How to change Apple AirTag battery

So, first thing's first.

Based on official data, a fresh battery should last you about a year. Now, the performance of batteries is influenced by temperature. Considering the AirTag is so tiny, you can rest assured that the battery will feel the cold very, very fast, if the AirTag in particular spends is left outside in the winter cold. So, the battery might deteriorate quicker.

Thankfully, Apple has included a helpful battery meter in the Find My app, so you can check up on your AirTags' battery health regularly. Presumably we should also get a notification when one needs a battery swap.

It's actually fairly easy. You need to grip the AirTag and push in the metal part that is on its back. When you feel it giving a little, just twist counter-clockwise. The metal plate will jump out thanks to a pair of metal strips on the other side, which are constantly pushing into the battery.

It's a plain old regular "2032" coin-sized battery. You can find these basically everywhere — from grocery stores to gas stations.
