Some iOS problems are as annoying as a sudden shutdown that stops your current activity
dead in its tracks.
Why do they just happen out of nowhere?
As far as we know, unexpected shutdown are mainly caused by battery problems, incompatible
apps, iOS system issues and more.
Welcome to Tenorshare channel.
In this video, I am gonna introduce several ways for you to fix the unexpected shutdown.
Method 1: Restart or Force Restart If it’s the first time that your iPhone
shuts down unexpectedly, you can try restarting it first.
There are cases that iPhone would shuts itself down under cold temperatures.
So in this case you need to restart it in a warmer environment.
If the restart fails, you might need to try a hard restart instead.There are different
ways to force restart different devices.
For iPhone 8 or newer, including iPhone SE (2nd generation), press and quickly release
the volume up button, press and quickly release the volume down button, then press and hold
the side button.
When the Apple logo appears, release the button.
For iPhone 7 or 7 Plus, press and hold both the volume down and the side button at the
same time.
When the Apple logo appears, release both buttons.
For iPhone 6 and 6s, including iPhone SE (1st generation), press and hold both the side
button and the home button at the same time.
When the Apple logo appears, release both buttons.
Take my iPhone SE 2nd generation for instance, volume up, volume down, then press and hold
the side button.
When the Apple logo appears, release the button.
Method 2: Useful Ways to Preserve Battery Life
iPhone unexpectedly shuts down might due to battery problems.
It is necessary for you to take some actions to preserve the battery.
First, switch off background processes.
Even when your iPhone links like it’s idling, it can be doing a lot of work behind the scenes.
These background processes include checking for new emails, weather, photos and more.
These apps will increase the drain on the battery.
Turn off unnecessary apps will be an effective way to make your iPhone battery last longer.
Second, turn off background app refresh.
Open settings and tap general.
Now tap background app refresh, turn this option off.
This will help you device prevent apps refreshing their content in the background and thus help
preserve battery life.
Third, enable low power mode.
Switching on low power mode will make the battery lasts for loner.
So it is a good habit that you turn it on when not dealing with heavy work on your phone.
Fourth, examine battery health.
Go to settings, battery, battery health.
If you see a very low maximum charging capacity of your battery, or a message saying that
the battery’s health is significantly degraded.
It can be concluded that the dead battery makes your iPhone turn off then turn on all
the time by itself with battery life remaining and needs to be serviced or replaced by Apple.
Method 3: Useful Ways to Fix iOS System Issues If everything goes normally with your iPhone
battery, the problem might be caused by iOS system issues.
