How to speed up Xiaomi Redmi 7A phone: expert guide

Budget Redmi 7A at one time became a hit sales due to excellent price-performance ratio, but time takes its toll, and owners begin to notice the slowdown of the interface. Snapdragon 439 and 2 or 3 GB of RAM quite coped with the tasks of 2019, but modern heavy applications and the updated shell of MIUI create a serious load on the iron. If your smartphone began to slow down, open applications for a long time or freeze when typing, it does not always mean that it is time to buy a new device.

There are many software methods that can significantly improve the responsiveness of the system without losing warranty or complex reflashing. We will look at proven optimization methods, from basic cleaning to hidden developer settings that really change the speed of the interface.

In this article, we will go into detail every aspect of optimization so you can choose the best methods for your situation. Remember that a comprehensive approach often gives you better results than a single procedure.

Analysis and cleanup of system resources

The first step to speeding up any Android smartphone, including the Redmi 7A, is to deep-clean up the accumulated digital dust. Android is prone to accumulating app cache, temporary files and remnants of remote programs that take up precious space and slow down data reading. The standard security utility preinstalled in the MIUI shell is a powerful tool, but its functionality is often underestimated by ordinary users.

Launch the Security app and click on the big green button to scan the system. Once you have completed the check, the system will offer to remove the garbage, but do not rush to agree immediately. Click on the "Clean" option to manually select which categories of files will be deleted, since the automatic mode can miss large files of the messenger cache. Pay special attention to the "Apps" and "Big files" sections, where gigabytes of unnecessary data are often hidden.

In addition to the standard cleaning, it is important to manually check the Downloads folder. Often users forget about downloaded APK installation files, documents and images that are automatically saved from chats, deleting this data frees up space for virtual memory, which is critical for low-end devices with a small amount of built-in storage.

• 🗑️ Use the built-in Explorer app to search for files larger than 100MB.
• 📱 Turn off autoloading media files in WhatsApp and Telegram in the settings of the apps themselves.
• 🔄 Clean your browser cache regularly if you actively use web surfing.

⚠️ Warning: When cleaning the WhatsApp cache, be careful: you may lose important saved images and documents if they were not copied to the cloud.

Managing Autoboot and Background Processes

One of the main reasons why Xiaomi Redmi 7A It starts to run slower over time, and there's an excessive amount of applications running automatically with the system, and each application consumes RAM and CPU time, even if you're not using it at the moment. MIUI There is a built-in autoload control mechanism that needs to be configured.

Go to the Security settings, select the Permissions and search for AutoRun. Here you will see a list of all the programs that start with your phone. Leave only vital services such as alarms or instant messengers on if you are critical to instant notifications. All other apps, especially stores, games and news aggregators, should be turned off.

It's also worth checking the battery settings for each heavy application. Android can aggressively close the background processes, but it's sometimes helpful to manually limit background activity for programs you rarely use, which will prevent them from running hidden and storing in memory, which is especially true for devices with 2 GB of RAM.

Remember that some system services can also consume resources. If you don't use certain features like Bluetooth, NFC or geolocation, keep them off. Constantly searching for networks and satellites loads the processor and speeds up discharge, which indirectly affects performance when battery power is low.

Visual optimization and animation of the interface

Visual effects like smooth window openings and transitions between screens make a pleasant experience of using a smartphone, but they are also one of the main consumers of GPU resources. On budget devices like the Redmi 7A, rendering complex animations can take a noticeable time, creating the illusion of lags and delays. Fortunately, these effects can be easily turned off or accelerated.

To access the animation settings, activate the developer mode. Go to Settings → About Phone and quickly click 7-10 times on the MIUI Version until you notice that you have become a developer.

Inside the developer menu, scroll down to the "Drawing" section. Find three options: "Window animation," "Switch animation," and "Duration animation." These are set to "1x" or "Animation enabled." Change to 0.5x for acceleration or turn off animation altogether (select "No animation") if you want maximum performance.

