Many apps need location services. Google Maps can’t take you home if the app can’t locate you. Ride-sharing apps can’t track a ride in real time without GPS coordinates. But these location services don’t need to run 24/7.
If the iOS 16 is really slow, conduct a location permissions audit. You should quickly check which apps use location services, which apps can be switched off completely, and which apps can be switched to “While Using the App.”

5. Check your internet connection

“My iPhone is running slow after iOS 16 update,” often means, “the internet on my iOS 16 device is running slow.” So how to make internet faster on iOS 16? In most cases, slow internet isn’t a problem with the iOS 16 so much as with your Wi-Fi network or mobile data connection.
Here are a few ways to diagnose the cause of the iOS 16 slow internet connection:

Get a stable connection

If your Wi-Fi connection isn’t strong, you’ll see an immediate drop in internet speed. Make sure your Wi-Fi icon indicates a full-strength connection. If not, try toggling your Wi-Fi off and then on again. If that doesn’t help, move closer to your router or switch to mobile data.

Perform an internet speed test

A free online speed test will quickly assess your internet connection’s download and upload speeds. It’s a good way to confirm that you’re getting the speeds you’re paying for from your internet service provider (though Wi-Fi will always be slower than a direct Ethernet connection). Some speed test providers even have standalone apps for iOS and other devices.

Reset your network settings

Resetting your iPhone’s network settings can give it a fresh start with a faster internet connection. You’ll need to re-enter your Wi-Fi password when you’re done.

  1. Open your Settings app and go to General > Transfer or reset iPhone > Reset.
  2. Tap Reset Network Settings and enter your Passcode when prompted.
  3. Tap Reset Network Settings to confirm.

6. Reduce motion settings and screen brightness

A brighter screen takes up more energy and may be the cause of why the iOS 16 is slowing down. You don’t have to go full-on night mode, but a slight adjustment may help speed up a super sluggish iOS 16. Also consider turning off motion effects in iPhone settings to speed up iOS 16. Just note that reducing motion settings will affect autoplay videos and the user interface experience on some apps.
Here’s how to reduce motion settings in iOS 16:

  1. Tap the Settings app.
  2. Go to Accessibility.
  3. Select Motion to customize settings.
  4. Choose which of the four types of motions you want to adjust by toggling its corresponding tab from green to grey.

Here’s how to reduce screen brightness in iOS 16:

  1. Tap the Settings app.
  2. Navigate to Display & Brightness.
  3. Reduce screen brightness using the scroll bar and consider turning on Night Shift to automatically reduce brightness when natural light is dimmer.

7. Free up space to fix iOS 16 slow

Did you take a million photos today? Or worse, is the iOS 16 too slow because you need to remove bloatware or junk files? It’s time to learn how to clean up your iPhone.
Start by removing unwanted images and videos, then move on to deleting unused apps and bloatware. Dropping this extra weight can make the iOS 16 considerably faster.
Remember, hiding an app on an iPhone does not free up storage space.

8. Restore to factory settings

Is the iOS 16 so slow that none of these tips have made a difference? If the above strategies can’t help the iOS 16 speed up, you’ve got one more option: restoring your iPhone to its factory settings.
This is a last resort, because performing a full factory reset deletes all the data on your device. Back up any data you wish to keep to your iCloud account or on a computer or external hard drive before performing a factory reset.
Here’s how to perform a factory reset in iOS 16:

  1. Go to Settings > General.
  2. Select Transfer or Reset iPhone at the bottom.
  3. Choose Erase All Content and Settings, which will do exactly that — erase everything.

9. Disable some automatic background processes

We don’t recommend doing this unless you have a serious performance issue with your iOS 16 device , but you might be able to get more speed by shutting off tasks that the iPhone performs automatically in the background.

  1. Start the Settings app.
  2. Tap ”App Store,” and then switch off ”Apps,” and ”App Updates” in the Automatic Downloads section.
  3. Tap ”Back” to return to the main page.
  4. Tap ”General” and then tap “Software updates”
  5. Turn of “Automatic Updates“
  6. Tap ”Back” to return to the previous page.
  7. Tap ”Background App Refresh.”
  8. Tap ”Background App Refresh” and tap ”Off.”

10. Replace your iPhone’s battery

If you’ve had your iOS device for at least a couple of years, the battery might be reaching the end of its optimal performance life. Most iPhone’s batteries will last many years, but once they pass their peak performance capability, Apple may remotely throttle the performance of your iPhone to keep it from unexpectedly shutting down because the battery isn’t working properly.

To check on your iPhone’s battery health, start the Settings app and tap “Battery,” then tap “Battery Health.”

This screen shows you the maximum remaining capacity of your battery, and the “Peak Performance Capability” gives you an assessment of the battery’s overall health. If it says that the device is “currently supporting normal peak performance,” you don’t need to do anything. But if you see a message that your battery’s health is “significantly degraded,” you should consider contacting Apple support to replace the battery.

What to do if the iOS 16 is still running slow

If you’ve tried all of the above and the iOS 16 is still lagging, you may need to look for damage. If your iOS device has physical or liquid damage, it may not work properly. You may need to contact Apple Support for help.
