Owners of mobile devices often face a lack of free space when trying to install modern AAA projects. Honkai Star Rail is one of the most resource-demanding games at the moment, and the issue of its physical size on a smartphone’s drive is especially acute. Before downloading, the user needs to clearly understand how many gigabytes will need to be reserved so that the installation process is successful and without errors.
The volume of the distribution is not a static quantity and is constantly increasing with the release of new updates, patches and story chapters. Developers from HoYoverse regularly add high-quality textures, new locations and audio tracks, which inevitably affects the final weight of the application. Ignoring this factor may result in the download being interrupted halfway or the system refusing installation due to lack of space.
In this article we will analyze in detail the current memory requirements, the hidden nuances of data caching and give practical recommendations for preparing your Androiddevice. You will learn how to properly manage game files to save free space for other needs without losing the quality of the gameplay.
Current game size and memory requirements
Currently the minimum amount of space required for installation Honkai Star Rail, significantly exceeds standard indicators for mobile games. The basic client, available for download Google Play or through the official launcher, usually weighs about 20-25 GB. However, this is only the initial stage, since after the first launch the game begins to download additional resources.
The total volume of the installed game, taking into account all loaded language packs and highly detailed textures, can reach 30-35 GB or more. The system Android also requires additional buffer space for temporary files while unpacking archives. Therefore, it is recommended to have at least 40 GB of free memory before starting the procedure.
It is worth considering that different versions of the operating system and file systems may display the occupied space differently. The actual size on disk may differ from the sum of the individual file sizes due to the way data is clustered on your smartphone's storage.
⚠️ Attention: Do not attempt to install the game if you have less than 35 GB free. Even if the bootloader allows the process to start, a critical lack of space during unpacking can lead to damage to the game files and the need for a complete reinstallation.
Size growth dynamics with updates
Size Honkai Star Rail does not remain unchanged after installation. With each major patch dedicated to a new version of the game, the amount of data consumed increases. This is due to the addition of new mechanics, characters and expansion of the game world, which require storing new assets on the user’s device.
Updates can come both in the form of full clients and in the form of differential patches. In the first case, the difference in weight can be colossal, while in the second, the system tries to replace only the changed files. However, even when using differential updates, the overall size of the game folder tends to grow due to the accumulation of backups and logs.
Periodic cleaning of outdated resources through the settings of the launcher itself helps to curb this growth. The developers have provided a mechanism for deleting data from previous versions, which allows you to free up several gigabytes of space after successfully installing a new patch.
Use the “Resource Management” function inside the game launcher after each major update to delete files from the previous version and free up to 5 GB of space.
The impact of graphics settings on the space occupied
Many users They don’t know that the choice of graphics quality directly affects how much weight Honkai Star Rail on their device. During installation or in the launcher settings, you can select the level of texture detail: low, medium or high. High quality requires downloading large texture packs, which can take up an additional 5-8 GB of memory.
If your smartphone has limited internal storage, it is wiser to select medium or low texture settings. The visual difference in dynamic gameplay may not be so noticeable, but you will save a significant amount of space for other applications or media files.
You can change these settings not only during the first installation, but also at any time through the resource management menu. This allows you to have a flexible approach to the issue of data storage, loading high textures only when it is really necessary for screenshots or video recording.
| Texture settings | Approximate additional. volume | Impact on FPS | Recommendation |
|---|---|---|---|
| Low | ~0 GB (base) | Minimum | For budget devices |
| Average | +2-3 GB | Moderate | Optimal balance |
| High | +6-8 GB | Significant | For flagships |
| Cinematic | +10 GB+ | Critical | Recording only |
Instructions for proper installation and updating
The installation process Honkai Star Rail on Android requires careful adherence to certain steps to avoid disk writing errors. First you need to download the official launcher or client from the app store. Make sure that you download the file of the exact version that matches the region of your account.
After launching the installer, the game will ask for permission to access the storage. This is a mandatory requirement, as additional data packets will be saved to the device's shared memory, and not just to the application's isolated folder. Denying this permission will result in the installation being unable to complete.
