Smartphone owners Sony Xperia often face an annoying problem: the device starts to work slower, new applications refuse to install, and the system constantly signals that there is not enough space. This is a classic scenario for mobile gadgetss that have been in operation for more than a year without proper maintenance. The internal memory becomes clogged not only with obvious files, but also with system garbage that accumulates during the operation of Android.
Before resorting to radical measures like resetting to factory settings, it is worth trying to optimize the storage using built-in tools and third-party utilities. Proper cleaning will return gigabytes of free space, but also extend the life of the battery, since the system will not have to constantly index full memory sectors. In this article we will analyze all the effective methods of freeing up space specifically on brand devices Sony.
Analysis of the fullness of the built-in storage
The first step should always be an accurate diagnosis. You should not delete files at random, hoping for a miracle. Modern shells Android, including those used in Sony Xperia, have built-in analysis tools. They clearly show which categories of data occupy the lion's share of gigabytes. Usually this is video, photos or instant messenger cache.
Go to the settings and find the section responsible for memory. Here you will see a color chart where each sector corresponds to a specific file type. Pay special attention to the “Other” or “System Files” item. If this partition has grown to a disproportionate size, logs of uninstalled applications or remnants of updates may be stuck in the system.
⚠️ Attention: Do not try to manually delete files from system folders through the file manager if you do not know their exact purpose. This can lead to unstable operation of the firmware Sony.
Sometimes the problem lies not in the size of the files, but in fragmentation or file system errors. In this case, the standard analyzer may show incorrect data. If the graph is full, and physically you cannot find so many heavy files, it is worth checking the status of the drive through the engineering menu or third-party diagnostic utilities.
An accurate understanding of the structure of occupied space allows you to delete what is unnecessary without affecting important personal data.
Clearing the application cache and system garbage
The fastest way to get back a few gigabytes is to clear the cache. Applications, especially social networks and browsers, save temporary files to speed up loading of content. Over time, this data turns into digital ballast, which only interferes with the operation of the device. On smartphones Sony this process can be automated.
Use the built-in Care Center application or similar system utilities pre-installed by the manufacturer. They have a Cleanup feature that securely deletes temporary files without affecting your logins and passwords. However, for deep cleaning, it is better to go into the settings of each heavy application separately.
Go to the menu Settings → Applications and notifications → Application information. Select the most “gluttonous” app, for example Telegram or YouTube, and click on the “Storage” item. Here you will see a Clear Cache button. Do not confuse it with the “Clear data” button, which will reset the application to its factory state.
- 🧹 Clear your browser cache regularly, as they save copies of all visited pages.
- 📱 Check instant messengers: chat settings often have a function for clearing media files by timer.
- 🔄 Reboot your smartphone after mass clearing the cache for the system to work correctly.
It is also possible to clear the cache of all applications at once through Recovery Mode, but this method requires caution. For the average user, manual selective cleaning of the heaviest apps is sufficient. This will take more time, but guarantees the safety of important settings.
In the settings of some Sony applications there is an “Automatic Maintenance” function, which automatically clears the cache when the device is idle. Activate it in the battery menu.
Managing photos and videos
Media files are the main enemy of free memory. Modern cameras shoot in high definition, and one minute of 4K video can take up hundreds of megabytes. Storing this entire library on an internal drive is impractical and risky. It is necessary to establish a process for sorting and transferring data. Sony Xperia They shoot in high definition, and one minute of 4K video can take up hundreds of megabytes. Storing this entire library on an internal drive is impractical and risky. It is necessary to establish a process for sorting and transferring data.
Use cloud services such as Google Photos or Yandex.Disk. Configure automatic uploading of pictures to the cloud and subsequent deletion of local copies. This feature is called Free Up Space and it works flawlessly. You can view photos in good quality via the Internet without taking up disk space.
If you prefer to store files locally, transfer them to a memory card microSD. Smartphones Sony have a convenient function of formatting the card as internal storage (Adoptable Storage), although in new models it may be limited. In classic mode, simply move the folders DCIM and Pictures to external media via the file manager.
| File type | Average size | Recommended action |
|---|---|---|
| Photo (JPEG) | 3-8 MB | Compressed or cloud |
| Video (1080p) | 150-300 MB/min | Transfer to SD |
| Video (4K) | 400-800 MB/min | Removing duplicates |
| RAW pictures | 25-50 MB | Convert to JPEG |
Don’t forget about the “Trash” folder in the gallery. Deleted photos often remain there for 30 days, continuing to take up space. Empty the Trash manually to finally free up some space. Also check the folder Downloadswhere forgotten installation files and documents are often saved.
Hidden folders with thumbnails
The .thumbnails folder inside DCIM can store gigabytes of thumbnails. They can be safely deleted, but they will be created again the next time you open the gallery.
Working with a memory card and transferring applications
Using an external memory card is a classic solution for owners Sony, many models of which support a slot for microSD. However, simply inserting a card is not enough. You need to properly configure the system so that it perceives the new drive as a full-fledged memory expansion.
