How to Speed Up Xiaomi Redmi 5: A Complete Optimization Guide

Owners of the popular Xiaomi Redmi 5 smartphone often face a slowdown after several years of active use. This is a natural process, as modern applications require more resources, and the hardware base of the 2017 model release ceases to cope with the increased load. However, do not immediately think about buying a new gadget, because competent software setting can return the former sharpness of the interface.

There are many ways to extend the life of your smartphone, from simple cache cleaning to deeper system changes, and in this article we will discuss the most effective methods that will help you increase the response rate of Redmi 5 by 30-40% without the need to flash or contact a service center.

Before we take any drastic action, we need to understand the cause of the brakes, and most often, the problem is the overflow of internal memory or the excess of background processes that eat up RAM, and let's look at how to properly diagnose the system and eliminate bottlenecks.

Analysis of the current state of the system and memory

The first step to speed up Redmi 5 is to look carefully at what's taking up resources right now. The built-in MIUI shell provides enough tools to monitor, but sometimes it's not enough to make a deep diagnosis, and you'll need to look at the settings and assess the occupancy of the storage.

Note the partition that displays memory usage. If less than 10% of the total is free, the system will not work properly. The eMMC flash memory installed in this model critically slows down the writing and reading of data when it is full, which causes lags when applications are launched.

It’s also worth checking which programs are running in the background. Often users don’t notice how the tenth tab of the browser or the suspended messenger continue to consume CPU time. You can use hidden engineering menus or third-party monitoring utilities to get detailed information.

💡

Use the standard Security app for initial evaluation, but don’t rely on its built-in accelerator, as it often just restarts processes that immediately start again.

It's important to distinguish between a lack of RAM and a lack of storage space for files: in the first case, applications are unloaded from memory immediately after they are folded, in the second case, the phone may refuse to install updates or take pictures at all, and proper diagnosis will help you choose the right acceleration strategy.

Cleaning the system from garbage and removing excess

The easiest and most efficient way to get back to speed is to free up space. Remove unused apps you haven't run in the last month. Every application you install, even if you're not using it, can have background services that load the processor.

Special attention should be paid to folders with uploaded files and social media cache. Messengers like Telegram and WhatsApp tend to accumulate gigabytes of media files that are not necessary for the application to work, but take up precious space. Cleanup can be done manually through the file manager, and using built-in tools.

After removing the excess data, it is recommended to reboot the device, which will allow the system to redistribute resources and start the necessary services again, without any excess luggage. If after cleaning the place still runs out too quickly, check the settings for automatic saving in messengers.

Remember the system debris that comes after updates. Older firmware files can stay on the system. More advanced tools may be needed to remove them, but standard cleaning through the Memory menu is often enough for basic maintenance.

Optimization of visual effects and animation

The visuals of MIUI are beautiful, but they require graphics accelerator resources. On Redmi 5, with its modest video core, turning off or simplifying animations can give you a tangible boost in response speed, and for that, you'll need access to a developer menu.

To activate hidden settings, you need to click on the version number several times in the About Phone section. Once the notification appears, the Developer Form will appear in the Additional menu, and that's where the keys to visual performance are hidden.

Inside the developer menu, find the section related to drawing or animation. You're interested in three options: "Window animation," "Jump animation," and "Animation duration." These are set to 1x by default. Change them to 0.5x or completely disable (0x) if you want maximum speed.

This change won't increase the physical power of the processor, but it will create the illusion of faster operation, because the screens will switch instantly. The interface will become more responsive, and the delays when opening folders will disappear. This is one of the safest ways to accelerate.

Managing Autoboot and Background Processes

One of the main reasons for RAM eating away is the autorun of apps. In the Android ecosystem, many programs tend to start immediately after the phone is turned on to alert or update data. On Redmi 5 with its 2 or 3 GB of RAM, this is critical.

Go to the Security app settings (green shield icon) and find the Permissions section, where you can disallow auto-run for most programs, and leave this privilege to messengers and alarms, which should always work.

Also, you should limit background activity for heavy applications, and each program has an activity control setting, and select the option "No background processes" or "Limit background activity," which will prevent the application from running when you've folded it.

Beware, though: too aggressive a restriction can cause you to stop receiving notifications from important services.The balance between performance and functionality is a key point in setting up Android.

Resetting settings and flashing the device

If the software methods don't work, the radical but effective way is to completely reset to factory settings, which will remove all your data, applications and settings, bringing the phone back out of the box, often solving problems that have accumulated over the years.

Before starting the procedure, make sure to back up important contacts, photos and documents. Reset can be done through the settings menu in the "Advanced Settings" section → "Recovery and Reset".

💡

A full Hard Reset deletes all user data. Be sure to back up your computer or the cloud before you start the procedure!

More advanced users may consider installing custom firmware. The official MIUI shell is quite heavy for Redmi 5 iron. Lightweight firmware based on pure Android (AOSP) or optimized builds like LineageOS can do wonders with the performance of older devices.

The flashing process requires unlocking the bootloader, which takes time (usually 7 days of waiting) and carries risks. If you are not confident in yourself, you better limit yourself to a factory reset. But if you are willing to experiment, this will give the gadget a second life.

Maintenance and prevention

Software optimization is only half the battle. The physical state of the smartphone also affects its performance. Overheating is the main enemy of performance. When the processor heats up, the system artificially lowers its frequencies to avoid damage, leading to severe lags.

Check if the speaker and connectors are clogged with dust. If the phone is used frequently during charging or in the sun, it is worth replacing the heat pad inside the case, but this requires repair skills, and an old battery may not give the right current, causing unexpected shutdowns or brakes under load.

Use only original or certified cables and power supplies. Cheap charging can interfere with the touchscreen and cause voltage surges, which adversely affects the power controller. Quality power consumption is the key to stable electronics.

Regularly, at least once a month, reboot your device, which allows you to clear the RAM of fragmented data and start the system processes again, and do not keep your phone on for weeks without interruption.

⚠️ Warning: Don’t install the dubious accelerator apps from Play Market, most of which are viruses or miners themselves, which only put more stress on the system by displaying ads and collecting data.
