Owning a smartphone from Xiaomi or Redmi often begins with a delight in the speed of the interface, but over time the operating system becomes overgrown with digital garbage. Accumulated app caches, background processes and memory fragmentation can turn a once-quick device into a slow gadget. Users often face a situation when the menu opens with a delay, and games begin to “slow down” even on medium graphics settings.
But it's too early to rush into buying a new device or completely resetting to factory settings. The MIUI shell and the new HyperOS have powerful fine-tuning tools that many don't know about. Competent optimization can bring back the sharpness of the screen and significantly extend the comfortable life of your smartphone.
In this article, we’ll look at proven methods to help speed up Xiaomi Redmi’s performance without using third-party accelerators, often just loading the system. We’ll touch on the hidden animation settings, auto-start management, and proper memory management to keep your device flying again.
Analysis and cleaning of built-in storage
The first and most obvious reason for the slowdown is the overflow of internal memory. When the space is running out, the system lacks the resources to create temporary files and efficiently run virtual memory, and the critical threshold is when less than 10-15% of the total storage capacity is free.
Unlike older versions of Android, Xiaomi’s modern shells have a powerful tool built in to clean up.It analyzes not only the size of files, but also their type, suggesting that duplicates, old.apk installation packages and unnecessary screenshots be removed. Using third-party cleaners is redundant and can even hurt, as they often contain ads and consume resources themselves.
⚠️ Attention: Before mass cleaning of folder DCIM/Camera or MIUI/gallery/cloud/cache Automatic cleaners can remove important original photos or saved statuses from the messaging service For deep cleaning, use the built-in Security app. Go to Cleanup and wait for the analysis to be completed. The system will offer to delete the cache, remnants of deleted applications and large files, and it is worth looking at the section “Deep Clean”, where you can find forgotten download files and empty folders. ☑️ Checklist of quick cleaningDelete photo from gallery basketClean cache Telegram and WhatsAppDelete downloaded files from Download folderCheck folder with duplicate photosCompleted: 0 / 4 Optimization of animations and visual effects Visual smoothness of the interface is what the user notices in the first place. Animations of opening windows, switching menus, and folding apps are all fun, but they can also steal a fraction of a second of the actual CPU response. If your Redmi starts to slow down, reducing animations is the fastest way to subjectively speed up the system. To access these settings, you need to activate the developer mode. Go to Settings → On the phone and press quickly 7-10 once on the line “Version” MIUI» or "Version" OS», Until the activation notification appears, the "Developers" option will appear in the "Additional" menu, and within the developer menu, find the section related to drawing or animation, and you're interested in three options: "Window animation," "Change animation," and "Duration of animation." They are set by default to the value 1x. Change them to 0.5x or completely disable (without animation). This will make the interface more sharp and responsive. 💡Do not turn off animations completely (value 0) if you have AMOLED-The jumps in frames can look like twitches, and the value can be very high. 0.5x It's smooth, but it's twice as fast, and it's also worth noting that it allows you to use part of your internal storage as RAM, and while that sounds useful, in reality, virtual memory is much slower than the physical memory. If your smartphone has less than 6 GB of RAM, it is better to turn off this feature so that the system does not try to dump active processes there, causing micro-latency. Animation parameter Default Recommended value Window Animation Effect 1x 0.5x Acceleration of Application Opening Animation Transitions 1x 0.5x Quick switching between screens Animation Duration 1x 0.5x General acceleration of the interface Font Scale Standard Small/Standard Visual zoom Control of Autostart and Background Processes One of the main reasons for battery discharge and lags is the excessive number of applications running in the background. Social networks, marketplaces and news aggregators tend to start immediately after the phone is switched on and the system needs to be actively searched together with the system. Leave only messengers (for notifications) and system services on. Everything else, including stores, games and browsers, should be turned off. Next, you need to set the restrictions for each heavy application individually. Go to Settings → Annexes → All applications, select a demanding program (like Facebook or AliExpress) and find Activity Control. Set background activity limits. This will prevent the application from eating up CPU resources when you are not using it. 📊 What is the most important thing to do with your phone?Social networks ⚠️ Note: Do not limit background activity for messengers (WhatsApp, Telegram, Viber) if you want to receive notifications instantly. Cache and application data are temporary files that apps create to quickly download frequently used data. Over time, the cache can reach several gigabytes, taking up space and sometimes causing conflicts in the work of programs. This is especially true for browsers, YouTube and TikTok. Clearing the cache can be done selectively through the settings of each application or en masse through the Security menu. However, it is important to distinguish between Clear the cache and Clear everything. The first operation is safe and deletes only temporary files. The second operation (" Clear everything" or "Reset"), you can only use the logbooks on the last ones, so you can use it for the storage of the data. This won’t delete your photos stored in memory, but it will reset the thumbnail database, which often solves problems with hanging media viewing. How to clear the DNS cache to speed up the Internet?Sometimes the brakes are not connected to the processor, but to the network. Go to Settings → Connection and Sharing → Private DNS. Select “Disable” or write the address of a reliable server, for example, dns.google. This can speed up the loading of pages. There is a special mode for games in Redmi smartphones that can conflict with normal operation of the system, if it really does not use the Turbo, or if it is used to check the backupload the game mode, it is used to help the game. Some features, such as Screen Enlargement or Voiceover, can consume resources even when they are off if they have a software failure. Disabling unused accessibility features is a good tone for optimizing an old device. And we've got a special focus on memory extension, which we mentioned earlier, but we'll get into more detail here. UFS On low-end models with slow flash memory, turning on this feature can backfire, causing the phone to start running slower due to the low read/write speed of the virtual memory. RAM. 💡On devices with 4GB and 6GB of RAM, it is often more profitable to disable virtual memory expansion so that the system only works with fast physical memory. RAM, Avoiding swaps to a slow disk. If the software methods have not produced the desired result, the radical, but most effective way is a complete reset to factory settings, which removes all user data, applications and accumulated system debris over the years. Before this procedure, be sure to back up important data in the cloud or on your computer. → The phone. → Resetting settings → Delete all data. It takes 5 to 15 minutes. Once turned on, you get a clean system that works as fast as the first day you bought it. It often solves problems caused by failed updates or system file conflicts. Don't forget about updates. Xiaomi regularly releases security and optimization patches. → About the phone and check for updates. Sometimes the new firmware version contains fixes critical to the stable operation of a particular module or driver. What if after the update the phone began to work worse? MIUI The system re-indexes files, which can take up to 2-3 During this time, the phone can warm and run slowly. Give it time by plugging it into overnight charging. Why does the Xiaomi phone brake even after cleaning? Often the reason lies in the hardware wear of the battery. When the battery degrades, the system can artificially lower the CPU frequency to prevent a sudden shutdown, it can also cause physical damage to the plume or overheat. Do I need to install antiviruses on Redmi? No, the system already has a powerful scanner built in from the computer. Avast/Tencent (depending on the region that checks applications when installed. Third-party antiviruses only consume battery and RAM by constantly scanning the system. How often should you reboot your smartphone? Modern operating systems do not require daily restarts. Just reboot the device once a week or after installing major application updates to clear RAM from errors. Does a crowded Downloads folder affect speed? Yes, if there are thousands of files in the pack, the system takes longer to build an index and display content when searching.
