The smartphone Redmi 7, released by the company Xiaomi, has long remained a popular budget solution due to its reliable body and autonomy. However, over time, many users encounter an unpleasant situation: the device begins to work slowly, applications open with a delay, and the interface responds to touches with a delay. This is especially noticeable against the backdrop of the release of new versions of applications that become more demanding of resources processor and RAM.
The main reason for the decrease in performance lies in the natural wear and tear of the software and the accumulation of system garbage. RAM of 2 or 3 GB, which was quite enough at the start, today is filled with background processes almost instantly. In addition, constantly filling the built-in storage with data leads to a drop in writing and reading speeds, which directly affects the overall responsiveness Android.
You shouldn’t immediately run to a service center or think about buying a new gadget. In most cases, the problem can be solved using software methods without resorting to complex repairs. Below we will analyze in detail the algorithms of actions that will help restore your phone to its former speed and smooth operation.
Analysis of system load and background processes
The first step to solving the problem is diagnosing the current state of the system. Often, users do not even suspect which apps are consuming the lion's share of resources in the background. The processor Snapdragon 632installed in this model is quite capable of coping with everyday tasks if it is not overloaded with unnecessary processes.
First, you need to go to the settings and check the battery and memory usage statistics. Heavy applications, such as social networks or instant messengers, can run in the background all the time, even if you do not use them. This creates a constant load on RAM, crowding out other important system services.
⚠️ Warning: Some system processes may appear as consuming a lot of power, but this is normal for operation. MIUI. Do not try to force stop services with names containing "System", "Google" or "Xiaomi" if you are not sure of their purpose.
Pay attention to the Memory Expansion feature if it is available in your firmware version. It uses part of the persistent storage as virtual RAM. On older drives, this may, on the contrary, slow down due to low file system reading speed.
Cleaning the built-in storage from garbage
A full internal storage is one of the most common reasons that Redmi 7 starts to slow down. When free space is less than 10-15% of the total, the system cannot effectively create the temporary files and cache needed for performance. This leads to noticeable freezes when switching between applications.
Standard Security application from Xiaomi has a built-in cleaning tool. However, for deep cleaning it is better to use the file manager manually. Delete old downloads, unused APK installer files and duplicate photos that are often copied when synchronizing with instant messengers.
Particular attention should be paid to the cache of messengers such as Telegram and WhatsApp. These applications can take up gigabytes of space, storing all the photos and videos you watch. Clearing the cache inside the settings of these applications is safe and will not delete your correspondence, but will free up valuable space.
☑️ Deep memory clearing
Optimizing animations and MIUI interface
Shell MIUI known for its beautiful, but heavy animations. On budget devices like Redmi 7 rendering complex transitions can take too long, creating a feeling of lag. Disabling or speeding up animations is an easy way to visually speed up your smartphone without losing functionality.
To access these settings, you need to activate developer mode. Go to Settings → About phone and quickly click on the "MIUI Version" item seven times in a row. After the message about activating developer mode appears, go to menu Settings → Additional settings → For developers.
Find three items related to animation in the list: “Window Animation”, “Transition Animation” and “Animation Duration”. Change the value in each of them from 1x to 0.5x or completely disable (Off). This will make transitions between screens instant and reduce the load on the graphics accelerator.
If the UI seems too harsh after disabling animations, try setting the value to 0.5x instead of disabling it completely. This will maintain smoothness, but speed up the response.
Managing startup and application permissions
Many installed apps tend to start immediately after turning on the phone, taking up space in RAM even before you start using the device. Startup control is a critical stage of optimization for devices with small capacity. RAM.
In the settings MIUI there is a special section for controlling autostart. Disable this feature for all applications that do not require immediate operation (for example, games, calculators, photo editors). Leave autorun enabled only for messengers if instant notifications are important to you.
It’s also worth reviewing application permissions. If a simple flashlight or calculator asks for access to geolocation, contacts, or microphone, it's suspicious. Such applications can collect data in the background, loading the processor. Revoke unnecessary permissions in the menu Applications → Permissions.
| Application type | Recommended action | Impact on speed |
|---|---|---|
| Social networks | Limit background activity | High |
| Games | Prohibit autorun | Medium |
| Launchers | Use only one | Critical |
| Antiviruses | Delete (the built-in one is enough) | High |
Reset settings to factory settings
If software cleaning and disabling animations did not give the desired result, the system may have accumulated critical registry errors or file conflicts. In this case, the most effective solution would be to completely reset the device to factory settings. This will return the phone to its out-of-the-box state.
Before starting the procedure, be sure to create a backup copy of all important data: contacts, photos and documents. A reset will delete absolutely all user information without the possibility of recovery. Go to Settings → About phone → Reset settings and select "Erase all data".
⚠️ Attention: Make sure the battery charge is at least 50% before starting the reset. Interrupting the process by turning off the phone can damage the system partition and turn the device into a “brick.”
After rebooting, do not rush to install all applications at once. Test the phone in a “clean” state. If it works quickly, then the problem was software junk. Install applications gradually, monitoring after installing which app the brakes appear again.
What to do if the reset did not help?
If even after a complete reset the phone continues to work slowly, the problem may be hardware. Often the eMMC memory chip degrades or the processor overheats due to dried out thermal paste. In this case, diagnostics in the service are required.
Hardware limitations and replacement of components
You cannot ignore the fact that Redmi 7 the device is several years old. Physical wear and tear of a memory drive component causes data reading speed to drop significantly. This cannot be corrected using software methods, since the memory cells lose their physical properties.
Overheating should also be taken into account. Dust that has accumulated inside the case over years of operation impairs heat dissipation. When the processor gets hot, it automatically reduces the clock speed (throttling) to avoid burning out, which manifests itself in severe lag. Careful cleaning of dust and replacing thermal pads can restore previous performance.
Using a slow memory card microSD can also affect the performance of the system if parts of applications are transferred to it or a lot of media files are stored that the system constantly indexes. Try removing the memory card and checking the phone's operation without it.
An integrated approach: a combination of clearing memory, disabling animations and autorun control gives better results than using only one method.
Frequently asked questions (FAQ)
Why does Redmi 7 slow down after updating MIUI?
New versions of the shell often require more resources than the old ones. After the update, the system indexes files in the background, which can take up to 2-3 days. If the brakes do not go away after a week, perhaps the new version of the firmware is too heavy for the given hardware, and it is worth considering rolling back to the previous version.
Will installing a third-party launcher help?
Yes, replacing the standard launcher MIUI with a lighter one (for example, Nova Launcher or Lawnchair) can significantly reduce the load on RAM and speed up desktop recall. However, this will not solve the problem of slowdowns inside heavy applications.
Is it possible to overclock the processor on Redmi 7?
Theoretically, this is possible if you have root access and install a special kernel, but for budget devices this is extremely risky. Overclocking will lead to rapid overheating and accelerated battery wear, and the performance gain will be minimal and unstable.
How often should you clear the cache on Android?
Modern versions Android manage the cache independently. Forced cleaning "just in case" is not required. It makes sense to clear the cache only for specific applications that have taken up an abnormally large amount of space (more than 500 MB), or before installing major system updates.
