How to find my lost iPhone4S?

Okay, so i lost my iPhone 4S back around April. I'm almost certain that it's out of battery, and it did not have a SIM card. Would it have any way to track it and get it back?

Only it you have its imei number

Find my iphone if you had it on

If you have it's serial number or imei Apple might be able to help.
Someone is probably using it and have wiped it by now but it's worth a try.
