Why Xiaomi is fast running out of RAM: 10 main reasons and solutions

Have you noticed that your Xiaomi or Redmi is slowing down, apps are constantly rebooting, and the task manager says “Not enough memory (RAM) But what exactly is it eating up and how to get the smartphone back to speed?

In this article, we will discuss 10 main reasons why Xiaomi is quickly spent on the Internet. RAM — silk-like MIUI You'll learn how to optimize memory without drastic measures (like factory resets), which settings should be changed and which applications should be removed. RAM» with specific numbers and a test to determine your problem.

Spoiler: 80% of the time, it's not the crooked firmware that's to blame, but the wrong user habits, but there are technical nuances, like why Xiaomi is so bad. 12T 8GB RAM can slow down more than POCO F5 6GB. Let's get this straight.

1. MIUI Why Xiaomi’s shell eats so much RAM

Shell MIUI — It's both the main advantage of Xiaomi smartphones and their Achilles heel. MIUI aggressively caches applications in the background so they open faster, but often this leads to overspend of RAM.

For example, on the Redmi Note 11 with 4 GB RAM The system can take up to 1.5-2 GB out of the box - and this is without taking into account the applications launched by the user! MIUI It does not always correctly release memory after closing programs, leaving them hanging in the background.

• 📊 How many? RAM eat MIUI? — MIUI 12/13/14: 1,2–1,8 GB (without applications) – HyperOS (new shell): 1–1,5 GB (optimized better)
• 🔄 Why not release? The system thinks that "free" RAM — It's bad, and she tries to fill it with cache.
• ⚡ How do you check? Open the settings. → The phone. → Memory and see the usage schedule.

Unfortunately, you can’t completely disable caching – it’s part of the architecture. MIUI. But you can limit background activity:

Disable auto-run of unnecessary applications|Set a limit on background processes|Turn off animation and visual effects|Upgrade to HyperOS (if available)-->

2. background processes: who hangs in RAM without your knowledge

Even when you're not using a smartphone, there are dozens of processes in its RAM.

• 🤖 System services (com.android.systemui, miui.analytics)
• 📱 Auto-run applications (Facebook, TikTok, instant messengers)
• 🔄 Synchronization (Google Account, Mi Cloud, mail)
• 📡 Location services (maps, weather, fitness trackers)

To see the full list, install the Developer Options app (or enable Developer Mode via Settings). → The phone. → Version. MIUI (tap 7 times) and go to Settings → Additionally. → For developers → Services at work.

Social media (FB, VK, TikTok)|Messengers (WhatsApp, Telegram)|Games (Genshin Impact, PUBG)|Systemic processes (MIUI, Google)|I don't know, I haven't.-->

How to clean up background processes:

1. Open Settings → Applications → Application Management.
2. Select the application → Auto-start → Turn it off.
3. For radical cleaning, use the settings → Memory. → Clean up (but this is a temporary solution).

💡

After cleaning, RAM Memory is quickly clogged again, check your smartphone for viruses using Malwarebytes or Dr.Web Light.

3. Games and "heavy" applications: the main eaters RAM

Games like Genshin Impact, PUBG Mobile or Call of Duty: Mobile can take from 1.5 to 3 GB RAM But it's not just that that that's the problem, even the "normal" apps sometimes behave like monsters:

Critical information: Xiaomi with 4 GB RAM Starting Genshin Impact can cause background apps (including music or navigator) to automatically close down.If you’re playing on a weak device, close everything before you start.

For optimization:

• 🎮 In games, downsize. FPS up to 30-40 fps (in the settings of the graphics).
• 🗑️ Clear the game cache through Settings → Annexes → Warehouse → Clear the cache.
• 🔄 Use the Game Turbo (built-in) MIUI play-out).

4. Viruses and malware: hidden "parasites" in the RAM

If your Xiaomi has started to slow down “for no reason”, and unknown processes hang in the task manager (for example, com.android.system.update or service.host.xxx) – it can be a virus or a mining script.

Typical signs of infection:

• 🔥 Smartphone is warming up without load.
• 📉 The battery is discharged in 3-4 hours (at normal use).
• 🚫 There are pop-ups with ads.
• 🔄 B Settings → Battery visible unknown processes with high consumption.

