How to Speed Up Xiaomi Redmi: A Complete Optimization Guide

Many Xiaomi smartphone owners notice that the device starts to run slower, apps open longer, and the interface reacts with a delay. It is a natural process associated with the accumulation of system debris, memory fragmentation and constant updating of applications that require more and more resources.

Unlike other manufacturers, the MIUI shell or its modern version of HyperOS has a variety of background processes that consume RAM. Understanding how to manage these processes is key to improving performance. Reducing the screen refresh rate from 120Hz to 60Hz can extend battery life by up to 20%, which indirectly affects the stability of the processor at low charge. In this article, we will break down proven methods to help you speed up your Xiaomi Redmi.

Analysis and cleaning of internal storage

The first step to speed up the device should be a thorough revision of occupied space. When the free space on the internal drive falls below 10-15%, the speed of writing and reading data is sharply reduced, causing noticeable slowdowns in the interface. Standard cleaning tools often leave deep caches of social networks and messengers, which can take up gigabytes.

You need to manually check folders with heavy content, especially video files and downloaded documents in messengers. Deleting unnecessary files frees up resources for system write operations, which directly affects response speed. Use the built-in Security → Cleanup application, but do not limit yourself to it.

For a deeper analysis, it is recommended to use third-party utilities or file managers that will show the real structure of the folders. Android/data, It's where the game and application caches are stored, and cleaning this partition regularly helps keep the system in good shape.

• 🗑️ Remove duplicate photos and screenshots that are often forgotten in the gallery.
• 📱 Clear the cache of Telegram and WhatsApp apps through their internal settings.
• 📂 Move heavy media files to a memory card or cloud storage.
• 🚫 Remove unused pre-installed applications if they are not system-based.

If the place ends up too quickly after cleaning, it is worth checking whether the function of automatic saving of media files is enabled in the cloud with a local copy.

Management of RAM and background processes

The RAM (RAM) in Xiaomi devices is often overloaded with background services that the user did not run on their own. Many applications have the property of automatically starting when the phone is turned on and constantly updating content, consuming valuable CPU resources. Autoboot control is a powerful tool to speed up the system.

You can find a setting in the developer's settings that limits the number of background processes. But be careful: too tight a restriction can disrupt notifications. The best solution is to manually close the "heavy" applications that you don't need right now, swiping from the bottom up in the menu of recent tasks.

⚠️ Warning: Don’t use third-party accelerators and Cleeners from Play Market that promise magical speed increases, they consume resources themselves and often contain aggressive advertising, which only slows down Redmi.

You also need to turn off unnecessary visualization. Transition animations, while they make the interface smooth, require processing power. If your smartphone is not the first freshness, reducing the scale of animation will give a tangible increase in the speed of perception of the interface.

• 🚀 Turn off auto-update apps in Google Play and GetApps for background traffic and CPU savings.
• 🔒 Close background processes through the recent menu before launching heavy games.
• 📉 Limit background activity for rarely used apps in battery settings.
• 🛑 Remove live wallpaper and widgets that constantly update data from the network.

A system memory expansion mechanism known as Memory Extension uses a portion of internal memory as virtual RAM. Enabling this feature in the Additional → Expansion Menu can help if you have little RAM (like 4GB) physically, but the virtual memory speed is lower than the real one.

Customization of animations and MIUI interface

The visual component of the MIUI shell often hides the possibilities for fine-tuning performance. Standard animation settings can be redundant for users who value speed over beauty. Access to hidden settings is opened through the developer menu.

To get to the desired menu, you need to click on the build number several times in the About Phone section. Once the developer mode is activated, a new item will appear in the menu, and here we are interested in three parameters: the scale of window animation, the scale of transition animations and the scale of the animator duration.

💡

Set the animation scale to 0.5x instead of the standard 1x. This won’t eliminate the animations completely, but it will make them twice as fast, creating the illusion of instantaneous system response.

Changing these values doesn't affect the stability of the system, but it changes the subjective sense of speed. The smartphone starts flying as the waiting time for visual effects to finish is reduced, which is especially true for the Redmi Note series of previous years.

Beyond animation, it's worth rethinking the use of the theme: Complex themes with lots of live elements and widgets load the GPU, and going back to a standard theme or using minimalist designs reduces the load on the rendering system.

System update and resetting

Software bugs accumulated over the years can cause unstable work. Xiaomi regularly releases updates that contain not only new features, but also code optimization for specific models.

Go to Settings → About Phone and click on the system version. If an update is available, it is recommended to install it by backing up the data. Sometimes the system reports that there are no updates, but important security patches or improvements may be available in the Services application.

If the updates don't work, a radical but effective method is a factory-wide Hard Reset, which removes all user data, apps, and settings, returning the phone to a store-like state, often eliminating deep system conflicts.

⚠️ Note: Before performing a full reset, make sure you remember the password from your Mi Account and Google Account. Once reset, the phone will require you to enter them to confirm ownership, and without this data, the device can lock.

The reset procedure is performed through the menu Advanced Settings → Resetting → Erase all data. The process will take from 5 to 15 minutes. Once turned on, the phone will work much faster, since all accumulated software “garbage” will disappear.

Optimizing network and connections

Slow performance of a smartphone is often disguised as lags of the system, when in fact the problem lies in waiting for a response from the network: constant search for a signal, switching between 3G/4G/5G and Wi-Fi puts a strain on the modem and the processor. Disabling unused communication modules frees up resources.

If you're not using a Bluetooth headset or a watch, turn off this module. The same goes for NFC if you're not paying with your phone. In mobile network settings, you can try switching the network type, for example, selecting only 4G if 5G coverage is unstable in your region, which causes constant reconnection.

It's also worth checking which apps have access to geolocation. Constantly polling GPS satellites with background apps (like delivering food or taxis you don't use right now) significantly drains the battery and loads the system. Set up geolocation access only for running applications.

• 📡 Turn off Device Search in Bluetooth settings if you don’t connect new gadgets.
• 🌐 Reset network settings if there are persistent connection breaks.
• 📶 Use Flight mode in uncovered areas so your phone doesn’t search for the network for nothing.
• 🔌 Turn off moderator or Wi-Fi distribution when not in use.

In some cases, a problem is caused by a crowded DNS cache or errors in network configuration. Network resets (without deleting personal data) often solve problems with the “sluggish” Internet, which slows down the loading of content in applications.

Use of game mode and special opportunities

For gamers and users who want to maximize performance in specific tasks, MIUI provides a special tool - Game Turbo (or game mode) - it not only collects games into a single folder, but also redistributes the CPU resources in favor of an active application.

When activated, the system limits background activity, clears memory and prioritizes gameplay, which allows you to squeeze extra frames per second and reduce the number of friezes, which is available through a swipe in the corner of the screen during the game or through the Security app.

💡

Game mode is not just a cosmetic feature, but a real CPU and GPU resource management tool that is worth activating even for heavy non-gaming applications such as video editors.

In addition, the special features section has features that can help people with disabilities, but are also useful for control, such as one-handed or voice control can make navigation easier if the touch screen doesn't respond perfectly.

And let's not forget the temperature. If the phone overheats, the system automatically lowers the CPU clock rate (trottling) to cool down, which leads to severe lags. Removing the case during charging or heavy use helps avoid this.
