Part 1: Why Did My iPhone Turn Off by Itself Overnight?
Did your iPhone appear to turn off for a while overnight? Then you must be asking yourself, why my iPhone just
turned itself off? We are going to tell you why!
In this section, we will look at the possible reasons why your iPhone turns off for a while overnight.
It's possible that a bug in the iOS software is causing your iPhone to turn off unexpectedly. Apple releases regular software updates that include bug fixes and performance improvements, so it's important to keep your iPhone up to date.
Your iPhone's adaptive charging feature may be causing it to turn off overnight. This feature learns your daily charging patterns and pauses charging at 80% until you need to use your phone. This helps to extend the lifespan of your battery.
If you notice that your iPhone only charges up to around 80% and then pauses for approximately two hours before switching off, don't panic. This behaviour can be attributed to iOS's adaptive charging feature. So as unusual as it may sound, this is what your iPhone does to optimise battery health.
Another factor that can contribute to your iPhone turning off overnight is battery management. iOS includes advanced battery management features in order to prolong your iPhone’s battery life. These features monitor your usage patterns and adjust various settings, like background app refresh and display brightness, to conserve battery power. In some cases, these may result in your iPhone shutting down during the night to preserve battery life.
Also, if your iPhone's battery is old or damaged, it may cause the phone to turn off unexpectedly. You can check your battery health in the Settings app. If your battery health is below 80%, its time to replace your battery.
Software glitches can also cause your iPhone to turn off unexpectedly. These glitches can be caused by a variety of things, such as app conflicts, corrupted files, or hardware problems.
Your iPhone may automatically reboot overnight if there is a pending software update, background app activity, or a system maintenance process. This is usually normal, but if your iPhone keeps rebooting unexpectedly, it may be a sign of a problem.
Part 2: 5 Solutions| How to Fix iPhone Appear to Turn Off for a While Overnight
These are the solutions you can try if your iPhone shuts down while charging overnight.
- Solution 1: Charging iPhone When 30% or above
- Solution 2: Disable Battery Health Optimization
- Solution 3: Check If Any Updates Were Installed
- Solution 4: Force Restart iPhone
- Solution 5: Update to the later iOS Version
Solution 1: Charging iPhone When 30% or above
Instead of waiting for your iPhone's battery to drop to 20%, try charging it when it reaches around 30-40% battery life. This will make sure your iPhone has enough power to stay on for the rest of the night.
Solution 2: Disable Battery Health Optimization
iOS's battery health optimization feature is beneficial for extending your iPhone’s battery life span. But it might sometimes contribute to overnight shutdowns. This feature can cause your iPhone to turn off unexpectedly, especially if you have an older phone or a battery that is not in good condition.
To disable Battery Health Optimization,
- Go to Settings. Tap Battery.
- Then Battery Health and Charging.
- Toggle off the switch next to Optimised Battery Charging.
Solution 3: Check If Any Updates Were Installed
Regular software updates often include bug fixes and improvements that can address issues like overnight shutdowns. To check for updates, go to Settings, select General, and tap on Software Update. If any updates are available, install them to ensure that your iPhone is running the latest software version.
Solution 4: Force Restart iPhone
This can sometimes fix minor software glitches that may be causing your iPhone to turn off unexpectedly. Force restart shuts down all the background activities and apps on your iPhone and clears the memory caches. It won’t cause any loss to your device.
Here’s how you can force restart your iPhone when it just turned itself off.
1. Quickly press and release the Volume Up and Volume Down buttons one by one.
2. Press and hold the Power/Side button until you see the Apple logo on the screen.
3. Your iPhone’s screen will turn dark, and restart, keep holding the power button until you see the Apple logo screen.
Solution 5: Update to the later iOS Version
Apple releases regular software updates that include bug fixes and performance improvements. It's important to
