Modern smartphones based on Android have impressive capabilities, but over time they may begin to work slower. One of the main reasons for slow performance and application errors is the accumulation of temporary files. This data, called cache and cookies, is necessary for fast loading of content, but its excess can lead to interface failures and excessive consumption of internal memory.
Many users mistakenly believe that deleting these files will erase important personal data such as photos or contacts. In fact, clearing the cache is a safe procedure that only resets temporary settings and speeds up the device. In this article, we will analyze in detail how these concepts differ and provide step-by-step guide for different versions of the operating system.
You will learn how to find hidden settings in the menu of your gadget, which tools should be used for browsers, and also when user intervention is really necessary. Understanding the mechanism of how memory works will help you maintain your smartphone in perfect technical condition without contacting service centers.
What is the difference between cache and cookies
Before proceeding with deletion, it is important to clearly understand the difference between these two types of data. Cache is a storage of temporary files, such as images, scripts and website design elements that are saved on the device after the first visit to the resource. This allows the browser or application not to re-download the same data from the Internet, which significantly saves traffic and speeds up the display of pages.
Unlike cache, cookies (cookies) are small text records that sites save on your device to identify the user. They store information about your preferences, data for automatically logging into your accounts, the contents of your online store cart, and your activity history. Deleting cookies will mean that you will have to re-enter logins and passwords on most of the resources you visit.
This data is stored in different sections of memory, but both types of files take up space in the internal storage. Over time, the cache size can reach several gigabytes, especially if you actively use social networks or streaming services. Excessive outdated or corrupted cookies can cause web pages to display incorrectly or login problems.
Regular cleaning can help free up space and eliminate software conflicts. However, you should not do this too often, since constantly downloading the same elements from the server can, on the contrary, slow down the work in conditions of a weak Internet connection.
⚠️ Attention: Clearing cookies will lead to logging out of all accounts in the browser. Make sure you remember passwords for important services before starting the procedure.
Preparing the device for the cleaning procedure
Before you begin mass deletion of temporary data, it is recommended to perform several preparatory steps. This will help you avoid unexpected situations such as losing unsaved drafts or resetting critical application settings. First, make sure that you have access to the Internet, as after clearing cookies, some services will require resynchronization.
It is also worth checking the presence of important data in the browser. If you use the browser's own password manager and have not synchronized it with your cloud account Google, export your saved logins in advance. In some cases, a damaged cache can block the operation of certain functions, so a complete clear is sometimes the only way to solve the problem.
- 🔋 Make sure that the battery charge is at least 30% so that the device does not turn off during system operations.
- ☁️ Check the synchronization activity with your Google account to save contacts and notes.
- 📱 Close all applications running in the background through the multitasking menu.
If you plan to clear data from specific applications, such as instant messengers, make backup copies of chats within the apps themselves. For example, WhatsApp or Telegram has built-in functions for creating backups, which should not be neglected. Preparation takes only a couple of minutes, but saves you from many hours of restoring access to services.
Before global cleaning, take screenshots of important settings in the browser or the list of installed extensions so that you don’t forget anything when restoring your working environment.
Clearing cache and cookies in the Google Chrome browser
The most A common cleaning scenario is related to the browser Google Chromewhich is installed on most devices by default. The settings interface may differ slightly depending on the version of the manufacturer's shell, but the logic of actions remains the same. To get started, launch the browser and click on the three vertical dots in the upper right corner of the screen.
In the menu that opens, select Settings, then scroll down the list to the section Privacy and security. Here you will need to find the option Clear history or Deleting browsing data. The system will prompt you to select a time range: it is recommended to set the value All the timeto delete all accumulated garbage.
A window will open with checkboxes where you need to check items Cookies and site data, as well as Images and other files saved in the cache. You don't have to delete your browsing history if you want to keep a list of visited resources for yourself. After selecting the parameters, click the button Delete data and confirm the action in the system dialog.
| Type data | What is deleted | Consequences |
|---|---|---|
| History | List of visited URLs | Disappears from the address bar when entered |
| Cookie | Session data and inputs | You need to log in to the sites again |
| Cache | Pictures and scripts | Sites will take a little longer to load the first time |
| Passwords | Saved access keys | Loss of automatic password entry |
The process may take from a few seconds to a couple of minutes, depending on the amount of accumulated information. Once completed, the browser will automatically reload active tabs. If you use other browsers, for example Firefox or Opera, the algorithm of actions will be similar, although the names of menu items may vary.
☑️ Check cleaning in the browser
Delete cache of system applications through settings
In addition to browsers, each installed application on your smartphone creates its own cache to speed up work. Over time, these files can take up a significant portion of memory, especially for heavy apps like social networks or navigators. Cleaning is carried out through the main menu of the device settings, the path to which usually looks like Settings → Applications.
