You’re hyped to jump into the latest Genshin Impact region update, only to get that annoying pop-up saying you don’t have enough space on your phone. If you’ve ever had to delete half your photo album or uninstall three other games just to run the newest patch, you’re probably wondering how much GB does Genshin Impact take on mobile, and if there’s any way to keep that number under control. I’ve been playing Genshin on my mid-range Android for three years, and I’ve tested every trick in the book to avoid wiping my phone every time a new update drops, so I’m breaking down all the details you need to know here.
How Much GB Does Genshin Impact Take on Mobile By Operating System?
The first thing you need to know is that the number you see on the App Store or Google Play Store is only the base installer, not the full size you’ll need once you log in and download in-game resources. Many players see the 6-8 GB download size and think they have enough space, only to hit an error halfway through installation when the game unpacks all its core files.
For iOS users, the base App Store download is around 8 GB, but once you install the game, download all initial resources, and log into your account, you’re looking at a minimum of 16 GB of occupied space for a fresh install with no extra data downloaded. If you have a newer iPhone with a high-resolution display, the game will automatically download higher-quality texture packs, which can add an extra 2-3 GB to that total.
For Android users, the base Google Play download is slightly smaller at around 6 GB, but full initial install size lands between 15 GB and 17 GB, depending on your device’s processor and screen resolution. Low-cost Android phones with lower display resolution will often have a smaller install size, since the game doesn’t need to download high-res textures that your screen can’t even display. I recently did a fresh install on my iPhone 14 and my Samsung A54 to test these numbers, and the iOS version came out to 16.2 GB, while the Android version was 15.8 GB, both with only English voice packs downloaded and no extra story resources saved. If you’re wondering how much space Genshin takes on your phone long-term, you can expect to add an extra 1-2 GB every month as new content drops.
Why Genshin Impact’s Mobile Storage Size Grows Over Time
A lot of players install the game with 17 GB free, then three months later they get a storage error, and they’re confused why. Genshin Impact’s storage doesn’t stay static after you install it, and that’s not a bug – it’s by design, thanks to how the game updates and saves content. Many players underestimate Genshin Impact mobile storage size when they first install, which is why they get caught off guard by later update errors. The biggest contributors to growing storage size are:
I didn’t know about cached build-up for the first year I played, and my install size ballooned to 27 GB before I finally did a deep clean. That was enough space to fit three other mobile games, so it was well worth the 10 minutes it took to delete the extra files.
Easy Ways to Reduce Genshin Impact Mobile Storage Footprint
You don’t have to delete half your phone’s content just to keep up with Genshin updates. I’ve tested all these methods on both iOS and Android, and none of them will cause you to lose game progress or lock you out of content you already own. These small tweaks can cut your Genshin Impact mobile install size by up to 40% without any impact on your gameplay experience.
The fastest way to free up space is to delete unused voice packs. You can do this right in the game by going to Settings > Language > Voice Over, then select the voice packs you don’t use and tap delete. If you only ever use one voice language, this can free up 3-12 GB of space instantly, and you can always re-download the packs later if you want them back.
Next, clear cached game data regularly. You don’t have to uninstall the whole game to do this. On Android, go to your app settings, find Genshin Impact, tap Storage, then select Clear Cache. On iOS, you can offload the app (which keeps your save data intact) then re-install it, which will wipe all old cached files. This usually frees up 2-3 GB of space with no effort, and it can even make the game run faster by removing old corrupted cache files.
You can also disable auto-download of resources. Go to in-game Settings > Other, and turn off the auto-download of new resources and event files. This way, you only download the content you actually want to play, instead of letting the game download every event file even if you don’t plan to participate. If you only play the main story and skip limited events, you can also delete old event files from the in-game resource management menu, which was added a few versions back to help players save space.
Never delete the core game files or your save data folder manually, because this can corrupt your account progress and force you to re-download the entire game from scratch. Always use the in-game deletion tools or your phone’s official app storage settings to make changes. I do a cache clear and unused resource delete once every two versions, and that keeps my total install size hovering around 18 GB, even after three years of updates. That’s 4 GB smaller than the average install size for long-time players who don’t do regular cleanup.
Pre-Installation Checks to Avoid Storage Headaches Later
If you’re installing Genshin Impact for the first time, or doing a fresh install to free up space, there are a few checks you can do first to make sure you don’t run into storage issues down the line. These simple steps will save you hours of frustration later when the next big update drops.
First, make sure you have twice the base install size free before you start downloading. When you install the game, your phone needs space for the installer file plus the unpacked game files, so if you only have 16 GB free for a 16 GB install, you’ll get an error halfway through. I recommend having at least 30 GB of free space on your phone before you start the download, so you have room for the initial install plus the next 2-3 version updates before you need to do cleanup.
Second, pick your preferred voice language before you start downloading extra packs. It’s tempting to download all voice packs upfront, but unless you actually switch between them regularly, you’re just wasting space. Stick to one voice pack at first, and add others later only if you find you want them. I made the mistake of downloading all four packs when I first started playing, and I didn’t even touch the other three for almost two years, so that was 9 GB of wasted space for no reason.
Third, turn off auto-updates for the game if you have limited storage. That way, you can choose when to install updates, and you can do a quick cleanup of old files before you download the new patch, instead of getting stuck with an unexpected download that fills up your storage overnight. If you have a phone with less than 64 GB of total storage, you can still run Genshin Impact, but you’ll need to do regular cleanup every 1-2 versions to keep the size under control. I know multiple players who play on 64 GB phones, and they just keep only Genshin and 2-3 other apps installed, plus they back up their photo album to cloud storage regularly to free up extra space.
At the end of the day, how much GB does Genshin Impact take on mobile depends a lot on how you play the game, what extra content you download, and how often you clean up old unused files. Fresh installs start around 15-17 GB, but long-time players can easily see that number climb to 25 GB or more if they don’t do regular maintenance. The good news is you don’t need to buy a new phone just to keep up with updates – a few small, regular tweaks to your storage settings will keep the game running smoothly without forcing you to delete all your other favorite apps. If you’re still running into storage issues after trying these tips, you can always stream the game via cloud gaming services if your internet connection is stable enough, so you don’t have to install any files on your phone at all.
