How to accelerate Xiaomi Redmi 7A to maximum speed: the complete guide

Xiaomi Redmi 7A is one of the most popular budget smartphones, but over time even it starts to β€œbrake” and β€œhang”. The reasons can be different from clogged memory to outdated firmware. In this article, we will discuss 10 proven ways to speed up your Redmi 7A without buying a new phone. All methods are suitable for MIUI 12/13/14 and do not require root rights (except for one exception, which we will discuss separately).

It's important to understand that the Redmi 7A is equipped with a Qualcomm Snapdragon 439 processor and 2 GB of RAM are the minimum specs for modern applications, but even with these limitations, you can achieve smooth operation if you configure the system correctly. Let's start with the simplest ways and get to "heavy artillery".

1.Cache and garbage cleanup: the first step to speed

The most common cause of brakes is filled memory. MIUI uses cache to speed up work, but over time it turns into a dump of unnecessary files. On Redmi 7A with its modest 16/32 GB of storage, this is especially critical.

How to clean the cache correctly:

  • πŸ“± Manually through settings: go to Settings β†’ Annexes β†’ App management, select any application and click "Clear Cache." Repeat for all commonly used programs.
  • 🧹 Autocleaning: in Settings β†’ Click β€œClean” – the system will find unnecessary files (including the remnants of remote applications).
  • πŸ”„ Cleaning through Safe Mode: If the phone brakes heavily, reboot it in Safe Mode (click the power button) β†’ Β«Reboot in Safe Mode) and clear the cache from there – this will delete even those files that are blocked in normal mode.

Tip: Do not clear the cache of system applications (for example, Google Play Services or MIUI System) - this can lead to failures.

πŸ’‘

If you clean the cache, it takes longer for the applications to load, that's OK. The cache speeds up the re-start, but the overload slows down the system.

2. MIUI optimization: disabling unnecessary functions

MIUI is not only a beautiful shell, but also a lot of background processes that eat up resources. On the Redmi 7A with its 2 GB of RAM, every megabyte counts. Here's what you can safely disable:

  • 🎨 Animations and transitions: go to Settings β†’ The phone. β†’ Version. MIUI (Click 7 times to activate Developer Mode, then to Settings β†’ Additionally. β†’ For developers and set: The scale of the animation window β†’ Disable Transition Animation Scale β†’ Disable the duration of the animator β†’ Shut down.
  • πŸ“‘ Auto-update MIUI: In Settings β†’ The phone. β†’ Update system disable "Automatic download updates." They take up space and brake in the background.
  • πŸ” Search by device: in Settings β†’ Search disable β€œShow results from apps” – this will speed up the opening of the search bar.

Warning: Do not disable Google Play Services or MIUI Optimization, which may disrupt the system, and do not change the animator Duration settings to values above 1x, otherwise the interface will become even slower.

πŸ“Š How often do you clean your Xiaomi cache?
Once a week.
Once a month
Only when the phone is slowing down.
Never clean.

3. Application management: what can be removed and what can be frozen

Redmi 7A has a lot of Xiaomi and Google apps that run in the background and eat up RAM, which you can't delete completely without root rights, but you can turn them off or freeze them.

List of safe applications to disable:

AnnexCan I remove it?What's the blackout gonna do?
Mi Video❌ (systemic)Free up ~50MB of memory and reduce background activity
Mi Music❌ (systemic)Stop downloading album covers in the background
Google Play Books/Moviesβœ… (remove)Remove unnecessary updates and notifications
Cleaner (Purifier)❌ (systemic)It slows down the system, but shutting it down is not recommended.

How to disable system applications:

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Select an unneeded app (such as Mi Video).
  3. Click β€œDisable” (if the button is inactive, the application is critical to the system).
What happens if you turn off the cleaner?
The Cleaner app is responsible for automatically optimizing the memory in MIUI, and shutting it down can cause the system to stop shutting down the background processes, making the phone even more braked, and it's better to leave it on, but manually clean the cache.

For advanced users, if you have root rights, you can use Titanium Backup or SD Maid to completely remove system applications, but on Redmi 7A, it's risky, because you have a good chance of getting a brick.

4.Setting up the autoboot: why the phone brakes after turning on

One of the main reasons for slow work is the autoload of applications when you turn on your phone, and many programs (especially messengers and social networks) are added to the autoboot and immediately after the system starts, they begin to consume resources.

