Is your iPhone browser slow? Try clearing your cache

If you’re still getting used to iOS26you may be wondering if the latest software update affects your iPhone daily performance. Is it just you, or are websites loading slower Safari Or another browser? Chances are the slowness isn’t due to Liquid Glass: you might just need to clear your cache.

Clearing your cache gives Safari and other web browsers a clean slate. It can improve performance, free up some storage space, and help fix annoying bugs like slow page loads or broken links. It’s not a complete system overhaul and it can’t make a 7-year-old phone feel new, but it can help improve your browsing experience.

Your browser cache is a bit like a digital mini-fridge. Whether you’re using Chrome, Safari, Firefox, or another browser, the cache stores page elements locally to speed up your next visit. It’s great for grabbing a digital snack or drink without having to trek all the way to the kitchen – at least, until the mini-fridge gets overloaded with expired foods, which in this analogy are outdated page elements.

Clearing your cache is like cleaning out that mini-fridge. You’ll have to restock it (your first visit after clearing your iPhone’s cache might be a little slower), but once you do, you’ll have a better experience than before.
