Budget smartphone owners often face difficulties in trying to run resource-intensive games. Xiaomi Redmi 9C NFC, despite the affordable price, has modest features, making installing heavyweight projects like Genshin Impact difficult, the process requires careful management of memory and choosing the right version of the game client.
The main challenge is the amount of free space and limitations of the MediaTek Helio G35 processor. Standard download methods from Google Play may not work or lead to errors when updating resources.
In this article, we will discuss all the nuances, from device preparation to graphics customization, you will learn how to circumvent the limitations of internal memory and what alternative download methods exist for owners of devices with low RAM. Following the instructions will help minimize risks and enjoy the game.
Specifications and Features of Xiaomi Redmi 9C
Before you start downloading, it’s important to evaluate the capabilities of your device.The Xiaomi Redmi 9C features 2 or 3GB of RAM and a 32 or 64GB drive. For Genshin Impact, the minimum requirements are significantly higher than the phone’s basic specs, creating a narrow performance neck.
The Android operating system in the MIUI shell also consumes some resources. Background processes, system services and application cache take up precious gigabytes. Without pre-cleaning, installing a game weighing more than 20 GB (taking into account all resources) will become impossible.
- 📱 Processor: MediaTek Helio G35 (8 cores) – requires reduced graphics settings.
- 💾 Memory: Minimum required 15-20 GB free space for comfortable installation and updates.
- 🔋 Battery: 5000mAh capacity will help you survive long gaming sessions, but the heating will be significant.
⚠️ Warning: Trying to install the game without clearing memory can result in a cyclical phone reboot or a complete system lock due to lack of space for temporary files.
It’s worth considering that the NFC version doesn’t affect game performance, but having a communication module sometimes indicates a specific regional firmware build. Global versions of MIUI may have more pre-installed software that will also have to be removed.
Preparing the system for heavy play installation
The first step is to free up as much space as possible. Standard cleaning through settings is not enough. You need to remove unnecessary apps, photos and videos by transferring them to a memory card or to the cloud. The system should see at least 25 GB free for proper decompression of archives.
The second important step is to update the software. Go to Settings → About Phone → MIUI version and check for updates. New patches often contain memory optimizations and security patches important to the operation of gaming services.
☑️ Xiaomi Preparation 9C
It is also recommended to disable automatic updates to apps in Google Play and Mi GetApps during installation, which will prevent the background loading of heavy packs that can interrupt the process of unpacking game files.
- 🗑️ Remove the cache of messengers (Telegram, WhatsApp), they often take several gigabytes.
- 📸 Move all photos and videos to cloud storage or PC.
- 🚫 Turn off gallery sync and other heavy services.
⚠️ Warning: Do not use third-party accelerators from questionable sources, they may contain ads and viruses that will only slow down the Helio processor. G35.
Search and download the installation file (APK + OBB)
Due to the large size of the game, direct installation via Google Play on devices with low Internet speed or unstable connection is often interrupted.The optimal solution for the Xiaomi 9C is to use an official website or a reliable third-party resource to download the full installer.
You’ll need to find an APK file and a folder with OBB data. The official site of the game provides a direct link, but for phones with a small amount of memory, a version with fewer language packs is sometimes better suited if this is provided by a distributor.
Where to look for secure files?
The download process can take considerable time. Make sure the phone is connected to a stable Wi-Fi network. Mobile internet can be unstable and downloads will be interrupted by 90%, which requires a fresh start.
| Source | Advantages | Deficiencies |
|---|---|---|
| Google Play | Automatic updates | Hard to reopen on a cliff |
| Official website | Direct link, current version | You need to manually allow installation |
| TapTap | Optimized versions | Requires the installation of its launcher |
⚠️ Attention: When installed APK browser-based MIUI You need to confirm the action, but you should only do this if the file is downloaded from a trusted resource.
Installation of the game and placement of data files
After downloading the installer, run APK-The system will request permission to install from unknown sources, allow access to the browser or file manager.
A critical point for Xiaomi 9C is the proper placement of OBB files. If you downloaded them separately, you need to manually place the archive or folder on the path of Android/obb/com.miHoYo.GenshinImpact. A mistake in the way will cause the game to launch, but will fly on the logo.
💡
Use Xiaomi’s built-in File Manager Explorer, as it sees Android system folders better in newer versions of MIUI than third-party counterparts.
If you use an SD card, be careful: Modern versions of Android and MIUI restrict writing to system folders on external drives, it is better to place the game in internal memory, even if you have to remove other applications.
- 📂 The Path to the Folder: Internal Memory → Android → obb.
- 📦 The name of the folder should exactly match the name of the game package.
- 🔄 Don't move files. OBB After installation, the game will not find them.
First start and initial loading of resources
When it first launches, Genshin Impact will start pumping additional resources. On Xiaomi 9C, this process can be slow. Don't wind down the game or lock the screen so that the system doesn't kill the boot process in the background.
The login menu may require server selection. Europe server is the best choice for users from CIS and Europe, as it provides the least ping. Asia server can delay, and America can run unstable.
When you preload resources, the phone can get very hot. That's normal for a Helio G35 processor under this load. Remove the case if it's dense, and put the phone on a hard surface for better heat sink.
⚠️ Warning: If the download has got stuck at a certain percentage for more than 10 minutes, don't rush to restart the phone. check for free space - the cache may have grown more than expected.
Optimizing Graphics and Performance
Once you're successful, you'll immediately go to the graphics settings. For Xiaomi Redmi 9C, the only stable game option is the minimum settings. Trying to set the average settings will result in a slideshow of 5-10 frames per second.
Enable Charge Savings within game settings if this option is available in the current client version, and it is also recommended to disable the display of complex effects such as volumetric fog or detailing characters in the distance.
💡
Stable 25-30 FPS on the Redmi 9C is only possible at 720p resolution and minimal graphics settings with shadows disabled.
Using Xiaomi’s Game Turbo mode can give you a small boost in performance. Add the game to the Game Turbo app list via the Security or Games app to prioritize gameplay.
- 📉 Rendering resolution: 0.6 or 0.8 (if available).
- 🌫️ Shadows and smoothing: Turn off completely.
- ⚡ Frequency of frames: 30 FPS (60 FPS squirt).
Remember to close all background applications before launch. RAM of 2-3 GB is barely enough for the game itself, and any unnecessary process in the background will cause a crash.
Possible mistakes and ways to solve them
The most common problem is the "Not enough space" error, even if files seem to fit, because the system needs time to unpack, and the solution is one: free up more space, or use the external card as a storage for a photo to free up internal memory.
Another common mistake is, "Resources failed." This often happens with unstable DNS or ad blockers. Try temporarily disabling Private DNS in network settings or changing your Wi-Fi router.
What to do with a black screen?
In some cases, cleaning the cache of the application itself through Settings → Applications → Application Management → Genshin Impact → Memory → Clear the cache. Don’t confuse it with Clear Everything, otherwise you will have to download the data again.
