Modern mobile devices have turned into powerful gaming consoles, capable of running projects that until recently were only available for PCs and stationary consoles. If previously an application weighing 50-100 MB was considered the standard, today top titles take up tens of gigabytes of free space. Unreal Engine 5-level graphics, sophisticated high-resolution textures and complex physical models require a huge amount of data for storage.
Many users face a lack of memory precisely because of the desire to install a high-quality action or open-world strategy. Game size now often exceeds 10 GB, and together with the cache and updates can reach 20 GB or more. This imposes certain requirements not only on the storage capacity, but also on the data reading speed, since long downloads can spoil the impression of gameplay. Owners of smartphones with a small amount of built-in memory have to constantly choose between photos and their favorite games.
In this article we will look at heavy games on Androidthat set new industry standards. We will analyze technical requirements, the impact of file size on performance and give tips on optimizing storage for those who want to enjoy maximum quality graphics without compromise.
Why modern mobile games weigh so much
The main reason for the inflated volume of installation files is the desire of developers for photorealism. High-poly character models and environments require detailed textures in 4K resolution, which take up enormous space. In addition, the use of advanced engines, such as Unreal Engine or Unity with support for ray tracing, increases the weight of assets significantly compared to projects five years ago.
In addition to graphics, a significant part of the memory is occupied by audio files. The modern standard is full-fledged voice acting in several languages and a dynamic soundtrack that adapts to the situation in the game. Audio streams in high quality (lossless or close to it) they can take up several gigabytes on their own. If the game offers a choice of audio language within the client, then all tracks are often downloaded in a single package.
⚠️ Attention: When downloading a game from the app store, make sure that you download only the necessary language packs, if such an option is available. Extra audio files can take up up to 3-4 GB of space without any benefit to the user.
It is also worth considering the architecture of modern updates. Many projects use a “live services” system, where the basic version of the game is supplemented with huge patches that add new locations, events and modes. Over time cache size it can grow to twice its original volume. This requires the user to regularly clean the device or have a memory card with a high write speed.
Use the data compression function in the game settings, if available. This can reduce the footprint by 10-15% with minimal loss of texture quality.
Top largest games for Android in 2026
The mobile entertainment market is oversaturated with AAA-class projects that require a serious approach to installation. The leaders in terms of space are traditionally open worlds and shooters with detailed maps. Below is a list of titles that can safely be called “free memory killers.”
One of the brightest representatives of the genre is Genshin Impact. Despite the fact that the game was released several years ago, with each major update it gains weight. A full installation with all regions and voice packs can take up more than 30 GB. This is a real endurance test for mid-segment smartphone drives.
- 🎮 Genshin Impact — open world, elemental magic, weight more than 30 GB.
- 🔫 Call of Duty: Mobile — dynamic shooter, many modes, weight about 20 GB with resources.
- 🏎️ Asphalt 9: Legends — racing with console graphics, weight varies from 5 to 10 GB depending on quality.
- ⚔️ PUBG Mobile —battle royale with detailed maps, the weight of the complete package is up to 15 GB.
The port Diablo Immortalhas become another heavyweight. This game brings the dark atmosphere of the series to mobile platforms, while requiring significant resources. The high quality of rendering of dungeons and spell effects makes it one of the most demanding of disk space. Users are advised to have at least 40 GB of free space before starting installation to avoid errors when unpacking.
Technical requirements and impact on performance
The large weight of the game does not always guarantee high performance, but often correlates with hardware demands. Heavy textures require large amounts of video memory and wide bus bandwidth. If your smartphone has less than 6 GB of RAM, the launch of such titles may be accompanied by freezes long loading of locations.
The processor also plays a key role. Decoding compressed textures and calculating physics in real time falls on the shoulders of the CPU and GPU. Devices based on chipsets Snapdragon 8 Gen 2 and newer cope with this best. However, even powerful hardware can overheat during a long session in a heavy game, which leads to throttling and reduced frame rates.
| Game name | Min. RAM | Recomm. RAM | Disk space | Processor |
|---|---|---|---|---|
| Genshin Impact | 4 GB | 6 GB+ | 30+ GB | Snapdragon 845+ |
| Diablo Immortal | 4 GB | 6 GB+ | 25+ GB | Exynos 9820+ |
| Call of Duty: Mobile | 3 GB | 4 GB+ | 20+ GB | Snapdragon 730+ |
| Asphalt 9 | 2 GB | 4 GB+ | 10+ GB | Any 8-core |
It is important to understand the difference between the minimum and recommended requirements. At minimum settings, the game may start, but the visual component will be greatly reduced, and textures may not be loaded on time. For comfortable gaming in 1080p resolution and higher, it is strongly recommended to have at least 10 GB of free memory above the weight of the game itself. This is necessary for the caching system to work and prevent crashes.
