Modern brand smartphones BQ offer excellent value for money, but over time, even the most productive models begin to work slower. The main reason for the speed drop is that the internal storage is full. When free space approaches the critical minimum, the operating system Android cannot effectively manage temporary files and processes.
Users often notice that applications take a long time to open, the camera works with a delay, and notifications arrive late. This is a direct signal of what needs to be done general cleaning in the system. Do not panic or immediately take the device to a service center.
In most cases, the problem can be solved yourself using built-in tools or special utilities. In this article, we will analyze in detail all the methods for freeing up space on devices BQ, from simple actions to advanced optimization techniques.
Diagnostics of occupied space
Before you start deleting data, you need to understand what exactly is taking up space in the memory of your device. The system Android provides detailed statistics on storage usage. To access it, go to the menu Settings and find the section Memory or Storage.
Here you will see a color chart, where file categories are indicated in different colors: applications, images, videos, audio and system data. Pay attention to item Cache and Other. It is these sections that often grow to gigantic proportions, absorbing gigabytes of useful space.
If the “Applications” category takes up the lion’s share of space, it means you have a lot of heavy games or apps installed. If there is a predominance of media files, the problem can be solved by transferring photos and videos to a memory card or to the cloud.
⚠️ Attention: Do not delete files from the “System Data” or “Android” section if you do not know their exact purpose. This may lead to unstable operation of the operating system or loss of important settings.
Clearing cache and temporary files
The safest and fastest way to free up space is to delete cached data. Cache is temporary files that applications save to speed up their work. However, over time, these files become outdated and become useless ballast.
You can clear the cache of each application individually through the settings menu. Go to Settings → Applications, select the desired app and press the button Clear cache. It is important not to confuse this button with the option Clear data, which will reset the application to its factory state.
For mass clearing, use the built-in utility. Smartphones BQ often come with a “Cleaning” or “Phone Manager” application pre-installed. Launch it and click the scan button. The system will automatically find temporary files, remnants of deleted apps and advertising junk.
- 🗑️ Removing the browser cache can free up from 100 MB to 1 GB of space.
- 📱 Clearing the cache of social networks (VKontakte, Telegram) often gives the greatest effect.
- 🔄 Regular cleaning once a week prevents critical memory filling.
Use the “Acceleration” function in the BQ phone manager not only to clear memory, but also to close background processes, which will temporarily increase performance.
Managing installed applications
Many users install dozens of applications that they use stop using it after a month. Such apps not only take up space, but also consume RAM while running in the background. Regular audit of installed software is the key to smartphone performance.
Go to the list of all applications and sort them by size. It often turns out that one game or photo editor takes up more space than a hundred small utilities. Ruthlessly delete what you have not used in the last three months.
Pay attention to system applications that cannot be deleted in the standard way. They can disable. When disabled, the app stops updating and running in the background, and its updates are deleted to free up space. To do this, in the application menu, press the button Disable.
Settings → Applications → [Select application] → DisablePay special attention to instant messengers. Telegram and WhatsApp tend to save all received media files to the device memory. In the settings of these applications, you can disable auto-saving of photos and videos to the gallery.
⚠️ Attention: Before deleting banking applications or apps with important data, make sure that you remember logins and passwords for logging in, as restoring access may be difficult.
☑️ Application audit
Working with media files and documents
Photos and videos are the main consumers of memory on any smartphone. Modern cameras BQ take high-resolution images that take up a significant amount of space. It is not practical to store thousands of photos in the internal memory.
The ideal solution is to use cloud services such as Google Photos. Set up automatic uploading of pictures to the cloud with the “Free up space” function. This option will delete from the device those photos that have already been successfully uploaded to the server.
