RAM in Xiaomi Redmi phones: everything you need to know about RAM

When you choose a Xiaomi Redmi smartphone or face slowdowns in your device, RAM is one of the key parameters. But what is it in practice? Why does the Redmi Note 12 specs say 6GB or 8GB of RAM, not just "a lot of memory"? And why does even powerful phones sometimes start to "brake" when memory seems to be enough?

In this article, we will understand how RAM affects the speed of Xiaomi and Redmi smartphones, how much memory is really needed for games, social networks and multitasking, and also learn to check the current RAM load and optimize it. You will learn why Redmi models often use virtual memory (RAM Expansion, and how it affects performance, and also, we're going to debunk the myths about "cleaning RAM" and tell you when you really need to worry about memory shortages.

What is RAM in a smartphone and why it is necessary

RAM (operational memory device, or RAM — Random Access Memory is your smartphone's desktop, and it temporarily stores all running apps, background processes, and even interface elements. MIUI. The more RAM – the more tasks the phone can handle simultaneously without hanging.

One example from life is that when you open Instagram, it uploads photos, videos and profile data to RAM, and if you switch to Telegram and then come back, Instagram won't boot from scratch, it'll take data from RAM, but if there's not enough memory, the system will force the background apps to close, and you'll have to wait for the reboot.

• 📱 Multitasking: RAM allows you to quickly switch between applications without rebooting.
• 🎮 Games: Modern Games (Genshin Impact, PUBG Mobile requires 4-6 GB of RAM only for stable operation.
• 🤖 Background processes: MIUI Keeps Google services, notifications, widgets and even preload frequently used apps in mind.
• 🔄 Caching: RAM stores temporary data to speed up reopening applications.

It's important to understand that RAM is volatile memory, and it's cleared when you turn off your phone, as opposed to permanent memory (ROM), So after you reboot, the smartphone works faster: the system starts with a blank slate".

How much RAM does Xiaomi Redmi need in 2026

The amount of RAM depends on how you use your smartphone. For basic tasks (calls, messengers, social networks) will be enough and 4 GB, but if you like games or multitasking, you will have to consider models with 8-12 GB. Here are the current recommendations for the Redmi lines:

Note: In the Redmi budget models (e.g. Redmi) 12C or Redmi A2+) frequently used technology RAM Expansion: It allows you to "get" up to 3-5 GB of virtual memory from the built-in drive, but it is not full-fledged RAM: virtual memory is slower and does not replace physical modules.

⚠️ Note: If the characteristics of Redmi are specified "6+3 GB" or "8+5 GB," which means that 3 or 5 GB is virtual memory. Real performance will be lower than a full-fledged model. 8 or 12 GB RAM.

For most users, 8GB of RAM is the best choice – it will last for 2-3 years of active use. If the budget is limited, you can consider 6GB, but only in models with Snapdragon chipsets. 6xx Dimensity 700 (which is better optimized for memory).

How to check the RAM load on Xiaomi Redmi

To find out how much RAM is currently in use, you do not need to install third-party applications. MIUI There are built-in monitoring tools. Here's how to use them:

1. Open the Settings. → The phone. → Memory (or Settings) → Annexes → Memory status in new versions MIUI).
2. At the top of the screen you will see a graph of RAM usage broken down by application.
3. Click on the More (or graph icon) to see a list of processes consuming memory.

You can also use the hidden developer menu for more information:

Settings → About Phone → MIUI version (click 7 times to activate Developer Mode)


Next: Settings → Additional → For developers → Memory

This menu shows:

• 📊 Average RAM Use in the Last 3 Hours.
• 🔄 The amount of free memory in real time.
• 📉 Consumption schedule by application (can be sorted by decrease).

If the free memory is constantly less than 1 GB, this is a signal that the smartphone needs optimization or updating. Normally, 1.5-2 GB should remain free (for 6-8 GB of RAM).

