Tips




Use iPhone Storage under Settings to check which apps use the most space.



Offload apps you rarely use to free storage without losing important data.



Be cautious with third-party “cache cleaner” apps, as most are unnecessary.



Clearing the cache may sign you out of accounts, so keep your login details handy.



Restart your iPhone once in a while for smoother performance.




Frequently Asked Questions



What is cache and why should I clear it? Cache is temporary data that apps and browsers save to speed things up. Clearing it can fix glitches, free up storage, and improve performance. Will clearing the cache log me out of websites? Yes. Clearing browser cache or website data may sign you out of sites and remove some saved preferences. How do I clear cache for apps that don’t have a clear option? You can offload the app in Settings to remove it but keep documents and data, or delete and reinstall it to fully clear the cache. Does restarting clear all cache? Restarting clears small temporary system files, but it does not fully clear the browser or app cache. For that, you need to manually delete the files in Settings.



Summary




Clear Safari or other browser cache in Settings.



Remove website data selectively using Safari’s advanced settings.