While downloading resources, it is recommended not to minimize the application or lock the smartphone screen. The active screen ensures that the system does not go into power saving mode, which can limit the data recording speed or cut off the network connection.
☑️ Checklist before installation
If the “Not enough space” error occurs during the download process, do not rush to uninstall the installer itself. Try clearing the cache of other applications or transferring media files to an external drive, then click the “Retry” button in the launcher. The process will resume from where it stopped, rather than start again.
⚠️ Attention: Never forcefully interrupt the installation by closing the application through the task manager. This may lead to file desync and the need to completely reinstall the client.
Clearing the cache and optimizing storage
Over time, the game folder may grow due to temporary files and the shader cache. Honkai Star Rail compiles shaders for the specific hardware of your smartphone when you first launch it, and this data takes up space. Regularly clearing outdated caches helps keep the game size within reasonable limits.
For safe clearing, use the launcher's built-in tools. In the game settings menu, find the “Resources” or “Memory Management” section. There will be a button available for deleting unused files that remain from previous versions of the game or downloaded language packs.
It is also worth checking the language download settings. If you only play in Russian or English, make sure that other language packs (Chinese, Japanese, Korean, etc.) are not downloaded. Each additional language can weigh from 500 MB to 1 GB.
Where can I find hidden temporary files?
Temporary game files are often located in the Android/Obb/com.miHoYo.hkrpgoverse or similar folder. However, deleting them manually through the file manager is dangerous - only use the built-in cleaning in the launcher.
Problems with installation on external drives
Many users try to solve the problem of lack of memory by installing Honkai Star Rail on a memory card microSD. However, modern versions Android and the game itself have strict restrictions on working with external drives. Core game files often cannot be transferred to an SD card due to data read and write speed requirements.
Even if your file system allows application transfer, game performance may suffer significantly. Memory cards, especially inexpensive models, do not provide the random read speed needed to quickly load textures and models in the open world.
In some cases, the system allows you to transfer only part of the data, while the main volume still remains in the internal memory. This creates the illusion of freeing up space, but does not fundamentally solve the problem. It is best to use internal storage type UFS 3.1 or higher.
⚠️ Attention: An attempt to forcefully transfer the game to a slow memory card can cause freezes, long loading times and application crashes. It is recommended to store the game only in the internal memory of the smartphone.
Using fast internal memory is critical for stable operation of Honkai Star Rail; external drives are only suitable for storing media files, but not for installing heavy games.
Comparison of versions for different regions
The weight of the game may vary slightly depending on which region you chose when registering your account. The global version, the version for Southeast Asia, the European or American servers have their own characteristics as part of the pre-installed resources.
Sometimes the differences are due to the presence of specific event materials or localizations that are loaded by default. In addition, versions from different application stores (for example, TapTap vs Google Play) may have different archive structures, which affects the final size after unpacking.
When choosing a server, focus not only on ping, but also on the available memory. If you plan to play on multiple accounts in different regions, you will either have to store multiple copies of the game (which will take 60+ GB) or constantly reinstall the client, changing regions.
If you play on different servers, use the "Manage Accounts" function in the launcher, if available, to avoid completely reinstalling the game when changing regions.
How many spaces exactly? do you need for a comfortable game in 2026?
For a comfortable game with a reserve for future updates, it is recommended to have at least 45-50 GB of free space. The game itself will take about 30-35 GB, but the system needs some wiggle room when downloading patches.
Can language packs be removed after installation?
Yes, in the resource settings inside the game you can deselect (uncheck) unnecessary languages and click the delete button. This will free up from 1 to 3 GB of space depending on the number of removed localizations.
Why does the game size increase after each update?
The size grows due to the addition of new content: textures, models, music and scripts. In addition, the game can store backup copies of old files in case the update is rolled back, which also takes up space.
Does the installation affect the speed of the smartphone?
Yes, if there is less than 10% of free space on the disk, the speed of writing and reading data drops, which leads to lags in the game and slowdown of the entire Android system. Always leave a buffer of free space.
How to check the actual size of the game folder?
Go to Phone Settings → Applications → Honkai Star Rail → Storage. It will indicate the exact size of the application and the size of the data (cache) it currently occupies.
