Owners of the popular budget smartphone often notice that over time, the device begins to work slower, and free space in the storage disappears without a trace. the Redmi 5 model, released in 2017, was originally equipped with not the most advanced components for its time, so the issue of optimization for it is especially acute. If your phone began to “brake”, open applications for a long time or spontaneously close programs, it needs competent technical cleaning.
There are many reasons for the performance decline, from the banal overflow of cache to the accumulation of system errors after numerous Android updates. In this guide, we will discuss safe and effective methods that will help return the Xiaomi Redmi 5 to its former speed without having to carry it to the service center. MIUI.
Before embarking on radical measures like a full reset, it's worth trying less aggressive cleaning methods. Freeing up internal memory is the first and most important step, which often solves 80% of performance problems. Modern applications are taking up more space, and 16 or 32 GB of internal storage are filled in literally a few months of active use.
Memory Occupancy Analysis and Garbage Removal
The first step is always diagnostics, and you need to understand what's eating up precious gigabytes. The MIUI shell that's on Redmi 5 has a built-in tool that allows you to quickly assess the situation. Go to the Security app and select Cleanup, and the system will automatically scan the device and suggest that you delete temporary files.
But automatic tools don't always find everything that's superfluous. Often, the bulk of the content is media files from messengers. WhatsApp and Telegram have a habit of storing every image and video they receive in their phone's memory. To clean that data, you have to go to the settings of a particular application and find the section "Data Use and Storage" where you can safely delete the media cache.
Also worth paying attention to is the Download folder in the file manager. Users often forget about downloaded installation files. APK, PDF-Deleting them will not affect the system, but will free up a significant amount of space. Remember to check the gallery basket, as deleted photos often stay there for another 30 days, continuing to occupy space.
- 🗑️ Remove the cache of heavy applications through storage settings.
- 📸 Clean the “Recently Deleted” folder in the Photo Gallery.
- 💬 Check the attachments in messengers and remove old videos.
- 📂 Sort the files in the Downloads folder by size and delete the extra.
⚠️ Note: When cleaning memory through the file manager, be extremely careful with system folders. Only delete files that you know the purpose of (photos, videos, documents.
After manual cleaning, it is recommended to restart the device, which will allow the system to redistribute resources and complete the deletion processes, and if after this manipulation the free space still runs out too quickly, it may be the background activity of the applications or the presence of duplicate files.
Application and background processes management
The next important aspect of Xiaomi Redmi 5 optimization is controlling installed programs. Many applications, even if you don’t use them, continue to run in the background, consuming RAM and battery power. MIUI has a rather aggressive memory management policy, but it does not always cope with “voracious” programs like social networks.
Go to Settings → Apps → All apps. Go through the list and find programs you rarely use. They are best removed completely. For system applications that cannot be removed in the standard way, you can turn them off or limit background activity. This is especially true for pre-installed services of Google and Xiaomi that are not used in your region.
The AutoRun feature deserves special attention, because if you allow an application to start automatically, it will hang in the memory immediately after you turn on the phone. Limit this function only to instant messengers, which require instant notifications. Other programs, such as marketplaces or news aggregators, autoruption will only harm performance.
☑️ Optimization of applications
There's also a hidden option for advanced users to turn off the animation interface, which won't free up memory, but will make the system work faster and more responsive visually, and you need to activate the developer mode (click seven times on the build number in About Phone) and find the animation scales of windows, transitions and durations in the Developers menu. Set 0.5x or turn them off altogether.
- 🚀 Turn off auto-run for all apps except instant messengers.
- 📉 Reduce the scale of animation in developer mode.
- 🔒 Limit background work for applications that don’t require online mode.
It's important to understand that completely closing applications through the multitasking menu is not always useful. Android itself is able to effectively manage RAM. Constant "killing" processes can lead to applications running again, consuming more CPU power. Use memory cleaning only when the phone actually starts to hang.
Cleaning the cache and temporary files of the system
Cache is temporary data that apps save to speed up their work. Over time, cache can grow to gigabytes, especially on browsers, YouTube and Instagram. Cache clearing is a secure procedure that doesn't delete your logins, passwords or game progress, but frees up space on the drive.
You can use Recovery mode for deep cleaning. To get into it on Redmi 5, turn off your phone, then press the power and volume buttons at the same time. In the menu that appears (manage volume buttons, select the power button), select Wipe Cache. This action will remove the system cache accumulated during use of the device.
