Brand smartphones Lenovo have earned popularity due to their price-quality ratio, but even powerful devices can slow down over time. The main reason for performance degradation is full internal storage. When the free space reaches zero, the operating system Android begins to become unstable, applications crash, and the system freezes. Owners of series models Vibe, K6 or newer Legion often encounter this problem after a year of active use.
Freeing up space is not just about deleting old photos. This is a complex process that includes managing the cache, moving data to external media, and disabling unnecessary system services. In this article, we'll take a closer look at how to safely and efficiently free up gigabytes on your device without deleting important information. You will learn about hidden shell functions and tools that will help restore your phone to its former speed.
Analysis of occupied space using built-in tools
Before deleting files at random, you need to understand what exactly is taking up most of your storage. Modern versions Android devices Lenovo have an excellent analytical tool built into them. It allows you to visualize the distribution of data and identify memory “eaters”. Typically, the largest volumes are occupied by multimedia, messenger cache and installed games.
To access this information, go to the menu Settings → Storage. Here the system will show an overall chart of space usage. Pay special attention to section Applications and Images. Often, users forget about downloads from the browser or old videos that were watched only once. The system may offer automatic garbage cleaning, but manual control is always more reliable.
⚠️ Attention: Before deleting any system files or folders with unknown names, make sure that they do not apply to the operation of the applications you have installed. Deleting critical data may cause the software to malfunction.
If you see that the “Other” section is taking up an abnormally large amount of space, this may indicate an accumulation of temporary update files or residual data from uninstalled apps. In this case, a deeper cleaning is required, which we will look at in the following sections. It is also worth checking the folder Download, which often turns into a dump of installation files APK.
Managing cache and application data
The fastest way to free up space is to clear the application cache. Cache is temporary data that apps save to speed up their work. Over time, these files grow to gigabytes, especially on social networks and instant messengers. On smartphones, this operation can be performed for all apps at once, or selectively. Applications Lenovo This operation can be performed for all apps at once or selectively.
Go to Settings → Applications and select the heaviest application, for example, YouTube or Telegram. Inside the application menu, find the item Storage. Here you will see two buttons: “Clear cache” and “Clear data”. It is important to understand the difference: clearing the cache is safe and deletes only temporary files, while clearing data resets the application to its factory state, deleting logins and settings.
- 🗑️ Browser cache - often takes up hundreds of megabytes due to saved images from visited sites.
- 📸 Gallery cache - contains thumbnails of all your photos and videos, can grow with a large media archive.
- 💬 Messenger cache - saves all viewed photos and videos from chats, even if you have already seen them.
For mass clearing on some shells ZUI (Lenovo firmware) has a built-in optimizer. Launch the application Phone Manager or Securitythat is preinstalled on the device. The Junk Cleanup feature will scan your system and prompt you to remove safe temporary files. This action can be performed regularly, for example, once a week, to keep the system in good shape.
Use the "Deep Clean" function in the Lenovo proprietary manager only after creating a backup copy of important data, as the algorithm may sometimes suggest deleting files that you planned to save.
Transfer files to the card memory and to the cloud
If the device's internal memory is limited (for example, 32 or 64 GB), it is critical to use external drives. Most smartphones Lenovo support format cards microSD. Transferring photos, videos and music to a memory card instantly frees up precious internal space for operating the system and installing applications.
To transfer files, open the application Files or File Explorer. Select the desired media files in the internal memory, press the selection menu and select the option Move or Copy. Select your memory card SD cardas the destination. After transfer, be sure to check whether the files open from the new location before deleting the originals.
| Data type | Recommended storage location | Advantages |
|---|---|---|
| Photo and Video | SD card or Cloud | Saving up to 80% internal memory |
| Documents (PDF, Doc) | Cloud storage | Access from any device, protection against loss |
| Music and Podcasts | SD card | Fast playback without the Internet |
| Backups | PC or Cloud | Reliable storage of data when reset |
An alternative to a physical memory card are cloud services such as Google Drive, Yandex.Disk or proprietary cloud Lenovo. Set up automatic photo synchronization. The application Google Photos has a “Free up space” function, which deletes from the device those pictures that have already been successfully uploaded to the cloud. This is an ideal option for those who do not want to bother with memory cards.
☑️ Preparing for data transfer
Removing duplicates and hidden system files
When using a smartphone, duplicate files are often created. This can happen when documents are unsuccessfully saved, images are re-downloaded from chats, or the camera malfunctions. On phones Lenovo such files can be located in folders DCIM/.thumbnails or in the root directories of instant messengers. Removing them is safe and returns hundreds of megabytes.
To find duplicates, you can use third-party utilities from Google Play, for example, Files by Google. This is the official app from the search giant and works great on Lenovo devices. It scans your memory and offers to delete identical photos, old screenshots and unused applications. The interface is intuitive and does not require special knowledge.
It is also worth paying attention to the folder .Trash or Trash in the gallery. Many users delete photos but forget to empty the trash, where they are stored for another 30 days. Go to the gallery settings, find the section with deleted items and do a complete cleanup. Only after this will space be physically freed up in the system.
