example, work phones).
- ๐ ๏ธ Removing the system application cache (for example, Google Play Services).
Instructions:
- Download ADB Tools on PC.
- Enable on your smartphone
Developer mode(tap on the build number 7 times inSettings โ About the phone). - Activate
USB debuggingin the developer settings. - Connect your smartphone to the PC and run the commands:
adb shell
pm list packages -f grep | 'cache' # Shows applications with a large cache
pm clear --user 0 com.example.app # Clears the cache for a specific package
To bulk clear the cache of all user applications:
adb shell pm trim-caches 100G
โ ๏ธ Warning: Do not clear the cache of system applications (for example com.android.systemui) unnecessarily - this can lead to interface failures.
If ADB does not recognize the device, try reinstalling the drivers or using a different USB cable (preferably the original one).
5. Automatically clearing the cache: the best applications
For It is convenient to use specialized utilities for regular cleaning. We tested 15 applications and selected the top 3:
| Application | Features | Cons |
|---|---|---|
| SD Maid |
โก Clears cache, junk, empty files folders ๐ Finds duplicate photos and videos ๐ Shows detailed statistics |
Paid version is needed for deep cleaning |
| CCleaner |
๐งน Removes cache, browser history, temporary files ๐ Optimizes autoloading ๐ฑ Easy interface |
Advertising in the free version |
| Files by Google |
๐๏ธ Built into Android on many devices ๐ Removes not only cache, but also unnecessary files ๐ Scans memory for garbage |
Does not clear Dalvik cache |
How to use SD Maid:
- Download the application from Google Play.
- Start scanning (
CorpseFinderlooks for garbage from deleted applications). - Select
Cachein the sectionCleaner. - Click
Run nowand confirm cleaning.
Cache clearing applications do not replace manual methods! They do not remove the system cache and Dalvik, so use them as an add-on.
6. Clearing browser cache: Chrome, Firefox, Samsung Internet
Browsers are the main cache โdrivesโ. For example, Google Chrome can take up to 1โ3 GB temporary files, cookies and site data. Cleaning helps:
- ๐ Remove traces of visited sites.
- ๐ Speed up page loading.
- ๐ก๏ธ Correct type errors
ERR_CACHE_MISS.
How to clear the cache in Google Chrome:
- Open the browser and tap โฎ (
Menu). - Select
History โ Clear data. - Set the checkboxes:
- ๐๏ธ
Cookies and site data - ๐ผ๏ธ
Cached images and files
- ๐๏ธ
All time) and click Delete data.For Samsung Internet i Firefox the path is similar, but with nuances:
- ๐ฆ In Firefox there is an option
Clear on exit(in the privacy settings). - ๐ฑ In Samsung Internet you can clear the cache separately for each site in
Settings โ Personal data.
7. When clearing the cache does not help: alternatives. solutions
If after clearing the cache the smartphone still slows down, the problem may be deeper:
- ๐งฉ Memory fragmentation: even after clearing the cache, files are scattered throughout the drive. Solution -
storage optimization(in the memory settings). - ๐ฆ Viruses or malware: some applications restore the cache immediately after clearing. Check the device through Malwarebytes.
- ๐ Outdated firmware: on Android
9 and belowthe cache is managed less efficiently. - ๐พ Problems with the drive: if the free space โdisappearsโ by itself, check the health of the memory through
ADB:adb shell df -h
Extreme method - reset to factory settings. It deletes all data, including the cache, but should only be used if:
- ๐ The smartphone has become unbearably slow.
- ๐ง Other methods did not help.
- ๐ฆ You have a backup copy.
โ ๏ธ Attention: On some devices (for example, OnePlus s OxygenOS), resetting to factory settings does not clears the Dalvik cache. After resetting, go toRecoveryand performWipe cache partitionmanually.
FAQ: Frequently asked questions about clearing the cache on Android
โ Do I need to clear the cache regularly?
No, it is enough to do this once every 1-3 months or when lags appear. Frequently clearing the cache can, on the contrary slow down, since applications will have to rebuild temporary files.
โ Why do some applications work after clearing the cache? slower?
This is normal! Applications need time to restore optimized files. For example, Instagram or TikTok may take longer to load content in the first 5-10 minutes after cleaning.
โ Is it possible to clear the cache without losing data?
Yes, clearing the cache does not affect personal files (photos, videos, messages). The exception is the cache of some messengers (for example, WhatsApp), where media files are temporarily stored. They will disappear, but the originals will remain in chats.
โ How to clear the cache on Android without access to the settings (for example, if you have a phone) blocked)?
There are 3 ways:
- Connect via
ADB(pre-activation of debugging is required). - Boot into
Recovery Modeand selectWipe cache partition. - Use Find My Device from Google for a remote reset (but this will delete all data!).
โ Is it true that clearing the cache saves battery power?
Indirectly, yes, a full cache forces the system to access the drive more often. consumes energy. But the effect is minimal: at best, you will gain 5-15 minutes work from one charge.
