If you’re a gacha game fan eyeing Honkai Star Rail’s latest limited character banner or new story arc, you’ve probably double-checked your device’s remaining storage before hitting download. Nothing kills excitement faster than a mid-install error telling you you’re out of space, especially when you already planned to spend your evening grinding for your favorite 5-star character. If you’re asking how much gb does honkai star rail take, you’re in the right place for up-to-date, platform-specific numbers plus easy fixes if you’re running low on space.
How Much GB Does Honkai Star Rail Take Across PC, Mobile, and PS5?
The game’s total storage footprint varies a lot by device, and the initial download size you see on the app store or launcher is almost always smaller than the final installed size. That’s because the game unpacks compressed files during its first launch, and you’ll usually need to download extra resource packs to access all content.
For PC players, the base initial download is roughly 20GB, but the fully installed game with all default resources sits at around 28GB as of the latest version. If you download all four available voice packs, that number can jump to 34GB total. Mobile players on iOS or Android will see a 8-10GB initial download, with the full installed size landing between 17GB and 22GB depending on your device’s default texture settings. PS5 players can expect a full install size of roughly 31GB, with no extra unpacking required after the initial download finishes.
Always keep at least 10GB of extra free space on your device before installing a new HSR update to avoid corrupted files or failed downloads, even if the update itself is only advertised as 2-3GB. Pre-install files take up extra temporary space that many players forget to account for.
Factors That Increase Honkai Star Rail’s File Size Over Time
Many players notice their HSR install grows by 3-8GB over the course of a few months, even if they don’t intentionally download extra content. Several common factors drive this extra storage usage, including:
You don’t have to delete all of these to free up space, of course. If you love replaying your favorite character story cutscenes, keeping cached files will save you from re-streaming them every time you want to rewatch. But if you’re tight on space, clearing these unused files can free up 3-7GB of storage almost instantly. You can manage cached data directly in the HSR in-game settings menu under the “Resource Management” tab, no third-party apps required. A lot of players look for tools to help them manage game storage across multiple titles, especially if they play multiple gacha games that take up lots of space. Casual players who switch between HSR and other casual games during short daily breaks often use Royal Yono Vip to track their storage usage across all installed games and get alerts when they need to clear space before a new update drops.
Easy Tips to Reduce Honkai Star Rail Storage Usage Without Losing Progress
You don’t have to delete your favorite photos or other games to make space for HSR, even if you’re running on a 64GB mobile device. A few simple tweaks can cut down the game’s storage footprint by nearly 30% with no noticeable impact on your gameplay experience.
First, delete any voice packs for languages you don’t use. Most players only stick to one or two voice languages, so deleting the other two can free up 4-6GB of space immediately. Second, lower your texture quality if you play on a small mobile screen. Most people can’t tell the difference between high and medium texture settings on a 6-inch phone, but this tweak can cut 2-3GB from your install size. Third, clear cached event data every 2-3 months after limited events end, since you won’t be able to access that content again anyway. Fourth, wait to download pre-install resources until 24 hours before the update goes live if you’re tight on space, so you don’t have extra unused files sitting on your device for days.
None of these storage reduction tips will affect your saved progress, account data, or earned items, so you can test them out without worrying about losing anything you’ve worked for. If you ever want to restore deleted content later, you can redownload any voice pack or resource pack directly from the in-game settings menu for free.
What Happens If You Don’t Have Enough Storage for Honkai Star Rail?
A lot of players brush off storage warnings, assuming they can just delete a few random apps mid-download to make extra space, but that often causes more problems than it solves. The most common issue you’ll face is a failed download that wastes your mobile data, especially if you’re not connected to wifi. If the download is interrupted halfway, you’ll usually have to restart it from scratch, which can take hours on a slow connection.
Worse, interrupted downloads can corrupt core game files, forcing you to uninstall and reinstall the entire game to fix the issue. That’s an even bigger hassle if you have limited data, since you’ll have to download all 20+GB of the game again. You might also face random crashes mid-battle, which can cost you clear runs of endgame content like Forgotten Hall or Simulated Universe when you’re seconds away from beating a difficult boss.
If you get a storage error mid-download, cancel the download completely before clearing space to avoid corrupted files, then restart the download once you have enough free space. Never interrupt a HSR update once it’s past the 50% mark unless you have no other choice, as this is the most common cause of corrupted save data that requires a full reinstall. If you play on Android, you can also move the entire game install to an SD card if your device supports it, which gives you extra space without deleting any content.
At the end of the day, knowing how much gb does honkai star rail take for your specific platform can save you a lot of frustration when you’re excited to jump into a new update or character banner. You don’t need to splurge on a new device or delete all your other apps to make space for it either – a few quick tweaks to your resource settings can free up more than enough room to keep HSR installed long term. If you’re still running low on space after trying these tips, you can always use cloud gaming services to stream the game if you have a stable internet connection, though most players prefer the native install for faster load times and no lag during intense battles.
