A newly installed Binance App takes up about 180MB of storage, but after a few months of use, you will often find that the app's total footprint has grown to 1GB or even more—this extra space is almost entirely cache and historical data. This article explains exactly where this space comes from and how to safely clear it. To get the latest version, you can first visit the Binance Official Site, or directly download the Binance Official App. iOS users unfamiliar with the process can refer to the iOS Installation Tutorial.
Base Installation Size of the Binance App
The installation package size of the latest Binance App is approximately:
- Android APK: About 150-180 MB (varies slightly depending on CPU architecture, with the arm64 version being slightly larger)
- iOS (App Store/Enterprise Certificate): About 180-220 MB
- iPad Version: About 220 MB (requires UI resources adapted for more resolutions)
After installation and extraction, the space occupied is generally 1.3 to 1.5 times the size of the compressed package, so the actual footprint after the APK is installed is about 200-260MB.
Why Does the App Get Larger With Use?
1. K-Line Historical Data Cache
Every time you open the K-line (candlestick) chart of a coin, the App will download and cache the price data for that period. Frequently viewed coins will accumulate a large amount of K-line cache: BTC, ETH, BNB, SOL, and dozens of coins you follow, each with minute, hourly, and daily lines. When added up, this can reach hundreds of MBs.
2. Market Chart Image Cache
The caches of icons, ranking images, and trend charts on the App's home page, major coin detail pages, and market leaderboards will also slowly accumulate.
3. Transaction Records and Order History
All your past orders, trades, deposits, and withdrawal records have a local cache in the App for quick viewing. Thousands of accumulated orders can take up tens to hundreds of MBs.
4. Notification History
The historical notifications of system pushes, price alerts, and event announcements are also kept locally.
5. Logs and Crash Reports
The App internally records running logs (used for troubleshooting and performance analysis). Normally these are very small, but if a large number of errors have occurred, the log files will bloat.
6. Web3 Wallet Related Data
If you use the built-in Web3 Wallet in Binance, the on-chain data for every chain and every token in the wallet will be cached. For multi-chain and multi-coin users, this part of the data is considerable.
7. WebView Core Cache
Web pages embedded in the App (such as announcements, the help center, and certain event pages) use WebView, and WebView itself has an independent cache space.
Adding all these up, it is very normal for the footprint of a Binance App that hasn't been cleared for half a year to grow to 1GB+.
Cache Clearing Methods for Android
Method 1: Clear Cache in System Settings
Settings → App Management → Binance → Storage
The page will display two items:
- App size: The size of the App itself (cannot be cleared)
- Cache: The cache accumulated by the App's operation (can be cleared)
Tap "Clear Cache". This will delete all temporary files, but will not affect the login status and account data.
Do not tap "Clear Data"—that will delete the login token along with it, and you will have to log in + 2FA again next time.
Method 2: Clear Within the Binance App
Some versions of the App come with a built-in clearing function:
- Open the App
- Go to "Profile" → Settings or About → Cache Management
- Tap "Clear Cache"
- Confirm
This method is safer, as it only clears the temporary files the App knows about and won't accidentally delete crucial data.
Method 3: Uninstall and Reinstall
The most thorough way. Note down your account information before uninstalling, and log back in after reinstalling. A freshly installed App is clean and takes up minimal space.
Cache Clearing Methods for iOS
The sandbox mechanism of iOS makes cache clearing more troublesome than on Android. The reason is that the iOS system does not provide a "Clear Cache" shortcut button for Apps, requiring the App to implement it itself.
Method 1: Clear Within the Binance App
Same as Android Method 2: Go to "Profile" → Settings → Cache Management → Clear. This is the most recommended method for iOS users.
Method 2: Check App Footprint
Settings → General → iPhone Storage → Find Binance
This will display:
- App Size
- Documents & Data
"Documents & Data" is the cache + local data. iOS does not allow clearing "Documents & Data" separately; to clear it, you must uninstall the App.
Method 3: Offload App but Keep Data ("Offload App" Option)
iOS has a special feature called "Offload App" (different from "Delete App"):
Settings → General → iPhone Storage → Binance → Offload App
This will keep the App's documents and data but empty the binary. Downloading the App again from the App Store later will restore the login state, but the cache will be reduced. Suitable for situations where you just want to save a little space and don't want to completely start over.
Method 4: Completely Delete and Reinstall
Long press the icon → Delete App. All data within the sandbox is emptied at once. After reinstalling, it is a brand new App with minimal footprint. Remember to confirm your account information before reinstalling.
Confirmations Before Clearing
1. Remember Account and Password
Clearing will not affect the server-side account, but the local login state will expire. Have the following ready:
- Registered email/phone number
- Login password
- 2FA device (Google Authenticator)
- 2FA backup code (just in case)
2. Do Not Clear "App Data"
On Android, "Clear Data" and "Clear Cache" are two different buttons. Only tap "Cache"! Tapping the wrong one might lose unsaved local settings.
3. Take Screenshots of Important Data in Advance
If you have some important transaction records/address books in your account that you wish to keep, back them up on the web version or another device first. Sync them again after clearing.
What Will Be Affected After Clearing?
What Will Change:
- Initial loading of K-line charts will be slower—data needs to be pulled from the server again
- Initial loading of coin list icons will be slower
- Entering a certain page for the first time will require requesting data again
What Will Not Change:
- Account assets - Not a single cent will change
- Historical orders - Fully preserved on the server
- Open orders - All are on the server
- 2FA bindings - Unaffected
- KYC status - Unaffected
- API Keys - Unaffected
- Notification settings - Mostly preserved
In short, clearing the cache is a safe operation.
Daily Space Management Suggestions
1. Clear Cache Once a Month
Regular clearing is more comfortable than ignoring it for a long time and doing a massive cleanup. Spend 1 minute at the end of each month going into the App to clear it.
2. Only Follow Frequently Used Coins
Reduce useless coins in your watchlist; every followed coin will generate a cache. Only keep the ones you actually trade.
3. Regularly Clear Notifications
Notification history will bloat if left uncleared for a long time. Go into the Notification Center and tap "Mark all as read + Clear empty".
4. Delete Unused API Keys Promptly
The API Key itself doesn't take up much space, but related logs will slowly accumulate.
5. Turn Off Extended K-Line Indicators
If you use a lot of custom technical indicators like MACD, RSI, BOLL, etc., these will also cache configurations. Turn off indicators you don't use.
Frequently Asked Questions
Q: Will clearing the cache delete my watched coins list?
A: No. The watched coins list is stored on the server; clearing the local cache does not affect it. The list will automatically sync back after restarting the App.
Q: What if iPhone cannot clear the cache separately?
A: Go into the settings inside the Binance App to find "Cache Management"; the App's own clearing function works. If all else fails, just uninstall and reinstall.
Q: Will clearing the cache affect the login status?
A: Generally not—a proper "Clear Cache" only deletes temporary files. However, if you tap "Clear Data", it will wipe the login state.
Q: Are the caches of the Binance App and Web3 Wallet cleared together?
A: Yes, they are together. The Web3 Wallet is a built-in module of the Binance App, and its cache will be cleared when the App cache is cleared. However, wallet private keys are not stored in the cache and will not be lost.
Q: Why does my App fill up with space again faster the more I clear it?
A: It means you use it very frequently. Opening it multiple times a day, looking at the K-lines of dozens of coins, and frequently placing orders naturally leads to faster cache accumulation. This is normal; you just need to clear it regularly.
