Playing Genshin Impact on your phone is a fantastic way to dive into the world of Teyvat wherever you are. But before you get too excited, a big question often pops up: how much space does this amazing game actually need on your mobile device?

The short answer is that Genshin Impact on mobile generally needs around 31 GB to 52 GB of storage space after the full installation, though the initial download from your app store is much smaller. You'll want to have at least 40 GB free to comfortably install the game and make room for future updates.

Why Genshin Impact Is So Big

Genshin Impact isn't just any mobile game; it's a huge open-world adventure with stunning graphics, lots of characters, detailed areas, and ongoing story updates. All of this content takes up a lot of room on your phone or tablet.

When you first download Genshin Impact from the App Store or Google Play, the app itself might look fairly small, often around 300 MB to 600 MB. That's just the launcher! After you open the game for the first time, you'll need to download all the main game files, which can be over 30 GB. Some reports even show the total size for iOS devices reaching around 51.77 GB as of December 2025.

I remember the first time I downloaded Genshin Impact. I saw the small app size in the store and thought, "Great, this won't take up much space!" Then I opened the app, and the real download started, showing a massive number. My jaw dropped a little, and I quickly had to move some photos to my cloud storage to make sure I had enough room for the initial install! It's a common surprise for new players.

The game keeps growing, too. Regular updates add new characters, entire regions like Fontaine and Natlan, and new quests. Each major update can add several gigabytes, pushing the total size even higher. Developers work hard to make the mobile version optimized, but with so much to explore, it naturally needs a lot of space. This is true across platforms, whether you're playing on mobile, PC, or console. If you're curious about playing with friends, you might also wonder: is Genshin Impact cross platform? (Spoiler: Yes, it is!)

How to Manage Genshin Impact's Storage on Your Phone

Dealing with a large game like Genshin Impact means you might need to manage your phone's storage carefully. Here are some tips to help:

• Delete Old Voice Packs: Genshin Impact offers voice-overs in multiple languages. Each language pack can take up a lot of space, often 8-9 GB. If you only play with one language (like English or Japanese), you can go into the game's settings and remove the voice packs for languages you don't use.
• Clear Completed Quest Resources: The game has a feature that lets you delete data from story quests you've already finished. This can free up a few gigabytes, and you can always re-download them if you ever want to revisit those stories.
• Clear Cache: Regularly clearing the game's cache can help remove temporary files that build up over time, freeing up a bit of space and sometimes even helping the game run smoother.
• Choose Basic Resources: When you first download on mobile, you might get an option to download "Basic Resources" instead of "Full Resources." Basic will be smaller, but you'll download quest resources as you play.
• Consider a Larger Phone: If you're a big mobile gamer, especially with titles like Genshin Impact, having a phone with ample storage (like 128 GB or 256 GB) makes a huge difference.

I recently had to go through my phone and delete a bunch of old photos and videos I didn't need anymore, just to make space for a new Genshin Impact update. It felt like a spring cleaning project, but for my phone! It really makes you think about what's truly important to keep on your device. It’s a small price to pay for exploring Teyvat, though.

Genshin Impact is a massive game that offers countless hours of fun, but it comes with a significant storage requirement on mobile. By understanding why it's so big and using the tips above, you can make sure you always have enough space for your adventures in Teyvat.