If you do not trust the cloud, use a memory card microSD. In the camera settings, specify saving all new pictures and videos directly to an external card. Old files can be transferred manually through the file manager.
| File type | Average size | Recommendation |
|---|---|---|
| Photo (JPEG) | 3–5 MB | Transfer to cloud or SD |
| Video (Full HD) | 100–300 MB/min | Delete after viewing |
| Downloaded files | Miscellaneous | Regular cleaning of the Download folder |
| Audio (MP3) | 5–10 MB | Streaming instead of storage |
Don't forget to check folder Download (Downloads). Application installation files (APK) that have already been installed, as well as documents from mail that are no longer needed, often end up there.
How to find duplicate files?
Built-in Android tools do not always see duplicates. To search for identical photos and videos, it is recommended to install a specialized application, for example, Files by Google, which has a duplicate search function.
Using a memory card and cloud storage
If the internal memory of your BQ smartphone is limited (for example, 16 or 32 GB), you cannot do without an extension. Most models support the installation of memory cards up to 128 GB or more.
After installing the card microSD it can be used as portable storage or, in some versions of Android, as part of the internal memory. The second option is called Adoptable Storage. When you format a card as internal memory, the system encrypts it and it becomes inaccessible to other devices without a reset.
This allows you to install applications directly to the memory card and save all media files there by default. However, it is worth considering that the speed of memory cards is usually lower than the speed of the built-in drive, which may slightly affect the performance of heavy applications.
Cloud storage is an excellent alternative to a physical card. Services like Yandex.Disk, Google Drive or Dropbox provide a free volume of 5 to 10 GB. This is enough to store important documents and backup copies of contacts.
⚠️ Attention: When formatting a memory card as internal memory, all data on it will be permanently deleted. Be sure to back up your important files before this procedure.
Combining cloud storage for photos and a memory card for applications is the best strategy for budget smartphones with a small amount of internal memory.
Radical measures: Factory reset
If none of the above methods helped free up enough space, or if the phone is extremely unstable, you should consider a full reset. This procedure will return the device to the state it was in when purchased.
Before starting the procedure, it is critical to create backup all data. Resetting will delete absolutely everything: contacts, messages, photos, installed applications and settings. Make sure your contacts are synced with your Google account.
To perform a reset, go to menu Settings → Backup and reset → Reset settings. Confirm the action by entering your password or pattern. The process will take a few minutes, after which the phone will reboot and begin the initial setup.
Settings → System → Advanced settings → Reset settings → Delete all dataAfter switching on do not rush to restore all applications from a backup copy at once. Try setting up your phone as new and installing only the minimum required apps. Often this allows you to avoid transferring old “garbage” to the new system.
What to do if the phone does not turn on after a reset?
If after resetting the device is stuck on the logo, try performing a Hard Reset through the Recovery menu. To do this, hold down the Volume Up + Power buttons until the menu appears, then select Wipe Data/Factory Reset.
Frequently asked questions (FAQ)
Why does the memory fill up again immediately after cleaning?
Most likely, you have autosave activated in messengers (Telegram, WhatsApp) or social network applications. They constantly download new photos and videos. Also check if you are configured to automatically download application updates only via a mobile network or Wi-Fi without restrictions.
Is it possible to delete the Android folder on a memory card?
No, you cannot delete the entire folder Android . It stores the cache and data of your applications. If you remove it, games and apps will be reset to their original level, and some may no longer run. You can only delete the contents of subfolders of specific deleted games.
How to transfer applications to a memory card in BQ?
Go to Settings → Applications, select the desired application. If the developer has allowed the transfer, there will be a button Edit or Move to SD card. If there is no button, then the application does not support working on external media.
Is it safe to use third-party apps for cleaning (Clean Master and analogues)?
Modern versions of Android have built-in effective cleaning tools. Third-party “cleaners” often consume a lot of resources themselves, show intrusive advertising and can delete necessary files. It is recommended to use only the built-in Phone Manager application or Files by Google.
What is a page file and should it be increased?
The page file uses part of the internal memory as RAM. On smartphones with low RAM (1-2GB), this may help keep more apps open, but it will wear out the memory faster. In BQ phones, this function is usually managed automatically by the system; manual intervention is not required.
