But whatever the reason is, we come here to give you some tips and solutions to try and get rid of the overheating problem.

7 Tips to Fix iPhone Overheating after iOS 11.3 Update

1. Delete the Apps You Don't Offen Use

We love downloading a new app the moment we listen to something interesting about it. But here is a suggestion, if there are apps in your device that are not in use or you hardly use it, make sure to delete those. This is because all the apps keep running in the background which can be responsible for the overheating of the device.

2. Check Battery Usage

iPhone overheating issue on iOS 11.3 can emerge sometimes when there are a number of hidden apps running in the background as mentioned above. You can also check battery usage that will let you know which app is eating up how much amount of battery. This will also help you know battery life of your device.

  • So, go to “Settings” > “Battery” and wait until the device is reading the running apps.
  • You will find the apps now and how much battery each one is consuming. You can also go to “Last 7 Days” option to find the status of the battery eating apps within last 7 days.
  • Now, tap on clock kind of icon and you can examine the detailed information of the apps.
  • Lastly, when you found the apps’ status you can remove them by double clicking on “Home” button and swiping the apps and lastly flicking them up to delete them.

3. Stop Using iPhone When Charging

We agree that most of the works are done on hands these days. We can’t afford our phones to get apart from us even when they are charging. But using the device while on charge is like adding fuel to the flames. So, give some time to your device to get nourished as well and avoid using it when you have put it on charge which will eventually avoid iPhone overheating. Let it charge fully and then use it.

4. Turn Off Personal Hotspot & Bluetooth

If your iPhone overheating issue on iOS 11.3 is still not gone, check your Bluetooth and Personal Hotspot. Turn both the features off if they are not in use. You can run to the Control Center and turn the Bluetooth off by tapping on its icon and running to “Settings” > “Personal Hotspot” and toggling off the switch to disable it. This may decrease the heating because while they are turned on, they are in search of nearby devices all the time which may cause the iPhone to get hot.
