How to Clean Memory on Xiaomi Redmi 7A Phone: The Complete Guide

Xiaomi Redmi 7A is one of the most popular budget smartphones of the brand, but its 16 or 32 GB of internal memory is quickly clogged with photos, applications and system debris. If your phone starts to slow down, give notifications about space shortages or spontaneously close programs, it’s time to clean up. In this article, we will discuss all the working ways to free up memory on the Redmi 7A — from basic to radical, taking into account the features of the MIUI firmware and the hardware limitations of the model.

It's important to understand that Redmi 7A runs on a Qualcomm Snapdragon 439 processor and has only 2 GB of RAM, which means that even with free storage space on the drive, the phone can slow down due to file fragmentation or overloaded cache, and we'll not only show you how to delete unnecessary data, but also explain why some methods work better than others for this model.

1. Analysis of occupied space: what exactly eats memory?

Before you start cleaning, you need to know which files are taking up the most space, and on Redmi 7A, you can do this in two ways:

• 📊 Through embedded tools MIUI: Go to Settings. → The phone. → Memory: Here, the system will show the distribution of memory by category (applications, multimedia, cache, etc.).
• 🔍 Using third-party analyzers: applications like Files by Google or SD Maids give more detailed breakdown, including hidden files.

Typical memory eaters on Redmi 7A:

Redmi 7A is particularly quick to clog the "/data" section, where user data is stored. If less than 1 GB is free, the phone starts to reset background processes, which leads to app crashes.

⚠️ Note: Do not manually delete files from folders /system or /vendor — This can cause the phone to lose its performance and require flashing.

2.Cleaning App Cache: A Quick Way to Free 1–3 GB

Cache is a temporary file that apps create to speed up work. On Redmi 7A, cache can take up to 5 GB, especially if you are actively using social networks, messengers or games.

• 🗑️ For all applications at once: Settings → Warehouse → Clear the cache (button at the bottom of the screen).

After clearing the cache, some apps (like YouTube or Google Maps) can load longer on the first run - that's normal.

Reboot your phone to apply changes

Check the work of critical applications (banks, instant messengers)

Disable Auto Cleaning for Frequently Used Programs

Backup of important data (in case of failures)-->

• 📸 Compress existing photos: use Google Photos (Free Place option) or Resizer (Play Market).
• 🎥 Change the camera settings: in Redmi 7A Default is 12 MP resolution – reduce to 8 MP in camera settings → Permission.

7. Additional Tips for Optimizing Redmi 7A

To make your memory clog slower, follow these guidelines:

• 🔄 Turn off auto-update apps in the Play Market (or limit updates to Wi-Fi only).
• 📵 Limit background activity for unnecessary apps: Settings → Battery and productivity → Battery management → Choice of applications.
• 🗑️ Clean up downloads regularly: folder /Download often contains unnecessary APK and media files.
• 🛡️ Use easy alternatives to popular programs: - Instead of Chrome - Chrome Lite or Opera Mini - Instead of Facebook - Hermit Lite or the web version - Instead of Instagram - Instagram Lite
• 🔋 Watch for battery health: A worn-out battery can cause sudden reboots, resulting in file system damage.

For advanced users:

Install custom recovery (such as TWRP) and clean the Dalvik Cache and Cache sections regularly.

Disable the system animation via ADB (speed up work):

adb shell settings put global window_animation_scale 0.5


adb shell settings put global transition_animation_scale 0.5




adb shell settings put global animator_duration_scale 0.5
