How to effectively clean the space on the phone Xiaomi Redmi 9

Smartphones of the Redmi line from Xiaomi are deservedly popular due to the excellent price-quality ratio, but owners of the Redmi 9 model often face a lack of free space. The built-in memory of the device is quickly filled with multimedia files, application cache and system logs, which leads to a noticeable slowdown in the MIUI interface. The user can observe long delays when opening programs or even sudden departures of running games.

Timely storage cleaning is a critical procedure to keep Android operating system stable. Ignoring disk overflow warnings can make it impossible to install security updates or receive new messages in messengers. In this detailed guide, we will break down all proven ways to free gigabytes on your device without losing important data.

Analysis of vault occupancy

Before you start deleting files, you need to know exactly what takes up the lion's share of the available volume. MIUI provides built-in tools for detailed analysis that allow you to see the distribution of space between applications, images and system files. Without this step, you risk deleting the necessary documents, leaving a heavy but useless cache.

To get started, open the standard Security app, which is preinstalled on each Xiaomi device. Select Cleanup from the menu, after which the system will automatically scan the device and issue a preliminary report. More detailed statistics can be found in the Settings section, then About Phone and Warehouse, where the employment chart is visualized.

Note the “Other” category, which often hides forgotten browser downloads or remnants of deleted programs. System data can also grow over time, taking up several gigabytes, especially if you actively use streaming services or navigators without first cleaning the maps.

⚠️ Before mass deleting files from folders with unfamiliar names, make sure they do not contain important configurations of the applications you installed to avoid a malfunction in their work.

The analysis shows that user media and social media are the most common, and the following is a table showing the typical space distribution on a medium-load device:

Type of dataApproximate volumeImpact on the system
Photos and videos10-20 GBHigh (main storage)
Applications (WhatsApp, Telegram)5-15GBCritical (media cache)
Games2-10GBAverage (depending on quantity)
System cache1-3 GBLow (accumulating)

Use of built-in optimizer

The easiest and safest way to start cleaning is to use the regular Cleanup tool, which is integrated deep into the MIUI shell and has access to system areas closed to third-party programs, and allows you to delete temporary files, installer package residues and advertising debris in just a few touches.

Launch the Safety app and press the large green Cleanup button. The system will prompt you to remove the debris found, which can range from a few megabytes to a gigabyte. Once the primary cleanup is complete, it is recommended to go to the Deep Cleanup section, where more subtle settings are available.

In deep clean mode, you'll be able to select specific file categories to delete, such as large files, rarely used apps or duplicate photos.Automatic cleanup can be set up for regular maintenance, but manual control for the first time will be more efficient.

Special attention should be paid to the section with similar photos, which helps to find serial shots and choose the best ones by removing blurred frames, which saves significant space without losing important moments.

⚠️ Attention: Deep cleaning function may suggest removing APK-installer files; make sure you didn’t plan to manually install these apps in the near future.

Regular use of the built-in optimizer helps keep the system on track, but it is not enough to achieve maximum results, and you will need to work manually with heavy applications.

Cleaning the cache of messengers and social networks

WhatsApp, TelegramViber are the main devours of free memory on Xiaomi smartphones, and these apps store every photo, video, and voice message they receive into local storage, creating giant archives in months of active correspondence.

The most effective way to clean up is to use built-in memory management within the applications themselves. Telegram needs to go to Settings → Data and Memory → Memory Use and click Clear Cache. It is important that this action does not delete your correspondence, as it is stored on a cloud server, and the media files will be re-uploaded if necessary.

For WhatsApp, the procedure is a little more complicated: go to Settings → Data and Storage → Storage Management. Here you will see a list of chats sorted by volume, you can selectively remove heavy attachments from specific dialogs without deleting the history of the correspondence itself.

Done: 0 / 1

Remember that social networks like Instagram and TikTok also accumulate a huge amount of temporary data. In the settings of the Android application (Settings → Apps → All apps), you can find the Clear cache item, which will safely delete temporary data without leaving your account.

Manually cleaning folders in the file manager also yields results, but requires caution. Android/media and Android/data folders can contain application data, deleting which will cause resets of program settings.

