How to speed up Xiaomi Redmi 9A: The Complete Guide

The Redmi 9A budget smartphone has been a well-deserved hit thanks to its excellent price-to-quality ratio, but over time, even the most reliable device can start to work slower. It is a natural process caused by the accumulation of system debris, updating applications and increased demands on hardware resources. Owners often notice delays when opening menus, twitching the interface and long responses to touch, which significantly reduces the comfort of use.

Fortunately, Android and MIUI have a lot of hidden features to fine-tune your performance, and you don't have to be a programmer to activate those features and get your device back to speed, and smart optimization allows you to extend your life without having to buy a new model.

In this article, we will detail the proven methods that will help resuscitate your smartphone. We will look at both standard cleaning tools and advanced developer settings available to every user. Reducing screen resolution to 720p is the most effective but invisible way to increase the FPS in the interface on the Helio G25 processor. Follow the instructions to get the most out of your device.

Analysis and release of internal storage

The first and most obvious reason for slowing down any smartphone is overcrowded memory. When free space on the system partition drops below 10-15%, the speed of writing and reading data critically decreases, which causes friezes. Android uses free space as a buffer zone for temporary files and cache, and without this reserve it begins to work in emergency mode.

Start by analyzing what exactly takes up space. Often users don’t even realize that messengers like Telegram or WhatsApp can take up several gigabytes to save all the videos and photos you’ve watched, and look at the Downloads folder, where APK installation files and unnecessary documents can lie for years.

For quick cleaning, use a built-in tool that is deeply integrated into the system and safe to remove system debris, it finds remnants of deleted applications, temporary files and advertising cache.

• 🗑️ Open the Security app and click on the Cleanup button to delete temporary files.
• 📂 Go to the storage settings and sort files by size to find heavyweights».
• 📸 Check the gallery for duplicate photos and videos in low resolution.
• 💬 In the settings of messengers, find the section “Data and storage” and clear the cache of media files.

⚠️ Warning: When using third-party cleaner software (Clean Master and analogues), be careful. They often become the source of advertising themselves and can aggressively unload the desired processes from memory, forcing the Redmi processor. 9A Work harder to re-start them.

Once the space is freed up, the system will have the necessary room to maneuver, which is not a panacea, but a fundamental step, without which further optimization may be useless. Regularly check the fullness of memory to maintain high speed.

Managing Autoboot and Background Processes

Many apps installed have a habit of running automatically when the phone is turned on and staying active in the background. For the budget MediaTek Helio G25 processor installed in the Redmi 9A, running a dozen background services simultaneously is a serious load that leads to trolling and lags.

There's a powerful tool in the MIUI shell to control boots that are often ignored, and turning off unnecessary programs here doesn't remove them, it just prevents you from starting with the system, and you can manually run them at any time, but they won't eat up RAM for nothing.

And you also have to pay attention to the memory extension feature, which, while it allows you to run more applications at the same time, using virtual memory (due to a slow flash drive) on budget devices often backfires. 10-15 heavy games, it is better to disable this feature so that the system works with fast physical RAM.

• 🚀 Go to Settings. → Annexes → All applications and forcibly stop unused services.
• 🛑 Turn off auto-start for social media and stores you don’t use every second.
• 📉 Consider disabling “Memory Extension” in the “Advanced Settings” section».

Control of processes is key to stability, and the fewer programs that try to outpace each other in CPU time, the smoother the interface works, especially for devices with 2 or 3 gigabytes of RAM.

Setup of animations and developer interface

One of the most effective ways to visually speed up the Xiaomi Redmi 9A is to scale up animations. By default, the system uses beautiful but long transitions between windows that create the illusion of smoothness but delay response. Cutting down animation time makes the interface twitchy but instantaneous.

To access these settings, you need to activate the developer mode, which is a hidden menu designed for engineers, but it's also useful for ordinary users, and don't be afraid to change these settings, because they're completely safe and reversible.

