Modern mobile devices have turned into powerful gaming consoles, capable of running projects that were only available on a PC a few years ago. However, behind the new generation graphics and open worlds lies the other side of the coin - a colossal amount of space occupied. Users are increasingly faced with a situation where, after downloading just one installation file from Google Play, the device displays an out of memory error.
This happens because many developers use the technology of loading additional resources. A basic APK file can weigh only 100 MB, but after launch the game begins to download gigabytes of textures, models and audio tracks. Total weight Such projects often exceed 10 and sometimes 15 gigabytes, which makes up a significant part of the internal storage of even top smartphones.
Owners of gadgets with a memory capacity of 128 GB or less have to carefully plan the installation of such titles. Understanding which games take up the most space can help you free up space or decide to expand your storage in advance. We analyzed the current mobile entertainment market to rank projects that require the maximum amount of free space.
Why modern mobile games take up so much space
The growth in the volume of game files is directly related to the evolution of graphics engines and increasing requirements for content quality. If previously textures were low resolution, and models consisted of a minimum number of polygons, today mobile games strive for photorealism. Using engines like Unreal Engine 5 or advanced versions Unity allows you to create worlds indistinguishable from computer analogs, but you have to pay for this with gigabytes of data.
The bulk of the data is occupied by highly detailed textures and audio files. Developers often include resources for different graphics levels in the package to ensure the game runs on both budget devices and flagships. In addition, modern open worlds require storing a huge amount of data about locations, NPCs and events, which are not generated procedurally in real time, but are pre-written by the authors.
⚠️ Attention: The application size indicated on Google Play often does not include the amount of cache that is loaded after first launch. The actual weight of the game can be 5-10 times larger than the original installation file.
Another factor is localization. Support for dozens of languages, including full audio dialogue for each of them, significantly increases the size of the distribution. Some studios allow you to select language packs separately, but many download the full set by default, taking up extra space on your smartphone's storage. Android-smartphone.
Before installing a heavy game, check the available space with a 20% margin. The system requires free space to unpack archives and create temporary files during updates.
Rating leaders: games with maximum weight
Analysis of the current assortment in application stores has revealed clear leaders in disk space consumption. These projects set the bar for quality, but require the user to take a serious approach to memory management. Below is a list of titles that consistently rank at the top of the rankings in terms of data usage.
- 🎮 Genshin Impact is one of the most voluminous projects, whose weight, taking into account all updates and regions, regularly exceeds 20-25 GB on mobile devices.
- 🏎️ CarX Street is an open-world racing simulator that requires the installation of additional high-resolution texture packs, inflating the size to 10-12 GB.
- 🔫 Call of Duty: Mobile is a popular shooter that, when fully loaded, maps, modes and graphics resources can take up more than 15 GB of memory.
- 🌍 Diablo Immortal is a role-playing game from Blizzard, whose assets and high-quality cutscenes occupy an impressive amount of internal storage.
Projects that are constantly growing in size with each season deserve special mention. For example, PUBG Mobile or Honkai: Star Rail over time, gigabytes of unused resources accumulate if the user does not regularly clear the cache within the game settings. Without timely maintenance, such applications can “eat up” all the free memory of the device in a few months of active play.
It is worth noting that the record holder is often not the game itself, but its modifications or user content. In some sandboxes, the total size of the data folder can reach absurd values if the user has downloaded many maps and skins. Therefore, when assessing free space, it is important to take into account not only system files, but also user data.
Technical installation features and caching
The process of installing modern heavy games on Android is significantly different from installing regular applications. The user is faced with a two-step download: first, the base installation package is downloaded, and then additional data files (OBB or Asset Bundles) are downloaded. Understanding this mechanism is critical for a successful, error-free installation.
A situation often arises when there is enough space to download the installer, but there is not enough space left for unpacking. At the time of installation, the system creates a temporary copy of the files, which temporarily doubles the required amount of memory. If during the process unpacking archives the space runs out, the installation will be interrupted, and the downloaded files may become corrupted, requiring complete deletion and re-download.
| Game name | APK size (approx.) | Data size (cache) | Total weight |
|---|---|---|---|
| Genshin Impact | 300 MB | ~25 GB | ~25.3 GB |
| Diablo Immortal | 200 MB | ~12 GB | ~12.2 GB |
| CarX Street | 150 MB | ~10 GB | ~10.15 GB |
| Warzone Mobile | 400 MB | ~18 GB | ~18.4 GB |
Some games allow you to choose which resources to download. For example, in the settings you can disable the loading of ultra-high-resolution textures or sound packs for languages that you do not use. This can reduce the final game size by several gigabytes, which can be critical for devices with limited storage. Look for the option Resource management in the main menu or chart settings.
Why does the game weigh more after an update?
