You have probably noticed that over time your smartphone begins to work slower, and the scary message “Memory full” appears in the storage settings. Often the culprit in this process is the browser you use every day. In particular, Yandex Browser on Android it tends to quickly grow in the occupied space, which raises natural questions among users.
The reasons for this behavior lie not in development errors, but in the specifics of the work of a modern web browser. It stores gigabytes of temporary files to speed up page loading, stores copies of sites for offline access, and stores service data. Understanding exactly how this volume is formed will help you competently manage the space on your device without losing important bookmarks and passwords.
In this article, we will analyze in detail the data storage architecture in Yandex Browser, identify hidden memory hogs and offer step-by-step guide for safe cleaning. You will learn which files can be deleted without regret, and which are better left untouched so as not to disrupt the operation of your favorite web services.
Structure of the application's internal storage
When you install any app on Android, the system allocates a certain section of memory for it. In the case of a browser, this section is divided into several logical parts: the installation file itself (APK), user data and cache. It is the last two categories that usually cause the greatest increase in occupied space.
Application data include your browsing history, saved passwords, synchronization settings, bookmarks and cookies. This volume grows linearly and relatively slowly, since text information does not take up much space. However, if you actively use built-in Yandex services, such as Mail or Drive, the amount of data may increase due to local copies of letters or documents.
The largest share is occupied by cache. These are temporary files: images from websites, scripts, CSS styles, and even fragments of video streams. The browser saves them so that when you visit the resource again, it does not have to download the content again from the Internet. Over time, this folder can grow to several gigabytes, especially if you often watch videos or visit “heavy” media portals.
⚠️ Attention: When you completely clear the application data (not just the cache), you will lose all saved passwords and settings if synchronization with your account is not enabled Yandex.
It is also worth considering update files. The browser periodically downloads new versions of the engine and security components. Sometimes old versions of files are not deleted instantly, creating a temporary duplicate volume during the update process.
The role of cache and temporary files in memory consumption
Cache is the main tool for optimizing web speed, but its aggressive accumulation often runs counter to the limited resources of mobile devices. Yandex Browser by default it is configured for maximum performance, so it strives to preserve as many page elements as possible in local storage.
Particular attention should be paid to the video content cache. If you watch videos on YouTube or other platforms through a browser, parts of the video files are saved to disk. Even after closing the tab, these fragments can remain in memory for days until the system decides to overwrite them with new data. This is one of the main reasons why memory fills up so quickly after watching movies.
- 🖼️ Graphics cache: images, banners, icons of sites you visited.
- 🎬 Media cache: buffered parts of audio and video streams, often occupying hundreds of megabytes.
- 📜 Script cache: site app code necessary for the operation of interactive elements and advertising.
The user can manually control the cache size through the browser settings. However, Android's automatic cleaning mechanisms don't always work on time, especially if you have a lot of other apps installed competing for space. As a result, the browser cache can take up to 70-80% of the total volume allocated for the application.
If you often watch videos in the browser, try to use the official application of the service (for example, YouTube), as it better manages its cache and allows you to upload data to the cloud.
It is important to distinguish between the concepts of “Clear cache” and “Clear data”. The first operation is safe and only resets temporary files, causing sites to take a little longer to load on the first visit. The second operation returns the browser to the “as after installation” state, deleting all your personal settings and logins.
The influence of add-ons, themes and extensions
Modern browsers have turned into full-fledged platforms that support the installation of extensions and changes in visual design. Each installed add-on is additional code, resources and, often, its own database, which is stored in the phone’s memory.
Extensions to block ads, password managers or screenshot tools require constant access to tab data. They can create their own logs and cache. For example, an ad blocker stores domain databases that are updated regularly, and visual extensions can load heavy graphic elements for the interface.
Themes also contribute. While theme files themselves are typically small, the process of applying them and preloading graphics assets can create temporary files. If you often change themes or use “live” wallpaper inside the browser, the consumption of RAM and permanent memory increases.
| Add-on type | Approximate data weight | Impact on speed | Recommendation |
|---|---|---|---|
| Ad blocker | 50–150 MB | Medium (traffic filtering) | Leave, saves traffic |
| Visual themes | 10–30 MB | Low | Delete unused |
| Download managers | 20–50 MB | Low | Check folder downloads |
| News widgets | 100–300 MB | High (constant background) | Disable on weak devices |
Some extensions work in the background even when the browser closed. This not only drains battery power, but also holds certain files in RAM, preventing the system from completely freeing up resources. Regular audit of installed add-ons helps reduce the load on the device.
Accumulation of history, bookmarks and site data
In addition to technical files, the browser carefully stores the history of your digital life. Browsing records, autofill forms, and cookies make up a significant portion of user data. Over time, this database becomes huge, especially if you do not use incognito mode.
Cookies - these are small text files that sites use to identify the user. They store data about sessions, preferences and shopping cart. Although one cookie is small, there are thousands of them. Browsers store them for quite a long time so that you do not have to log in to each site again every time you launch it.
Browsing history is indexed for quick search. When you start typing into the address bar, the browser accesses this database. The longer the history, the more space it takes up and the more processor resources are spent on processing it with each search.
⚠️ Attention: Deleting cookies will lead to logging out of your accounts on most sites. You will have to enter your passwords again.
The Tableau function in Yandex Browser also stores data about frequently visited sites, including their icons and page previews. These thumbnails are saved as images and over time can take up a noticeable amount of space if you visit many different resources.
Downloaded files and offline mode
One of the most common reasons for lack of space is simple user forgetfulness regarding downloaded files. When you download a document, picture or apk file through the browser, it is saved by default to a folder Download in the internal memory. The browser does not automatically delete them after viewing.
In addition, many modern sites support technology PWA (Progressive Web Apps) or have built-in offline access functions. Yandex Browser can cache entire pages or articles so you can read them without the Internet. This data is stored in a special storage section and is not always visible to the user as regular files.
The built-in “Turbo” or traffic saving mode also creates temporary files of compressed content. Although this saves the Internet, intermediate buffers are created on the disk. If the function does not work correctly or files are not cleared after the session, they may accumulate.
- 📂 Downloads folder: check the directory
/storage/emulated/0/Download/Yandexfor old files. - 💾 Offline maps: if you used Yandex maps inside the browser, their cache may be voluminous.
- 📑 Saved pages: Files saved through the “Save As” menu remain on the disk indefinitely.
It is recommended to regularly check the downloads section inside the browser. Often, duplicate files or documents accumulate there that have already been sent to instant messengers and are no longer needed in their original form in the phone’s memory.

Effective methods of cleaning and optimization
To regain free space on the device, you need to act comprehensively. Simply deleting the cache may not be enough if the problem is due to accumulated downloads or heavy extensions. Below are the most effective optimization methods.
The first step is to use the built-in cleaning tools. In the Yandex Browser settings there is a “Confidentiality” section where you can choose which data you want to delete. Here it is important not to just click the “Clear all” button, but to select specific categories, such as “Cache” and “Files saved for offline access,” while leaving passwords and history if they are important to you.
The second method is manual cleaning through the Android settings. Go to Settings → Applications → Yandex → Storage. Here you will see a clear separation between application size and data size. The “Clear cache” button here is safe and effective for quickly freeing up space.
The way to manually check files (via the file manager):
/storage/emulated/0/Android/data/com.yandex.browser/cache/
The third method is radical, but effective. If the browser is unstable and takes up an abnormally large amount of space, you can try uninstalling updates to the factory version, and then updating it again from Google Play. This resets all internal file indexing errors.
⚠️ Attention: The Android settings interface may vary depending on the phone model (Samsung, Xiaomi, Pixel). The names of menu items may vary.
What to do if space becomes free, but quickly fills up again?
This may indicate a malicious script running on a frequently visited site or a malfunction of the application itself. Try going into incognito mode and checking your memory consumption there. If the problem disappears, one of your accounts or extensions is to blame.
Do not forget about the “Turbo” function and the economy mode. Sometimes disabling them helps reduce the volume of temporary files created if you use a stable and fast Internet where data compression is not required.
Regularly clearing the cache (once every 1-2 weeks) is the best prevention of memory overflow and does not affect the safety of your personal data and passwords.
Frequently asked questions (FAQ)
Is it safe to delete the Android/data/com.yandex.browser folder manually?
It is safe to delete the contents of a folder cache within this directory - this is analogous to clearing the cache. However, deleting the entire folder or the files inside files is not recommended, as important session data and settings may be stored there, which will lead to the browser resetting.
Why did the browser become slower after clearing the cache?
This is normal. After cleaning, the browser needs to reload all the images, scripts and website styles that it previously took from memory. After visiting several popular resources, the speed will be restored, as the cache will be filled again.
Is it possible to transfer Yandex Browser to an SD memory card?
On modern versions of Android (starting from 6.0 and higher), the ability to transfer applications to a memory card is often blocked by system developers or the application itself to ensure stability. Even if such an option is in the settings, some of the data will still remain in the internal memory.
Does the number of open tabs affect the space occupied?
Yes, it does. Each open tab stores its state in RAM and ROM so you can return to it later. Dozens of open tabs can take up hundreds of megabytes. It is recommended to close unused tabs through the Tableau menu.
How to prevent memory from quickly filling up in the future?
Enable automatic clearing of history and cache when exiting the browser in the privacy settings. Also try not to keep tabs with heavy video content open and regularly check your downloads folder.
