Owners of the popular Xiaomi Redmi 5 Plus (codenamed vince) often face a slowdown after several years of active use. The Snapdragon 625 hardware platform is still considered one of the most successful in the middle segment, but modern versions of the MIUI shell and heavy applications require more resources than was laid out in the design.
Constant twitching of the interface, long opening of applications and sudden closing of background tasks is not a sentence for your gadget. In most cases, the problem lies not in the physical wear of the processor, but in the software "junk", fragmentation of memory and incorrect animation settings. Competent optimization of the system can restore the responsiveness of even such an age-old device.
In this article, we will discuss a comprehensive approach to speed up the work of Xiaomi Redmi 5 Plus. We will not offer the installation of dubious “accelerators”, but we will consider safe and effective system settings that really affect performance.
Analysis of the current state of the system and memory
The first step to speeding up any Android device is to understand what resources are being consumed right now. Redmi 5 Plus owners need to know that standard 3 or 4 GB of RAM in today's environment is the minimum. When free memory becomes critically scarce, the system begins to actively use the paging file, which significantly slows down the work.
Go to the settings and check the About Phone section to see the amount of memory available. Then go to the developer settings (if activated) or use the built-in cleaning tool. Pay attention to the apps that run in the background: navigators, social networks and marketplaces often eat gigabytes, even if you are not using them right now.
The key factor in productivity is the occupancy of the internal storage, if less is left free. 10-15% total memory (for example, less than the 5 GB 32-GB version), the speed of writing and reading data drops at times. SSD-The drives used in smartphones, work slower when fullness is strong.
For deep analysis, you can use the command through ADB to see a detailed list of processes, but for most users, built-in monitoring is enough. Remove or disable applications that you do not use, especially those that come in the preinstalled build.
Cleaning the system from digital garbage
App cache accumulation is a normal process, but it can grow to giant sizes over time. In Xiaomi’s case, the MIUI shell has a built-in cleaning mechanism, but it doesn’t always remove deep remnants of remote programs.
⚠️ Warning: Do not use third-party software from Play Market with aggressive advertising. They often become a source of load on the processor and battery, creating the appearance of useful activity.
The most effective way is to manually clear the cache of heavy applications. Go to Settings → Apps → All apps. Go to YouTube, Telegram, Instagram, TikTok and other multimedia services. Inside each application, click "Clear" and select "Cache." This will not delete your personal data, but will free up space and can fix errors in the work.
Special attention should be paid to the MIUI folder in the file manager, which often leaves update logs and temporary files, and also check the Download folder, where you may have accumulated APK installation files and documents that you no longer need.
☑️ Checklist for quick cleaning
Another important aspect is removing unused widgets from the desktop, where every weather, news, or currency widget is constantly accessing the network and the processor, draining Redmi 5 Plus resources.
Optimization of the interface and animations
The visual smoothness of MIUI often gives a false impression of speed. On the Redmi 5 Plus, with its 1080×2160 screen resolution and Snapdragon 625 processor, rendering complex animations can take precious milliseconds, creating a sense of lag.
The most effective method is to scale the animations in the developer menu, and to activate this menu, you need to click on the version 7 times quickly. MIUI In the "About the phone" section, after activation, go to the "About the phone" section. → For developers.
Find three parameters: "Window animation scale," "transition animation scale," and "Animation duration scale." They're 1x by default. Changing the value to 0.5x will visually speed up the interface twice without losing functionality. If you put 0, the animations will disappear completely, which will maximize responsiveness, but the interface will become sharper.
| Animation parameter | Default value | Recommended value | The effect |
|---|---|---|---|
| Window animation | 1x | 0.5x | Apps open faster |
| Animation of transitions | 1x | 0.5x | Instant switching between screens |
| Duration of animation | 1x | 0.5x | Reduces waiting time for action |
Also on the developer menu, find the "Background Processes" item and limit the number of processes if you don't multitask actively. Setting a limit of 2-3 processes will force the system to more aggressively unload the excess from memory, freeing up resources for an active application.
Managing Autoboot and Background Processes
One of the main causes of battery drain and slowdown is the uncontrolled operation of applications in the background, which is responsible for MIUI Optimization and built-in antivirus in the Xiaomi ecosystem.
In the "Security" app (green lightning icon), look for "Permissions" → "Out-run" section, and you only need to leave the apps that are critical to you (such as messengers or alarm clocks) on, and everything else, including stores, browsers and games, should be turned off.
⚠️ Note: Disabling Xiaomi system services (Mi Service, Mi Cloud, GetApps) in boot can lead to unstable notifications and synchronization.
You should also check the battery settings for each application. Go to Settings → Battery and Performance → Battery Consumption. Select the application and set “No Limits” mode only for important messengers. For the rest, choose “Saving Charge” or “Smart Mode” so that the system can monitor their activity.
The secret function of MIUI
Work with the storage and file system
The speed of the Redmi 5 Plus is directly dependent on the speed of reading data from internal memory. As mentioned earlier, crowded memory is enemy number one.
If you use a microSD card to store apps or photos, make sure it has a speed class of at least Class 10 or UHS-I. A slow card can slow down the entire phone if the system tries to read data from it. Ideally, all applications should be installed in internal memory.
Factory Reset is a radical but most effective method, which removes all accumulated system errors, database conflicts and hidden debris, returning the phone to the "out of the box" state.
Before reset, be sure to back up your contacts and photos in Google Photos or on the Mi Cloud disk. After reset, do not rush to restore all applications immediately from the backup, it is better to install only the most necessary things again.
Temperature and trottling
The Snapdragon 625 processor is known for its energy efficiency, but it is also prone to trottling (forced frequency reduction) when overheated. If the Redmi 5 Plus body heats up a lot, the system automatically slows down to avoid damage.
Check if the case covers the vents or the back cover too tightly. Using the phone while charging, especially fast, often causes heating. In these situations, interface lags are a normal protective reaction.
Avoid using your phone in direct sunlight. Overheating the matrix and the processor not only causes brakes, but also accelerates battery degradation and the pixels of the screen burn out.
💡
Use “light” versions of apps (Lite). For example, Facebook Lite or Google Go consume significantly less CPU and RAM, which is critical for the Redmi 5 Plus in 2026 and beyond.
Software and firmware updates
The issue of updating MIUI on older devices is ambiguous: on the one hand, new versions contain security optimizations and bug fixes, on the other hand, each new version of the shell becomes heavier for the old iron.
If your Redmi 5 Plus runs on an older version of Android (like Android 7 or 8) and you get an offer to upgrade to a heavy version of MIUI 11 or 12, it's worth weighing the risks.
However, if you use custom firmware (Custom ROM) like LineageOS or Pixel Experience, you can get a fresher Android and cleaner system without the excess Xiaomi software.This can give a second life to the device, but requires firmware skills.
💡
Stability is more important than novelty. If the current firmware version is stable, don’t rush to upgrade to the latest available version of MIUI, as it can be optimized for more powerful processors.
