Xiaomi Redmi 7 came out a few years ago, and over time, its performance may no longer meet the requirements of modern applications. MIUI operating system is overgrown with service processes, cache accumulates, and hardware begins to experience difficulties with rendering heavy pages. Users often notice that the interface begins to slow down, and the launch of programs takes longer than usual.
However, don’t rush to replace the device, as there are proven software methods that can restore the former agility. Disabling animations and background processes in the developer menu can visually speed up the interface by 30-40%. In this article, we will discuss a comprehensive approach to optimization that will make the most of the Snapdragon 632 processor and available RAM.
Before we start taking any radical steps, it's important to understand that software acceleration is a balance between speed and functionality. Some visuals that we'll give up for the sake of performance create a nice sense of smoothness, and you'll have to decide for yourself whether it's a beautiful picture or a system that responds instantly to every touch of the screen.
Cleaning the system and optimizing memory
The first step to improving performance should be to thoroughly clean the system of garbage.In the shell of MIUI built a powerful tool Security, which allows you to delete temporary files, remnants of remote applications and cache of system services. Regular use of this tool prevents overflow of internal memory, which is critical for the stable operation of the eMMC drive installed in Redmi 7.
Special attention should be paid to the autoload of applications. Many programs are prescribed in the start of the system and hang in the background, consuming precious CPU resources. To prevent unnecessary applications from running with the phone, go to Settings → Apps → Autorun. Here you need to leave only messengers and system services on, and everything else to turn off.
☑️ Preparing for optimization
Also worth considering is the option of using the Memory Extension feature if it is available in your firmware version, or (manually) limiting background activity of heavy applications. Under the Apps → Settings → Advanced Settings → Memory can be forced to close processes you are not using right now.
- 🗑️ Regularly clean the folder “Downloads” from the old APK-file.
- 📱 Remove apps that haven’t been used for more than a month.
- 🔄 Reboot your device at least once a week to reset system errors.
⚠️ Warning: Completely clearing internal memory (when less than 500MB is free) may result in a cyclical reboot or inability to install system updates.
Setting up the developer mode
The hidden developer menu is the main tool for fine-tuning the performance. To activate it, you need to go to Settings → About phone and quickly click on MIUI version seven times. Once the notification “You became a developer” appears, a new section will appear in the “Additional” menu.
Inside the developer menu, we're interested in rendering options. Find the Search section or scroll down to Draw. This is the animation scale settings: Windows animation, transition animation, and animation duration. These are set to 1x by default. Changing this option to 0.5x or shutting it down completely (without animation) makes the interface visually instant.
What is the limit of background processes?
Another important parameter is MIUI Background Mode, where you can choose performance over energy saving in some firmware versions, and activating this mode causes the Snapdragon processor to run at higher frequencies, ignoring some battery limitations.
- 🚀 Set the scale of animation to 0.5x Balance between speed and smoothness.
- 🛑 Select “No Animation” for maximum interface response speed.
- ⚙️ Insert “Compulsory” GPU-rendering only if a particular application is not working properly.
Don’t change settings that you don’t know, especially those related to USB debugging or driver selection. Incorrect configuration of system flags can lead to unstable operation of the touchscreen or communication modules.
Energy and Temperature Management
The Snapdragon 632 processor in Redmi 7 is prone to trotting when heated. If the device body gets hot, the system automatically resets the clock speed to avoid overheating, leading to sharp falls in FPS in games and lags on menus. So controlling temperature is an important part of acceleration.
In the battery settings (Settings → Battery), select Performance mode only for the duration of the game. For everyday use, it is better to leave Balanced Mode, but adjust the behavior of each application in detail. Go to Energy Saving Applications and for demanding programs select No Limits so that the system does not “strangle” their background processes.
It is also worth checking the battery status. An old battery with high internal resistance may not give the right current under load, causing artificial slowdown. If the phone is several years old, replacing the battery can positively affect voltage stability and, as a result, the operation of the processor.
| Mode of work | Impact on CPUs | Impact on the battery | Recommendation |
|---|---|---|---|
| Savings | Strong constraint | Maximum life | Read only. |
| Balanced | Dynamic. | Average. | Daily use |
| Productivity | Maximum frequency | Quick discharge. | Games and hard challenges |
| Ultra-economist | Minimum | Extremely extreme. | Survival regime |
⚠️ Attention: Constant operation in maximum performance mode accelerates battery degradation and increases the risk of overheating of the case when used in the case.
Optimization of display and graphics
The Redmi 7 screen has HD+ resolution, which is a plus for performance, as the processor needs to render fewer pixels than in FullHD models. However, if you installed live wallpaper or heavy widgets on the desktop, it can significantly load the Adreno 506 graphics accelerator.
For maximum acceleration, switch to static, dark wallpaper. Dark background not only saves energy (although the screen here and IPS, but black requires less brightness of the backlight in general), but also reduces the load on the rendering of the interface.
💡
Use Dark Theme in your screen settings, which not only keeps your eyes open, but also reduces the load on your GUI at night, making your phone more comfortable.
In the display settings section, you should also disable Read Mode and various image enhancements if they are not critical to you. The fewer software filters the system imposes on the output image, the faster the interface responds when scrolling through pages.
- 🖼️ Use static wallpaper instead of live to reduce the load on the GPU.
- 🌑 Include a dark design theme to reduce contrast and load.
- 🚫 Remove widgets from the desktop that are updated in real time.
Resetting and reflashing as a last resort
If software optimization fails to produce the desired results, the radical, but often the most effective, method is a complete factory reset, which allows you to remove all the accumulated software debris, file conflicts and registry errors that may have arisen over the years of use.
To perform the reset, go to Settings → Advanced Settings → Restore and Reset. Select Settings Reset and confirm the action. The phone will reboot and start the cleaning process, which can take up to 10-15 minutes. Once turned on, you will get the device in the “out of the box” state, which often works wonders with speed.
💡
Full reset returns the original system speed by removing all user data and settings, so backup is mandatory.
More advanced users may be advised to install custom firmware (like LineageOS or Pixel Experience). Pure Android without a MIUI shell runs on the Redmi 7 much faster and smoother, consuming less RAM. However, this step requires unlocking the bootloader, which can be difficult for beginners.
⚠️ Warning: Unlocking the bootloader and installing custom firmware cancels the warranty (if it is still valid) and carries the risk of turning the phone into a “brick” if you violate the instructions.
