How's everyones batteries holding up?

Just wondering how everyones AirTags batteries are holding up?

I got my AirTags on May 1st.

Ive got 1 on my work ID that has basically stayed on the same shelf since I put it on there due to WFH since the pandemic began - this has basically a full battery. I actually put it on there as I was worried I wouldn't be able to find it when it was time to go back to the office!

There is 1 in my wallet, which is maybe 1/5th depleted, I tend to use a card holder / Apple Pay most of the time so rarely take my wallet out and haven't yet repurposed the tag. Again it just sits in a draw.

I have 1 on my motorbike key which I use maybe 1/2 times a week, again less usage due to the pandemic. This is about 50% done.

And one on my house key, that just alerted me today its time to change the battery.

It seems to me, the more you use the item the tag is attached to, the more battery you use. Which makes sense as its working harder to constantly track the item and ping off of other iPhones out in the wild.

However we are looking at a life time of about 6 months so a 50% below what Apple say. So interested to see how that compares with your usage.

No issue, the batteries are a few pence each so I'll get that swapped out. Just an interesting observation.

Got two AirTags on launch day. The battery icon still shows as full on both of them.

One on my house keys still showing full/100%. So not sure if ‘the more you use the item’ theory works. I go out of the house 6 days a week. Sometimes 7. Always have my iPhone with me though.

All of mine are showing as full, except for the one that my girlfriend hid in the quarter-panel of her car. That one's likely down to about 80%. That's in line with what another user mentioned (they locked one in a safe) - the airtag is going to have some sort of mechanism about how aggressive it gets with reporting its location. Poorer signal strength of passing-by iPhones, it's going to use more battery to do the exchange of information by increasing its signal strength.
Where she put it is pretty tightly enclosed by metal.

In comparison, the one under the hood of my SUV is still 100%, but it likely gets great bluetooth signal through the grill as well as the nearby wheel well.

Received mine on launch day as well. Both show full battery.
