Cache Clearing on Xiaomi Redmi 8T: 5 Ways to Free Memory and Speed Up Your Smartphone

Xiaomi Redmi 8T is a popular smartphone with a balance of price and performance, but over time even it begins to slow down. One of the main reasons is crowded cache. These are temporary files that applications and the system create to speed up work, but over time they take up gigabytes of memory and, conversely, slow down the device. In this article, we will discuss all the current ways to clean the cache on Redmi 8T, including hidden MIUI functions and safe methods for beginners.

Itโ€™s important to understand that there are two types of cache โ€“ application cache (deleted without consequences) and Dalvik cache (system cache, requires caution), we will show you how to clean both types without risking data, and you will learn why Redmi 8T with MIUI 12+ cache takes up to 5-7 GB even in standard use โ€“ this is a feature of firmware that can be fixed.

1. Clear cache through MIUI settings (the safest way)

This method is suitable for beginners and does not require superuser rights. It only deletes unnecessary temporary files without affecting personal data. On Redmi 8T with MIUI 10-14, the path to cleanup is the same, but new versions have added additional options.

How to clean:

  • ๐Ÿ“ฑ Open the Settings. โ†’ Annexes โ†’ Application management.
  • ๐Ÿ” In the upper right corner, click on three dots and select Sort by size โ€“ so you will see the most โ€œgluttonousโ€ programs.

2.Use of the built-in MIUI cleaner

MIUI has its own optimization tool, the Security App, which not only cleans the cache, but also removes junk files, remnants of deleted applications and duplicate photos. On Redmi 8T, it works more efficiently than third-party cleaners because it has access to system folders.

Step-by-step:

  • ๐Ÿš€ Click Clean and confirm the action.

๐Ÿ”น Tip: In the Autoclean section, you can set up automatic cache deletion once a week, which is useful if you install/remove applications often. 8T With 32GB of memory, autoclean sometimes deletes files from the Download folder โ€“ check its contents after the procedure.

Once a week | Once a month | Only when the phone brakes | Never cleaned | I don't know what it is

3. Clean Dalvik cache via Recovery (for power users)

Dalvik cache is a system file created by the Android virtual machine to speed up application launches. On Redmi 8T, it can take up to 1-2 GB and is not cleared through standard settings. Deletion is safe, but requires rebooting to Recovery mode.

On Redmi 8T, this is especially critical, because it is almost impossible to recover information without a backup. If you accidentally press the wrong button, turn off the phone right away - sometimes it helps interrupt the process.

4. Third-party applications for cleaning the cache

FAQ: Frequent questions about cleaning cache on Xiaomi Redmi 8T

๐Ÿ”น Why After Cleaning the Cache, Applications Boot Longer?
This is normal: cache speeds up the re-launch of applications. Once cleaned, they create new temporary files, which takes time. After 1-2 days, the speed will return to normal. Except for games (such as PUBG Mobile), which can load resources longer.
๐Ÿ”น Can the cache be cleared for a specific system application (e.g., MiuiHome)?
Yes, but be careful. Use it for system applications. ADB-command: adb shell pm clear com.miui.home After that, the launcher will reboot and all widgets and wallpaper will be reset. 8T This can cause the Launcher Stopped error โ€“ just restart your phone.
๐Ÿ”น How much space should be freed up after cleaning the cache?
Depends on the use: ๐Ÿ“ฑ Standard use (social networks, messengers): 1โ€“3 GB. ๐ŸŽฎ Game Profile (Genshin Impact, Call of Duty): 4โ€“8 GB. ๐Ÿ“ท Photo (many photos in Google Photos): 10 GB (due to thumbnail cache) If it's free <500 MB โ€“ the cache was already clean or the applications quickly recovered the files.
๐Ÿ”น Why on Redmi? 8T cache quickly fills up again?
The culprits: Facebook and Instagram โ€” cache videos and stories (up to 500 MB/day); Google Play Services โ€” updates maps and services in the background. MIUI automatically backs up /MIUI/backup (you can turn off in Settings โ†’ Additional โ†’ Backup). Solution: Limit background activity in Settings โ†’ Battery โ†’ Power Saving Mode.
๐Ÿ”น Can I turn off the caching completely?
Technically, yes, but it's highly discouraged: ๐Ÿ“‰ Applications will be loaded 2-3 times longer. ๐Ÿ”‹ Battery consumption will increase by 15-20% (constant data reboot). ๐Ÿ“ถ Mobile traffic will grow (apps will download data again). Alternative: use Greenify to freeze unnecessary apps.
