Many users have reported that the iPhone keyboard is lagging in iOS 15. Apple has come a long way in optimizing the software, and they have spent billions to ensure the stability of the basic features. I had an iPhone 3GS, and the iOS 6 keyboard was a little laggy. It was the last software update from the developer and the newer updates slowed down the device. Times have changed, and the developer is releasing stable updates that perform basic functions smoothly.

Why iPhone Keyboard Lags in iOS 15?

My intention is not to scare you, but there might be a software problem with the device. I’m asking you to back up the data and you can use iTunes or iCloud service. I will show you how to identify the culprit and resolve the choppy keyboard performance in the iOS device. We cannot eliminate the virus attack into the account and offer a solution below. I had a similar problem with the iOS 14, and I believed that it could be a hardware problem.

Fix iPhone Keyboard Not Working on iOS 15

My iPhone software was choppy, and I solved the problem by following the same solutions suggested below.

Restart iPhone

iPhone standby time has improved, and it drains less than 5% battery charge. Millions don’t turn off the iOS device, and they keep it in standby mode, which causes lots of software-related problems over months. It’s a good habit to switch off the iPhone from time to time, so it can cool off the internal components.

  1. Press and hold the Side or Sleep/Wake button for three seconds.
  2. Slide the power button right side to turn it off.
  3. Let iPhone stay in sleep mode for five minutes.
  4. Press and hold the Side or Sleep/Wake button until the Apple logo appears.

Give your smartphone a break, and it will end the session and dump the temporary files. The iOS system will boot drivers, tools, services, and apps.

Force Restart iPhone

The Cupertino-based manufacturer has programmed physical buttons, so you can force restart the iPhone. Yes, it won’t harm the device, and it may resolve the keyboard problem.

iPhone 6 Series or earlier:

Press the Sleep/Wake and Home buttons together and release the buttons when the Apple logo appears on the screen.

iPhone 7 Series:

Press and hold the Sleep/Wake button and Volume Down button for 15 seconds and release the buttons when the Apple logo appears on the screen.

iPhone with Face ID: 8 series or later

You have to follow different sets of instructions in the iPhone 8 or later devices.

  1. Press and release the Volume Up button.
  2. Press and release the Volume Down button.
  3. Press and hold down the Side or Sleep/Wake button.
  4. Release the Side button when the Apple logo appears on the screen.

Force restarts load the iPhone drivers, services, and important system files again.
