If you’re gearing up to download HoYoverse’s hit turn-based RPG, one of the first questions you’re likely to ask is how much space does Honkai Star Rail take up before you hit that install button. Nothing kills the hype of jumping into a new story chapter or pulling for a limited 5-star character faster than a pop-up warning that you don’t have enough storage left on your phone, PC, or console. We’ve tested install sizes across all supported platforms, accounted for post-install patches and cached data, and rounded up all the info you need to plan your device storage accordingly.
How Much Space Does Honkai Star Rail Take Up On Each Supported Platform
These base install sizes are for the latest game version, and don’t account for extra cached data, voice packs, or pre-installed future update files you might choose to download. We recommend leaving at least 30% extra free space on top of these base sizes to avoid performance issues or failed patch installs:
- PC (Windows): Base install size is around 80 GB, with recommended extra space of 20 GB for future patches and cached cutscene data.
- Android/iOS Mobile: Base install size is between 20 GB and 26 GB, depending on your device OS and whether you download high-definition asset packs. Older mobile devices will automatically download lower-resolution assets to save space.
- PlayStation 5: Base install size is approximately 75 GB, with an extra 15 GB of reserved space for automatic update downloads.
Why Install Sizes Grow Larger After Your First Download
A lot of new players are confused when they check their storage settings a few months after installing the game, and find the total size is 10 GB to 15 GB larger than the base install they originally downloaded. This isn’t a bug, and it’s not extra junk you don’t need, for the most part. Every few weeks, HoYoverse releases version updates that add new story chapters, playable characters, explorable worlds, and event content, all of which add to the total storage footprint of the game. Cached cutscene and battle data also builds up over time as you play, since the game stores recently viewed assets locally to cut down on load times and reduce lag during play sessions.
If you’re someone who plays multiple gacha or casual games on the same device, you’ll probably notice this storage bloat across most of your installed titles, especially ones that get regular content updates. Many players who switch between long RPG sessions and quick casual rounds will even have 777 Game installed for short, low-stakes play breaks that don’t take up nearly as much storage space as large open-world or turn-based RPGs. That said, not all extra storage used by Honkai Star Rail is necessary, and you can safely clear out some unused files to free up space without breaking your game or deleting your saved progress.
Simple Tips To Reduce Honkai Star Rail Storage Bloat
You don’t have to uninstall the game entirely if you’re running low on space, there are a few easy tweaks you can make to cut down the total size by 5 GB to 10 GB in just a few minutes. First, delete any unused voice packs from the game’s settings menu. Most players only use one voice language, so removing the other three can free up to 8 GB of space immediately, with no impact on your gameplay experience.
Next, clear your cached game data from the in-game settings or your device’s storage menu. Cached data is just temporary files the game has stored to speed up load times, and it will re-download only the assets you actually need as you play, so you won’t lose any saved progress or account data. Another quick tip is to skip pre-installing updates unless you have plenty of extra space. Pre-installs let you play the new version the second it launches, but they take up extra space for a few days before the update goes live, so you can wait to download the update on launch day if you’re tight on space. If you play on mobile, you can also choose to download lower-resolution asset packs from the settings menu to cut down the total size by another 2 GB to 3 GB, though you will notice slightly lower visual quality during cutscenes and battles.
What To Do If You Still Don’t Have Enough Storage Space
If you’ve tried all the storage reduction tips above and still don’t have enough space to install or update Honkai Star Rail, there are a few other options you can try before you delete other apps or files from your device. For PC and PlayStation 5 players, the easiest fix is to install the game on an external solid state drive (SSD). External SSDs are affordable now, and you can get a 1 TB drive for less than $50 that will run the game just as smoothly as your internal drive, with no noticeable load time increases.
For mobile players, you can move the game to an external SD card if your device supports it, though not all Android or iOS devices allow app installs on external storage. If external storage isn’t an option, you can temporarily delete other large files or apps you don’t use regularly to make space for the update, then re-download them later if you need to. Just make sure you don’t delete your Honkai Star Rail app data unless you’re sure your account is linked to a HoYoverse account, Google account, or social media account, so you don’t lose your progress when you re-install. Account linking only takes a minute to set up in the game’s user settings, and it’s the best way to protect your progress if you ever have to uninstall and re-install the game for any reason.
At the end of the day, exactly how much space does Honkai Star Rail take up will depend on what platform you play on, how many extra asset packs you install, and how long you’ve been playing the game, but planning for 100 GB of space on PC/console and 30 GB of space on mobile will cover you for at least the next year of content updates. With a few simple storage tweaks, you can easily fit the game on most modern devices without having to delete other apps or files you use regularly, so you can jump into the next story chapter or limited event as soon as it drops.
