The situation when the internal memory of a smartphone suddenly runs out is familiar to almost every owner of a device based on Android. The device starts to work slowly, applications close by themselves, and installing updates becomes impossible. Often, users cannot even take a new photo or reply in the messenger due to a critical lack of space.
The main reason lies in the accumulation of temporary files, application cache and forgotten downloads over the years of using the gadget. Modern systems have become more complex, and the requirements for free space for correct operation are growing every year.
In this article we will look in detail at how to free up space without losing important data and what methods are most effective for different versions of the operating system.
Diagnostics and search for the main ones "space eaters"
Before deleting files at random, you need to determine exactly what is taking up gigabytes on your drive. Built-in analysis tools allow you to visualize the distribution of data and identify hidden folders.
Go to the settings and find the section Storage or Memory. Here the system will show a detailed diagram where the categories are highlighted in color: applications, images, videos, audio and system files. Pay attention to the “Miscellaneous” or “Other” item - often the remains of deleted apps are hidden there.
Click on the "Applications" section and sort the list by size. You will be surprised to find that some instant messengers or social networks take up 5-10 GB of space. This is due to the fact that Telegram, WhatsApp and Viber automatically save all received media files to the internal memory.
- 🔍 Check the folder
Download—APK installation files are often located there, which are no longer needed after installing the apps. - 📂 Explore the folder
DCIM—you may have 4K high-resolution shooting enabled, which quickly eats up space. - 🗑️ Find the folder
.thumbnails—this is a hidden cache of gallery thumbnails that can grow to several gigabyte.
⚠️ Attention: Do not delete files from system folders with names likeAndroid,DataorObbmanually through the file manager if you are not sure of their purpose. This may lead to installed apps not working.
Clearing the application cache and system garbage
Cache is temporary data that applications save to speed up their work. Over time, this buffer becomes full of outdated information, which is no longer used, but continues to take up space.
The safest cleaning method is to use standard system tools. Go to Settings → Applications, select a heavy application (for example, YouTube or Instagram) and press the Clear cachebutton. It is important not to confuse this button with the “Clear data” function, which will reset the application to factory settings and delete your logins.
For global cleaning, you can use the built-in "Optimization" or "Device Care" utility, which is available on smartphones Samsung, Xiaomi and other brands. It automatically finds unnecessary files and offers to delete them in one click.
If the built-in tools fail, you can use third-party utilities, but with caution. Many of them contain aggressive advertising or consume a lot of resources themselves. It is better to limit yourself to proven solutions, such as Files by Google.
☑️ Daily memory hygiene
Regularly clearing the cache not only frees up space, but can also solve problems with specific apps freezing. If an application is not working correctly, completely clearing its data often helps restore normal operation.
Media file management and backup
Photos and videos are the main consumers of memory on a modern smartphone. One minute of video in 4K resolution can take up to 400 MB of space, and in a year such material can fill the entire drive.
The ideal solution is to set up automatic synchronization with cloud storage. Services like Google Photos allow you to store pictures in the cloud, leaving only small copies of them on the device or completely deleting the originals after downloading.
Turn on the "Free up space" function in the Google Photos settings. The application will automatically delete from the device those pictures that have already been successfully uploaded to the cloud and are protected from loss.
| File type | Average size | Recommendation |
|---|---|---|
| Photo (JPEG) | 3-5 MB | Store in the cloud |
| Video (1080p) | 100-150 MB/min | Transfer to PC |
| Video (4K) | 350-500 MB/min | Delete from phone |
| RAW pictures | 20-40 MB | Only for pros |
Use a microSD memory card to store your photo archive if your smartphone supports this function. This is the cheapest way to expand your storage.
Don't forget to check the "Trash" folder in the gallery. Deleted photos often remain there for another 30 days, continuing to take up space. Emptying the trash gives an instant result of freeing up space.
Optimization of instant messengers and social networks
Messengers have turned into real harvesters that download gigabytes of pictures, videos and voice messages. By default, many of them are set to automatically download media to the phone gallery.
Go to Settings WhatsApp or Telegram and turn off autosaving media. In Telegram, you can use the built-in cache clearing function with the auto-delete setting. For example, you can set the rule: “Delete the cache if it has not been used for more than 3 days.”
