Brand smartphones ZTE have earned popularity due to their good price-functionality ratio, however, owners of budget and mid-budget models often face a lack of free space in the internal memory. When the storage is full, the device starts to slow down, applications crash, and the system constantly sends notifications about lack of space. This is not just an annoying little thing, but a real problem that affects the performance of the entire mobile device.
There are many reasons why memory becomes clogged: accumulation of temporary application files, old photos, duplicate contacts and system garbage. In this article, we will analyze in detail all the available methods for clearing memory on ZTE Android smartphones, from simple built-in tools to advanced methods for managing the file system.
You should not immediately run to the store for a new memory card or think about buying another phone. Often the situation can be corrected by competent optimization deleting unnecessary data. Let's step by step through all the stages of freeing up space so that your gadget can “fly” again.
Analysis of storage fullness and built-in tools
Before deleting anything, you need to understand what exactly is taking up precious gigabytes. The shell MiFavor or pure Android installed on ZTE devices has a built-in memory analyzer. Go to Settings → Memory (or Storage) to see a detailed breakdown by category: applications, images, videos, audio and system files.
Many users ignore this section, relying on third-party apps, although the system analyzer shows the most accurate data on the space consumption of specific apps. Pay attention to the “Miscellaneous” or “Other” section - forgotten downloads and messenger caches are often hidden there. If this partition is taking up too much space, a manual check of the folders is required.
Modern versions of Android on ZTE often offer a Cleanup feature right in the notification menu or Phone Manager app. This is a quick way to remove temporary files, but it is not always effective against deep-seated junk. For deep cleaning, it is better to use specialized sections of the settings.
Periodically check memory usage statistics after installing large games or updating the system - this will help you notice an abnormal increase in space in time.
It is worth considering that the menu interface may differ slightly depending on the firmware version and the specific model of your device. If you do not find the item you need in the specified location, use the search in the settings by entering the request “Memory” or “Storage.”
⚠️ Attention: The system may show the amount of used memory with a slight error due to the characteristics of the file system. Don’t panic if, after deleting a file, the amount of free space differs by several megabytes.
Deleting cache and application data
The largest amount of garbage is usually generated by social networks, instant messengers and browsers. Applications save temporary data to speed up work, but over time this cache grows to unimaginable proportions. To clear it, go to Settings → Applications and select the desired app from the list.
Inside the application menu you will see two important buttons: “Clear cache” and “Clear data”. The first deletes temporary files without affecting your logins and settings. The second one resets the application to its factory state, deleting all accounts and saved information. Be extremely careful when using the second option.
- 🗑️ Telegram and WhatsApp: these messengers save all viewed photos and videos to the phone's memory. It is better to clean them through the built-in settings of the application itself in the “Data and Memory” section.
- 🌐 Browsers (Chrome, Yandex): the site cache can take up hundreds of megabytes. Clear history and cache regularly through the browser menu.
- 📸 Camera and Gallery: some photo editors save intermediate project files that are useless after saving the final image.
Special attention Focus on apps you rarely use. It often happens that a game you played once a month ago continues to store gigabytes of resources. Removing such apps is the fastest way to regain free space.
☑️ Checking heavy applications
Some ZTE system applications also accumulate cache. For example, Google Play services can take up a lot of space due to updates. Clearing the cache Google Play Services is safe and often solves problems with downloading content.
Working with media files and the Downloads folder
The (Downloads) folder is a “black hole” in the memory of most smartphones. Files from the browser, attachments from mail and documents from instant messengers are automatically saved here. Users often forget about them, and they lie dead for years. Download (Downloads) is the memory black hole of most smartphones. Files from the browser, attachments from mail and documents from instant messengers are automatically saved here. Users often forget about them, and they lie dead weight for years.
Use the built-in file manager File Manager or any other explorer to access this directory. Sort files by size or date. Delete old APK installation files, PDF documents you've already read, and random pictures from the Internet.
Photos and videos take up the lion's share of memory. If you don't have the ability to constantly transfer them to your computer, set up automatic synchronization with a cloud service, such as Google Photos. After uploading to the cloud, you can safely delete originals from your device using the “Free up space” function.
How to find hidden large files?
Use the search function by size in the file manager. Enter ">100MB" to find all files larger than 100 megabytes. Often these are forgotten films or archives.
Don't forget to check the folder DCIM. Sometimes unsuccessful takes of pictures, blurry frames or videos taken by mistake accumulate there. Manually revising the gallery at least once a month will help maintain order.