How to manage autoload:

  • πŸš€ Through settings MIUI: Go to Settings. β†’ Annexes β†’ Application management β†’ Autoboot. Turn off autorun for all applications except critical ones (e.g. Phone or Messages).
  • πŸ›‘ Through ADB (without root: connect your phone to your PC, turn on Debugging USB and execute the command: adb shell pm disable-user --user 0 com.miui.weather2 (substitute com.miui.weather2 packet).

Critical information: Redmi 7A cannot disable autoboot for system services with com.android. or com.miui packages. - This will lead to a reboot cycle.

5. Optimizing RAM: How to make 2 GB work more efficiently

Two gigabytes of RAM is very little for Android 10/11, which runs Redmi 7A. But there are ways to make the system use RAM more rationally:

  • πŸ”„ Swap setting: If you have a microSD card installed, you can create a swap file. You need root rights and Swapper for Root. Risk: writing to a card frequently reduces its lifespan.
  • ⚑ Limitation of background processes: C Settings β†’ For developers, set Process Limit to a maximum of 2 background processes, which will force you to close unnecessary applications.
  • πŸ“‰ Use lighter versions of apps: replace Facebook with Facebook Lite, Messenger with Messenger Lite, and Chrome with Chrome Lite (Basil.

Comparison table of "heavy" and "light" applications:

Normal appendixLight versionSaving RAM
FacebookFacebook Lite~150MB
MessengerMessenger Lite~200MB
ChromeBasil (Chrome Lite)~100MB

Warning: Do not install memory optimizers from Google Play (such as Clean Master or DU Speed Booster) that consume resources themselves and often contain ads that further slow down the system.

6. Update firmware: whether to switch to custom assemblies

The official updates to the Redmi 7A have long since stopped β€” the latest stable version of MIUI 12.5 based on Android 10.

  • πŸ”„ Official firmware: check the current version in Settings β†’ The phone. β†’ System Update: Sometimes Xiaomi releases security patches that optimize performance.
  • πŸ› οΈ Custom firmware: LineageOS 17.1 (Android 10) or Havoc-OS (Android 11) are free of garbageΒ» MIUI Cons: loss of warranty, risk of bricking, possible bugs with the camera or sensors.
  • βš™οΈ Cores and Modifications: Firmware on the FrancoKernel or ElementalX kernel can improve performance by 10-15%, but requires root and experience.

Warning: Before you install custom software, be sure to unlock the bootloader through the Mi Unlock Tool (the process takes 7-14 days due to Xiaomi restrictions). TWRP β€” Without it, data recovery is not possible.

πŸ’‘

Custom firmware gives you performance gains, but it requires technical skills, and for beginners, it's better to limit yourself to optimizing standard MIUI.

7 Hardware Methods: When Software Optimization Does Not Help

If all of the above methods failed, the problem could be in the hardware. For the Redmi 7A, the typical "iron" causes of the brakes:

  • πŸ”‹ Worn-out battery: When the battery is degraded below 70% capacity, the phone begins to artificially limit performance. Check the battery status via ##4636## (Menu "Battery InformationΒ»).
  • πŸ”₯ Overheating: Snapdragon 439 is prone to trottling (automatic frequency reduction) when heated above 60Β°C. Clean your phone of dust and replace the heat paste (at the service center).
  • πŸ’Ύ Damaged Memory: If your phone is slowing down while writing files, check the health of your flash memory through DiskInfo (an app from the Play Market.

Tip: If you decide to replace the battery, take the original battery BYD or Sunwoda (article: MB123 for Redmi 7A).

8.Extreme measures: reset to factory settings

If none of the methods worked, it's a hard reset, which will delete all the data, but it will return the phone to factory speed.

  1. Create a backup of important data (contacts, photos, messages) through Mi Cloud or Google Account.
  2. Go to Settings β†’ About Phone β†’ Resetting β†’ Delete all data.
  3. Select β€œClean Everything” and wait for the reboot (it will take 5-10 minutes).
  4. After resetting, do not restore data from the backup immediately – first check the speed of the clean system.

Important: Redmi 7A can reset the IMEI if you have previously changed firmware or received root. To restore the IMEI, you will need an engineering menu (#3646633##) and an NV-data file.

What to do if the phone does not turn on after reset?
If after a hard reset, the Redmi 7A stuck on the logo or went into the bootloop, try: 1. Go to Recovery Mode (Power + Vol Up) and repeat the reset. 2. Swipe the phone through the Fastboot with official firmware (instructions on en.miui.com). 3. If nothing helps, carry to the service (possibly damaged memory).
