A:AnswerNo, but you can log into any device that can access the internet and log in to iCloud.com or I use my Apple Watch. I ask Siri to find my iPhone. If it’s within range it will start playing a loud noise even if it’s on silent
A:AnswerYes, you can replace the batteries and these batteries don’t need to come from Apple. You just twist off the back of the tag, remove, replace and re-twist. I am not a handy gal, but this was not a problem for me.
A:AnswerAbout one year until battery replacement, which is alerted to you by the Find My iPhone app. Battery replacement was easy (twist off back of tag, remove old, put in new, retwist back on) and does require a special Apple battery.
