Xiaomi Redmi Note 7 has been a hit of its time, offering users a high-quality camera and a productive Snapdragon 660 processor at an affordable price. However, with the release of new versions of the MIUI shell and modern demanding applications, the device may start to work slower than in the first months after purchase, it is a natural process of aging software and accumulation of digital debris in the system.
There are many proven ways to get your gadget back up without having to replace it. Competent system setup, disabling unnecessary services, and properly caring for the file structure can work wonders. In this article, we will detail how to improve the performance of the Xiaomi Redmi Note 7, making it fast and responsive again.
Before we go to radical measures, we should try software optimization methods, which require no special skills and allow you to safely improve performance, and it is important to understand that RAM and storage devices tend to fill up, which directly affects the response rate of the interface.
Cleaning up the system and freeing up resources
The first step to speed up your smartphone should be to thoroughly clean up your internal storage. When the free space on the disk runs out, the system has no place to place temporary files and cache, which causes noticeable slowdowns. Delete unnecessary applications, old photos and video files, transferring them to your computer or to the cloud storage.
The second important step is cleaning up the cache of running apps. Social media and instant messengers tend to accumulate huge amounts of temporary data that not only takes up space, but can conflict when updated. Use the built-in Security app or third-party utilities to deep-clean up garbage.
☑️ Checklist for quick cleaning
Remember to check the Downloads folder regularly, where installation files and documents often accumulate, and it is also worth analyzing the memory usage through the system settings to find the "eaters" of space. 15-20% The total amount of the drive will significantly improve the work of the file system.
- 🧹 Remove unused apps through the Settings menu.
- 🗑️ Clean the Recycle Bin in Gallery and File Manager.
- 📦 Move heavy media files to the SD-map.
- 🔄 Reset the cache of Google system services.
Accelerating MIUI interface and animations
MIUI is famous for its visual richness, but the abundance of animations can visually slow down the device. Hidden developer settings allow you to change the scale of the animation of windows, transitions and duration of the animator. This is one of the most effective ways to make the interface more responsive without losing functionality.
To access these options, you need to go to About Phone and click on the MIUI build number seven times. Then the Developer Menu will appear in the advanced settings, find the items that are responsible for the animation scale, and change their value from 1x to 0.5x or completely disable them.
Risks of changing animations
You should also look at the memory extension feature, if it's available in your firmware version, which allows you to use part of the internal drive as virtual RAM, and while it doesn't give you the speed boost that you would expect from real RAM, it helps the system keep more applications in the background.
- ⚙️ Activate the developer mode taps by build number.
- 🎞️ Reduce the scale of animation to 0.5x speed up response.
- 🚀 Enable high performance mode in battery settings.
- 📱 Turn off live wallpaper to save resources GPU.
Combating Advertising and Systemic Restrictions
One reason why the Xiaomi Redmi Note 7 may be slower is the background activity of MIUI advertising services. The system constantly loads content for news feeds and recommendations, consuming Internet traffic and CPU time.
First, turn off the msa service (MIUI System Ads) in password and security settings, which will remove most of the intrusive advertising in system applications, and it is also recommended to disable receiving recommendations in the settings of each system application, such as Explorer, Music and Themes».
⚠️ Note: Complete shutdown of system services through ADB This can cause notifications to be unstable, and use caution to disable only known advertising components.
Another important thing is to limit background activity for applications you rarely use, so go to the battery settings for each application and select No Limits mode for messengers only, and set a hard limit for others, which will prevent them from running hidden in the background.
Optimization of battery and processor
The state of the battery directly affects the performance of the processor. When the charge falls below a certain level or the battery degrades, the system automatically reduces the clock speed of the Snapdragon 660 to prevent a sudden shutdown, a phenomenon called trottling.
Check the battery status on the engineering menu or with special diagnostic applications. If the battery wears more than 20-25%, you should think about replacing it. The new battery will not only increase battery life, but also allow the processor to work at maximum frequencies longer.
In the energy saving settings, select Balanced or Performance mode depending on your tasks. Energy Saving mode severely limits background processes and processor frequency, making the sluggish smartphone work.
| Mode of work | Impact on CPUs | Screen impact | Recommendation |
|---|---|---|---|
| Economical | Strong constraint | Decrease in brightness | Only at low charge. |
| Balanced | Normal work. | Auto-brightness | Daily use |
| Productive | Maximum frequency | No restrictions. | Games and hard challenges |
| Ultra Battery | Minimum frequency | C-B regime | Emergency. |
Update or roll back version
On the one hand, new versions of MIUI contain security fixes and optimizations; on the other hand, for devices of previous years, new shells often become too heavy. If the phone starts to perform worse after an update, it may be worth considering a rollback to a lighter version.
Before any update or rollback, make sure to make a full backup. The flashing process carries risks, and having a backup will allow you to quickly restore contacts, photos and settings. Use built-in backup or cloud services.
💡
Use only official sites to download firmware. Third-party builds may contain malicious code or have critical driver errors.
If you decide to stay on the current version of the software, perform a full reset (Wipe Data) after installing the update.This will delete old system files that may have conflicted with the new version of Android. Clean installation often solves problems with heating and lag after the update.
- 📥 Download the firmware only from the official resource MIUI bootloader.
- 💾 Backup before any manipulation of the software.
- 🔄 Run Wipe Data when you switch between major versions of Android.
- 🌏 Choose a global firmware version for better stability in our region.
Radical measures: Root and custom firmware
For advanced users looking to get the most out of the Xiaomi Redmi Note 7, there is a way to install custom firmware: unlocking the bootloader and installing pure Android (AOSP) or optimized builds like LineageOS creatively transform the device, such systems are devoid of advertising and heavy Xiaomi software.
Root allows you to remove system applications that cannot be removed by standard methods. You can completely rewrite the control of the power and frequencies of the processor. However, this requires technical knowledge and removes the warranty (if it is still relevant).
⚠️ Warning: Unlocking the bootloader resets all data on the device.Make sure you have a Mi Account and a tied phone number, as the unlocking process can take 3 to 7 days of waiting.
Installing custom TWRP recaptures gives you full control of the file system, you can take full system images, install kernel modifications and patches to improve sound or photo quality, making an old smartphone a powerful tool for experimentation.
💡
Custom firmware can extend the life of the Redmi Note 7 by 2-3 years, providing current versions of Android that are no longer officially supported.
It’s worth noting that some banking apps may not work on devices with unlocked bootloader or Root rights. There are special modules that hide access rights to bypass this restriction, but this is a game of cat-and-mouse with security systems.
