How to completely clear the cache on Xiaomi Redmi 8 Pro: system, applications and Dalvik

Xiaomi Redmi 8 Pro is a popular smartphone with performance hardware, but even it eventually begins to “brake”. One of the main reasons is clogged cache, which takes up precious memory and slows down the system. Unlike flagship models, budget devices like Redmi 8 Pro have a limited amount of internal memory (64/128 GB), so cleaning the cache is especially relevant here.

In this article, we will discuss all the ways to remove cache on Xiaomi Redmi 8 Pro, from standard MIUI tools to hidden features for power users. You will learn how to clean the cache of individual applications, the system cache (including Dalvik), and what to do if the smartphone after cleaning began to work even worse.

Why Xiaomi Redmi 8 Pro cache should be cleaned regularly

Cache is a temporary file that creates apps and a system to make things faster, for example, when you open Instagram or YouTube, some of the data (miniatures, tapes, settings) is stored in the cache so that the next time you run the content loads faster, but over time these files accumulate and lead to:

• 🐢 Slowdown – the system spends resources on processing unnecessary data.
• 📉 Lack of memory – cache can take 5-15 GB on Redmi 8 Pro (especially if you are actively using social networks and instant messengers).
• 🔄 Application crashes – outdated cache files may conflict with updated versions of programs.
• 🔋 Fast battery discharge - background cache cleaning consumes charge.

On the Redmi 8 Pro, the problem is compounded by the fact that the smartphone is equipped with eMMC memory (rather than faster UFS), which over time degrades with frequent recordings / deletions, so regular cleaning of the cache not only frees up space, but also prolongs the life of the drive.