⚠️ Attention: Before bulk deleting files from the “Downloads” folder, make sure that there are no important documents, tickets or receipts among them that you may need in the future.
Transferring applications to an SD memory card
If your ZTE smartphone has memory card slot, this is a great way to relieve internal storage. Although modern versions of Android limit the ability to transfer the applications themselves, it is still possible to move their data or media files.
To transfer, go to Settings → Applications, select the app and click "Storage". If the Change button is active, you will be able to select the SD card as the storage location. However, keep in mind that this may slow down the application slightly, since the speed of the memory card is usually lower than the speed of the internal flash memory.
| Data type | Can be transferred to SD | Recommendation |
|---|---|---|
| Photos and Videos | Yes | Set the camera to save directly to the card |
| Music and Audiobooks | Yes | Ideal for storing a media library |
| System applications | No | Leave only in internal memory |
| Cache of games and heavy apps | Partially | Depends on developer support |
Also, the memory card can be used as internal storage (Adoptable Storage function), but on ZTE smartphones this option is rare and depends on the version of Android. If it is available, the system will format the card and merge it with the main memory.
Using a memory card for photos and videos is the most effective way to save internal space without losing system performance.
Remember that when transferring data to a card, it is important to use high-quality media with a high speed class (Class 10 or UHS-I) to avoid slowdowns when opening files.
Using third-party cleaning utilities
When built-in tools are not enough, specialized applications from the Google Play Market come to the rescue. apps like CCleaner, Clean Master or Files by Google can find duplicate files, residual files from uninstalled applications and empty folders.
However, you should be careful: some “cleaners” themselves consume a lot of resources and show intrusive advertising. Choose proven utilities with high ratings. The "Storage Analysis" function in such applications often finds what the system manager missed.
- 🚀 Files by Google: the official application from the search giant, safe and effective, can suggest files for deletion based on analysis.
- 🧹 SD Maid: a powerful tool for advanced users that allows you to clean system junk and databases.
- 📉 Duplicate Files Fixer: specializes in finding identical photos and documents that take up space twice.
Do not install five different cleaners at once. They can conflict with each other and create additional load on the processor. One high-quality application is enough to maintain order.
⚠️ Warning: Avoid applications that promise to “speed up RAM by 200%” or “cool down the processor.” Most often, these are dummies that simply close background processes, which the system will immediately launch again.
Regular use of such utilities (once a week) will help prevent critical memory filling in the future. Set up automatic scanning if the application supports such a function.
Resetting settings as a last resort
If none of the above methods helped free up enough space, or if the system is unstable due to errors in the file system, you can consider the option of a full reset. This will return the ZTE smartphone to its factory state.
Before performing this procedure, be sure to create a backup copy of all important data: contacts, photos, messages. Use your Google Account or copy the files to your computer. After the reset, all information will be permanently deleted.
To perform a reset, go to Settings → Recovery and reset → Reset settings. Confirm the action and wait for the reboot. The process may take several minutes. After turning on, the phone will be like new, with completely clean memory.
Settings → System → Reset → Delete all data (reset to factory settings)This method is radical, but it is guaranteed to remove all software junk, hidden errors and viruses that may have accumulated over a long period of use. This is the best way to get a “second life” for an old device.
After resetting the settings, do not restore all applications at once from a backup copy. Install only the essentials so as not to return old garbage back to the system.
Frequently asked questions (FAQ)
Why is memory not freed after deleting files?
Perhaps the files were deleted to the “Trash” inside the gallery or file manager. Go to the trash can and empty it completely. Also check whether data is saved in the cloud in offline access mode.
Is it possible to delete system applications on ZTE?
You cannot delete system applications without obtaining root access, you can only disable them. Disabling hides the application and stops its operation, freeing up some RAM, but this will free up little space in the internal storage.
How to transfer WhatsApp to a memory card?
The app itself cannot be transferred, but you can change the path where media files are saved. Go to WhatsApp settings → Chats → Chat backup, however, to completely transfer the folder WhatsApp/Media it is better to use a file manager and manually move the folder to the SD card.
What is the .thumbnails folder and can it be deleted?
This is a folder with thumbnails your photos. It can grow to gigantic sizes. It can be safely deleted, but the system will create it again the next time you open the gallery. It is recommended to periodically clean it through the file manager with the display of hidden files.
Does full memory affect Internet speed?
Directly - no, but indirectly - yes. When the browser's memory is full, there is no place to store the page cache, which can slow down the loading of sites. There may also be problems with updating applications and working with instant messengers.
