Is it possible to track an iPhone using another iPhone?

I recently misplaced my phone while traveling and really need a way to locate it using my spare device. I know about the native tracking features, but I am unsure if they actually work when the target phone is offline or completely drained. Can anyone confirm if cross-device location sharing still functions in those dead zones, or should I just download a dedicated monitoring app instead?

Native features won’t locate your phone if it’s offline or dead. A dedicated monitoring app might work if it has specific offline tracking capabilities, but most cannot provide real-time updates in those cases.
