Modern mobile gaming has reached such a level that handheld devices often catch up with the graphics of consoles of previous generations. However, for photorealistic textures, complex lighting and large-scale open worlds you have to pay with gigabytes of free space and colossal amounts of RAM. Users are increasingly looking for information about which games weigh a lot and whether their specific smartphone can handle it without overheating and freezing.
Developers strive to pack maximum content into the mobile platform, which leads to an increase in the size of installation files to 10-20 GB or more. This creates a serious load not only on the internal storage, but also on the processor with the video core. To enjoy such projects, owners of Android devices need to carefully monitor the technical characteristics of their gadget and promptly carry out system optimization.
In this article we will analyze in detail the list of the most “heavy” projects, analyze their system requirements and give practical advice on preparing the smartphone for installation. You will learn why some titles take up so much space and how to avoid performance problems at critical moments of the gameplay.
Top of the most demanding projects of 2026
Projects of the genre traditionally become leaders in terms of space occupied and resource consumption Open World i.MMORPG. These games require loading huge amounts of data in real time, which dictates strict conditions for drive speed and volume. RAM. Among the undisputed leaders are universes that regularly receive large-scale updates with new locations.
For example, Genshin Impact and its “related” project Honkai: Star Rail have long become the standard of heaviness for mobile platforms. After several years of development and the addition of entire regions, their weight can exceed 30 GB with a full installation of all language packs and high-quality resources. A similar situation is observed with new parts of popular shooters and racing simulators.
⚠️ Attention: Game sizes are constantly changing with each update. Before downloading, be sure to check the current weight in the application store, as developers may add new textures or events that increase the amount of data.
In addition to RPGs, graphic shooters also set a high bar. Projects like Call of Duty: Mobile or PUBG Mobile in maximum settings mode also occupy an impressive place. Developers are introducing ray tracing and improved anti-aliasing technologies, which require additional gigabytes to store assets.
Hardware requirements: processor, memory and cooling
For comfortable play in heavy projects, free disk space alone is not enough. Productivity becomes a critically important parameter. SoC (systems on a chip). Flagship processors, such as the Snapdragon 8 Gen 3 or Dimensity 9300, are equipped with powerful Adreno or Immortalis graphics accelerators, capable of processing complex scenes without a drop in FPS.
However, even top-end hardware can overheat during long sessions. Heavy games load CPU and GPU by 90-100%, causing thermal throttling - automatic reduction of frequencies to protect the crystal. This leads to a drop in performance and lags. Therefore, the presence of a high-quality passive or active cooling system in a smartphone becomes a prerequisite.
The amount of RAM also plays a key role. If 4-6 GB is enough for light casual games, then for modern hits the minimum standard is 8 GB, and the recommended one is 12 GB and higher. This is necessary to store high-resolution textures and quickly load world objects without accessing the slow internal storage.
Use game modes (Game Turbo, Game Launcher) built into the shell of your smartphone. They allow you to reserve part of the RAM specifically for the game and disable background processes.
The table below shows the approximate requirements for running popular heavy games at high graphics settings:
| Game name | Min. RAM | Recomm. RAM | Free space |
|---|---|---|---|
| Genshin Impact | 6 GB | 8+ GB | 25-35 GB |
| Honkai: Star Rail | 6 GB | 8+ GB | 20-30 GB |
| Diablo Immortal | 4 GB | 6+ GB | 10-15 GB |
| Call of Duty: Mobile | 4 GB | 6+ GB | 15-20 GB |
How to free up space for installing large games
Before you start downloading a giant file, you need to audit the internal storage. Users are often unaware of how much space messenger caches, old photos, and forgotten downloads take up. Clearing this data can free up from 5 to 15 GB of space, which is critical for installing a heavy game.
The most effective way is to use the system's built-in tools. In Android settings, go to Storage or Memory. The system will automatically analyze the files and offer to remove garbage. Pay special attention to the folder Download and the cache of social networks such as Telegram or WhatsApp, where years of correspondence and media files can be stored.
- 🗑️ Delete unused applications that you have not used for more than 3 months.
- 📸 Transfer photos and videos to a cloud service (Google Photos, Yandex.Disk) or to a computer.
