Good news: With iOS 15, iPhone models 11 and up will transmit their location even when powered off if you have already chosen to enable “Find My network” in your settings. How can I find my iPhone when it is turned off?

If you have AirTags, you’ll be familiar with how this works. It enables your device to send out end-to-end encrypted Bluetooth signals (“ like a lost cat meowing in the dark,” according to the Apple-focused tech site TidBits), and if certain other Apple devices with internet connections are nearby, they will anonymously pick up these signals and relay them to your Find My app as your device’s approximate location, without compromising your privacy. The Find My network is a secondary handy tool you can turn on for your phone that works with the Find My app. If you are part of a family-sharing group (a setting that allows an adult to add up to six family members to share apps, music, books and more), a family member can also help locate your phone by logging into their iCloud account and searching for your devices. If your phone is on Wi-Fi or on a cellular network, you’ll be able to hear it if it’s in earshot.

If your phone is set to vibrate, it will do that, too. A noise will toll, and the volume will slowly increase. If you’re on another Apple device (Apple Watch, iPad, etc.), you can also use Find My’s “find devices” feature to play a sound on your lost iPhone.
