How to Clean Xiaomi Redmi 8T Phone: The Complete Guide

Xiaomi Redmi 8T, launched in 2019, is still a popular device due to its excellent price-performance ratio. However, over time, any Android gadget starts to run slower and memory space disappears rapidly, a natural process of accumulating system debris, app cache and temporary files that requires regular user intervention.

Proper cleaning of the device allows not only to free up gigabytes for new photos and videos, but also to significantly extend the battery life. In this article, we will detail safe optimization methods that will return your Redmi 8T to its former speed without having to reset to factory settings.

Memory Occupancy Analysis and Hidden Files Search

Before we start taking any drastic measures, we need to understand what is taking up precious space. The MIUI shell on Redmi 8T has a powerful analytics tool built in, which is often ignored by ordinary users, and allows you to visualize the distribution of data and identify hidden folders that inflate the system.

Go to Settings → Memory or run the standard Security app and select Cleanup. The system will scan and show an approximate amount of garbage being removed. However, the automatic analyzer does not always see large files downloaded from messengers or browsers.

• 📁 Check the Download folder – there are often installations. APK-files that are no longer needed.
• 📸 Analyze the gallery for duplicates and blurry images taking up space.
• 💬 Pay attention to the cache of Telegram and WhatsApp, which can grow to several gigabytes.

⚠️ Note: Before removing files from the root directory or system folders, make sure they are not required for installed applications to work. MIUI.

You can use a built-in file manager for deep analysis. Open it, click on the three dots menu, and select Analyzer. This tool will show you the largest files on the device, allowing you to quickly decide whether to delete them. Often users forget about downloaded TV shows or old navigation maps, which weigh a lot.

Cleaning the cache of applications and system debris

Cache is temporary data that apps save to speed up their work. Over time, these files can get corrupted or simply take up an unreasonable amount of space. On Xiaomi Redmi 8T, cache cleaning is a secure procedure that does not delete your logins, passwords or correspondence.

For manual cleaning, go to Settings → Apps → All Apps. Select the most “heavy” app (like YouTube, Instagram or Chrome browser) and click Clear → Clear Cache. Don’t confuse this button with the “Clear All” feature, which will reset the app to the state immediately after installation.

System debris, including remnants of remote programs and temporary update logs, should be removed through the regular Security application. Run the scan and press the clean button. This action will make room, but will not affect the user's personal data.

• 🧹 Clean your browser cache regularly if you actively use web surfing.
• 🗑️ Delete the map cache (Google Maps, Yandex.Maps) if you are not using offline navigation right now.
• 🔄 Periodically clean the Play Market store cache if there are errors when downloading updates.

It is important to understand the difference between cache and app data. If you clear the data, for example, Instagram will have to re-enter the password, and games may lose progress if it is not stored in the cloud. Always read the system warnings carefully before confirming an action.

Optimization of messengers: Telegram and WhatsApp

Messengers are the main memory eaters on modern smartphones. Telegram and WhatsApp by default store all received photos and videos in the memory of the device. On Redmi 8T with its limited amount of internal storage, this becomes a critical factor.

Telegram handles the situation most elegantly thanks to the cloud nature of the messenger. Go to Settings → Data and memory → Memory Use. Here you will see the option “Storage media”. Set a value of 3 days or 1 week. Also click the button “Clear Telegram cache” – this will safely delete downloaded files from the phone, but leave them available in the chat when you reopen.

WhatsApp is more complicated because the database is stored locally, and you need to go to Settings → Data and Storage → Storage Management, where you can delete files larger than 5 MB or clear specific chats, and you should also turn off auto-save to the gallery:

Settings → Chats → Save in “Photo albums” → Turn off

Regularly reviewing media files in messengers keeps the system on track, and many users have been storing postcards and voice messages for years that have no value but take up hundreds of megabytes.

⚠️ Note: When cleaning the WhatsApp database through the file manager (folder) Android/media/com.whatsapp) You may lose the ability to restore backup chats. Use only built-in cleaning tools inside the application.

Removal of duplicates and work with the gallery

Photos and videos make up the lion's share of user data. On the Xiaomi Redmi 8T, the screen has a resolution of 1080 x 2340 pixels, which means even short videos can weigh a significant number of megabytes. Duplicates often occur when sync failures or reboot from the cloud.

Use the Google Photos app or the built-in MIUI gallery to find similar images. Google Photos has a Free Space feature that removes from your device those images that are already stored in your cloud account, one of the most effective ways to quickly gain free space.

Remember the Recycle Bin folder in the gallery, because the deleted photos don't disappear immediately, they're stored there for 30 days, and they're still in space, and to clear up your memory, you go to the Deleted album and select Clear Everything.

If you take a lot of high-resolution pictures, it makes sense to change the camera settings. For shooting and posting on social networks, 12 MP resolution is often enough instead of the maximum, which will significantly reduce the weight of files without visible loss of quality on the smartphone screen.

Removal of unused applications and services

Redmi 8T has a lot of apps that you may never use, called bloatware, and although it's hard to remove system applications without root permissions, user software needs to be ruthlessly removed if it's not in use.

Go to Settings → Apps → All apps. Sort the list by size or frequency of use. If you see a game you haven't played in six months or a food delivery service you don't use, delete it. Even if the app isn't running, it can contain background services and update, consuming resources.

Special attention should be paid to games. Modern mobile games can weigh 2-4 GB or more. If you passed a game or abandoned it, releasing this amount of memory will give the system a huge boost in performance. The Snapdragon 665 processor installed in the Redmi 8T will thank you for that.

• 🚫 Remove old versions of apps if you still have a copy of the installer when you update (APK).
• 🛑 Disable or remove unnecessary widgets on the desktop, they consume RAM.
• 📉 Watch out for apps with active geolocation access, they plant the battery and write logs.

For advanced users, there is the option of removing system debris via ADB (Android Debug Bridge), but this requires a computer connection and certain knowledge.

Using Developer Mode and Resetting Settings

If standard methods don't work and the phone is slow, you can try deeper optimization methods. There are settings in the developer menu that affect the visual speed of the interface. To activate the menu, you need to click on the MIUI version 7 times in the About Phone section.

In the open menu Additional → For developers, find the Drawing section. Change the scale of the window animation, transition and duration of the animator to 0.5x. It won’t cleanse your memory physically, but it will visually do the work of Redmi. 8T more responsive and quick.

💡

Before performing a full reset, make sure to back up all important contacts and photos to Google Drive or computer, as all data will be irretrievably deleted.

The last resort is a factory reset, which will put the phone back into a store-like state, and make sure it has at least 50 percent battery power before charging it.

Settings → About the phone → Reset settings → Erase all data

⚠️ After resetting the settings on modern smartphones will work protection Google (FRP). You'll need to enter the username and password from the Google account that was tied to the phone before the reset!

After a reset, take your time to install all the applications at once. Watch the clean system work. Often the problem lies in one particular application that conflicts with the system. Install the software gradually to identify the culprit.

💡

Regular prophylaxis (once a month) takes 5 minutes, but eliminates the need to do a complete system reset once a year.
