How do I find my iPhone from the iPad
I am not able to locate my iPhone from my iPad
Well, you already posted to tell us that you had a Best Answer, so this information is old news.
Open Safari on the iPad
Enter.....www.icloud.com/find
Enter your Apple ID and Password
IF....the phone still has good battery power.....AND....it is connected to the Internet, it will appear on the Find My map.
