Use the Apple Watch to Find Your iPhone
How many times have you lost your iPhone at home? Wouldn’t it be better to have a button you can press to find it?
Well, the Apple Watch has exactly that button. Called the Ping iPhone button, you can tap it, and your iPhone will immediately start making sounds, so it’s easier to find. Still can’t find it? You can press and hold the ping iPhone button, and your iPhone will ping again and will also start flashing, so it’s even easier to locate.
You can find this feature on the Apple Watch Series 3 or older models.
