Can I find my my lost iphone when its dead?
My phone is currently lost but it is offline since it is dead. Is there a way I can still locate this device or erase it while its still dead or offline?
iPhone 11, iOS 15
You may locate the iPhone by spotting it using your eyes.
You may erase it - which would occur if and when it awakens.
If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support
