Can you find Iphone with a dead battery?

I have the find Iphone app installed but I cloud doesn't seem to locate my phone or even the last place my phone was located when the battery is dead. Is there an app that can do this? And another question… Is there a way to not allow someone to turn off your iphone without entering the passcode?

No… GPS apps and 3rd party website tracking ONLY work if the phone is ON! No IFs ANDs or BUTs… It must be on… No power = no tower connection = no satellite connection = no tracking

question 2… No

No the phone has to be charged and yes you just press the turn off button like always.
