Cache Clearing on Xiaomi Redmi Note 7: A Complete Guide to MIUI 10/11/12

The Xiaomi Redmi Note 7 is still a popular smartphone even after years, thanks to its balanced performance and support for MIUI updates. However, over time, many users face slowdowns, overheating and memory shortages. The main reason is a clogged cache that takes up gigabytes of space and slows down the system. Unlike the new models, the Redmi Note 7 has a limited 32/64 GB of memory, so cleaning the cache here is critical.

In this article, you will find 5 proven ways to clean up cache, from standard MIUI tools to hidden features for power users. We will examine which cache can be removed without risk and which should not be touched so as not to break applications. You will also learn how to automate the process and avoid re-clogging memory.

Why Redmi Note 7 cache should be cleaned regularly

Cache is a temporary file that creates applications and a system to make things faster, like when you open Instagram, it saves thumbnails of photos so that it can show them faster the next time you run them, and the problem is that over time, these files accumulate and:

• 📉 Slow down the smartphone — MIUI Starts to “hang” when switching between applications.
• 🔥 Overheating – the processor spends resources on processing unnecessary data.
• 🚫 Block updates – memory shortages may interrupt installation of new versions MIUI.
• 📱 Breaking apps – conflicts between outdated cache files and new versions of programs.

The Redmi Note 7 is particularly critical to the cache of Google Play Services and MIUI System, which can take up to 3-5 GB in long-term use without cleaning, while standard deletion through Settings does not always help: some files remain in hidden folders.

⚠️ Warning: Don’t confuse cache with app data! Deleting cache is secure, and erasing data (such as in WhatsApp or games) will result in loss of progress and settings.
