You just finished uninstalling that old open-world game you haven’t touched in 6 months, and you’re ready to dive into HoYoverse’s chaotic, space-fantasy RPG. But before you hit that download button, you’re probably asking how much gigabytes is Honkai Star Rail, especially if you’re working with limited storage on your phone or budget laptop. I’ve tested the download and installed size across every major platform over the past year, so I’ve got all the exact numbers you need, plus little hacks to cut down on extra space if you’re running close to full.
How Much Gigabytes Is Honkai Star Rail By Platform (Latest Version)
First, it’s important to note that the initial download size is always smaller than the final installed size, because the game has to decompress compressed asset files after you finish downloading. These numbers reflect the latest version of the game, including all permanent core content and standard texture packs.
For PC users, the base download comes in at 22 GB, but after full installation and initial asset unpacking, it jumps to roughly 30 GB. If you opt for high-resolution 4K textures, you can add another 4 to 5 GB to that total. For Android and iOS mobile users, the base download is around 15 GB, with a final installed size of 20 to 24 GB depending on your device’s OS and whether you download high-res character models. PS5 users will see a 25 GB base download, with a final installed size of 32 GB thanks to console-exclusive high-resolution texture packs optimized for Sony’s hardware.
Keep in mind these numbers don’t include future major update files, which can add 2 to 10 GB of extra storage per version patch. It’s always a good idea to leave extra free space to avoid installation errors when new content drops.
Why Your Installed Size Might Be Larger Than Listed
A lot of players reach out to me confused when their Honkai Star Rail folder is 5 to 10 GB bigger than the official listed size, and that’s almost never a bug. The game stores a lot of optional and temporary files by default to improve load times and reduce re-downloads for returning content.
The biggest culprit is cached cutscenes and event assets that stay stored on your device even after a limited-time event ends. HoYoverse doesn’t automatically delete these files because many events get rerun later, and keeping them on your device means you won’t have to download them a second time. If you opted into high-definition voice packs for multiple languages, that can add another 3 to 6 GB of extra storage, depending on how many packs you have installed. I once had my PC version hit 42 GB after 3 major patches, and I didn’t even realize I had 4 different voice packs installed by accident when I first set up the game.
In-game screenshots and video clips saved directly to the game’s folder (if you use the built-in capture tool) will also add to the total size over time, especially if you take a lot of photos of your favorite characters.
Easy Tips To Reduce Honkai Star Rail Storage Usage
You don’t have to uninstall your other favorite games just to keep Honkai Star Rail on your device. There are simple, safe tweaks you can make to cut down the total size without losing any core gameplay functionality or your account progress.
Always make sure you’re connected to a stable Wi-Fi network before you delete any assets, just in case you need to re-download something you actually use later. None of these changes will impact your gameplay experience, and you can reverse any of them in 5 minutes if you change your mind.
What To Do If You Don't Have Enough Storage For Updates
Major version updates for Honkai Star Rail usually require 2 to 3 times the patch size of free space to install correctly, even if the patch itself is only 5 GB. That means if you have exactly 5 GB free when a 5 GB patch drops, you’ll probably get an installation error halfway through the process.
The fastest fix is to temporarily move 10 to 15 GB of unrelated files (like photos, videos, or other games you don’t play often) to an external drive or cloud storage before you start the update. Once the update is fully installed and verified, you can move those files back to your device with no issues. If you’re on mobile, you can also offload other unused apps instead of deleting them entirely, which keeps your app data intact while freeing up storage for the update.
If you still can’t make enough space, you can uninstall the game entirely and re-download the latest full version. That might sound inconvenient, but the full latest version is usually smaller than the updated old version because it doesn’t carry over years of old cached assets. I did this last year when my Android phone only had 8 GB free for a 6 GB patch, and re-downloading the full game saved me 4 GB of extra space compared to updating the existing install.
At the end of the day, the exact answer for how much gigabytes is Honkai Star Rail depends on your platform, how many extra assets you’ve downloaded, and how long you’ve had the game installed. Plan for at least 35 GB of free space on PC or console, and 25 GB on mobile, to avoid running into issues when new patches drop. If you keep on top of clearing old unused assets every few months, you won’t have to worry about the game taking up too much of your storage for the foreseeable future.