In the list of all apps, select the application that consumes a lot of space or is unstable. Click on it to open the app information page. Here you will see a button Storage or immediately memory management options. The system will show two options: Clear cache and Clear data.
Choose exactly Clear cacheif you just want to free up space and eliminate possible glitches. This operation is safe and does not affect your personal settings within the application. The button Clear data (or Reset) returns the app to the state immediately after installation, deleting all accounts, saves and configurations.
⚠️ Attention: Do not click the "Clear data" button for instant messengers without first backing up, otherwise you may lose your correspondence.
For users who want to clear the cache of all apps at once, there is a hidden function in some versions of Android. It can be activated in the developer menu, but standard means of mass cleaning of all applications are not provided at once. Therefore, the optimal solution is to selectively clean the most "gluttonous" applications, such as YouTube, Instagram or TikTok.
How to find the heaviest applications?
In the "Storage" menu in the phone settings there is often a section "Other applications", sorted by size. There you can immediately see which apps take up the most space due to the cache.
Using the Google Files function for cleaning
The company Google has developed a special application Files by Googlewhich is pre-installed on many modern smartphones and serves as an excellent tool for memory management. This utility automatically analyzes the contents of your storage and offers to remove unnecessary files, including duplicates, old screenshots and, of course, application junk.
Launch the application and go to the tab Cleaning in the lower left corner. The system will offer several categories for deletion. We are interested in the section Unused applications or Temporary files. The smart cleaning algorithm safely identifies files that can be deleted without harm to the system.
Click the button Clean next to the one you need category. The application will ask for confirmation and then delete the selected data. This is one of the fastest and safest ways to maintain order in your memory, especially for users who do not want to dive deeply into the technical settings of each app.
- 🗑️ The application automatically finds duplicate photos and offers to delete unnecessary copies.
- 📂 You can easily find and delete downloaded files that you no longer use look.
- 🚀 The free up space function works faster than manually sorting through folders.
Regular use of this tool helps prevent memory overflow, which is often the cause of interface slowdowns. Unlike third-party “cleaners” from the Play Market store, the official application from Google does not contain intrusive advertising and does not collect unnecessary data about the user.
Using the built-in Google Files tool is the safest method of mass cleaning of garbage for ordinary users, which does not require deep technical knowledge.
Radical measures: resetting settings and Recovery mode
In situations where the smartphone is extremely unstable, constantly produces errors, or the cache is not cleared by standard methods, more radical measures may be required. One of these methods is to enter the Recoverymode. This mode allows you to clear the cache partition of the entire system (Dalvik Cache), which can solve problems after an unsuccessful firmware update.
To enter this mode, you need to turn off the smartphone, and then hold down a certain key combination when turning it on. Most often this is the power button along with the volume up button. On different models (Samsung, Xiaomi, Poco), the combinations may differ, so it is worth checking the instructions for a specific model on the Internet.
Volume Up + Power Button (hold until the logo appears)In the menu that appears, navigation is carried out using the volume buttons, and selection is made using the power button. Find the item Wipe Cache Partition and confirm the action. It is important not to confuse this item with Wipe Data/Factory Reset, which will completely delete all your personal files and return the phone to its factory state.
⚠️ Attention: In Recovery mode, the touch screen does not work. Be extremely careful when selecting menu items so as not to accidentally delete all data from the phone.
This method is recommended only for experienced users or in extreme cases when other methods have not helped. After clearing the cache partition, select Reboot System Now to reboot the device. The first boot may take longer than usual as the system will re-create optimized files.
What is Dalvik Cache?
This is a special cache that stores optimized application files for your phone's processor. Clearing it forces the system to re-optimize all applications the next time you start it.
Frequently asked questions (FAQ)
Will clearing the cache delete my photos and contacts?
No, clearing the cache only affects temporary technical files of applications and browsers. Your personal media files, contacts, messages and installed apps remain completely safe. Only data that can be downloaded from the Internet is deleted.
How often should you clear the cache on Android?
Modern versions of Android effectively manage memory on their own. Manual cleaning should only be done if problems arise with a specific application or if free space is critically low. Preventative cleaning once every couple of months is quite sufficient.
Why does the cache quickly fill up again after cleaning?
This is normal system behavior. Applications create a cache to run quickly. As soon as you open a app or website, it starts saving temporary data again. Endless struggle with this process does not make sense, unless the cache grows abnormally quickly due to an error in the application code.
Is it possible to automate the cleaning process?
Yes, for this you can use the built-in "Cleaning" function in the Google Files application or configure automatic deletion of history in the settings of the Chrome browser itself (section "Personal data"). Third-party cleaner applications are often less effective and may contain advertising.
Does clearing cookies affect the security of your accounts?
On the contrary, regularly clearing cookies increases security because it removes session data, which could theoretically be intercepted by malware. However, this requires frequent re-entering of passwords, so it is important to use strong authentication methods.
