7 Hidden Settings Worth Changing on an Older iPhone
Story By Staff Reporter
Apple has unveiled the iPhone 18 Pro and the iPhone Duo, its first foldable. Alongside the new hardware comes iOS 27, which finally brings Siri AI to users. The update also delivers bug fixes, speed improvements, and better battery life for every iPhone from the 11 onward.
If your phone is too old for the newest software, a few buried settings can still make it faster and more dependable. The cutoff is the iPhone XS and earlier. The tips may also help newer models that could technically run the update but lack the 64GB of storage it requires.
Turn down Liquid Glass, Reduce Motion, and Reduce Transparency
If switching between apps feels sluggish and unreliable, cutting back on visual effects can help. On iOS 26 or iOS 27, start with Liquid Glass. Apple called this design language its biggest overhaul since iOS 7, but many people dislike it, and it appears to put extra strain on older hardware. Go to Settings > Appearance > Liquid Glass and drag the slider until the effect is tinted. You can also enable Reduce Motion from the Accessibility options on the same page.
If your iPhone can’t run iOS 26 or 27, Liquid Glass isn’t a concern. Instead, open Settings > Accessibility > Display & Text Size and turn on Reduce Transparency and Reduce Motion. Both make text easier to read and speed things up, since the phone skips the decorative animations when opening and closing things. Used together, these settings can also stretch your battery.
Restrict Background App Refresh and Significant Locations
If you haven’t replaced your battery, or the phone just feels slower than it used to, two settings deserve attention. The first is Background App Refresh, found under Settings > General > Background App Refresh. Newer iPhones have fast processors and at least 12GB of RAM, so background activity barely registers. Older models have less memory and aging chips, so it’s worth switching refresh off for nearly every app. Keep it on only for the ones you rely on, such as Messages and Mail. The rest will simply update when you open them.
The second is Significant Locations. Go to Settings > Privacy & Security > Location Services > System Services > Significant Locations to stop Apple from recording the places you visit often. The feature powers reminders and Maps suggestions, but on an older phone it costs more than it gives. Turning it off reduces background work, which helps both battery life and overall responsiveness.
Limit AirDrop to Contacts Only
Apple changed AirDrop’s behavior in iOS 16.1.1, reportedly in response to pressure from the Chinese government, aimed at stopping protesters from spreading material to large numbers of strangers. Under the new rules, you had to long-press AirDrop in Control Center and pick Everyone for 10 Minutes, because Contacts Only became the default. As attacks have grown more sophisticated, keeping AirDrop on Contacts Only also helps protect against zero-click exploits and stops pranksters from spamming phones in public.
If your iPhone hasn’t been updated to iOS 16.2, go to Settings > General > AirDrop and switch from Everyone to Contacts Only. That protects the phone from attacks and unwanted files. Users on the latest software get an added safeguard: even with Everyone for 10 Minutes enabled, the sender must enter a PIN shown on your device, and you decide whether they can send you a file once or as often as they like for 30 days. It may feel like a hassle, but it’s meant to keep devices safe.
Tune the Haptic Touch timing
Apple dropped 3D Touch in iOS 13 and replaced it with Haptic Touch. 3D Touch debuted on the iPhone 6S and responded to how hard you pressed, letting you preview links, play Live Photos, or use it as an extra control in games. Apple later retired it from newer models and disabled it even on phones that supported it. Haptic Touch kept some of the same functions, like link previews and Live Photos, but responds to how long you press rather than how firmly. On an older phone, wear can make the screen less responsive than when it was new, so the default timing may no longer feel right.
To adjust it, go to Settings > Accessibility > Touch > Haptic Touch and choose Fast, Default, or Slow. You can long-press the preview icon to test each option and avoid opening context menus by accident when you only meant to tap. Slow gives you more leeway before a press counts as a hold, while Fast helps if long-presses feel laggy.
Turn on Optimized Battery Charging
The final tip is Optimized Battery Charging. Find it under Settings > Battery > Charging. When it’s on, the iPhone holds off on finishing the charge until close to when you need it. If you charge overnight, the phone reaches 100% around the time you wake up, and it charges more slowly past 80%. That slows battery aging compared with leaving the feature off.
A battery replacement can also do a lot for an aging phone. Apple keeps adding battery-care features to newer models. It says iPhone 15 and later can handle up to 1,000 charge cycles before needing a new battery, versus about 500 for earlier models. The latest iPhones also let you set a Charge Limit between 80% and 100% under Settings > Battery > Charging. This is especially useful with a fresh battery, because it delays a full charge cycle each time and helps the battery last longer.
