Ways to Fix iPhone Auto Shutdowns, Power Failures, and Startup Issues
Method 1: Immediately Connect and Charge iPhone
One of the initial reasons to consider is a depleted battery causing the iPhone to shut down, experience power failures, and fail to start. To swiftly address this issue, connect your iPhone to a charging device to rescue it from this situation.
Note: When powering up your iPhone, it's crucial to use a standard iPhone charger to minimize errors during the device's charging process. If you're unsure how to differentiate between a standard and genuine iPhone charger, refer to the article on Identifying Genuine iPhone Charger.
Method 2: Execute the Hard Reset iPhone Trick
If your iPhone still fails to start after a period of charging due to auto shutdowns and power failures, the next step is to perform a Hard Reset on your iPhone using the physical button combination on the device.
- Hard Reset iPhone by pressing and holding both the Home and Power buttons simultaneously for about 10 to 20 seconds until you see the Apple logo appear on the screen, then release your fingers.
- For iPhone 7, 7 Plus devices, there's a slight difference in initiating Hard Reset. Press and hold the Power + Volume Down buttons together.
Method 3: Execute iPhone Restore
If Hard Resetting your iPhone hasn't resolved the issue of auto shutdowns, power failures, and failure to start, ensure your iPhone is charged. The next step is to proceed with iPhone Restore.
