How to Clear Xiaomi Keyboard Cache: A Step-by-Step Guide

Modern Xiaomi, Redmi, and POCO smartphones have powerful processors, but even these sometimes experience slowdowns in the interface, and one of the most common causes of slowing down typing is a sprawling keyboard cache, which is temporary data that accumulates during use to speed up work, but over time can cause conflicts and errors.

If you notice that the Gboard or MIUI Keyboard keyboard has started to react with a delay, words disappear when printing or the application spontaneously closes, then it's time for maintenance.Cache cleaning is a safe procedure that does not delete your personal dictionaries or saved passwords unless you mix up the buttons.

In this article, we will take a closer look at all the methods available to clean temporary keyboard files, learn how to distinguish cache clearing from full reset, how to forcefully stop the hung input process, and what hidden features of the MIUI shell can help solve the problem.

Why you need to clean the keyboard cache on Android

The Android operating system uses caching to optimize applications. The keyboard is no exception: it remembers frequently used words, emojis, and even temporary clipboards. However, when the volume of this data becomes too large or files are corrupted, performance drops. Instead of instantaneous response, you get a fraction of a second delay, which when you type quickly becomes a tangible discomfort.

In addition, crowded cache can take up precious space in the system partition of memory. On budget models of Redmi with a small amount of internal storage, this becomes a critical factor. Regular cleaning helps to free up resources and extend the life of the device without having to buy a new gadget.

⚠️ Warning: Don’t confuse cache cleaning with data cleaning. If you choose Clear Data, your personal dictionary, autocomplete history, and all of your individual keyboard design settings will be deleted.

There are several scenarios where interference with the input application is necessary, most often users face it after updating the system or the keyboard application itself via Google Play, and the conflict of versions and old files leads to instability.

Standard cleaning method through MIUI settings

The most reliable and secure method that is suitable for all Xiaomi smartphones, including models with HyperOS shells and older versions of MIUI. You do not need third-party programs or root rights.

You can do this in two ways: search in the settings or through the About Phone menu. The first option is faster: just swipe down on the desktop or settings menu to call the search bar, and type in the name of your keyboard (like Gboard or Mi Keyboard).

If the search doesn't work, you can do the classic schema through the settings menu. The path may vary slightly depending on the firmware version, but the logic remains the same. You have to find the Apps item, then the All Apps, and find the right one in the list.

💡

Use the search in the settings by entering “App Management” to get to the desired section faster without wandering through the menu.

Once you've opened the app page, look at the buttons at the bottom of the screen, and there'll be two important options: "Clean" and "Delete," and we're interested in the "Clean" button, which, when you click, will be the action menu.

Select "Clear Cache" and the system will request confirmation of the action, as it affects system files. Once confirmed, you will see a notification of how many megabytes have been released, which usually ranges from 50 MB to 500 MB depending on the age of use of the device.

Cleaning through Task Manager and Developer Menu

Sometimes the standard path through settings may not be available if the keyboard is so hung that the interface is hard to respond to, and in these cases, alternative process management techniques come to the rescue. The MIUI shell provides advanced tools for advanced users.

The first way is to use the Advanced Settings menu, and you can find the Developer section here if you have one activated, and there's a Working Services or Process Statistics section in this section where you can force the keyboard application to stop before you clean it.

The second is for users who are used to using the menu of recent apps, and on some versions of MIUI, if you press the app icon long enough, the "i" icon appears in the menu of recent tasks, and you click on it, you can immediately go to the app properties and clear the cache without going into the general settings.

Also worth mentioning is the Acceleration feature in Xiaomi’s standard Security app, which cleans RAM primarily, but deep cleaning in this app often affects the cache of system applications, including the keyboard, which is a good preventive method.

Changing animation settings or process limits can affect the stability of the entire system, so after cleaning the cache, it is recommended to go back to the developer menu and make sure that you do not change anything extra.

Using ADB for deep cleaning

For users who want to gain full control of their Xiaomi device, there is a method of cleaning through the computer and debugging over USB. This method allows you to clear the cache of even those system applications that are hidden from the average user in the smartphone interface.

First, you'll need to install ADB drivers on your computer and enable USB debugging on the phone itself, which is on the Developer menu, and then you'll have to enter a command into the console after you connect your smartphone to your PC via cable.

adb shell pm clear com.google.android.inputmethod.latin

The above command is designed to clear the cache of a standard Gboard keyboard. If you use MIUI Keyboard, the package will be called differently, for example, com.android.inputmethod.mi. The exact name of the package can be found through the analyzer applications or in the properties of the application on the phone.

The advantage of this method is that it works at the system level, ignoring any graphical interfaces, which is especially useful if the phone is hanging on the screensaver or the sensor is not responsive, but an error in writing a command can cause other important services to stop.

After the command is executed, the terminal will receive a message “Success”, which means successful execution of the operation, and then restarting the device is not necessary, but desirable for correct restatement of system resources.

What to do if the keyboard continues to slow down

There are situations where cleaning the cache doesn't work, the keyboard is still slow, the letters are late, or the app crashes right after launch, in which case the problem may be deeper than just a crowded temporary buffer.

First, check for updates to the keyboard app itself in the Google Play or GetApps store. Developers often release patches that fix compatibility bugs with new versions of Android.

If the updates didn't work, try disabling heavy functions. In the keyboard settings, look for "Themes," "Animation," or "Vibration on Press" sections. Disabling the press animation and using a standard theme without complex graphics will significantly reduce the load on the processor.

• 📉 Reduce the number of active input languages: If you don’t need Chinese, Arabic or Hindi right now, remove them from the active list.
• 🎨 Turn off live wallpaper and heavy themes that may conflict with keyboard rendering.
• 🔄 Try installing an alternative keyboard, such as Microsoft SwiftKey or Yandex Keyboard, to check if the problem is hardware or software.

In a pinch, if nothing works, you can completely reset your keyboard application (“Clear all data”), which will put it back into a post-install state, and you have to reconfigure the language, theme, and retrain it in your type of print, but this often solves the problem of software errors.

Prevention and useful tips for Xiaomi users

In order to avoid the need for frequent cleaning and input problems in the future, you should adhere to a few simple rules for using Xiaomi smartphone. Android system knows how to manage memory itself, but it can be helped.

Do not install questionable themes and fonts from unverified sources. Third-party themes, especially those downloaded from the official MIUI theme store, may contain code that conflicts with the system keyboard.

Reboot your smartphone regularly. Many users stay on their phones for months, using only sleep mode. Rebooting every 3-4 days clears RAM and resets accumulated system errors that are not visible to the eye.

⚠️ Warning: Avoid using accelerators and Cleeners from unknown Play Market developers, often the source of ads and junk files, slowing down the device instead of speeding up.

Also keep an eye on the internal storage, if the memory is more than 90% full, the system starts to run slower, and the caching mechanism crashes. Try to keep at least 3-5 GB free.

💡

Regularly restarting your smartphone and updating apps is the best prevention of keyboard lags, often more effective than manually cleaning your cache.
