Brand smartphones BQ, popular due to their affordable price and functionality, inevitably begin to work slower over time. The main reason for this phenomenon lies in the internal storage being full. The operating system Android is designed in such a way that for it to work correctly it always requires free space, which acts as a buffer zone for temporary operations.
When the free space runs out, the device begins to slow down, applications crash, and new apps stop being installed. The user faces annoying notifications about low memory. The solution to the problem is competent and regular cleaning of the system from accumulated digital garbage.
In this guide we will look at proven methods for freeing up space that are suitable for most models, including the BQ Next, BQ Magic i BQ Strikeseries. You will learn to distinguish important system files from unnecessary remnants of deleted apps and safely optimize the operation of your gadget without losing personal data.
Analyzing storage fullness and searching for large files
Before you begin active removal steps, you need to understand what exactly is taking up precious gigabytes. It often turns out that half of the memory is taken up by forgotten videos or high-resolution photos. Built-in tools Android allow you to quickly visualize the storage structure.
First, go to the settings menu of your device. The path may differ slightly depending on the firmware version, but the logic remains the same for all devices BQ. Find the section responsible for memory and study the proposed diagram.
The system will show the distribution of space between applications, images, videos, audio and system files. If the "Applications" category takes up the lion's share, it is worth checking the list of installed apps. Often there are games that you have not played for several months, or heavy navigators with offline maps.
⚠️ Attention: When analyzing memory, pay attention to the “Downloads” folder. Files downloaded from a browser or received through instant messengers often remain there for years and weigh hundreds of megabytes.
Pay special attention to junk files that remain after deleting applications. They are not visible in the standard list of apps, but they take up space. To detect them, you can use the built-in file manager or third-party utilities, but manually checking folders often gives the best result.
Clearing cache and temporary application files
The fastest way to free up space is to delete the cache. Cache is temporary data that applications save to speed up their work. Over time, this data can grow to gigantic proportions, especially for social networks and video services.
To clear it, open your phone's settings and go to the "Applications" or "Application Manager" section. Select the application that takes up the most space (often it YouTube, Telegram or Instagram). Inside the application menu, find the “Storage” or “Memory” item.
Here you will see two buttons: “Clear cache” and “Clear data”. Click only on the first one. The second button will delete all your logins, passwords and settings within that particular application, which will require re-authorization.
Repeat this procedure for all resource-intensive apps. It's safe and won't affect your personal photos or contacts. After clearing the cache, you may notice that applications launch a fraction of a second slower when you first start, but this is normal - they will simply re-create the necessary temporary files.
Use the built-in "Clean" function in the multitasking menu (the square button or swipe up) if your version of the BQ shell has it. It automatically deletes the cache of background processes.
Removing system garbage and residual files
In addition to the cache, the system accumulates so-called “tails” - configuration files, error logs and remnants of deleted apps. It is difficult to find them using standard Android tools, so many users turn to specialized cleaners.
However, be careful with aggressive optimizer apps. They can remove important system shortcuts or, conversely, become a source of advertising themselves. The best approach is to use proven tools, such as Files by Google or the built-in file manager.
In the file manager, pay attention to the folders with the names of deleted applications. Also check the root directory for files with the extension .log or .tmp. You can safely delete them.
For deeper cleaning, you can use the developer mode, but this requires caution. For an ordinary user, it is enough to regularly check the folder Android/datawhere the data of games and heavy applications is stored. If you delete a game, the folder with its name may remain and weigh several gigabytes.
Is it worth using root access for cleaning?
Obtaining superuser rights allows you to remove system junk, but this will void the warranty and can lead to unstable operation of BQ. It is not recommended to do this unless absolutely necessary.
Optimizing multimedia and working with cloud storage
Photos and videos are the main consumers of memory. Modern cameras shoot in high definition, and one minute video can weigh 100-200 MB. It makes no sense to store all this on the phone’s built-in storage. BQ doesn't make sense.
The ideal solution would be to set up automatic synchronization with cloud services, such as Google Photos or Yandex.Disk. After uploading the originals to the cloud, you can use the “Free up space” function, which will delete local copies, leaving only the preview in the gallery.
It is also worth checking the messenger settings. By default, all received media files are automatically saved. Disable this feature in chat settings so that pictures from groups do not automatically fill up memory. WhatsApp And Telegram By default, all received media files are automatically saved. Disable this feature in chat settings so that pictures from groups do not automatically fill up the memory.
If clouds are not an option for you, consider purchasing a memory card microSD. Many BQ models support installation of cards up to 128 GB and higher. Transfer all photos, videos and music to external media through the file manager menu.
| Data type | Recommended action | Deletion security |
|---|---|---|
| Application cache | Regular cleaning | Safe |
| Download folder | Manual sorting | Safe (check files) |
| Photo and Video | Transfer to the cloud/to SD | Only after |
| Files.apk | Removal after installation | Safe |
Radical methods: Reset to factory settings
If the BQ phone works extremely slowly, the memory is constantly full, and simple methods do not help, the last resort is a complete reset. This process will return the device to its out-of-the-box state, erasing absolutely all user data.
Before starting the procedure, it is critical to create a backup copy. Save your contacts to your Google account, and transfer photos and documents to your computer or the cloud. After the reset, it will be impossible to restore anything.
To perform a reset, go to Settings → System → Reset settings (path may vary). Select "Reset settings" or "Erase all data". The device will reboot and begin the cleaning process, which may take 10-15 minutes.
⚠️ Attention: Make sure the battery charge is at least 50-60% before starting the reset. Interrupting the process due to a discharge can lead to damage to system partitions and the inability to turn on the phone.
After completion, you will receive a clean system without garbage, old settings and app conflicts. This is often a “second wind” for old smartphones, allowing you to extend their service life for another year or two of active use.
☑️ Ready for a full reset
Prevention of memory overflow in the future
To prevent the problem from returning in a month, you need to develop the habit of monitoring your digital in order. Regularity is the key to success. It is enough to spend 5 minutes once a week checking your downloads folder and deleting unnecessary screenshots.
Use the Lightbox function in Google Photos to delete unsuccessful frames immediately after shooting. Don't keep dozens of identical photos "just in case." Also delete application installation files (.apk) immediately after installing apps.
Keep an eye on system updates. BQ engineers and Android developers are constantly optimizing the file system. New firmware versions may contain bug fixes that lead to the growth of logs and garbage.
The main secret of a clean phone is not to accumulate files “for later.” If you don't need a file right now, chances are you won't ever need it.
Remember that built-in memory is faster and more reliable when it is no more than 80-85% full. Always leave at least 1-2 GB of free space for system operations and caching.
Why does the memory fill up even if I don't download anything?
This happens due to background processes running. Messengers save history, browsers cache pages, and application analytics systems write logs. Without regular cleaning, this “invisible” load can take up several gigabytes.
Is it possible to remove system applications on BQ?
Removing standard applications (calendar, clock, standard Google services) without root access is often impossible or requires complex manipulations via ADB. It is not recommended to do this, as it may interfere with the operation of the system.
Does full memory affect Internet speed?
Indirectly - yes. When memory is critically low, the system has nowhere to buffer data, the browser cache does not work effectively, which can lead to longer loading pages and slowdown of online videos.
