If your iPhone feels a little slow after updating to iOS 26, you’re not alone. Apple has packed the new update with plenty of visible features, but the real magic lies in the hidden settings that can make your device run much faster. These tweaks are easy, quick, and can instantly give your iPhone a performance boost.
Unlock the new Battery Boost Mode
iOS 26 introduces Battery Boost Mode, a hidden option that not only saves power but also optimizes performance. Older iPhones, especially models from iPhone X to iPhone 12, feel smoother when this is turned on.
- Go to Settings > Battery
- Toggle Battery Boost Mode
Turn off Background App Refresh
Background App Refresh constantly uses system resources. In iOS 26, you can disable it for non-essential apps to speed things up.
- Settings > General > Background App Refresh
- Choose Off
Reduce animations for instant speed
Apple’s animations look nice but can slow down transitions. In iOS 26, reducing motion makes apps open quicker.
- Settings > Accessibility > Motion
- Enable Reduce Motion
Clear app junk with Offload
Heavy apps like Instagram and Safari store cache that slows performance. iOS 26 makes the Offload App option smarter.
- Settings > iPhone Storage
- Select an app > Offload App
Auto-close Safari tabs
Browsing slows down when too many tabs stay open. iOS 26 now lets you auto-close them daily or weekly.
- Settings > Safari > Close Tabs
- Select After One Day
These hidden iOS 26 settings may not make headlines, but they can instantly speed up your iPhone and make it feel brand new. If you’ve updated, try these tweaks today and see the difference.
