How to make your phone faster: speeding up Redmi 9A

Owning a budget smartphone such as Redmi 9Aoften involves the need for constant optimization. This model, based on a processor Helio G25 and an operating system Android 10 with a shell MIUIhas modest hardware resources. Over time, cache buildup, background processes, and heavy application updates can cause noticeable performance degradation. However, there are many software methods that can significantly improve the interface response and device speed without replacing hardware.

In this guide, we will look at effective ways to make your phone faster using built-in system tools and third-party utilities. You will learn which settings MIUI should be changed first, how to properly manage RAM, and why standard cleaning methods do not always work. Proper configuration will extend the life of the gadget and make its use more comfortable even in 2026.

Before taking radical measures, it is worth assessing the current state of the system. Often the problem lies not in the age of the device, but in incorrectly configured parameters or storage overload. Let's step by step through all the stages of optimization to get the most out of your Xiaomi Redmi 9A.

Analysis and freeing up internal storage

The first and most critical factor affecting the speed of any Android smartphone is the fullness of the internal memory. When the free space drops below 10-15%, the system starts to slow down due to file fragmentation and lack of space for temporary files. Owners Redmi 9A with a memory capacity of 32 or 64 GB should especially carefully monitor this indicator.

First, you need to remove unused applications. Go to Settings → Applications → Application management and carefully study the list. Often there you can find heavy games or apps that you have not used for months. Removing such applications not only frees up space, but also removes background services that consume processor resources.

Particular attention should be paid to instant messengers, such as Telegram or WhatsApp. These apps tend to accumulate gigabytes of media files that are automatically saved to the device's memory. Clearing the cache within the applications themselves or transferring media files to external storage can free up to several gigabytes.

Why does memory affect speed?

Low free memory forces the memory controller to work in intensive defragmentation mode, which creates additional load on the processor and increases the system response time when writing new data.

Use built-in application Security from Xiaomi. Despite the presence of advertising, this tool effectively finds the remains of uninstalled apps and large files. Regular cleaning through this tool is basic hygiene for a budget smartphone.

• 🗑️ Delete all applications that you have not used in the last 3 months.
• 📸 Transfer photos and videos to your computer or cloud storage.
• 🧹 Clear your browser and social cache networks through application settings.
• 📂 Use the file manager to search for files larger than 100 MB.

⚠️ Attention: When clearing memory through third-party cleaner applications, be careful. Some of them can aggressively unload processes, which will cause them to restart and drain even more battery. It is better to use the built-in system tools.

Optimization of the MIUI interface and animations

The shell MIUI is known for its visual design, but the abundance of animations can create the illusion of slow work on the processor. Helio G25. You can speed up the visual response through the hidden developer menu. This will not increase actual processing power, but will make switching between screens instant.

To activate the developer menu, go to Settings → About phone and quickly click on version seven times MIUI. After the message “You have become a developer” appears, return to the main settings menu and find the item Advanced → For developers. Here we are interested in the animation scaling parameters.

Find the settings: "Window Animation", "Transition Animation" and "Animation Duration". By default they are set to 1x. Change them to 0.5x or disable them completely (0x). This action will instantly remove delays when opening folders and launching applications, making the interface more responsive.

It is also worth disabling or minimizing the use of live wallpapers. They consume significant GPU and RAM resources. Replacing a dynamic background with a static high-resolution image is an easy way to reduce the load on the system.

In the "For Developers" section you can also find limiting background processes. Setting a limit of, for example, 2-3 processes will prevent many sleeping applications from accumulating in memory. However, be careful: limiting it too aggressively can break the functionality of instant messengers and notifications.

• 🚀 Reduce animation scale to 0.5x for instant response.
• 🖼️ Replace live wallpaper with a static image.
• 🛑 Limit the number of background processes in the menu developer.
• 🌙 Use a dark theme if you have an AMOLED screen (to save money), although on the IPS Redmi 9A this is just a matter of habit.

Managing startup and background processes

One of the main reasons for slowdowns Redmi 9A is excessive application activity in the background. Many apps tend to start along with the system and remain active, consuming RAM and processor cycles. Control over startup is a key stage of optimization.

In new versions MIUI startup management is integrated into the battery settings. Go to Settings → Applications → Autorun. Here you will see a list of applications that start with the phone. Leave enabled only those from which you need instant notifications (for example, instant messengers), feel free to disable the rest.

