If you’re having trouble turning off your iPhone 5s, there are a few things you can do. First, try pressing and holding the Sleep/Wake button until the “slide to power off” screen appears. If that doesn’t work, try restarting your phone by holding down the Home button and Power button at the same time until you see the Apple logo. If neither of those work, you can try deleting all of your apps and settings in Settings > General > Reset > Erase All Content and Settings. If that still doesn’t work, you can try restoring your phone to its factory settings by connecting it to iTunes and clicking on Restore. ..
