How to Clean Xiaomi Redmi 7A: From Cache to Deep Optimization

Xiaomi Redmi 7A smartphone is getting slower over the years, even if you haven't installed new apps, and it's caused by the accumulation of garbage in the system: temporary files, residual data from remote programs, crowded cache and fragmented memory. But don't rush to buy a new gadget! With proper cleaning, the performance of the device can be returned to its original level, and in some cases even improved.

In this article, we will discuss all ways to clean Redmi. 7A — From basic (deleting cache and unnecessary files) to advanced (reset to factory settings with data storage). MIUI, You will also learn what actions can irreversibly damage the system and how to avoid them.

Why Xiaomi Redmi 7A is slowing down and needs cleaning

The Redmi 7A’s main problem is limited hardware resources: just 2GB of RAM and 16/32GB of memory, and over time, even these modest capacities are clogged:

• 📱 Application cache – temporary files that should speed up the operation of programs, but when accumulating take up gigabytes of memory.
• 🗑️ Residual data – “tails” from remote applications that remain in the system and interfere with its operation.
• 🔄 Memory fragmentation – files are scattered throughout the drive, which makes the smartphone reads them longer.
• 🤖 Background processes MIUI — Xiaomi’s operating shell is actively using resources for analytics and updates.

The tests show that after a year of use, the Redmi 7A loses up to 30-40% of its performance due to debris, with a physical wear of no more than 5-10% of its iron (processor, memory), meaning that 90% of brake problems are solved by software cleaning, not by replacing components.

⚠️ Warning: Don't confuse memory cleaning with defragmentation. On smartphones with eMMC (like Redmi) 7A) Not only is defragmentation useless, it also shortens the life of the drive. Use only the methods described in this article.

Preparation for cleaning: what to do before you start

Before you start cleaning, follow a few mandatory steps:

1. Back up. Even if you plan on just cleaning the cache, errors happen. Use the built-in Backup app (Settings → System & Device → Backup) or third-party services like Google Drive.
2. If you plan to make a deep cleaning (for example, reset to factory settings), make sure that the charge is at least 50%.
3. Disable your Mi Account. Go to Settings → Xiaomi account and temporarily log out of your profile. This will prevent the device from being locked after a reset.

We also recommend connecting your smartphone to Wi-Fi – some cleaning methods require you to download additional data (such as updating your firmware after a reset).If you have limited traffic, turn off automatic update downloads in Settings → About Phone → System Update.

Basic cleaning: removing cache and debris without root

Start with the safest methods that don’t require superuser rights and don’t risk data.

1. Cleaning up the app cache

Cache is a temporary file that applications create to speed things up, and over time, it takes up gigabytes of memory to clear the cache.

1. Go to Settings → Applications → Application Management.
2. Select an app (such as YouTube or Facebook).
3. Press Warehouse. → Clear the cache.

For mass cleaning, use the built-in Cleanup utility (Settings → Cleanup) that analyzes the system and suggests removing unnecessary files, including:

• 🗑️ Cash app.
• 📁 Temporary download files
• 🎵 Empty folders and duplicates

2. manually delete unnecessary files

Open the Files app (or any file manager) and check the following folders:

• 📂 Download – Download files you haven’t opened in a long time.
• 📂 DCIM/.thumbnails — Photo and video miniatures (can be removed without consequences).
• 📂 Android/obb — game data (e.g. cache) PUBG Mobile or Genshin Impact can weigh a few gigabytes).

Pay special attention to the Android/data folder, which stores application data. Only delete folders that are remote programs. For example, if you have uninstalled TikTok for a long time, but the folder com.zhiliaoapp.musically remained, you can safely delete it.

💡

If you're not sure if you can delete a folder, transfer it to your computer or to the cloud, and if you don't have any problems in a week, delete it.

3. Clearing the history and data of the browser

Browsers (Chrome, MIUI Browser) accumulate gigabytes of data: history of visits, cookies, uploaded images.

