If you’re upgrading to the iPhone 17 or installation the new iOS 26, there’s one tiny thing you should do first: clear your cache. It’s fast, painless, and it actually makes a difference.
I started doing this a few months ago as a Sunday habit, and my phone feels noticeably smoother.
Pages load faster, apps feel snappier, and those little Safari hiccups I used to blame on iOS are mostly gone.
New iPhones and iOS updates work best when your device isn’t carrying around old baggage.
Cache is basically digital clutter—tiny files from every website you’ve visited, images, scripts, cookies, trackers—all saved to make sites load faster next time. That works fine… until it doesn’t.
Most people spend more than five hours a day on their iPhone. Multiply that by months or years of browsing, and you’ve got a mountain of data slowing things down.
For iPhone 17, which will ship with the latest iOS update, clearing your cache is like giving your device a fresh coat of paint before you move in.
It frees storage, prevents minor glitches, and can even speed up your first-time experience on a brand-new phone.
How to clear Safari’s cache
To clear the cache on Safari, follow these steps:
Open the Settings app, scroll down, and tap Safari.
Next, tap Clear History and Website Data under the “History and Website Data” section.
You’ll have access to more refined options. The defaults are set to be very conservative, but feel free to dive deeper to customize things more precisely.
When finished, tap the Clear History button at the bottom.
This will log you out of websites, but your passwords and autofill info remain intact. It also clears cookies and cached images, which is the bulk of the data, slowing your phone.
If Chrome is your main browser
Not everyone is a fan of Safari. If Chrome is your browser of choice, here’s how you can clear its cache.
Open Chrome and tap the three dots in the lower-right corner.
Tap Delete Browsing Data.
Choose what to remove: browsing history, tabs, cookies, cached images, passwords, and autofill data.
Next, pick a timeframe. You can select All Time to start completely fresh.
Tap Delete Browsing Data.
Chrome won’t close your tabs, but when you revisit them, you’ll need to log back into sites. That’s the trade-off for a cleaner, faster browser.
Why this matters more than you think
Clearing cache is one of those things you don’t notice until you do it. After the first clear, Safari feels snappier. Pages load faster. Storage opens up a couple of gigabytes.
If you’re upgrading to iPhone 17, skipping this step is like moving into a new apartment without cleaning the old one first; you’ll inherit all the clutter and little annoyances.
Make it a habit. Even once a week or right before a major update can keep your phone running clean and smooth. It’s not glamorous, but it works.
So before you get your hands on the iPhone 17, take 15 seconds, clear that cache, and give your new phone the fresh start it deserves.
And now I’m curious: what tiny habits or tweaks do you use to keep your iPhone running like new? Let us know in the comments below.
