How to clean Xiaomi Redmi 7 from garbage: speed up the smartphone

Xiaomi’s Redmi series has been well-deservedly popular for years due to its excellent price-to-function ratio. The 2019 Redmi 7 is still in active use with millions of users worldwide. However, like any Android device, the phone begins to accumulate digital garbage over time, leading to slowdowns, slowdowns in applications and rapid battery consumption.

The accumulation of temporary files, remnants of deleted programs and messenger cache is a natural process of using the gadget. The MIUI system installed on Redmi 7 has its own features of working with memory that differ from pure Android. The user often does not notice how gigabytes of useful space turn into useless ballast. In this article, we will analyze proven methods of safe cleaning that will help return the device to its former sharpness.

It's important to understand that simple cleaning with standard tools doesn't always produce the desired result. Deep cleaning requires a comprehensive approach, from storage analysis to manual removal of system logs. We'll look at both the built-in MIUI tools and more advanced methods available to the power user.

Memory Occupancy Analysis and Hidden Files Search

Before you start taking drastic action, you need to make a thorough diagnosis of what exactly occupies space on your Redmi 7. The standard notion that memory is filled with only photos is often mistaken. The bulk of the volume can be taken up by social media cache, which grows to several gigabytes, and forgotten downloads in the Download folder.

To start with, you should use the built-in analyzer. Go to Settings → Memory. This will provide a visualization of the data distribution. Pay attention to the "Other" category. Often, this is where files that the system cannot classify, but which occupy a significant amount of volume, are hidden. Also, check the MIUI → gallery → cloud folder, where deleted photos can be stored, waiting for final cleanup.

⚠️ Note: Before removing files from the folder Android/data Make sure they don’t contain game saves or important app settings.Blindly removing the contents of this directory can cause game progress to reset.

Analysis shows that users often ignore offline maps and music loaded by streaming services, which can take up to 30% of all memory, and regularly reviewing the content of the library helps keep the system in good shape.

Use of the built-in "Security" application

The MIUI shell preloads a powerful system application called Security, which is the primary tool for quickly cleaning Redmi 7 from surface debris, and it can find temporary files, remnants of APK installation packages and advertising debris, and it takes less than a minute to run the scan, but its effectiveness depends on regular use.

For deep cleaning, open the app and select Clean up. The system will prompt you to delete files larger than 20 MB, duplicates and large videos. However, be careful with the Acceleration feature, which forcibly closes background processes. On Redmi 7, with its RAM capacity, aggressively shutting down applications can lead to them being rebooted, which will only increase battery consumption.

In the Security settings, you can activate automatic cleaning, which will allow the system to delete temporary files on its own when a certain occupancy threshold is reached, and it is recommended to set a limit of 85% occupancy, so that there is always room for the system to work properly.

It’s worth noting that the built-in scanner doesn’t always see the cache of some specific apps, such as TikTok or Instagram. They require manual verification through specific program settings or using specialized utilities. The built-in tools are good for daily maintenance, but not for general cleaning.

Manual cleaning of messenger cache and social networks

The most voracious apps on any Android smartphone, including Redmi 7, are instant messengers. WhatsApp, Telegram and Viber store every image, video and voice message received in the memory of the device. Over time, the database of these applications can grow to 10-15 GB, which is critical for models with a small amount of built-in storage.

Telegram cleansing is the most flexible. Go to Settings → Data and memory → Memory usage: You can set a cache limit (e.g. 500MB) or clear it completely with the Clear Cache button, and it's important that this action doesn't delete your correspondence, the files will simply be re-downloaded from the cloud if necessary. WhatsApp is more complicated: you need to go to Settings. → Data and storage → Storage management and selectively delete large files.

Social media sites like VKontakte or Instagram also accumulate huge amounts of data. Viewing the feed forms a massive cache of images and videos. You can clean it up through the application management menu: Settings → Apps → All Apps → [Select App] → Memory → Clear the cache. Don't confuse it with the "Clean All" button, which will reset the login.

⚠️ Note: When cleaning up messenger data, make sure you have an up-to-date backup of your correspondence in the cloud (Google Drive or iCloud) if your chat history is important to you.

