Re: changing batteries. - To change a battery, you need to not only see the notification but also be physically proximal to the device and have a fresh battery available. It can take some time to meet all these conditions and sometimes you simply forget. - A single air tag only needs the battery replaced roughly every six months. However, the rate of replacements increases as you are managing more air tags. It's easy to be replacing a battery every few weeks. - Replacement fatigue is a thing. At some point, we just get lazy. I keep my BBQ on my front patio, directly in front of my battery-powered Ring camera. The battery on that camera needs to be recharged and replaced every two months. I try to get to it as quickly as I can - ideally during the low-battery state and before the battery dies completely. One time, however, I got lazy/forgot. Two days after the battery died, my BBQ was stolen. Re: antitheft device You're right. Apple markets AirTags for recovering lost items, not stolen ones. Nevertheless, they can be very effective for recovering stolen items. My local police department will aid in recovering stolen property. If the item has an AirTag that pings a location, an officer will investigate. In the case of my BBQ, the officer was willing to look for it same-day but, alas, I did not have an AirTag on it. This product actually helps as it effectively hides the air tag. This makes it less likely that a thief would find and discard the airtag. They'd only be looking for it if their iPhone notifies them and, even then, they may not be able to discriminate which item contains the tag. Best case scenario: they discard the entire stolen unit, keeping the air tag with it.
