I Phone Power description

You haven't given us much to go on; identification differs widely among manufacturers. Adding pictures of the phone you have might help; someone here may own one of them and can identify it, or at the least we may be able to do photo searches to try and find a match.

Adding images to an existing question - iFixit Repair Guide

The site GSMArena.com has an extensive catalog of phones that could help. Is there any manufacturer information on the phone, such as Samsung, etc.?

Outside of that, an IMEI search can also tell you what the phone is, assuming it can be located. Many manufacturers engrave the IMEI number inside the SIM card slot; usually on the tray itself. If you find it, IMEIcheck.com should let you identify the phone.
