Your Samsung Galaxy S26+ uses cached data to make apps load faster, but over time, that temporary data can pile up and cause issues. If you're noticing apps crashing, general sluggishness, or getting low storage warnings, clearing the cache is a great first step. It's a safe way to free up space without deleting any of your personal photos, messages, or account information.
Use Device Care for a Quick Cleanup
The fastest way to clear cache on your S26+ is through Samsung's built-in tool. Swipe down and open your Settings, then tap Battery and device care. From there, tap the Optimize now button. This single tap will close background apps and clear cached data from across your system.
For a more detailed look, go into Battery and device care > Storage and tap Clean now. This targets junk files and app cache specifically. I'd run this once a week to keep things running smoothly, especially with a new phone like the S26+ where early One UI 8.5 software might have a few bugs.
Clear Cache for a Specific App
If one app in particular is acting up, you can target it directly. Head to Settings > Apps, then find and select the problematic app from the list. Tap on Storage, and you'll see two buttons: Clear cache and Clear data.
Always tap Clear cache first. This only removes temporary files. The Clear data option is much more drastic, as it will reset the app, deleting your login information and any saved preferences within it.
Clear Your Browser Cache
If you use Samsung Internet, open the app and tap the menu (three horizontal lines). Go to Settings > Personal browsing data > Delete browsing data. Make sure Cached images and files is checked, then tap Delete data.
For Google Chrome users, the process is similar. Tap the three dots in the corner, go to Settings > Privacy and security > Clear browsing data. Select Cached images and files and tap Clear data. Your saved passwords and bookmarks will remain safe.
Wipe the System Cache Partition
This is a deeper clean for the Android system itself, not your personal data. It's perfect for fixing odd glitches or lag after a software update. First, power your Galaxy S26+ completely off.
Press and hold the Volume Up button and the Side/Power button at the same time. When you see the Samsung logo, let go. You'll boot into a blue recovery menu. Use the Volume Down button to highlight Wipe cache partition, then press the Power button to select it. Confirm the action, then select Reboot system now.
Manage Messages and Media Storage
Your Messages app can hoard a surprising amount of cached media from group chats. Open the Messages app, tap the three-dot menu, and go to Settings. Look for an option like Delete old messages to automatically remove texts past a certain date.
You can also manually review conversations, long-press on ones filled with photos and videos, and delete them. For a broader cleanup, check Settings > Battery and device care > Storage > Clean now, as it often identifies large media files you can safely remove.
Restart Your Phone Regularly
It sounds too simple, but a restart clears out the phone's active memory (RAM) and some temporary system caches. Just press and hold the Side/Power button, then tap Restart on your screen.
If your phone is frozen and won't respond to the screen, you'll need to force restart it. Press and hold the Volume Down button and the Side/Power button together for about 10 seconds until the Samsung logo appears. This is different from the button combo for the recovery menu.
Set Up Automatic Maintenance
You can set your S26+ to handle some cleanup on its own. Go to Settings > Battery and device care and tap the three-dot menu in the top right. Select Automation and you can toggle on options like Restart when needed and Auto optimize daily.
Also, consider using Samsung Cloud or Google Photos to back up your pictures and videos. Once they're safely in the cloud, you can use the "Free up space" feature in these apps to remove the full-resolution copies from your phone's internal storage, leaving only smaller, cached thumbnails behind.