In addition, you can configure a battery saving strategy for each application. Go to Settings → Battery & Performance → Energy Saver. For rarely used applications, select Limit background activity or Freeze mode. This will prevent them from running when you're not using them.

⚠️ Note: Don't limit background activity for Google system services, security apps, and important messengers if you want to receive notifications on time. Changes take effect immediately, but may require a reboot to be fully applied.

It is also useful to periodically check the list of running applications. With 2 GB of RAM, multitasking is limited. The habit of closing unused applications by swiping up from the recent tasks menu will help free up RAM for the current task. Redmi 9A With 2GB of RAM, multitasking is limited. The habit of closing unused applications by swiping up from the recent tasks menu will help free up RAM for the current task.

Application type	Recommended status	Impact on RAM	Impact on battery
Messengers (WhatsApp, Telegram)	Autostart ON, No restrictions	Medium	High
Social networks (VK, Instagram)	Autoplay OFF, Limited	High	Very high
Games	Autostart OFF, Freeze	High (at startup)	Medium
Banking applications	Autostart OFF, Limited	Low	Low
System services	Do not touch	Critical	Critical

Disable advertising and system notifications

Advertising in shell MIUI (MSA - MIUI System Ads) is not only annoying, but also consumes Internet traffic and processor resources to load advertising modules. Disabling advertising is an important step towards speeding up the interface and increasing privacy.

The most effective way is to disable the service msa. Go to Settings → Passwords and security → Access to personal data. Find the service in the list msa and turn off the switch. The system will ask you to wait 10 seconds, after which you need to click “Recall”. If it doesn’t work the first time, repeat the procedure 3-5 times.

You should also disable personalized advertising in your account settings Xiaomi and in the app store GetApps. This will reduce the number of pop-ups and background activity of advertising SDKs built into system applications.

Do not forget to disable notifications from unnecessary applications. Each pop-up notification is a micro-awakening of the screen and processor. Go through the list of notifications and leave only the really important ones.

• 🚫 Revoke access to personal data for the service msa.
• 📉 Disable ad personalization in your account settings.
• 🔕 Block notifications for games and stores.
• 🧹 Clear recommendations in folders on the desktop (folder settings).

Reset settings and radical measures

If software optimization does not give the desired result, perform a full factory reset. This is a drastic method that removes all user data, apps and settings, returning the phone to its out-of-the-box state. Often after such a reset, Redmi 9A starts working much faster.

Before performing a reset, be sure to create a backup copy of your important data. Use the cloud Xiaomi Cloud, Google Drive or transfer files to your computer. After the reset, you will need to re-enter your account passwords and set up your phone.

To perform a reset, go to Settings → About phone → Reset settings → Erase all data. The process will take a few minutes, after which the phone will reboot. For the first 15-20 minutes, the system will index files and update components, so a little sluggishness is possible during this time.

⚠️ Attention: Before resetting, make sure that the battery charge is at least 50-60%. Interrupting the reset process due to a low battery may damage the system partition and make it impossible to boot the OS.

An alternative to a full reset is to update the firmware to the latest available version. Developers Xiaomi periodically release patches that optimize the system. Check for updates in the menu About phone → MIUI version.

Additional operating tips

In addition to software settings, there are general operating rules, compliance with which will help maintain high operating speed Redmi 9A. Budget processors are sensitive to overheating: as temperatures rise, the system automatically reduces frequencies to prevent damage, which leads to lag.

Try not to use the phone while charging, especially for heavy tasks. Also, do not keep the device in direct sunlight. Using a lightweight case instead of a massive protected case can improve heat dissipation.

Is it worth installing launchers?

Third-party launchers (Nova, Lawnchair) may be lighter than the standard one, but on weak devices they sometimes create conflicts with MIUI system optimization. Try it, but be prepared to roll back the changes.

Regularly rebooting your phone (every 2-3 days) is also useful. It clears RAM of errors and terminates frozen processes that may have accumulated during operation.

• 🌡️ Monitor the case temperature, avoid overheating.
• 🔄 Reboot your smartphone every few days.
• 📱 Do not use heavy widgets on your desktop table.
• 🔋 Avoid using the phone while fast charging.

Frequently asked questions (FAQ)

Will installing a third-party antivirus help speed up Redmi 9A?
