How to clear your YouTube cache to improve performance – Business Insider
In normal day-to-day use, YouTube can store a considerable amount of data on your phone or computer. It does this to improve performance and run more efficiently, but over time you can lose many megabytes of storage space to YouTube.
If you need to reclaim that space — or if you are troubleshooting a problem with YouTube and you want to see if clearing the cache might resolve the issue — it’s simple enough to clear the YouTube cache. But the steps will vary depending upon whether you are using the YouTube app on your phone or the YouTube website in a browser.
If you’re using the YouTube app on an Android device, it’s very easy to clear the YouTube cache. On your phone, start the Settings app and tap Apps. If necessary, tap See all apps and then tap YouTube. Then tap Storage & cache, and then tap Clear cache.
Unfortunately, Apple doesn’t offer a one-tap method for clearing an app’s cache in the same way as you can do on Android, but even so the process is relatively straightforward. You need to delete the YouTube app from your iPhone, which doesn’t just remove the app, but also clears all the stored cache data at the same time. After deleting the app, simply reinstall YouTube from the App Store and sign back into your Google account.
If you’re using YouTube in a web browser, the cache works a little differently. Your Windows or Mac computer doesn’t maintain a separate cache for each website you visit. Instead, your browser has a single data cache that you can clear when needed, which you can generally find within the Settings menu in the browser. Here is how to clear the cache within Chrome, Firefox, Safari, and Microsoft Edge.
