Disable Automatic Downloads and Background App RefreshSettings → iTunes and App Store → disable “Updates” toggle
Background activity takes up some of your processing power in iOS. If you disable certain features, you might free up resources and thus enjoy a more smoothly running iPhone. We will begin by disabling automatic downloads for certain types of content, or all, if you choose so. Go to your “Settings” app, select “iTunes & App Store” and untick the toggle next to “Updates” to disable some of the automatic downloads, or all of the options. You can still download any of them manually.
Settings → General → Background App Refresh
Another feature that is quite handy and comfortable, but might be taxing on your iPhone battery life and performance, would be the so-called “Background App Refresh”. What this does is to fetch content that will be displayed within apps, so it is already there when you want to view it. While faster, it takes up resources.
Go to your “Settings” app, select the section labeled “General” and untick “Background App Refresh” either globally by tapping the switch at the top, or try a more selective approach by unticking any apps you don’t really need to update in the background.
Close unresponsive apps
Typically, your iPhone will manage all currently running tasks rather efficiently and requires little to no intervention. Some apps, however, tend to lock up and eat up system resources while backgrounded. This is especially the case with apps that rely knowing on your current location.
Double-tap the Home Button to view the app switcher. Then swipe up on the respective app to close its running process and terminate it.
Disable Wi-Fi searchSettings → Wi-Fi → Ask to Join Networks
While out and about, your iPhone will check for open wireless networks for you to join. To inhibit this behavior, we can disable a toggle that can be found in the “Wi-Fi” menu of your “Settings” app. Tap the switch next to “Ask to Join Networks” to turn this feature off.
Disable System ServicesSettings → Privacy → Location Services → System Services
A lot of the location-based “System Services” are not needed for the operation of your iPhone. We can disable them to conserve battery life and maybe even squeeze out an extra bit of performance. Go to your “Settings” app to begin.
Then navigate to the section labeled “Privacy”, select the “Location Services” and finally the “System Services”. Feel free to deactivate any of these features, while we suggest keeping on “Find My iPhone” at the very least.
Delete photos and videos
Getting rid of any photos and videos you don’t need will free up some space on your iPhone, which leaves more for the system to work with. Remember? Free space is always useful, as stated at the beginning of this guide. Tap the trash can icon and select e.g. “Delete Photo” to delete a single image. See this guide for more…
Reduce Motion and/or transparencySettings → Accessibility → Motion → Reduce Motion
This will probably have a very noticeable effect on your iPhone’s performance: The animation effects introduced in the latest versions of iOS surely take a toll on the processor and result in lag or stuttering on older hardware.
Luckily, Apple left us the freedom of disabling some of these effects by going through the accessibility options. To begin, open up your “Settings” app. Go to “Accessibility” and tap on “Motion”. Switch on the toggle next to “Reduce Motion” to disable the zooming animations and replace them with a smooth fade. Your iPhone should feel snappier pretty much right away.
Settings → Accessibility → Display & Text Size → Reduce Transparency
Another layer of effects is found in the Accessibility menu as well. Open the “Settings” app, go to “Accessibility” and select “Display & Text Size”. Then tap the button next to “Reduce Transparency”. This should also give your iPhone quite a boost.
Reboot your iPhone
Last but not least, it is always a great idea to reboot your iPhone from time to time, which will fix a lot of intermittent issues and clean up some of the caches.
Remember your Windows computer from a couple of years ago? It pretty much had to reboot for every other installation. Fortunately, iOS is a lot more advanced than the operating systems we used to work with in the past. Nevertheless, you can initiate a full restart by pressing and holding the Home Button and the Sleep/Wake Button for a couple of seconds, or until you see the Apple logo. Then let go of both buttons. Your iPhone might feel snappier afterwards, give it a try! If you have an iPhone 7, iPhone 7 Plus, iPhone 8, ihone 8 Plus or an iPhone X there is a different way to reset your iPhone.
