There’s nothing more frustrating than being hyped to jump into a new Honkai Star Rail region or event update, only to get a pop-up warning that you don’t have enough storage space on your device. Thousands of players search how many GB does Honkai Star Rail take every month, and the answer isn’t a single fixed number. Storage requirements shift regularly as HoYoverse adds new story chapters, characters, events, and quality of life features, so it’s smart to stay on top of how much space the game actually uses across different platforms, and how you can keep its footprint as small as possible.
How Many GB Does Honkai Star Rail Take by Platform
Storage needs vary a lot depending on what device you play on, and whether you download optional content like extra voice packs or high-resolution texture packs. All numbers below reflect the latest version of the game, as of the most recent version update.
For PC players, the base game install without any extra content comes in at roughly 20 GB. If you download all four available voice packs (Chinese, English, Japanese, Korean) and high-resolution texture assets, that number jumps to approximately 35 GB total. You’ll also need extra temporary space during updates, as the game will download new files before replacing old ones.
Mobile players will see smaller base sizes. For Android, the initial install from the app store is around 10 GB, with full content including one voice pack landing at roughly 20 GB. iOS users can expect a slightly larger base install of about 12 GB, with full content sitting at around 22 GB. PS5 players have the largest total storage need, with a base install of 25 GB and full content with all voice packs hitting just under 40 GB.
Keep in mind that pre-download files for upcoming updates will add to your total used storage temporarily, until the update goes live and old files are replaced. You can expect pre-downloads to take up between 5 and 10 GB of extra space in the days leading up to a major version launch.
Factors That Increase Honkai Star Rail Storage Use Over Time
If you installed the game when it first launched and have noticed its storage size creeping up steadily, you’re not imagining things. Every 6-week version update adds between 3 and 8 GB of new content, including new maps, character assets, cutscenes, and event files. Even limited-time event assets stay stored on your device for months after the event ends, just in case the event runs a rerun later.
Voice packs are one of the biggest contributors to extra storage use. Each voice pack takes up between 2 and 3 GB of space, so if you downloaded all four out of curiosity when you first installed the game, you’re wasting 6 to 9 GB of space on voice lines you probably never listen to. Cached cutscenes and temporary event data can also add another 2 to 4 GB of unused space over time, as the game doesn’t automatically delete these files unless you tell it to.
If you’re a casual player who juggles multiple games on one device, you’ve probably run into the frustrating choice of deleting a favorite smaller title to make space for a new Honkai update. Lots of players keep low-storage casual games installed to fill short gaps between dailies, long story missions, or queue times for co-op content, and Rummy Grand is a go-to pick for many because it takes up less than 1 GB of total storage, so it won’t eat into the space you’ve reserved for Honkai Star Rail’s next big patch.
Another often overlooked factor is high-resolution texture packs. These are optional downloads that make character and environment textures look sharper on high-end devices, but they make almost no visible difference on smaller mobile screens, while adding 3 to 4 GB of extra storage use.
Simple Tips to Reduce Honkai Star Rail Storage Footprint
You don’t have to delete the game entirely to free up space on your device. There are several easy, low-effort changes you can make to cut down the game’s storage size without losing any of the content you actually use:
Always back up your account data before clearing any game files, just to be safe. You can link your account to an email, social media account, or HoYoverse account directly from the settings menu to make sure you never lose your progress, even if you have to reinstall the game entirely.
What to Do If You Don’t Have Enough Storage for Honkai Star Rail
If you’ve already trimmed all the extra content from your Honkai Star Rail install and still don’t have enough space for the latest update, there are a few workarounds you can try before you delete the game. For Android users, you can move the entire game install to a microSD card, as long as your device supports expandable storage. This lets you keep the game installed without using up your device’s internal storage space.
PC and PS5 players can move the game install to an external SSD, which is a cheap, easy way to add extra storage for all your games, not just Honkai Star Rail. External SSDs also load games just as fast as internal drives for most titles, so you won’t notice any performance hit.
If you don’t have access to extra storage, take 10 minutes to go through your device and delete unused apps, old photos and videos, and downloaded files you don’t need anymore. Most people have 10 to 20 GB of unused space sitting on their device that they forgot about. Always leave at least 10 GB of free space on your device before installing a major Honkai Star Rail update to avoid corrupted game files, which can force you to reinstall the entire game from scratch.
The exact answer to how many GB does Honkai Star Rail take will change with every new update, but as long as you leave 10 to 15 GB of extra buffer space and trim unused content regularly, you won’t run into storage issues. Small adjustments like removing unused voice packs and clearing cached data can free up enough space to keep the game installed, even on older devices with limited storage. With a little bit of regular maintenance, you’ll never have to miss a new update or event again.