Don't confuse cache cleanup with Wipe Data. If you choose the wrong item in Recovery, all your data will be permanently deleted. The Wipe Cache section only deletes temporary system files without affecting the user's personal photos, contacts and applications. Be careful when navigating the recovery menu.
⚠️ Warning: If after cleaning the cache in Recovery mode, the phone behaves strangely or turns on for a long time, do not panic. 5-10 minutes as the system reassembles temporary files.
It’s also worth cleaning the cache of a particular “heavy” app through settings. For example, you can find hundreds of megabytes of garbage on YouTube or Chrome. Go to Settings → Apps, select the desired app, and click “Clear Cache.” Doing this regularly is a good habit for keeping the Xiaomi Redmi 5 healthy.
Using third-party utilities for optimization
While MIUI is powerful enough, sometimes you need a more powerful tool. There are many cleaning applications on the market, but not all of them are useful. Many of them are themselves "viruses" that load the system with advertising and unnecessary processes. Choose only time-tested solutions.
Files by Google is considered one of the best tools, it is safe, it contains no ads and can find duplicate photos, fuzzy pictures and old screenshots. SD Maid (in the paid version) is also well-established, which knows how to find “dead” files – the remnants of remote applications that ordinary cleaners do not see.
But be careful with so-called "boosters," which promise to increase RAM by 200% -- a marketing ploy -- they just force the shutdowns that the system will start again in a minute, and use such aggressive cleaners on a weak Redmi 5 processor can even make things worse, consuming battery life.
💡
Use Files by Google to find duplicate photos and large files you may have forgotten to delete.
If you choose to use third-party software, give it the minimum permissions it needs. Don't allow unknown cleaners to access your contacts, calls, or location. Often, these apps collect user data under the guise of "system analysis."
Radical measures: Resetting to factory settings
If the software cleaning didn’t work and the phone continues to run slowly, the last effective method is a full reset, which will return the Xiaomi Redmi 5 to the state it was in on the day of purchase, and all data, including contacts, photos, apps and settings, will be permanently deleted.
Before starting the procedure, make sure to back up your data. You can use the Mi Cloud service, Google Drive or just copy important files to your computer. Also make sure that the battery is at least 50% so that the phone does not turn off during the reset process.
You can reset in two ways: One is through the settings menu: Settings → Advanced Settings → Reset and Reset → Recovery. The second is through Recovery mode (phone off, power clamping + volume up), selecting Wipe Data. The second is necessary if the phone is not turned on or locked on the screensaver.
| Parameter | Clearing the cache | Resetting (Hard Reset) |
|---|---|---|
| Data retention | All data is stored. | All data is deleted |
| Impact on the system | Deletion of temporary files | Complete system reinstallation |
| Duration | 1-2 minutes | 10-20 minutes + setting up |
| Recommended frequency | Once a month | Only in serious problems |
After reset, take your time to install all the apps at once. Install only the essentials and watch the phone run for a couple of days. Often, it turns out that one particular app created the problem that you didn't even know existed. Gradual installation of programs will help identify the brake culprit.

Prevention and useful tips for operation
To avoid the question of “how to clean Xiaomi Redmi 5” getting up too often, it is important to follow the rules of digital hygiene (APK-They often contain advertising modules that mine cryptocurrency or show ads in the background, loading the processor.
Update your system regularly if new MIUI versions are coming out for your model. While updates can sometimes slow down for older devices, security and optimization patches often fix critical bugs. However, if the phone is running consistently on the current version, it's best not to upgrade to the latest available firmware, as it can be heavier for the hardware.
Use lighter versions of apps. For older smartphones, there are versions of programs with the prefix “Lite” (for example, Facebook Lite, Google Go) They consume less resources and space, which is critical for Redmi 5. Disabling automatic app updates in the Play Market will also help monitor changes in the system.
- 🛡️ Install a reliable antivirus if you download files from the Internet often.
- 🔄 Don’t store hundreds of screenshots and unnecessary images in the gallery.
- 📵 Reboot your phone periodically (at least once a week).
⚠️ Warning: Avoid using live wallpaper and heavy widgets on the desktop.They constantly use the resources of the processor and graphics card, which leads to rapid battery discharge and reduced overall responsiveness of the interface.
Compliance with these simple rules will prolong the life of your smartphone. Xiaomi Redmi 5 is a reliable device that, if properly maintained, can serve as faith and truth even a few years after the release.
