Xiaomi Redmi 7 is one of the most popular budget smartphones, but even it begins to “slow down” over time due to full memory. If your phone is running slower, apps are closing suddenly, and the “Memory is full” notification appears too often, it’s time to act. In this article we will look all possible ways to clear memory on Redmi 7, from basic to advanced, taking into account the features of the firmware MIUI and hardware limitations of the model.

It is important to understand: clearing memory is not only about deleting unnecessary files. This is a set of measures that includes optimizing the cache, transferring data to a memory card, managing background processes, and even resetting settings in extreme cases. We will not advise to “just delete everything” - instead you will get detailed instructions with explanationswhy this or that method works (or does not work) specifically Redmi 7.

Let's get started! Let's start with the safest methods and gradually move on to more radical measures. If you are not sure of your actions, do not skip the blocks with warnings (highlighted with the ⚠️ icon). They will help you avoid typical mistakes that users make when clearing memory on Xiaomi.

1. Analysis of full memory: what is taking up space on Redmi 7?

Before deleting something, you need to understand which files occupying your memory Redmi 7. There is a built-in analysis tool, but it does not always show the full picture. Here's how to use it correctly: MIUI There is a built-in analysis tool, but it does not always show the full picture. Here's how to use it correctly:

  1. Open Settings → About phone → Memory.
  2. Wait for scanning to complete (may take up to 1 minute).
  3. Press to a category (for example, "Applications" or "Media files") to see details.

Typical “memory card” on Redmi 7 looks like this:

Category Average volume (32 GB) Can it be cleaned?
System files 8–12 GB No (reset only)
Applications 5–15 GB Partial (delete, transfer)
Application cache 1–4 GB Yes (completely)
Media files (photos, videos) 3–10 GB Yes (transfer, delete)
Other files (downloads, documents) 1–5 GB Yes (manual cleaning)

Please note: if the "System files" partition takes up more than 15 GB it is a sign that the firmware MIUI has become bloated due to updates or errors. In this case, only resetting to factory settings will help (more on this in section 6).

⚠️ Attention: On Redmi 7 with 32 GB of memory, the system can show “full” even with 25–28 GB of occupied space. This is due to the fact that part of the memory is reserved for the needs of Android and MIUI. Do not try to fill the memory to capacity - leave at least 3-4 GB free for stable operation.

      • ❌ The card cannot be removed without losing data.
      • ⚠️ The speed of the phone may decrease if the card is slow (lower class UHS-I).
      How to format the card as internal memory?

      1. Insert the card into the phone.

      2. Go to Settings → Memory → SD card.

      3. Click "Format as internal" (all data on the card will be deleted!).