Close background applications manually

Disable the autoload of unnecessary programs

Clear the cache in Settings → Storage

Reboot the phone

Check for viruses (e.g., Google Play Protect)

Why RAM is clogged even on the new Xiaomi Redmi

Many users complain that even after buying a new Redmi Note 12 or Redmi 13C RAM fills up quickly and the phone starts to slow down. There are several reasons, and not all of them are due to a lack of memory:

1. Background processes MIUI: Xiaomi’s shell actively uses RAM to preload frequently used applications (e.g. Camera, Gallery, Browser) to speed up work, but sometimes leads to excessive consumption.
2. Autoloading: Many apps (especially Chinese ones like ShareIt or Mi Video) are added to the startup and hang in the background, even if you don’t use them.
3. Poor game optimization: Some games (such as Free Fire or Mobile Legends) don’t free up memory after closing, leaving “junk” processes behind.
4. Viruses and Adware: If RAM is clogged for no apparent reason, check your phone for suspicious apps (especially if they are installed from unknown sources).

Another common problem is memory leaks in older versions. MIUI. For example, in MIUI 12.5 was a bug that allowed Google Play Services to take up to 1.5GB of RAM in the background.

⚠️ Note: If after cleaning the RAM (through Settings) → Memory. → Clear) the memory clogs again in 5-10 minutes, which is a sign of a system problem. Try resetting to the factory settings or reflashing the phone.

Xiaomi is also actively using memory compression in new chipsets (for example, Snapdragon 7).+ This allows you to "pack" unused data into RAM, making room for active tasks. G85) This can lead to lags.

How to clean RAM on Xiaomi Redmi: working ways

If your Redmi is slowing down, don't rush into buying a new phone, often optimizing your RAM usage.

1.Manual cleaning through menu MIUI

The easiest way is:

1. Open the Settings. → Annexes → Status of memory.
2. Click Clear Memory (or Clean at the bottom of the screen).
3. Confirm the action.

This will close all background processes, but will not delete application data.

2. disable autoloading of unnecessary applications

Many programs start automatically when you turn on your phone, to turn them off:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Mi Browser or Facebook).
3. Press Autostart and turn off the option.

3.Use of the performance mode

V MIUI There is a hidden function to optimize memory:

Settings → Battery and Performance → Performance Mode → Select “Extreme Performance”

This mode limits background processes and allocates more resources to active applications.

4. Deletion of cache and junk files

The cache of applications can take up to 1-2 GB of RAM. To clear it:

1. Open the Settings → Storage.
2. Select Cache Data and click Clear.
3. For individual applications: Settings → Annexes → [Select an application] → Warehouse → Clear the cache.

💡

If the phone still brakes after cleaning the RAM, try turning off the animation of the interface. → For developers, set all animation parameters on Animation disabled (0x).

5. Phone reboot

It's a banal but effective way.

• 🔄 RAM is cleared.
• 🗑️ All background processes are closed.
• 🛠️ Reset temporary system errors.

It is recommended to reboot Redmi at least once every 2-3 days, especially if you are actively using the phone.

What not to do

Many people recommend using “radiation optimizers” from Google Play (such as Clean Master or Google Play). DU Speed Booster, however:

• ❌ These applications consume RAM and battery themselves.
• ❌ They often show false warnings about a “critical state of memory".
• ❌ V MIUI already have built-in cleaning tools - third-party utilities will not give the advantage.

💡

Cleaning RAM manually is only necessary if the phone is noticeably slowing down. Constant "cleaning" of memory, on the contrary, can reduce performance, as the system will waste resources on rebooting data.

Virtual memory (RAM Expansion) in Xiaomi Redmi: pros and cons

In the latest models of Redmi (starting with Redmi Note 11) appeared feature RAM Expansion is a virtual extension of RAM due to internal memory. For example, in the Redmi Note 12 Pro with 8 GB of RAM, you can add another 5 GB of virtual memory, totaling 13 GB.
