How long does an AirTag beep last when away from me?

So I've just spent £20 (well £80 as I bought pack of four) on something designed to tell me if an item is under a cushion nearby. I can lift a cushion.

But it will beep in the theatre if my phone needs charging or is switched off or beep on a nightflight if my phone is in airplane mode.

"It is not meant to track people or pets, but to help you locate a missing item." What if your pet is missing, or your child? That is a big reason people purchase these. I put one in our car, (in case it goes missing) and on several instances the air tag will make a sound as we are driving down the ally away from our house. Not every time we leave home, but randomly. One thing I have wondered is because it was set up at our home, and uses that location for some reason. We purchased one for our son to attach to his dog's collar because she once escaped and was lost. Luckily he found her. He set the dog's air tag at his home, but we have been keeping his dog because their fence was damaged and she could escape. When he comes to visit her, he has told us sometimes his phone will alert him he has left her behind. This happens by it's self. In my reference the phone is in the same car as the air tag and it will sometimes make a tone.

I have two devices in my most expensive cars. Always I start to drive it also start beeping. My first idea was thats fine it says Hello to owner. But NO. It’s beeping when my girlfriend drives alone with kids. So it also say Hello Thief I’m somewhere here to track you🤦‍♂️ Really BAD when it can’t to be silent.

My airtags make the chirping sound and it sets off an alarm that sound like the Verizon ringtone on my Iphone XR almost every time I sit at our dinner table. And this is with the ringer TURNED OFF. It is horrible. It will occasionally do this in my car causing an accident hazard as my phone will not stop ringing until I wake it up and swipe up on the screen. HORRIBLE!

Nope

You didn't get it right.

If you use an airtag on something, you will be able to track it in the entire world, as long as other iPhones pass by ;)

Because it uses the cellular and location provided by any iPhone on the street, of course within the bt distance

Is the battery getting weak?
