Installing heavy modern games on budget smartphones often turns into a real quest, especially when it comes to such a demanding project as Genshin Impact. the owner of Xiaomi Redmi 9 faces a number of limitations: not the most powerful processor MediaTek Helio G80, screen resolution and, most critically, the amount of internal memory. However, to launch the game is still realistic, if you approach the issue competently and prepare the device for serious load.
In this article, we will discuss in detail not only the process of downloading the game client, but also the necessary preparatory steps, without which stable work on Redmi 9 is impossible. You will learn how to free up space, what graphics settings to set for a comfortable game, and how to avoid typical errors when installing updates on devices with a MIUI shell.
Before you get into action, it’s important to understand that Genshin Impact is a game that requires a constant Internet connection and significant system resources. On Redmi 9 without extended memory and proper optimization, you can face long downloads or departures. Let’s prepare your gadget for an adventure in Teivat.
Checking system requirements and characteristics of Redmi 9
The first step before downloading is to soberly assess the capabilities of your device.The Xiaomi Redmi 9 smartphone is equipped with a MediaTek Helio G80 processor and 3 or 4 gigabytes of RAM depending on the version.The official minimum requirements of the game recommend Android version 7.0 and above, as well as a minimum of 3 GB of RAM, which formally corresponds to the characteristics of our phone.
However, the minimum requirements do not guarantee comfortable play at high settings: the game weighs more than 20 GB after full installation with all resources, which is the lion's share of the standard storage capacity of 64 GB. You need to make sure that you have at least 15-20 GB free so that the system can function properly and cache data without failure.
Helio G80 processor can heat up under load, which will lead to trottling — a decrease in frequency to protect components. This is normal for this class of devices, but requires attention to operating conditions during gaming sessions.
💡
The Redmi 9 formally meets the minimum requirements, but requires careful memory and cooling system preparation for stable operation.
Memory Preparation and System Optimization
The biggest problem when installing on Redmi 9 is the lack of free space.The standard 64GB version, after installing the system and applications, leaves the user around 40-45GB. To download and unpack Genshin Impact, you need to free up maximum space. Start by removing unused apps, heavy video files and photo takeups.
The second important step is to clear the cache of system applications, especially Google Play and the browser. Go to the settings, select Apps, find what you want, and click Clear Cache. Don't confuse it with Clear Data, otherwise you'll lose your logins and settings. Also check the Downloads folder, which often accumulates old APK installation files.
If internal memory is critically scarce, consider using a microSD card, although the game itself must be installed in internal storage for proper operation.On Redmi 9, a hybrid slot can be used, but card read speeds may be lower than those of internal memory, which will increase download times.

Ways to download and install the game
There are two main ways to get a gaming client to your smartphone: through the official Google Play store or directly from the HoYoverse developer site. The first option is preferred for most users, as it provides automatic updates and compatibility checks. However, if the game is not available in your region or Google Play gives an error, you will have to use an alternative method.
To install from Google Play, simply type in the search for “Genshin Impact” and click “Install.” Make sure you’re connected to Wi-Fi, as the original file weighs several gigabytes. Once the basic package is loaded, the game will start downloading additional resources within the app, which can take a considerable time.
If you decide to download APK-file from the official site, you will need to allow installation from unknown sources. MIUI You are strictly monitoring security, so when you try to run the installer, you will receive a warning. Follow the instructions on the screen to give permission to a particular application (browser or file manager).
- 📥 Google Play: The safest and easiest way, updates come automatically.
- 🌐 Official website: Allows you to download the game if it is hidden in the Play Market for your device.
- ⚠️ Third-party sites: Not recommended, high risk of virus infection or getting a modified client with a ban account.

Resource loading process and initial setup
After installation of the basic APK-If you download a file or complete a download from the store, the game will start the process of downloading resources. On Redmi 9, this stage can take from 30 minutes to an hour, depending on the speed of the Internet and the speed of memory recording. MIUI Can "kill" background processes to save energy.
When booting, make sure that the phone does not overheat. If the case gets too hot, it is better to remove the case and put the device on a cool surface, such as tiles or glass. Overheating can damage files when recording, and the download will have to start again.
When resources are loaded, the game will suggest selecting a language and logging in to your account. It is recommended to use an email or a third-party service (HoYoverse Account) link to avoid losing progress. Guest login on a long-term basis is dangerous to use.

Optimizing Graphics and Performance
When you run Genshin Impact on Redmi 9 for the first time, you'll be immediately taken to the graphics settings menu. It's crucial for this device to set the settings correctly to get a playable FPS (frames per second). By default, the game can select the mid-settings that will lead to a slideshow on the Helio G80 processor.
In Graphics, select Low or Medium quality. Rendering resolution is better set at 0.6 or 0.8 from native if available in your version, or simply leave the standard screen settings but lower the detail. Turn off shadows, smoothing (Motion Blur) and reduce the drawing range (LOD).
Also in the phone settings, in the About Phone section → click on the MIUI version several times to open Advanced Settings. You can find MIUI Optimization (in some versions hidden) or use No Limits mode for the background activity of the game so that the system does not close it when you switch tabs.
⚠️ Warning: Do not set maximum graphics settings on Redmi 9.This will not only lead to lags and friezes, but also cause strong heating of the case, which can reduce battery life and lead to trottling of the processor, making the game uncomfortable.
For extra performance, you can use Xiaomi's built-in Game Turbo. Add the game to the list, select a performance profile, and disable notifications during the game. This will drain the CPU resources specifically for gameplay.
💡
The optimal balance for Redmi 9: low graphics settings, off shadows and smoothing, which will give a stable 30-40 FPS.
Solving problems and start errors
Even after a successful installation, Redmi 9 users may encounter errors, and one of the most common is “Not enough memory” when upgrading, even if there seems to be space, which is because the system needs space for temporary files when unpacking, the solution is one: free up another 2-3 GB by deleting temporary files or messenger cache.
Another problem is crashes when you load the world or log in to the menu, often due to overflowing RAM, close all background applications through the menu of running tasks before starting a game, and rebooting your smartphone before a game session helps to reset the system cache.
If the game is stuck on the HoYoverse logo, check the Internet connection, sometimes it helps to change the DNS settings in Wi-Fi to public Google servers (8.8.8.8) or switch to mobile Internet for the initial stage, after which you can return to Wi-Fi.
⚠️ Note: If the game crashes with a black screen immediately after the logo, try changing the font size in the developer settings (if enabled). DPI, Although Redmi 9 rarely requires it, it's more often solved by reinstalling the application with a complete data cleanup.
In case of persistent performance issues, you can try to disable animations in the developer settings by setting the scale of animation windows and transitions to 0.5x. This will make the system interface more responsive and free up some CPU resources for the game.
