Speed up your older iPhone with these simple tips and tricks

One of the big attractions of Apple’s iPhone is its intuitive user experience — it just works. The iPhone often outperforms the competition, but every device begins to slow down with age. New iOS updates can be a double-edged sword, sometimes rendering older iPhone models even slower. It can be frustrating to see your once new, lightning-fast iPhone slowing to a crawl. Instead, try out our tips below to give it new life.

What You Need

Tweak Transparency and Motion settings

Visual effects may look nice, but there’s a processing overhead. You can speed your phone up a little by turning them off or reducing them.

Step 1: Go to Settings > Accessibility.

Step 4: Another method involves Settings > Accessibility > Motion and toggling on Reduce motion.

Turn your handset off and on again

These simple instructions are the tried-and-tested opening gambit of hardware support staff for a reason. Turning devices off and on again can often solve problems and boost performance.

Step 1: Press and hold the Sleep/wake button and slide the resulting switch to turn off your device.

Step 2: Once done, press and hold the Sleep/wake button again until you see the Apple logo appear.

Uninstall unused apps

Review all the apps and games on your iPhone and uninstall anything that you don’t use regularly. Be ruthless. They’re taking up space and potentially eating resources by running and updating in the background.

You can delete apps on iPhone by tapping and holding until all the apps go into jiggle mode or just tap and hold on the app icon you wish to delete and remove it from the popup menu by choosing Delete app.

Update to the latest iOS

Apple introduces newer versions of iOS regularly, not only to bring in new features and better security but also to improve overall performance. Check to see if an iOS update is available, and update accordingly.

Step 1: You can do this by going to Settings > General > Software update

Step 2: Your iPhone will check for an update and will prompt you to Download and install if one is available.

Turn off Siri

Siri, Apple's personal assistant, can be handy, but there are a couple of features that you might consider turning off to boost performance.

Step 1: Siri can automatically suggest resources when you search in iOS 9 and later, but this feature can slow down your iPhone. To toggle it off, go to Settings > Siri and Search.

Step 2: If you have an iPhone 6S or newer, you can say “Hey Siri” at any time to summon Siri. You can turn off this feature via Settings > Siri and search and toggling off Listen for Hey Siri. Then, tap the Turn off Siri button.

Toggle off Siri.

Turn off automatic downloads

If your iPhone is the only device associated with your Apple ID, then you might want this on — or maybe it's not even needed.

If you own other Apple devices, you could be automatically downloading new apps and content purchases you made on another device that you don’t want on your iPhone.

Either way, to improve your iPhone's performance, you can shut down automatic background processes.

Step 1: Go to Settings > App Store, to find a section labeled Automatic downloads.

iPhone Auto Update setting.

Step 2: Toggle off Automatic downloads.

Toggle off Auto Downloads.

Use Apple's default apps

Apple’s apps work most efficiently with the iPhone. They’re set as defaults for most major functions, such as email, navigation, and web browsing. If you want the smoothest and fastest performance, you should stick with them.

Turn off Background App Refresh

Some apps are constantly ticking in the background, syncing data and refreshing content. This activity can slow everything down and drastically reduce battery life.

Contrary to popular belief, closing down all apps is not the solution.

Go to Settings > General > *Background app refresh and turn it off completely or turn it off for selected apps.

The only difference is that those apps will sync when you launch them rather than constantly syncing in the background.

Throw out old files

Whether it be a video file, a photo that’s safely backed up, an old text message, or cached data, old files that you no longer need are a pointless drain on resources.

With some apps, it may be worth uninstalling them and then reinstalling to get rid of cached data.

Step 1: Go to Settings > General > iPhone storage and you can see what’s taking up the most space.

Step 2: Delete any app that you don’t need by tapping on it and then choosing Delete app.

Clear browsing history

One area where it’s relatively easy to get rid of superfluous files is Safari. This might initially slow down browsing, given that your iPhone will need to cache websites you visit again, but there will probably be a net performance gain in clearing out the junk.

Go to Settings > Safari > Clear history and website data.

Reset your iPhone

We recommend resetting your handset when troubleshooting to clear out some old data, at the cost of having to re-enter certain passwords and other settings. Check out our guide on how to factory reset an iPhone or how to reset an iPhone for full details.

A general reset will likely result in improved performance — just make sure that you back up important files first.

Go to Settings > General > Transfer or reset iPhone > Reset.

A more drastic approach is to go for the full factory reset via Settings > General > *Reset > Erase all content and settings.

Put your iPhone in Low Data Mode

A feature of iOS 13 and later, Low Data Mode restricts background network use. When that setting is enabled, automatic updates and background tasks are paused.

Step 1: Start with Settings > Cellular.

Step 2: Then go to Cellular data options > Low data mode and toggle the Low data mode switch to On.

As great as the iPhone 14 and iPhone 14 Pro are, they're both already a few months old at this point, and the rumors about the iPhone 15 are well underway. We still have several months before the iPhone 15 models drop, though, as Apple usually makes iPhone announcements in the fall. In other words, there's still a lot of time for rumors to circulate around the internet.

We're keeping all of the reports and rumors of the iPhone 15 here in a single place for your convenience, but do remember to keep in mind that these are all still just speculation. Nothing is final until Apple confirms it during an official announcement. Still, a lot of the rumors give us an idea of what to expect each year, which is unfortunate if you like surprises. Here's everything we know of the iPhone 15 so far!

These Android apps are spying on you — and there’s no easy way to stop them
Illustration of a giant eye stalking through a phone

Android’s security woes need no introduction, but another threat that hasn’t received its fair share of awareness relates to spyware and stalkerware apps. These apps can secretly be installed on a victim’s phone to monitor their activity and can be exploited to harass victims of domestic abuse and engage in online stalking. All someone needs is physical access to the victim's phone to install these apps, which is not too difficult in cases of domestic abuse.

Call it an app-fueled version of AirTag stalking, but on steroids, because these spyware apps can steal everything including messages, call logs, emails, photos, and videos. Some can even activate the microphone and the camera, and secretly transfer these recordings to a remote server where the abuser can access it. Since Google Play's policies don't allow stalking apps, these apps are sold via third-party websites and need to be sideloaded.
