My iPhone lost when I was skiing. I think its in the snow and nobody can find it. I'm sure that my iPhone has about 40% charge but it turned off because of the freezing. Is there any way to find my iPhone with any apps when its off?
With the phone off there is no way to locate it from remote. And to be honest, a few days embedded in snow will not only kill the remaining charge in the phone but also the electronics itself (water will slowly get in).