Having a fast drive (UFS 3.1 or 4.0) is critical for heavy games, as it reduces level loading time and prevents micro-freezes when loading textures.
How to free up space for installing heavy games
Before installing an industry giant, you need to do a general cleaning of your smartphone's memory. Standard cleaning tools often don't remove deep app caches or duplicate files. The most effective way is to use specialized utilities or manual cleaning through a file manager with access rights to system folders.
Pay attention to the folder Android/obb. This is where additional data files for games are stored. If you deleted a game but forgot to clean out this directory, gigabytes of space could remain occupied by "dead weight". It is also worth checking the folder Downloads, where installation APK files from old versions of apps are often accumulated.
☑️ Preparing a place for the game
Another effective method is to transfer media files to external media or cloud storage. If your smartphone supports memory cards microSD, use them to store photos and videos. However, remember that running heavy games directly from a memory card is not recommended due to low reading speed, which will lead to long downloads.
⚠️ Attention: Do not delete files from system folders if you are not sure of their purpose. Erroneous deletion of libraries can lead to unstable operation of the operating system or loss of data from other applications.
Features of installation through third-party launchers
Some users prefer to download games not through Google Play, but through official developer launchers or third-party stores. This allows you to control the process of loading resources and choose which language packs or high-resolution textures to install. For example, the launcher HoYoverse for Genshin Impact allows you to delete resources from past versions of events that are no longer needed.
When installing from third-party sources (APK + OBB), it is important to follow the sequence of actions. First, the base APK file is installed, then the OBB archive is unpacked into the appropriate directory. Violating this sequence will cause the game to launch, but immediately crash with a missing data error.
Path for unpacking OBB: /storage/emulated/0/Android/obb/com.package.name/Using download managers can speed up the process of receiving files, especially if the connection is unstable. Such apps allow you to resume downloading after a connection loss, which is critical for files of 20-30 GB. Loading interruption at 99% without recovery is a common problem with standard browsers.
What to do if the game crashes after installation?
Often the problem lies in an incompatible GPU driver version or a damaged OBB file. Try reinstalling the game, first completely deleting the folder with its data in Android/obb.
The impact of updates on the size of the game in the long run
Games as a service (GaaS) are constantly evolving. Developers are adding new seasons, characters and locations, which inevitably increases the overall size of the project. Over time, a game that weighed 5 GB at release can balloon to 25 GB. This phenomenon is known as “code and asset sprawl.”
Regular updates often do not remove old resources, but only add new ones on top. This leads to data fragmentation and inefficient use of space. Periodically completely reinstalling the game can help reduce its size, since a clean installation only downloads the latest files needed for the current version.
Follow news from the developers. Sometimes they release special patches for size optimization or tools for data compression within the game. Ignoring such updates may result in you storing gigabytes of outdated textures that will never be used in gameplay.
⚠️ Attention: App store and launcher interfaces are subject to change. Always check the current methods for managing downloaded resources in the "Settings" section inside the game itself or in the help on the developer's official website.
If you plan to play a heavy game for a long time, consider buying a smartphone with a memory capacity of 256 GB or 512 GB. Versions of 64-128 GB will quickly fill up with the system and a couple of such titles.
Frequently asked questions (FAQ)
Is it possible to transfer a heavy game to a memory card?
Technically, some smartphones allow you to transfer some application data to an SD card through the system settings. However, for heavy games this is a bad idea. The reading speed of memory cards (even Class 10) is significantly lower than the built-in UFS storage. This will lead to the fact that the textures will not have time to load, the game will slow down, and the level loading time will increase significantly. It is recommended to store only media files on the card.
Why does the game weigh more than indicated on Google Play?
The app store often only lists the size of the base APK file. Additional resources (maps, sounds, video screensavers) are downloaded separately after the first launch or during the installation process. In addition, the game creates a cache as it runs, which grows over time. The actual weight may be 2-3 times higher than stated.
How to learn how much space the game will take up before installation?
The exact size can often be found out by clicking the "More" or "About the application" button in the product card on Google Play. It is also worth reading the latest user reviews - they often indicate the current weight after all updates. The 4PDA or Reddit forums also publish exact data on the size of OBB folders for specific versions.
Does deleting the game cache reset my progress?
Usually no. The cache contains temporary files, textures and scripts. Game progress (levels, items, currency) is most often stored either in the cloud (when an account is linked) or in a separate data folder, which is not deleted when clearing the cache. However, before manipulation, it is always recommended to link your account to a social network or email.
Is it worth downloading resources in high quality on a weak phone?
No, this makes no sense. If your smartphone screen has HD+ resolution (720p) or the processor cannot support high graphics settings, downloading 4K textures will only take up space and increase loading time. In the game settings, select the resource download option for “Low” or “Medium” quality to save up to 5-10 GB.