⚠️ Attention: The interface and folder names may vary depending on the Android version and ZUI firmware. Always check the latest manuals for your specific model, as manufacturers often update the menu structure.
Where to look for hidden folders with garbage?
The most “cluttered” directories are usually located along the paths: /Android/data/ (game cache), /WhatsApp/Media/ (media from chats) and /Download/ (downloads). Be careful when deleting files from the Android/data folder, delete only the contents of the folders of deleted games.
Optimizing the work of instant messengers and social networks
Messengers like WhatsApp, Viber i Telegram are the main culprits of memory shortage on modern smartphones. They save every photo and video received to the phone's gallery by default. On devices Lenovo with little memory, this quickly becomes a critical issue. The solution lies in the settings of the applications themselves.
Go to the messenger settings, section Data and storage. Turn off automatic media downloads for mobile networks and Wi-Fi if possible, or set it to save only important files. T Telegram you can use the built-in cache auto-delete function: set a limit, for example, 500 MB. The application will automatically delete old files as soon as the cache exceeds this limit, while the conversations will remain untouched.
- 📵 Turn off autosave in WhatsApp to prevent media from being duplicated in the Lenovo gallery.
- 🧹 Use the Clear feature regularly cache" inside the Telegram settings.
- 🚫 Prohibit social networks (VK, Instagram) from saving a copy of downloaded photos to the device memory.
In addition, check mailing lists and groups. They often send heavy videos that you are not interested in. Leave inactive groups or turn on Silence mode to reduce your interaction with memory-clogging content. This will not only free up space, but also reduce the load on the processor and battery of your smartphone.
Setting up automatic cache clearing inside messengers is a “one-time” action that saves gigabytes of memory in the future without your participation.
Radical measures: Reset to factory settings
If none of the above methods worked and your phone is still running slowly, the system may be too fragmented or infected with hidden malware. In this case, the only effective solution is a full reset to factory settings (Hard Reset). This will return the phone Lenovo to the state it was in when you purchased it.
Before performing this procedure, it is critical to create a complete backup of all data. Resetting will delete absolutely everything: contacts, photos, applications and settings. Make sure your data is synchronized with Google Account or copied to your computer. After that, go to Settings → Backup and reset → Reset settings.
Settings -> System -> Reset settings -> Delete all dataThe process will take a few minutes, phone will reboot and begin initial setup. You will notice a significant increase in speed and several gigabytes of free space. This is the best way to “rejuvenate” an old device that has been used for a long time without formatting. However, resort to this method only as a last resort.
⚠️ Attention: Make sure that the battery level is at least 50-60% before starting the reset. Interrupting the process due to a low battery may damage the phone and require flashing it at a service center.
What to do if the phone does not turn on after a reset?
In rare cases, if the firmware fails, the device may freeze at the Lenovo logo. Try performing a hard reboot by holding down the Power and Volume Up buttons for 10-15 seconds. If it doesn’t help, you will need to flash it via a PC.
Prevention and maintenance of system cleanliness
To prevent the problem of low memory from returning in a month, you need to develop digital hygiene habits. Do not install applications “in reserve”. Every installed application, even if you don't use it, takes up space and can run in the background, creating a cache. Regularly audit installed apps in the menu Settings → Applications.
Use cleaning widgets on the main screen if your firmware ZUI allows it. One tap on the widget will start scanning and removing garbage. Also try not to store high-definition movies and TV shows on your phone for longer than the viewing time. Streaming services allow you to watch content online without taking up storage space.
Remember that RAM (RAM) and built-in memory (ROM) are different things, but they are related. If the built-in memory is full, the system has no place to create swap files, which leads to interface slowdowns. Maintaining at least 15-20% of free disk space is the key to stable operation of your Lenovo for many years.
Set a rule: once a month, delete the 3 most unused applications and empty the trash in the gallery. It will take 2 minutes, but will preserve the performance of the phone.
Is it possible to delete system applications on Lenovo to free up space?
Deleting system applications (bloatware) is only possible with superuser rights (Root). Without root access, you can only disable them in the settings, which will hide the icon and stop the application, but will not completely delete its files from the disk. This gives a slight gain in space, but can speed up work.
Why is space not freed up after deleting files?
A common reason is that the files are in the “Trash” of the gallery or file manager. It's also possible that the deleted data was a cache that the application immediately started regenerating. Check the synchronization settings of cloud services, they may take up space with backup copies.
How to transfer applications to an SD card on Android Lenovo?
In modern versions of Android, this function is limited. Go to Settings → Applications, select the application and click Storage. If the button Change is active, you can transfer the application to the card. If there is no button, then the application developer has prohibited the transfer, and it cannot be done without complex manipulations.
Is it safe to use third-party cleaners?
Most popular cleaners (Clean Master, CCleaner, etc.) are safe, but often contain advertising and consume resources themselves. The built-in Android tools and file manager are usually sufficient. Avoid apps that require suspicious permissions or promise “5x speedup.”
What is the page file and how does it affect memory?
The page file is an area on the built-in memory that the system uses as temporary RAM. If the internal memory is completely full, the system cannot create this file, which leads to severe freezes. Therefore, always leave at least 1 GB of free space.