How to check and delete:

1. Install Malwarebytes or Kaspersky Mobile.
2. Run a deep scan.
3. If the antivirus does not find anything, check the list of installed applications for suspicious ones (for example, “Quick Charger”, “Optimizer”). RAM»).
4. In extreme cases, reset your smartphone to factory settings (Settings) → Additionally. → Recovery and discharge).

5. Updates MIUI and bugs: when the system is "flowing»

Sometimes the cause of overspending RAM They get bugs in the firmware, like when you upgrade to MIUI 14 Many Xiaomi users 11T Redmi Note 10 Pro complained of memory leaks when the system “eat” up to 3 GB RAM for no apparent reason.

How to understand that the problem is in the firmware:

• 📅 The problem arose immediately after the update.
• 🔄 Reboot temporarily helps, but after an hour everything repeats.
• 📊 B Settings → The phone. → Memory can be seen that the system takes up an abnormally large amount (for example, 2.5 GB against the background).

Decisions:

• 🔄 Reverse to the previous version of MIUI (via Settings → System Update → Three Points → Select Service Pack).
• 📥 Install custom restoration (TWRP) And run the clean version. MIUI.
• 📧 Write in support of Xiaomi with logs (how to collect: Settings) → The phone. → All specifications → The core → Long-term press on "Korea Version»).

💡

If you have Xiaomi on HyperOS, memory leaks are less common – this shell is optimized better than the one you’re looking at. MIUI 12–14.

6. Wrong settings: What you do wrong

Many users are causing overspending themselves. RAM, Without even knowing it, here are the 5 most common mistakes:

• 🔄 Developer mode disabled → You can not limit the background processes.
• 📱 Auto-start enabled for all applications → they hang in RAM constantly.
• 🎨 Live wallpaper or animations are used → Eat up to 200-300 MB.
• 🔋 Actively optimized battery for all applications → They don't close completely.
• 📡 Always on. GPS/Bluetooth/Wi-Fi → background services scan them.

How to set it up correctly:

1. Enable Developer Mode and set a background process limit: Settings → Additionally. → For developers → Process limit → Maximum 2-3 process in the background
2. Turn off auto-start for unnecessary applications (Settings) → Annexes → Autostart control).
3. Replace the live wallpaper with static.
4. In the battery settings, select Adaptive Optimization instead of Unlimited.

💡

If you POCO F4 Xiaomi 12 Lite, try turning on Ultra Battery Saver mode – it aggressively closes the background apps, saving you money. RAM charge.

7. Multitasking: Why so many apps hang in the background

MIUI The default is to keep as many apps as possible in memory so they open faster, but on weak devices (from 3-4 GB). RAM) This leads to constant hanging.

How to check how many apps are hanging in the background:

1. Open Recent Apps (swipe up with a delay).
2. Click on the "Secure" icon (pin) → You will see a list of blocked applications from cleaning.
3. Or install the Simple System Monitor from Google Play.

How to limit multitasking:

• 🔄 Turn on the Cleanup. RAM when locking the screen (Settings) → Lock screen → Additionally. → Cleaning up memory).
• 📱 Disable Apps for Unnecessary Programs.
• 🎯 Use the green list in your battery settings to leave only important apps (messaging apps, music) in the background).

💡

Xiaomi 6 on the phone+ GB RAM Multitasking is usually not a problem, but on 3 to 4GB devices, it is best to keep no more than 3-4 apps in the background.

8 Hardware problems: when the "iron" is to blame

If you've tried everything, but RAM It's still clogged - maybe the hardware problem is:

• 🔋 Worn-out battery → The smartphone overheats and the system artificially limits performance, leading to “suspends» RAM.
• 🔥 Processor overheating → triggers the thermal throttling mechanism that resets the cache RAM.
• 💾 Problems with the drive (eMMC/UFS) → Slow memory does not have time to process requests, and the system “hangs».

How to diagnose:

1. Check the battery status through AccuBattery (if the capacity has dropped below 80%, it’s time to change).
2. Install. CPU Monitor and see if the processor is not warming without load.
3. Run a memory test with the help of AIDA64 (storage → Read/write test).

If the problem is hardware, the software won't help.

• 🔧 Contact the service center (especially if the smartphone is guaranteed).
• 📱 Consider the possibility of upgrading to a model with a large volume RAM (for example, POCO X6 Pro 8/12 GB).