In Viber i WhatsApp there are also “Storage” sections in the settings where you can view the largest chats and delete media files selectively. Often old conversations with memes and postcards take up more space than important work documentation.
⚠️ Attention: Before mass clearing chats, make sure there are no important documents or addresses that are not saved elsewhere. It will be impossible to restore deleted messages without a backup copy.
How to clear the Telegram cache without losing conversations?
In the Telegram settings, select “Data and memory” → “Memory usage”. Click Clear Cache. Your chats, photos and videos will remain on Telegram servers and will be uploaded back if necessary, but space on your phone will be freed up instantly.
It is also recommended to disable the “Save to gallery” function for incoming files. This will prevent duplication: the file will be available inside the messenger, but will not be copied to the shared photos folder.
Deleting unused applications and games
On many smartphones, users store dozens of applications that they have not used for months. Games with heavy graphics, trial versions of services and forgotten utilities not only take up space, but also affect performance.
Go through the list of installed apps and honestly answer yourself: when was the last time you opened this application? If more than six months have passed, you can safely delete it. In the store Google Play there is a tab "Manage applications and device", which shows apps that have not been used for a long time.
Pay special attention to games. Modern mobile hits can weigh 5-10 GB along with additional resources. If you have completed the game or are tired of it, deleting it will free up a huge chunk of memory.
- 🎮 Delete games that you have not played for more than 1 month.
- 🛍️ Demolish store applications if you are not planning purchases in the near future.
- 📱 Check the pre-installed software (bloatware) - some unnecessary apps can be disabled in the settings.
To remove system applications that cannot be removed in the standard way, you need superuser rights or using ADB commands through a computer. However, for the average user, it is safer to simply disable such applications so that they do not update and do not work in the background.
adb shell pm uninstall -k --user 0 com.example.bloatwareRegular audit of installed applications (once every 3 months) helps keep the phone clean and prevents sudden lack of memory.
Transferring data to external media and the cloud
If the internal memory is physically small (for example, 32 or 64 GB), the only option is to transfer the data externally. This is not cleaning, but expanding the available space using external resources.
The use of cloud services (Google Drive, Yandex Disk, Dropbox) allows you to store documents and photo archives for free or for a small fee. Files in the cloud are accessible from any device, but do not take up space on your smartphone.
For owners of smartphones with memory card support microSD the situation is simplified. In the storage settings, you can select a memory card as the default recording location for photos and videos. You can also transfer some applications there, if the developer has not prohibited this function.
Transferring files to a computer via a USB cable is the most reliable way to create an archive. Create a folder on your PC, copy all the old photos and videos from past years there, and then delete them from the phone.
⚠️ Attention: Settings interfaces may differ depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). If you do not find the specified option, use the search in the phone settings.
Buy an OTG flash drive. This is a compact drive that is inserted directly into the phone's charging port. Ideal for quickly transferring movies or heavy files without a computer.
Frequently asked questions (FAQ)
Why does the memory fill up again immediately after cleaning?
Most likely, you have automatic media downloading enabled in messengers or photo synchronization in full resolution. Also, some applications (for example, maps or streaming services) cache data for offline work. Check your startup settings.
Is it safe to delete the Android folder?
No, you cannot delete the entire folder Android . Application data (data) and cache (obb) are stored inside it. Deleting will reset app settings and loss of progress in games. You can only clear the contents of the folder cache within specific applications.
How to transfer applications to a memory card?
Go to Settings → Applications, select the desired application. If the function is available, there will be a button Storage, and in it an option Change or Move to SD card. If there is no button, the developer has disabled the transfer.
What is a page file and will it help? it?
The swap file uses part of the internal memory as RAM. If you don't have much onboard memory, creating a page file will only make the problem of running out of space worse. This function is only useful if there is not enough RAM, but there is too much free disk space.
Is it possible to increase the phone's memory programmatically?
It is impossible to physically increase the built-in memory chip programmatically. All applications that promise “increased memory” actually just clear the cache or work with virtual memory (page file), which does not add real space for storing photos and videos.
