Many a time, simply restarting your iPhone is all that is needed to take care of minor issues with the software.

Here is how you do a soft reset of your iPhone.

  1. Press and hold on to the side button as well as the Volume Down button.
  2. The power slider should appear. Swipe to the right. This shuts down the iPhone.
  3. To restart again, press and hold on to the side button again until the Apple logo appears.

Clear apps running in background

Background apps are those that were used recently but have not been closed. Such apps run in the background so that the next time you need those, they will open almost instantaneously.

However, the benefit sometimes is outweighed by the negative impact it has on performance. Hence the need to close background apps.

  1. To close background apps, swipe up from the bottom and hold on for a while.
  2. You will get to see the apps open in the background.
  3. Now, simply swipe up on the apps to close them.

Manage iPhone storage

You needn't get into this unless you have limited internal memory to spare or the update in question has a complex assortment of files and is very large in size. Such files can clash with apps already installed on your PC, more so if you are low on memory.

A way out from this quagmire scenario is to lessen the app load by getting rid of those apps that you don't need anymore.

  1. To delete such apps, tap and hold on to the app icon in the Home screen.
  2. Hold on till the apps start to jiggle.
  3. At this point, tap on the 'X' mark in the corner of the app.
  4. Tap on Delete when prompted for the app to be permanently deleted from your device.

Sometimes, an update might alter your current settings to enforce some other settings that again could adversely impact your performance. In such a scenario, the best option will be to revert back to the defaults by resetting your iPhone.

Here are the steps to reset your iPhone.

  1. Go to Settings > General > Reset > Reset All Settings.
  2. Tap on Reset All Setting at the bottom. It's in red as a warning that all of your data is going to be deleted. So back Up before proceeding.

The above steps are time-tested to help deal with common issues with the iPhone software. Most of the time these are minor glitches and can be fixed easily with the above steps. At other times, Apple comes up with a fix with its next iOS update for errors that the previous update came with.

Then there also is the TinyFix tool that can be a sure-fire method of dealing with iOS glitches, easily and quickly. All of this can help save a visit to the Apple service center and a few bucks as well.
