How to speed up Android on Xiaomi smartphones: from cleaning cache to hidden features MIUI

Even the most productive smartphones Xiaomi over time begin to “slow down”: applications open for a long time, animation twitches, and the battery sits down in half a day. MIUI But don't rush to the service center or buy a new gadget! 90% of problems with slow work are solved software - without disassembling the case and replacing hardware».

In this article, we will discuss 12 working methods of acceleration, from basic (cleaning cache, turning off animations) to advanced (setting up Developer Options, limiting background processes» MIUI — All instructions are tested on models from Redmi Note 10 to Xiaomi 13 Ultra, but will also be suitable for older devices (provided the current version of the firmware).

⚠️ Warning: If your smartphone is slowing down after a fall, moisture or battery replacement, the problem is more hardware. In this case, software optimization will not help - contact the service center.

To avoid wasting time, first define the bottleneck:

• 🔋 Battery sits down for 3-4 The culprits are background processes and unoptimized energy saving settings.
• 🐢 Do apps take long to open? Is the problem cache or lack of RAM.
• 🎮 We need to turn off the thermal trottling and limit the background tasks.
• 📱 Interface twitching? Helps turn off animation and reset settings MIUI.

1.Cache and garbage cleanup: the first step to speed

App cache and system debris are the main memory eaters, even if you regularly delete files, MIUI It keeps accumulating temporary data that slows down over time:

📌 How to Clear the Cache of All Apps:

1. Go to Settings → Applications → Application Management.

3. Open each application from the top of the list (usually messengers, social networks, games) and click Clear cache.

⚠️ Warning: Do not clear data (Clear all data) - this will delete accounts, settings and saves in games! cache is safe to delete, but after cleaning some applications (such as Google Maps or YouTube) will take longer to load on the first run.

🧹 System Cleaning through Security:

V MIUI There is a built-in tool for deep cleaning:

💡 Hidden function: Security has an optimization option that closes the background. Use it once in a while. 2-3 day, but not more often – the constant forced closure of applications can, on the contrary, increase battery consumption.

💡

If the app is unstable after cleaning the cache (for example, VKontakte does not load photos), just restart it.

2. Disabling animation: making the interface instant

MIUI It's the default for smooth animations when you move between screens, open apps, and fold windows. It looks beautiful, but it slows down the system's response to the screen. 200-500 MS – especially noticeable on budget models like Redmi 9A POCO M3.

3. Limitation of background processes: stop, power consumption!

MIUI It is known for aggressively controlling background processes - but often it works against the user. Messengers (WhatsApp, Telegram) stop sending notifications, and games stop sending notifications (PUBG Mobile, Genshin Impact: They crash when you switch to another screen, and the system continues to waste resources on unnecessary tasks.

⚙️ How to set up background processes:

• 🔄 To save battery: Go to Settings → Battery → Battery mode and choose Balanced (not Energy Saving – it kills performance!).
• 🚫 For speed: In Settings → Annexes → App management open the desired application (for example, Telegram) and turn on: Autorun (allow). Background activity (allow). Show notifications (enable).
• ⚡ For games: B Settings → Special permits → Battery Optimization Find the Game and Choose Without Limits.

🔋 The Secret Trick for Redmi and Poco:

4. Resetting settings MIUI: when nothing helps

If the smartphone slows down even after cleaning the cache and optimization, the problem may lie in the “broken” settings. MIUI. Over time, the shell accumulates configuration errors that are not fixed by standard methods, in which case a soft reset will help - without losing data!

💡

Soft resetting of settings MIUI — The most efficient way to get back to the factory smoothness without losing data. Use it once. 6-12 months of prevention.

5.Memory optimization: what to do if RAM is always clogged

Xiaomi smartphones with 4-6 GB of RAM often suffer from a “memory leak” – when the system does not release RAM after closing applications, as a result, even simple tasks (call, open Chrome) cause hang-ups.

🧠 How to Free Up Working Memory:
