How to speed up Xiaomi Redmi 9A: proven methods without root

Xiaomi Redmi 9A is one of the most popular budget smartphones, but over time even it begins to “slow down”: applications open for a long time, animation twitches, and the system hangs when multitasking. The reason is not always in the “weak hardware” – more often to blame for the clogged memory, background processes and unoptimized settings of MIUI. In this article, we will discuss 7 working ways to speed up the Redmi 9A, from basic to advanced, without the risk of “bricking” the device.

It's important to understand that the Redmi 9A is equipped with a MediaTek Helio G25 processor and only 2/3 GB of RAM (depending on the version), which means that even after optimization, the smartphone will not “fly” like a flagship, but the right settings will return smoothness to the level of “out of the box”. We will not consider overclocking the processor or custom firmware — only safe and reversible methods.

1. Cleaning up memory and cache: the first step to speeding up

The most common reason for brakes is clogged memory. On the Redmi 9A with 32 GB of internal storage, there is often less than 5 GB of free space left, which is critical for the system to work. Start with basic cleaning:

• 📱 Remove unnecessary apps: Go to Settings → Annexes → Manage applications and sort by size. Remove games you don't use and junk utilities (like memory cleaners, which slow down the system themselves!).
• 🗑️ Clear the cache: Select an app from the same menu (like YouTube or Chrome) → Warehouse → Clear the cache. Use Settings for mass cleaning. → Warehouse → Clean up.
• 📂 Transfer files to a memory card: photos, videos and music can be moved to a microSD (if installed). MIUI highlight files → More. → Move it.

Pay special attention to the system cache, which does not delete personal data, but can release up to 1-3 GB:

1. Open the Settings → Storage.
2. Click on the Cache Data (bottom of the screen).
3. Confirm the cleanup. Once you restart, the system will create a new cache, but without any debris.

💡

If you clean the cache, the applications load for a long time on the first run, that's OK. The system recovers the necessary data.

2. Disconnect background processes and autoboot

MIUI aggressively keeps apps in the background, even if you don't use them, eating up RAM and battery power. On the Redmi 9A with 2-3 GB of RAM, every megabyte counts. Here's how to limit background activity:

• 🔄 Limit Autostart: Settings → Annexes → Application management → Autorun. Turn off autorun for all applications except instant messengers and system services.
• 🚫 Ban the work in the background: in the same application management menu, select the unnecessary application → Permits → Working in the background → Limit.
• ⏸️ Turn off notifications: many apps wake up to show notifications. Go to Settings → Notifications and disable unnecessary alerts.

You can manually close applications for radical acceleration, but this is a temporary solution.

1. Go to Settings. → The phone.
2. Click 7 times on the MIUI version to activate Developer Mode.
3. Back to Settings → Additionally. → For developers.
4. Find Process Limitation and select Process Maximum 2 in the background.

⚠️ Attention: limiting background processes to 2 may cause messengers (such as WhatsApp or Telegram) to receive messages slower.

3. Optimization of animation and MIUI interface

Animations and visuals make the interface look more beautiful, but weak devices slow down, and on the Redmi 9A, you can turn them off or speed them up, which will give you an increase in smoothness of up to 10-15%.

First, activate Developer Mode (as in the previous section), then:

1. Go to Settings. → Additionally. → For developers.
2. Find the items: Window animation scale → Set Off. or 0.5x. Transition animation scale → Off. or 0.5x. Animation duration → Off.

Reboot the phone.

The MIUI interface can be simplified:

• 🎨 Turn off wallpaper with effects: use static wallpaper instead of live (Settings) → Wallpaper).
• 🔍 Reduce the number of widgets on the home screen – they are constantly updated in the background.
• 📱 Switch to Light mode: Settings → Screen. → Display mode → Standard (instead of Saturated or Auto).

4. Resetting to factory settings: a radical solution

If previous methods didn’t work and the smartphone is still slowing down, it’s time to reset the settings. This will delete all data, but return the Redmi 9A to the “out of the box” state. Importantly, before reset, make sure to back up photos, contacts and messages through Settings → System → Backup.

Resetting instructions:

1. Open Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Enter the password (if installed) and confirm the action.
4. Wait until it is completed (it will take 5-10 minutes).

After discharge:

• 📱 Do not restore data from a backup right away – check the speed of a clean system first.
• 🔄 Install applications gradually, watching the performance.
• ⚠️ Don’t install “boosters” or “optimizers” – they will only make things worse.

⚠️ Note: if the phone still brakes after reset, the problem may be the wear and tear of the internal memory (especially if the device is more than 2-3 years old), in this case, only replacing the memory module in the service center will help.

5. Update of firmware and core: hidden reserves

Outdated firmware is one of the reasons for the brakes. Xiaomi regularly releases updates for the Redmi 9A, correcting errors and optimizing performance.

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, download and install it (preferably via Wi-Fi).

If automatic updates don’t help, you can try manual firmware through Recovery:

For manual installation:

1. Download the firmware for Redmi 9A (model dandelion) from the official website.
2. Move the.zip file to the root folder of internal memory.
3. Go to Settings → About Phone → System Update → Three Dots (menu) → Select a firmware file.
4. Select the downloaded file and confirm the installation.

⚠️ Note: Never install firmware from third-party sources (e.g., from 4PDA) Unofficial builds can contain viruses or unstable cores that will "kill" the phone.

6. Battery optimization and energy saving

Unexpectedly, power saving modes can both help and harm performance.On the Redmi 9A, improper battery settings often result in artificially limited CPU power.

Check the current parameters:

• 🔋 Turn off Ultra Mode: It severely limits performance. Go to Settings → Battery → Power saving mode and select Off or Balanced.
• ⚡ Set up battery optimization for individual applications: Settings → Battery → Battery optimization. For games and instant messengers, choose Unlimited.
• 📊 Check battery consumption: if any application consumes >10% in the background - limit his work (see section 2).

For maximum performance, you can turn off adaptive brightness and set a fixed value of 50-70%:

1. Settings → Screen → Brightness.
2. Turn off Adaptive Brightness.
3. Set the slider to a comfortable level.

💡

Performance mode in battery settings can increase speed by 5-10%, but reduce battery life by 15-20%. Use it only when necessary (for example, for games).

7.Alternative launchers and lightweight applications

The standard MIUI launcher is quite "heavy" for the Redmi 9A. It can be replaced with a lighter analogue, for example:

• 🚀 Nova Launcher is fast and customizable (free version is quite functional).
• ⚡ Lawnchair – a lightweight alternative with gesture support.
• 📱 Smart Launcher 5 – Optimized for weak devices.

Also replace the “heavy” applications with lighter versions:

For the installation of alternative launchers:

1. Download the selected launcher from Google Play.
2. After installation, click Home and select the new launcher as the main one.
3. Customize it for yourself (remove unnecessary widgets, turn off animations).

💡

Lightweight apps not only speed up work, but also reduce battery consumption, for example, Facebook Lite consumes 3 times less energy than the main application.