Media files make up most of user data, and optimizing them gives the most noticeable gain in free space.Redmi’s modern smartphone cameras take high-resolution shots, each of which can weigh between 3 and 10 megabytes, and 4K video recordings take up even more.

The first step is to revisit the Screenshots and Downloads folder, which often stores images that you only needed once, and use the Recycle Bin feature in the gallery to permanently delete files, freeing up space for good.

To store your photo archive, you can use cloud services like Google Photos or Xiaomi Cloud. Activate the Free Space feature in the Google Photos app, which will remove photos and videos that have already been safely stored in the cloud.

Then use the "Free space" feature in the menu."> Synced with the cloud allows you to store thousands of photos without taking up a single byte of internal memory of the phone, but to work offline, you will need to manually select albums for local storage. It’s also worth checking the Recently Deleted folder, as the files are stored there for 30 days and continue to take up space. ⚠️ Attention: Deleting photos from the cloud can sync and delete them from the device, so always check your sync settings before mass cleaning.Apps and games removal Many users install games and apps "just in case," forgetting them for months. Not only do these programs take up space, they can also run in the background, using up Redmi 9 processor resources. Regularly auditing installed software is a must. Go to Settings menu → Apps → All apps and sort the list by size. You will be surprised to find games with a cache of 2-3 GB that have not been played in six months. Removing such heavyweights is the fastest way to get free space. Pay attention to the preinstalled Xiaomi and Google apps that you don't use. Although system applications are difficult to remove, many of them can be disabled or Remove the real-liferated resources, you only want to re-run it, but you do it in the next time you don't use it, but you't use it to re-upload it to re-run it, but you don't use it, but you't use it to re-run it, but you't use it to re-run it, but you't use it, you're going to re-upload it to download it. An alternative to completely removing apps can be to transfer apps to a memory card if your Redmi model is a real one. 9 The map is formatted as internal storage, although Android is not always willing to transfer data to the Internet. SD-Download folder is a black hole where all the files from the Internet get to: documents, installers, images from browsers. Browsers by default save everything there, and over time, digital debris accumulates there. Open the Explorer or Files app and go to Downloads. Sort files by date or size. Delete everything. APK-files, as after installing the program they are no longer needed, as well as old ones PDF-Documents and archives. It's also worth checking the folders of specific browsers, such as, Chrome/Downloads or UCDownloads. Often there are videos that you have watched once, or music tracks. 💡Regular manual check of the Download folder once a month prevents uncontrolled storage proliferation and keeps the system running fast. Be sure to clear up your download history in the browsers themselves and YouTube cache if you watch videos through the app, as it caches the videos you watched for quick rewinding. System debris, such as error logs and temporary update files, can be removed through the Recovery menu, but this requires deeper knowledge. If software methods do not give the desired result, it is worth considering hardware memory expansion. the Redmi 9 smartphone is equipped with a microSD card slot that allows you to transfer photos, videos and music there. When you install a memory card, the system will suggest using it as a portable storage device or as part of internal memory, and choosing the option "as internal storage" will allow you to move applications there, but the card will only work with this phone after formatting. Another radical but effective method is a factory reset, which will return the phone to a store-like state by removing all the accumulated garbage, remnants of remote applications and system hash debris. Before resetting, be sure to back up your data through a Google Account or app. MIUI After resetting, you will get a clean system with maximum free memory. ⚠️ Warning: Hard Reset permanently deletes all data from your phone, including contacts and messages, if not stored in the cloud or on the phone. SIM-map. Use of the USB-OTG It also allows you to temporarily recycle large amounts of data for viewing or storage, freeing up the internal memory of the device. Why does the memory fill up even if I don't download anything? This is due to background processes, app caching (such as social media feeds) and system logs, and application updates can take up extra time space. Is it safe to delete files from your Android folder? Delete files inside your folder Android/data and Android/obb Deleting these files will reset the settings of the relevant games and applications or force them to download data again. 9? It is optimal to perform a surface cleaning once a week and a deep revision of files once a month. This will prevent critical memory filling and maintain high speed interface. Can crowded memory damage the phone? Critical space shortage (less than 100 MB) can lead to cyclical reboots, inability to receive calls and messages, and damage to the system database.
