Xiaomi phone lays: what to do and how to speed up Android

The situation when the once-quick Xiaomi smartphone suddenly starts to slow down, annoys every user. It seems that the model is still relevant, but the MIUI or HyperOS interface hangs down, applications open for eternity, and scrolling the tape turns into a twitchy slide show. This is not always a sign of breakdown, often the problem lies in software conflicts or overflow of system partitions.

Before you bring a device to a service center or think about buying a new model, it is worth conducting a comprehensive diagnostic. In 80% of cases, system optimization returns the previous responsiveness without unnecessary costs, we will discuss specific steps that will help eliminate the lags on Redmi and Poco smartphones.

Analysis of the causes of slowing down of the system

The first step should always be to understand the root of the problem. Android is a complex ecosystem where many processes compete for CPU and RAM resources, and if the phone is lagging, then one of the components is not coping with the current load.

A common cause is a trivial lack of space: When internal storage is more than 85-90% full, the system loses the ability to efficiently cache data, which causes interface friezes, and it is also worth considering the wear and tear of flash memory: over time, write and read speeds decrease, especially on budget models with memory such as eMMC.

• 📉 Overheating of the processor causes trottling – forced frequency reduction to protect against damage.
• 📱 Background processes of heavy applications (social networks, marketplaces) “eat” all RAM.
• 💾 Covered cache of system services and junk files from remote programs.

⚠️ Note: If the lags appeared immediately after the firmware update, give the phone 2-3 The system performs application background optimization and file indexing, which temporarily loads the device.

Advertising viruses or miners can stealthily use your Xiaomi resources for other people’s tasks. Check the list of installed applications: if you see something strange without an icon or with a name like “System Service” (but not from Google/Xiaomi), delete immediately.

Cleaning up memory and removing system debris

The standard MIUI Security app is the first tool to turn to, but simply cleaning the cache through it doesn't always solve the problem deeply. You have to manually check what takes up the most space.

Go to Settings → Memory and analyze the distribution of data. Often users forget that messengers like Telegram or WhatsApp can take up tens of gigabytes, they store all the videos and photos you have watched, even if you have already seen them.

You can use the built-in Cleanup tool for deep cleaning, and click on it in the Security app and wait for the scan to finish, and it's not just about clicking Clean, but about going to the Big Files section and manually removing unnecessary videos or archives.

• 🗑️ Delete the folder. Android/data from games that have been deleted, where the residual files remain.
• 📸 Move photos and videos to Google Photos or your computer, freeing up your local space.
• 🔄 Clear the data of the downloads application if old ones have accumulated there APK-file.

There is also a hidden feature of complete cleaning available through the engineering menu, but it requires caution. The average user is better off limited to standard tools or third-party utilities like Files by Google, which are able to find duplicates.

Optimization of visual effects and animations

Modern Android shells look beautiful thanks to animations, but they often create the illusion of lag on devices with medium iron. If the phone slows down when switching between menus, it is worth reducing the scale of the animation.

To do this, activate the developer menu. Go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version). Once the notification “You became a developer” will open access to hidden settings.

From Settings → Advanced Settings → For developers, find the section related to rendering. We are interested in three parameters: “Window animation”, “Change animation” and “Duration of animation”. By default, it is 1x.

Changing these settings makes the interface more “twitchy” but visually responsive.The phone starts to respond to touch instantly.This is one of the most effective ways to speed up Xiaomi without losing data.

⚠️ Note: Do not set the animation value in No Animation.This can lead to incorrect closure of applications and loss of unsaved data when folding.

Managing Autoboot and Background Processes

Many apps tend to run with the system and stay in memory, waiting for your action. This is called auto-run. On Xiaomi phones, control of this process is pretty tight, but requires manual adjustment.

Go to Settings → Applications → Auto Run. Here you will see a list of programs that start themselves. Leave only messengers (for notifications) and antivirus on. Everything else - marketplaces, social networks, games - safely turn off.

Also, check your application-specific energy saving settings. Go to Settings → Battery & Performance → Application Activity Control. For heavy programs, you can select No Limits mode if they don’t work properly, but for background services, it’s best to leave Smart Limit.

• 🛑 Turn off auto-run for apps you rarely use.
• 🔋 Set Energy Saving Mode for background tasks that don’t require work.
• 🚫 Ban background work for apps that aren’t needed when the screen is off.

There is a perception that constantly cleaning RAM through a desktop widget is useful. In fact, in modern versions of Android, it only causes applications to restart, which puts a strain on the processor.

Resetting settings and radical methods

If software optimization didn't work and the phone keeps laying, it could be that there's a lot of critical registry errors or file conflicts in the system, and then the solution is to reset the phone completely to factory settings.

Before you do this, make sure to back up your data to your computer or the cloud, and reset will delete everything: contacts, photos, apps, and settings, and it's the nuclear option that puts your phone back out of the box.

You can reset via the menu: Settings → About Phone → Settings Reset → Erase all data. Make sure the battery is at least 50%, or better, charge the device fully. The process can take from 10 to 30 minutes.

After you reset, don't rush to install hundreds of apps at once. Watch the clean phone. If the lags are gone, it's the software problem. If the clean system is slow, it's probably hardware or memory wear.

• 💾 Backup important data before resetting.
• 🔌 Connect your phone to the charger during the process.
• ⏳ Do not interrupt the reset process and do not turn off the phone.

⚠️ Warning: After resetting and initial setup, the system will re-index files and update apps. During the first hours, the phone may warm and run slowly - that's normal.

💡

Tip: After resetting, install the apps gradually, 3-5 pieces a day, monitoring the stability of the work, which will help to identify the "heavy" application if the problem recurs.

When lags are a sign of hardware breakdown

Sometimes, no program dances with a drum can help. If, after completely resetting and installing only basic applications, the phone continues to hover, warm up in a simple or spontaneously reboot, it is about hardware.

Most often, Xiaomi smartphones fail memory controller or the flash memory chip itself, which is typical for models that have been in use for 3-4 years, and the cause can be a bloated battery that creates pressure on the board and disrupts contacts.

Notice the nature of the lags, and if the screen dims but the sound is coming, or the phone responds to latency touches only in certain areas of the screen, it could be a problem with the display or the plume, and in such cases, only diagnostics in the service will help.

💡

If the factory reset does not fix the lag, the 90% probability problem is hardware in nature and requires replacement of components.

Don’t try to disassemble the phone yourself if you don’t have experience.In modern Xiaomi models, replacing the battery or plume requires heating the case and special tools, otherwise it’s easy to damage the screen or break the tightness.