• ⚡ Setting the value 0.5x Makes the interface visually faster while maintaining smoothness.
• 🚫 Completely disabling animations can make the interface twitchy, but as fast as possible.
• 🎨 The shutdown of live wallpaper also significantly reduces the load on GPU.

The changes take effect instantly, and you'll notice that the windows start opening almost instantly, and this is one of the most effective ways to create a sense of performance on the old hardware without the risk of damaging the data or the system.

Freeing up RAM and working with SD-card

RAM is a narrow neck in the performance of the Redmi 7A. When free RAM becomes scarce, the system begins to actively use the paging file on the internal drive, which speeds are much lower. This leads to noticeable slowdowns when switching between applications. Regularly cleaning the memory through the menu of recent applications (the menu button or swipe) helps, but there are more effective methods.

Using a microSD card can help or hurt. If you store thousands of small files (photos, documents) on a card, the system can index them for a long time, which slows down. Moreover, cheap memory cards have low read/write speeds, and if they have applications installed or cache stored, the phone will work slowly. The ideal solution is to transfer all media files to the card, and the applications and system cache are left on a fast internal drive.

It is recommended to format the memory card as internal storage only if it has a high speed class (U3, A1, A2). Otherwise, use it only as a portable medium, it is also worth checking which applications are most occupied by memory, and if possible move them or delete them.

Desktop widgets, especially those that are updated in real time (weather, news, currency rates), constantly wake the processor to download new data. Removing unused widgets is an easy way to reduce the load on the CPU and free up RAM.

Use of Lite versions of applications

Modern versions of popular social networks and instant messengers have become incredibly heavy.The Facebook app, Instagram or even the main WhatsApp client can take up hundreds of megabytes in memory and require significant computing power to scrolle through the tape. For the Redmi 7A with its modest processor, this is a serious test. The solution is to switch to lightweight versions of programs.

Messenger Lite, Facebook Lite, TikTok Lite, and similar versions of other apps are designed specifically for devices with limited resources and slow Internet access, which consume less RAM, take up less space and load less processor when working, the functionality is often cut down, but the basic functions (messages, tape, calls) work more stable and faster.

Installing such versions often works wonders with performance. For example, replacing regular YouTube with YouTube Go or using Opera Mini browser instead of heavy Chrome can significantly speed up the phone as a whole. Browsers with built-in data saving mode also compress traffic and the load on page rendering.

• 📉 Lite versions are available in 5-10 less space than full analogues.
• 🔋 They consume much less battery power.
• 🚀 Running and running applications are noticeably faster on older processors.

If you can’t find the Lite version on the Google Play Store (as Google is gradually abandoning this format in favor of the main apps), you can use trusted third-party app stores or official developer sites, observing security measures.

Resetting settings and radical methods

If software optimization, cache cleaning, and easy application installs fail to deliver the desired results, the last and most effective method is a complete factory reset. Registry errors, residual file conflicts, and data fragmentation accumulate over time that cannot be eliminated by a conventional cleaning. Resets the phone back out of the box.

Before you do this, make sure to back up all your important data: contacts, photos, documents and application lists. Use the built-in Mi Cloud or Google Drive cloud, and copy files to your computer. Once reset, you can only recover data from the saved copy.

To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The phone will reboot and start the cleanup process, which can take 5 to 15 minutes. Once turned on, you will get a clean system that will work as fast as the iron allows.

⚠️ Warning: Do not restore backup applications wholesale after reset. Install only the most necessary programs manually. Restoring dozens of old applications along with their debris can slow down the system again in a short time.

💡

Full reset is the most effective way to remove software lags caused by accumulated debris and system errors over the years of use.

Once you have reset your phone, it is recommended to immediately apply all the optimization tips described above: disable autostart, reduce animations and install lighter versions of the applications. This will consolidate the result and ensure the long and fast work of your Xiaomi Redmi 7A.