- 📂 Clear the folder
Android/obbof data from deleted games, which often remain hanging as dead weight. - 🔄 Factory reset your apps if they're taking up an abnormally large amount of space.
It's also worth checking to see if high-definition screen recording is enabled by default, as these videos can take up gigabytes. If you plan to frequently install large titles, consider buying a smartphone with a memory capacity of 256 GB or 512 GB, since 64-128 GB models will become practically unsuitable for hardcore gaming in 2026.
☑️ Preparing storage
Adjusting graphics for stable FPS
Even on a powerful device, setting maximum graphics settings is not always justified. Often the difference between “High” and “Medium” settings is visually invisible on a small smartphone screen, but the load on the system differs significantly. Proper settings allow you to achieve stable 60 or even 120 frames per second without overheating.
In the settings menu of each heavy game there is usually a section Graphics or Display. Here it is recommended to manually disable resource-intensive features such as Anti-Aliasing, high-quality shadows and real-time reflections. These effects are very taxing GPU, but have little effect on the gameplay.
⚠️ Attention: Do not set the frame rate (FPS) higher than what your smartphone screen supports. If the display has a frequency of 60 Hz, setting 90 or 120 FPS in the game will only increase heating without adding smoothness to the picture.
For advanced users, it is possible to use third-party utilities to unlock hidden graphics settings, but this may lead to unstable operation of the application. It's better to use the built-in presets, such as "Smoothness" or "Balance", which the developers have optimized specifically for mobile platforms.
Secret setting in Genshin Impact
In some versions of the game, you can manually edit the graphics.xml configuration file to enable shadows on low settings, which will improve the perception of the depth of the world without greatly impacting performance.
Overheating problems and methods for solving them
Heavy games are a stress test for any smartphone. Prolonged use leads to heating of the case, which causes discomfort when holding the device and reduces the brightness of the screen. In extreme cases, the system may force an application to close to prevent damage to components.
To minimize heat, ensure good ventilation. Remove the case while playing, especially if it is thick or made from materials with low thermal conductivity. Play indoors with air conditioning or near a fan, avoiding direct sunlight on the screen.
There are special accessories - coolers for smartphones, which are mounted on the back panel and actively cool the processor area. Using such a device allows you to play at maximum settings for hours without throttling. This is especially true for e-sports disciplines on mobile devices.
Reducing the screen brightness to 50-70% significantly reduces the heating of the smartphone and saves battery power, without significantly impairing visibility in dark game scenes.
Installation features through different sources
Downloading games over 10 GB via mobile data can take a long time and drain your bandwidth. It is recommended to use a stable Wi-Fi connection. In addition, application stores such as Google Play often download additional resources after the initial installation, which requires double the amount of free space during the installation stage.
When installing through third-party launchers or APK files, it is important to check the integrity of the data. A corrupted cache file (OBB) can cause crashes when loading the world. In such cases, it helps to completely clear the application data through the menu Settings → Applications and reload the resources inside the game itself.
Some games allow you to select the quality of textures when you first launch. If you have a mid-range device, feel free to select “Low” or “Standard” textures. This can reduce the occupied space by 5-8 GB, which is significant for devices with limited memory.
Frequently asked questions (FAQ)
Why does the game take up more space than indicated in Google Play?
In the application store, the weight of only the installation package (APK) is indicated. The main amount of data (textures, sounds, models) is loaded separately after the first launch or completed during the update process. The actual weight may be 2-3 times higher than stated.
Is it possible to transfer a heavy game to an SD card?
Most modern heavy games do not support full installation on external drives due to the low reading speed of SD cards, which causes lags. Part of the cache can be transferred through the Android settings, but the main files will remain in the internal memory.
How do I know if my phone can run a new game?
Compare your processor model and amount of RAM with the official system requirements on the game page. It’s also useful to look at reviews on YouTube, where they test performance specifically on your smartphone model in a specific game.
What to do if the game crashes after 10 minutes?
Most likely, the overheating protection is triggered. Try lowering your graphics settings, closing background applications, and removing the case. If the problem persists, the game version may not be optimized for your processor model.