Regularly checking these four categories of applications should become a habit, and they are the main culprits of space shortages, and automating this process through the settings of the applications themselves helps to forget about the problem for a long time.

Removal of system debris and residual files

When apps are removed, they often have tails on the system — folders with logs, temporary configurations, and data that have not been deleted automatically. On Redmi 7, these files can lie for years.

Note folders with names of remote games or programs at the root of internal memory. It is also worth checking the Android/obb directory. If you deleted a game with heavy graphics data, the folder with its name can stay there and take 1-2 GB. Manually find and delete these orphaned folders.

Another source of debris is the.thumbnails folder in the DCIM directory, which stores thumbnails of all images viewed. The.thumbnails file can weigh hundreds of megabytes. It can be safely deleted, but it will be recreated the next time you open the gallery. For a temporary solution, you can create a text file with the same name and prevent the system from overwriting it, although new versions of MIUI do not always work.

System debugging logs can also take up space, especially if you’ve once connected your phone to a computer to debug over USB. Cleaning these logs is secure and is done through developer menus or specialized software-cliners if you have root rights, though Redmi 7 is better off without superuser rights to avoid losing warranty and stability.

Cleaning up uploads and duplicate photos

Download is a black hole in most users' memory. Browsers, instant messengers, and app stores store APK installation files, PDF documents, and pictures there. Often users forget they downloaded a file a week ago, and it continues to lie dead.

Go to the file manager and sort the contents of the Download folder by date. All files older than a month that are not important documents can be safely deleted. Pay special attention to files with the.apk extension. Once you install the application, this file is no longer needed, storing it is a waste of resources.

Photo duplicates are another common problem: they occur when you re-save images from messengers or sync failures. Use smart albums in the gallery or third-party apps to find takes. On Redmi 7, with its screen and camera, photos can weigh a little, but they number in the thousands, which adds up to gigabytes.

💡

Tip: Set up automatic cleaning of the download folder in your Chrome browser. Go to Settings → Downloaded files and enable deletion of files older than 30 days.

Remember the gallery cart. Deleted photos don't disappear immediately, they go to a cart that's stored for 30 days. If you deleted the photo wrongly and want to make room right now, don't forget to clear that section.

Resetting settings as a radical cleaning method

If the software cleaning doesn’t work and the Redmi 7 continues to slow down, there may be critical registry errors or conflicting files in the system, in which case the (most effective) method is a full reset to the factory settings (Hard Reset), which will put the phone back out of the box, removing all user debris, viruses and errors.

Before the procedure, make sure to back up your data to your computer or Google cloud. Reset will destroy all contacts, photos and apps. To perform the reset, go to Settings → About Phone → Reset → Erase all data. The phone will restart and begin the cleanup process, which can take 10-15 minutes.

After reset, take your time to install all the applications at once. Install them one by one and check the system. Often the cause of debris and brakes is one particular, poorly optimized application. Clean installation is a guaranteed way to extend the life of an aging device.

⚠️ Warning: Make sure the battery is at least 50% before reset, and better charge the phone to 100%. interruption of the reset process due to discharge can damage the system partition and the inability to turn on the phone.

💡

Full reset is the only way to remove 100% of the garbage and system errors, but it requires prior backup of all the important data.

Remember that after the reset, the system will update in the background, which can temporarily reduce performance. Give the phone an hour or two of quiet work with Wi-Fi on to complete all background optimization processes.

Prevention and healthy habits

To avoid wondering how to clean up Xiaomi Redmi 7 garbage every month, you should develop useful digital habits. Regularity is the key to a clean system. Once a week, take 5 minutes to check the download folder and messenger cache.

Use cloud storage for photos and videos. Services like Google Photos or Yandex.Disk can automatically upload media files to the cloud and delete them from your phone’s memory, freeing up gigabytes of space. For Redmi 7, with its limited memory, this is a critical feature.

Avoid installing accelerators and antiviruses from unverified sources. Often, these applications are themselves a source of advertising and garbage, consuming processor and battery resources, and the built-in MIUI and common sense when installing programs is enough for security.
