Xiaomi Redmi 7, launched in early 2019, has long been considered the king of the budget segment thanks to its Snapdragon 632 processor and huge battery. However, with the release of new versions of the MIUI shell and the update of heavy applications, device owners are increasingly noticing a slowdown in the interface, hanging when switching between programs and long loading pages.
You don’t have to think about buying a new gadget right away, as there are many software methods that can breathe life into the device. Competent system configuration allows you to free up RAM, reduce the load on the CPU and remove visual delays. In this article, we will discuss proven ways to help the Redmi 7 work faster and more responsive in everyday tasks.
Before we go to radical measures like a full reset, it’s worth trying comprehensive customization. Often the problem isn’t the hardware, but the accumulated software debris and background processes that devour resources. System optimization is the first step that every user should take.
Analysis and release of RAM
The main “narrow neck” in Xiaomi Redmi 7 is the amount of RAM, which in the basic versions is only 2 or 3 GB. Modern applications, especially social networks and instant messengers, consume much more resources than a couple of years ago. When free memory ends, the system begins to actively use the paging file on the internal drive, which leads to noticeable brakes and jerks of the interface.
The first thing you need to do is check which apps are running in the background. MIUI has a built-in tool to see the current load, go to the settings and find the advanced settings section to access the memory usage statistics.
⚠️ Warning: Don’t use third-party Task Killers apps from the Play Market. They often run worse than Android’s built-in mechanisms, causing a constant reboot of services that only drains the battery and loads the processor.
You can use the engineering menu or standard developer tools to manually control processes. Disabling unnecessary system services, such as unused widgets or live wallpaper, will immediately give you an increase in productivity. The live screensaver is a beautiful but very resource-intensive element that on a budget Snapdragon 632 processor is better replaced with a static image.
Regular cache cleaning also plays a role: Apps accumulate temporary files that can take up gigabytes of space over time and slow down access to data. Use the built-in Security app to conduct deep cleaning of the system.
Optimization of MIUI interface and animations
MIUI is famous for its beauty and functionality, but the abundance of animations can create the illusion of slow operation on devices with 60 Hz screens. In Redmi 7, turning off or speeding up transitions between screens visually makes the system more “live” and responsive. This does not increase real computing power, but reduces the waiting time for the interface response.
To access hidden speed settings, you need to activate developer mode, which is a standard procedure for Android smartphones, which allows you to fine-tune the graphics rendering parameters, and once activated, the menu will appear in the main settings of the system.
☑️ Activation of the developer mode
In the developer menu, find the animation section, and there are three main parameters: window animation scale, transition scale, and animation duration, which are set to "1x" or "Animation enabled," and changing those values to "0.5x" or turning them off completely will speed navigation.
Also worth noting is the Advanced Memory feature, which some firmware versions for Redmi 7 offer the option of using part of the RAM as RAM. While this may help in multitasking, the speed of such virtual memory is lower, and in some cases, turning it off can even stabilize the performance of heavy applications.
| Setup parameter | Default value | Recommended value | The effect |
|---|---|---|---|
| The scale of window animation | 1x | 0.5x or Off | Instant application opening |
| Scale of transition animation | 1x | 0.5x | Screen flipping fast |
| Background of processes | No restrictions. | No more than 2-3. | RAM release |
| USB debugging | Off | Off (if not used) | Security and resource savings |
Remember, completely disabling animations can make the interface less friendly, so the middle ground is 0.5x. This keeps visual effects smooth, but cuts the time to play them in half.
Managing Autoboot and Background Processes
One of the main reasons why Xiaomi Redmi 7 starts to work slowly after purchase is uncontrolled autoload of applications. Many programs prescribe themselves in start-up to constantly receive notifications or update data, even if you are not using them right now, which puts a constant strain on the processor and battery.
MIUI has a powerful built-in tool to control startups, which allows you to prevent selected applications from running with the system, especially for heavy applications that you rarely use, such as online banking or specific delivery services.
What apps can't be turned off?
To manage this, go to the Security app, then select the Permissions section and find AutoStart. Here you will see a list of all programs that start automatically. Leave only those that you really need in the background on.
In addition to autoboot, it is worth checking application permissions. Often unnecessary programs have access to geolocation, microphone or other resources that they poll in the background. Background activity restriction for specific applications can be configured in the Battery and Performance section -> Charge Savings -> Background constraints.
⚠️ Be careful when disabling system processes with names that contain System», «MIUI» Or Google. Shutting down critical services can cause the phone to stop working properly or go into a cyclical reboot.
Regularly auditing installed applications will help you identify resource eaters. Go to your battery settings and look at your consumption statistics. If you see an application that you rarely use but consumes a lot of CPU power and resources, you better remove it or limit it.
Cleaning internal memory and cache
Internal storage is critical to the speed of any Android smartphone, and Redmi 7 is no exception: When disk space runs out, data write and read speeds drop, causing severe lags when installing updates, launching cameras or saving files.
It is recommended to always keep at least 15-20% of the total internal memory free. If you have a version with 16 or 32 GB of memory, this issue is especially acute. The first step should be to clean the download folder and the cache of instant messengers, which often take up gigabytes of space.
The Explorer and Cleanup app in MIUI can quickly find large files, but for more in-depth analysis, you can use specialized tools to show which folders have grown the most, often cache cards, saved YouTube videos or forgotten videos from WhatsApp.
💡
Use the Cloud function or transfer photos and videos to a microSD card, which will free up valuable internal space for the system and applications to run.
App cache is a special focus, and over time, browsers and social networks accumulate huge amounts of temporary data, and cleaning the cache will not delete your personal data (login, passwords), but will free up space and can eliminate errors in the operation of programs.
If deleting the extra files doesn't help, porting the apps to the memory card, if this feature is supported by firmware and the Android version, and although the memory card is slower than the internal one, it will unload the main partition of the system.
Resetting to factory settings as a radical method
If software optimization and cleaning didn’t work, the most effective way is to reset the phone to a factory setting (Hard Reset), which returns the phone to the state it was in at the time of purchase, removing all accumulated software debris, registry errors and configuration conflicts.
Before you do this, it's critical to back up all your data, reset it will delete everything: contacts, photos, apps and settings, use Mi Cloud, Google Account or computer to save important information.
The reset procedure is done through the settings menu, you go to About Phone, select Settings Reset and confirm the action, and the phone will restart and begin the cleaning process, which can take 5 to 15 minutes.
⚠️ Warning: Make sure the battery is at least 50-60% Interrupting the process by turning off the phone can cause damage to system files and the need to flash through the computer.
After reset, don't put all the apps back in, try using a clean phone for a couple of days, and it helps you see if the slowdown was caused by software, and install the apps gradually, tracking the performance impact of each.
Update and work with MIUI
Xiaomi periodically releases security and optimization updates even for older models. Check for updates in the About menu. Sometimes newer versions of firmware contain patches that improve the stability of memory and processor.
However, there is a downside: newer versions of MIUI may be too heavy for the old hardware. If the phone gets worse after the upgrade, consider rolling back on the previous version or installing custom firmware (for advanced users). Lighter versions of Android (like LineageOS) can work wonders on the Redmi 7.
It’s also worth checking the app version. Outdated versions of software may not work properly with new server protocols, causing freezes. Update apps through Google Play, but make sure that new versions don’t get too heavy for your device.
💡
Regularly updating system components and applications is key to security, but on older models it is sometimes better to stay on a proven firmware version.
In conclusion, the comprehensive maintenance approach of the Xiaomi Redmi 7 will significantly extend its life of comfort, and the combination of memory cleaning, fine tuning of animations and autoboot control works wonders.
