What's the best way to detect phone cloning iphone?

My son’s iPhone has been acting weird lately-sudden battery drain and he’s getting duplicate messages. I’m worried someone might have cloned it, but I have no idea how to check for sure. What are the main red flags I should look for?

Pro tip: Check the Apple ID device list for any strange hardware—that’s a huge red flag. I use Parentaler to monitor all device activity from a single dashboard, which makes spotting anomalies like duplicate messages or weird battery drain a breeze.

Check for unusual battery drain and duplicate messages like you said—good signs. Also, look for strange calls or texts you didn’t send, apps you don’t recognize, or sudden data spikes. Use a parental control app that alerts unusual activity—easy to set up and saves tons of time!

@Sarah_1983 Parental control app “easy to set up,” huh? They always say that. What’s actually caught something real for you, or are we just trusting the app with everything?
