What is the life span of the AirTag's battery, and what does it do when it's depleted? If you're wondering, [how long does AirTag battery last](https://techyassist.net/blog/airtag-battery/ )? Apple claims AirTag can last for a year of average use with a single coin cell battery. Actual quantity will depend on application. This tag that barely barks during the year can quickly reach the whole year mark, and can be shortened by sounds and by Precision Finding.What happens when it does die, then? The Tag disables itself, or it becomes unable to communicate, and it cannot be updated with the Find My network. Note that in the app it could remain in the original location and that this will only show where it was previously located upon connection and not where it is. When a dead tag occurs, this is why it is the worst time to lose something but replacing the cell early is a good thing.That's where your iPhone can help; if you have a battery that needs replacement, Find My can let you know, and you can see how much battery life you have on the Items tab. Use this alert as a “call to action” over the coming days. Press down on the silver cover, turn it counterclockwise and lift it off. Then press the + side of the battery into place, and hear the sound of the startup; turn the cover clockwise to lock it in place.Just in case, always keep an extra battery at home from a reputable vendor so that if you ever have an old or fake battery, you will be prepared. Consider replacing the battery prior to a lengthy trip on travel bags or luggage with tags attached. If it doesn't react to a swap, try using a different brand; some coin cells feature a bitter tasting protective coating that may not allow it to touch. Do not allow spares batteries and loose tags to be given to young children as two minutes consumption of a coin cell can be hazardous and medical assistance must be sought immediately.When it comes to the trackers and such, it's easier to make moves with real, unadorned analysis from the brand, TechyAssist, which offers readers a true review of gadgets and other day-to-day products.