Often developers do not delete old asset files when updating, but simply add new ones on top. This leads to the growth of the data folder. Some games have a built-in “Clean up obsolete files” function, which should be used after major patches.
How to prepare a smartphone for installing giants
Before attempting to install a project weighing more than 10 GB, you must thoroughly prepare the device. Simply deleting a couple of photos may not be enough. You will need a systematic approach to freeing up space to ensure successful installation and stable application operation in the future.
Start by analyzing the storage through system settings. Go to Settings → Memory (or Storage) and use the built-in cleaning tool. It will help you find large files, duplicates and cache of unused applications. Pay special attention to the folder Download and the cache of instant messengers, which often accumulate gigabytes of media files.
- 🗑️ Remove unused applications, especially heavy games that you haven't played for a long time.
- 📸 Transfer photos and videos to cloud storage or a computer, then delete them from the device.
- 🧹 Clear the cache of all installed applications through the settings menu, this can free up from 1 to 5 GB.
- 💾 Consider using a memory card microSD, if your smartphone supports installing games on external media.
If the built-in memory is critically low, consider resetting the device to factory settings. This is a radical method, but it allows you to remove all the digital garbage accumulated over years of use and get the cleanest possible system. Don't forget to make a complete backup of your important data before this procedure, using Google Account or third-party tools.
⚠️ Attention: Not all games can be transferred to a memory card. Many modern titles require installation strictly into internal storage due to read/write speed limitations and Android security policies.
☑️ Preparing to install a heavy game
Optimizing and managing memory during the game
Even after successful installation, a heavy game will continue to consume space. Over time, the size of the data folder may increase due to logs, temporary files, and new updates. Regular maintenance is necessary to ensure that the game does not crowd out other important applications from your smartphone.
Many modern projects have built-in optimization tools. In the main menu or settings you can often find a button Preloading resources or Delete unused resources. Using these functions allows you to delete data from completed levels or textures that are not used in the current season, freeing up space without deleting the game itself.
It is also worth keeping an eye on updates. Sometimes developers release patches that optimize file sizes, but more often the opposite happens. If you see that the game takes up an abnormally large amount of space compared to the official requirements, try reinstalling it. This will remove the accumulated "garbage" and install a clean version with the latest files.
Regularly clearing the game cache through the Android settings or in-game menu is the only way to control the growth of heavy projects over time.
For advanced users, it is possible to use debugging tools, such as ADBto analyze the real folder size. The command adb shell du -h /sdcard/Android/obbs can show the exact size of OBB files, which will help identify hidden space eaters that are not displayed in the standard memory manager.
The impact of game size on device performance
There is a direct correlation between the weight of the game and the hardware requirements. Heavy games don't just take up space, they actively use RAM and CPU time to stream assets from disk. If your smartphone's storage is filled to capacity, this can lead to a noticeable drop in performance even on powerful devices.
When free space on flash memory runs out, the speed of writing and reading data decreases. This causes micro-freezes, long loading levels and stuttering in dynamic scenes. For stable FPS (frames per second) it is recommended to always leave at least 10-15% of the total memory free.
In addition, heavy games heat up the device more. Long sessions in projects like Genshin Impact or Warzone Mobile lead to intensive work of the memory controller and processor. Overheating can cause throttling - a forced reduction in processor frequencies, which will negatively affect the gaming experience. Ensuring good ventilation and free memory helps minimize this effect.
⚠️ Note: Game requirements may change with new updates and regions. Always check the current requirements on the official project page in the application store before downloading.
Frequently asked questions (FAQ)
Is it possible to delete the cache of a heavy game without losing progress?
In most cases, clearing the cache (Clear Cache) is secure and does not delete your progress as save data is stored separately or in the cloud. However, clearing data (Clear Data) will delete all progress and require you to download the files again. Always check in the settings of a particular game where the saves are stored.
Why does the game weigh more than what is written on Google Play?
The store only indicates the size of the installation APK file. The main content (textures, sounds, levels) is loaded separately after the first launch via the Internet. It is this additional volume that often exceeds the size of the original file by several times.
How to transfer a heavy game to a memory card?
Starting with Android 10, support for transferring applications to an SD card is limited. Many modern games do not support this feature. If there is no "Move to SD card" button in the application settings, then the developer has disabled this, and the game must be in the internal memory.
How much space should be left free for Android to work?
For correct operation of the system and installation of updates, it is recommended to keep at least 2-3 GB free. For comfortable installation and operation of heavy games, it is better to increase this reserve to 5-10 GB to avoid unpacking errors and brakes.
Removing a game deletes all files completely?
Usually yes, but sometimes there may be residual ones in the folder Android/obb or Android/data files. For complete removal, it is recommended to use the built-in uninstaller or third-party cleaning managers that find the “tails” of deleted applications.
