How to speed up Xiaomi Redmi 9C: a complete guide to optimization

Xiaomi Redmi 9C is a popular budget device, but over time, even the nimblest gadget can start to slow down. Owners often face long application launches, interface lags and sudden system freezes. It is a natural process associated with the accumulation of software debris and the increased demands of modern applications for iron resources.

There are many effective ways to get your device back to speed without having to replace it. In this article, we’ll look at proven optimizations that can help extend your gadget’s life, and learn what hidden MIUI settings are worth changing to speed up the interface.

Don't go straight to the extremes of factory resets. Working with the file system and background processes can often be more secure and visible. Let's start by analyzing the current state of your Redmi 9C.

Cleaning internal memory and app cache

The first and most obvious reason for the slowdown is the overflow of internal memory. When free disk space reaches a critical point, the system has no place to store temporary files for fast operation. Android requires a buffer zone for proper functioning.

You need to audit the storage regularly, remove old screenshots, unnecessary videos and documents that you no longer use, and pay special attention to messengers like WhatsApp and Telegram, which have the ability to accumulate gigabytes of cached images.

⚠️ Warning: Do not delete system files or folders with names that you do not know the meaning of, which can lead to unstable operating system or complete failure of the smartphone.

For deep cleaning, use the built-in Security tool. Go to the menu and select Clean. The system will analyze the device and suggest that you delete temporary files. It is also useful to manually clear the cache of heavy applications through settings.

• 🗑️ Remove unused apps that you haven’t used in more than a month.
• 📸 Move photos and videos to a memory card or cloud storage to free up space.
• 🧹 Use the Cleanup feature regularly in a standard security application.

Once you have at least 15-20% of the memory, you will notice that the smartphone is responding to commands faster, and this is one of the most effective ways to speed up the Redmi 9C without losing data.

Optimization of animation and MIUI interface

Xiaomi’s MIUI shell is famous for its visual appeal, but the abundance of animations can strain the processor of a budget device. To make the interface more responsive, you can reduce the duration of transitions or turn them off altogether, creating the illusion of a significant increase in performance.

To access the hidden animation settings, you'll need to activate the developer menu. Go to Settings → About the phone and quickly press 7 times on the item "Version" MIUI". After you have become a developer, go back to the main settings menu.

💡

Use a theme with minimalist design. Heavy themes with live animations and widgets can significantly reduce FPS on the Redmi 9C.

Now, look for the section Additional → For developers, and in this list, you'll find the parameters that determine the scale of the animation, and changing them will instantly affect the speed of opening windows and menus.

• ⚙️ Find the item "Scale of window animation" and set the value 0.5x or off.
• 🚀 Change the "Scale of Transition Animation" to 0.5x speed up navigation.
• 🎨 Reduce the "Scale of the Animator Duration" to a minimum for performance.

Don't be afraid to experiment with these settings, because they don't affect the stability of the applications, they only change the visual perception of speed. If you don't like the result, you can always return the values back.

Background Process Management and Autoboot

Many applications continue to run in the background even after you shut them down, and they consume RAM and CPU resources, which is especially critical for the Redmi 9C model with its modest specs. Autoboot control is a key point in optimization.

In battery and performance settings, you can limit the background activity of programs. Go to Settings → Apps → Set up apps. Choose unnecessary services such as stores, news feeds or games, and prevent them from auto-starting.

It's also worth checking the list of special rights apps. Often social networks require permission to work in the background, which constantly wakes up the processor.

A good prioritization will allow the system to direct all resources to the programs you actively use, which is especially important when you start a "hard" task.

Disabling advertising in the MIUI system

One of the hidden causes of the workload on the processor is system advertising. MIUI advertising modules periodically load content, consuming Internet traffic and computing power. Disabling advertising will not only speed up work, but also increase the comfort of use.

First, you need to disable the msa service (MIUI System Ads). Go to Settings → Passwords and Security → Data Access. Find the msa list and deny it access to the network. The system will try to cancel the action - click "Cancel" several times until the ban takes effect.

⚠️ Note: Disabling system services may affect the performance of personalized recommendations. If you notice a failure in the standard widgets, return network access for msa service.

Next, remove ads from standard applications. Every system application (Conductor, Music, Themes) has a "Receive recommendations" switch in the settings. Turn it off wherever you find it.

Once you do this, the interface will be cleaner and the load on the processor will decrease, and you will no longer notice the slowdowns when you open folders, which are often caused by loading banner ads.

Using Developer Mode to Accelerate

The developer menu hides tools that can dramatically change the behavior of the system, and in addition to changing the animation, there are settings that limit the number of background processes, which makes the system more aggressively unload unused applications from memory.

In the For Developers section, look for the "Background Process Limit" option, and the default is "Standard Limit," and changing that to "No More than 2 Processes" or "No More than 4 Processes" will free up RAM for the current task.

There's also a Do Not Save Action feature, which, if activated, will completely wipe out the activity of the application as soon as you leave the screen, which guarantees maximum speed of the active window, but can increase the time of application re-launch.

Use these settings with caution. Too aggressively restricting background processes can cause the music to stop when switching to another screen, and the navigator to reset the route.

Resetting network settings and software updates

Often, speed issues are not just hardware related, but software bugs in the current firmware version. Xiaomi regularly releases updates that include bug fixes and performance optimizations. Make sure your Redmi 9C has the latest available MIUI installed.

Check for updates in Settings → About Phone. If an update is available, be sure to connect to stable Wi-Fi before downloading. Sometimes a complete reset of network settings helps if the brakes are associated with connection problems.

If the software methods don't work, the radical but effective step is to completely reset to factory settings, which will remove all the software debris and put the phone back out of the box.

💡

Factory Reset is a last resort, and make sure to back up all your important data before you start, as it will be impossible to recover it after a reset without a backup.

⚠️ Warning: Before reset, make sure that the battery is at least 50%. interruption of the reset process due to discharge can cause damage to the system partition and the need to flash through the computer.

To reset, go to Settings → About Phone → Settings Reset → Erase all data. After this procedure, the phone will work as fast as its hardware allows.
