How to Clean Xiaomi Redmi Phone Memory: The Complete Guide

Owners of Xiaomi and Redmi devices sooner or later face an unpleasant situation: the phone starts to run slower, applications fly out, and notifications of space shortage appear with alarming regularity. Internal memory is the most valuable resource of a smartphone, and its overflow directly affects the stability of the MIUI or HyperOS operating system. When the storage is clogged, the system simply has nowhere to place temporary files for the correct operation of processes.

Freeing up space on Xiaomi Redmi requires a comprehensive approach, because simply removing a few photos is not enough. You need to analyze the storage structure, find hidden folders of garbage that have accumulated for years after remote applications, and correctly adjust synchronization. In this article, we will discuss proven cleaning methods that will help return your gadget to its previous speed.

Before we go into radical measures, it's important to understand what exactly takes up space, often not the apps themselves, but their cache and media in messengers, and if cleaned properly, it will save important data and free up gigabytes of space without losing the functionality of the device.

Analysis of the occupied space in settings

The first step to freeing up space is diagnostics, and the MIUI has a powerful analysis tool built in that users often ignore when relying on third-party software, but the built-in analyzer sees system files better than any other. To get there, you open Settings and select Memory (or Storage) and the system instantly calculates how many gigabytes are occupied and how many are free.

In this section, you'll see a color diagram where each sector is responsible for a specific type of data: apps, images, videos, documents, or whatever. If you click on any of the sectors, you'll be taken to a detailed menu. For example, the Apps section will sort all the programs installed by size, which allows you to instantly identify the heavyweights you might have forgotten about, and it often turns out that games weigh 3-5 GB, and social networks have ballooned to unimaginable sizes.

⚠️ Warning: Be careful when analyzing the Others section, which may contain important database files or cache of maps, deleting which will result in loss of saved progress or offline navigation.

Special attention should be paid to the MIUI folder, which often grows due to system logs and temporary update files. Although the system periodically cleans them, manual control is never superfluous. If you see that the Other category takes up more than 10-15 GB, this is a signal to deeper check the file system through the explorer.

Use of the built-in "Security" application

Every Xiaomi smartphone has a Security system app preinstalled, and it's not just an antivirus, it's a powerful harvester to optimize. The app icon is usually green with a shield. When you run it and select Cleanup, you start scanning the system for temporary files, residual files and cache ads.

Once the scan is complete, the system will suggest removing the debris found. However, if you click on the Clean button right away, you will miss the option of fine-tuning it. It is recommended to click on the Clean up the garbage button (or similar), but before the final confirmation go through categories. For example, in the Cache section you can see what is most occupied by YouTube or Instagram. You can selectively clear the cache of these applications without touching the others.

There's also a Deep Clean section in the Security app, which looks for similar images, old APK installation files, and unnecessary packages, and it's more aggressive than standard cleaning, and you can find WhatsApp videos that have been viewed once and forgotten, and removing them is safe for the system to work, but critical for freeing up space.

Clearing the cache and data messengers

The most voracious apps on any Android smartphone, including Redmi, are messengers: Telegram, WhatsApp, Viber. They store every photo, video and voice message you see in your phone's memory. Over time, these folders can grow to tens of gigabytes. Just delete the app and put it back in again is an option, but there's a more elegant way.

Telegram itself, for example, has a built-in cache cleanup feature that doesn't delete your correspondence, but erases downloaded media files from the device. They will only reload when you reopen the chat. Go to Settings → Data and memory → Memory Use and click Clear Cache. You can also set up autodelete files that haven't opened for more than a week.

• 📱 WhatsApp: Go to Settings → Data and storage → Storage management.You can delete files larger than 5MB here or clear the chat rooms that take up the most space.
• ✈️ Telegram: Use the Cache feature in the settings to delete temporary files, leaving the option to re-download.
• 💬 Viber: In the settings, select Memory → Clear the memory. Pay attention to the gallery section, where duplicates are often found.

⚠️ Attention: Clearing the data (no cache!) in the settings of the messenger applications will result in a complete logout and deletion of correspondence if no backup is made. Be careful when choosing between Clear cache and Erase data».

In addition, the MIUI file manager often contains an Android/media folder, which can also contain heavy files from messengers even after they have been cleared from the applications, and checking this directory through Explorer (a standard file manager) will help you find forgotten video files.

Removal of duplicates and large files

Over the years of using a smartphone, the gallery inevitably accumulates hundreds of identical photos taken in serial mode, or screenshots that are no longer relevant. Manually sorting through thousands of files is an ungrateful task. Fortunately, the Xiaomi gallery has a smart album that groups similar images.

Open the Gallery app, go to the Albums tab, and scroll down to the Similar Photos section (or search for Screenshots). The system will prompt you to delete blurred frames or duplicates, leaving only the best option. It's an easy way to free up a few hundred megabytes in a couple of minutes.

It’s also worth checking the Download folder. Browsers and apps often save installation files there, PDF-So many people forget about this place until it's full, and sorting files by size in the Explorer will help you quickly find and delete forgotten video files or archives.

Transferring data to the cloud and external media

If Xiaomi Redmi’s internal memory is physically limited (e.g. 64 or 128 GB), then the only way out is to transfer data. Modern smartphones rarely support memory cards, so cloud storage is becoming the standard. Google Photos allows you to store images in a compressed but high-quality format for free (with limitations) or in original quality through a subscription.

Turn on sync in the Google Photos app or Xiaomi Gallery (Mi Cloud). Once you make sure that copies are saved in the cloud, you can use the “Free Space” feature in the Google Photos app itself, which will remove from your phone those pictures that are already safely on the server.

For transferring large amounts of data (movies, archives of work) it is convenient to use OTG-If you buy a Type-C adapter, you can copy heavy files to an external drive and delete them from your phone, which is especially true before you upgrade when you need a lot of free space.

💡

Use the Clear Source Files function in cloud services only after double checking the availability of photos in the cloud from another device (for example, from a computer).

Radical Methods: Resetting and Formatting

When software methods fail and the memory fills up on its own even after cleaning, there may be errors or broken sectors in the file system, in which case formatting helps. Be sure to make a full backup of important data before doing so.

The most effective method is a full factory reset, which will put the phone back into a store-like state. Go to Settings → Phone → Settings → Reset → Erase all data. It will take about 10-15 minutes. Once turned on, the phone will be completely clean.

⚠️ Warning: Full reset deletes ALL data, including contacts, SMS, photos and accounts. Make sure your Google account is synced and important files are copied to your computer or to the cloud.

There's also a less radical method, which is to clean through Recovery Mode, and by pressing Volume+ and Power when the phone is off, you can go to the recovery menu, and you can select Wipe Data, which is the analog of resetting through settings, but sometimes it helps if the system doesn't boot normally.

💡

Regular prevention (once a month) takes less time than emergency cleaning of a crowded storage facility.

After reset, don't be in a hurry to install all the apps at once. Try using a clean phone for a couple of days. Often it turns out that half the installed software you don't need, and you won't clog up your memory again.