Once you activate the mode, find the section associated with rendering. You're interested in three things: the scale of the window animation, the scale of the transition animation, and the scale of the animator duration. Changing their value from 1x to 0.5x or completely shutting them down will give you a noticeable increase in speed.

Also on the developer menu, you can also look at the limitation of background processes, and you can tell the system how many apps can stay active. For Redmi 9A, the best option is “No background processes” or limiting it to 2-3 processes if you are actively using instant messengers.

The changes take effect instantly, and you'll notice that the phone is getting more responsive to touch, and it's a software turbo button that's available to every Xiaomi owner.

Disabling Advertising and System Notifications

MIUI is known for its aggressive monetization, which manifests itself in the form of advertising in system applications. Advertising modules (MSA - MIUI System Ads) consume Internet traffic, load the processor when loading banners and create unnecessary background data streams.

Not only will the ad turn off visual noise, it will also reduce the CPU load, and when the phone doesn't have to constantly poll advertiser servers and render banners in folders and conductor, it works faster, especially when the Internet connection is weak.

The process involves several steps, as the settings are scattered across different menus, first you need to find the MSA service and turn it off, and then go through system applications such as Explorer, Music, Themes and Security, removing the Receive Recommendations switches there.

• 🚫 Find the msa service in the list of applications and disable the slider "Get recommendations».
• 🔒 In the Security app, click on the gear and turn off "Get recommendations».
• 📁 In “Conductor” go to the settings and remove the tick from the item “Receive content».
• 🎵 In the “Themes” app in your profile also disable the display of ads.

⚠️ Attention: When you turn off msa, the system can show a countdown timer (10 seconds) and ask persistently for the reason. Just wait until the time ends and confirm the action.

Once these steps are done, the interface will be cleaner and the resource consumption of background services will decrease, a mandatory procedure for any Xiaomi owner who wants to improve performance.

Optimization of display and graphical acceleration

The screen is one of the most energy-intensive and resource-intensive components of a smartphone. 9A fixed IPS-resolution-matrix HD+, But the graphics chip may have difficulty rendering heavy interface elements. GPU It can have a positive impact on overall responsiveness.

In the developer settings there is an option to “Prohibit” HW-"Offset" (or "Offset layering"). Forced use GPU For all computations, it can speed up the interface, but it can also increase battery consumption. It works ambiguously for public sector workers, so it's worth testing individually.

It’s also worth considering reducing the refresh rate of the screen, if your model allows it (though for the sake of the model). 9A It's 60 Hz, which is the standard. The more important parameter is resolution. Some users practice density change. DPI (point-by-inch ADB-commands or special applications, but this can make fonts unreadable.

The best solution for the graphics part is to use the "Dark Theme". AMOLED-It saves energy on the screen, but even on the IPS-redmi matrices 9A Dark interface requires less processing power to render gradients and shadows, which can yield micro-performance gains.

Resetting and radical measures

If software optimization fails to deliver the desired results, the last and most effective method is a complete factory reset, and over time, registry errors, library conflicts, and data fragmentation accumulate in the system that cannot be removed by a simple cleaning, and resets the phone back out of the box.

Before this procedure, it is critical to back up all your data, reset will delete everything: contacts, photos, apps and settings, use the Mi Cloud or your computer to store important information, and make sure your phone is at least 60 percent charged.

You can start the reset process through the settings menu or through Recovery mode. The first way is simpler: Settings → About the phone → Resetting → Erase all data. The second way (via Recovery) is if the phone is not turned on or locked.

The sequence of actions for resetting through the menu:


1. Open "Settings."




2. Go to "About the Phone."




3. Select "Settings Reset."




4. Click "Erase all data."




5. Enter the unlock password and confirm the action.

Once reset, the phone will work as fast as possible, because it's a natural state. However, to keep this effect, don't install a hundred apps at once. Install only the necessary software and keep an eye on what gets into the boot.

💡

Hard Reset is the only way to completely eliminate software errors accumulated over the years of use, returning the speed of a new device.
