Is there another way to find my iphone?

I used phone finder app on my ipad and all it does is list its last location in my house, I searched all over and still can't find it, I called it from a friends phone and I goes to voice mail, the battery is obviously dead, are there any other options besides tearing the house apart, but it does need a good cleaning, guess I will have to search room by room, unless you good people have some advice

If it's powered down, than manual searching is the only option.

Sometimes you can get the time\date on the last location, which could give you more information if you think there's a possibility it would be somewhere else, since the phone doesn't always register tracking every-time you leave the house, but a dead phone can't be tracked. Regardless it sounds like it's in your house somewhere.

Look for it

No other way at this point
