Owners of the popular budget smartphone Redmi 7 often face a lack of free space in internal memory. Despite the availability of versions with 32 or 64 gigabytes of storage, modern applications and multimedia files quickly fill the available space. The MIUI system installed on the device also takes up a significant part of the volume, which leads to a slowdown of the gadget.
When internal storage is overcrowded, the phone starts to run slower, applications can crash, and new programs stop being installed. Fortunately, there are several proven ways to optimize resource usage and actually increase the available volume for your needs. In this article, we will detail how to clean, transfer data, and expand functionality without losing warranty.
Before embarking on radical measures such as resetting or flashing, it is worth using the built-in tools of the system. Proper management of files and cache allows you to free up to 30-40% of space, which is a critical indicator of performance for a budget device.
Analysis of internal storage occupancy
The first step to freeing up space is to understand what takes up precious gigabytes. In the Android operating system, as well as in the MIUI shell, there are built-in disk space analyzers that allow you to visually evaluate the distribution of files into categories: applications, images, videos, documents and system debris.
You have to go to the settings and find the partition that's responsible for the storage, and here the system will show you a data distribution diagram, and it often turns out that the lion's share of the memory is occupied by the cache of messengers like Telegram or Viber, which by default store all the media files received, and also a significant amount can be occupied by system updates or remnants of remote programs.
It is important to distinguish between "app-occupied" and "multimedia occupied." If photos and videos are the majority, the solution is to move them, and if memory is clogged with system files or cache, you will need to clean up more deeply through special utilities or manually delete temporary files.
- 📱 Go to Settings. → The phone. → Storage for viewing general statistics.
- 📂 Use the Explorer app to sort files by size and date.
- 🗑️ Pay attention to the Downloads folder, where unnecessary installation files often accumulate. APK.
⚠️ Note: When analyzing storage, do not delete files with the.obb extension or system folders with names like "Android" unless you are sure about their content.
After the initial analysis, you will get a clear idea of where to go. If less than 1 GB is left free, the system can begin to warn of a critical shortage of space, and you need to act immediately.
Cleaning the cache and removing system debris
The safest and fastest way to free up space is to clear the app cache. Cache is a temporary file that speeds up programs but grows to huge sizes over time. Xiaomi Redmi 7 has a built-in Cleanup tool available through the Security app.
But standard cleaning often doesn’t affect the social media cache and messengers deeply. To work more efficiently, you need to go to the settings of each heavy app separately, for example, in YouTube or Chrome browser you can clear history and temporary files, which immediately frees up several hundred megabytes.
There is also the concept of "system garbage" - error logs, remnants of deleted programs and temporary update files, their removal is safe, because they do not carry user value. Regular cleaning of this data helps to maintain the speed of the Snapdragon 632 processor installed in this model.
☑️ Checklist for quick cleaning
And remember the DCIM folder, where deleted photos are stored, and often after they're deleted, they move to the cart inside the gallery and continue to occupy space for 30 days, and cleaning the cart is a must-have for freeing up space.
- 🧹 Open the Security app and select the Cleanup section".
- 📸 Check out the basket in the Gallery and the album "Recently deleted".
- 💬 In WhatsApp and Telegram settings, select “Data Use” to clean up your media cache.
Regularly performing these procedures, at least once a week, will allow you to keep a few gigabytes free, which is especially true for models with a basic memory configuration, where every megabyte counts.
Using a MicroSD Memory Card to Expand
The most efficient hardware solution for Redmi 7 is to install a microSD memory card. The smartphone supports cards up to 256 GB (officially), although in practice, more capacious drives often work, which allows you to transfer all heavy media files to an external medium.
Once the card is installed, the system will suggest using it as "Portable Storage" or "Internal Storage"; the first option is preferable for this model, since it provides compatibility with other devices and less memory wear.
Difference between recording formats
To move files, you need to use a file manager. In a standard MIUI Explorer or a third-party one, like Total Commander, you can select photo and video folders and select Move it by pointing the path to the memory card, which will free up internal memory, leaving only system files and applications on it.
| Type of data | Recommended storage location | Impact on speed |
|---|---|---|
| Photos and videos | Memory card (SD) | Minimum |
| Music and Films | Memory card (SD) | Absent. |
| Annexes (Games) | Internal memory. | High (on SD, it can be braked) |
| System files | Internal memory. | Critical |
It is important to purchase memory cards with a speed class of no lower than Class 10 or UHS-I. Slow cards can cause delays when shooting videos or opening heavy files, which will create the illusion of lack of power of the smartphone itself.
Transfer of applications to an external drive
The issue of installing applications on a memory card in MIUI is not as clear-cut as in pure Android. By default, the system seeks to install all programs in internal storage for maximum speed, but for some applications, portability is available.
To check this possibility, you need to go to Settings. → Annexes → All applications. When you select the desired program, find the "Move to" button. SD-If it's active (not grey), you can make room. If the button is missing, the app developer has banned the transfer, and you can't get around it with standard methods.
💡
Some system applications can only be moved with special rights or ADB-It requires deep knowledge and can disrupt the stability of the system.
There is a method of forced porting through the developer menu, but it works unstable on different versions of the firmware. Activating this feature can cause applications to run slower or stop updating through Google Play.
- 🔧 Go to Settings. → About the phone and 7 times click on "Version" MIUI".
- 🛠 Come to the extra. → For developers.
- 💾 Find the item "Allow applications to be saved on external drive" and activate it.
Once this option is enabled in the application management menu, you may be able to transfer it, but it is worth remembering that removing the memory card will make these applications inoperable before it is returned.
Optimization of the work of messengers and social networks
The main memory eaters in modern smartphones are messengers. WhatsApp, Telegram, Viber and Instagram store every photo and video viewed in cache. During a year of use, such cache can reach 5-10 gigabytes, which is a huge figure for Redmi 7.
In the settings of each messenger, you can limit the auto-save of media files to the gallery. This will not remove them from the chat, but will stop duplicating files into the phone’s shared memory. It is also recommended to regularly use the built-in “Clear Cache” feature in the application’s storage settings.
Telegram has a separate cache size limit setting, which will automatically delete old files if they exceed the limit, while the correspondence history and the ability to re-download remain intact.
⚠️ Note: When you clean your messenger data through your Android system settings (Erase Data button), you may lose your entire correspondence history if it is not synced to the cloud.
Regularly auditing subscriptions in channels and chat rooms also helps: disabling media downloads in groups where you rarely go significantly reduces the load on disk space and Internet traffic.
Use of cloud storage and USB-OTG
If you don't have a physical memory card and your internal storage is crowded, cloud services come to the rescue. Google Photos, Yandex.Disk or Mi Cloud let you store photos and videos online. Google Photos' "Free space" feature automatically removes images from your device that have already been uploaded to the cloud.
Another effective method for one-time transfer of large amounts of data is the use of USB-OTG technology. Redmi 7 supports the connection of external flash drives through the Type-C adapter (or Micro-USB depending on the port revision), you can copy the archive of movies or photos to a flash drive, delete them from the phone, and if necessary, reconnect the drive.
Cloud storage requires an Internet connection, which is not always convenient, whereas USB-OTG allows instant access to files without traffic consumption.
Using streaming services instead of downloading music and movies also saves space, and viewing online in good quality is possible even with the fastest mobile Internet, and you need to store only the essentials locally.