In the storage settings, select your memory card and click “Configure”. You can use it as portable storage for media files or try setting it up as internal storage. The second option will encrypt the card, and it will not work on other devices, but will allow you to install applications on it.
⚠️ Attention: When formatting the card as internal memory, all data on it will be destroyed. Be sure to back up your important files before starting the procedure.
Not all applications support transferring to an SD card. Software developers may disable this feature for security or performance reasons. If the “Move” button is inactive in the application settings, it means that the app code does not provide for working with external media. In such cases, only deleting the application will help.
The speed of the memory card directly affects the performance of the smartphone. If you are using an old Class 4 or 6 card, the system may be slow even if there is free space. For modern Sony Xperia it is recommended to use UHS-I Class 10 or higher cards.
☑️ Setting up an SD card
Deleting unused applications and games
Often we we install games “one time” or download utilities that we never use. These apps not only take up space, but can also run in the background, consuming CPU resources. Revision of installed software is a mandatory stage of optimization.
Go through the list of all installed apps. The store Google Play has a section “Manage applications and device”, where you can sort software by frequency of use or size. Delete everything you haven't used in the last three months. This is a strict but effective rule.
Pay attention to pre-installed software from your telecom operator or manufacturer that cannot be removed in the usual way. Such apps are called bloatware. They can be disabled in application settings, which will hide them from the menu and prevent them from running in the background, freeing up some RAM, although they will continue to take up storage space.
- 🎮 Games often weigh more than 2 GB along with a cache of resources - delete them first.
- 🛒 Marketplace applications can be deleted using their mobile versions of sites.
- 📺 Widgets on the desktop also take up resources - delete unnecessary.
If the application is rarely needed, but it is a shame to delete it, consider using its web version. Many services, such as social networks or banks, have excellent mobile sites that do not require installation and do not take up disk space.
Regular audit of installed applications once a month prevents critical memory filling and increases the speed of the interface.
Hidden files and Android folder
Deep in the file system Android hides directories that are not visible to the average user, but can grow to enormous sizes. We are talking about folders Android/obb and Android/data. Additional game files and application data are stored here.
The folder obb contains resources for heavy games. If you deleted the game, but this folder remains, it means that an uninstallation error occurred. You can safely delete the contents of this directory if you are sure that the corresponding games are no longer needed. The system will create it again if necessary.
You need to be careful with the folder. data . Settings and a cache of running apps are stored there. Emptying this folder manually may reset game progress or application settings. It is better to use specialized cleaners that can identify “orphan” files - data from already deleted apps.
⚠️ Attention: The interface and access to the Android folder in the latest versions of Android (11 and higher) is limited by Google's security policy. Access may require connecting to a PC or using special file managers with access rights.
Also check the folder Bluetooth i ShareIt (or analogues) if you often receive files over a wireless network. There are often old documents, APK files and pictures that you have already viewed and forgotten. Removing them is safe and instantly frees up space.
Radical measures: Reset to factory settings
If none of the above methods helped, and the memory continues to be filled with “ghost” data, the last argument remains - a hard reset. This will return the smartphone Sony to the state it was in when purchased.
Before starting the procedure, it is critical to create a complete backup of all contacts, messages and files. After the reset, it will be impossible to recover deleted data without a backup. Make sure that the battery charge is at least 50% so that the phone does not turn off during the process.
Go to Settings → System → Reset settings. Select "Erase all data (factory reset)". The system will warn you about the consequences. Confirm the action and wait for the reboot. This process may take from 10 to 30 minutes.
Settings → System → Advanced → Reset settings → Delete all dataAfter turning on, the smartphone will be clean. Don't restore all your apps from a Google backup at once, as you risk bringing back junk as well. Install apps gradually, checking their necessity. This is the ideal moment to start using the device correctly.
Alternative reset
If the phone does not turn on, you can reset it through the Recovery menu by holding the Volume Down + Power buttons while the device is turned off.
Why is the space not freed up immediately after deleting files?
The system takes time to recalculate free space and update the media database. Sometimes a simple reboot of the device helps, which ends the background indexing processes.
Is it possible to delete the .thumbnails folder on a Sony Xperia?
Yes, this folder can be deleted, it contains thumbnails for the gallery. However, the next time you open a photo, the system will create it again. To permanently save space, it is better to disable the creation of thumbnails in the gallery settings, if this option is available.
Is it safe to use cleaner apps from the Play Market?
Most popular cleaners are safe, but some may contain ads or aggressive notifications. Built-in Android and Sony Care Center tools are usually more effective and safer than third-party software.
What to do if the memory is occupied by “System”?
If the “System” section takes up an abnormally large amount of space, this may be a display error or accumulation of logs. Try clearing the recovery partition cache or resetting the settings if the problem is critical.
How to transfer WhatsApp to a memory card on Sony?
The app itself cannot be transferred, but you can change the path to save media files in the WhatsApp settings. Go to WhatsApp Settings → Chats → Media Visibility and change the storage settings, or manually move the WhatsApp folder to the SD card.