1. Chrome: ⋮ → History → Clear the data.
2. V MIUI Browser: ⋮ → Settings → Confidentiality → Clear the data.

Select the "All Time" period and mark all items except "Passwords".

Deep cleaning: reset to factory settings

If the basic methods didn't work, it's time for a hard reset, which deletes all data, including apps, settings and files, returning the smartphone to the "out of the box" state. The Redmi 7A has two ways of resetting:

Method 1: Through the settings menu (recommended)

This method is safer because it allows you to save some data (for example, files on the computer). SD-map).

1. Go to Settings → About the phone → Reset settings.
2. Select to erase all data (reset to factory).
3. Enter the password (if installed) and confirm the action.

It takes 5-10 minutes, and after the restart, you'll be asked to set the phone up as new.

Method 2: Recovery Mode (if the phone is not turned on)

If your smartphone is stuck on the logo or does not respond to touch, use the recovery mode:

1. Turn off the phone (press Power + Volume up for 10 seconds).
2. Press Power + Volume up until the Mi logo appears.
3. In the Recovery menu, select Wipe Data → Wipe All Data (manage by volume buttons, confirm by power button).

After the reset, the phone will restart. If this does not happen, remove the battery for 30 seconds (you will need to disassemble the case).

⚠️ Attention: On Redmi 7A Recovery reset deletes all data, including files on internal memory. If you have enabled the function "Storage as internal" for SD-The card will also be formatted. Before reset, remove the memory card!

💡

Resetting to factory settings is the most effective way to get performance back, but it requires a complete reinstallation of apps and settings. Use it only if other methods have failed.

Optimization after cleaning: how to maintain speed

Once cleaned, the Redmi 7A will run faster, but without the right setup, the speed will drop again in a few weeks.

1. Turn off the autoloading of applications

Many programs run when you turn on your phone and run in the background, consuming memory, to turn off autoboot:

1. Go to Settings → Applications → Application Management.
2. Select an app (like Facebook or AliExpress).
3. Press Autostart and turn off the option.

For mass shutdown, use the Greenify app (requires permission for special access in battery settings).

2. Set up a performance mode

MIUI has a hidden mode that limits the background processes:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers.
3. Turn on the options: 🔧 Do not save actions (reduces the use of RAM). 🔧 Limit background processes (select process maximum 2). 🔧 Disable window animation (accelerates the interface).

3. Move the applications to SD-map

If you have a microSD installed, transfer some applications to it:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as WhatsApp).
3. Press Warehouse. → Change. → SD-map.

Alternative ways to accelerate the Redmi 7A

If the cleaning didn’t produce the desired result, try these methods:

1. Firmware update

Xiaomi regularly releases updates to optimize the performance of older models, to check the relevance of the firmware:

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, install it.

For Redmi 7A, the latest official firmware is MIUI 12.5 based on Android 10. Updates to Android 11/12 will not be, as the hardware does not support new versions.

2. Use of lightweight versions of applications

Replace the "heavy" programs with their lightweight counterparts:

• 📱 Facebook Lite instead of Facebook (savings) ~200MB of RAM).
• 📷 Instagram Lite instead of the standard Instagram.
• 🎵 YouTube Go instead of YouTube (allows you to download videos for offline viewing).
• 💬 Messenger Lite instead of the main Messenger.

3. disabling unnecessary MIUI functions

The MIUI shell consumes a lot of resources because of the background.

• 📊 Analytics. MIUI: Settings → Memory. → ⋮ → Settings → Delete "Recommendations".
• 📡 Auto-Update Apps: Play Market → ⋮ → Settings → Auto-update → Never.
• 🔍 Search for Mi apps: Settings → Home screen → Search for applications → Shut down.

💡

Lightweight versions of applications and disabling MIUI background processes can increase battery life by 15-20% and speed up program opening by 30-40%.
