How to speed up Xiaomi Redmi 9C: effective optimization methods

Xiaomi Redmi 9C is deservedly considered one of the most affordable devices on the market, but its budget stuffing can raise questions about performance over time. Users often notice slowing down the interface, long application launches and periodic slowdowns in games. This is a natural process for the MediaTek Helio G35 processor and the MIUI shell, which consumes significant system resources.

Fortunately, there are a number of proven methods to significantly extend the comfort of your gadget without replacing the device itself. Competent visual effects tuning, background control and system debris cleaning can work wonders. In this guide, we will look at a comprehensive approach to speeding up your device.

Before we start taking any radical steps, it's important to understand that optimization is a balance between functionality and speed. Some improvements will require giving up some of the visual beauty, but the result is worth it. Let's take a look at the basic steps that need to be done first.

Cleaning and management of internal memory

The most common reason for the slowdown of Xiaomi Redmi 9C When the space is empty, the system has no place to place temporary files and cache, which leads to a sharp drop in response speed. 15-20% total.

Start by analyzing what takes up the most space. With MIUI, you can quickly identify heavyweights. Go to Settings → Memory and evaluate the situation. Often, instant messengers that accumulate gigabytes of media and streaming services are the main consumers.

Use the standard Security for Auto Cleaning app. Despite criticism of built-in cleaners, in the Xiaomi ecosystem, they work most correctly, removing system debris, not important user data.

For a deeper cleanup, manually go through folders with uploaded files. Pay attention to DCIM, Download and social media cache folders. Deleting old screenshots, unnecessary videos and APK installation files can free up a few gigabytes.

• 🗑️ Remove unused apps that you haven’t run for more than a month.
• 📸 Transfer photos and videos to a memory card SD or cloud storage.
• 💬 Clear the cache in the Telegram and WhatsApp app settings (Settings) → Data and storage).
• 📂 Remove files from Download folder, leaving only current documents.

It's important to understand that the constant filling of memory leads to fragmentation of data, which is especially critical for the type of eMMC memory installed in this model, and regular file system hygiene is a guarantee of stability.

💡

Use the Cleanup function in the Security app once a week to keep the system in good shape.

Optimization of MIUI interface and animations

The MIUI shell is famous for its beautiful yet heavy-duty interface. For a budget Helio G35 processor, rendering complex animations can be a time-consuming task. Accelerating the system is often achieved by reducing visual effects, making the interface more responsive.

The first step is to activate the developer mode. To do this, go to Settings → About Phone and quickly click on the MIUI version 7 times. Once the message "You became a developer" appears, you will access the hidden settings.

Next, go to Settings → Advanced Settings → For developers. Find the section related to animation scaling. You need three options: "Window animation", "transition animation" and "Animation duration". Set 0.5x or completely disable them (Without animation).

⚠️ Warning: Disabling animations completely can make the interface less intuitive, as smooth transitions between screens will disappear. 0.5x.

It’s also worth turning off Memory Extension if it’s active by default, which should help in theory, but on slow memory cards or when you’re working with a lot of applications, it can instead cause micro-freezes because of the low speed of virtual paging.

• 🚀 Reduce the scale of animations to 0.5x developer-menu.
• 🔋 Turn off "Memory Extension" in the settings if you notice jerks of the interface.
• 🌙 Use a dark theme to reduce the load on the screen and processor when rendering.
• 📱 Remove unnecessary widgets from the desktop, they consume RAM.

Another important thing is the live wallpaper, which not only lands the battery, but also uses the GPU resources all the time, and replacing them with a static image is an easy way to reduce the load on the system.

Managing Autoboot and Background Processes

Many applications in MIUI aim to run alongside the system and continue to run in the background, consuming precious RAM. Autoboot control is a key step in the optimization of the Xiaomi Redmi 9C.

In the Settings → Apps → Autoboot menu, you will see a list of programs that start with your phone. Leave here only what you really need to receive instantly (such as instant messengers). Social networks, games and stores should be removed from this list.

Also, you should set the limits for background activity. Go to Settings → Battery and Performance. Select Balance or Energy Saving mode. No-limit mode makes the processor run at high frequencies all the time, leading to trottling (reduced frequency due to heat) and brakes.

For each heavy application, you can customize the restrictions. → App management select the program you want, go to the Battery, and select Background Activity Limitation, which will prevent it from working when you're not using it.

Remember to reboot your smartphone periodically. Reboot clears the RAM from "stuck" processes and resets errors in the work of system services. Do this at least once every 2-3 days.

Disabling Advertising and System Services

One of the features MIUI It's a built-in advertisement (MSA — MIUI System Ads. Not only is it annoying, it uses Internet feed and CPU time to load ad units. Disabling ads is a must-have step to speed up the speed.

To turn off MSA, go to Settings → Passwords & Security → Access to data. Search the msa list and turn off the slider. The system will ask you to wait 10 seconds, then press "Disable." If the first time failed, repeat the procedure several times.

You should also disable personalized recommendations. Go to Settings → Passwords & Security → Privacy → Advertising Services and disable Personalized Ads. This will reduce the amount of data collected about you and the load on the network.

Xiaomi's built-in apps that you don't use (e.g. Mi Video, Mi Music, Browser) are also better off deaktivirovat or uninstall updates if the system doesn't allow them to be removed completely.

• 🚫 Disable the msa service in the data access settings.
• 🔒 Prohibit personalization of advertising in privacy settings.
• 📲 Remove or freeze unnecessary system applications.
• 🌐 Turn off automatic app updates in Google Play and GetApps.

⚠️ Note: Complete removal of system applications through ADB Removing critical components can lead to a cyclical reboot).

💡

Disabling MSA advertising services is the most effective way to reduce background load on the processor and network.

Special features and Game Turbo

For gamers and users who want maximum performance in specific tasks, MIUI has Game Turbo mode, which redistributes CPU resources in favor of running the game, blocks notifications and clears memory.

Add your games to the Safety → Game Turbo app. Inside the Game Turbo settings, select a performance profile. For older games, you can choose Balanced Mode, for heavy ones, Performance Mode, but watch for heating.

There is also a hidden feature in special features that can help. In the Settings menu → Advanced Settings → Special features you can find settings to improve visibility, which sometimes affect the rendering of text, making it clearer, which is subjectively perceived as improving performance.

Do not abuse third-party "accelerators" from Google Play. They often work on the principle of "kill process", killing the processes that the system immediately starts again, creating an extra load on the CPU. MIUI fairly.

Radical measures: Resetting and reflashing

If the software methods didn't work, it might have accumulated errors or conflicts after a lot of updates, and then a full factory reset helps.

Before you reset, make sure to back up all your important data via Mi Cloud or Google Account. Go to Settings → About Phone → Reset → Erase all data. This will put your phone back out of the box.

After reset, don't restore all applications immediately through a backup. You'd better install only the essentials manually. Often, old cache files and setting conflicts are transferred along with the backup, negating the reset effect.

For advanced users, custom firmware (like LineageOS or Pixel Experience) can be installed, which completely removes the heavy shell of MIUI, leaving pure Android. However, for the Redmi 9C, this can be risky due to the specifics of the MediaTek processor and can lead to loss of warranty or camera inoperability.

If the reset doesn’t work, the problem may be hardware, such as flash memory wear or processor overheating, and software optimization is no longer effective.
