Xiaomi Redmi 7 is still a popular budget smartphone, but its main drawback is only 32/64 GB of internal memory. Over time, the device begins to slow down, applications fly out, and the system warns, โNot enough memoryโ, the reason is not only in the small amount of storage, but also in the automatic accumulation of garbage: app cache, temporary files, duplicate photos and remnants of deleted programs.
In this article, we have 7 proven ways to clean up memory on Redmi 7 without root rights and loss of important data. We will examine both standard MIUI tools and hidden features that are not written about in the official instructions. And you will learn which files can be deleted without risk and which cannot be touched categorically (spoiler: it is not only a DCIM folder).
1. The analysis of occupied memory: what exactly eats the place?
Before you clean, you need to understand which files take up the lion's share of memory. On Redmi 7, this is done through the built-in analyzer:
- Open the Settings โ Memory.
- Put it on the "Inner Memory" graph.
- Wait until the scan is completed (it can take up to 2 minutes).
The system will show the distribution by categories: Applications, Media Files, Cache, System Data and Other.
- ๐ฑ Applications: games of the type PUBG Mobile or Genshin Impact can weigh 2 to 5 GB each.
- ๐ธ Photo/video: Even after being removed from the gallery, they often remain in the folder MIUI/Camera/Recycle.
- ๐๏ธ Cash: Especially Telegram, VK and TikTok - can reach 1-3 GB.
- ๐ Remnants of Remote Programs: Folders in /Android/data/ and /Android/obb/.
If the System Data partition is >5 GB, it's a factory reset, which usually means file system fragmentation that can't be fixed manually.
2.Cache cleaning applications: safe and efficient
Cache is a temporary file that applications create to speed up work, and on Redmi 7, you can delete it in two ways:
Method 1: Through Application Settings
- Go to Settings โ Applications โ Application Management.
- Select an app (like YouTube or Chrome).
- Tap "Clear Cache." Don't click "Clear Data" - it will delete accounts and settings!
Method 2: Mass cleaning (hidden MIUI function)
Few people know, but MIUI has a tool to clean the cache of all applications at once:
- Open Settings โ Memory โ Cleaning.
- Click on โDeep Cleanโ (Print confirmation may be required).
- Select "Cash" and confirm the action.
This method frees up from 500 MB to 2 GB of memory, but has the nuance:
What happens after the mass cleaning of the cache?
Close all active applications
Connect charging (the process can take 3-5 minutes)
Do not interrupt the cleaning even if the screen goes out.
After cleaning, restart the phone.
-->
3. manually delete unnecessary files
Even after the cache is cleared, there are still invisible files in memory, which can be found and deleted through the built-in file manager or third-party applications like Files by Google.
Which folders to clean first of all
| folder | What it keeps. | Can I remove it? | Potential savings |
|---|---|---|---|
| /DCIM/.thumbnails | Photo and video miniatures | Yeah, totally. | 100-500 MB |
| /Android/data/ | Data from remote applications | Yes, but not all (see below) | 500MB - 3GB |
| /MIUI/Camera/Recycle | Deleted photos (basket) | Yeah, unless you need files. | up to 10GB |
| /Download/ | Uploaded files (APK, PDF, ZIP) | Yes, except for important documents. | 1-5 GB |
| /Android/obb/ | Additional game data | Only if the game is deleted | 1โ2 GB per game |
Attention! /Android/data/ stores game saves and app settings. Only delete folders that are already remote, for example, if you have uninstalled Facebook long ago, but the com.facebook.katana folder is still there, you can clean it.
