Aging iPhone? Speed it up with these 10 tricks

One of the big attractions of Apple’s iPhone is its smooth user experience. The iPhone often outperforms the competition, but every device begins to slow down with age. Updates to iOS can also be a double-edged sword, sometimes rendering older iPhone models even slower. It can be frustrating to find that your once youthful, lightning-fast iPhone is slowing to a crawl, but you don’t need to accept the decline. Don’t let your iPhone go gently into that good night. Instead, try out the tips below to give it new life.

Turn it off and on again

It’s the tried and tested opening gambit of IT support for a reason. Turning devices off and on again can often solve issues and boost performance. It’s also quick and easy, so what have you got to lose? Press and hold the Sleep/Wake button and slide the resulting switch to turn off your device. Once done, press and hold the Sleep/Wake button again until you see the Apple logo appear.

Turn off transparency and reduce motion

Reduce Motion

Visual effects may look nice, but there’s a processing overhead. You can speed things up a little by turning them off or reducing them. Go to Settings > General > Accessibility > Increase Contrast and toggle Reduce Transparency to On. You should also think about going to Settings > General > Accessibility and toggling on Reduce Motion.

Uninstall unused apps

Go through 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.

Turn Siri features off

Siri Settings

Siri can be very handy, but there are a couple of features that you might consider turning off to boost performance. Siri can automatically suggest things when you search in iOS 9 and up, but this feature can slow your iPhone down. To toggle it off, go to Settings > General > Spotlight Suggestions > Siri Suggestions.

Another feature that could be causing a performance hit is “Hey Siri.” If you have an iPhone 6S or 6S Plus, you can say “Hey Siri” at any time to bring Siri to life, and it works on some older iPhones when they’re plugged in and charging. If you want to turn it off, you’ll find it under Settings > General > Siri.

Turn off automatic downloads

If you take a look in Settings > App and iTunes Stores, you’ll find a section labeled Automatic Downloads. If your iPhone is the only device associated with your Apple ID, then you might want this on, but if it isn’t, then you could be automatically downloading new app and content purchases you made on another device that you really don’t want on your iPhone. If you are going to use automatic downloads, we’d suggest turning off Use Cellular Data in Settings > App and iTunes Stores.

Use default apps

This could be a real irritation for some people, but there’s little doubt that Apple’s apps work best with the iPhone. They’re set as defaults for most major functions, such as email, navigation, and Web browsing. They may not always be the best in terms of functionality, but if you want the smoothest and fastest performance, you should stick with them.

Turn off Background App Refresh

Background App Refresh

Some apps are constantly ticking in the background, syncing data and refreshing content without you realizing it. They can slow everything down and drastically reduce battery life. Contrary to popular belief, double-tapping Home and swiping everything up to close it, is not the answer.

What you should do is go to Settings > General > Background App Refresh and turn it off completely, or, at the very least, turn it off for select apps. The only difference is that the app will sync when you fire it up, rather than constantly syncing in the background.

Clear 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. Go to Settings > General > Storage & iCloud Usage > Manage Storage and you can see what’s taking up the most space. Delete anything that you don’t need. With some apps it may be worth uninstalling them and then reinstalling to get rid of the cached data.

Clear browsing history

Safari Clear

One area where it’s relatively easy to get rid of superfluous files is Safari. Go to Settings > Safari > Clear History and Website Data. This might slow down browsing in the short term given your iPhone will need to cache websites you visit again, but there will probably be a net performance gain in clearing out the junk every once in a while.

Reset your iPhone

You could try Settings > General > Reset > Reset All Settings. It’s something we recommend when troubleshooting and it will clear out some old data, at the cost of having to re-enter certain passwords and other settings.

A more drastic approach is to go for the full factory reset via Settings > General > Reset > Erase All Content and Settings. Check out how to factory reset an iPhone for full details. Doing so will likely result in improved performance — just make sure that you back up important files first.
