Use Your Apple Watch to Find Your iPhone
Don’t you just hate when you’re about to leave home and you can’t find your iPhone anywhere? Fortunately, with an Apple Watch, you won’t ever have to worry about that again.
All you need to do is swipe up from the watch face on your werable to open the Control Center. From there, scroll down and find the ping iPhone button, which is the only one with the icon of an iPhone.
Tap it once, and your iPhone will emit a ping sound for a second or two. You can keep tapping the button on your watch as often as you need to while you track down your iPhone by sound.
Further — and here’s a real hidden gem most folks don’t know about — you can get a visual aid by long-pressing the ping iPhone button. Your iPhone LED flashlight will blink as your iPhone emits its ping sound.
