iOS 12 is focused on increasing speed, performance and much more improvements. Unfortunately, there are users who experience a lag in their iPhone performance after the update. Here are some steps to fix the issue.
Step 1
Try ‘Updating’
Check if the version of OS installed is beta or regular version. If it is beta version, try updating it to a regular version of OS. Also, update apps that are not updated so that they don’t crash or lag frequently.
Step 2
Check ‘Battery Health’
Check 'Battery Health', lower the battery health would directly affect the performance of the device. In case you find your battery to be unhealthy, do replace it as early as possible.
Step 3
Reduce ‘Motion’
There are instances where animations on your phone that comes with the UI may slower your devices. Try disabling it. ‘Settings’ > ‘General’ > ‘Accessibility’ > ‘Reduce Motion’.
Step 4
Check ‘Storage’
’Settings' > ’General’ >’iPhone Storage’. Lack of optimum storage can drastically reduce the performance of the device. Every device need a buffer space to work efficiently. If storage isn’t the issue, then proceed to step 5.
Step 5
Try ‘Hard reset’
Hold the 'Home' button and the 'Sleep/Wake' button at the same time until the screen turns off and release the buttons once apple logo appears. This would reboot your device. Once it is rebooted, click on ‘Settings’ > ‘General’ > ‘iPhone Storage’ and make sure cache had been cleared and storage space has increased. If the issue still persists, proceed to step 6.
Step 6
Disable ‘Background App Refresh’
Some users install too many apps and if all the apps refresh once in a while in the background, there are high chances of phone getting slowed down. Disable background refresh for apps that is not important.
Step 7
Reset ‘Device’
When none of the above doesn’t help fixing the issue, backup all contents and erase the phone and restore backup. It is better to set it up as a new device so that any bugs or issues from the backups don’t get carried again to the device.
